Novel spiral drying machine

Abstract

The invention relates to a novel spiral drying machine, which consists of a machine frame, a feeding cabin, a drying cabin, a motor and a spiral heating tube, wherein one side of the feeding cabin is communicated with the drying cabin, the other side of the feeding cabin is provided with a feeding hopper, the back part of the drying cabin is provided with a discharging hopper, the motor is arranged under the drying cabin, a plurality of heat conducting sheets consistent with the spiral heating tube in the rotation angle are uniformly distributed and arranged on the inner wall of the spiral heating tube, and a plurality of material scraping plates transversely penetrating through the heating tube are uniformly distributed and fixedly arranged on the outer wall of the spiral heating tube. The novel spiral drying machine has the advantages that the technical problems of great occupied space and complicated regulation process of the traditional dying machine are solved, the spiral heating tube is adopted for being matched with the heat conducting sheets fixedly arranged at the inside, heat can be effectively conducted to the center of materials from the outer periphery, in addition, along with the rotation of the heating tube, the effect of turning the materials can be achieved, the heat conduction area is effectively increased, and the drying effect is improved.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, in particular to a novel spiral dryer. Background technique [0002] In food, pharmaceutical and other fields, dryers with various structures have been widely used. The dryers in the prior art generally have the structure of a horizontal production line, that is, the material is conveyed forward along the mesh belt, etc., and the hot air blown by the hot air supply device dries the material during the conveying process. For materials that are difficult to dry, in order to achieve sufficient drying effect, a longer wire body is generally required to ensure sufficient drying time, which increases the volume of the dryer and takes up a large space. On the other hand, in order to control the drying degree of materials more accurately, it is usually necessary to adjust multiple parameters such as the air volume of the hot air supply system and the running speed of the wire body. The adjustme...

Problems solved by technology

For materials that are difficult to dry, in order to achieve sufficient drying effect, a longer wire body is usually required to ensure sufficient drying time, which increases the volume of the dryer and takes up a large space

On the other hand, in order to control the drying degree of materials more accurately, it is usually necessary to adjust multiple parameters such as the air volume of the hot air supply system and the operating speed of the wire body. The adjustment process is cumbersome and the adjustment results are not satisfactory.
