The tunnel dryer does not have multiple heaters in the upper and lower sections of the tunnel body. A windshield is fixed on the front side of each skip to separate adjacent carts. The hot air passes vertically through the material layer and is reversed multiple times. The temperature of the hot air can be controlled in stages.
There is another type of through-flow drying equipment in which two tunnels are juxtaposed, and several drying sections are arranged along the longitudinal direction of the whole tunnel. An axial fan is installed in the upper part of each drying section of the two columns of tunnels, so that the hot air passes through the two columns in the section. At the same time, a material layer of the tunnel is input with a certain amount of outside air, and a certain amount of exhaust gas is discharged to perform partial exhaust gas recirculation.
The dehydration dryer is dedicated equipment which possesses the strong pertinence, practicability and high energy efficiency which is researched and developed based on the conveyor belt dryer. It is widely used in the dehydration and drying of various regional and seasonal vegetables and fruits. We design and manufacture the most suitable vegetable drying equipment with best quality according to the characteristics of products which need to be dried, technological requirements of customers and combining with the experience for dozens of years.
The drying area, wind pressure, blast capacity, drying temperature and running speed of mesh belt are adjustable to accord with the characteristics and quality requirements of vegetables.
