1. What are the selection principles of hotel-specific cookers?
1, hygiene principle? Kitchen equipment should have anti-pollution ability, especially the function of preventing cockroaches, mice and ants from polluting food, so as to ensure the internal quality of the whole kitchen equipment.
2, the principle of fire prevention? The surface of kitchen equipment should have fire-proof ability, and the surface materials of kitchen equipment produced by regular kitchen equipment manufacturers are all incombustible flame retardant materials.
3. The principle of convenience? The operation of the kitchen should have a reasonable process. In the design of kitchen equipment, it is very important to design the arrangement of each part according to the correct process, which is very convenient for future use. Then the height of the cooker and the position of the hanging cabinet directly affect the convenience of use. We should choose kitchen equipment that conforms to ergonomic principles and kitchen operating procedures.
4. The principle of beauty? Kitchen equipment not only requires pleasing appearance and color, but also requires durability, so it requires easy pollution prevention and good cleaning performance.
2. What are the selection criteria for hotel-specific cookers?
Safety, that is, stoves must meet the relevant national standards, and regular products must be purchased in regular shopping malls. For example, according to the requirements of the current effective national standards, the new embedded cooker must have a flameout protection device, and consumers must pay attention to this when purchasing. Because of the special use conditions, the embedded gas stove is more prone to accidental flameout during use, and the flameout protection safety device will play a good role in protection.
High efficiency, that is, the maximum utilization of energy, is directly manifested in ensuring the full combustion of gas. Efficient hotel cookers can not only provide higher temperature and save energy, but also greatly reduce the concentration of carbon monoxide produced by incomplete combustion, thus greatly improving safety. In order to ensure high efficiency, the most critical technology is the design of secondary air intake. At present, all brands have their own brilliant ideas, so we must pay attention to identification and comparison when buying.
Third, how to choose the hotel-specific cooker?
1. Buy products produced by manufacturers with production licenses.
At present, the production of domestic gas cookers in China implements the product production license system. Therefore, when purchasing, we must recognize the production license number, factory name, address and quality certificate marked on the product. It is recommended to buy well-known brands and products with good after-sales service in regular shopping malls or specialty stores.
2. Observe the appearance of hotel cookers.
Some products made of cast iron, steel plate and other materials should be painted evenly, without foaming or falling off. The overall structure of the gas stove should be stable and reliable, the stove surface should be smooth and flat, without obvious warping, and all parts should be installed firmly and reliably without looseness.
Step 3 give it a try
The installation position of the switch knob, nozzle and ignition device of the hotel cooker must be accurate. During ventilation and ignition, the gas should be ignited every time (the flame can be ignited at least ten times, more than ten times). After ignition, the flame should burn all the fire holes within four seconds. When the electronic igniter is used to ignite, the human body will not feel electric shock when touching the metal part of the cooker. When the flame burns, it should be uniform, stable and blue, without yellow fire and red fire.
4. After-sales service
The installation and maintenance of hotel cookers must be carried out by professionals trained by the manufacturer or its designated after-sales service unit and qualified for installation. In addition, there are stoves, pipes, cabinets and so on. It should be checked regularly. It is recommended to clean up the carbon deposits in gas appliance once every six months or so to check whether the gas hoses are aging.
Pay attention to service life. In general, the service life of gas stoves is eight years. If there are faults such as air leakage, water leakage and deterioration of combustion conditions, they should be scrapped in time to eliminate potential safety hazards so as to avoid disaster.
The above is the introduction of the hotel's special cooker. Bian Xiao mainly introduces its selection principles, selection criteria and matters needing attention in selection. Because the hotel kitchen is special, the scale of the hotel and the form of energy use should be considered in general. When choosing, you can learn and understand according to all aspects introduced by Bian Xiao, and then choose a special cooker that is really suitable for the hotel kitchen.
