Description

A kind of double helix juice extractor

Technical field

The present invention relates to food processing equipment technical field, specifically, relate to a kind of double helix juice extractor.

Background technology

Enter after 21 century, along with saturated gradually with marketing fresh market of increasing substantially of China's fruits output, " selling fruit difficult " grows in intensity.In addition, due to the enhancing of China's economic strength and the raising of living standards of the people, fruit juice processing industry enters again a new developing period.Juice extractor is the important component part of fruit trade.Therefore, imperative to the research of juice extractor equipment.Main spiral juice extractor is single-screw juice extractor in the market, single-screw convey materials ability is strong, but its lead angle (or claiming helical angle) fluctuation little and extrusion capacity is larger, this has just caused its convey materials few, crushing juice rate is low and production capacity is low, is difficult to meet the large batch of production requirement of garden stuff processing factory.Patent CN 200780001269.X discloses a kind of juice extractor, in order to improve mouthfeel, keeps the genuineness of fruits and vegetables, and what it adopted is screw-rod structure, but convey materials is few, is applicable to family expenses; Patent CN 201110030640.3 discloses a kind of juice extractor, and it adopts drum-type squeezing fruit, has solved automatic discharge problem, but the material of carrying when it squeezes is few.

technical scheme

For the above-mentioned problems in the prior art, the invention provides the double helix juice extractor that a kind of convey materials is many, production capacity is high and crushing juice rate is high.

In order to address the above problem, the technical solution adopted in the present invention is as follows:

A kind of double helix juice extractor, is characterized in that: comprise driving motor (1), bearing block (2), main shaft (3), feed hopper (4), double helix (5), front bearing (6), skeleton (7), screen pack (9), rear support (10), pressure regulation head (11), scum board (12), go out juice bucket (13), dirt-excluding bucket (14), cylinder (15), frame (16) and belt pulley (17), described driving motor (1) is fixed on an end of frame (16), belt pulley (17) is connected with driving motor (1), one end of main shaft (3) is connected with belt pulley (17), the side of the other end of main shaft (3) is provided with cylinder (15), main shaft (3) is by the bearings in the bearing block (2) and the rear support (10) that are fixed in frame (16), described double helix (5) is fixed on main shaft (3), in the time that main shaft (3) rotates, can drive double helix (5) to rotate together, spiral on double helix (5) increases gradually along footpath at the bottom of material slag Way out and pitch reduces gradually, described pressure regulation head (11) is connected with cylinder, the cutaway view of pressure regulation head (11) is taper, a pressure regulation horizontal direction moves, described scum board (12) is fixed on main shaft (3) with double helix (5) is gapped, rotate with main shaft (5), described dirt-excluding bucket (14) is located at below rear support (10), between described double helix (5) and pressure regulation head (11), there is the gap of slagging tap, control the size in the gap of slagging tap by cylinder (15) promotion pressure regulation head (11), in the time that the pomace of pie is discharged, scrape under the effect of beating and break into clastic in the rotation of scum board, then discharge from dirt-excluding bucket (14).

Described feed hopper (4) be located at front bearing (6) above, facilitate material to enter in the cavity of double helix (5), described skeleton (7) is fixed on screen pack (9) centre of front bearing (6) and rear support (10), the outside of screen pack (9) is provided with lining net (8), described go out juice bucket (13) be located at below skeleton (7), when in the time squeezing the juice, the juice flowing out by screen pack can flow directly into out in juice bucket.

The course of work of double helix juice extractor:

Fruit raw material (broken pulp, fruit juice and pericarp) enter in double helix (5) by feed hopper (4), because the spiral on double helix (5) increases gradually along footpath at the bottom of material slag Way out, pitch reduces gradually, in the time that material is advanced by double helix (5), helical cavity volume dwindles, form the squeezing to material, the juice of its squeezing flows into going out in juice bucket (13) of bottom by screen pack (9) and discharges, pomace is scraped under the effect of beating and breaks into clastic in the rotation of scum board (12), enter dirt-excluding bucket (14) by the space of slagging tap forming between double helix (5) and pressure regulation head (11), discharge from dirt-excluding bucket (14), reach juice and the automatic object separating of slag.Pressure regulation head (11) along continuous straight runs moves and is directly subject to baric systerm control, by the admission pressure of adjusting cylinders (15), adjusts the resistance of deslagging, can adjust crushing juice rate according to different material.

Beneficial effect: the present invention adopts double helix, double helix conveying capacity is larger than single-screw, because double-helical lead angle (or claiming helical angle) is higher than single-screw, in other words, is both and rotates a circle, and double-helical conveying capacity is larger than single-screw.Under same rotating speed, because double helix lead angle (or claiming helical angle) is higher than single-screw, and the contact area on material and screw channel surface is large, thereby conveying capacity is large, and extrusion capacity is more stable, has improved the quality of crushing juice rate and product.
