Dingsheng Machine Showcases Upgraded DTDC for Better Wet Meal Processing Performance
Date:Dec 8th, 2025
Dingsheng Machine is excited to introduce its upgraded DTDC (Desolventizer Toaster Dryer Cooler), a cutting-edge piece of equipment designed to streamline the solvent extraction process in edible oil production. This high-performance unit combines desolventizing, drying, and cooling in one integrated system, offering enhanced efficiency and product quality for large-scale oil processing operations.
Optimized for Solvent Extraction and Meal Quality
The DTDC system plays a crucial role in wet meal processing within solvent extraction plants. By efficiently removing solvents from the wet meal, the upgraded DTDC ensures optimal meal flavor, enhances protein quality, and improves the overall nutritional value of the meal, all while reducing urease activity to ≤0.3mg N/g/min at 30°C.
This innovative system is engineered to handle processing capacities ranging from 100 to 6000 tons per day, making it suitable for a wide range of industrial-scale operations. It is particularly effective in improving meal flavor, making it more suitable for use in animal feed and other applications where high-quality meal is required.
Key Features of the Upgraded DTDC
1. Efficient Solvent Removal: The DTDC system is designed to efficiently remove solvents from wet meal, ensuring high-quality meal production with minimal residual solvent.
2. Improved Protein Quality: By reducing urease activity to ≤0.3mg N/g/min at 30°C, the system helps preserve protein quality, making the meal more nutritious.
3. Energy-Efficient Operation: The integrated system reduces energy consumption by optimizing desolventization, drying, and cooling processes in one unit.
4. Temperature Control: The meal is cooled to 5-10°C above ambient temperature, ensuring the product remains stable and retains its nutritional value.
Processing Stages in the DTDC System
1. Pre-Desolventizing: The first stage involves 4-layer indirect steam heating, which begins the solvent removal process in a controlled environment.
2. Desolventizing: Direct steam treatment is used to remove solvents from the meal, ensuring that all residual solvent is effectively eliminated.
3. Drying: The hot air system effectively dries the meal, making it ready for cooling and further processing.
4. Cooling: After drying, the meal is cooled using a temperature-controlled system that maintains the quality and consistency of the final product.
All sections of the DTDC feature agitators and level controls, ensuring even distribution of heat and efficient processing at all stages.
Benefits of the Upgraded DTDC
Stable Operation: The integration of desolventizing, drying, and cooling in a single unit ensures consistent performance and product quality.
Energy Efficiency: Optimized for energy savings, the DTDC reduces overall energy consumption during meal processing.
Enhanced Meal Quality: The reduction in urease activity ensures that the meal maintains its nutritional integrity, making it ideal for animal feed and other uses.
Improved Flavor: The DTDC not only enhances the protein quality but also improves the flavor of the meal, making it more desirable for various applications.
Applications of the DTDC
The DTDC is ideal for large-scale solvent extraction plants involved in the processing of vegetable oils, particularly for extracting oils from soybeans, canola, sunflower, and other oilseeds. The high-quality meal produced by the DTDC is used extensively in animal feed, health supplements, and other industrial applications.
Conclusion: A Key Upgrade for Oil Extraction Plants
With its superior efficiency, energy savings, and ability to produce high-quality meal, Dingsheng’s upgraded DTDC system is a game-changer for solvent extraction plants. By integrating desolventizing, drying, and cooling processes into one unit, this equipment maximizes both operational efficiency and product quality.
