1. Baking equipment
Baking equipment mainly refers to the oven, which is the key equipment for baking food production. After the blank molding can be sent to the oven heating, so that products mature, stereotypes, and has a certain color, can fully display the flavor of a variety of pastries.
(1) the type and style of the oven a lot, there is no uniform specifications and models, according to the heat source can be divided into electric oven and gas oven; according to the transmission can be divided into bottom fixed oven and bottom rotary oven two; Type can be divided into cabinet oven and channel oven. In addition, from the level of the oven points can be divided into single, double, three-tier oven.
Electric oven: electric oven is a general term for a class of ovens with electric energy as heat source. General electric oven structure is relatively simple, by the shell, electric wire (or infrared tube), thermal control switch, furnace temperature indicator and other components. Advanced electric oven can be on the next fire were adjusted, with spray steam, timing, alarm and other special features. Its working principle, mainly through the energy conversion of infrared radiation heat, the furnace heat of hot air convection and the furnace metal plate heat conduction way, so that products mature color. Electric oven is very easy to use, adaptable, and in use does not produce waste gas and toxic substances, clean and sanitary products.
Gas Oven: Gas Oven is a gas-based oven, usually single-layer structure, the bottom and both sides of the burning grill, automatic ignition and temperature adjustment function, the furnace temperature up to 300 ° C. Its working principle is the use of gas burning radiant heat, the furnace air convection heat and furnace metal conduction heat conduction mode, so that products mature color. This kind of gas oven has the advantages of quick heating, easy temperature control and low production cost, but the hygienic cleaning of this oven is more difficult.
(2) baking is a technically strong work, the operator must carefully understand and master all the characteristics and performance of the use of the oven, although the production of West Point more types of ovens, but the basic operation is roughly the same.
① the new oven should be read before using the instructions to avoid improper use of the accident.
② food baking oven must be preheated, until the temperature reaches the process requirements before baking.
③ After the temperature is determined, according to a certain process of food requirements reasonable choice baking time.
④ in the baking process, to check the temperature at any time and the appearance of the product changes, timely temperature adjustment.
⑤ After using the oven should immediately turn off the power, the temperature drops after the residue in the dirt to clean up.
(3) maintenance of baking equipment: pay attention to the maintenance of equipment, not only can extend the life of equipment, to maintain the normal operation of equipment, but also the stability of product quality is of great significance. Baking equipment maintenance mainly in the following points:
① often keep the oven clean, clean water should not be used to prevent electric shock, it is best to use kitchen cleaning agent scrub, but the lining of the aluminum material can not use the cleaning agent scrub, but not with a blunt shovel scraping.
② keep the barbecue clean, clean the barbecue to dry, do not put the wet barbecue directly into the oven.
③ long-term use of the oven should be inside and outside the scrub, the plastic cover with a good place in the ventilated and dry place.
2. Food machinery and equipment
West Point Machinery is an important equipment for West Point production. It not only reduces the labor intensity of the producers, stabilizes the product quality, but also helps to improve the labor productivity and facilitate the large-scale production.
(1) the type of commonly used machinery
① special mixer: special mixer structure mainly by the rack, motor, gearbox, lifting start device, stainless steel barrels, stirrer and other components. There are three pairs of gears that match each other in the oil-immersed gearbox at the upper part of the rack, and their center distances are equal, but the ratio of the gears is different. Three different rotational speeds are obtained when the handle is adjusted. Its use is mainly to stir the eggs, butter and make dough.
② powerful universal mixer: powerful universal mixer with slices, crushing, kneading, whipping and other functions, is kneading dough, making bread one of the main machinery, it is characterized by many features, the use of a wide range. The construction of the powerful universal mixer is basically the same as that of the special mixer, but the upper part of the fuselage is used to install the cavities of various processing halves. Vessel capacity of up to 20 liters or more, with three variable speed function.
③ pressing machine: pressing machine is the body frame, motor, conveyor belt, shaft and other components and components. The function of the pressing machine is to press the kneaded dough through the gap between the pressure roller, pressed into the required thickness of leather for further processing.
④ split machine: split machine structure is more complex, there are various types, the main purpose is to the initial fermentation of the dough evenly divided, and made a certain shape. Splitter is characterized by fast segmentation, accurate weight, forming specifications.
⑤ ice cream machine is composed of fuselage frame, motor, refrigeration device, mixing bucket and timer components. Ice cream machine models a lot, the general mixing bucket can produce 3 to 5 liters of ice cream.
(2) the use and maintenance of machinery and equipment
① Before using the equipment to understand the mechanical properties of equipment, working principle and operating procedures, in strict accordance with the procedures. Under normal circumstances have to test machine, check the operation is normal.
② mechanical equipment can not be overloaded, should try to avoid a long time non-stop operation.
③ gearbox equipment should be added in time to keep the oil, to maintain a certain amount of oil to reduce friction, to avoid gear wear.
④ The equipment can not be forced to move the shift handle during the operation, change the speed, otherwise it will damage the transmission parts of the transmission.
⑤ to the regular parts, vulnerable parts of the motor drive maintenance inspection.
⑥ often keep the mechanical equipment clean, clean the outside of the machine can be used to scrub the weak alkaline warm water, cleaning to disconnect the power and to prevent the motor damp.
⑦ equipment operation process found or hear abnormal sound should immediately stop checking, troubleshooting and then continue to operate.
⑧ equipment do not mess up debris, so as not to fall into the mechanical damage to the equipment.
3. Temperature control equipment
Value of temperature equipment is the production of West Point, bread indispensable equipment. Mainly used for raw materials and food fermentation, refrigeration and freezing, commonly used in fermentation tanks, refrigerators, freezers and so on.
(1) common types
① fermentation tank: a lot of fermentation tank model, the size is not the same. The box is made of stainless steel, made of sealed frame, movable door, stainless steel tube bracket, power control switch, sink and temperature, humidity regulator and other components. The working principle of the fermentation tank is to bake the electric wire to heat the water in the tank, so that the dough in a certain temperature and humidity under the full fermentation, expansion. Fermented bread, the general first to adjust the fermentation tank to the ideal temperature and humidity before fermentation. Fermentation tank in the use of water tank can not be dry dry, otherwise the equipment will be seriously damaged. The fermentation tank should always keep inside and outside clean, the sink should always use cleaning agent for cleaning.
② refrigerator: refrigerator is a modern West Point production of the main equipment, according to the structure of a direct cooling and air-cooled two, according to the use of insurance and refrigerated refrigerator refrigerator, no matter what kind of refrigerators are by the refrigerator, Sealed insulation shell, door, rubber seal, removable shelves and temperature regulator and other components. Air-cooled refrigerator from frost, easy to clean, etc., the refrigerator temperature is lower than the direct cooling. Fresh-keeping refrigerators are usually used to store mature food and food raw materials, low-temperature refrigerators are generally used to store frozen raw materials and mature food.
(2) the use and maintenance of refrigerators
Refrigerator should be placed in the air circulation, the box around at least 10-15cm above the space, so that ventilation cooling. The contents of the refrigerator should not be stored too much, when the raw and cooked to separate, stacked food to leave gaps in order to keep air-conditioned. Food cool before you can put the refrigerator, to minimize the number of refrigerator door switch. Close the door must be closed, so that internal and external isolation, keep the box low temperature state. In addition to the refrigerator in the use of the process, should also do routine maintenance work.
① to timely removal of the evaporator on the cream, frost thickness of 4-6mm when you need to defrost. Defrosting to disconnect the power, the food stored in the refrigerator out, so that the frost automatically melt.
② refrigerator cooling system pipe is very long, some tube diameter is only 1.2mm. Disassembly or handling accidentally collision, can cause damage to the pipeline, cracking, so that the refrigerant leak or make the electrical system failure. Refrigeration is not up to the requirements of refrigeration are mostly caused by refrigeration leakage, so often check the refrigerator pipe, such as the problem asked the professional staff to carry out maintenance checks.
③ the refrigerator in the operation should not be cut off the power, which will make the compressor serious overload, resulting in damage to the pump pump and drive motor damage.
④ when the refrigerator to cut off the power, remove the refrigerator food, melt cream layer, and the inside and outside the refrigerator scrub clean, dry after the frost door open slightly, with a plastic cover is good, placed in a ventilated and dry place.
4. All kinds of cases
Also known as the case board, it is the production of snacks, bread table, due to the different materials of the case, there are four common: chicken wood case, marble case, stainless steel case and plastic case.
Wood case texture soft, yeast products and more use of such cases.
Marble case surface smooth, smooth, good heat dissipation, strong anti-corrosion, sugar is still a good living equipment.
Stainless steel case nice, clean and sanitary, smooth and bright, good heat transfer performance, is the major hotels using more workstations.
Plastic case, the texture is soft, corrosion resistance, easy to damage, processing and production of various products are more appropriate, its quality is better than wood case board.
In addition, all kinds of stoves and other West Point is also commonly used equipment.
