Description

Technical Field

[0001] The invention relates to the field of vegetable oil, in particular to an extraction device for vegetable oil production. Background Art

[0002] Vegetable oil is a compound formed by the reaction of higher fatty acids and glycerol. It is widely distributed in nature and is an oil obtained from the fruits, seeds, and germs of plants, such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc.

[0003] The Chinese patent application number is CN202010893116.8, which discloses a heavy hammer recovery type vegetable oil pressing device, including a rotating barrel, an annular feed trough and an annular oil receiving trough, the inner ring of the annular feed trough is fixedly connected to a circular cover body, the semicircular flat block of the circular cover body is riveted to a suspension arm, the suspension arm is riveted to a swing arm, the two ends of the swing arm are riveted to a Y-shaped support rod, and the Y-shaped support rod is connected to a roller shaft, a rolling roller and a discharge bucket; the rotating barrel is provided with a steam chamber and a fixed oil outlet pipe, and the fixed oil outlet pipe is connected to the rotating oil outlet pipe through a first pipe clamp; a rotating shaft and a low-speed motor are provided at the bottom of the rotating barrel, and a gear track is provided at the top of the rotating barrel; the fixed discharge pipe of the annular feed trough is connected to the rotating discharge pipe through a second pipe clamp. The present invention adopts a pipe clamp flange connection structure for the first time to realize intermittent discharge; the present invention adopts a seesaw structure, and uses intermittent discharge to cause the rolling roller to rise and fall alternately, completing the heavy hammer recovery type grinding and oil pressing process; the structure and process of the present invention are relatively novel, and it is used for the primary oil pressing material residue produced by the existing oil pressing process, and the secondary oil pressing efficiency is relatively high.

[0004] In the existing pressing device, after strong squeezing in one direction, the compressed plant fruits, seeds, and germs form a ball, thereby blocking the internal plant fruits, seeds, and germs from breaking and flowing out of the vegetable oil. The vegetable oil can only flow out step by step from the outer surface and then the plant fruits, seeds, and germs in the internal position break and flow out of the vegetable oil. At the same time, the crushed plant fruits, seeds, and germs easily block the through holes for the flow of vegetable oil, resulting in reduced oil output efficiency. Summary of the invention
