 A device for producing juice with pulp (ed. St. N 1551339, class A 47 J 19/00, A 23 N 1/00, 1990), consisting of a housing with a receiving funnel, a perforated conical section with a sieve, a juice collector with pulp and unloading device with cutting elements, inside the housing and the perforated conical section is a screw, consisting of a cylindrical feed section and a cylindrical pressing section with cutting elements.

 The disadvantages of the known device are low productivity, an increased amount of waste containing juice, a complex structure, unreliability and inefficiency during operation.

 The disadvantages of the analogues are due to the fact that the aforementioned devices for producing juice with pulp are intended for processing soft in texture, juicy plant materials with a low content of biologically ballast tissues. Basically, these devices are used in the processing of fruit and berry raw materials (tomatoes, apples, grapes, strawberries, etc. with a high content of biologically ballast tissues, as well as solid varieties of raw materials (carrots, potatoes, beets, squash, etc.) , the operation of the device is inefficient and unreliable, inefficient, there is a high humidity of the waste.

 The closest in technical essence to the claimed device is a device for producing juice with pulp (ed. St. N 1634242, prototype). The device consists of a housing with a receiving funnel, a perforated conical section with a sieve, a grinding mechanism, a screw, mounted on a shaft, which is fixed in the bearing assembly, is located inside the housing and the perforated conical section.

 The disadvantages of the prototype are: low productivity; the operation of the device is inefficient and unreliable; complex design of plate knives.

 These disadvantages are due to the constructive solution of the prototype. The plant mass that has not passed through a sieve installed in the perforated conical section of the body enters the chamber of the grinding unit, where it is exposed to serrated and plate knives, which is ineffective. The plant mass is subjected to grinding from motionless teeth. The design of lamellar knives is complex and unreliable in operation, at a high rotation frequency (1400-2000 rpm) the raw material mass, which agglomerates in the chamber of the grinding unit, leads to the destruction of lamellar knives. The easily flowing puree mass, crushed in the grinding unit, is displaced by the undigested particles coming from the perforated attachment again, which underestimates the performance of the device (as opposed to the forced one in the inventive device).

 The purpose of the invention is to increase productivity, increase the reliability of the device and simplify the design.

 This goal is achieved by the fact that in the proposed device for producing juice with pulp, blade knives located on the rotor of the cylindrical chamber of the grinding unit are serrated and mounted at an angle to the axis of the drive shaft, and the cylindrical chamber of the grinding unit is closed by a spring-loaded conical insert.

Salient features of the invention are:
1. The cutting edge of the blade knives is made serrated.

 2. Toothed knives are installed in the rotor at an angle to the axis of the drive shaft.

 3. The cylindrical chamber of the grinding unit is closed by a spring-loaded conical insert.

 The implementation of the cutting edge of the plate toothed knives leads to the fact that particles of plant tissue that have not passed through a sieve of the perforated conical section of the body are subjected to cutting and crushing effects from both fixed toothed knives and from rotating ones. The cutting-crushing effect of gear knives leads to fine grinding of the plant mass, which is an easily flowing puree mass. Rotating toothed knives better and faster carry out the process of fine grinding than contribute to increased productivity.

 The installation of gear knives in the rotor at an angle to the axis of the drive shaft contributes to the forced displacement of finely ground puree-like, easily-flowing mass, which leads to an increase in productivity. This is due to the fact that the plant mass does not linger (is not pressed) in the grinding unit, but with back pressure it is forced back into the perforated attachment. The interaction of forced displacement (with serrated knives) and newly incoming plant materials contributes to the additional cleaning of the sieve perforation with finely ground puree-like, easily-flowing mass, as well as the dilution of hard, hard particles of plant mass, which also contributes to an increase in productivity.

 The cylindrical chamber of the grinding unit is closed by a spring-loaded conical insert, which increases the reliability of the device. This is due to the fact that when operating the device for producing juice with pulp on raw materials that have undergone minimal heat treatment (in order to maximize the preservation of biologically active substances of vitamins, amino acids, etc. and improve the aesthetic parameters of finished products used for baby and diet food (color, taste, smell), particles of hard tissue that did not pass through a sieve and foreign objects (stone, wood, bolt, nails) that may be in the plant mass did not press the grinding chamber and did not bring If the pressure in the grinding unit exceeds the pressure created by the screw, the spring-loaded conical liner leaves its place and opens the outlet for solid particles or foreign bodies.

 When comparing the proposed solution not only with the prototype, but also with other technical solutions, no solution was found that has similar characteristics.

 In FIG. 1 shows a General view of a device for producing juice with pulp in a section; figure 2 node grinding; figure 3 is a section aa of the grinding unit; figure 4 gear knife; 5, the rotor of the grinding unit.

 A device for producing juice with pulp consists of a housing 1, a perforated conical drum 2 with a sieve 3, a grinding unit 4 (FIGS. 2 and 3) and a screw 5, worn on the drive shaft 6, fixed in the bearing assembly 7. The juice with the pulp is collected in a casing 8 worn on a perforated conical drum. The rotation of the shaft on which the auger is mounted provides an electric motor through a V-belt transmission.

 A device for producing juice with pulp works as follows.

 The raw material enters the housing 1, where it is picked up by the screw 5 and transferred to the perforated conical drum 2, where it is rubbed through the holes of the sieve 3. Moving by the screw along the perforated conical drum, the plant mass located in the inter-turn channel of the screw experiences increasing pressure, particles with a more rigid structure are rubbed. Particles of plant mass having a high hardness of tissues cannot be destroyed and rubbed through the openings of the sieve. Under the action of the screw, these particles fall into the grinding unit 4. In the grinding unit, solid particles are finely chopped, falling under the intense influence of stationary gear knives 9 and rotating gear knives 10, mounted at an angle to the axis of the drive shaft 6 on the rotor 11. As a result, the solid particles having a rigid structure are destroyed and are an easily flowing puree mass, which is freely displaced by newly arriving solid particles and rotating gear knives installed at an angle to the axis of the drive shaft. The displaced, easily flowing puree mass is rubbed through the openings of the sieve. All juice and pulp that passed through the openings of the sieve are collected in the casing 8 and sent for further processing. When creating a pressure in the grinding device 4, exceeding the pressure created by the screw, the spring-loaded conical insert 12 leaves its place and opens the inlet for solid particles or foreign bodies.

 The technical advantages of the proposed device for obtaining juice with pulp are to increase productivity, increase reliability and simplify the design.

 The socially useful advantages of the proposed device are safety in the highest percentage of biologically active substances (vitamins, amino acids, etc.), improvement of aesthetic and dietary nutrition (color, taste, smell).

 The experimental installation of a device for producing juice with pulp was tested at the Tiraspol experimental factory of canned baby food in a carrot processing line in the 1991-1992 season. The test data showed that the device for producing juice with pulp can reduce the temperature load on the plant tissue by heat treatment before wiping, which allows to increase the productivity of the production line, and also that this device is more reliable in operation and simpler in design.
