Rice drying device

Abstract

The invention relates to the technical field of rice drying, and specifically discloses a rice drying device. The rice drying device comprises a first drying box, a second drying box and hot air mechanisms, wherein the upper part of the first drying box is rotatably connected with a first rotary shaft; the first rotary shaft is connected with a motor; a charge hopper is fixedly mounted on the first rotary shaft; the first rotary shaft is connected with a crankshaft through a bevel gear; the other end of the crankshaft is rotatably connected on the lower wall of the first drying box; the side wall of the first drying box is hinged with a plurality of drying plates; the drying plates are equipped with material transfer ends; gaps are formed between the material transfer ends and side walls;the hot air mechanisms are arranged on the side walls which correspond to the material transfer ends; an unloading hole is formed in the bottom of the first drying box; an opening is formed in the upper part of the second drying box; a drying barrel is mounted in the second drying box; a second rotary shaft is arranged on the middle part of the drying barrel; the inner part of the second rotary shaft is hollow, and the second rotary shaft is equipped with an air outlet; the second rotary shaft is connected with a hot air blower; and a pulling rod is hinged between the second rotary shaft and the first rotary shaft. The rice drying device solves the problems such as long rice drying time, low efficiency and uneven drying.

Description

technical field [0001] The invention relates to the technical field of rice drying, and specifically discloses a rice drying device. Background technique [0002] After the rice is harvested, the water content is relatively high, and it needs to be dried before rice milling. Improper drying of rice after harvest will cause the following hazards: 1. Drying high-moisture rice with high temperature and hot air will make the taste of rice worse; 2. Dry rice absorbs water rapidly, and high-moisture rice rapidly discharges water, which will cause grain cracks. Commonly known as "explosive waist". If the waist burst rate is too high, the taste of the rice will deteriorate, and the rice yield will also decrease during rice milling. In addition, if the harvested rice is not dried in time, the grain is prone to germination and mildew to produce aflatoxin, which will cause cancer after human consumption. Therefore, it is meaningful to dry the rice in time after harvesting. [0003]...
