Coolers

A counter-flow cooler is a cooler where room temperature air is blown in the opposite direction of the flow of warm pellets; This maximises the cooling effect of the air being blown into the cooler; The amount of air being used determines the final weight and quality of the pellets being cooled; It is thus very important to control the air flow over the pellets; Too much drying during the cooling process will cause the pellets to become lighter and as a result means less money in your pocket; If the pellets are cooled too slowly, the result will be soft and cracked pellets that handle very badly; To ensure the quality of the pellets, this unit makes use of a grid to separate the fine particles from the pellets; Finer particles are collected in a bag hanging under the screen; If the cost of cooling is out of your reach, you still have to allow for cooling time in the open bags to prevent the growth of mould on the product; When warm pellets are sealed in bags, the steam will condensate on the side of the bags, causing the water to be re-absorbed and pellets crumbling in bags; If a bag is left open in the correct way, and if water content is managed properly, cooling in bags is still the way that 80 percent of the market cool their pellet production
