Glossary of Restaurant Equipment Parts - S


A sanitizer is a substance, or mixture of substances, that reduces the bacteria population in the inanimate environment by significant numbers, but does not destroy or eliminate all bacteria. Sanitizers meeting local health codes are generally used on food contact surfaces and are termed sanitizing rinses. The key difference between sanitizing and disinfecting is the type of chemical involved and how long it’s left on a surface.


A kitchen implement made of metal, plastics (such as polyethylene, nylon, or polypropylene), wood, rubber or silicone rubber. In practice, one type of scraper is often interchanged with another or with a spatula (thus scrapers are often called spatulas). Examples include the bowl scraper, dough scraper, grill scraper, plate scraper, pan scraper, shellfish scraper and srumb scraper. A "scraper" may also refer to a scraper blade.


A screw is a type of fastener, in some ways similar to a bolt typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out.

A screw drive is a system used to turn a screw. At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Other examples include Phillips head screws and screwdrivers, and Allen hex screws and wrenches.


A screen is physical divider intended to block an area from view or to block access.  Screens often provide protection or even filtration and may have holes or perforations allowing air or liquid flow.  A screen may also refer to a "touch screen" which provides a graphical user interface (a display device) which allows the user to interact with a computer or control by touching areas on the screen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.


A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pump system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets or o-rings.


A sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics (frequently a computer processor) or electromechanical components. A sensor is always used with other electronics or components serving as in input device or signal actuator. Sensors may be used to detect and measure temperature, pressure, humidity, voltage, amperage, viscosity, flow, motion, light, the presence of gasses or liquids, vibration, force, speed and more.


A separator is a machine or device that separates something into its constituent or distinct elements. A simple separator may be a mechanical device that collects items and sorts them by characteristics such as size or shape.  A vapor–liquid separator is a device used in several industrial applications to separate a vapor–liquid mixture. They are commonly used in refrigeration to separate moisture and oil vapor from coolants. A particulate separator collects small contaminants or byproducts where particles are suspended in some medium.


Serration generally refers to a saw-like appearance or a row of sharp or tooth-like projections. A serrated cutting edge has many small points of contact with the material being cut. By having less contact area than a smooth blade or other edge, the applied pressure at each point of contact is greater and the points of contact are at a sharper angle to the material being cut. This causes a cutting action that involves many small splits in the surface of the material being cut, which cumulatively serve to cut the material along the line of the blade.


A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it.


A schank is the long, narrow part of a tool connecting the handle to the operational end. A shank is frequently used with a faucet or dispensing control knob or handle. The unthreaded part of the shaft of a bolt is also called the shank.


Knife and blade sharpening is the process of making a knife or similar tool sharp by grinding against a hard, rough surface, typically a stone, or a flexible surface with hard particles, such as sandpaper.  Grinding is generally done with some type of sharpening stone. Sharpening stones come in coarse and fine grits and can be described as hard or soft based on whether the grit comes free of the stone with use.


A sheath is the insulating outer cover of an electrical cable or wire. A sheath, or sheathing, is used to protect the underlying cable from mechanical, moisture and chemical damage during the installation and service life of the cable or wire.


A sheave or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. The words sheave and pulley are sometimes used interchangeably.

Sheet Pan

A sheet pan, baking tray or baking sheet is a flat, rectangular metal pan used in an oven. It is often used for bakingbread rolls, pastries and flat products such as cookies, sheet cakes, Swiss rolls and pizzas.


Shelving used in foodservice storage and merchandising may be solid or wire. Solid stainless steel and wire shelving is used in a broad range of commercial applications. It is often used in restaurant, food service and retail store applications, as well as refrigerators and freezers, due to its ability to stay clean and resist rust and mold. A further finish on the steel may either be painted or sprayed on, or be it electroplated with zinc.


Generally, a shield is a protective plate or screen on machinery or equipment. There are various types of shields used in restaurant equipment from screw and bolt shields, splash shields, splatter shields, heat shields, burner shields, radiation shields, sneeze guards, frost shields, lamp and bulb shields, drip shields, and many others.


A shifter is a used to manually select a gear in the regulation of speed. The shifter (selector or handle) is often an external control mated to an internal yoke, index, cam, sleeve, and/or guide rod assembly.


A shim is a washer or thin strip of material used to align parts, make them fit, or reduce wear. Shims may also be used as spacers to fill gaps between parts subject to wear. On machinery installations (pumps, motors, etc.) the recommended practice requires new shims to be placed under every supporting foot. This guarantees flexibility for adjustments, like a slight raising or lowering of a motor, when parts of the machinery need to be replaced and aligned properly.


Shrouds are commonly used in foodservice equipment to protect sensitive components, especially electronic control boards. A shroud refers to an item that covers or protects some other object from heat, fluids, aerosolized grease, or vapor. Shrouds offer a supplemental protective feature by providing restricted access to moving parts (fan blades, belts, gears, motors) or extremely hot or cold components.


A shutoff is a device (a gate, valve, shaft, cam or breaker) designed to interrupt the flow of a solid, liquid, or a gas and in electrical components, the flow of current. Shutoffs may also be used as brakes in slowing or stopping the motion of a system or component. Shutoffs may be manually or automatically actuated in response to connected signaling or sensing systems.


A shutter is an implement or device used to close or open, or protect an opening, hose, drain, etc.  A shutters' position may be absolute or variably adjusted.

Sight Glass

A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.


A siphon is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came.


Slide or Door Slide or Drawer Slide are blanket terms used in the industry for all ball bearing slides, telescopic slides, drawer runners, linear slides, rails, and various other guides. Slides are used in refrigerators and freezers, merchandisers, holding and service cabinets and more. A slides movement describes exactly how the slide operates inside of the cabinet. Typically, this is either telescoping movement, which occurs in stages or progressive movement where the various slide members move simultaneously.


A slicer is a tool used in commercial foodservice, restaurants, butcher shops and delicatessens to slice meats, sausages, cheeses, bread and other products.  A slicer may be a stand-alone piece of motorized or mechanized equipment, or it may me as simple as a handheld knife.  Multi-purpose foodservice equipment will often have accessory attachments that include a slicing implement. 

Smart Card

A smart card, chip card, or integrated circuit card (ICC) is a physical electronic authorization device, used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both.

Sneeze Guard

A sneeze guard or sneezeguard is a plastic or glass screen designed to protect food from contamination. Sneeze guards are common in restaurants and buffets, and prevent pathogens from entering food through sneezing.


A snubber is a device used to suppress ("snub") a phenomenon such as voltage transients in electrical systems, pressure transients in fluid systems (caused by for example water hammer) or excess force or rapid movement in mechanical systems.


In restaurant equipment design, sockets are common engineering elements. In general, sockets are receptacles for matching parts, tools, and components. They may serve only for mounting purposes, or they may be used to form connections and provide a source of power.


Software is a collection of data or computer instructions that tell the equipment how to work. Examples in restaurant equipment are preset cooking modes, recipes, defrost cycles, and other automation instructions. Computer software includes programs, libraries and related data.

Solenoid Valve

A solenoid valve is electromechanically controlled for the purpose of generating a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it. That then opens or closes the valve automatically.

Solid State

Solid-state electronics means semiconductor electronics; electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used for devices in which semiconductor electronics which have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay. Examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD).


A spacer is a solid material used to separate two parts in an assembly. Spacers can vary in size from microns to centimeters. They can be made of metal, plastic, glass and other materials. Shapes include flat sheet, cylindrical and spherical.


A spatula is a broad, flat, flexible blade used to mix, spread, scoop, lift, hold, and fold foods, batters, and frostings. Spatulas are used to scrape the edges of a mixing bowl or to level off the top of a mixing or measuring cup. While frequently constructed of wood, spatulas are also made from heat resistant plastic or metal and may be solid or grated. Large platform spatulas may have an extended handle and deck and may themselves serve as a cooking platform.

Splash Curtain

Splash Curtains or Water Curtains may be found in dish machines, coolers, ice machines and more. Splash curtains promote energy efficiency and help eliminate water and condensation from escaping onto flooring and surrounding surfaces. Valuable heat can escape dishmachines and ice bins when worn curtains are being used. This drop in temperature will produce diminished warewashing and ice making results and increase overall energy costs. Similar cooling efficiency can be lost in coolers. Heavily soiled water curtains can also transmit mold and mildew ice or to wares coming out of the dishmachine and turn clean items into dirty ones.

Split Pin

A split pin, also known as a cotter pin or cotter key, is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types.


A spout is a tube or lip through which liquid or steam is poured or discharged. The projecting rim of an open container or the exhaust pipe of a piece of equipment.


A sprayer is a device used to spray a liquid commonly used for the projection of fluids such as water. Sprayers are fully integrated, mechanical systems, meaning they are composed of various parts and components that work together to achieve the desired effect, in this case: the projection of the spray fluid. 


A sprayhead an attachment to the end of a spray rod or hose that causes the liquid to be delivered finely and evenly as a spray. The spray may be very fine or more dispersed. The sprayhead may be fixed or it may be handheld with a storage or holding mount.


A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length.


A sprocket or sprocket-wheel is a profiled wheel with teeth, or cogs, that mesh with a chain, track or other perforated or indented material. The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.


Spud orifices are responsible for the amount of gas that flows to a burner. The orifice "regulates" or "limits" the transfer of gas by constricting the path through which the gas flows. They are brass fittings that screw into (spud) or onto (hood) gas valves. These orifices will have various hole sizes as as determined by the type of gas in use (either Propane or Natural Gas).


A standoff is a device which maintains a fixed distance between two objects. In machinery it is a threaded separator of defined length used to separate one part in an assembly from another. They are usually round or hex (for wrench tightening) and often made of aluminum, brass, or nylon. In electronics they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing electrical shorts. When used to fasten cable connectors together, they are called jack screws.


In plumbing, a standpipe is a vertical vented pipe attached to a trap that permits rapid wastewater discharge without disrupting the water seal of nearby traps.

Start Component

Start components (start capacitor) are used to assist the compressor (or motor) on startup. This is added to the circuit along with a potential relay. The potential relay is necessary because to isolate the start capacitor from the compressor circuit after the compressor starts. The potential relay allows the start capacitor to assist the compressor to start. It then opens the circuit between the compressor and the start capacitor after the compressor starts and is running. The potential relay does this using back EMF or back electromotive force, otherwise known as "back voltage" coming from the compressor. As the compressor starts and voltage goes through the system, it sends out a back EMF voltage. Furthermore, this voltage energizes the coil in the potential relay for the start capacitor. The back EMF is constant while the compressor is running. The potential relay will hold the start capacitor out of the compressor circuit because of the Back EMF until the compressor stops. Then the coil in the relay is de-energized and the start capacitor awaits another startup.


The stator is the stationary part of a rotary system, found in electric generators and electric motors around which a rotor revolves. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current.


A stop is a part designed to restrict the movement of a rotary mechanism, linear (sliding) mechanism or its components. It protects a mechanism from loss of adjustment or damage due to extreme movement. A stop or stopper may also be designed to calibrate and halt the flow of solids, liquids or gases.

Strain Relief

Cable management refers to management of electrical or optical cable in a cabinet or an installation. The term is used for products, workmanship or planning. Cables can easily become tangled, making them difficult to work with, sometimes resulting in devices accidentally becoming unplugged as one attempts to move a cable. A strain relief or cable gland can provide protection to the wires and cable by securing the cable to the panel of the equipment. It helps to protect from stress and damage as well as unintended disconnection.


A stud is a threaded rod is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. They are designed to be used under tension. Threaded rods in bar stock form are often called "all-thread".


A mesh strainer, also known as sift, commonly known as sieve, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal. The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate solids from liquid.

Suction Cup

A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum.


The stator is the stationary part of a rotary system, found in electric generators and electric motors around which a rotor revolves. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current.

Suction Line

In refrigeration and air conditioning systems, the suction pressure (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. The suction line is a tube that conveys the refrigerant vapor from the evaporator outlet to the suction inlet of compressor.


A transient voltage suppressor or TVS is a general classification of an array of devices that are designed to react to sudden or momentary over-voltage conditions. One such common device used for this purpose is known as the transient voltage suppression diode designed to protect electronic devices against over-voltage. Another design alternative applies a family of products that are known as metal-oxide varistors (MOV) that protect electronic circuits and electrical equipment. Voltage suppressors act a circuit breakers. Voltage suppressors can also be non integrated electronic noise suppressors.

Surge Protector

A surge protector (or spike suppressor, or surge suppressor, or surge diverter) is an appliance or device designed to protect electrical devices from voltage spikes.


In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electro-mechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching, current can pass between them, while when the contacts are separated no current can flow.


A switch plate is a housing or covering of a control panel enclosing and protecting internal components from elemental damage and providing safety from accidental contact with moving, hot or electrified components. Switch places are often printed or embossed with dial guide measurements or operating settings.
