Safe energy-saving freshness-preservation storehouse and freshness preservation method thereof

Abstract

The invention discloses a safe energy-saving freshness-preservation storehouse and a freshness preservation method thereof and belongs to the technical field of storage freshness preservation. The storehouse disclosed by the invention comprises a storehouse main body defined by a roof and a storehouse wall; a cooling device is arranged in the storehouse and comprises a water spraying pipe arranged above the storehouse wall; the water inlet of the water spraying pipe is connected with a water pump and a cold water source; a valve is arranged on the water pipe; a drainage tank is arranged below the water spraying pipe; the water outlet of the drainage tank is communicated with the cold water source; the bottom surface of the drainage tank is an oblique surface inclining toward the cold water source; the lower part of the water spraying pipe is provided with a water outlet hole; and the water spraying pipe is provided with a plastic film which droops into the drainage tank along the wall surface. In the freshness preservation method disclosed by the invention, the cooling device is adopted, and a water pump pumps cold water to the water spraying pipe to spray water; the water flows downward from the inner wall of the plastic film to form a water screen, and flows back to the cold water source from the drainage tank; and the indoor temperature is reduced through water circulation. According to the invention, the indoor temperature is kept at about 6 DEG C, and the low-temperature freshness preservation and safe operation of the storehouse are realized at relatively low cost.

Description

technical field [0001] The invention relates to a fresh-keeping warehouse and a fresh-keeping method, and belongs to the technical field of storage and fresh-keeping. Background technique [0002] At present, the storage of vegetables, fruits, seafood, grains, etc. is mostly stored in warehouses with low temperature. Especially in summer or in hot southern regions, many vegetables and fruits are difficult to store. The warehouses are either in cold caves, and the development cost is high. Either install an air conditioner, which consumes a lot of electricity, which is expensive and unsafe. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a safe and energy-saving fresh-keeping warehouse and a warehouse fresh-keeping method, which utilizes the circulation of cold water such as groundwater and adopts simple and inexpensive means to achieve low-temperature fresh-keeping of the warehouse, wh...
