Provided optimum quality Winterization Dewaxing Plant is provided with a thermo-mechanical process. During this process, the solids are crystallized under various controlled temperature conditions. It ensures to provided an optimum mechanical separation. This process is exclusively applicable for oil. In the process of winterization, the oil needed for cycle of filtration is collected and goes through the steps of filling, accumulation, filtration, extrusion, drying, regeneration etc. The filtration process of this plant is totally automatic. Its process can produce wax filter cake that is very sticky.
