How much does the cold storage cost for 30 square meters?

Seafood is a kind of fresh product that needs low temperature storage, otherwise it is easy to rot and deteriorate at normal temperature.Whether domestic or foreign seafood products are processed, stored and transported strictly, the freshness and flavor of seafood products can be guaranteed before they can be sold to consumers.How much does it cost to build a seafood cold storage?The following are the specific factors affecting the cost of seafood cold storage:
1. Cold storage specification:The size (length, width and height) of seafood cold storage is a very important factor affecting the price of cold storage.For example, a 30 square meter seafood cold storage, based on the conventional height of 3.5 meters, has a total construction capacity of 105 cubic meters,Then the cost of the seafood cold storage is about 50000-70000 (this price is for reference only).
2. Storage board cost:The insulation board of cold storage is also one of the factors affecting the cost of cold storage.According to the grade, the cold storage plate can be divided into three grades: low, medium and high materials, and the corresponding plate thickness is 100 mm, 120 mm and 150 mm. Different grades of plate and thickness will directly affect the insulation effect and service life of the cold storage.
At present, polyurethane and polystyrene are commonly used, polyurethane board is our commonly used, advantages are greater than polystyrene board, but the price is much higher.Polystyrene board is also called foam board. Its advantage is that it is cheap, but it has poor thermal insulation performance. If it has been used for a long time, it is easy to deform. It is generally only suitable for refrigerators above 0 ℃.Therefore, it is recommended to use 120mm thick polyurethane insulation board for seafood cold storage at minus 18 ℃.
3. Unit cost:The difference between seafood cold storage equipment and other cold storage equipment is that the brand and specification of cold storage equipment are determined according to the demand of refrigeration capacity.For example, bizel and GuLun are well-known imported brands, and the cost is relatively higher, so different brands will also affect the cost of cold storage.In general, small seafood cold storage uses fully enclosed compressor, medium-sized seafood cold storage generally selects semi closed compressor, and large-scale seafood cold storage selects semi closed compressor or screw compressor. Therefore, the selection of compressor units is different and the cost is different.
4. Cold storage temperature:The temperature of cold storage is one of the important factors to prolong the fresh-keeping period of seafood. Different refrigerators store different seafood, so the temperature of cold storage is different, for example:The preservation temperature of general seafood aquatic products is - 18 ~ - 23 ℃, but high-end seafood such as tuna and abalone need to be stored at - 55 ℃ or below。Therefore, before building a cold storage, we must know what seafood customers mainly use to store?Are there any special temperature requirements?In order to better determine the best temperature of the cold storage, choose a more suitable cold storage unit.
