Movable portable three-temperature-zone drying machine

Abstract

The invention discloses a movable portable three-temperature-zone drying machine . The movable portable three-temperature-zone drying machine comprises a box piece machine body, an upper feeding hopper, a hot air fan, a fixed frame piece, an inner flow dividing temperature control assembly and layered drying assemblies, wherein the upper feeding hopper is vertically fixed to the upper part of the box piece machine body in a penetrating mode, the fixed frame piece is transversely installed on one side of the box piece machine body through a locking screw piece; a hot air fan is installed on the fixed frame piece, and the hot-air fan heats and dehumidifies external airflow to form dry heat flow; a main drainage pipe is fixed to the box piece machine body in a penetrating mode, and one end of the main drainage pipe communicates with the hot air fan and discharges the dry heat flow into the box piece machine body; the multiple layered drying assemblies are arranged in the box piece machine body, the inner flow dividing temperature control assembly is further arranged in the box piece machine body, the inner flow dividing temperature control assembly disperses and conveys and guides the dry heat flow introduced into the main drainage pipe into the layered drying assemblies, and driving guide wheels are further symmetrically arranged at the four corners of the lower end face of the box piece machine body.

Description

technical field [0001] The invention relates to the technical field of crop drying equipment, in particular to a mobile and portable three-temperature zone dryer. Background technique [0002] China is an important grain country in the world. In the main grain producing areas, due to the large output, the purchased grain has a large moisture content, which exceeds the standard moisture content for storage. If the temperature and humidity in the environment of the grain meet the conditions for microbial growth and reproduction, a large number If the grain purchase period catches up with cloudy and rainy days, the chance of mildew will be greater; in addition, even if the grain with the standard moisture content is safe when it is put into storage, there will still be a phenomenon of natural moisture return. It also needs to be dried regularly to ensure that the grain does not go moldy; the hot air heating efficiency of the dryer in the prior art is low, the equipment cannot b...

Problems solved by technology

[0002] China is an important grain country in the world. In the main grain producing areas, due to the large output, the purchased grain has a large moisture content, which exceeds the standard moisture content for storage. If the temperature and humidity in the environment of the grain meet the conditions for microbial growth and reproduction, a large number If the grain purchase period catches up with cloudy and rainy days, the chance of mildew will be greater; in addition, even if the grain with the standard moisture content is safe when it is put into storage, there will still be a phenomenon of natural moisture return. It also needs to be dried regularly to ensure that the grain does not go moldy; the hot air heating efficiency of the dryer in the prior art is low, the equipment cannot be moved, and it is inconvenient to use; The moisture content of the drying material of the chain plate gradually decreases, and it is easy to become scorched due to over-drying; and in the large-scale drying work, some crops that sink to the bottom cannot be completely heated and dried; therefore, it is necessary to propose a Mobile and portable three-temperature zone dryer to solve the above problems
