Meal coolers are designed to cool down the processed material known as "meal." In the rendering process, meal refers to the solid cake left after fat extraction.
After the initial processing steps, such as cooking and separation, the meal is typically hot. Cooling the meal is necessary to stabilize it, prevent spoilage, and prepare it for further processing and storage. The meal cooler helps to lower the temperature of the meal efficiently and rapidly.
The meal cooler sucks the hot air and blows the fresh air into the cooling bin. Fresh cool air circulates within the cooler, coming into direct contact with the meal, and absorbs the heat.
