Combination of cold storage is expected in the coming years will continue the development of large-scale conventional refrigerator generally use ammonia as a refrigerant in centralized refrigeration systems, cooling equipment, mostly pipes, system complexity vegetable cold storage, automated control difficult. Some small refrigerator low temperature generally used as the refrigerant Freon distributed or centralized refrigeration system. In regard to the construction of civil engineering construction of cold ones cold vegetables, generally low level of automation. In recent years, a combination of an increase in the cost of cold storage, cold storage automation vegetables also increased slightly. Various fruits, vegetables, vegetable base in the main producing areas and the outskirts of cities, such as Shanghai, Jiangsu, Zhejiang and Hubei, Henan and other places, it is important shipping port and other relatively large demand for cold storage. And with the development of agricultural industrialization, promote the processing of agricultural products vegetable cold storage maintenance, finishing and refrigerated food and other related industries developed rapidly. While cold-tonnage, size, quality and degree of modernization have become increasingly demanding. Shanxi Lung Preservation Technology Development Co., Ltd. was established in 2002, Shanxi Academy of Agricultural Sciences, Institute of Science and Technology under the storage and preservation of agricultural enterprises, but also the National Agricultural Science and Technology Park (Taiyuan) enterprises in the park. The company specializes in all types of fruit and vegetable preservation library, pre-cold storage, wholesale and retail business cold storage, cold storage design, construction, refrigeration equipment, as well as fruit and vegetable storage technical advice, guidance and other after-sales service. A variety of cold storage temperature requirements and uses are what frozen library: storage temperature generally below -30 degrees mainly used for frozen foods, such as frozen dumplings. Frozen vegetables, require tender quickly freeze food in a limited time. Low base; temperature is generally -22--25 degree is mainly used for storage temperature at -22--25 degrees pantry. Only at this temperature, the food will not spoil. Features low temperature libraries are: irregular food in the refrigerator gradually, over time, to tender this time there are no special requirements for the storage temperature, cold storage temperature reaches 25 degrees, the temperature After cooling library stability, cold storage temperature requirements are very stringent. Shanxi Lung Preservation Technology Development Co., Ltd. specializes in all types of fruit and vegetable preservation library, pre-cold storage, cold storage, wholesale and retail business refrigerator design, construction, refrigeration equipment, as well as fruit and vegetable storage technical advice, guidance and other after-sales service. Construction of cold storage of vegetables, Shanxi Lung preservation (certified), Xiaodian vegetables cold preservation technology provided by the Shanxi Lung Development Co., Ltd. Shanxi Lung Preservation Technology Development Co., Ltd. (www.sxltbx.com) is Taiyuan, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
