The invention relates to food, mainly the canning industry, and can be used for the production of juices from fruits and vegetables in your home or in small workshops in the processing of crops grown on private land or farms.

The known device for extracting juice ikih devices are widely used cone screw nozzle for manual and electric meat grinder or food processor. Under this scheme, with attached juicer auger type directly on the feed auger grinder wear pressing tapered screw extractor set the filter mesh and assemble design. Two auger collected sequentially in a single line, in the process, just press products, feeding them to the exit, so fruits and vegetables should be pre-cut into thin lengthwise slices or cubes with sides not more than 10 mm, and solid fruits and vegetables pre-chopped grated (see household meat Grinder manual MA-p-5. Operation manual OM JSC Pertignas", 1992, S. 6-7. Console-juicer).

When versatility and good performance of such additional devices-juicers, the disadvantage of this construction and arrangement, good showing himself in the processing of berries is that they are not encouraged to recycle hard vegetables such as raw carrots, beets and radishes and solid varieties of fruits, as apples and tomatoes before pressing, you first need to grind that leads to oxidation of the raw materials in the air and reduce the quality of the juice. In addition, preliminary preparation of raw materials (grinding) requires additionally the tvii with GOST 26499-85 ranges from 300 to 700 watts, and when the pressing screw extractor is not fully used.

It is also known device (see patent Germany DE 2550021 A, A 23 N 1/00, 7.07.77) version No. 1 shown in Fig. 1 with the cross sections in Fig. 3, includes a feed auger, chopper device and pressing screw is placed in the casing with perforations for discharge of the juice. In this device for extracting the juice supply of raw materials, grinding of raw materials and the extraction of the juice is carried out sequentially in a single operation. The design feature of the device according to DE 2550021 is that the feed screw disposed vertically and eccentric to the axis of rotation. Screw in the lower part (at the outlet of the auger) teeth by type of gear, which during rotation of the auger obewaut internal toothed crown, carrying the grinding - crushing product feed for further pressing. This design works on a "conveyor device pressure (crushing) of the product in the form of the ring gear and the eccentric shifting gears - pressure screw" and it is not possible cutting of the product, which increases energy costs.

The disadvantages of the design according to DE 2550021 should include the complexity of manufacturing, in particular, eccentric feed SNI crown of large diameter with internal toothing, which ultimately increases the cost of a special device, and the obtained product.

The objective of the invention is to develop a device to extract juice from vegetables and fruits, including durum, at home or in the conditions of the farms, which would have simplified and accelerated the process of extracting the juice with more than a full load of the engine universal kitchen machines (food processor), and raw materials for juice would not require a prior thorough grinding, however, the performance of the device and the quality of the juice would be lower than under the current two-stage method of extracting the juice by pressing screw from the pre-crushed material.

The task is solved in that the device for extracting juice works on the type of "feed auger - knife - lattice - pressure screw" that allows sequentially, without interrupting the process, conduct first shredding vegetables and fruits, including durum, and then immediately pressing the crushed raw material pressure screw more fully and efficiently loading the motor of the drive mechanism, while the crushed plant material is pressed by the second auger and not malchiodi knife and a share grating device is made removable and is selected depending on the processed material, and in the lower part protorazuma lattice made grooves (one or more) for flowing the juice released during the grinding of raw materials, from the camera to the screw conveyor in the chamber the pressure of the screw, and feed auger, chopper knife and pressing screw is rotated in one direction and with the same frequency.

In Fig. 1 presents a diagram of a device for extracting juice from vegetables and fruits.

In Fig. 2 shows an embodiment of a grill device with grooves for flowing juice.

The device Fig. 1 includes a feed screw 1 is installed in the housing 2, the receiving rotation from the actuator (not shown).

On the output end of the conveyor 1 has an elongated shaft 3, the shaft has a removable knife 4 and the shaft, speaking, passes through a share grating 5, installed in the housing 2. At the end of the elongated shaft 3 extending from protorazuma grating 5, is mounted tapered roller conveyor auger 6 juicers, located in the annexe 7, having a replaceable filter mesh 8 and the knob pressed. Large base cone of the screw 6 is made in the form of a flat of the knife adjacent to the bars 5 and purifying it from the product in the process. Case 7 attachment extractor is the upper part of the housing (not shown). At the bottom of the grating 5 is made a groove 11 (one or more) for the flow of juice from the housing 2 in additional housing 7 and further replacement filter mesh 8 juicers.

The device operates as follows.

Using components and parts screw grinder universal kitchen machines and consoles extractor collecting device for extracting juice from vegetables and fruits.

Some mechanical improvements require the shaft of the screw conveyor, roller conveyor auger and grille. The output end of the shaft of the screw conveyor install the extension shaft, auger attachment extractor cut with a large basement to get the plane in the form of a knife for cleaning the grates from the juicer, and grilles make the grooves in the bottom for overflow of juice on the filter mesh.

Using modified items, collect the proposed device and, after checking at idle, start getting juice. Small vegetables and fruit is served in the hopper operating device as a whole, and cut into large pieces and receive output from the filter mesh natural juice, and the output from the console juicer compacted waste (spinning). The quality and amount is covigilance), as well as replaceable protivorechashiy grid having apertures of different bore or change the chopping knife grinder (four or two blades).

Experimental validation of the proposed device for extracting juice from vegetables and fruits durum without prior grinding of the raw materials was carried out using household universal kitchen machine "Protein" with a power consumption 360 watts (Household universal kitchen machine "Protein". The user guide. - Ekaterinburg, JSC Uralkhimmash", 1996, 44 C.). Equipping of the ACM "Protein" was the fact that the screw conveyor grinder replaced the output end of the shaft, increasing its length to secure (putting on) the pressure auger juicer with regard knife and grating. When assembling the device on the shaft of the screw conveyor installed knife with four blades and a revised grille with additional grooves in the bottom for overflow of juice, and on the shaft of the screw, the speaker of the grid, set the pressure auger juicer and gathered design according to the presented scheme with a filter mesh.

Testing device spent on obtaining juice from carrots and beets.

Prepared (washed and peeled raw) is then sent a nudge.

Example 1. Carrots, after six months of storage, peeled and chopped in the amount of 630 grams, were processed into juice in the proposed device. The processing time of about 10 minutes. The release of the juice with the pulp of 200 ml or 32% by weight of the feedstock.

Example 2. Beets 1060 grams, after washing and cleaning 920 grams, processed into juice in the proposed device. The processing time of 10 minutes. Juice yield 260 ml or 28.3 per cent.

The tests have shown that the proposed device for extracting juice from vegetables and fruits in a single operation without the prior fine grinding of raw materials is healthy and technically feasible.

Introduction replaceable chopping knife and protorazuma lattice between the screws in conjunction with the revision of the lattice and the installation finalized the pressure of the screw on a slender shaft allows for the processing of vegetable raw materials in a single operation, receiving natural juice without prior shredding vegetables and fruits, similar to juice at the two-stage pressing, but with less effort.

It was found that the novelty is that to obtain the juice by pressing from solid varieties of fruit and vegetables do not require pre-careful Ismaele" and reduces the time of receipt of the juice, improving its quality, as the process occurs continuously in one operation without intermediate exposure to air.

The proposed device for extracting the juice from fruits and vegetables durum without preliminary grinding is not costly to manufacture and can be entered in the kit to a food processor, with the kit should include grille (removable) with grooves for the flow of juice, and the shaft of the screw conveyor can be lengthened or equipped with a bracket extension shaft for Assembly of the device.

The proposed device can be used to extend the range of operations of a food processor at home and in the conditions of the farms, helping to process the harvest of vegetables and fruits.
