Abstract
Description
Technical Field
[0001] The utility model relates to the field of aquatic feed production, in particular to a flap type cooler. Background Art
[0002] In the early days, the feed processing market has been using drum coolers as a function of cooling pellets after pelleting. The main body of the drum cooler is a slightly inclined and rotatable cylinder. After the hot and humid expanded material comes out of the extruder, it enters the screw feeder at the front of the drum cooler from the top, and is evenly fed into the drum. A fan is installed at the outlet, and the fan exhausts air to form a cold air negative pressure flow in the drum. The material is cooled by contact with the cold air passing through the drum. During the cooling process, the material moves from the higher end to the lower end under the action of gravity with the help of the slow rotation of the drum. A forward shovel is installed on the inner wall of the drum, which continuously scoops up and sprinkles the material, increasing the cold contact area of the material to increase the cooling speed and promote the material to move forward. With the development of the market, many raw materials have changed, the requirements for larger or smaller particles, the production of submerged feed, and the introduction of large-capacity models, the drum cooler cannot solve the cooling of new materials.
