Castor Oil Mill

Castor Oil Mill Introduction

Castor oil mill is used for pressing castor bean for oil. There are semi-automatic castor oil press and automatic castor oil press. The castor oil produced is used for industrial applications and the residual oil rate is 6-8%. Castor oil machine features convenient operation, easy maintenance, and stable performance. Adopt helical gear design, castor oil expeller has high transmission efficiency, saving energy. Having wide applications, castor oil extraction machine can also process peanut, rapeseed, soybean, sunflower seed, camellia seed, cottonseed, copra, palm kernel, corn germ, sesame, walnut, etc. Castor bean shelling machine is available for shelling the castor seeds.

Features of Semi-automatic Castor Oil Press

Semi-automatic castor oil machine is suitable for specialized households, small and medium oil processing plant as well as pre-pressing in solvent extraction plant. 
2. Simple structure, strong applicability, easy operation, suitable for continuous operation.
3. Small castor oil expeller adopts reasonable barrel design, having high capacity and high oil yield.
4. Wearing parts adopt high-quality steel with carburizing heat treatment, having a long service life.

Structure and Working Principle of Semi-automatic Castor Oil Expeller

Semi-automatic castor oil press machine consists of feed hopper, gearbox, barrel, worm and frame.
Theflakesenter the barrel through the feed hopper. With the rotating of the worm shaft, the materials are pushed forward continually. The increasing of bottom diameter of the worm causes the reducing of the volume within the barrel. The pressure increases and castor oil is squeezed out. Meanwhile, the movement of flakes results in the friction between the flakes, worm, and barrel, producing a large amount of heat. The temperature of the flakes increases, increasing the plasticity of castor seeds and reducing the viscosity of the oil, which is good for the outflow of oil and increases the oil yield of the castor oil extraction machine.
