Coconut/Copra/Oil Seeds Mill Introduction
Copra oil expeller is a continuous oil press machine for once pressing of copra or the second pressing of pre-pressed copra cake in the oil production line to obtain oil. The operations from copra feeding, copra cooking, oil pressing and cake discharging are achieved automatically and continuously. Apart from copra, this oil press machine is also suitable for pressing other oilseeds such as peanut, sesame, sunflower seed, cottonseed, rapeseed, soybean, camellia seed, tung seed, rice bran, flaxseed, etc. Oil expeller is suitable for small and medium scale oil plants.

Features of Copra Oil Press
1. Rational structure, easy maintenance, high production efficiency, low residual oil rate
2. Main parts of the copra oil expeller adopt high-quality alloy steel and are hardened, sturdy and durable.
3. Oil press machine integrates the function of cooking and can adjust the moisture content and temperature of oilseeds to achieve better-pressing effect,
4. Automatic and continuous operation, convenient to manage, saving labor.

Structure &Working Principle of Copra Oil Press Machine
1. Copra oil press consists of feeding mechanism, worm shaft, bar cage, cake thickness adjusting mechanism, adjusting cooker and driving mechanism. The worm shaft of the oil making machine has seven sections of worms and six sections of intermediate collars sleeved on the shaft. The bar cage is composed of cage loading plate, cage bar, convex cage bar, the pressing plate, knife bar, spacer, special bolt, etc. The worm shaft and bar cage coordinate to form the barrel.
2. The knife bar which corresponds to the intermediate collar in position cooperates with the intermediate collar to turn the materials. When amounting the cage bars, the edge should be in the rotation direction of the worm shaft. Spacers are placed between the cage bars to form the oil flowing gap.
3. The materials from the feeding mechanism of the oil expeller enter the barrel continuously. The worm shaft rotates anticlockwise and pushes the materials forward. With the decrease of the barrel volume, the volume of the materials are compressed and the oil is pressed out and flows out through the gaps between the cage bars.
Operation of Oil Making Machine
After the adjusting cooker of the copra oil press is preheated, put the materials into the adjusting cooker till the discharge door at each layer closes automatically and then feed materials to the barrel. Feed a small amount at first and gradually increase. Spray the direct steam onto the materials if the cake is shapeless. Adjust the cake thickness after the barrel temperature rises. Cake with high oil content can be recooked and repressed by the oil making machine.

Advantages of Oil Processing Machine
1. The oil plant has low energy consumption and long service life.
2. The copra oil machine can minimize oil loss, increase the oil yield, improve product quality and improve the quality of oil and cake.
3. Continuous mechanization reduces human labor and labor costs.
4. Advanced dust removal system ensures the neat and clean of the workshop.
5. Adopts automatic welding technology, oil refinery machines look beautiful and clean.
