Thermal Melt-type Winterization Filter

The external framework of the complete set of equipment is made of carbon steel. However, all the parts that come into contact with oil—such as the inlet pipe, outlet pipe, oil drainage pipe, and the filter plate frame—are constructed from sanitary-grade stainless steel, ensuring compliance with hygiene standards.

• Thermal discharging type winterization filter, the stearin discharge process does not need to dismantle the plate frame and filter cloth of filter for cleaning, but adopts hot water to circulate into the coil pipe in the plate frame, so that the crystallized wax or stearin can be discharged after heating and melting, which prevents the damage caused by dismantling and assemblying the machine for many times.
• The main structure of the equipment consists of a frame and a series of filter plates overlapped along the frame, in which the oil filter plates are arranged in a continuous manner at intervals from each other, and a filter cloth is press-fitted between the plates, which is used to separate the crystallized wax or hard stearin from the liquid oil.
• Hot water flows through the coil without contacting the oil or ester. The inlet pipe is made between plates and frames, only the filter cloth contacts the oil and stearin to retain the wax and stearin, and the liquid oil flows out from the discharge pipe.
• when the flow of the oil outlet pipe is reduced, close the valve of oil inlet pipe, and open the hot water pipe, the hot water is heated through the coil to melt the wax and stearin, naturally the wax and stearin slowly flow down from the top of the filter cloth, and flow out through the discharge pipe of ester.
• When the flow of the stearin discharge pipe decreases, close the hot water pipe, and open the blowing pipe, the residual hard stearin above the filter cloth is flushed down cleanly, and then you can open the oil inlet pipe to continue the next filtration process.

We offer a customized enclosed oil trough for the recovery of hard stearin. This design ensures that both the oil and the hard stearin do not come into contact with the air throughout the dewaxing process.

After the oil crystallizes, it flows into the winterization filtration equipment under certain temperature. Once the filter cloth is filled with hard stearin and the pressure reaches a certain level, the cleaning process can commence. Hot water can be used to melt the hard stearin, which is then expelled through the drainage pipe. Customized enclosed oil troughs and wastes troughs can be provided to enable minimum contact to air and recovery of hard stearin.

When liquid stearin in plate frame is drained completely, close the hot water valve, and lead in cooling water to maintain the required working temperature.

A precise operational procedures should be strictly adhered to.

Cleaning does not require manual intervention. When the filtering performance diminishes after a certain period of use, the entire filter cloth needs to be replaced. Simply loosen the securing bolts, remove the old cloth, and replace it with a new one.

We provide training and guidance for equipment maintenance operations.
