As the name suggests the Refining operation is carried out in Batches.
The steps involved are -
1. Degumming and Neutralization: In Batch Plant degumming and neutralizing is carried out simultaneously in a vessel called Neutraliser. The crude oil is made to react with weak solution of phosphoric acid for separation of gums and is further treated with caustic soda. Caustic soda reacts with free fatty acids forming soap. The soap is removed by decantisation after removal of the soap oil is given a wash with hot water, oil and water is separated by decantisation. More details are available on request.
2. Bleaching: Bleaching is second step in refining after degumming & neutralising. The oil is bleached with the help of bleaching agent. Normally bleaching earth and / or activated carbon. The bleaching agent absorbs the colouring matter from the oil. The oil is filtered through filter press wherein bleaching agent and oil are separated out. The resultant oil is bleached oil and very much light in colour then the neutralised oil. More details are available on request.
3. Deodorisation: The oil after bleaching is practically pure, but contains minute quantities of original odoriferous matter. Also the chemicals used during neutralisation and bleaching impart their odours to the Oil. It is essential to remove the odour prior to the marketing of the oil. The deodorization process is steam distillation process carried out in a vessel called Deodoriser. The oil is heated to a high temperature under high vaccum and open steam is injected. The odiferous matter is distilled off. The oil is passed and cleared through filter to get sparkling oil. More details are available on request.
Quality Control & Process Efficiency:
The process offered by TROIKA is such that the final quality of refined oil is automatically attained with minimum human effort. Lowest refining losses, consumption of utilities such as steam, power and water, lowest consumption of chemicals such as caustic soda, bleaching agents and degumming agents and minimum operating personnel are salient features of TROIKArefining plants.
TROIKA the technocrats to vegetable oil industry since 1971 have supplied equipment at more than 260 installation spread over Twenty Five countries. Whether for oil milling plants, Solvent Extraction plants or Refining plants or Hydrogenation plants you can always count on TROIKA.
