Dewaxing

Objective: Our dewaxing process is specifically designed for the removal of glycerides and waxes from sunflower and rice bran oils. We prioritize achieving optimal crystal growth and filtration efficiency through controlled cooling and precise temperature management.

Key Process Details:

1. Cooling and Crystal Growth:
   • The dewaxing process begins by cooling the oil to the required temperature.
   • Proper retention time is allowed for wax crystals to grow within the oil.
   • The cooling is facilitated with a plant that includes a crystallizer with maximum oil-to-heat exchanger area, allowing efficient cooling with water.
   • The plant is designed to provide adequate cooling and maximum maturation time to ensure the formation of bold crystals and excellent filtration.
2. Controlled Temperature Reduction:
   • Bleached oil is pumped from the storage tank and fed into the crystallizer.
   • The cooling process is gradual and slow, ensuring a continuous decrease in temperature at an optimum rate to prevent thermal shock to the oil.
   • This controlled cooling process promotes the formation of larger crystals within the oil.
3. Maturation and Filtration:
   • After reaching the required minimum temperature, the oil is given the optimum residence and holding time for the maturation of the winterized crystals.
   • The temperature is maintained at an optimal level to ensure efficient filtration.
   • The oil is gravity-fed to Plate and Frame Filters, providing the best capacity and quality.
   • After oil filtration, the filters are cleaned with air to minimize oil residue in the wax.
