Tunnel dryer

Tunnel drying oven has a wide range of applications, suitable for continuous drying and curing occasions, and a wide variety of products. It is also suitable for patch red rubber curing, relay epoxy resin curing, magnetic materials and hardware, stamping parts drying after cleaning. It can be designed and manufactured according to customer requirements, and can be connected with other production lines to form a continuous drying line. Tunnel dryer is suitable for the production of hardware, electroplating, chemical industry, packaging, electronics, leather, painting, silk printing, plastic, food and other industries, replacing the traditional hot air circulating oven.

Product Description:

At present, the existing tunnel drying furnaces are generally built by hand, with air ducts in the middle and tunnels on both sides. Furnace flue gas passes through the thicker flue gas pipeline, and hot air is exchanged from the blower flue duct. The furnace body is directly connected with the earth. However, the shortcomings of this dryer are: the temperature is lost, the amount of coal burned is large, the thermal efficiency is low, the hot air exchanged turns back from the air duct to the tunnel on both sides, the hot air is not uniform in the tunnel, the drying material is not uniform, and after drying, the material must be sorted and then dried twice, the drying cost is high, the coal stove can not do anthracite treatment, resulting in environmental pollution.

Tunnel-type fruit and vegetable dryer uses a three-return smokeless hot air stove with a row of tubes. The hot air is directly blown to the material in the tunnel by a high temperature and humidity axial flow fan. The material is placed on the pallets of each layer of the truck. The material enters the tunnel from the end of the tunnel, discharges material from one side of the tunnel near the hot air stove, discharges a truck of dry material, and enters a truck of wet material at the other end to achieve intermittent drying.

Basic principles:

When the dryer is working, the materials to be dried are placed in the baking tray, the baking tray is placed on the drying car, and the drying car enters in turn from the inlet of the drying chamber. At the same time, the hot air is fed by the air supply system from the dry end of the drying chamber, and runs in reverse with the drying car, and fully contacts with the material. The drying room is automatically controlled by temperature and the moisture is automatically discharged by the exhaust fan.

Product structure:

The drying equipment adopts continuous drying operation, mainly consisting of drying chamber, drying truck, material tray, air supply system, hot stove, automatic electronic control system, etc. The drying chamber is made of metal insulation board or brick-concrete structure, and the drying plate is made of metal or other materials.
