Description

Juicing equipment

technical field

The invention relates to fruit and vegetable processing equipment, in particular to a juice extracting equipment.

Background technique

Grape is the fruit with the most complex iron elements among summer fruits, and it is a nutritious food for anemia patients. At the same time, the vitamin content in grapes is also very high. According to research, every 100 grams of grapes contains 50 international units of vitamin A, 100 international units of vitamin C, and 10 international units of vitamin B2. Eating grapes can help strengthen your body and improve your ability to resist diseases. immunity. The juice extracted from grape pulp is grape juice, which also has rich nutritional and economic value. Usually, grape juice is often used to make wine, brandy or whiskey after fermentation.

In the production of traditional grape juice, usually choose grapes with large grains, strong color, full maturity, and no pests and diseases, wash them with clean water, remove the fruit stems, put them in a clean aluminum pot, pinch them one by one by hand or crush them with a flat-bottomed teapot , Then pour the minced pulp in the pot into the laid gauze to filter, and squeeze it by hand to get the juice. The hand-squeezing method not only has slow processing speed, poor juice extraction effect, incomplete juice pressing, but also unsightly, affects hygiene, and even causes grape juice to be infected by miscellaneous bacteria, which greatly affects the quality of winemaking. Moreover, the extraction of fruit juice by the existing juice extractor is insufficient, resulting in waste of fruit juice.

Fig. 2 is a schematic structural view of the side wall of the juice extractor according to the present invention.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

As shown in Fig. 1 and Fig. 2, the present invention provides a juice extracting device, comprising: a juice extracting cylinder 1, a rubber layer 8 is arranged on its inner periphery, and the rubber layer 8 has a helical tooth groove 2; Shaft 3, which is vertically arranged in the juice extraction cylinder, and the juice extraction shaft is connected to a motor, the outer peripheral portion of the juice extraction shaft has helical teeth 4, and the helical teeth extend to the helical In the groove, and there is a gap of 0.2 ~ 0.4mm between the two side walls of the helical tooth and the two sides of the helical groove, the outer edge of the helical tooth and the edge of the helical groove The bottom groove wall retains a gap of 0.1 mm; the juice receiving cylinder 7, which is arranged below the juice squeezing cylinder; the filter screen, which is arranged between the juice squeezing cylinder and the described juice collecting cylinder; the filter screen It is in the shape of an inverted cone, the lower end of the filter screen is platform-shaped, the lower end of the juice extraction shaft is located above the lower end of the filter screen, and the outer circumference of the lower end of the juice extraction shaft is in contact with the filter screen. An annular inlet is formed between the circumferential side walls of the net; the outer sleeve 10 is sleeved on the outside of the juice extraction cylinder, and the lower part of the outer sleeve communicates with the juice collection cylinder, and the juice extraction The side wall of the cylinder is evenly distributed with through holes, the diameter of the through holes 11 is 0.1 mm, and the through holes connect the gap between the helical teeth and the helical grooves with the outer sleeve; Wherein, the motor drives the juice extraction shaft to rotate.

When in use, the fruit is loaded into the juice extractor from the top of the juice extractor, and the juice extractor shaft rotates under the drive of the motor, and the fruit enters into the helical teeth and the helical groove, and is inserted between the helical teeth and the helical groove. Crushing under extrusion, the fruit juice is collected into the juice collection cylinder through the filter screen, and the pomace is left on the filter screen. The helical groove is formed on the rubber layer. When the fruit is squeezed into the space between the helical teeth and the helical groove, the rubber layer can be deformed to ensure that the fruit can pass through the space and gradually move downward. The invention can fully squeeze the fruit and improve the juice collection rate.

The filter screen is in the shape of an inverted cone, that is, the circumferential side wall of the filter screen is inclined downward, so that the pomace is easy to slide down along the filter screen, and the pomace falls into the lower end of the filter screen, which will not affect the juice from the spiral. outflow from the slot. Moreover, the lower end of the juice extraction shaft actually forms a relatively small space 9 with the lower end of the filter screen, and an annular inlet is formed between the outer circumference of the lower end of the juice extraction shaft and the circumferential side wall of the filter screen, and the pomace passes through The annular inlet enters into the above-mentioned space, and when more pomace falls into the space, the lower end of the juice extraction shaft will also squeeze the pomace, so that the juice is further released from the pomace, and the The design can prevent the squeezed juice from being blocked by the pomace in the process of flowing downward, thereby affecting the recovery rate of the juice.

During the extrusion process, a part of the juice enters the outer sleeve through the through hole, and then flows into the juice collection cylinder through the outer sleeve, while the other part of the juice flows downwards and flows into the juice collection cylinder through the filter screen. And since it may be blocked by the pomace when it flows downward, and the pomace itself will also carry part of the juice, therefore, providing two paths to discharge the juice is helpful to increase the recovery rate of the juice.

Preferably, in the juice extracting device, protrusions are evenly distributed on the groove wall of the spiral groove. The protrusion is more conducive to fully squeezing the fruit, so that the juice can be fully released.

Preferably, in the juice extraction device, the juice extraction cylinder is cylindrical.

Preferably, in the juice extraction device, the upper part of the juice extraction shaft passes through the upper end of the juice extraction cylinder and is connected to the motor.

Preferably, in the juice extracting device, the lower end of the juice extracting cylinder has an inwardly protruding ring-shaped flange, and the upper edge of the filter screen is clamped on the ring-shaped flange.

The filter screen can be removed from the annular clamping edge for easy cleaning; when the filter screen is damaged, it is also easy to replace.

Preferably, in the juice extracting device, the filter includes an upper filter mesh 5 and a lower filter mesh 6, and there is a gap of 3 to 5 cm between the upper filter mesh and the lower filter mesh. Clearance.

In order to fully filter and avoid the filter from being blocked, a double-layer filter structure is also designed, that is, the filter includes an upper filter mesh and a lower filter mesh, and there is a certain gap between the upper filter mesh and the lower filter mesh. The pomace stays on the upper filter mesh, and a part of the pomace stays between the upper filter mesh and the lower filter mesh.

Although the embodiment of the present invention has been disclosed as above, it is not limited to the use listed in the specification and implementation, it can be applied to various fields suitable for the present invention, and it can be easily understood by those skilled in the art Therefore, the invention is not limited to the specific details and examples shown and described herein without departing from the general concept defined by the claims and their equivalents.
