Cold Stability Solutions
De-Waxing / Winterization
For refining products to be bottled as edible oils, winterization is required to achieve the necessary cold stability. Winterization prevents crystallization & clouding of the waxes contained in the oil at ambient temperature.
Winterization Process
For refining products to be bottled as edible oils (e.g. sunflower seed oil or corn oil) winterization is required to achieve the necessary cold stability.
Winterization prevents crystallization & clouding of the waxes contained in the oil at ambient temperature.
In the winterization process the oil is cooled by heat exchange with cold water to a temperature between approx. 5 & 10 degree C. Crystals causing oil clouding are formed during a mature period of up to 24 hours & are subsequently separated.
Crystal Separation
This is implemented by continuously adding filtering aids & filtration via horizontal filters.
The process achieves clear, cold-stable oil suitable for bottling and long-term storage.
