The flour cooler uses ambient air to cool flours after drying or cooking, making the product easier to grind. It keeps the temperature below 50°C, preventing the risk of spontaneous combustion. The equipment consists of a long drum with an agitator; a centrifugal fan draws in cooling air. The air can be ambient or sourced from other factory processes. Its simple and robust construction makes it a reliable and cost-effective solution for cooling flours.
