JPH06245746A - Squeezing of vegetable and apparatus therefor - Google Patents

Abstract

PURPOSE:To obtain a method and apparatus for squeezing vegetable juice and capable of separating exclusively vegetable juice from the residue at high speed in high yield without destroying the nutrient component in the vegetable. CONSTITUTION:A vegetable used as the raw material is roughly crushed with a screw press provided with a roller having a particular shape and the roughly crushed vegetable is pressed and squeezed using the high pressure generated in a hydraulic press. Exclusively the vegetable juice can be separated in high yield without destroying the nutrient component in the vegetable by the use of the above two-stage squeezing process.

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting juice from plants such as vegetables, fruits and medicinal materials and a device therefor, and more particularly to a two-stage juice extracting method combining a screw press and a hydraulic press and a device therefor. It is about.

[0002]

BACKGROUND ART Various vegetables such as wild grass, root vegetables, fruits and leaves contain various nutrients necessary to balance the nutrition of the body, and they have been popular as healthy juice for a long time. Various juicers for making juice are commercially available. In addition to vitamins and calcium contained in vegetable and fruit juices, folic acid is contained particularly in the leaves of green-yellow vegetables, which has the effect of helping the absorption of vitamins and minerals. However, folic acid has a fragile property, and a large part is destroyed by a high-speed rotating electric juicer, and its effect is not exhibited. The handy juicer is highly evaluated for its effect of keeping folic acid without being destroyed by about 3 times as much as that of the electric juicer. Since it was collected, the juice was mixed with vegetable waste, and it was difficult to make it into pure juice, which caused drawbacks such as poor mouthfeel and difficulty in drinking. Handy juicer requires a lot of effort to obtain a given amount of juice due to low yield Therefore, in electric, development juicer that same effect as handy juicer is obtained it has been desired.

[0003]

For this reason, the applicant has already proposed, as Japanese Patent Application Nos. 220122 and 2-102047, a juicer in which a crushing roller and a pressing screw are combined. Depending on the type, there is a problem that it is difficult to automatically add the raw materials, and the yield is significantly deteriorated. Therefore, an object of the present invention is to provide a plant squeezing method and an apparatus therefor, which is an electric device that can be automatically charged regardless of the type of raw material, and that can obtain juice obtained by completely separating the obtained juice from the residue. That is.

[0004]

In the present invention, a screw press equipped with a roller having a special shape is used to roughly crush the plant raw material fed from the raw material vegetable feeding port, and the raw material crushed by the screw press is used. The screw press used in the present invention together with the hydraulic press is introduced into the hydraulic press for pressure squeezing, and the screw press is of the extruder type, and has a large number of cuts in a part of the thread portion of the roller, and thereby the plant material. Regardless of the type, it is extremely easy to introduce the raw material, and the hydraulic press is a cylindrical press having an inlet on the lower side and an outlet on the upper side, and is arranged vertically or obliquely. The two-stage pressing using this cylindrical hydraulic press combines the screw press with the high pressure of the hydraulic press to completely separate the plant sap and residue, thereby increasing
It is possible to obtain a sap with a high yield and obtain a high-quality plant sap without destroying various nutrients.

EXAMPLES Examples of the present invention will be shown below. Example 1 390 g of carrot (crushed amount of 430 g, water of 70 g) was pressed by the method of the present invention to obtain 320 g of juice and 70 g of residue. This was a yield of 74%, and 226 g of juice obtained by treating the same material and the same amount by the conventional method, 165 g of residue
It was confirmed that the yield was remarkably improved as compared with (yield 54%).

Example 2 Carrot 430 g (crushed amount 490 g, water 70 g) was squeezed by the method of the present invention, then 360 g of juice and 110 g of residue.
Got This is a yield of 73%, and the same amount, 290 g of sap obtained by treating the same material by a conventional method, 170 residue
The yield was significantly higher than that of g (59% yield).

[0007]

EFFECTS OF THE INVENTION According to the present invention, by using a screw roller having a special shape, it is possible not only to feed a raw material by a machine regardless of the type of raw material plant when squeezing a plant, but also to add juice from a high pressure hydraulic press. Complete collection can lead to a breakthrough improvement in sap product yield.
