Cereal cooling dryer

Abstract

The invention provides a cereal cooling dryer for killing worms in cereals and removing the moisture in the cereals through the high temperature in a drying process. The cereal cooling dryer comprises a casing and a power supply, and the casing is provided with a controller; a first heat exchanger chamber, a second heat exchanger chamber and a circulation loop are arranged in the casing, and the circulation loop is formed by sequentially connecting a first compressor, a four-way valve, a first heat exchanger, a throttling part, a second heat exchanger and a first gas-liquid separator through a pipeline; the first heat exchanger is installed in the first heat exchanger chamber, and a first supply air inlet, a first return air inlet and a first air blower used for ejecting air in the first heat exchanger chamber to a drying room are also installed in the first heat exchanger chamber; the second heat exchanger is installed in the second heat exchanger chamber, and a second supply air inlet, a second return air inlet and a second air blower used for ejecting air in the second heat exchanger chamber to the outside of the drying room are also installed in the second heat exchanger chamber; and the power supply is connected with all electronic parts through a wire, and the controller is electrically connected with all electronic control parts.

Description

technical field [0001] The invention relates to a grain cooling and drying machine. Background technique [0002] As we all know, an appropriate low temperature environment is required during the grain storage process to keep the grain in a dormant state and prevent germination, and at the same time, it can also reduce the respiration of the grain itself and prevent excessive energy consumption of the grain itself. The low temperature is generally maintained at about 10 degrees Celsius. For the above reasons, grain coolers need to be equipped in large warehouses or specialized grain storage bases. The function of the cooler is to cool down the grain heap so that the temperature of the grain heap is not higher than 10 degrees Celsius. The grain cooling machine in the prior art only has cooling function. In actual use, although the temperature of the grain heap can be controlled not to be higher than 10 degrees Celsius, at this temperature, the worms in the grain heap can s...

AI Technical Summary

Problems solved by technology

In actual use, although the temperature of the grain heap can be controlled not to be higher than 10 degrees Celsius, at this temperature, the worms in the grain heap can still survive and their activity is not affected, so the grain cooler in the prior art is in use , the bugs in the grain pile cannot be killed, and the bugs will destroy the grain

In addition, the grain cooler in the prior art does not have a drying function, and cannot remove the moisture in the grain heap, and the grain heap is prone to damp deterioration

In summary, the grain coolers in the prior art have the disadvantages of not being able to kill insects in the grain and not being able to remove moisture from the grain
