Drying Room | Box-Type Dryer

Drying-room

Box-type dryer, also known as a drying room or drying baker. This dryer uses pure hot air to continuously circulate through the drying chamber. In the process of heating the material, the hot air takes away the moisture generated during drying, by the way, to achieve the purpose of drying.

In the drying oven, the components such as the oven and the tray are made of stainless steel, so they are not only clean and hygienic but also durable and have a long service life. It is even equipped with an automatic control system to make it easy for you to operate.

During the drying process, the materials are placed in stationary trays, which are not prone to adhesion and can maintain the original shape and color of the materials. Based on the above characteristics, the drying room is especially suitable for drying fruits, vegetables, and Chinese medicinal materials which have high-quality requirements.

How does the drying room work?

Schematic-diagram-of-box-dryer

After laying the raw material on the Multi-layer raw material board, put it into the drying room by conveyors system or manually.

The circulating fan’s and dehumidifying fan’s running speed can be adjusted freely according to the temperature and humidity of the material.

The hot air generated by the heat source will be sent to the drying room by the circulating fan, part of the heat will be absorbed by the material and the other part forms water vapor will be discharged from the dehumidifying fan to achieve the purpose of drying.

Composition of the drying baker

This box-type dryer’s main body is a steel structure, the whole equipment is composed of the drying box, internal circulating fans, trays, electromechanical programming automatic control devices, dehumidifying fan, heat source, and so on.

The structure of the drying room
  • The drying box: The outside box is a large oven, it was made of high temperature-resistant rock wool, and the frame is supported by the 80*40 galvanized square pipe.
  • Automatic control device: The equipment adopts PLC automatic control, it can achieve temperature and humidity automatic control. The equipment will automatically stop when reaching the required temperature and humidity.
  • Circulating fan and dehumidifying fan: Both are driven by High-power fans, hot air circulation devices, and moisture discharge devices.
  • Automatic control device: The system adopts PLC fully automatic control, and the dryer equipment can realize the automatic control of temperature and humidity. The system will auto-stop when the drying temperature and humidity meet the requirements of the material.
  • Heating source: The heating way includes electric heating, oil burning, coal burning, natural gas burning, air energy heat pump, etc. (The heat source can be customized)

What are the advantages of drying oven?

  1. Drying evenly, high speed, high efficiency. The material is not easy to adhere which can  preserve the original color and taste of the material and improve the quality of products;
  2. Production environmental hygiene, equipment operation without waste gas, wastewater, or waste residue discharge;
  3. Automatic touchscreen control can accurately control the temperature and humidity of the oven;
  4. Compared with solar drying machines, the heat source of the dryer includes electricity, coal, natural gas, air heat pumps, and biomass. It can be customized  according to the user’s demands;
  5. The larger the size of the machine, the larger the output of the material, and the larger the output needs to increase the heat source;
  6. Saving the labor costs, no need to arrange full-time personnel to guard equipment.
