Description

 The invention relates to household appliances and the food industry and can be used to obtain juices from stone fruits.

 A device for producing juice from fruits with seeds is known, comprising a body, a lid with a hopper for supplying fruit, a conical perforated rotor, the bottom of which is a grater disk, and a device for isolating seeds.

 The disadvantage of this device is the low degree of squeezing the juice, due to the short duration of the ground product on the grater and perforated surfaces. Under these conditions, the bones do not have time to completely clear the pulp, and the juice is completely removed from the pulp.

 Known juicer (ed. St. USSR N 944532, class A 47 J 19/00, 1989), which contains, along with the traditional perforated conical rotor, a grater mounted inside it on the same shaft in the form of a cylindrical glass with a perforated wall, a grater surface which is located on the inside of the cylindrical wall. The loading shaft is sloped reinforced to provide product feed to the grater surface. The abrasion of the product in this juicer is made by a cylindrical surface, the area of which is greater than the area of the rotor base, on which a regular grater disk could be installed, and the juice is pressed in two steps on the walls of a cylindrical perforated grater glass and on the walls of a conical rotor.

 However, in such a device, peeled (crushed) fruits will tend to rise up the wall of the glass, which complicates and slows down the process of obtaining juice.

 A known design of a centrifuge of a juicer containing a grating disc and a filter made of two parts (see ed. St. USSR N 1584898, class A 47 J 19/00, 1990). The lower part of the filter adjacent to the grinding disk is cylindrical, there is no perforation on it and ribs are provided that are inclined to the side opposite to the direction of rotation of the centrifuge. The upper part of the filter adjacent to the lower part is made in the form of a truncated inverse cone and provided with perforation. During centrifuge operation, the ribs hold the ground mass on the cylindrical part for better squeezing of the juice. The squeezed cake is then, in subsequent portions of the crushed mass, moved along the upper surface of the ribs to the conical part and discarded from the centrifuge.

 This design cannot be used for stone fruit processing, in addition, the abrasion area is small.

 A device for removing seeds from fruits, selected as a prototype, comprising a housing, a drive, on a vertical shaft of which there is a perforated rotor and a grating disk connected to the housing, is a feeder made in the form of a conical sleeve entering the rotor; teeth are made on a part of the inner surface of the conical sleeve. To remove the seeds, the feeder has partitions radially located in the conical sleeve with valves and slots, and the drive shaft is hollow and has an inclined plate located inside it. On the side surface of the shaft at the level of the inclined plate, a window is made connected with the branch pipe for the removal of ossicles. To prevent the accumulation of ossicles in the shaft cavity, a shaft connected to the lid is installed in it with an eccentricity (see ed. St. USSR N 1382471, class A 23 N 4/00, 1988).

 The disadvantages of the prototype can be attributed to the small abrasion area of almost only the grater disk, since the teeth on the inner surface of the fixed conical sleeve located above the grater disc only partially participate in the process of grinding and grinding the product, they peel only the fruits that bounce off the grater by centrifugal forces disk and striking against the inner, mainly lower part of the sleeve. In addition, the design is complex. The drive shaft is weakened due to the presence of a pit cavity in it. Setting up such a juicer is time-consuming (installing valves on partitions) and requires considerable experience. Fruits and seeds, even in one batch of the product, can be very different, so small seeds, which are not completely cleaned from the pulp, can jump through valves that are set to medium size.

 The purpose of the invention is the creation of a simple device for processing stone fruits, providing quick and high-quality separation of the pulp from the seeds, regardless of the size of the fruits and seeds.

 To this end, in a device for processing stone fruits containing a housing, a drive, a perforated rotor, a reverse cone shaped grating element with internal teeth, a feeder with a conical part extending into the rotor, and a stone removing window according to the invention, the rotor is made in the form of a grated an element in the form of an inverse cone with internal teeth, a wire spiral is fixed on the lower part of the inner surface of the grater element, the direction of the turns of which is opposite to the direction of rotation of the rotor, on the outer surface The surface of the conical part of the feeder, which enters the rotor to the level of the wire spiral, is fixed with a tape spiral, the width of the turns of which corresponds to the gap between the cones of the rotor and the feeder, and the direction of the turns coincides with the direction of rotation of the rotor, the upper end of the tape spiral approaches the lower part of the window to remove seeds made in the inlet of the feeder.

 The combination of the functions of the rotor and the grater element by supplying the perforated rotor with teeth on the inner surface allows to increase the efficiency of bone cleaning by increasing the abrasion area (the entire grater side surface works) and simplify the design. The presence of a wire spiral, the direction of the turns of which is opposite to the direction of rotation of the rotor of the grater element, allows you to slow down the movement of the cleaned stone fruits up the rotor wall, that is, increase the contact time of the fruit with the grater surface and, therefore, improve the quality of cleaning. The presence in the gap between the grater surface of the rotor and the conical surface of the feeder extending inside the rotor, a ribbon spiral, the direction of the turns of which coincides with the direction of rotation of the rotor, allows to ensure a gradual rise along with the ongoing contact of the stone fruits, which are still not completely peeled from the pulp, with the grater surface seeds to the window for unloading seeds.

 Thus, in the inventive device, productivity is significantly improved and the quality of stone fruit cleaning is improved, sequential movement of the fruits to be cleaned to the unloading window is automated while significantly simplifying the design by combining various functions with individual elements (rotor grater, feeder feed cone, seed removal mechanism), and also provided the possibility of high-quality cleaning of fruits, regardless of the size of both the fruit and the seeds.

 The inventive device has distinctive features from the prototype and analogues and does not follow explicitly from the studied structures, therefore, meets the criteria of "novelty" and "inventive step". Such a device can be widely used both in everyday life and in enterprises of the food industry and public catering, therefore, it meets the criterion of "industrial applicability".

 The drawing shows a General view of the claimed device.

 A device for processing stone fruits contains a housing 1, inside of which a drive 2 is placed, a perforated rotor 3 mounted on a vertical shaft of the drive 2, and a feeder.

 The rotor is a glass having the shape of an inverse cone. The inner side surface of the rotor 3 is provided with grinding teeth. The teeth may be the bent portion of the burr obtained by punching the hole. The burr point of the tooth is directed towards the rotation of the rotor 3. In the lower inner part of the rotor 3, a wire spiral 4 is fixed (2-3 turns). The direction of the turns of the spiral 4 is opposite to the direction of rotation of the rotor 3.

 The feeder comprises an inlet cone 5 connected to the housing and a feed cone 6 placed concentrically in the rotor cavity 3. The feed cone 5 has an eccentricity relative to the feed cone 6, the axis of the latter coincides with the axis of the rotor 3. Both parts of the feeder are rigidly interconnected, for example by welding. A tape spiral 7 is fixed on the outer surface of the feed (return) cone 6, the direction of the turns of which coincides with the direction of rotation of the rotor 3. The width of the turn of this spiral 7 is selected taking into account the gap between the return cones of the rotor 3 and the feed part of the feeder 6. Spiral 7 should not prevent rotation rotor 3. The upper end of the tape spiral 7 approaches the lower edge of the window 8 for removal of pits, made in the periphery of the inlet part of the receiving cone 5 of the feeder. The window 8 is closed from above by a cap 9, forming an output channel directed towards the periphery of the receiving cone 5.

 The operation of the device is as follows.

 Fruits from the hopper fall onto the feed cone 5 of the feeder, roll along it, pass through the feed cone 6 and fall to the bottom of the rotating rotor 3. Under the action of centrifugal forces, the fruits are discarded to the walls of the rotor 3 and tend to rise along them, but the wire spiral 4 located in the lower part of the rotor 3, prevents this. The perforation teeth of the rotor 3 peel the fruits. The wire spiral 4 has a small turn width (wire thickness), therefore, the movement of the fruit up the rotor wall does not stop, but only slows down, thereby providing better cleaning of the seeds from the fruit pulp. Almost peeled bones that have risen above the level of the wire spiral 4, fall on the surface of the tape spiral 7. Since the direction of the turn of this spiral 7 coincides with the direction of rotation of the rotor 3, the bones, continuing to interact with the grater surface of the rotor 3, rise along the tape spiral 7 to the window 8 in the receiving cone 5. The cap 9 restricts the movement of the seeds up and to the side, concentrating the flow of seeds in the direction of the outlet hole, from where they fall into the capacity of the collection of stones (not shown). The pulp from the cavity of the rotor 3 under the action of centrifugal forces passes through the perforation and is fed for further processing or use.

 The inventive device provides an increase in productivity and an improvement in the quality of pulp separation, which is associated with an increase in the surface area producing peeling and a longer contact of the fetus with the grater surface. In addition, this device excludes the possibility of premature removal of unrefined fruits. The design allows high-quality processing of fruits of different sizes, with different sizes of seeds, without additional settings.
