Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0030] refer to figure 1 Shown, the present invention provides a kind of grain drying process, comprises the following steps:

[0031] Preliminary filtration, using a screening and impurity removal device to remove heavy gravel impurities in the grain;

[0032] Fine filtration, the grain enters the drying equipment to remove dust and broken shell impurities;

[0033] Grain dispersal, the grain passes through the inside of the drying equipment to disperse the grain evenly and prevent it from forming a grain mass;

[0034] Grain slowing, the slowing process is carried out on the grains, and the slowing process keeps the grains in a non-ventilated...

Abstract

The invention discloses a grain drying process and drying equipment. The process comprises the steps of carrying out primary filtration, fine filtration, grain dispersion, grain tempering, grain drying, grain circulation and grain storage; the drying equipment comprises a drying machine, wherein a supporting base is fixedly installed at the lower end of the drying machine; the drying machine is divided into a tempering homogenizing section, a drying section and a discharging section from top to bottom, and the tempering homogenizing section and the drying section are consistent in height; whengrains are dried, the processes of windless tempering treatment, hot air heating and final tempering discharging are adopted, so that the temperature difference change of the grains is small, and thequality and value of the grains are improved; the height ratio of the tempering homogenizing section to the drying section is set to be 1: 1, so that the overall height of the drying machine can be greatly reduced, and therefore the produced finished product is reduced, and on the premise of ensuring the drying speed, the drying quality is improved.

Description

technical field [0001] The invention relates to the technical field of grain drying, and more specifically relates to a grain drying process and drying equipment. Background technique [0002] At present, when grain is dried, not only high drying rate is required, but also high quality is required. Circulating dryer generally adopts drying-slow drying process. First, the grain is stored for a period of time to evaporate part of the water, and then the grain is kept warm. For a period of time, the moisture inside the grain is diffused to the surface, reducing the moisture gradient inside the grain, and then enters the next drying process. This process can improve grain quality and reduce energy consumption, but adding a slow recovery process in the drying process will inevitably reduce the productivity of the dryer. [0003] The Japanese circulation grain dryer is equipped with a slowing section inside, and the ratio of the slowing section time to the drying time is 5:1 to 8...
