Crystallization Tank

Palm oil fractionation is the core process that separates palm oil into high-value palm olein and palm stearin by leveraging the melting point difference between the oil’s solid and liquid fractions. The crystallization tank is the essential, specialized equipment in this entire process.

What is a Crystallization Tank?

The crystallization tank is a closed container with stirring and cooling devices. It separates high-melting-point stearin from low-melting-point olein in palm oil through controlled cooling and crystallization, to produce palm oil fractions with customized melting points for different market demands.

How does It Work?

Before being fed into the crystallization tank, refined palm oil is heated to 60-70°C to melt existing crystals and convert it into a purely liquid state, after which it is pumped into the crystallization tank.

The crystallization tank is fitted with internal cooling coils. The oil is cooled to the pre-set temperature via cooling water supplied by the cooling tower, allowing solid fat to precipitate and form crystals (this temperature can be fully customized to your specific product requirements).

Once the target temperature is reached, the cooling process is stopped. Solid fat then continues to precipitate and form crystals under gentle agitation. Upon completion of the crystal growth process, the palm oil is transferred to the filtration stage for palm stearin and palm olein.

Key Features

(1) High-Efficiency Crystallization: Equipped with internal cooling coils and optimized agitation, the tank ensures uniform stearin crystallization and steady crystal growth.

(2) Precision Temperature Control: An automated control system delivers accurate temperature regulation and optimizes crystal size and uniformity.

(3) Energy-Saving Design: A cooling system with recyclable cooling water reduces energy consumption, greatly lowering your ongoing operating costs.

(4) Wide Application Versatility: Suitable for both palm oil fractionation and the dewaxing of sunflower oil, corn oil, rice bran oil, and other oils, it is also capable of producing palm oil fractions with different melting points.
