Grain drying cooler

Abstract

The invention discloses a grain drying cooler, which comprises a first drying cooling system, a second drying cooling system, a centrifugal fan and a condensed water recycling device, wherein the first drying cooling system is used for evaporating and drying moisture in grains and cooling and storing the grains; the second drying cooling system is used for evaporating and drying the moisture in the grains and cooling and storing the grains; the centrifugal fan is used for outputting air quantity; and the condensed water recycling device is used for recycling condensed water. The grain drying cooler disclosed by the invention has the beneficial effects that by adopting uniform-temperature cooling and storage, a drying process can be shortened; energy can be saved; storage temperature of the grains can be regulated; temperature difference is reduced; the grains can be stored safely; cold storage can reduce self breathing of the grains so as to fulfill the aim of loss reduction and storage; proliferation of stored grain insects, mould and microorganisms can be restrained; moisture transfer, delamination and condensation can be prevented or eliminated; peculiar smell in grain stacks can be removed; safety of the grains is ensured; and good quality of the grains is guaranteed.

Description

technical field [0001] The invention belongs to drying and cooling equipment, in particular to a grain drying and cooling machine used for grain drying and cooling storage. Background technique [0002] At present, after the grain is purchased, due to the high moisture content, it needs to be evenly dried before it can be put into storage, which increases the manpower and material resources in the links of turnover, transportation, and drying. [0003] During the long-term storage of grains, due to the radiation of external heat, the grains will heat up and heat up. However, the country advocates low-temperature storage of grains, which can ensure the freshness of grains and long-term storage. The traditional cooling machine has a small air temperature difference and cannot In the case of high temperature outside, the low-temperature air supply is effectively provided, so that the purpose of low-temperature grain storage cannot be effectively realized. [0004] The disadvan...

Problems solved by technology

[0002] At present, after the grain is purchased, due to the high moisture content, it needs to be evenly dried before it can be put into storage, which increases the manpower and material resources in the links of turnover, transportation, and drying.

[0003] During the long-term storage of grains, due to the radiation of external heat, the grains will heat up and heat up. However, the country advocates low-temperature storage of grains, which can ensure the freshness of grains and long-term storage. The traditional cooling machine has a small air temperature difference and cannot Effectively provide low-temperature air supply in the case of high temperature outside, so that the purpose of low-temperature grain storage cannot be effectively achieved

[0004] The disadvantages of the common coolers used for grain cooling in the market are: large unit, high energy consumption, long cooling time, etc., and the common ones used for grain storage in the market are usually only dryers or coolers, which lack the ability to simultaneously dry and cool.
