What is the oil extraction process of rapeseed

Oil presses can be divided into screw presses and hydraulic oil presses according to their functions.

1, hydraulic oil press

Hydraulic oil press is a traditional small oil press, the production process is intermittent. The process is characterized by low operating technical requirements, high oil yield, good quality of gross oil, but the labor intensity is greater. Hydraulic oil press is suitable for occasions: small processing capacity, small workshop production, single daily processing capacity of about 1 ton.

2, screw oil press

Automatic screw oil press is a continuous operation of the oil press. Technical characteristics are: low operating requirements, high oil yield, the quality of oil compared to the hydraulic oil press, labor intensity is lower than the hydraulic oil press. Full-automatic screw oil press is suitable for occasions: small processing capacity, small workshop production, single machine daily processing capacity of about 2-8 tons.

3. Large and medium-sized screw oil presses

Screw oil presses are suitable for large and medium-sized, continuous, large-capacity oil factories. Technical characteristics are: continuous production, low labor intensity, high oil yield.

One, rapeseed oil extraction equipment production process:

1. Cold pressing process: rapeseed → cleaning and removal of impurities → cold pressing → cold pressed gross oil → coarse filtration → refining → cold pressed oil → rapeseed cake

2. Hot pressing process: rapeseed → cleaning and removal of impurities → steam frying → oil pressing → sedimentation → refining → tea oil; the main equipment components: elevator, clean-up sieve, steam frying pot, oil press, filter

Two, rapeseed oil refining equipment production process

Gross oil a alkali refining a decoloration a decolorization a deodorization a de-waxing workshop (or finished oil workshop)

The main equipment composition: refining tank, decolorization tank, deodorization tank, heat conduction oil furnace, filtration machine, etc.

Three, rapeseed oil de-waxing equipment technology

In the processing of fats and oils, through the winterization dewaxing process can be used to remove the oil. In the process of oil and grease, the wax inherent in the oil and grease can be separated from the oil and grease through the winterization and dewaxing process, which can enhance the nutritional value of the oil and grease, and improve the taste and quality of the oil and grease.

Main equipment components: freezers, filters, crystallization tanks, finished oil tanks, etc.

The cost of the equipment is related to the capacity, configuration, and the quality of the finished oil requirements, and can not be concluded;

This is the main equipment for the winterization process.
