Description

 The invention relates to the food industry, namely to the catering system, and can be used in the processing of fruits and vegetables to produce juices.

 Known juice extractors of the "SV-I" type, comprising a housing with a juice collector, a lid and a loading funnel, a rotor sieve and a grater disk associated with the output shaft of the drive, as well as a pusher (E.V. Lear, I.V. Petko devices.Kiev, Technika, 1990, p.64, Fig. 1.37a).

 During the operation of the juicer, the product is loaded into the loading funnel and fed with a pusher to the grinding disk, which grinds the product pressed to it. Under the influence of centrifugal forces, juice flows through the perforated surface of the rotor sieve into the juice collector.

 When operating such a juicer, the presence of an operator performing a sequential loading of the product is necessary, it is pressed against the waste disc.

 Juice squeezers are known in which special pressing elements are used to clamp the product to the grinding disc. For example, an electric juicer (ed. St. USSR N 1412725, class A 47 J 19/00, 1988) contains a housing for collecting juice and ejecting cake, a lid with a loading container, as well as a cone-shaped grater and filter, which are fixed to motor shaft. The electro juicer is equipped with a pusher, which ensures that the product is pressed against the grinding device. During operation, fruits or vegetables are loaded into the container and pushed with a pusher to prevent the product from ejecting from the container. Fruits are rubbed moving on a rotating grinding device.

 This design is equipped with a pusher, which ensures that the product is pressed against the grinding device. The squeezing of the fruit with the pusher requires the constant presence of a person. During operation, the fruits and grated mass under the action of centrifugal forces will recline to the walls of the loading container and stick to them, which will reduce the performance of the electric juicer.

 This design of the electric juicer does not exclude the slipping of fruits along the walls of the loading container and its rotation together with the grater, which worsens the rubbing. Further feeding of the fruit with the pusher from the loading container can lead to overloading of the electric juicer.

 The objective of the invention is to create a simple and technological design of the juicer, which provides an increase in area and increase the efficiency of the clamp mechanism, which will ensure high-quality abrasion of the product and increase productivity.

 To solve this problem, in a juicer containing a housing with a loading device and a juice collector, a drive with a rotor sieve and a grater disk with a knife on its vertical shaft and a device for compressing the product to a screw disk with downward spiral-shaped elements, the direction of the turns of which is opposite to the direction of rotation of the grating disk, according to the invention, the clamping device is a body part mounted with an eccentricity in the rotor sieve, made in the form of a cylindrical body, Shackle walls which form a toroidal recess is formed, the recesses formed on the surface of the spiral flutes whose height gradually decreases toward the periphery of the pressing device.

 The product is pressed to the grinding disk and knife by the toroidal surface of the body part with spiral corrugations, the direction of the turns of which is opposite to the direction of the grinding disk, and the height gradually decreases, which allows for high-quality and quick abrasion of products of various sizes and separation of parts from them on the entire surface of the grinding drive.

 The proposed design has features that are absent both in the prototype and in analogues, and therefore meets the criterion of "novelty." The essence of the proposed technical solution does not follow explicitly from the studied array of information and therefore it can be assumed that it meets the criterion of "inventive step". The juicer will find wide application in everyday life, in the food industry, i.e. it meets the criterion of "industrial applicability".

 Figure 1 presents a General view of a juicer, section; figure 2 view a in figure 1; figure 3 section BB in figure 1.

 The juicer contains a housing 1, inside of which the drive 2 is placed. On the vertical shaft of the drive 2 there is a bowl-shaped rotor sieve 3, a grater disk 4 and a knife 5, which is a boss with three pointed cutting blades. A juice collector 6 and an additional housing 7 with a device for clamping the product to the grinding disc 4 are fixed on the housing 1. A hopper 8 with a loading nozzle 9 is installed above the additional housing 7.

 The clamping device is made in the form of a body part 10, made in the form of a cylindrical body, on the sides of which a depression of a toroidal shape is formed. Part 10 is installed inside the rotor sieve 3 above the grating disk 4 with an eccentricity relative to the axis of the drive 2 and is fixedly mounted on the additional housing 7. A guide rim 11 is installed on the upper plane of the part 10 of the concentric torus surface. Here is also a device for removing the pulp.

 The torus-shaped body part 10 is provided with spiral-shaped corrugations 12, progressively decreasing to the periphery of the part 10, the direction of the turns of the corrugations is opposite to the direction of rotation of the grinding disk 4.

 Juicer operates as follows. Fruits or other products (both hard and soft) are loaded into the hopper 8, where they are oriented one by one or in batches, depending on size, are fed through the loading nozzle 9, the guiding rim 11 and the inner cavity of the body part 10 to the blades of a rotating knife 5. The falling of the product on the blades of the knife 5, and not on the central non-working part of the boss of the knife is ensured by the presence of an eccentricity between the rim 11 with the toroidal body part 10 and the grater disk 4 with the knife 5. The falling fruits are torn (crushed) by the blades of the knife 5 and the garbage are pressed onto the grater disc 4. Under the action of centrifugal forces, rather large parts of the product after the knife are clamped between the corrugated toroidal surface of the body part 10 and the grater disc 4. The smaller the pieces, the farther from the axis of the torus they move. The corrugations 12 of the body part 10 contribute to the advancement of the abrasive product to the periphery. A progressive reduction in corrugation 12 prevents product slippage. A completely crushed product under the action of centrifugal forces is fed to the walls of the rotor sieve 3. Juice passes through the holes of the rotor sieve 3, and the pulp accumulates on its walls. To remove it, a device is periodically activated that scrapes the pulp from the walls of the rotor sieve 3 and removes it from the juicer. The juice enters the juice collector 6 and from there through a special nozzle into the container.

 Thus, the use in the design of the juicer to hold the product to the grinding disk in the form of a toroidal shaped body part with eccentricity with corrugations of a given orientation and configuration allows for fast and high-quality crushing and abrasion of any products, both solid and viscous (fruits, vegetables). The clamp is carried out over the entire surface of the grater disc, the design of the clamping element is quite simple and technological, the fastening is simple and reliable.
