Square vacuum dryer

Abstract

The invention relates to a dryer and particularly relates to a square vacuum dryer comprising an inner box and a square shell, wherein the inner box is spherical. According to the square vacuum dryer, a square inner box is changed to a spherical structure to enable water drops condensed on the top of the inner box to flow towards two sides of the inner box along the radian of the top to the bottom of the inner box, so that the condensed water does not drop on materials to be dried, thereby effectively avoiding the return dropping problem of the condensed water and guaranteeing a relatively ideal drying effect.

Description

technical field [0001] The invention relates to a dryer, in particular to a square vacuum dryer. Background technique [0002] Vacuum drying is to heat and dry the material to be dried under vacuum conditions. It uses a vacuum pump to dehumidify and extract air, so that the working room is in a vacuum state, the drying rate of materials is greatly accelerated, and energy is also saved. When the material is dried in the static vacuum dryer, the material is in a static state, the shape will not be damaged, and it can be sterilized before drying. The inner box of the existing square vacuum dryer is square. When drying, the water vapor will condense into water droplets on the top of the inner box. Since the inner box is also square, the condensed water droplets will not stay along the surrounding inner walls, but will It drips back onto the material to be dried, affecting the drying effect.
