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.

Industrial Pepper Drying Machine, Multi Layer Mesh Belt Vegetable Dehydrator Dryer Machine

The pepper dryer is a kind of continuous multi-layer mesh belt vegetable dryer. It adopts multi-layer mobile stainless steel mesh belt, and elevator device with homogenizer. The thickness of material is uniform. Due to the large drying area of food drying equipment, continuous production in large quantities can be realized. It is an ideal equipment for drying and dehydration processing of peppers, beans, Chinese prickly ash, black fungus, tremella, mushrooms and other vegetables.

The vegetable dryer is composed of the drying box, heat exchange furnace, conveyor belt, homogenization device, sealing device, heat preservation device, hot air input device, etc.

The machine has simple structure and convenient operation. The part contacting with food is made of grade stainless steel and the mesh belt adopts multi-layer mobile stainless steel mesh belt. The heat flows from bottom to top through the mesh belt and material layer. The heat transfer is uniform and full with high production efficiency. It is equipped with cooling layer and vibration feeding device that the discharge temperature is lower, which is good for packing.

Features of pepper dryer

1. Short cycle, large yield, no pollution in the drying process.
The drying oven adopts multi-layer structure, large drying area, and mass continuous production can be realized. The hot air entering the combustion chamber and oven are two parts of complete isolation. All the substances formed by combustion are discharged out of the machine and do not pollute the materials in the box, which reaches the sanitary standard for export.
2. Uniform heat exchange, sufficient, high production efficiency.
The processed materials are transmitted by multi-layer movable stainless steel mesh belt. The hot gas flows from bottom to bottom through the mesh belt and the material layer on it. Multi-layer circulation and turning, layer by layer drying. The heat exchange is even and sufficient, the production efficiency is high, and the product quality is better.
3. Energy saving, pure hot air automatic circulation.
The heat source is the energy hot air stove. The fuel is fully burned in the combustion chamber. After combustion, the hot air passes through the heat exchanger and converts the high temperature heat into the appropriate low temperature heat. The equipment makes effective use of heat energy, so that the loss of heat energy generated by combustion can be small, and the recycling of heat energy can be used scientifically to reduce the amount of coal burning.
4. Multifuntion, save money and space.

It adopts a lifting device with the homogenizer, a cooling layer and vibration feeding device with low discharge temperature, conducive to timely packaging. The thickness of the material layer is continuously adjusted. Spread area of material is from 50 square meters to 200 square meters with a variety of different sizes of models to meet the needs of a variety of materials and different production scale.

Working principle of vegetable dryer machine

After wet material is evenly fed onto the top layer of drying belt via the belt conveyor feeding system, the moving drying belt transports the wet material to the other end an drop onto the beneath layer of drying belt. The beneath drying belt then transports the wet material and moves in opposite direction until dropping onto the third layer of drying belt. At the same time, hot air is evenly blown into the dryer via the bottom air distributor. With the help of exhaust fan, the hot air penetrates the wet material on each layer of drying belt for heat transfer and take away the evaporated moisture. When wet material reaches the bottom drying belt, it is dried for discharging.

Large-scale multi-layer mesh belt pepper dryer realizes mass continuous drying operation. If the output is large, it can run continuously for a month. Under normal circumstances, the daily processing quantity of fresh goods of mesh belt pepper dryer is 2 tons to 10 tons. The pepper dryer can also be configured according to the needs of customers.
