The Dryer-Cooler (DC), when used with the Desolventizer-Toaster (DT), will dry and cool almost any solvent-extracted, vegetable-oil-bearing meal. The drying and cooling is accomplished by injecting heated air in the drying section and using ambient-temperature air to cool the meal in the cooling section. The evenly distributed flow of hot air and cool air in a true counter-current system is highly efficient and reduces energy costs while producing a meal with the desired characteristics for sale and storage.
The DC unit works equally well combined with a DT or used as a separate unit, depending upon customer preference.
The DC used in a specialty application is a direct contact dryer that uses the heat and water in the product to dry and simultaneously cool the product with minimal air.
