Cassava drying machine

Abstract

The invention discloses a cassava drying machine which comprises a drying box body (1) and a hot air system (2), wherein a reserved air inlet (1-6) is formed in the front side surface of the drying box body (1); a flow guider (1-5) is mounted on the reserved air inlet (1-6); a bearing hole plate (1-2) supported by a bearing frame (1-3) is arranged in the drying box body (1); a discharging hole above the bearing hole plate (1-2) is formed in a box body wall plate (1-1) of the drying box body (1); the hot air system (2) comprises a heat exchange device (2-2) and a fan (2-4); the heat exchange device (2-2) is connected with the fan (2-4) through a cold air inlet channel; and the heat exchange device (2-2) is connected with the reserved air inlet (1-6) of the drying box body (1) through a hot air outlet channel. According to the cassava drying machine, materials are dried after electric energy, vapor or the like is adopted as a heat source for heat exchange, the drying temperature and the air speed are controllable, the energy consumption is low, and the shortcoming of low material quality due to factors of incomplete water vapor discharge and the like of the sealed box body is inexistent.

Description

technical field [0001] The invention relates to a mechanical device for drying potatoes, in particular to a device for drying potatoes, especially sliced ​​or massive fresh cassava materials. Background technique [0002] At present, most of the production methods for potatoes, especially dried cassava chips at home and abroad, are the original sun-dried methods, and the disadvantage of sun-dried is that the production cycle is long, and it generally takes 5-5~ It takes 7 days to meet the moisture content requirements of the dry slices. If it is wet in rainy days, the product is prone to mold and deterioration; in addition to the long production cycle and easy exposure to rain, another disadvantage of sun exposure is that it occupies a large area, and cassava chips need to be processed separately. Layers are laid flat on the ground, requiring a large drying yard to achieve maximum output. [0003] At present, there are also methods of drying cassava at home and abroad, such...

[0002] At present, most of the production methods for potatoes, especially dried cassava chips at home and abroad, are the original sun-dried methods, and the disadvantage of sun-dried is that the production cycle is long, and it generally takes 5-5~ It takes 7 days to meet the moisture content requirements of the dry slices. If it is wet in rainy days, the product is prone to mold and deterioration; in addition to the long production cycle and easy exposure to rain, another disadvantage of sun exposure is that it occupies a large area, and cassava chips need to be processed separately. The layers are laid flat on the ground, requiring a large drying yard to achieve a large output

[0003] At present, there are also methods of drying cassava at home and abroad, such as drum dryers, mesh chain dryers, etc., but the heating of the drum dryers in the sealed drum will cause the material to zoom and cannot produce high-quality products. , while the net chain dryer not only consumes a lot of energy, but also cannot improve the output
