Description

A cold pressed oil mold

technical field

The invention relates to the field of agricultural product processing, in particular to a cold-pressed oil mold.

Background technique

Camellia oleifera is a unique oil species in China, and camellia oil is a high-quality edible oil unique to my country. The grade is comparable to that of olive oil, and its unsaturated fatty acid content is as high as 90%. Camellia oil is good in color and flavor, rich in nutrition, and has the effects of lowering blood pressure, blood lipids and softening blood vessels. Long-term consumption can make people's skin tender and moist, hair black and shiny, and improve human immunity, which has extremely high beauty and health care values.

The traditional cold pressing tools for camellia oleifera seeds have low efficiency, quality and output, and it is difficult to meet the needs of the market.

Contents of the invention

Based on the deficiencies of the prior art, the problem to be solved by the present invention is to provide a cold-pressed oil mold, which can cold-press tea oil from tea seeds with high efficiency, high quality and high yield.

In order to solve the above-mentioned technical problems, the present invention provides a cold-pressed oil mold, which includes an inner squeeze barrel and an outer squeeze barrel with oil outlet holes on the side wall, the inner squeeze barrel and the outer squeeze barrel are coaxial; A cavity is formed between the outer wall of the inner squeeze barrel and the inner wall of the outer squeeze barrel; the cavity is provided with a squeezing mechanism that can rotate together with the inner squeeze barrel and the outer squeeze barrel and can run axially along the inner squeeze barrel; The inner squeezing barrel is provided with a feeding device that enables the material to be squeezed to enter the cavity without leaking out during squeezing.

As a further improvement of the above technical solution:

One end of the outer squeeze barrel is fixed with a fixed ring; the squeezing mechanism includes: a backing plate located at the front end of the cavity and limited by the fixed ring, a push plate located at the rear end of the cavity, and a push plate between the back plate and the push plate. At least one set of inner squeezers in said cavity between the plates.

The inner squeezer includes a pressing plate and the top plate arranged on the front side of the pressing plate, there is a gap between the top plate and the pressing plate to form a small horizontal oil storage space; and the surface of the top plate and the pressing plate is uniform Through holes are distributed for horizontal oil extraction.

The inner squeezer also includes a rib plate vertically connected to the squeeze plate, which can cut the squeezed material into two halves for easy cleaning.

There are two ribs and they are located on the same plane, which is a preferred solution.

There are two guide grooves and outer guide rails, and they are located on the same diameter of the radial section of the cylinder where they are located, which is a preferred solution.

The feeding device includes a feed and oil outlet pipe that fits into the inner squeeze barrel and has a sealed front end; the outer wall of the feed and oil outlet pipe is provided with at least two inner guide rails in the axial direction, and the inner wall of the inner squeeze barrel is provided with One-to-one correspondence with the inner guide rails, wide guide grooves with the same length; the inner guide rails are placed in the wide guide grooves, so that the feed and oil outlet pipes can rotate together with the inner squeeze cylinder and pass through the wide guide grooves The groove rotates at a certain angle relative to the inner squeeze barrel; the side wall of the inner squeeze barrel is provided with an outer feed hole, an outer oil outlet hole and an inner cylinder pin hole; the side wall of the feed oil outlet pipe is provided with an inner feed hole, an inner The oil outlet hole and the first pin hole and the second pin hole; when the feed oil outlet pipe rotates to the position corresponding to the first pin hole and the inner barrel pin hole relative to the inner cylinder, the outer feed hole and the inner cylinder pin hole The inner feed hole is completely connected through, and the inner oil outlet hole and the outer oil outlet hole are completely staggered; when the feed oil outlet pipe rotates to the position corresponding to the second pin hole and the inner cylinder pin hole relative to the inner cylinder, The outer feed hole and the inner feed hole are completely staggered, and the inner oil outlet hole and the outer oil outlet hole are completely connected through each other.

There are two inner guide rails, which are located on the same diameter of the radial section of the feed and oil outlet pipes, which is a preferred solution.

The rear end of the feed and oil outlet pipe is provided with a hand wheel, which is convenient for manually rotating the feed and oil outlet tube.

The process of making and using the present invention is as follows: first rotate the feed oil outlet pipe 7, so that the inner feed hole 70 on the feed oil outlet pipe 7 and the outer feed hole 60 on the inner squeeze barrel 6 completely correspond to each other. The pin hole corresponds to the pin hole of the inner cylinder, and is inserted into the first set of bolts to fix; then the compressed hot air feeds the material from the end of the feed and oil outlet pipe 7 with the hand wheel 10, and passes through the inner feed hole 70 and the outer feed hole 60 in turn Enter into the cavity between the outer squeeze barrel 3 and the inner squeeze barrel 6, and surround the inner squeeze barrel 6; when the feeding is finished, turn the feeding and discharging oil pipe 7 to stagger the above-mentioned feeding holes, so that the feeding and discharging The inner oil outlet hole 71 on the oil pipe 7 is completely corresponding to the outer oil outlet hole 61 on the inner squeeze cylinder 6. At this time, the second pin hole corresponds to the inner cylinder pin hole, and the second set of bolts is inserted to fix it; then the pressing force moves from right to Squeeze the push plate 9 on the left, push multiple groups of rib plates 8, squeeze plate 5 and top plate 4 in sequence, reduce the cavity volume, and form a squeeze on the material inside; after a period of time, the inner squeeze cylinder 6 drives through the groove structure The entire mold rotates for a certain period of time to increase the oil output. After being pressed, the material is extruded into a cake shape with a hole in the center, and the pressed residue cake is divided into two halves by the rib plate 8, and the oil flows out from the oil outlet pipe 7 and the oil outlet hole on the side wall of the outer pressing cylinder 3. Finally, the thrust squeezes the backing plate 2 from left to right, and pushes the top plate 4, the press plate 5, the rib plate 8 and the rightmost push plate 9 to separate from the outer press cylinder 3 together, and the pressed slag cake divided into two halves breaks away from the mold and enters collection box. Afterwards, the mold can be installed and reset for the next pressing process.

The present invention compresses hot air, high pressure, and rotates to maximize the oil in camellia oleifera seeds, and has a simple structure, high efficiency, safety and sanitation, because the temperature of the hot air is not too high, so this kind of pressing still belongs to cold pressing.
