The D.T.D.C system is called Desolventizing Toasting Drying and Cooling system. It is one part of cooking oil solvent extraction plant, and there are other three parts: solvent extractor, miscella oil evaporation system and solvent condensing and recycling system. As its name means, the main function of D.T.D.C system is to remove the solvent in wet meal through toasting, drying and cooling process, and then get high-quality meal, which can be as animal feed.

The working principle of D.T.D.C system:

Wet meal is sent into desolventizer-toaster by sealed auger, and firstly drops on the heating plate of the first pre-desolventizing layer, then the meal is heated by indirect steam to remove part solvent. With the turning of the paddles, material drops to the next pre-desolventizing layer, then to another. And after three levels, material drops to the main desolventizing layer. There are some direct steam nozzles on the chassis of the layer which can spray direct steam with the pressure of 0.05~0.1MPa, thus the solvent in wet meal can be removed completely.After desolventizing, the water content in meal is high, so drying meal with hot air is necessary.

The advantages of D.T.D.C system:

1. Reasonable steam spraying can keep the temperature of vapour phase low at the export of the D.T. And energy consumption also can be reduced greatly.

2. In airtight condition, desolventizing solvent meal effectively and adopting reasonable way to spray direct steam evenly. Compared with traditional desolventizing equipment, this machine can make the residual solvent in meal reach to minimum.

3. In each part of the D.T.D.C system, material particles have the same residence time, so products have high stability and quality.

4. The vapour phase temperature of D.T.D.C system can be achieved by automatically adjusting the amount of direct steam.

This is the brief introduction of D.T.D.C system in cooking oil solvent extraction plant. Henan Doing Mechanical Equipment can provide complete plant design based on customer's production requirement. If you want to build up a more than 30tpd cooking oil processing plant, you can consider using cooking oil solvent extraction plant, because it will produce more oil than pressing plant.
