Commercial Kitchen refrigerators, also known as kitchen freezers, are low-temperature storage devices used in the catering industry to store ingredients. Commercial refrigerators refer to refrigerated or frozen freezers that are exclusively used by commercial operation channels such as supermarkets, cold drink stores, frozen goods stores, and hotels and restaurants to store ice cream, beverages, dairy products, quick-frozen foods, and food materials. Because the kitchen refrigerator is used in the back kitchen and needs to be in contact with food and raw materials, it should have the characteristics of wear resistance, acid and alkali resistance, fire prevention, antibacterial, and sanitation. Therefore, kitchen refrigerators are generally made of stainless steel. Kitchen refrigerators are generally divided into desktop, two-door, four-door, six-door, etc. according to the structure and door body. Perfect, items with different storage temperature requirements can be retrieved in different compartment doors, which can reduce the mutual interference of stored items and help reduce air-conditioning leakage.
