Compared with the continuous type, the periodic type has great flexibility, wide adaptability, easy adjustment of temperature and moderate temperature, and can perform humidity control treatment, while the forced circulation is more uniform than the natural circulation, and the loading quantity is large, the drying time is short, and the drying efficiency is high. . Therefore, periodic circulation drying chambers are often used in production. There are many structural forms of this type of drying chamber, and their performance characteristics are not nearly the same. Periodic forced circulation drying is divided into four types according to the arrangement of fans in the drying room: indoor top fan type, indoor side fan type, indoor end fan type and jet type.

In October and November of this year, the company updated some certificates

The working capacity of the heat pump dryer is related to the environment in which it is used. After one year of continuous use, the interior of the heat pump dryer unit may become dirty and the working capacity will decrease. Therefore, special equipment inspection and equipment maintenance must be carried out. For this kind of inspection and maintenance work, it is recommended that you contact the heat pump dryer manufacturer or its maintenance department. Users should pay attention when using and maintaining this unit: all safety protection devices in the unit are set before leaving the factory, and do not adjust it by yourself. .

1. Preheating treatment: First, the control system only opens the steam injection valve, and preheats by steam injection through the evaporation water tank in the kiln. The dry bulb temperature (Td) and the wet bulb temperature (Tw) in the kiln rise synchronously. The rapid 3-hour steam injection makes the drying medium in the kiln reach Td = Tw = 9 0 ℃ or more. Then, depending on the thickness of the dry sheet, keep it for different times to preheat the sheet.

After several months of unremitting efforts, the African Cameroon company signed a cooperation agreement with our company.
