Squeezing rod and camellia oleifera fruit squeezing equipment for improving oil extraction rate

Abstract

The invention discloses a squeezing rod and camellia oleifera fruit squeezing equipment for improving the oil extraction rate. The squeezing rod comprises a rod body and helical blades, wherein the helical blades are fixedly arranged on the rod body in an encircling manner; the rod body is sequentially provided with a feeding section, a primary squeezing section and a fine squeezing section in thelength direction of the squeezing rod; the screw pitch of the feeding section, the primary squeezing section and the fine squeezing section is respectively a first screw pitch, a second screw pitch and a third screw pitch; the first screw pitch is smaller than the third screw pitch; the radial cross section area, from the primary squeezing section to the end of the fine squeezing section, of therod body is gradually increased; and the increment rate is smaller and smaller. The camellia oleifera fruit squeezing equipment comprises the squeezing rod and further comprises a squeezing chamber; the squeezing rod is arranged inside the squeezing chamber; one end, extending out of the squeezing chamber, of the rod body is fixedly connected with a driven gear; the other end of the squeezing chamber is fixedly connected with an end cover; the squeezing chamber is further provided with a condensation system; the upper part, far away from the end cover, of the squeezing chamber is provided witha feeding opening; and the feeding opening is connected with a crushing part. The squeezing rod disclosed by the invention improves the oil extraction rate and achieves relatively high squeezing efficiency; and the camellia oleifera fruit squeezing equipment is high in oil extraction rate, high in durability, long in service life and high in 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...

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
