Canola Oil Processing Plant

Canola Oil Processing Plant Introduction

Canola oil processing plant is a small scale plant to extract canola oil by pressing method. By using the canola oil processing equipment, the rapeseeds are cleaned, roasted, screw pressed and refined. The rapeseed oil press machine adopted has the functions of automatic barrel heating, pressing and oil filtering. The feeder equipped helps increase production efficiency and save labor. The refined rapeseed oil can be filled into bottles for sale. Meanwhile, we provide canola oil extraction plant which extracts oil from canola cake by the solvent for medium and large-scale oil production. Our canola oil processing equipment can be customized according to your requirement.

Features of Canola Oil Processing Equipment

1. Small capacity, low investment, simple process, easy to operate, low labor intensity. 2. The rapeseed oil press machine integrates the functions of pressing and filtering. 3. Canola oil extraction plant is equipped with refining equipment to produce high-quality healthy oil. 4. Suitable for small oil mill or small rapeseed oil processing plant. 5. The oil cake produced can be used for solvent extraction. 6. Canola oil processing equipment can be customized according to your requirement.

The Process of Canola Oil Processing Plant

1. Canola Cleaning

The cleaning process can reduce the abrasion of equipment, ensure safe operation, reduce oil loss, increase oil yield and improve the quality of oil and oil cake. Canola oil extraction plant adopts rapeseed selector, gravity destoner, and magnetic separator to remove the clay, stone, metal and other impurities in the rapeseeds.

2. Canola Roasting

Adopt rotary roaster or flat bottom roaster for rapeseeds roasting to achieve the desired temperature and moisture. The flat bottom roaster adopts conduction oil as the heat source and stirs the materials with the mixing blade. The rotary roaster has the rapeseeds turned within the rotating drum for uniform heating.

3. Canola Oil Press Machine

With the aid of feeder, the roasted rapeseeds enter the canola oil press machine. The worm rotates along with the main shaft to push the materials forward. With the reducing of the volume of the pressing chamber, the pressure within the chamber increases gradually. Rapeseed oil press machine is equipped with the automatic barrel heating system. Meanwhile, the friction force produces heat. The cells of the materials are destroyed and the oil flows out. When the oil flows onto the filtering barrel, by the vacuum pump, the oil is pumped into the barrel and the residues are left on the filter cloth, thus the pure oil is obtained.

4. Canola Oil Refining

1)Degumming

Degumming is to remove the phospholipids in the crude rapeseed oil. The crude oil is preheated and phosphoric acid is added.

2)Alkali refining

Alkali refining is to remove the free fatty acids in the crude oil. Alkali acid is added to reacts with free fatty acid. When the soapstocks precipitate obviously, stop stirring and settle for several hours. Then remove the soapstocks. Preheat the clean oil and add hot saline-alkaline water. Settle and discharge the wastewater. Wash with hot water for several times.

3)Decolorization

Decolorization is to remove the pigments in the canola oil. Pump the oil into the decolorization tank and dehydrate under vacuum. Add bleaching clay and stir for 20 minutes. Then the oil is cooled and filtered.

4)Deodorization

Deodorization is to remove the odor substances in the oil. The decolorized oil is pumped into the deodorization tank for vacuum deodorization by steam distillation. The oil is then cooled and filtered.
