Tunnel Dryer
A tunnel dryer is an industrial machine used to reduce moisture content from a product by drying it out. It is also known as a convection dryer because of the use of hot air to reduce the moisture content of the product. The tunnel dryer consists of a large tunnel with openings at both the ends. These openings allow for hot air to enter the tunnel and also for the product to be sent in. The tunnel can be designed in a variety of shapes and sizes depending on the size of the product that needs to be dried.
The tunnel dryer works on the principle of convection drying, which is the transfer of heat from the inside of the dryer to the surface of the product. In order to reduce the moisture content of the product, hot air is circulated inside the tunnel using fans and air is blown on the product, this causes the moisture content in the product to evaporate. Generally the speed of the fans, temperature and the amount of air are all adjustable so that the desired level of moisture content is achieved.
The tunnel dryer is used in a variety of industries to dry different types of products such as food products, wood, paper, rubber and chemicals. When dealing with food products it is important to make sure that the temperature is kept at a safe level to preserve the quality of the product. The tunnel dryer is an efficient and cost effective way to reduce moisture content from large quantities of products in a short amount of time.
The tunnel dryer is also used for other purposes such as chemical drying, which is the process of removing water from chemicals so that they can be used effectively. The tunnel dryer can also be used to shrink wrap products and to dry out textiles. The tunnel dryer is an invaluable piece of equipment that can be used in a variety of industries and can process large amounts of product and significantly reduce the moisture content.
