Canteen cold storage is an indispensable part of the hotel and catering industry, which can extend the storage time of food. Generally speaking, the warehouse of canteen cold storage consists of two parts: the cold storage with a storage temperature of 0-5°C is mainly used for refrigerating and preserving fruits, vegetables, eggs, milk, cooked food, etc.; the freezer with a temperature of -18~-10℃ is mainly used for freezing and preserving meat, aquatic products, quick-frozen pastries, butter, etc. in food ingredients. Therefore, many hotels, restaurants, and canteens gradually choose to assemble refrigerated cold storage or dual-temperature cold storage. So what are the special needs for canteen cold storage in planning and installation?
1. Refrigeration and freezing ratio of cold storage
Different units have different canteen cold storage application requirements, and the division ratio of refrigerated and frozen warehouses is also different. According to the estimation of different storage product quantities during peak periods (such as summer), the proportion of refrigeration and freezing can be better divided. If the refrigerated and frozen warehouses are not adjacent, the use of the warehouse can be more objectively determined in combination with different storage volume requirements.
2. Equipment selection of canteen cold storage
The equipment selection of refrigeration units is the core of cold storage engineering, which largely determines the operation efficiency of cold storage. The cold storage and freezer of the canteen dual-temperature cold storage are better equipped with refrigeration systems, so that they can better play the role of refrigeration and preservation, and can more conveniently adjust the operation of the cold storage according to actual needs. When there is no need to store fruits and vegetables in the canteen in winter, the cold storage can be closed alone to save operating costs. However, for micro dual-temperature cold storage (such as the situation where preservation only accounts for a small part), it is also feasible to share a set of refrigeration units in the equipment selection of units.
Other equipment equipment of canteen cold storage In addition to the equipment selection of canteen cold storage, other equipment such as the selection of cold storage plate thickness, the selection of brands such as cold air machine expansion valve, and the selection of other supporting equipment also need to be comprehensively targeted according to the actual situation of the warehouse, customer cost budget, etc. Considering that the canteen cold storage must frequently store and retrieve goods to ensure sufficient food supply, in order to reduce the impact of the temperature outside the warehouse on the temperature stability inside the warehouse after opening the door, it is generally recommended that customers can appropriately use thermal insulation curtains or air curtains on the cold storage door. If the canteen cold storage is large and forklifts and trolleys are required for loading and unloading, it is recommended to make a separate waterproof and air-tight insulation + concrete on the ground or add a layer of embossed aluminum plate on the ground insulation board, so as to extend the operating life of the cold storage. In addition, because the canteen cold storage is mostly installed near the canteen, it is often prone to accumulation, pests and diseases, and debris plague, so the canteen cold storage manager must clean and disinfect regularly.
