Technical Field

The invention relates to the field of drying machinery, in particular to a high-efficiency convection drying machine.

Background technique

Generally, the drying box is formed by welding steel and thin plates. It has a reasonable structure, beautiful box shape, and is sturdy and durable. The working room can be used as a test shelf and a trolley. There is a good insulation layer between the working room and the outer shell of the box. The blower device can force the heated air in the working room to convect, thereby improving the temperature uniformity in the box. Opening the top valve can make the air in the working room fresh.
