Mesh belt dryer is a kind of continuous drying machine. It is widely used in food processing line. And especially it is suitable for drying fruit and vegetable chips. When you want to dry large scale food slices, this machine is the best choice for you. For this, it is helpful for you to dehydrate food effectively according to your requirements. Welcome to contact us at any time.

What are the types of belt drying machine?

There are three types of mesh belt dryer for your choice. Single stage belt dryer, multi-stage belt drying machine and multi-layer belt dryer. So you can choose them according to your needs.

This machine is suitable for drying the flake, strip and granular materials with good permeability. So you can put materials on the belt evenly through feeding port. And the speed of belt can be adjusted according to your requirements. For this, it effectively ensures the drying effect.

For multi-stage belt dryer machine, generally, there are three sets of equipment used in tandem: early drying stage, the mid-drying stage, and the final drying stage. In the early drying stage, vegetables are with high water content and bad permeability, so materials are put on the belt with a thin layer, going through a faster running belt andhigher drying temperature. After the first stage, materials are getting dried with volume shrinkage. In the mid-drying stage, you can slow the belt speed down and improve the thickness of materials. In the final stage, further, slow down the belt speed. So it is complicated to control multi-stage belt dryer machine.

This machine’s drying speed is slower and drying time is longer. So the materials are dried evenly. In addition, because of little floor area and simple structure, multi-layer belt dryer can be widely applied in drying grains. Then due to repeated loading and discharging, this dryer machine is not suitable for materials that are prone to be broken and easy to stick the belt conveyor. What’s more, after drying processing, the water content can reach 10% or less. But the quality of raw material has no damage.

What is the configuration of belt dryer?

The whole equipment consists of feeding system, hot air system, discharge system, and moisture discharge system.

  • The charging system makes the materials evenly dispersed on the screen plate and conveyed to the drying section at a uniform speed.

  • The hot air system is to provide the heat source required for drying, providing 80~120℃ hot air to the drying chamber.

  • When the conveyor belt passes through, the hot air passes through the materials on the conveyor belt from top to bottom or from bottom to top so that the materials can be dried evenly and finally discharged by the discharge system.

How does mesh belt dryer work?

The mesh belt dryer is a continuous production drying equipment. And the main heating methods are electric heating, steam heating and hot air heating. So its principle is to spread the material evenly on the mesh belt. And the belt dryer is composed of several units. Each unit circulates hot air independently. Furthermore, part of the exhaust gas is discharged by a dedicated exhaust fan.

The exhaust gas is controlled by a regulating valve. So the process of mass transfer takes away the moisture of the material. What’s more, the mesh belt is made of 12-60 steel mesh belt, which is dragged by the transmission device to move back and forth in the dryer. And this drying machine is discharged from the moisture exhaust hole to achieve the purpose of drying.

What is the application of food processing conveyor belt dryer?

How can you quickly recoup your investment after purchasing conveyor belt dryer? Of course, let the equipment play its maximum role. If the mesh belt dryer can be used for a variety of materials, its application range will be very wide and the cost will be greatly reduced. And it can also help you make profits. So what materials are suitable for belt dryer?

Sheets, strips and granular materials with good air permeability. And the temperature of the hot air is controllable from 50℃ to 160℃.

Eggplant, fruit, vegetable slices, dried fruit slices, red pepper, pepper, strawberries, walnuts, hawthorn slices, etc.

Honeysuckle, Nasturtium, Scutellaria, Salvia, Ginseng, Codonopsis, Raw Rehmannia, Rehmannia, Atractylodes, etc.

Organic pigment, compound rubber, acryl fiber, etc.

Why so many manufacturers choose FPL industrial belt dryer?

Short cycle and large output

The industrial belt dryer in the production process adopts a multi-layer structure, and the large drying area can realize mass continuous production. Furthermore, the hot air of the combustion chamber and the oven are two completely isolated parts. And all the substances formed by the combustion are discharged outdoors, which does not pollute the articles in the box and meet the export hygiene standards.

Uniform heat and mass exchange

Processed material is conveyed by a multi-layer mobile stainless steel mesh belt. Then the hot air flows through the mesh belt and the material layer above it from bottom to top. And the multi-layer circulation is turned over and dried layer by layer. For this, the heat and mass exchange is uniform and sufficient, and the production efficiency is high.

Automatic circulation of pure hot air

The heat source is a high-efficiency and energy-saving hot air stove, which is fully burned indoors. And the hot air after combustion is converted into suitable low-temperature heat through a heat exchanger. So the converted hot air is pure hot air, which is economical and environmentally friendly.

One machine with multiple uses

It adopts a lifting device with a leveler, configuring a cooling layer and a vibrating conveying device. And the discharge temperature is low, which is conducive to timely packaging. Then you do not need to adjust the thickness of the material layer. What’s more, the spreading area ranges from 50 square meters to 200 square meters. So a variety of models with different sizes can meet the needs of a variety of materials and different production scales.
