Multi-cylinder circulating pressing method of rapeseed oil

Abstract

The invention provides a multi-cylinder circulating pressing method of rapeseed oil. The method comprises the following steps: a user places steamed/fried oil materials into a feeding mechanism, a rotary driving mechanism drives oil pressing cylinders to do 60 DEG clockwise step-by-step rotary motion around the axis of the oil pressing cylinders around a middle barrel, and when each oil pressing cylinder rotates to be aligned to and communicated with a feeding opening, the feeding mechanism conveys the oil material in the feeding mechanism into the oil pressing cylinder; then, when each oil pressing cylinder rotates to be aligned to and communicated with a plunger opening, a pressing driving mechanism drives a pressing rod to be inserted into the oil pressing cylinder from the plunger opening and extrudes and presses oil in the oil pressing cylinder; then, the oil material is converted into oil and oil residues, and the oil is discharged outwards through an oil discharging pipe; and finally, when each oil pressing cylinder rotates to be aligned to and communicated with a residue discharging opening, a residue discharging driving mechanism drives a residue discharging block to movevertically downwards and slide into the residue discharging opening from the second opening of the oil pressing cylinder, and the oil residues are ejected outwards from the residue discharging opening, fall into the residue discharging pipe and then are discharged outwards from the residue discharging pipe.

Description

technical field [0001] The invention relates to an oil press, in particular to a multi-barrel circulation extraction method for rapeseed oil. Background technique [0002] The intake of oil is essential for the human body. Whether it is vegetable oil or animal oil, it has a non-negligible effect on the health of the human body. The methods of extracting oil from plants can be roughly divided into two categories, one is physical pressing, the other The second is the chemical leaching method. The working principle of the oil press is to use the physical pressing method, that is, the oil press uses the mechanical external force to activate the oil molecules by increasing the temperature and squeeze the oil out of the oil. The edible oil extracted by this method is pure natural, pollution-free, and is deeply loved by people. However, there is a problem in the existing oil press tablet. Operation is time-consuming and labor-intensive, and the degree of automation is low. In orde...

[0002] The intake of oil is essential for the human body. Whether it is vegetable oil or animal oil, it has a non-negligible effect on the health of the human body. The methods of extracting oil from plants can be roughly divided into two categories, one is physical pressing, the other The second is the chemical leaching method. The working principle of the oil press is to use the physical pressing method, that is, the oil press uses the mechanical external force to activate the oil molecules by increasing the temperature and squeeze the oil out of the oil. The edible oil extracted by this method is pure natural, pollution-free, and is deeply loved by people. However, there is a problem in the existing oil press tablet. Operation is time-consuming and labor-intensive, and the degree of automation is low. In order to overcome the above-mentioned disadvantages, it is necessary to provide a physical oil extraction method of a vertical rotary circulation oil press with ingenious structure, simple principle, convenient operation, high automation, and high oil extraction efficiency. method
