Description

 The invention relates to the confectionery industry, more specifically to a device for molding sugar cookies.

 Known methods for molding powdery and confectionery products, such as cookies, were carried out by filling the rotor cells with tin, later protocryl-M (plastic). Filling with tin and protocryl-M carries a lot of labor, i.e. pouring time 2-3 weeks. Protocryl-M material is expensive and very toxic when used, and most importantly, the replacement of failed forming elements is associated with high costs. Potent for invention 2144769 dated January 27, 2000 was received.

 Known injection installations in mechanical engineering [1, 2]. Known injection plant [3], consisting of a bed, an extruder with a worm, housing. Mixing pins are mounted on the inner surface of the housing with the possibility of controlling their axial movement. The pins are located on the bushings. The bushings are movably connected to the housing by means of a thread. The disadvantage of this installation is the complexity in the design and manufacture, the inconvenience of replacing the pins, as they are in the bushings, i.e. in the inner surface of the housing.

The present invention relates to the processing of polymeric materials for pouring rotors (sugar cookies) in the confectionery industry. The features that distinguish the proposed installation from the closest [3], characterize: increase the productivity of the installation, ease of maintenance, to achieve this technical result in the installation for filling with polystyrene cells of the rotor for molding powdery-confectionery products, consisting of a bed, a hopper and an extruder containing a cylinder with a furnace head and a worm, the worm is made with a cut, the depth of which is 3.5-4 mm, and the tilt angle is at least 15 ^o , while the radial clearance between the cylinder and the worm is 0.05-0.07 mm (to obtain a given degree of plasticization of homogenization, "Greek uniform" see [6], p. 325, 1022).

 The authors developed a technical process for the production of polystyrene segments for a three-dimensional pattern of cookies using an installation for filling rotor cells with polystyrene to form powdery and confectionery products. Thus, this installation can be used repeatedly and with a different assortment of patterns (cookies).

 In FIG. 1 shows the installation for filling polystyrene cells of the rotor for molding powdery-confectionery products, General view. It contains an extruder 1, an extruder plate 2, an electromechanical nature 3, an injection machine bed 4, a brake device 5, a rotor bed 6, a mold 7, a lagometer 8, a thermocouple clamp 9, a furnace head 10, a rotor 11, a hopper 12.

 In FIG. 2 shows the installation, the second projection.

Figure 3 shows the cylinder 1, the worm 2, made with a thread, the depth of which is 3.5-4 mm, and the angle of inclination is not less than 15 ^o , while the radial clearance between the cylinder and the worm is 0.05-0.07 mm .

 Depending on the degree of plasticization and homogenization of the mixture, the sizes are taken empirically. For example, in the prototype [3] ... "in advance empirically determine the position of the pins in the bushings relative to the channel of the coils, and then during the mixing process, they finally make adjustments to create the desired profile of the passage sections."

 Installation for filling polystyrene cells of the rotor for the formation of powdery and confectionery products works as follows. Polystyrene is loaded into the extruder through the loading hopper 12 directly from the commodity packaging (bags), creating a certain temperature of polystyrene, it moves along the worm and through the furnace head 10, under high pressure, polystyrene is injected through the die into the cells of the rotor 11 through an automated extrusion process.

 This installation for filling with polystyrene cells of the rotor for molding floury confectionery products works at the enterprises of the confectionery industry of Russia and has positive reviews.
