Tools and Equipment Chapter 3 Copyright 2011 by John Wiley & Sons, Inc. All Rights Reserved Slide 2 A thorough knowledge of equipment is essential. All kitchen personnel need to be orientated on the proper usage, cleaning, and safety of all equipment. Modern cooking and food processing equipment has an extraordinary capacity to burn, cut, smash, mangle, and amputate parts of the tender human body. Never use a piece of equipment until you are thoroughly familiar with its operation and all its features. You must learn how to know when a machine is not operating correctly. 2 Tools and Equipment Slide 3 Not All Models Are Alike It is important to study the operating manual supplied with each item or to be taught by someone who already knows that item well and has operated it. 3 Tools and Equipment Slide 4 Cleaning is part of the operating procedure! Thorough, regular cleaning of ALL equipment is essential. Most large equipment can be partially disassembled for cleaning. Operating manuals should describe these procedures in detail. 4 Tools and Equipment Cleaning Slide 5 Look for equipment models that have been tested and certified by recognized agencies that certify products and write standards. 5 Tools and Equipment Cleaning Slide 6 Know the preheating time for all your cooking equipment so you dont need to turn it on before necessary. Plan production so equipment that requires a lot of energy is not on for long periods when not in use. 6 Tools and Equipment Conserve Energy Slide 7 Machines are intended to be laborsaving devices. The usefulness of specialized processing equipment depends on the volume of food it handles. It takes less time for certain preparations to complete by hand, versus setting up, using, breaking down, and cleaning equipment. This is why it is important to develop good manual skills. 7 Tools and Equipment Your Hands Are Your Best Tools Slide 8 The range is still the most important piece of cooking equipment in the kitchen. Many of its functions have been taken over by other tools such as steamers, steam kettles, tilting skillets, and ovens. 8 Cooking Equipment Rangetops Slide 9 Open Elements 9 Cooking Equipment Rangetops Either electric coils or gas flames. Fastest to heat and can be turned off after short use. Cooktop space is limited to one pot per burner. Slide 10 Flattop or Hot Top (lightweight) 10 Cooking Equipment Rangetops Burners covered with steel plate. More cook space is available. Top supports moderately heavy weights. Slide 11 Heavy-duty Flattop 11 Cooking Equipment Rangetops Burners covered with heavy cast steel. Top supports many heavy pots. Requires longer preheating. Ring-top range is a type of flat top that has removable rings. Allows access to more intense heat from the flames below. Slide 12 Induction Cooktop 12 Cooking Equipment Rangetops Top of an induction unit does not become hot. Works by magnetically agitating the molecules in steel or iron cookware. Aluminum pots and pans sandwiched between layers of stainless steel will also work. Much less energy is used. No open flame; kitchen stays cooler. Only pots, pans and their contents become hot. Slide 13 The oven and the rangetop are the two workhorses of the traditional kitchen. They are often found in the same unit. 13 Cooking Equipment Ovens & Rangetops Slide 14 Enclosed spaces in which food is heated, usually by hot air. Or, by microwaves or infrared radiation. Used for roasting and baking. Foods can also be simmered, stewed, braised, or poached in the oven. This helps to free up the rangetop and the chefs attention for other tasks. 14 Cooking Equipment Ovens Slide 15 Ovens for high volume or specialty use: Conveyor oven: carries foods through the oven on a steel conveyor belt. Holding oven or warmer: designed to hold foods at serving temperatures for extended periods without drying out or overcooking. Roll-in oven: high-volume oven with large doors into which one can roll carts loaded with trays of food. 15 Cooking Equipment Ovens Slide 16 Conventional Ovens Operate simply by heating air in an enclosed space. Most common ovens are part of the range unit. Separate oven units or ovens as part of a broiler unit are also available. 16 Cooking Equipment Ovens Slide 17 Stack Ovens Consist of individual shelves or decks arranged one above the other. Pans are placed directly on the oven deck. Temperatures are adjustable for each deck. 17 Cooking Equipment Ovens Slide 18 Convection Ovens Contain fans that circulate the air and distribute the heat rapidly throughout the interior. Foods cook more quickly at lower temperatures due to the forced air. Shelves can be placed closer together than in conventional ovens without blocking the heat flow. 18 Cooking Equipment Ovens Slide 19 Revolving Ovens Large chambers containing many shelves or trays on an attachment like a Ferris wheel. Also called reel ovens. Slow-Cook-and-Hold Ovens More sophisticated features. Computerized electronic controls. Special probes that sense when a roast is done and tell the oven to switch from cooking temperature to holding temperature. 19 Cooking Equipment Ovens Slide 20 Combination Steamer Ovens Also called a combi oven. Can be operated in three modes: as a convection oven as a convection steamer as a high-humidity oven 20 Cooking Equipment Ovens Slide 21 Barbecue or Smoke Ovens Are like conventional ovens. Produces wood smoke, which surrounds the food. Adds flavor while it bakes or roasts. Special woods such as hickory, mesquite, or fruitwoods such as apple or cherry must be added. 21 Cooking Equipment Ovens Slide 22 Infrared or Reconstituting Ovens Contain quartz tubes or plates that generate intense infrared heat. Used primarily for reconstituting frozen foods. These ovens bring large quantities of foods to serving temperature in a short time. 22 Cooking Equipment Ovens Slide 23 Woodburning Ovens Ancient ovens were made of heavy masonry, brick, or clay. Heated by building a wood fire inside them. Woodburning ovens have once again come into fairly wide use. 23 Cooking Equipment Ovens Slide 24 Microwave Ovens Special tubes generate microwave radiation. Create heat inside the food. 24 Cooking Equipment Ovens Slide 25 Sometimes called overhead broilers. Generate heat from above. Food items are placed on a grate beneath the heat source. Cooking Equipment Broilers and Salamanders 25 Slide 26 Same cooking operations as broilers. Heat source (gas, electricity, or charcoal) is below the grid that holds the food. Charcoal taste is created by smoke from meat fats that drip into the heat source. 26 Cooking Equipment Grills Slide 27 Flat, smooth, heated surfaces on which food is cooked directly. Available as separate units or as part of a rangetop. 27 Cooking Equipment Griddles Slide 28 Cooks meats and other foods by turning them slowly in front of electric or gas-powered heating elements. Especially suitable for chicken and other poultry. Can be used to cook any meat or other food. Drip pans catch juices, which can be used for basting or making gravy. 28 Cooking Equipment Rotisseries Slide 29 Cooks foods in hot fat Standard Deep Fryers Powered by either gas or electricity. Thermostatic controls maintain fat at preset temperatures. 29 Cooking Equipment Deep Fat Fryers Slide 30 Automatic Fryers Remove food from the fat automatically after a preset time. Pressure Fryers Covered fry kettles that fry foods under pressure. Foods cook faster. 30 Cooking Equipment Deep Fat Fryers Slide 31 Also known as: Tilting brazier and tilting fry pan. Has a tilting mechanism that enables liquids to be poured out of it. Can be used as: a griddle fry pan brazier stewpot stockpot steamer bain-marie or steam table 31 Cooking Equipment Tilting Skillets Slide 32 Heated not just on the bottom but on the sides as well. Heats much more quickly. Has more uniform and controllable heat than pots on the range. 32 Cooking Equipment Steam-Jacketed Kettles Slide 33 Tilt or Trunnion Kettles can be tilted for emptying. Non-tilt kettles are emptied by a spigot and drain on the bottom. Heat is controlled by regulating the steam flow or by adjusting the thermostat. 33 Cooking Equipment Steam-Jacketed Kettles Slide 34 Ideal for cooking foods rapidly and with minimum loss of nutrients and flavor. Pressure Steamers: cooks foods under a pressure of: 15 pounds per square inch (1.05 kg/cm) in high-pressure steamers 4-6 pounds per square inch (0.28-0.42 kg/cm) in low-pressure steamers Door cannot be opened until the pressure returns to zero 34 Cooking Equipment Steam Cookers Slide 35 Pressure-less Steamers or Convection Steamers This type does not operate under pressure. Jets of steam are directed at the food. This speeds the heat transfer. Door can be opened any time during cooking. 35 Cooking Equipment Steam Cookers Slide 36 Bench Type Mixers Range in capacity from 5 to 20 quarts. Floor Mixers Available as large as 140 quarts. Adaptor rings enable several bowl sizes to be used on one machine. Most mixers have three operating speeds. 36 Processing Equipment Mixers Slide 37 Agitator Attachments The paddle is a flat blade used for general mixing. The wire whip is used for such tasks as beating. The dough arm is used for mixing and kneading yeast dough. 37 Processing Equipment Mixers Slide 38 Also known as the Buffalo Chopper Used for general food chopping. Variety of attachments makes it a versatile tool. 38 Processing Equipment Food Chopper Slide 39 Food Grinder Used mostly for grinding meats. Other moist foods may be ground also. Food is forced through a feed tube into a screw. This pushes the food through holes in a plate. At this point it is cut by a rotating blade. The size of the plates holes regulates the fineness of the grind. 39 Processing Equipment Attachments for Mixers and Food Choppers Slide 40 Slicer/Shredder Consists of a hopper and a lever that feeds the food onto a rotating disk or plate. The plate cuts or shreds the food and into a receiving container. Slicing plate may be adjusted to cut various thicknesses. 40 Processing Equipment Attachments for Mixers and Food Choppers Slide 41 Dicer Attachment forces foods through a grid-type blade that cuts them into perfect dice. Blades of different sizes may be used. 41 Processing Equipment Attachments for Mixers and Food Choppers Slide 42 Slices foods more evenly and uniformly than can be done by hand. Blades set at an angle. Slices fall away from these blades. 42 Processing Equipment Slicer Slide 43 Used to chop or pure foods. To mix or emulsify. They can also slice, shred, and julienne foods. 43 Processing Equipment Food Processer Slide 44 Used to mix, pure, and emulsify liquids. Also used to prepare certain drinks. 44 Processing Equipment Blender Slide 45 Chamber vacuum packer: machine pulls the air from a specially designed plastic bag containing food item and seals the bag. 45 Processing Equipment Sous Vide Equipment Slide 46 Immersion Circulator Has a heating element, a pump that constantly circulates the water, and a temperature control. It is used to heat the water in a hot-water bath to a steady temperature within a fraction of a degree. 46 Processing Equipment Sous Vide Equipment Slide 47 Designed to hold foods above 135F (57C) in order to prevent the growth of bacteria that can cause disease. 47 Holding and Storage Equipment Steam Table Slide 48 The refrigerator (known in the trade as the cooler or the box) guards against spoilage and bacterial growth by keeping foods cold, usually, below 41F (5C). The walk-in is a room-size refrigerator with built-in shelves on the walls. The reach-in is a standard upright refrigerator that does not have freezer unit. 48 Holding and Storage Equipment Cold Food Storage Equipment Slide 49 The freezer stores foods purchased in frozen form; used to hold foods for longer times. The walk-in is a room-size freezer with built-in shelves on the walls. The reach-in is a standard upright freezer. 49 Holding and Storage Equipment Cold Food Storage Equipment
