What is the difference between the drying method of the dehumidifying dryer and the traditional hot air blower?

However, because the physical properties of different raw materials are different, the drying temperature required is different, and a reasonable drying temperature needs to be set according to actual conditions.

The use of the dehumidifying dryer can be divided into a single machine type and a centralized type, and the single type dehumidifying dryer usually includes a dryer main machine, a drying barrel, and a suction machine. The single-machine type is suitable for a small variety of drying, which has the advantages of good drying efficiency and convenient and quick refueling.

The dehumidifying dryer includes a dryer main machine and a plurality of drying drums. Each drying drum of the dehumidifying dryer has an independent heating controller. The dehumidifying dryer can simultaneously dry several different raw materials, the dehumidifying dryer and the air volume adjusting valve. Control the amount of air in each drying drum.

The dehumidifying dryer first extracts the air in the environment to remove the moisture in the air at a low dew point, and then heats the dried air into one or more standard drying hoppers to improve drying efficiency and shorten drying time. If a conventional hot air blower is used to dry the material with moisture, it is difficult to achieve the drying effect. In addition, when the plastic is taken out from the moisture-proof sealed package and exposed to the atmosphere, it will start to absorb moisture from the atmosphere. The conventional hot air blower cannot prevent the plastic from continuously absorbing moisture, and the drying effect is poor.
