Winterization line

A modern high-tech oil winterization line is designed to remove wax-like impurities from vegetable oil. Oil winterization production lines make it possible to obtain the best quality oil that meets all international standards.

Design and operating principle of the oil winterization line

Winterization involves slowly cooling the oil and keeping it at a low positive temperature, followed by separating the wax-containing sediment from the purified vegetable oil by filtration.

Vegetable oil winterization occurs as follows.
 

Step 1. Unfrozen (unrefined) oil enters crystallizer E2 using pump H1, into which perlite powder is supplied. In the E2 crystallizer, the oil is cooled by a refrigerant to 6°C. Afterwards, the substance is transferred in reservoir E7, from where the coolant is sent to the XM6 refrigeration machine, which reduces the temperature to the required value. The cooling process lasts at least 12 hours. During this time, while slowly stirring the oil, wax crystals form, crystallize and grow. This greatly facilitates the process of separating impurities through filtration. The filters are connected to a common system, which automates the entire process.

Step 2. From crystallizer E2, oil is pumped through pump H3 through heat exchanger T4, in which it is heated with water. The heating level is calculated very carefully to prevent melting of waxy substances and wax. Temperature is maintained using heaters and a thermostat. The location and design features of these two elements allow for the most efficient and economical use of energy resources. After this, the suspension enters a filter to separate the wax crystals from the oil.

Step 3. Oil is poured from the heat exchanger into the pressure filter F5. The oil supply level is controlled in this filter; after reaching the required amount, the filling process is completed. The crude oil is poured into reservoir E9. During the filtration process, the oil and perlite suspension is passed through a mesh partition, in which solid particles of the mixture and the filter layer remain. Thanks to this procedure, all waxy impurities, unnecessary fats and perlite are removed from the oil. After winterization, the oil enters a special container for finished products.

Step 4. After all winterization (cleaning) processes have been completed, the oil freezing line pours the purified substance into a separate container for the finished product. All cycles are checked by control systems, which significantly improves the quality of processing. The resulting product is distinguished by excellent characteristics that meet all quality standards and excellent presentation.

Upon completion of the procedure, the sediment remaining on the filter components is cleaned with dry air, which facilitates the extraction of residual oil. The air-oil flow is directed to tank L14, where the separation process takes place: air is removed and oil is drained into tank E9. The final removal of sediment from the filter is carried out using vibration ejection.
