Desolventizer toaster

Desolventizing and drying equipment is a crucial piece of equipment used in edible oil processing, primarily in the desolventizing step of the oil refining process. This equipment effectively removes residual solvents from oils and fats, ensuring product safety and quality. Desolventizing and drying equipment typically combines high-temperature heating and vacuum technology, utilizing evaporation to separate solvents from oils and fats while preserving the oil’s nutrients. This equipment is widely used in the production of various edible oils, including soybean oil, rapeseed oil, and peanut oil. Its high efficiency and stability are crucial for improving production efficiency and ensuring food safety. In modern edible oil processing plants, desolventizing and drying equipment has become an indispensable key piece of equipment.

Working principle of desolventizing and drying equipment

Desolventizing and drying equipment separates and evaporates the solvent in the material through a combination of thermal energy and mechanical action, achieving material drying. First, the equipment provides a heat source through a heating device, heating the solvent in the material to the evaporation temperature, converting it into a gaseous state. Next, the stirring or rotating device inside the equipment ensures that the material is evenly heated while avoiding agglomeration or local overheating. The evaporated solvent gas is discharged through the exhaust system and cooled and recovered through the condenser, thereby reducing resource waste and environmental pollution. The entire process is usually carried out in a closed environment to improve efficiency and ensure operational safety. Desolventizing and drying equipment is widely used in the chemical, pharmaceutical, food and other industries. It is suitable for processing materials containing organic solvents or moisture and is characterized by high efficiency, energy saving and easy operation.

Features of the Desolventizer Toaster

• The DTDC is key for the desolventizing process in solvent extraction. It removes solvent from wet meal.
• Outstanding functionality.
• The wet meal will be directly packed after it is desolventized, toasted, dried and cooled in DTDC.
• High torque bearing capacity.
• When solvent in wet meal is removed completely, the level of urea enzyme is maintained between 0.15~0.25%.
