Problems solved by technology

[0003] In such a decompression drying device for powder and granular materials, in order to uniformly heat the heat conduction fins, it is necessary to use a heater with large power consumption. In addition, in order to uniformly heat the powder and granular materials stored in the hopper For heating, it is necessary to arrange heat transfer fins densely, so there is a problem that the cost of the device becomes high
In addition, there is a problem that cleaning performance is deteriorated due to densely arranged heat conduction fins

Abstract

Disclosed is a depressurization type drying device (1) for powder and granular material comprising a hopper (20) for storing powder and granular material, and a depressurization means (3) for depressurizing the inside of the hopper, wherein the device is provided with hopper outer periphery heat retaining units (40, 26) arranged on the outer periphery of the hopper, a heated gas supply unit (4) for supplying heated gas to the hopper, and a control unit (80) for controlling the heated gas supply unit to supply gas which has been heated to a preset temperature.

Description

technical field [0001] The present invention relates to a decompression drying device for powdery or granular materials, comprising a hopper for storing powdery or granular materials and a decompression mechanism for decompressing the inside of the hopper. Background technique [0002] As a conventional decompression drying device for powdery or granular materials, the following method has been adopted: in the state where the hopper for storing powdery or granular materials is sealed, the inside of the hopper is depressurized by a decompression mechanism, and by densely arranged The heat conduction fins on the inner peripheral wall of the hopper heat the powdery or granular material stored in the hopper (see, for example, Patent Document 1 and Patent Document 2 below). [0003] In such a decompression drying device for powder and granular materials, in order to uniformly heat the heat conduction fins, it is necessary to use a heater with large power consumption. In addition,...
