Description

A constant temperature blast dryer

technical field

The utility model relates to drying equipment, in particular to a constant temperature blast dryer.

Background technique

The blast dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, and is used to dry objects. The dryer evaporates the moisture in the material by heating to obtain a solid material with a specified moisture content. In the process of plastic modification and injection molding of plastic parts, the plastic powder raw material absorbs water. If the plastic product is directly heated, it will cause the material in the plastic product to decompose, resulting in poor performance and appearance. Therefore, these moisture-absorbing raw materials need to be dried before processing before further processing. At present, the dryer is mainly used to dry the pellets or powder. The dryer is composed of a material box and a heating device connected by pipelines. The heat is brought into the material box by blower blowing. The bottom of the material box is in the middle, and the air outlet is on the top of the material box. In the actual work of such a dryer, part of the heat is lost before it is brought into the material box by the blast. The uneven temperature distribution in each part of the material box leads to a decrease in the performance of the raw materials after processing, and leads to appearance defects in the finished product, which seriously affects the quality of the plastic product
