Description

Drying Equipment {DRYING MACHINE}

The present invention relates to a drying apparatus, and more particularly, to a drying apparatus in which a smooth agitation and transfer of a dry matter is made in a drying chamber, and thermal efficiency is excellent and safety is improved.

Drying equipment is a device that removes water or solvents contained in the dry items by directly or indirectly heating the dry items by using hot air, superheated steam, electricity and electromagnetic waves. The dry items that can be dried in the drying device are agricultural and marine products. , Processed foods, wetted minerals, industrial final products, food waste, powdered or sludge, etc., and various other dry matters.

The drying method of the drying apparatus is classified into direct heating type and indirect heating type. The indirect heating type is composed of a drying chamber in which a dry matter resides and a heating medium circulation chamber in which a heat medium circulates. It is a drying method which does not contact, and direct heating type is a drying method in which the heating medium and the dry matter such as heated air and superheated steam are in direct contact with each other to evaporate moisture.

Conventional drying apparatuses include a variety of apparatuses including screw dryers, thin film dryers, fluidized bed dryers, rotary dryers, and multi-stage multilayer dryers. Among them, in the rotary dryer in which a cylindrical drum is installed laterally to rotate the drum itself and the heating medium and the dry matter are directly contacted or indirectly contacted and dried in the drum, the drum corresponds to a drying chamber that has a large weight and accommodates the dry matter. Since it rotates itself, the capacity of a drive part is large, power is excessively consumed, and stirring of a to-be-dried thing is not smooth. In addition, the solids adhered to the inner surface of the drum may cause the adhered dry material to be over-dried, and the over-dried dry matter may be easily dusted and mixed with the drying hot air. Due to the solid matter adhered to the thermal conductivity, the thermal conductivity decreases. In particular, the installation of a drum with a relatively small diameter and a long length in the transverse direction is difficult to take a lot of site.

In addition, among conventional drying apparatuses, dryers equipped with a raker for agitating and conveying a dry matter inside the drying chamber and allowing the dry matter to be in direct or indirect contact with the heat medium are compared to a rotary dryer which rotates by installing the drying chamber itself in a lateral direction. Therefore, the driving part is small, the power demand is small, and the site is small, so the land is suitable for the reality of Korea, and the agitation is made by the small weight of the raker, so the power demand is low.

It is advantageous. However, in the conventional multi-stage drying apparatus, the raker used for stirring and conveying the dry items is focused on the transport of the dry matter and the scraping of the bottom surface, so the drying efficiency (the amount of evaporated water per unit calories) is low and the drying time is long. It takes

In addition, there is a risk of dust explosion at high temperatures if the organic dry matter is overdried and dusted. However, the conventional drying apparatus may be attached to the dry matter on the ceiling surface or the bottom surface, and the attached dry matter lowers the thermal conductivity and is excessively dried and dusted, so there is a management difficulty in cleaning the interior periodically.
