Dewaxing Plant
What is a Dewaxing Plant?
The dewaxing process is a crucial step in the refining of vegetable oils and fats, especially those intended for use in food products where clarity and stability at lower temperatures are essential. Dewaxing removes waxes, which are natural components found in oils such as sunflower, corn, and rice bran oils. These waxes can cause cloudiness or haziness in the oil when it is cooled or stored for a longer period, affecting its appearance and stability.
De-waxing is a process that involves cooling oil to a specified temperature where wax solidifies into a slurry while the oil remains in liquid form. The bleached oil is then transferred to the Crystallizer, a specially designed vessel, where it is cooled slowly and steadily to facilitate wax crystallization for easy filtration. This is achieved by gradually lowering the temperature in stages using cold water and then chilled water. After this, some kind of oil is sent to a maturator for maturation, where the temperature is adjusted as needed to ensure proper wax crystal formation. Finally, the oil is filtered using advanced Plate & Frame Filters or Miura Super Filters.
Process of Dewaxing Plant
The dewaxing process in an oil refinery plant is essential for removing waxes from edible oils to improve their clarity and stability, especially in colder temperatures. Here's an overview of the dewaxing process designed for the oil refinery industry:
Initial Cooling:
- The oil is first cooled gradually using cold water to lower its temperature. This step is crucial to prepare the oil for further chilling and to avoid thermal shock, which can affect the quality of the oil.
Further Cooling and Crystallization:
- The oil in crystallizers where it is chilled further to a temperature of 10-15°C.
- This chilling process is managed by a chilling plant equipped with an efficient cooling system which is controlled with smart control valves and temperature sensors.
- The crystallizers are fitted with an agitation mechanism controlled by a variable drive. This allows for controlled and consistent mixing, ensuring even cooling and preventing the breaking of forming wax crystals.
Maturation:
- In some oil cases, after initial crystallization, the oil is transferred to a maturator.
- During maturation, the temperature is carefully adjusted, either increased or decreased as required, to promote the growth and stabilization of wax crystals.
- This step ensures that the wax crystals reach an optimal size for easy removal during filtration.
Filtration:
- The matured oil, now containing solidified wax crystals, is passed through advanced filtration systems such as Plate & Frame Filters or Miura Super Filters.
- These filters effectively remove the precipitated waxes from the oil, resulting in a clear and refined final product.
Quality Control and Storage:
- The filtered oil undergoes rigorous quality control tests to ensure it meets the desired specifications.
- The dewaxed oil is then stored at controlled temperatures to maintain its clarity and stability.
- Proper storage conditions ensure that the oil remains free from cloudiness even in colder temperatures.
Packaging:
- The final step involves packaging the dewaxed oil in appropriate containers for distribution.
- The packaging process is conducted in a hygienic environment to preserve the oil's quality and extend its shelf life.
The dewaxing process is critical for oils like sunflower oil (SFO),corn oil and rice bran oil (RBO), which contain significant amounts of wax. By removing these waxes, the oils maintain a sparkling appearance, even in winter temperatures, and have an extended shelf life.
