What Material Can Mesh Belt Dryer Deal With?
It's your best drying machine to deal with vegetables, chili, and it's also used to dry the food stuff like sliced dried beef, chips, carrageenan etc. Suitable for the material that has large production, large initial moisture content and the material is suitable for low-temperature drying.
Working Principle of Belt Dryer
The materials are evenly displayed on the mesh belt by the material feeder. The mesh generally uses 12-60 mesh of stainless wire net and it is drawn and moved inside the dryer by a transmitting device.
The dryer is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjusting valve. The hot air passes through the mesh belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the transmission of heat and mass. This process will bring water away from the materials.
The mesh belt moves slowly, the running speed can be adjusted according to the materials temperature. The dried materials will fall into the material collector continuously. The upper and lower circulating units can be freely equipped according to the users requirements. The unit number can be also selected according to the requirements.
Chili
It adopts special hot circulation type, the temperature is automatically controlled, the hot air is uniform, which not only saves the energy but also improves the drying efficiency. It prevents the chili from changing color during the drying process and it is easier to clean the equipment.
Dehydrated vegetables
The equipment drying area, wind pressure, blast capacity, drying temperature and mesh belt speed can be adjusted which is to adapt to the vegetable feature and the quality requirements. It is widely used to dry each kind of regional and seasonal vegetables and the fruits, such as garlic slice, pumpkin, konjak, white radish, Chinese yam and bamboo shoots, etc.
Carrageenan
The whole production line is totally enclosed type (for the materials). It is composed of swinging fabric segment, drying segment, materials discharging segment. The function of swinging fabric segment is to make the seaweed spread on the screen evenly and be sent to the drying segment at a constant speed. After the 80℃, 90℃ and 120℃ of hot air drying segments, the seaweed is discharged from the materials discharging segment.
