Drying device and a drying method

Abstract

The invention belongs to the technical field of drying treatment, and discloses a drying device and a drying method. The drying device comprises a blowing pipeline, a heater, a detecting pipeline, a humidity sensor and a controller. One end of the blowing pipeline is provided with an air inlet, and the other end of the blowing pipeline is provided with a blowing port; the heater is arranged on theblowing pipeline; one end of the detecting pipe is provided with an air return port, and the other end of the detecting pipe is provided with a sewage outlet; the humidity sensor is arranged on the detecting pipeline; the controller is connected to the heater and the humidity sensor; the controller has a manual mode and an automatic mode; in the automatic mode, when the humidity sensor detects that the humidity value of exhaust gas of an inner cavity outlet is lower than a first set value, the controller controls the drying device to stop. The drying method adopts the drying device. Accordingto the drying device and the drying method, by arranging the heater in the blowing pipeline, the drying efficiency of the drying device is effectively improved, on this basis, the humidity sensor andthe controller are arranged for cooperation, and the dryness of to-be-dried products can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of drying treatment, in particular to a drying device and a drying method. Background technique [0002] The product that has passed the water test needs to be dried before leaving the factory. When drying it through the existing operation method, the water cavity is usually blown and dried with ordinary air source. During the drying process, it is necessary to operate Personnel feel the humidity of the blown gas at the air outlet of the product to be dried to control the drying process. [0003] In the existing operation method, since the gas is not heated, the drying efficiency of the normal temperature gas is too low, the drying process takes a long time, and the drying time needs to be controlled by the operator's experience and body feeling, the degree of drying cannot be accurately controlled, and the energy consumption High or incomplete drying, easy to cause injury to the operator's body.
