A pressing rod and camellia oleifera fruit pressing equipment for improving oil yield

Abstract

The invention discloses a pressing rod and camellia oleifera fruit pressing equipment for increasing the oil yield. The pressing rod includes a rod body and a helical blade fixedly surrounding the rod body. The rod body is sequentially provided with a feeding section, an initial pressing section and a finishing Pressure section; the pitches of feed section, initial pressure section and fine pressure section are the first pitch, second pitch and third pitch respectively, and the first pitch is less than the third pitch; the rod body starts from the initial pressure section to the end of the fine pressure section The radial cross-sectional area increases gradually, and the rate of increase becomes smaller and smaller. Camellia oleifera fruit pressing equipment includes the above-mentioned pressing rod, and also includes a pressing rod. The pressing rod is rotatably arranged in the pressing rod. One end of the rod extending out of the squeezing rod is fixedly connected with a driven gear, and the other end of the squeezing rod is fixedly connected with an end cover; There is also a condensation system; the upper part of the squeezer away from the end cover is provided with a feed port, and the feed port is connected with a crushing part. The pressing rod of the present invention improves the oil yield and has high pressing efficiency; the pressing equipment has high oil yield, strong durability, long service life and high production efficiency.

Description

technical field [0001] The invention relates to the field of oil pressing machinery, in particular to a pressing rod and camellia oleifera fruit pressing equipment for improving the oil yield. Background technique [0002] In the oil extraction process of camellia oleifera, the production of tea oil in traditional technology is to directly send tea oil seeds into the pressing equipment, and press the tea oil seeds to produce camellia oil. This method has the following defects: the complete camellia oil seed shell is relatively hard, which will affect the service life of the pressing equipment; the tea oil seed particles are relatively large, which may block the machine. [0003] Most of the existing oil presses use screws and helical blades. The principle of squeezing out oil during the conveying process is through gradually reducing the space. Basically, the space is reduced by uniformly increasing the diameter of the screw rod or / and reducing the pitch of the helical blade...

Problems solved by technology

This method has the following defects: the complete camellia oil seed shell is relatively hard, which will affect the service life of the pressing equipment; the tea oil seed particles are large, which may block the machinery

The existing technology is a structure that shrinks and changes uniformly and slowly. This design prolongs the production time, thereby reducing the pressing efficiency; while in the fine pressing section, the existing technology structure is to gradually increase the screw diameter and reduce the pitch, although it is a double reduction. space, but this design will greatly shorten the fine pressing time, and the tea oil seeds will not be fully squeezed and squeezed enough time, so that the pressing is not sufficient and incomplete, resulting in a low oil yield
