Simple construction of cold chain storage system in leisure agriculture

Cold chain is the high-end of the whole logistics industry, and there are many kinds of different cold chain storage systems corresponding to different construction and operation costs. Here,cold chain we introduce the cold storage cold storage system for fruits in leisure orchards as an example.

Leisure fruit from sorting, storage, processing, packaging to testing production lines, involving more links. And the basic links of an effective cold chain mainly include picking and cooling (pre-cooling treatment),cold warehouse refrigerated storage, refrigerated transportation, refrigerated distribution and sales.

Fruit cold storage is mainly used for freezing processing and cold storage of fruits. Therefore, fruit cold storage requires artificial refrigeration to maintain a certain temperature. Generally speaking, fruit cold storage adopts refrigerator refrigeration, using liquid with very low vaporization temperature (such as ammonia or Freon) as coolant, evaporating under low-pressure and mechanically-controlled conditions, absorbing the heat inside the storage reservoir, so as to achieve the purpose of cooling and cooling. The most commonly used is the compression type cold storage machine, which is mainly composed of compressor, condenser and evaporation tube.

The main types of fruit cold storage are civil engineering fruit cold storage, combined plate fruit cold storage and soil-covered fruit cold storage.

1. Civil engineering fruit cold storage:

Civil engineering fruit cold storage is currently constructed more a kind of cold storage, can be built into a single layer or multi-storey. The main body of the building is generally reinforced concrete frame structure or brick and concrete structure. The enclosure structure of civil cold storage belongs to heavy structure, heat degeneration, outdoor air temperature fluctuation and maintenance structure of the external surface of the solar radiation caused by day and night temperature fluctuations in the maintenance structure of the attenuation of the larger, so the enclosure structure of the internal surface temperature fluctuation is small, the library temperature is easy to be stabilized.

2. Combined board-type fruit cold storage:

Combination plate type fruit cold storage is a single layer form of cold storage, library plate using steel frame lightweight prefabricated heat insulation board assembly structure, load-bearing components are made of thin-walled steel. The inner and outer panels of the library board are colored steel (base material is galvanized steel), the inner and outer panels of the library board are colored steel (base material is galvanized steel), and the core material of the library board is foamed rigid polyurethane or pasted polystyrene foam board. As all the components, except the ground, are prefabricated in sets in specialized factories according to uniform standards and assembled on site, the construction progress is fast and the construction cycle is short.

3. Soil-covered fruit cold storage:

Soil-covered fruit cold storage, also known as soil kiln cold storage, cave body is mostly arch-shaped structure, there is a single cave body type and continuous arch form. Generally for masonry masonry, and a certain thickness of loess cover as a heat insulation layer. Used for low-temperature storage of soil-covered cold storage, the foundation of the cave body should be in the sandstone layer or bedrock that is not easy to freeze and expand. Because it has the advantages of local conditions, local materials, simple construction, low cost, strong and durable, etc., it has been greatly developed in the northwest of China.

The cold chain storage system required for different regions, different terrains, different climates and different costs are different. Therefore, we must choose the suitable cold chain storage system according to the actual situation of our own park, so as to truly realize the high-yield, high-efficiency, low-consumption, non-polluting modern leisure agriculture park, which integrates the comprehensive development of agriculture, production and operation, and sightseeing experience and other functions in one.
