Cooler(With Pulse Dust Collector)

working principle

The fish meal comes out of the Drier at a higher temperature. After passing through the Sieve Screening and the Air-cooling Conveyor, some of the heat can be dissipated, but the temperature will still be around 50°C. Due to the violent friction and crushing effect during the crushing process, the temperature of fish meal will rise further. At the same time, because the temperature difference between fish meal and room temperature is not very big, the heat dissipation rate of fish meal will be more slow. If the fish meal is directly packaged and stacked, it is easy to generate heat phenomenon, and even spontaneous combustion will occur in serious cases, so fresh fish meal must be cooled to room temperature before storage. The role of the Cooler is to cool the fish meal at a higher temperature directly to room temperature. According to the requirements of different production lines, we are equipped with three types of coolers, which will be described below.

1.Air cooler

For larger production lines, in order to achieve better cooling effect, we usually equip with a air cooler and a water cooler. The air cooler is not very different from the cooler with air & water cooling in appearance, but the air cooler is composed of a cylindrical shell, a spindle welded with stirring wheel blades and a impulse dust collector. The fishmeal is fed from the power end, and is continuously stirred and thrown by the stirring wheel blades in the process of passing through the cooler. The heat is constantly dissipated, and the water vapor is immediately taken away by the de-dusting fan. The bag structure of the impulse dust collector can ensure that the fishmeal is not sucked into the air-suction pipeline, causing the air-suction pipeline to be blocked, thus achieving a good cooling effect.
