Hot Air Tray Dryer

Hot air tray dryer adopts the forced circulation of hot air inside the chamber of the oven. In the drying chamber, hot air rises above and the hot air reaches the top of the chamber. Then, hot air is circulated back to the bottom by a fan installed inside the chamber and hence the optimum amount of heat is achieved gradually inside the oven. The drying is the process that the materials heated in the trays with hot air circle, the wet moisture takes out from material will be exhausted outside at the same time.

Hot air tray dryer Description

CT-C series hot air tray dryer adopts noise elimination and thermal stable axial flow fan and automatic temperature control system. The entire circulation system is enclosed to make that the heat efficiency of the drying oven increases from 3-7% of the traditional drying oven to 35-40% of the present one. The highest heat efficiency can be up to 50%.

This tray type hot air dryer is usually used for drying herbal medicines and fruit slices. Therefore, many industries are directly named as herbal medicine drying Oven, herb slice dryers, fruit dryers, and fruit slice drying oven. The main reason is energy saving, very practical for small batches of fruit, drying of herbal medicines.

Explosion Proof Type Hot Air Oven

    If the dried material is slightly flammable and explosive, hywell machinery company can design the hot air oven as an explosion-proof type. Regarding the explosion proof hot air drying oven, it is necessary to use all the instruments and gauge related to the power supply to be explosion-proof. For example, explosion-proof temperature sensors, explosion-proof motors of fans, control cabinets are either explosion-proof control cabinets or placed in safe areas; and control cables also need to be explosion-proof. In addition to the explosion-proof use of the above instruments; the explosion proof hot air oven must have an explosion vent. When the pressure of the interior of the machine reaches a certain pressure level, the explosion vent will automatically rupture to prevent danger at the use site. Off course, the explosion-proof drying machine that need use the steam heating or hot water heating.
