Background

In the oil pressing process of the camellia oleifera fruits, the production of the tea oil in the traditional technology is that tea oil seeds are directly sent into pressing equipment to be pressed, so that the tea oil is produced. This method has the following drawbacks: the complete tea oil seed shell is hard, so that the service life of the squeezing equipment is influenced; tea seed particles are large and may clog machinery.

Most of the existing oil presses adopt a screw and a helical blade, and the space is reduced basically by uniformly increasing the diameter of the screw or/and reducing the pitch of the helical blade according to the principle that the space is gradually reduced to extrude oil in the conveying process. Although this type of method can achieve oil pressing, it has the disadvantages of unnecessary time consuming pressing and low oil pressing yield. The reason is that the camellia seeds are conveyed to an idle section for starting to press, namely, conveyed to an initial pressing process, and the camellia seeds cannot be pressed even if the space is reduced, because the space is remained. The prior art is a structure which is uniformly and slowly reduced and changed, and the design prolongs the production time, thereby reducing the squeezing efficiency; in the coining section, the diameter of the screw is gradually increased and the thread pitch is reduced in the structure in the prior art, although the space is reduced doubly, the coining time is greatly shortened by the design, tea seeds cannot be squeezed fully and squeezed sufficiently, the squeezing is not complete fully, and the oil yield is low.

Detailed Description

The invention is further described below with reference to the figures and examples.

Referring to fig. 1, the squeezing rod for increasing oil yield in this embodiment includes a rod body 1 and a helical blade 1a fixedly and continuously surrounding the rod body 1, wherein the rod body 1 is sequentially provided with a feeding section 11, a preliminary pressing section 12 and a finishing pressing section 13 along a rod length direction. The diameter of the rod body 1 in the feed section 11 is constant in this embodiment, but may not be constant in other embodiments. The feeding section 11 is mainly used for conveying materials, plays a role in bearing up and down, and then conveys the materials into the primary pressing section 12; the primary pressing section 12 mainly reduces the pressing space to play a transition role, and the structure of the embodiment can quickly finish the transition stage, thereby saving time and improving efficiency; the primary pressing section 12 can also perform primary pressing on the materials; the screw pitches of the feeding section 11, the primary pressing section 12 and the coining section 13 are respectively a first screw pitch 11a, a second screw pitch 12a and a third screw pitch 13a, the first screw pitch 11a is smaller than the third screw pitch 13a, in other words, the third screw pitch 13a of the coining section 13 is designed to be larger than the first screw pitch 11a, the traditional thinking and the conventional technical means are broken through, the structural design is opposite to the traditional structure, the change of the pressing space is an increasing trend relatively, but as the radial cross-sectional area of the rod body 1 from the primary pressing section 12 to the coining section 13 is gradually increased, and the increasing speed is gradually reduced, namely the radial cross-sectional area of the rod body 1 is always increased, which means that the change trend of the pressing space is always reduced. The third pitch 13a is thus only a restriction of the reduction in space, above the first pitch 11a, and the finishing section 13 is still in the press configuration which reduces the press space as a whole. In conclusion, the radial cross-sectional area of the rod body 1 is gradually increased, the first thread pitch 11a is smaller than the other feature of the third thread pitch 13a, the two features can generate offset matching, the total design can prolong the oil refining time, and the structure of the oil refining section 13 is prolonged, so that the oil refining is more sufficient, and the oil yield is effectively improved. The increasing rate of the radial cross-sectional area is smaller and smaller, the structural design enables the whole structure to be smooth in transition, and meanwhile, the blocking probability is reduced; this feature also indirectly extends the coining time further. Compared with the oil outlet section in the prior art, the structure in the prior art has the advantages that the oil outlet rate is low due to short oil squeezing time; on the other hand, the structure is fast in change and easy to block, and meanwhile, a large moment needs to be provided, and the requirement is high.

In this embodiment, better improvement lies in, in order to further reduce the time that the transition stage that the initial pressure section 12 carried the oil of exerting pressure from the non-pressure in the process of squeezing spent, improves and squeezes efficiency, second pitch 12a is less than first pitch 11a, and this structure can further dwindle the space that presses the frame 2 and squeeze the pole and enclose in the transportation process fast to shorten unnecessary time.

In some embodiments, the curves at both ends of the cross-sectional area of the rod body 1 in the rod length direction from the initial pressing section 12 can be parabolic curves, tangent function curves or inverse proportion function curves, and are obtained by copying mirror images after translation and/or rotation, or according to the characteristics: other similar curves of the characteristic that the radial cross-sectional area of the rod body 1 increases gradually from the initial pressing section 12 to the finishing pressing section 13, and the rate of increase becomes smaller and smaller. In this embodiment, a tangent function curve is preferred, where the function is y ═ tan x, and a part of the curve is selected, and then the tangent function curve is obtained by translating and/or rotating and then copying the mirror image. Referring to fig. 2, the inside of the cheek 2 corresponds to the asymptote.

In this embodiment, in order to further improve the pressing effect, the coining process is set to be longest for improving the oil yield, and the length of the feed section 11 and the length of the preliminary pressing section 12 are both shorter than the length of the coining section 13.
