Automatic tunnel multi-layer belt fruit and vegetable dehydrator dryer

This vegetable dryer machine is a kind of continuous production drying equipment. It is designed using high grade raw material in strict compliance with international standards. The drying system contains mainframe, heat furnace, conveyor belt, distributor, sealing device, heat preservate device, hot air input device, etc. All product contact part made of SS-304 and food grade PVC material. Owing to its quick drying process, high performance and large capacity, our machine is highly appreciated in the market. We offer this Vegetable Drying Machine in different specifications so as to meet the variegated demands of our customers.

Features of fruit and vegetable dryer:

1. Air volume, heating temperature, material retention time and feeding speed can be adjusted to achieve the best drying effect.
2. Flexible equipment configuration.Mesh belt flushing system and material cooling system can be used.
3. Most of the air is recycled with high energy efficiency.
4. Unique air distributor makes the distribution of hot air more even and ensures the consistency of product quality.
5. The heat source can be steam, heat conduction oil or gas stove.

The material is evenly spread on the mesh belt by the feeder. The mesh belt adopts 12~60 mesh stainless steel mesh, which is dragged by the transmission device to move in the dryer. The dryer is composed of several units. The circulation of hot air in each unit is independent, in which part of the exhaust gas is discharged by a special dehumidification fan, and the exhaust gas volume of each unit is controlled by a regulating valve. For dehydrated vegetables, three devices are used generally in series to form the initial drying section, the middle section and the final drying section. In the initial dry section, due to the high water content and poor air permeability of the material, the material is paved with a smaller thickness for faster running speed and higher drying temperature. The temperature of dry gas can reach above 120°C. The material residence time in the final drying section is 3~6 times that of the initial drying section, and the thickness of the paving material is 2~4 times that of the initial drying section. For the requirement that the temperature of material can not exceed 60°C, dry gas of about 80℃ can be used. Adopting multi-stage combination of drying can give full play to the performance of mesh belt dryer and the drying effect is more uniform.

The fruit and vegetable dryer is widely used in the dehydration and drying of food, aquatic products, agricultural and sideline products, dehydrated vegetables, Chinese medicinal materials, feed and chemical raw materials. The food drying equipment has compact structure, small floor space, simple operation, convenient maintenance and stable operation.
