Product Details

The palm fruit digester is used to mash and heat sterilized palm fruit before the pressing stage. Proper digestion is essential for maximizing oil extraction efficiency — it breaks down the fruit tissue and releases the oil from the cell walls.

Key Features:

Vertical or horizontal design to suit different plant layouts
Steam heating jacket maintains optimal digesting temperature (90-100°C)
Robust stirring arms ensure thorough mashing and even heating
Continuous operation with automatic feeding and discharging
Made of food-grade stainless steel for hygiene and durability

Working Principle:

After threshing, the palm fruit falls into the digester, where rotating stirrer arms mash the fruit into a homogenous pulp. Simultaneously, steam is injected through the jacket to heat the pulp to 90-100°C, which reduces oil viscosity and improves pressability. The digested mash is then fed directly into the screw press for oil extraction.
