Desolventizer DTDC

Desolventizer DTDC Functions and Applications

The DTDC (Desolventizer Toaster Dryer Cooler) is a key piece of equipment in oil extraction  plants for desolventizing wet meal and inactivating antinutritional factors in meal. It integrates desolventization, drying, and cooling functions into one unit, offering simple operation and stable product quality. It is primarily used for desolventizing, toasting, drying, and cooling wet meal exiting the solvent extraction unit.

Desolventizer DTDC Working Principle

• Pre-desolventization Layer: Indirect steam heating raises the temperature of the wet meal, evaporating part of the solvent.

• Steam Desolventization Layer: Direct steam is used to heat the wet meal, accelerating solvent evaporation, while stirring and negative pressure enhance the desolventization process.

• Drying Layer: Hot air is used to further dry the wet meal, reducing moisture content.

• Cooling Layer: The dried meal is cooled to near ambient temperature, facilitating storage and transportation.

Desolventizer DTDC Technical Features

• Unique Perforated Plate Design: Ensures uniform penetration of the mixed gas through the material layer, preventing wet cake from falling through the steam holes, thereby saving direct steam consumption.

• Automatically Controlled Discharge Valve: Maintains a constant material level in the desolventization layer and ensures sufficient desolventization time.

• Automatic Material Gate System: Features a fully rolling bearing design for flexible operation, extended service life, and effective prevention of solvent leakage.

• Wet Collector: Utilizes misting nozzles to capture fine meal particles from the exhaust mixed gas.

• Off-Center Bent Stirring Blade: Ensures thorough material agitation.

Desolventizer DTDC Advantages

• Inactivation of anti-nutritional factors: Effectively destroys anti-nutritional components such as urease and trypsin in meal, enhancing its nutritional value.

• Control of protein denaturation: Effectively improves the NSI index of meal.

• Adjustment of meal color, aroma, taste, and particle size.

• Reduce residual solvent and regulate moisture content: Ensure the lowest solvent consumption during production and safe use of meal.

Desolventizer DTDC Overall Features

The DTDC steam stripping machine is the optimal equipment for solvent removal from wet meal in oil extraction plants, efficiently completing the processes of solvent removal, roasting, drying, and cooling of wet meal. Its unique design and advanced technical features enable it to excel in reducing solvent consumption, improving meal quality, and achieving energy conservation and reduced consumption.
