Chili Drying Machine Hot Air Circulation


1 Chilli Dryer Principle:

It uses steam or electric heater as heat resource and uses axial fan, heat exchanger to heat air in convective way. The laminar flow of hot air passes through the baking trays and will carry out heat transmission with material. Fresh air will enter into the oven from inlet to supply and then discharge from damp outlet. Fresh air is supplied, wet and hot air is discharged continuously. In this way, suitable RH in oven can be maintained. The ultimate advantage of oven is that most hot air is cycled in the oven, it increases heat transmission and saves energy source. It makes thermal efficiency of oven raise from 3-8% of traditional drying oven to about 35-50%. It uses the function of reinforced ventilation to decrease temperature difference from up to low. The oven delivered by our factory has set air distribution device. Before application, customer can adjust fan blade in order to make the temperature difference at the best state.

2 Applications

This drying oven is suitable for the material and for the product hot solidification and drying de-watering in the pharmaceutical, chemical, food, farming, side-product, aquatic product, light industry, heavy industry and so on. Such as: raw material medicine, crude drug, prepared herbal traditional Chinese medicine, plaster, powder, particle, drinking agent, pill, packing bottle, pigment, dyestuff, de-watering vegetable, dried fruit piece, sausage, plastics, resin, electric component, baking varnish etc.
