Non-transgenic soybean oil pressing device

Abstract

The invention discloses a non-transgenic soybean oil pressing device which comprises a body, a push rod and two sliding blocks. A first partition plate and a second partition plate are fixedly installed inside the body, the first partition plate is located below the second partition plate, and the first partition plate and the second partition plate sequentially divide the interior of the body into a first driving chamber, a pressing chamber and a second driving chamber. The lower end of the push rod stretches into the pressing chamber and is fixedly connected with a movable base. The two sliding blocks are installed at the bottom of the movable base in a sliding mode. A squeezing plate is fixedly installed at the lower ends of the sliding blocks. A fixed base is fixedly installed inside the pressing chamber and located below the squeezing plate. A movable sieve plate is arranged inside the pressing chamber and located below the fixed base. Since the squeezing plate which can be movedup and down and moved left and right is arranged, and the bottom of the squeezing plate is provided with crushing teeth for pressing oil from soybeans, the oil pressing effect is excellent.

Description

technical field [0001] The invention relates to the technical field of soybean processing, in particular to a non-transgenic soybean oil extraction device. Background technique [0002] Soybean oil is derived from soybean seeds and is the most produced oil in the world. There are many types of soybean oil. According to the processing method, it can be divided into pressed soybean oil and leached soybean oil; according to the type of soybean, it can be divided into soybean crude oil and genetically modified soybean oil. In terms of nutritional value, soybean oil contains 7-10% palmitic acid, 2-5% stearic acid, 1-3% arachidic acid, 22-30% oleic acid, 50-60% linoleic acid, and 5- linoleic acid. 9%. It is slightly soluble in ethanol, and can be dissolved in organic solvents such as acetone, toluene and xylene in a certain proportion.

AI Technical Summary

Problems solved by technology

[0003] Soybean belongs to low-oil crops. Generally, the content of soybean oil is in the range of 11-20%. In the prior art, a screw press is usually used to press soybeans. Sometimes bean dregs are mixed with bean dregs, so that the soybeans need to be purified again after pressing, which is complicated and inefficient; at the same time, when the screw press is in use, it is easy to produce cakes that are not smooth or not, which leads to the production of cakes after pressing. Soybean oil and bean dregs are difficult to get rid of, affecting the oil output and the reuse of the press
