Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain and oil production, in particular to a drying box for grain and oil production. Background Art
[0002] Drying is a process of removing liquid from solid materials or products. Grain and oil is a general term for grains such as cereals and legumes, oilseeds, and their processed finished and semi-finished products, which is a general term for the main foods of humans. The purpose of grain and oil drying treatment is mainly to remove the moisture in grains to reach an appropriate moisture content to maintain the quality of grains and facilitate storage. The drying treatment of cereals and legumes can prevent them from mildewing, deteriorating, and generating peculiar smells during storage, and at the same time, it can also reduce the content of bacteria and molds. In addition, the drying treatment can also improve the taste and nutritional value of cereals and legumes, which is beneficial to the processing and utilization of cereals and legumes.
[0003] Most of the existing drying boxes for grain and oil production have a simple structure. They simply introduce heating gas into the treatment container, resulting in insufficient contact between the materials to be dried and the heating gas, seriously affecting the drying quality. Moreover, impurities or fragments in the materials cannot be screened out during the drying process, affecting the subsequent production quality of the materials.
[0004] Therefore, a drying box for grain and oil production is needed to overcome the above defects. Content of the Utility Model
[0005] I. Technical Problems to be Solved

[0007] II. Technical Solutions
[0008] To solve the above technical problems, the technical solution provided by the utility model is: a drying box for grain and oil production, including a drying box body. The drying box body is horizontally placed and a box door is installed at one end. An inlet chute is installed at the top of the drying box body;
[0009] A first air duct and a second air duct penetrate through a side wall of the drying box body far away from the box door. The first air duct is rotatably installed at the center of the side wall of the drying box body, and the second air duct is fixedly installed at the top of the side wall of the drying box body. A plurality of air outlet openings are provided on the outer wall of the part of the first air duct located inside the drying box body. A spiral stirring frame is installed outside the first air duct. An arc-shaped mesh plate is installed at the bottom inside the drying box body. A discharge port is installed at the lower side of the drying box body. A collection box is installed at the lower side of the drying box body and outside the discharge port.
[0010] As an improvement, a first gear is sleeved on the outer side of one end of the first air duct located outside the drying box body, a motor is installed on the outer wall of the drying box body away from the box door, and a second gear engaged with the first gear is installed at the end of the motor shaft.
[0011] As an improvement,
[0012] As an improvement, the arc-shaped mesh plate does not contact the inner wall of the drying box body.
[0013] As an improvement, the edge of the spiral stirring frame is made of rubber and contacts the inner wall of the arc-shaped mesh plate.

[0016] III. Beneficial effects
[0017] The advantages of the present utility model compared with the prior art are as follows:
[0018] 1. The grain and oil materials are on the upper side of the arc-shaped mesh plate inside the drying box body, which can ensure ventilation on the lower side of the grain and oil materials. Through the reciprocating rotation of the spiral stirring frame, the grain and oil materials are stirred. During the stirring process, the first air duct sends hot air to the middle of the grain and oil materials through multiple air supply pipes, ensuring sufficient contact between the materials and the heating gas.
[0019] 2. During the stirring process of the grain and oil materials, impurities and fragments in the grain and oil materials are screened out through the arc-shaped mesh plate and fall into the collection box for collection, improving the quality of the subsequent production of the materials.
