Turnkey Projects and Equipment

DTDC (Desolventizer Toaster Dryer Cooler) integrates the functions of wet meal desolventizing, drying, and cooling, having the features of simple operation and stable product quality. It is the key equipment in the desolventizing system of the cooking oil solvent extraction plant.

Since earning ASME certification in 2007, CHEMSTA has established it as a trusted global provider of high-quality ASME-standard pressure vessels. With over a decade of expertise, we have successfully delivered hundreds of ASME-compliant vessels to clients across the United States, Canada, the Philippines, and beyond, serving industries such as oil & gas, chemical processing, power generation, and pharmaceuticals.

CHEMSTA Drag Chain Extractor is solvent extraction equipment designed by our company for oil&fats and soybean protein concentrated project and is our patented product.

A screw press consists of a continuous, helical thread that revolves within a stationary, perforated cylinder. As the shaft turns, there is a reduction in volume that results in pressure in the pressing section. The extracted oil flows through the slots distributed over the barrel circumference. The foots-laden extracted oil collected in the oil pan is delivered to the crude oil cleaning section. Oil cake leaves the screw press through an adjustable conical annular cross-section and is then delivered to the further process stages.

In the preparation of oilseeds for oil extraction, the seed needs to be cleaned and then conditioned to the correct temperature and moisture. The hull is often removed from the seed to increase the protein content of the meal. Chemsta Aspirator is designed to remove loose hulls and foreign material and to heat or cool the seed.

The cooking(softening) process is vital to the pretreatment of some oilseeds. It consists of heating the seed and reducing the moisture content.
