Abstract

The invention discloses normal-temperature pneumatic drying equipment. Moisture and oxygen in air flow are separated by a molecular sieve dryer to increase the saturation deficiency of water in a drying medium, so that material drying under normal temperature conditions is accelerated, oxidability of the drying medium is reduced and material oxidation is inhibited; tail gas is delivered to a gas inlet to serve as inlet gas, so that the saturation deficiency of volatile components in the drying medium is reduced, volatilization of the volatile components is controlled, materials are fixed in a storage rack to be dried, shapes are not changed, normal temperature drying can be achieved, material shapes can be kept, loss of the volatile components in the materials is reduced and material oxidation is inhibited.

Description

technical field [0001] The invention relates to a normal temperature airflow drying equipment, which belongs to the technical field of circulating fluidized bed and airflow drying. Background technique [0002] Invention patent 2013107481436 discloses a rapid normal-temperature drying equipment and its normal-temperature drying method for pine pollen. The invention utilizes a fan, a circulating pipe, a material-gas separation device, and a negative-pressure circulating pipe to connect sequentially to form a circulation channel. Under the action of the fan, the material is dispersed into particles to form a fluidized state and circulates at high speed in the circulation channel. The temperature sensor installed in the positive pressure circulation pipe is used to control the temperature of the inlet air flow so that the temperature inside the machine does not exceed 50°C to achieve rapid drying at room temperature. It is suitable for drying materials that do not need to maint...
