High-efficiency energy-saving grain drying machine

Abstract

The invention provides a high-efficiency energy-saving grain drying machine. The high-efficiency energy-saving grain drying machine comprises a rack, an upper layer conveying chain board, middle conveying chain boards and a lower layer conveying chain board; the top of the rack is provided with a feeding bin which corresponds to the initial end of the upper layer conveying chain board inside the rack, a discharge opening is formed in the bottom end of the rack, the discharge opening corresponds to the tail end of the lower layer conveying chain board inside the rack, hot-air inlets and wet-air outlets are formed in the side face of rack, the length of the lower layer conveying chain board is larger than that of the upper layer conveying chain board and that of each middle conveying chain board, and a moisture removing cooling fan is arranged on the upper position of the extending section of the lower layer conveying chain board. By means of the high-efficiency energy-saving grain drying machine, drying treatment on different materials can be achieved, and the material treatment amount is increased; meanwhile, thermal drying treatment is conducted firstly, and then cold-air blast drying and cooling treatment is conducted, the normal temperature state of the materials is restored on the premise that drying is guaranteed, and the requirement for high drying efficiency is met.

Description

technical field [0001] The invention relates to a material dryer, in particular to a high-efficiency and energy-saving grain dryer. Background technique [0002] As a batch and continuous drying equipment, the dryer usually uses hot air heating or electric heating for heating and drying. When the dryer is in use, the material is evenly spread on the chain plate, and the material is driven by the transmission mechanism, and the hot air passes through the material to discharge the water vapor in the material. The transmission mechanism is connected with a motor, and the purpose of controlling the drying speed can be achieved by adjusting the rotation speed of the motor and controlling the drying time. However, the existing dryers cannot meet the demand for high drying rate in industrial production. With the increase of materials, the drying rate of the dryer is severely limited. [0003] In the prior art, for example, a multi-layer chain conveyor dryer with a patent number o...

Problems solved by technology

However, there are still many defects, such as the inability to immediately provide the normal temperature materials required by the next process, or the hot air outlet and the humid air outlet are not set properly, resulting in poor drying effect, etc.
