Product Working Principle

One. Features of the Belt-Type Continuous Drying Machine

1. The belt-type continuous dryer uses hot oil, steam, or hot air and flue gas as heat sources. It dries the material by controlling the parameters of the drying medium and utilizing the heat transfer of the gas medium through convection.

2. This machine is a continuous dryer. Wet material enters from the inlet end, gets dried during operation, and is discharged from the outlet end as dry material.

3. This unit is a forced circulation dryer, with the fan located at the top of the dryer. It is divided into positive and negative pressure zones according to the air flow direction.

4. Airflow Method: 1) Airflow that horizontally passes through the dried material is called horizontal airflow; 2) Airflow that passes through the dried material is called crossflow airflow.

2. Working Principle of the Belt-Type Continuous Drying Machine

1. Wet materials are conveyed into the feeding hopper of the mesh belt dryer by a belt conveyor. The mesh belt is driven by a speed-regulatable transmission mechanism, continuously advancing over the materials. After the material reaches the required dryness by adjusting the running time, it is discharged at the outlet.

2. The drying medium inside the machine is heated by a heater (heat source: hot oil, steam) or hot air (flue gas) and then horizontally or crossflows through the material, causing the moisture in the material to vaporize and evaporate, thereby achieving drying.

The working principle is briefly described as follows: After the fan starts, it first blows the dry medium towards the heater or hot air tube. After heat exchange, the temperature of the dry medium increases, and the heated medium is blown towards the material to raise its temperature, causing the moisture on the material surface to vaporize and evaporate. The steam is carried away by the medium and discharged at the exhaust port. The remaining medium is then吸入 by the fan for recirculation, and this cycle repeats, resulting in the drying of the material.

Product Performance Features

The BYD Multi-layer Dewatering Vegetable Belt Dryer dries materials by gravity, achieving even flipping of the material as it gradually falls from the upper conveyor belt to the lower one. Hot air fully contacts the material for drying, evaporating moisture to enhance the drying quality and ensure uniformity. The feed and discharge ends are at both ends of the equipment. Feeding is automated using a material feeding machine and is controlled by variable frequency, which can adjust according to the properties of various materials. The discharge end features automatic discharge for easy operation. This equipment has low production costs and high profit for businesses. It is an ideal advanced drying processing equipment for the dehydration of vegetables, herbal medicine slices, and fruit industry.

Product Application Range

Ideal for a variety of vegetables such as bok choy, cabbage, carrots, cucumbers, pumpkins, cassava chips, green beans, scallions, traditional Chinese medicine slices, yams, goji berries, ginger slices, scallions, bamboo shoots, taro seeds, and more, including root, stem, and leaf vegetables, fruit items, betel nuts, jujubes, grapes, goji berries, apple slices, kiwi slices, and other materials. This dehydration drying equipment for various vegetables, herbs, and apple products is highly automated and suitable for materials that cannot withstand high temperatures. The series features fast drying speed, high evaporation intensity, and high product quality.
