Automatic temperature control dryer

Abstract

The invention discloses an automatic temperature control dryer. The automatic temperature control dryer comprises a heat supplying device, a drying device connected with the heat supplying device and a control device. The heat supplying device comprises a boiler, a draught fan and a heat exchanger. The heat exchanger is connected with the boiler through a high temperature liquid conveying pipe and a low temperature liquid recirculatory pipe. The heat exchanger comprises a heat radiating tube and a fan. The drying device comprises a heat exchanging chamber, a drying chamber located on the heat exchanging chamber and a conveying belt located in the drying chamber. A feeding inlet and a discharging outlet are formed in the two ends of the conveying belt respectively. A partition plate is arranged between the heat exchanging chamber and the drying chamber. A first air hole is formed in the partition plate. The drying chamber is communicated with the outside through second air holes. The heat exchanging chamber is connected with the heat exchanger. According to the automatic temperature control dryer, the partition plate is provided with the air hole, so that the upflow of hot air is not influenced and waste happening due to the fact that leaves of kudzu roots fall into the heat exchanging chamber is avoided; the second air holes are formed above the two sides of the conveying belt, so that contamination to the leaves of the kudzu roots due to the fact that sundries such as dust and tree leaves from the outside fall into the leaves of the kudzu roots directly is avoided.

Description

technical field [0001] The invention relates to a drying device, in particular to an automatic temperature-control drying machine. Background technique [0002] During the kudzu root leaf drying process, it is necessary to strictly control the temperature in the drying room. If the temperature is too high, the water in the kudzu root leaves will evaporate excessively. If the temperature is too low, it will take a long time. The control of temperature requires real-time monitoring by professional technicians, which takes a lot of manpower. In a dryer using a boiler as a heating device, the temperature in the drying room is often controlled by turning on or off the fan of the boiler. It is difficult for technicians to know when to turn on the fan or when to turn off the fan. Blow directly to the Pueraria lobata leaves, causing the Pueraria lobata leaves to be blown up and scattered. Contents of the invention [0003] The object of the present invention is to provide an aut...
