The dryer is a kind of widely used drying equipment, not only widely used in industry, agriculture, and also widely used in food and fruit industry. For example in the preserved fruit, candied fruit, cool fruit is also commonly used in the drying dehydration. But in the process of drying, application of special equipment in industry, agriculture, actually not too good. Here we say that a suitable preserved fruit, candied fruit, cool fruit drying equipment - tunnel dryer. The device can use tunnel car in and out of the oven, instead of relying on manual entry. This reduces the labor intensity, saving human resources, improve the quality of dry products, has simple operation, good drying quality and large output, health, etc.
Tunnel dryer equipment by the drying system, electric control system and hydraulic propulsion system. Drying system mainly consists of the dryer. (pictured above) electric control system by the electrical control box 4, operating switch 2, forward, backward, the car trip to limit switch of 12 and electromagnetic (hydraulic) valve 5. Hydraulic propulsion system by the combination of the hydraulic control valve seat 3, 6 and 7 of tubing, tank, oil cylinder 8, and push the balance beam cylinder 9, car limit lever to 10, adjustable propulsion and the car stop to 11. 1 is the universal wheel car hydraulic propulsion skip.
Tunnel car working principle is: will charging car hydraulic into the dryer door (wind blowing end) advancing the drying tunnel, and through the door switch, push the car into baking tao when the small car full of baked road (after 20 ~ 40 cars), hydraulic propulsion self-return stop; When skip car, car ingredients, can be launched at the other end of the drying tunnel or pull to hydraulic hydraulic propulsion in into the door. Without personnel enter the drying tunnel. Under the condition of automatic hydraulic cart in and out of the device can be cycle shunting and feeding, material, and health, safety, convenient operation, energy saving.
The working principle of the tunnel dryer:
Tunnel dryer adopts double drying tunnel structure, each path is an independent unit of work, sustained in a unit of work fore and aft to connect with each other, was escorting Structure, hot air circulation drying medium, constitute a complete working system. Electric hydraulic control and promote the car is the main equipment. Skip from outlet around 7 push dryer tunnel. By baking channel 8 pushed forward the hydraulic oil cylinder. Hydraulic propulsion skip moving direction and the direction of tunnel hot air flow, in contrast, when the dry product was gradually after drying, skip are photographs from around the end door.
Hydraulic automatic working order of in and out of the cart: artificial before entering car - cylinder push - cylinder limit in place - cylinder back - after the oil cylinder limits in place to stop; Artificial after bake, fill the car into the car - cylinder push - full car limit in place - cylinder back - after the oil cylinder limit stops in place. Oil pump unloading oil cylinder will not work.
