How to Use a 3 Compartment Stainless Steel Sinks

A 3-compartment sink is designed for usage in professional kitchens. It contains 3 discrete bowls, which are deep and spacious for mass dishwashing. It allows for more than one person to use it without crowding. Every compartment or sink has a specific usage.

The FDA requires commercial food establishments to thoroughly clean and sanitize dishes they use in food preparation and serving. Cleaning and sanitizing refer to 2 separate functions to kill invisible bacteria.

Each sink should be labeled to help your staff remember the required order.

Sink 1

Compartment or sink 1 is used to scrub or soak the dishes in hot, soapy water at a minimum temperature of 110oF. The staff should wear protective gloves to prevent skin damage. This sink is basically used for scouring the utensils with a scrubbing brush or scouring pad.

When the water becomes dirty, drain it and replace it with the appropriate clean hot water and detergent mix.

Sink 2

This compartment is used for rinsing the dishes. It should be filled with hot, clean water (no detergent needed). The second sink’s purpose is to eliminate the detergent residues on the kitchen utensils and prepare them for the third sink.

When the water becomes soapy, fill it with fresh, hot water again.

Sink 3

In this sink, sanitization takes place. The two options are to use boiling water (171oF or above) or sanitizing chemicals to destroy any remained germs.

You can mix the boiling water and chemicals in a dispenser or manually prepare the mixture according to the instructions for the best results.

When using only hot water, make sure you maintain the appropriate water temperature and check it with a thermometer.

Sanitizing chemicals in common use are:

  • Chlorine solution – it is the cheapest option and requires a water temperature of 75-120o
  • Quaternary solution – requires 75-90o
  • Iodine solution – requires 75o

The dishes must remain submerged in the solution for at least one minute, whichever sanitizing solution you choose. Check the concentration levels, inform your staff to check the manufacturer’s instructions on the amount required. You will avoid using it excessively or less than needed.

When finished, place items upside down so they will drain and let them air dry.

3 Compartment Sink Main Features

Materials

When talking about materials, stainless steel is the material used for all commercial sinks. Stainless steel is often an iron-carbon-chromium-nickel alloy, which adds some desirable properties. It includes corrosion, high and low-temperature resistance, durability, high tensile strength, low maintenance, and recyclability.

There are two main types of stainless steel used for industrial kitchen sink production:

  • 430 is a straight chromium alloy with the ability to resist nitric acid attacks. It is less formable and less weldable stainless steel and does not do well at cryogenic temperatures. However, it is an inexpensive stainless-steel grade.
  • 304 is the most common commercial-grade alloy. It contains around 18% chromium and 8% nickel. As a result, it has excellent corrosion resistance, together with a significantly improved ability to be welded and cold-formed. However, it is more expensive than 430 stainless steel because of the added nickel.

Overall, experts advise you to buy a 304-steel sink because of its high-quality properties and rust resistance.

Gauge

Besides the type of stainless steel, a gauge is one crucial factor you need to consider. It refers to steel thickness, and there are 3 main types of gauge metal:

  • 14 gauge steel is the thickest type, also the toughest. It has excellent durability and is appropriate for hard water areas.
  • 16 gauge steel is a medium-grade steel thickness and hardness, appropriate for sinks that require strong legs.
  • 18 gauge steel is a good grade thickness suitable for soft water areas. In addition, it is the thinnest material.

Types

When talking about models, you can choose the option that best fulfills your food business needs. There are 3 styles available:

  • Sink without drainboards is the best option for a small-volume business with limited kitchen space, like clubs or bars.
  • A sink with 1 drainboard is ideal for drying dishes or pilling up dirty ones; it requires more space.
  • Sink with 2 drainboards offers the biggest working space for clean or dirty dishes on both sides of the sink.

The backsplash guard is an important part of the 3 comp sink.  It is necessary for wall protection and easier cleaning. Most sink backsplash dimensions vary from 4.5″ to 11.75,” and the most common size is 7″.

The faucet is the essential part of the triple sink because, without it, the sink is useless. So many different types and faucet designs exist; they can be wall-mounted or deck mounted (mounted on the top of the sink deck). Four main types of faucets are:

  • Standard swing spout allows you to move the nozzle to get water in each section.
  • The workboard faucet is the model with risen escutcheon below the handles and spout. It is as efficient as the previous type.
  • Gooseneck faucets make more space for the larger dishes and pots.
  • The pre-rinse faucet has a high-arc spout with a high-pressure pull-out spray nozzle to blast off food from plates.

Most 3 compartment sinks have wide bowls, but bowl depth differs from sink to sink. A deeper bowl can hold more water or dishes but can require you to lean over to access it, especially if the sink is shorter.

NSF Certification

Choosing an NSF-certified sink is a must. That means that a product fulfills rigorous standards for public health protection.

NSF certification guarantees that the sink has interior corners of the bowl rounded to allow thorough cleaning and bacteria removal. In addition, there must be a tapering of the bottom of the sink towards the drain.
