EQUIPMENT REQUIREMENT FOR COMMERCIAL KITCHENS
There are various heavy and light equipments required for the commercial kitchens. Determining the specific equipment required for the proposed kitchen is one aspect of design on which considerable time can be spent. During this part of the planning process the food service facility consultant has to estimate accurately the capacity of each of the various types of kitchen equipment to be used. If these capacity estimates are too low, the result will be delays and bottleneck in the food production process. Estimates that are too high will result in expensive and inefficient piece of equipment. The consultant should be careful to take into account any projected increase in business volume, that would require increased equipment capacity, and plan accordingly. At this juncture, he has to make decision about the manufacturer, the model number, attachments, special accessories.
A systematic method of determining equipment capacity required is to analyse each food item appearing on the menu. Whether a la carte (or) daily change menu as in the case of buffets a sample of the typical menus may be sufficient. First, we have to estimate the number of portions to be prepared for a particular period. This estimate is made for every menu item requiring equipment. Next the standard portion size of the each food item has to be fixed. For e.g. (soup-240 ml., coffee-180 ml., etc.) multiplying the estimated number of portions by the portion size will give the total volume if food to be prepared.
Once the volume of food to be prepared is arrived, the capacity of the equipment should be determined with future changes anticipated. Trends can be studied, and then any anticipated changes in foods, sales volumes or meals offered can be projected to see if drastic changes in equipment are necessary. For e.g.: perhaps no freezer space will be required currently, but if the need for freezer space is highly probable is 5 or 10 years, space can be left to add it then conveniently and economically.
The method of preparations and production for each item is then evaluated. Possible alternatives may include a) items individually prepared to order. b) Items prepared in small batches in anticipation of orders, c) item prepared in large batches, d) item that are partially batch prepared and finished when orders are received.
The batch size is next determined for those items that are to be prepared batches. The selection of the batch size is one way that the food service facility consultant can control the capacity of the equipment. Smaller and more frequently prepared batches are desirable because they require less equipment capacity and the foods are fresher when served. Some items that can be held swell after cooking can be made in larger batches.
For those items to be prepared and cooked to order, the maximum no. Of portion to be made at one time is evaluated on the basis of the no. of customers, their menu preference, their arrival pattern.
After determining portions, equipment catalogs may be consulted to match the capacity needed for production with the available sizes of standard equipment. The designer is also careful when sizing some equipment that may have a usable capacity that is somewhat less than the standard capacity.

A complete discussion of selecting and sizing of all the different types of kitchen equipments is beyond the scope of this study material. A brief discussion of frequently specified major items of equipments would serve to illustrate this part of the planning process.
A: DEEP FAT FRYERS:
Deep fat fryers are available in a variety of types, capacities and degree of automatic operation desired. The productive capacity of a fryer is related to the litres of fat in the fryers, the heat input, and the cooking time required for various foods. Typical designs of fryers are based on a fat-to-food ratio 6:1. This indicates that each kg. of food to be fried requires 6 lits. of oil (or) fat in the deep fat fryer. Conventional fryers are tailor made to the requirement of the client to various capacity, 1/2 lit, 1 lit. 3, 5, 7 and so on.
Pressure fryers make another category of deep fryers they are sealed to permit steam pressure to build up between the lid and the fat surface. The steam is generated from the foods fried or by water injectors. The pressure fryer reduces the loss of moisture from foods. Heat transfer in a pressure fryer is greater than a conventional fryer and consequently the cooking time is shorter. The food is brown outside, moist and juicy on the inside.
B. BRATT PAN (Tilting frying pan):
The brat pan is one of the most versatile pieces of cooking equipment. Its design is such that it can be used to boil, simmer, grill, sauté, fry and curries. For some items like Indian gravies, sambar, foogath can be done in the tilting frying pan with some savings in time that would normally be spent transferring foods and cleaning other utensils. Brat pan may be free standing; walls mounted, counter mounted and are available in gas and electricity model. There are models which are ignited by electricity and working on gas. The brat pan is tilted by a worm and gear assembly operated by hand wheel. They are tailor made to difference capacities of 50 litres. to 300 litres.
Griddle are flat top piece of equipment heated from beneath, as compared to grills which have heating sources both above and beneath. Griddles are used for high production food service and fast food operations. Grills are more of a specialty piece of equipment. Both gas fired and electric models are suitable for most purposes. Griddle are available in variety of sizes from small i.e. 10” x 20” to as large as 72” x 24”. Griddles are free standing, counter-mounted, mobile or built in as the situation demands. The height of the splashguard, location and the width of the grease trough should be considered when specifying griddles. Combination griddle-grill is also available. This provides greater flexibility for the preparation of different menu items.
Food cutters are versatile piece of equipment that can handle meats, vegetable and fruits. The food cutters can cut, dice, shred, and almost liquefies foods, depending upon the amount of time the food is left in the cutter. The foods to be size reduced are placed in a bowl, which rotates and exposes them to high speed rotating blades. Both bench and floor models are available. Some cutter models are equipped with an attachment hub for accepting various attachments.
E. STEAM JACKETED KETTLES:
Steam jacketed kettles are constructed of two stainless steel bowls sealed one within the other, with almost 2” of space between them for the introduction of steam. The amount of steam surface between the bowls is referred to as jacketing, and models from half-jacketed to full jacketed are available. The operation of steam-jacketed kettles utilizes steam, which is condensed back to water in the jacket to provide the heat for the inner kettle. A condensate line is provided to remove the water that accumulates. The amount of heat input is dependent upon the pressure and amount of steam allowed to enter the jacketed area. There is a pressure gauge to indicate the pressure. In case of excess pressure is let into the jacket, there is a pressure /air release valve to reduce the pressure. These kettles are used to cook rice, dhal, boil milk, and cook vegetables. They are available in 50, 100, 200 and 300 lit. cap.
F.GAS COOKING RANGE:
Gas cooking ranges have open top burners with high-pressure burners, T-22, T-35. They are tailor made for the client’s is requirement. They are manufactured in different combinations such as 2 in 1, 3 in 1, 4 in 1 and 6 in 1. The length and breadth of the range depends on the quantity food to be prepared. In case of a la carte preparation, a combination of high and low pressure burners is used, the area being 14”x 14”. The height of the cooking ranges 33” – 34”. But for ideal bulk cooking the length various between 20” to 24” per range, and. the height is reduced to 18” to 20”. Heavy gauge stainless steel and heavy-duty supports are used for these cooking ranges since it involves bulk preparation.
A Chinese gas cooking range is aptly designed for authentic Chinese delicacies, with a cast iron dome, to prevent the direct heat on to the chef while cooking with a wok. A 12” to 14” height splash back with a swivelling faucet with controls in front panel for immediate water, and a drain channel at the rear to enable to chef to empty the wastewater is also provided in this equipment. They are ideal with flat open top gas range in the middle for stockpot and dome cover gas ranges on either side for a la carte preparations.
G. DOSA PLATE:
The dosa plate are similar to the griddle which have hot plates specially designed to prepare dosas. The plate is thick machine polished, mild steel with even heat distribution for optimum use.
The M.S.plate rests on stainless steel frame, and it has S.S.top, front and a specially placed oil spillage trough. The splash back on all three sides of the dosa plate to avoid splash of oil or batter. For uniform heat distribution a “V” shaped burner is placed. This unit is available in electric/gas. It is custom-built size to prepare a minimum 2-3 dosas to 8-10 dosas at a time.
H. IDLI STEAMER:
Idly steamers are S.S. cabinets with tight fitting doors with gaskets. Steam is injected into the cabinet to pre heat to the required temperature. Idly plates are made of S.S./Alum. with different combinations. The steam is injected from the sides, top and bottom. These cabinets are tailor made to accommodate 2-4-6 idly plates at a time. It is advisable to have 2 plate compartments because steam is lost during the process of loading the idly plates.
