Unhusked rice dryer

Abstract

The invention relates to the technical field of agricultural mechanical equipment, in particular to an unhusked rice dryer. The unhusked rice dryer comprises a heating barrel, a roller and a drive unit, wherein the heating barrel and the roller are arranged on a rack, and the drive unit drives the roller to rotate. The heating barrel and the roller are arranged coaxially and are in running fit. Abarrel cavity of the heating barrel communicates with a heat source. A feeding opening is arranged at one end of the roller, and a discharging opening is arranged at the other end of the roller. An unhusked rice drying chamber is formed by a clamp cavity between the roller and the barrel wall of the heating barrel. The unhusked rice dryer has the advantages that the unhusked rice dryer is provided, the heating barrel heats unhusked rice in the roller, the unhusked rice repeats turnover action in the drying process, excessive heating is avoided, and it can be guaranteed that drying is achievedsufficiently; and few cracking phenomena of the unhusked rice dryer during later processing happen, the rice breaking rate is low, and few yellowing phenomena happen. In addition, the dryer is simplein structure, the size can be determined according to actual application conditions, and the unhusked rice dryer is suitable for household operation and also suitable for the drying requirement of large farmlands and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, and more specifically relates to a rice dryer. Background technique [0002] Rice, native to China, is one of the world's main food crops. After the rice is mature, it needs to be harvested to obtain rice, and the rice can be stored after being dried. In the prior art, there are two drying methods for paddy as follows: one is the natural sun drying method, that is, the paddy is spread on the drying field, exposed to the sun and manually turned in real time, in order to dry evenly. The disadvantages of this method are: the drying cycle of rice is long, the labor intensity caused by repeated spreading-turning-collecting actions is high, and there are frequent thunderstorms in summer, and the rice that is not collected in time is prone to mildew, and the quality of rice cannot be guaranteed. The second is the rapid drying method, that is, using a dryer to heat the padd...

The disadvantages of this method are: the drying cycle of rice is long, the labor intensity is high due to repeated spreading-turning-collecting actions, and there are frequent thunderstorms in summer, the rice that is not collected in time is prone to mildew, and the quality of rice cannot be guaranteed

The second is the rapid drying method, that is, using a dryer to heat the rice evenly at a higher temperature to complete the drying process. The disadvantage of this method is that due to the tight texture of the rice, the moisture contained in it is difficult to transfer in liquid form.

In addition, the scorching heat on the surface of the rice will lead to strong brittleness and weak toughness on the surface of the rice. When it is processed into rice in the later stage, under the extrusion and friction of rubber rollers and vibrating screens, the rice is easy to crack, resulting in broken pieces. High rice rate
