A large amount of fat, oil and grease (FOG) is produced by commercial kitchens and food establishments every day. If left untreated or not removed before joining the main sewage system, it can cause major issues with main sewers and a huge amount of disruption to businesses as it is cleared. In many countries, it is a legal requirement to install a suitable grease treatment system for effective removal of this material from wastewater from commercial hot food premises.
Grease Traps separate out solid material and fats from the water draining from dishwashers and sinks. They are installed between the sink or dishwasher and the drains, so that the wastewater flows through them and any solids and fats are stopped from entering the drainage or sewer system.
How Does A Grease Trap Work?
When the waste water from your kitchen enters the trap, it flows first through a sediment basket which removes larger solid particles. The grease in the water is less dense (“lighter”) than water and doesn’t mix with it, so it floats to the top. This allows the FOG to be separated from the water and the grease trap then lets the “cleaned” waste water flow to the drains.
Grease traps have to be cleaned regularly to remove these FOGS, otherwise, they build-up, and can eventually overflow through the outlet and even back-up through the inlet. This is why it is best NOT to use a waste disposal machine on the dish washing sinks, as this sends ground up food, including FOGs into the waste water system, which then has to be cleared using a grease trap. It is more effective to scrape any waste food into a bin before washing the dishes or adding them to the dishwasher. The FOG material can be disposed of or recycled. Walmart recycles the yellow grease from chicken rotisseries and this is converted to bio fuel. Alternatively, special cleaning materials can be used to reduce or prevent FOG build-up in internal piping. You should check whether these are allowed in your area, before using them. Not all water authorities allow their use.
Stainless Steel Grease Traps
Grease can eventually be corrosive to metals used in grease traps, this is why it is best to use stainless steel grease traps as these do not corrode and will last many years provided they are cleaned regularly.
Stainless Steel is not just one metal but a blend of iron with other metals, producing a range of corrosion resistant and high temperature steels. Stainless steel is a versatile material and can be used in many different applications. It is simple to keep clean, preserves its sheen and is also long lasting. It is 100% recyclable. Some stainless steels are magnetic, others not. Austenitics are the most typical variety of stainless steels. They are regarded as non-magnetic but might have a certain degree of magnetic response based on the way they happen to be produced. Martensitic stainless steels have corrosion resistance similar to austenitic varieties, but are capable of being hardened to even greater strengths. Stainless steel is a generic term for many different steels employed mainly because of their anti-corrosive properties. It’s easy to clean, tough, inert and hygienic. It is an extremely hard material that cannot be resized or changed once moulded and it is probably the most durable material obtainable for a variety of household and also commercial purposes.
Structural steel is used to create the frame or skeleton for most non-residential buildings constructed in the US. Steel is recyclable, and much of the steel produced comprises recycled material from old vehicles and demolished buildings. Structural engineers can access the latest version of the steel construction manual from the AISC to provide them with specifications and codes of practice when working with structural steel
Canopy Hoods or extraction canopies are often (though not always) made from stainless steel. These hoods are used to vent types of fumes such as heat, steam and odors from large or bulky cooking apparatus such as ovens and stoves. They generally have three main parts: a skirt or capture panel to contain the rising gases, one or more grease filters, and a fan of some kind for forced ventilation. Hoods can be installed on a wall or suspended from the ceiling for island cooking areas. Coupled with a blower and ductwork, extraction canopies can operate at a wide range of exhaust rates. These vent hoods can be custom designed to suit your kitchen. They provide excellent capture and ventilation of grease, fumes, and odors.
Commercial kitchen exhaust hoods are a vital part of commercial food preparation areas and the necessary ventilation systems but their importance is often underappreciated. Extraction canopies often have high-powered fans or blowers to remove greasy fumes, smoke and odors to improve the air quality inside your kitchen and reduce temperatures. This also reduces humidity which is important because this can encourage mold, mildew and bacteria growth, a big no no for health codes.
If you’re setting up a restaurant kitchen for the first time, or renovating an existing kitchen, the commercial kitchen exhaust hood is an important item to consider. It’s important to match the exhaust canopies or vents to the layout and operation of your kitchen to create a clean air environment for your patrons and staff.
Commercial vent hoods can also be combined with a replacement air fan that brings in air from outside, mixing it with the cooking fumes, to freshen the air in the kitchen. Extraction canopies can also contain filters to remove odors and grease.
With the addition of, say, glass or some wood, stainless steel makes great furniture, both for restaurants and for the home. Tough, yet beautiful, it stands up to hard wear and tear, while remaining beautiful. How many of us can say that? Pictured here is a chair, designed for a restaurant. Hard wearing, it will remain beautiful and easily cleaned, while providing sterling service in a busy commercial food serving business.
Coffee Table Meetings
The next photograph is of a customised coffee table, comprising three stainless steel cylinders, topped with safety glass. A simple, classic design redolent of the minimalist lifestyle so popular these days.
Dining In Style – Out Or In
Add a glass topped table to a set of stainless steel chairs and you have a clean, modern area for eating, whether in your own dining room or in a restaurant. The chairs can be produced as carvers (with arms), or without, or a mixture.
Tables can be produced at any height, for use as a telephone table, or a magazine disply unit, with a useful shelf below.
From large items to small, stainless steel is equally happy with the mundane tasks of supporting your curtains, with that extra pzazz you want in your stylish home.
Steel is a form of iron, with carbon added but this can rust easily in the air and moist conditions, if not protected. With the further addition of Chromium (minimum 10.5%), it becomes stainless steel. This was discovered through a happy accident. It was originally used for making cutlery but the range of uses has expanded greatly. The chromium that mixes with the steel forms a very thin layer of oxide on the surface of the steel which stops any further corrosion of the surface. Even if the material surface is cut or damaged, it can heal itself and it will remain corrosion resistant. The term “stainless” is now used to cover steel types and grades that are corrosion or oxidation resistant.
Stainless steel can be made stronger, more easily worked, or more resistant to cold by the addition of further elements, such as nickel and molybdenum.
Because stainless steel is so attractive to look at, has great resistance to corrosion and staining and is low maintenance, it is ideal for many applications. It is very versatile and easily worked. It can be rolled into sheets, for instance, or alternatively, made into plates, or bars. It can also be formed into wire and tubing for use in cookware, commercial kitchens, furniture, cutlery, surgical instruments, major appliances and also in construction projects. It is highly versatile. It is also used for industrial equipment, in tankers for chemicals and food products and also in chemical plants, paper mills, and water treatment and storage tanks for instance. Commercial kitchens and food preparation plants have been transformed by the use of stainless steel with its corrosion resistance, ease of cleaning and sterilization and because there is no need for other surface coatings.
Stainless steel is attractive, corrosion resistant, low maintenance and is strong.
