Gums Drying / Lecithin Production

During the degumming stage of edible oil refining, gums are separated from crude oil. These gums contain phospholipids, oil, and moisture. Instead of treating them as waste, they can be processed into high-value lecithin through a controlled drying and finishing process.

Wet gums obtained from the degumming process are first conditioned, heated, and subsequently processed through a series of scraped surface heat exchangers and evaporators, where moisture is progressively removed to achieve very low residual levels i.e. < 0.5%. The drying is carried out in multiple stages under controlled vacuum conditions to ensure efficient moisture reduction. The final product is light in colour, enhancing its commercial value.

Key Features

Production of edible/ pharma grade/ Export quality lecithin

Specially designed scrapped surface heat exchanger for efficient heat transfer

Hermetically sealed system prevents gum oxidation.

Highly robust and maintenance free

Use of low-pressure steam for no scorching of gums to retain the original colour

Powder Lecithin: Dried gums are processed further for Lecithin powder manufacturing where the lipid portion is extracted with the solvent acetone and further dried with spray drying technique to get quality product. Soy Lecithin in all forms is a very good emulsifier and is typically used in confectionaries, bakery products and pharmaceutical industries.
