Automatic Drying Hot Air Force Circulation Infrared Furnace

Introduction

The tunnel dryer does not have multiple heaters in the upper and lower sections of the tunnel body. A windshield is fixed on the front side of each skip to separate adjacent carts. The hot air passes vertically through the material layer and is reversed multiple times. The temperature of the hot air can be controlled in stages.

There is another type of through-flow drying equipment in which two tunnels are juxtaposed, and several drying sections are arranged along the longitudinal direction of the whole tunnel. An axial fan is installed in the upper part of each drying section of the two columns of tunnels, so that the hot air passes through the two columns in the section. At the same time, a material layer of the tunnel is input with a certain amount of outside air, and a certain amount of exhaust gas is discharged to perform partial exhaust gas recirculation.

Features:

It is mainly used for the drying of agricultural and sideline products such as fruits and vegetables, Chinese herbal medicines, pet foods, etc. Due to the use of hot air convection heating, there is absolutely no pollution to the products, which is in full compliance with food hygiene standards. Hot air is recyclable and thermal efficiency is significantly improved. The baking tray can be made of plastic mesh plate or stainless steel mesh plate, and can also be flexible and convenient by using wooden strips, wire mesh, bamboo nets and sieves.
