Hot Air Fruit Drying Oven Introduction
Hot air circulation drying oven is particularly designed to uniformly dry material in quantity at a temperature and has little influence on food flavor, texture and color. As the name implies, this drying oven takes advantage of circulated hot air in the oven to get materials dried, which brings high efficiency and saves the energy. Our hot air drying oven is a versatile drying equipment widely employed in food industry, pharmaceutical industry, chemical industry and other industries. We have offered drying machines with different capacities like single door hot air drying ovens, double-door hot air ovens and large scale drying ovens to meet customers' specific demands!

Hot Air Drying Oven Advantages
1. Most of the hot air is circulated in the oven, so heat efficiency is high and the energy is saved. Thermal efficiency of this drying oven can reach about 70%.
2. Adopt axial flow fan featured with low noise and high temperature resistance.
3. Equipped with adjustable air divider plate inside the oven, materials can be dried evenly.
4. Low noise, reliable and safe operation, temperature-controlled, easy installation and maintenance.
5. Drying tray is made of stainless steel, easy moving, durable and convenient to clean.
6. Heat source can be chosen from steam and electricity. Comparing these two heating ways, electricity heating way is recommended due to more convenient and secure than steam heating way.
7. Wide application: it is applicable to dry and dewater the vegetables, fruits, Chinese medicinal herb, pigment, baking finish, and other materials.

Main Parts of Hot Air Circulation Dryer Machine
1. Baking plates: 
♦Punched plate: modest permeability, suitable for particulate materials
♦ Manual multi-square plate: good permeability, suitable for bar & slice materials and loose materials
♦ Nonporous Plate: bad permeability, suitable for powder and liquid materials
2. Axial flow fan: low noise and high temperature resistance. The fan can be customized.
3. Baking vehicle: baking vehicles and its wheels are made of carbon steel or stainless steel. Their customization is also available.
4. The radiator is the auxiliary part of hot air drying oven, and the materials made are carbon steel, aluminium alloy or stainless steel. The customization of radiator is available.

Food Drying Machine Working Principle 
The food drying machine is heated by a heater through steam or electricity and a lot of hot air is circulated in the oven. The working principle of the drying machine is as follows: continuous supply of fresh air from air inlet goes into the oven and then discharge from wet exhaust outlet, which increases the heat transfer effect. Therefore the inside material moisture will gradually reduce.
