Desolventizer Toaster is the best equipment for desolventizing the extracted wet meal to realize its desolvation and drying. It can be used to cool the extracted meal with the temperature of 5-10 ℃ higher than ambient temperature for direct packaging and storage. Four layers of indirect steam are used for heating in pre-desolvation. The evaporation layer uses direct steam and the dry layer uses hot-air. Each material layer is provided with a stirring and material level control device to achieve fully pre-desolvation, evaporation and drying effect and reduce the solvent residues effectively. The urease activity of the meal would be reduced to 0.3 mg nitrogen /g/min at around 30℃ on the condition of maintaining the activity of protein at the most extent.
 
The advantages of Desolventizer toaster:
1.To inactivate and destroy the anti nutrients like urease and trypsin in the meal to improve its utilization value;
2.To control the degree of protein denaturation and effectively improve the NSI index of meal;
3.To improve the color and flavor of the meal;
4.To reduce the residual solvent in the meal and regulate the moisture of the meal, so as to ensure the lowest solvent consumption and the safe use of the meal
 
Characteristics of Desolventizer-toaster:
1.Desolventizer-toaster is the main equipment of desolventizing system of leaching plant, capable of removing the solvent in the wet meal.
2.Desolventizer-toaster has perfect functions. Pre-desolvation, evaporation, drying and cooling of wet meal can be achieved. The wet meal after desolventizingy can be packaged directly;
3.With large transmission torque and load weight;
4.After complete desolventizing of the wet meal, urease activity would be remained at 0.15~0.25, which improves the quality of oil and meal.
