The price difference between fruits and vegetables is big. Combining the reality of decentralized production of rural households in China, research and development of new technologies for storage and preservation of agricultural products, taking into account the current economic characteristics, focuses on the introduction of two more economical cold storage facilities, which are characterized by low investment, quick results, and investment value. First, miniature high temperature cold storage The library houses an area of ​​15 square meters to 20 square meters for general civilian houses and warehouses, 5 tons to 7 tons of fruits and vegetables, and an investment of about 30,000 yuan. This kind of fresh-keeping library is based on the general housing, adding a certain thickness of insulation layer, setting up a refrigeration system, doing the door insulation treatment, the internal cooling fan is hanging, can increase the storage capacity, the refrigeration unit is located outside the library, Because of the small size, the machine room is not needed, and the refrigeration unit is working intermittently, so it consumes less power and is welcomed by users. Preservation principle: The method of reducing the temperature (-1 °C - 15 °C) inhibits the breathing of fruits and vegetables. The cooling system is RMB 19,500 and the library is rebuilt. The total investment is no more than RMB 30,000. Second, micro-modified air conditioning cold storage Air-conditioned storage is currently more advanced domestic and international fruit and vegetable preservation facilities. It can not only adjust the temperature and humidity in the library, but also control the content of oxygen, carbon dioxide and other gases in the library, so that the fruits and vegetables in the library are in dormant state, and still maintain the original quality after leaving the library. 1. Prolonging the storage period of fruits and vegetables is generally 0.5 times to l times longer than ordinary cold storage. When it is stored at the most expensive price, it is sold on the market and the highest profit can be obtained. 2. Keep fruits and vegetables fresh and brittle. Fruits and vegetables after delivery, the water, vitamin C content, sugar, acidity, hardness, color, weight can reach the storage requirements. Crispy fruit, green vegetables, and new picking is almost the same, can provide the market with high-quality fruits and vegetables. 3. Can inhibit the occurrence of diseases and insect pests of fruits and vegetables, so that the weight loss of fruits and vegetables and the loss of pests and diseases to a minimum. 4. The swing period of fruit and vegetable delivery can be extended to 21 days to 28 days, and the swing of the ordinary refrigerator after the storage of fruits and vegetables can only be maintained for 7 days or so. The so-called modified atmosphere preservation is through the gas regulation method to achieve the effect of preservation. Gas regulation reduces the concentration of oxygen in the air from 21% to 3%. 5%, that is, on the basis of high-temperature cold storage, plus a set of air-conditioning system, the use of temperature and control the oxygen content of the two aspects of joint action, in order to achieve inhibition of post-harvest breathing of fruits and vegetables. 15-20 square meters warehouse, storage capacity of 5 tons -7 tons, investment: refrigeration system: 19,500 yuan, air conditioning system: 27,400 yuan. The above two types of cold storage are designed for investors who do not have large capital investment. They have the following characteristics: (1) Wide application scope: It is suitable for storage and preservation of various fruits, vegetables, flowers and nursery stocks in South and North China.

(2) Long shelf life and high economic benefits. For example, if the grapes are kept fresh for 7 months, apples are 6 months old and after 7 months, the quality is fresh and the total loss is less than 5%. The price of a typical grape is only RMB 1.5/kg, but it can be stored up to RMB 6/kg before and after the Spring Festival. One-time investment into a cold storage, the service life of up to 30 years, the economic benefits are very significant. Two years of investment, the year bear fruit.
(3) The operation technology is simple and easy to maintain. Refrigeration equipment, like household refrigerators, automatically starts up and shuts down without special supervision. The supporting technology is also very simple.
Cold Storage and Preservation of Fruits and Vegetables
"Micro cold storage and supporting storage and preservation technology" is a storage and preservation technology with Chinese characteristics. It is an ideal project for large numbers of farmers and agricultural product distribution units to invest in entrepreneurship and develop their wealth.
