Dingsheng Machine Explores the Degumming Process in Palm Oil Refining: Efficiency and Innovation
Date:Dec 18th, 2024
Palm oil, derived from the fruit pulp and kernel of the oil palm tree, stands as one of the "Big Three" vegetable oils alongside soybean and rapeseed oils. Its widespread production, consumption, and trade make it a cornerstone of the global edible oil market. Predominantly cultivated in Southeast Asia and Africa, palm oil production is led by Indonesia, Malaysia, and Nigeria, collectively accounting for 88% of global output. With an annual consumption of approximately 6 million tons, China has emerged as the world's largest palm oil importer, holding a 20% market share.
Palm oil undergoes refining and fractionation to produce products of varying melting points, widely utilized in the culinary, food processing, and oleochemical industries. The refining process is essential for removing impurities and meeting the standards for edible oil. The stages include: crude palm oil filtration, degumming, deacidification, bleaching, and deodorization.
The Critical Role of Degumming in Palm Oil Refining
Degumming is a pivotal first step in refining crude palm oil, aimed at removing phospholipids and other gummy substances. The primary goal of degumming is to extract two types of phospholipids present in crude palm oil:
Hydratable Phospholipids: Removed via water degumming.
Non-Hydratable Phospholipids: Removed using phosphoric acid degumming.
Process Overview
Preparation and Heating: Crude palm oil is stored in a buffer tank before passing through a heat exchanger to reach the required temperature.
Phosphoric Acid Addition: A calculated amount of phosphoric acid, stored in a dedicated tank, is mixed with the oil. The quantity depends on the gum concentration and the type of crude oil.
Mixing and Reaction: The oil, acid, and heated water are combined in a degumming tank, where gums and oil begin to separate.
Separation: The liquid is sent to a separator, where colloidal particles and gum impurities are extracted into a waste stream.
Drying: The degummed oil enters a vacuum dryer to remove moisture, achieving the required concentration for refined oil.
Advantages of the Degumming Process
Efficient Phospholipid Removal:
Degumming ensures the effective removal of both hydratable and non-hydratable phospholipids, preparing the oil for subsequent refining stages.
Improved Oil Quality:
By removing impurities early in the refining process, degumming enhances the final product's stability, clarity, and shelf life.
Environmental Sustainability:
Modern degumming processes minimize waste and reduce the environmental impact by ensuring efficient resource utilization.
Cost-Effectiveness:
Efficient separation of impurities reduces the workload in later refining steps, saving time and operational costs.
