Cooling machine remanufacturing biomass pellet plays a constraining link, as long as you need to produce large-scale biomass pellet, cooling machine is indispensable, today let us understand the working process of cooling machine

1. The SKLN series countercurrent cooler has a bulking device installed below the air lock outlet, so that the granular materials can be more evenly distributed in the middle bin. This bulking device is assembled with the upper casing

2. The hot granular materials enter the middle bin through the air lock 1 under the action of the bulking device and gradually accumulate until they reach a certain height. When the materials contact the upper feeder, the vibration motor 6 starts to work intermittently. The intermittent working time is adjustable. Under the action of the vibration motor, the rectangular frame 4 oscillates relative to the frame to discharge the materials.

3. When the discharger is feeding and the materials in the bin drop to the lower material level, the vibration motor stops working immediately and the baffle stops at a fixed position

4. If the cooler is finished working, you can manually open it and discharge the residual materials in the bin at one time.

5. If work is still needed, wait until the material layer height reaches the upper material level again, and the vibration discharge device starts to vibrate and discharge.

6. For the normal operation of the cooler, the feed amount and the discharge amount should be kept basically equal to ensure that the material has enough cooling time. During the entire working process, the cooling fan should always be turned on.

7. As the vibrating blanking device unloads the material in reciprocating motion, the material gradually and slowly descends, and the cooling air changes from cold to hot from bottom to top. In this way, during the working process, the hot material on the upper part encounters hot air, and the cold material on the lower part encounters cold air. The material is evenly and fully cooled during the downward process, becoming hard and strong, and also further reducing the moisture. The principle is shown in Figure 2.
