Rice drying equipment

Abstract

The invention belongs to the technical field of rice processing, and particularly discloses rice drying equipment. The rice drying equipment comprises a shell body, rotary tables and rotary shafts vertically arranged. The rotary shafts stretch into the shell body and are provided with a plurality of the rotary tables connected through one-way bearings. Each hopper is arranged between the adjacentrotary tables, wherein the hoppers are rotatably connected to the rotary shafts. Through slots are formed in the rotary shafts in the axial direction, wherein each through slot is divided into a firstsection, a second section and a third section from the bottom to the top. The diameter of the second section is less than the diameter of the first and the third sections. Openings are formed in theside walls of the rotary shafts, wherein each opening is connected with the second section, and air inlet one-way valves are arranged in the openings. Upswept edges are arranged on the peripheries ofthe rotary tables. The hoppers are inverted cones and each diameter of the upper diameter opening is larger than the diameter of the rotary tables. Screens abuting against the upper diameter opening are arranged on the inner walls of the shell body, wherein each bore diameter of the screens is one to three millimeters. Notches are alternately formed at the lower diameter openings of the hoppers. An air heater is arranged at the bottom of the shell body and communicates with the rotary shafts through a conduit. Discharge holes are formed in the bottom of the shell body. The rice drying equipment can make the rice intermittent heating and uniform drying.

Description

technical field [0001] The invention belongs to the technical field of rice processing and specifically discloses rice drying equipment. Background technique [0002] In order to increase the shelf life of rice, it is necessary to reduce the moisture content of rice. The current practice is to reduce the moisture content of rice by drying and drying. [0003] It takes a long time to dehydrate rice by drying, which is not conducive to mass production, and the water removal is uneven. As for the drying method, although it can be dried in large quantities at present, and the work efficiency is relatively high, most of the existing dryers use a heat source to directly heat the container containing the rice, and the heating raw materials are mainly coal, Diesel oil, kerosene, etc., will produce a lot of pollution during the drying process; at the same time, the heating source will cause the local temperature of the container to be too high, resulting in localized dew condensatio...

[0003] It takes a long time to dehydrate rice by air drying, which is not conducive to mass production, and the water removal is uneven

As for the drying method, although it can be dried in large quantities at present, and the work efficiency is relatively high, most of the existing dryers use a heat source to directly heat the container containing the rice, and the heating raw materials are mainly coal, Diesel oil, kerosene, etc., will produce a lot of pollution during the drying process; at the same time, the heating source will cause the local temperature of the container to be too high, resulting in localized dew condensation on the rice there, and even a large number of broken grains in the rice. thereby reducing the quality of rice
