[0031] Working principle: In traditional fish meal cooling equipment, the cooling medium is usually water cooling or air cooling. Water cooling can reach a lower temperature through a water cooling unit. However, in fish meal producing areas in Africa and the Middle East, water resources are scarce and air cooling is mostly used. As customers' requirements for processing volume increase, the production capacity of many air cooling equipment cannot keep up. The processing capacity of this cooler is between 400 and 500 tons. On the basis of the original air intake, a certain air pressure is evenly input at the bottom to avoid the deposition of fish meal at the bottom of the cooler. At the same time, the stirring speed of the main shaft is accelerated to make the fish meal suspended in the cylinder as much as possible, thereby increasing the heat exchange area and cooling more evenly. The air volume and air pressure of the exhaust device and the blowing device are matched. The feed shaft has been improved in structure and is suitable for high-speed stirring and conveying; the feed shaft has an additional intermediate support under high speed conditions, the strength is improved, and the scraper is specially designed, so that it can be used for a longer time; the blowing port is set at the bottom of the cooler to achieve uniform air intake, and a dust collector can be added on the top of the shell to discharge clean gas, which is more green and environmentally friendly.
