Modular reversing ventilation drying machine

Abstract

The invention relates to a modular reversing ventilation drying machine, and relates to the technical field of agricultural machines. The machine comprises a drying channel formed by splicing at leasttwo drying chamber modules. Each drying chamber module is formed in the manner that a bottom air flue with the top face opened is hinged to one side of a chamber body with the bottom face provided with a screen. One end of the drying channel is provided with an upper air supply port and a lower air supply port which lead to the corresponding bottom air flue and the upper portion of the corresponding chamber body correspondingly. The bottom face of each bottom air flue and the top face of the corresponding chamber body are provided with air guiding mechanisms distributed at intervals in the air supply direction. The air guiding mechanisms adjacent to the air supply ports are composed of adjustable-angle double-rocker air deflectors, and the air guiding mechanisms away from the air supply ports are composed of adjustable-angle hinge support deflectors. The top face of each chamber body is provided with a box cover capable of being opened, wherein the lower portion of the side face adjacent to the hinged position is provided with unloading doors capable of being opened. According to the modular reversing ventilation drying machine, the phenomenon that bottom materials are excessivelydried while top materials are insufficiently dried is avoided, and the drying quality is guaranteed. Meanwhile, transporting and installing are greatly convenient, and peanuts and other materials poor in mobility are poured and unloaded very conveniently.

Description

technical field [0001] The invention relates to a dryer for peanuts and other agricultural products, in particular to a modular reversing ventilation dryer, which belongs to the technical field of agricultural drying equipment. Background technique [0002] According to the applicant's knowledge, the existing drying equipment suitable for harvesting large-grained, fragile and poorly fluid materials such as peanuts is mainly a fixed-bed ventilation drying equipment, which is composed of a drying box, an air control pipe, and a hot air blower. The following problems generally exist in use: 1) The ventilation direction is single, only from the bottom to the top to ventilate and dry, and the vertical direction of the thicker materials is obviously dried unevenly, and the phenomenon of excessive drying of the bottom materials and insufficient drying of the top materials often occurs. Not only does it affect the quality of the dried material, but it is also prone to mildew and ins...

AI Technical Summary

Problems solved by technology

[0002] According to the applicant's understanding, the existing drying equipment suitable for harvesting large-grained, easily damaged and poorly fluid materials such as peanuts is mainly a fixed-bed ventilation drying equipment, which is composed of a drying box, an air control pipe, and a hot air blower.

The following problems generally exist in use: 1) The ventilation direction is single, only from the bottom to the top to ventilate and dry, and the vertical direction of the thicker materials is obviously dried unevenly, and the phenomenon of excessive drying of the bottom materials and insufficient drying of the top materials often occurs. Not only does it affect the quality of the dried material, but it is also prone to mildew and insects; 2) The uniformity of the wind field distribution is poor, and the material is also dried unevenly in the horizontal direction; 3) It is bulky, not only inconvenient for transportation and installation, but also poor in adaptability; 4) Due to the poor fluidity of materials such as peanuts, unloading is difficult, and complex unloading mechanisms are often required; 5) Heat waste is serious and energy costs are high
