Description

The invention relates to the confectionery industry, in particular to devices for mixing chocolate masses.

A device for mixing confectionery masses, containing a container, is known, which mixes the working member, made in the form of a pair of augers, and the drives are upper and lower 1.

 The disadvantage of this device is that when mixing the components of chocolate masses, which include sugar and cocoa particles, partial grinding of sugar particles and cocoa by rotating augers, which engage with each other, occurs. The grinding of sugar particles during mixing contributes to an increase in the viscosity of the mixture, which reduces the quality of mixing.

The closest technical solution to the technical essence and the achieved effect is a device for mixing chocolate masses, containing a heated container, a kneading organ, made in the form of a rocker slide with a horizontal roller, above which there is a turbulization insert consisting of tubular rods parallel to each other connected to each other by a collector, and two lattice partitions, one of which is connected to a vibrator.

However, a well-known device is characterized by a relatively low mixing quality, due to the fact that when mixing components of chocolate masses, in particular cocoa butter, powdered sugar, cocoa liquor and additives, its horizontal roll, moving along the bottom of the container, crushes the hard particles of sugar and cocoa. At the same time, in the process of mixing, the flow of the mixture flowing around the roll above prevents the rotation of the roll, which leads to its sliding along the bottom of the container and thereby more intensive grinding of the solid particles of the mixture. In addition, in the prior art, the flow of the mixture at the bottom of the tank is not sufficiently turbulized, which also reduces the quality of mixing.

The purpose of the invention is to improve the quality of mixing of chocolate masses.

This goal is achieved by the fact that, in a device for mixing chocolate masses containing a heated container, there is a kneading organ made in the form of a swinging curtain with a horizontal roll, above which there is a Turbulization insert consisting of tubular rods connected to each other, and two lattice partitions, one of which is connected to the vibrator, are fixed parallel to one another in the direction of movement of the horizontal roll, on the bottom of the tank, on the surface of which the gear racks are reinforced, and on the roll surface

gear rims are interconnected with gear racks, and additional turbulators are installed, which are a set of brushes reinforced with the possibility of their free ends interacting with tubular rods and having villi of varying length.

At the same time, the toothed racks and toothed rims are made of an elastic material, and the height of the protrusions is 0.15

roll diameter.

FIG. 1 shows schematically an apparatus for mixing chocolate masses, a general sectional view; in fig. 2 - section

A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

A device for mixing chocolate masses contains a container 1 with a jacket 2, a lid 3 and an outlet nozzle 4, rocking the rocker 5 (drive backstage not shown) with the roller 6. On the roller 6 there are gear teeth 7 and turbulators in the form of a set of brushes 8. Each brush individual villi have variable length. The villi are made of spring steel wire with a diameter of 1.5 mm. B bottom

Vessels 1 are parallel to each other protrusions 9, on the surface of which gear racks 10 are fastened. Gear racks 10 and rims 7 are made of an elastic material, for example, rubber, used in the food industry. Gear racks 10 are installed with the possibility of engagement with their teeth 11 with teeth of 12 gear rims 7. There is a gap 13 between the roller 6 and the bottom of the tank 1. The lattice partition 14 is fixedly fixed to the link 5, and in the immediate vicinity of it there is a possibility of vertical movement from the electromagnetic vibrators 15, a lattice partition 16. In the gap between the lattice partitions 14, 16 and the roller 6, a turbulizing insert is placed, arranged in the form of rods 17 parallel to each other with openings along her their length. The rods 17 are interconnected by means of a collector 18, which through pipe 19 is connected to the dispenser 20 of surface-active substances.

The device works as follows. Chocolate components through an opening (not shown) in the lid 3 is poured into the inner space of the tank 1, after which the drive motor (not shown) is turned on and from the swinging link 5, the roll 6 is brought into a reciprocating motion along the projections 9. The gear rims located on the roll 6 7 with their teeth 12 are in engagement with

teeth 11 toothed racks 10, which ensures a constant rotation of the roll 6 when moving the scenes 5. Setting the roll 6 with a gap of 13 relative to the bottom of the tank 1 eliminates the grinding of solid particles of mass between the roller and the bottom of the tank during the mixing process. The absence of the possibility of grinding particles during the blending process allows the chocolate mass to reduce the amount of oversized particles (less than 5 microns in size) in the final mixture, which contributes to an increase in the quality of mixing. In this case, the grinding of particles between teeth 11 and 12 does not occur, because the teeth are made of an elastic material. Simultaneously with the activation of the drive motor, electromagnetic vibrators 15 are turned on, which cause the screen partition 16 to mix upwards and downwards. When the partition 16 is moved relative to the partition 14 therein, the clumps of powdered sugar are destroyed. When the roller 6, rotating, moves along the protrusions 9, flows of the mixed mass are created above it and below it in the gap 13. The stream flowing over the roll 6 from above interacts with the tubular rods 17 of the turbulizing insert. At the same time, the villi located in the brushes 8 in the upper part of the roll 6, when rotated, are retained by the free ends on the rods 17, bend, and with further rotation of the roller 6, the rods 17 slip and the flow of the mixed mass is straightened out of its elasticity. This contributes to an increase in the number of vortices in the stream and thereby its turbulence. Since the individual villi in the brushes 8 have a variable free length, dissection of the flow of displaced mass from one brush 8 occurs many times. Similarly, the flow of the mixed mass, flowing over the roll 6 from below, is turbulized by the villi of the brushes 8, which, when the roll 6 rotates, comes into contact with the bottom of the tank 1. Thus, the brushes 8 turbulent the flow of the mixed mass, pulling the roll 6 from above and below. The presence of the gap 13 contributes to the formation of a hydraulic wedge between the roller 6 and the bottom of the tank 1, which makes it possible to increase the turbulence of the mixed mass in the zone of flow confluence over the roller 6 from above and below. The height of the gap 13 is 0.15 of the outer diameter of the roll b and provides the greatest turbulence of the flow of the mixed mass flowing over the roll below. The increased turbulence of the flows of the mass being blended contributes to a more uniform distribution of the components of the chocolate mass in its entire volume, which improves the quality of mixing. During mixing, from the dispenser 20, through a pipeline 19 and a collector 18 under pressure, surfactants, such as soybean phosphatide concentrate, are supplied to the tubular rods 17. A certain dose of surfactants through the holes made along the entire length of the rods 17 enters the mass directly into the zone of high turbulence of the flows and with the help of the brushes 8 is distributed throughout the entire volume of the mass. This contributes to an increase in the effect of surfactants. During operation of the device, coolant circulates in the jacket 2 in order to maintain the optimum temperature mode of displacement. The finished mixture from the tank 1 is discharged through the nozzle 4. Constructive execution of the device allows reducing the content of overgrown particles (less than 5 microns in size) after mixing by 4.2 times, and increasing the uniform distribution of the solid components of the chocolate mass in a liquid medium by 30%.
