Combined Air Dryer

Abstract

The invention relates to a grain storing device, and in particular to a combined type air drying machine. The combined type air drying machine comprises a grain storing section, at least one air drying section, a grain discharging mechanism and an air exhaust mechanism, wherein the grain storing section is arranged above the air drying section, the air drying section is arranged above the grain discharging mechanism, and the air exhaust mechanism is connected with the air drying section and is arranged at the side of the air drying section. The air drying machine has the advantages of good ventilation performance, simple structure, energy saving, convenient grain feeding and discharging, long service life, good drying effect, no need of heating devices, quick moisture reduction speed, simple technological process, delicate structure, convenient assembly, disassembly and transport, good economic and durable performance, easy production in batches, and the like.

Description

technical field [0001] The invention relates to a grain storage device, in particular to a combined air dryer. Background technique [0002] In order to be able to store food safely, it must be dehydrated and dried to achieve safe moisture, so as to prevent mildew and deterioration during storage. In view of the fact that most of the current grain drying equipment is high-temperature drying, it not only damages the quality of the grain, but also has a complicated process, high production cost and difficult operation. Therefore, it is extremely important to choose suitable storage conditions and storage equipment. At present, the storage devices developed according to actual needs are as follows: [0003] The Chinese patent (Patent No. ZL200820089519.1) provides a "new grain air dryer", which includes a hot blast stove, an air channel, a flue gas channel, a waste heat recovery channel, an induced draft fan, a flue gas discharge channel, a conveying fan, and a suction fan ,...

AI Technical Summary

Problems solved by technology

[0006] Chinese patent (patent number 201020255660.1) provides a "multi-layer air dryer", which includes a casing, a hot air box, and a conveyor belt. It is characterized in that a horizontal conveyor belt is installed in the casing, and each layer of conveyor belt is installed There is a hot air box, and there are multiple blowing outlets under the hot air box. The bottom of the casing is equipped with a hot air delivery pipe, which communicates with the hot air box. The side of the conveyor belt is equipped with a vertical hot air circulation pipe. There is a hot air circulation machine, the lower end of the hot air circulation pipe is placed at the bottom of the casing; one end of the casing is equipped with an inclined-plane conveyor belt, the top surface of the casing is left with a feeding port that matches the conveyor belt, and the other end of the casing is The lower part of the side wall has a material outlet; it solves the problems of manual feeding and material transfer in the air-drying process, which is labor-intensive and low-efficiency, and is suitable for air-drying of various small items.

[0011] To sum up, it can be seen that the current research on grain storage equipment, that is, the air dryer, has received widespread attention and has reached a certain level of research, but there are also certain problems, such as poor structural manufacturability, complex structure, and difficult to realize. Batch manufacturing; in addition, most of them use coal or electric heating, which consumes a lot of energy, and does not break away from the working principle of the dryer in essence. Therefore, combining the advantages of the above research results and abandoning its shortcomings, the present invention provides a combined air dryer
