Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method that can reduce the breakage rate of rice production and store rice with fan cooling and storage. It has the advantages of ensuring the integrity of rice grains and high drying efficiency, and solves the problem of excessive heating and drying speed or improper parameter selection. Bursts occur, resulting in microscopic cracks on the surface of the grains, which directly affects the broken rice rate during rice milling, thereby affecting the rice yield of rice

Embodiment 1

[0021] A kind of method that can reduce the breakage rate of rice production fan cooling and storage paddy, is characterized in that, has the following steps:

[0022] (1) Rice processing, after the rice is harvested, the rice is initially screened to filter out the dust, residual leaves and insect limbs mixed in the rice, and the empty shells and residual grains in the rice are screened out, and finally transported to the Inside the storage tank, the bottom of the storage tank is fixed with a support tripod, and there are three support tripods that are evenly distributed on the outer surface of the bottom arc-shaped cover, and the support tripods are fixedly connected by steel connecting columns;

[0023] (2) The rice is cooled and dried, and the interior of the storage tank is fixed with a ventilation pipe, and the extension branch pipe is fixedly installed on the ventilation pipe. The outer surface of the extension branch pipe is provided with a ventilation hole, and the ins...

Abstract

The invention relates to the technical field of grain storage, and discloses a method for reserving unhulled rice through fan cooling and with a function of being capable of decreasing the crashed rate of rice production. The method comprises the following processes of (1) unhulled rice treatment, (2) unhulled rice cooling and drying, and (3) air circulation filtration. According to the method forreserving the unhulled rice through fan cooling and with the function of being capable of decreasing the crashed rate of rice production, by arranging an extending branch pipe, the unhulled rice in equipment can be fully subjected to overall cooling and air drying through a fan; filtering screening nets are fixedly mounted in ventilating holes, the hole diameter of the filtering screening nets isless than the diameter of the unhulled rice, and thus the phenomenon that the unhulled rice enters the ventilating holes and consequently the ventilating holes are blocked is avoided; by arranging adrying air pipe, air dryness in the equipment can be maintained, and storage of the unhulled rice is facilitated; and air exchanging openings are formed in the outer surface of a filtering box, a dustfiltering net is fixedly mounted in the filtering box, moisture in a storage tank can be exhausted by the air exchanging openings, and residual dust in a filtering pipe can be filtered by the filtering net.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a method for reducing the rice production breakage rate and fan cooling and storing rice. Background technique [0002] Paddy is a kind of heat-sensitive crop. If the drying speed is too fast or the parameters are improperly selected, it is easy to cause bursting. The so-called "cracking" means that after the rice is dried or cooled, microscopic cracks appear on the surface of the grains, which directly affects the broken rice rate of the rice during rice milling. , thereby affecting the rice yield of rice, that is, affecting its yield and economic value, so the national standard stipulates that the increased value of the bursting rate should not exceed 3%. Secondly, the structure of rice is different from other food crops. Rice grains are composed of a hard shell and rice grains. The shell protects the rice, so rice is easier to preserve than rice. Surface transfer effect...
