The cold storage is a facility for artificially controlling and maintaining a stable low temperature using refrigeration equipment. The basic components are: a refrigeration system; an electric control device; a warehouse with certain thermal insulation properties, and ancillary buildings.
Common types of cold storage: The storage capacity is larger than 1,000 tons for large-scale storage, 100-1,000 tons for the medium-sized library, less than 100 tons for the small library, the most suitable for the production of rural areas 10 to 100 tons of small libraries.
The most suitable freshness preservation temperature for most agricultural products is around 0°C. The minimum temperature for fresh fruits and vegetables is 2°C, which is a high-temperature store; while the preservation temperature for aquatic products and meat is below 18°C, which is a low-temperature storehouse.
It is most suitable to build a small cold storage of 10 tons to 20 tons in rural areas. Small cold storage investment of 2-40000 yuan (not including warehouse civil engineering part), small cold storage unit capacity is small, easy to control, easy access to storage, a product is easy to store full, rapid cooling, temperature stability, low power consumption, degree of automation High, as easy to manage as home air conditioners and refrigerators. Multiple small cold storages can also form a small cold storage group, which can keep more products and varieties. According to the different preservation temperature can achieve any separate control. The flexibility, operability, degree of automation, energy saving effect, and economic effect are better than those of medium and large-scale cold storage. The total investment of the small cold storage group is similar to that of large and medium-sized cold storages of the same scale.
The civil construction and assembly compound cold storage is the most economical application, and it is the preferred form of cold storage in the production area. The 20 tons of new type cold storage built by the Shandong Institute of Fruit Research, and the TZFX??20Q type of civil construction and assembly combined small cold storage capacity of about 110 cubic meters are economical. Over 10,000 yuan of type thermal insulation works, refrigeration engineering (with FGWQ?501 or 502 on-hook) is less than 30,000 yuan, and the total project cost is about 40,000 yuan, excluding the civil construction part of the house. Civil-built houses are ordinary houses with no windows, leaving only door openings. Its walls and covers are brick, brick or brick-concrete structures, as long as it is weatherproof and sturdy, and the construction cost is lower than that of the people's houses. The heat insulation and insulation structure is applied on the inner walls of civil buildings. Insulation Materials. The new air-cooled, high-efficiency and low-noise wall-hanging refrigeration unit used in cold storage is created by the Shandong Guoshu Research Institute and represents the highest level of small cold storage facilities in China. It is also the world's advanced level and is 30% to 50% lower than similar imported equipment configurations.
Some fresh produce storage temperature adjustment:
Most fruits such as apples, pears, grapes, kiwifruit, apricots, plums, cherries, persimmons and other fruits of the northern deciduous fruit have better storage temperatures between 1°C and 1°C.
The suitable temperature of jujube and garlic is between 2°C and 0°C.
Peach fruit suitable temperature at 0 °C ~ 4 °C;
Strawberry 0 °C ~ 1 °C; watermelon 4 °C ~ 6 °C;
About 13 °C banana; citrus 3 °C ~ 6 °C;
Tomatoes, green peppers around 10 °C;
Carabo, cauliflower around 0 °C;
Ginger 12 °C; grain rice 0 °C ~ 10 °C.
The ideal temperature index, different varieties, site conditions, etc. have certain differences, long-term storage, short-term storage, storage early and late have different requirements, generally need to be finalized through the preservation test.
Each of the above temperature reference indicators refers to the temperature of the product or the temperature of the product. In general, the temperature of the product is between the upper and lower limits of the air temperature in the library.
