Rotary rice drying system

Abstract

The invention relates to a rotary rice drying system. The rotary rice drying system is characterized in that a drying roller is horizontally arranged, a left feeding box is arranged on the left side of the drying roller, a hot air inlet pipe is arranged at the top end of the left feeding box, and a drying roller butt joint hole is formed in the right side surface of the left feeding box; a rice feeding pipe is further arranged in the left feeding box, the rice feeding pipe is vertically arranged on the left feeding box, and the lower end of the rice feeding pipe extends into the drying roller;and a cleaning bin door is arranged at the bottom of the left feeding box, a plurality of inclined stirring pieces are arranged on the inner wall of the drying roller, and a supporting frame is arranged at the bottom of the drying roller. The rotary rice drying system has the advantages of being reasonable in design and reliable in performance, so that the heat energy utilization rate is high, the drying is uniform, the material cleaning frequency is less, and the maintenance is convenient.

Description

technical field [0001] The invention belongs to a drying system, in particular to a rice drying system. Background technique [0002] Rice is the main food crop in my country. In recent years, the rice planting area in the northeast reclamation area has expanded rapidly. The rice harvest in the northeast cold region is in early October, and the temperature is around 0°C. The harvest season is tight. Therefore, most rice is harvested by rice combine harvesters. The moisture content of rice is high, and the drying problem after rice harvest has become a very urgent problem. The quality problem after drying is the key to rice drying. Rice drying requires not only high productivity, but also good quality after drying, that is, low bursting rate and good taste. According to data from the United States, the price difference between high-grade rice (broken rice rate is less than 10%) and low-grade rice is about 100 US dollars per ton, and the annual output of rice in my country is...
