Description

Continuously operating kneading machines are known, made in the form of a horizontal cylindrical chamber with two consecutive zones designed for pre-mixing and working out the dough. The first chamber is equipped with a working body, which is a yush; it is a shaft with a conveyor, pressurized, screws and radial blades located between them, and the second zone has an internal corrugated surface and there is a working body in it, which is a corrugated cylinder, reinforced on the horizontal axis, driven in the direction of the vrash movement. The proposed dough kneading machine, as compared to the known ones, allows for a better study of the dough. This advantage is achieved by the fact that the working body of the study zone is formed by several corrugated cylinders, which are fixed on the axes with the possibility of free rotation relative to them, and the axes themselves are connected to the frame, which is driven into rotational motion by an individual drive, and the zones of the chamber are separated by a partition with holes for the passage of the test. The chamber in the pre-mixing zone of the test is made paired and there are two working bodies of the same design in it. FIG. 1 shows a general view of the proposed kneading machine, in section; in fig. 2 shows a section along LL of FIG. one; in fig. 3 is a section along BB, FIG. one; in fig. 4 shows a kinematic scheme of a kneading machine. The kneading machine is made in the form of a horizontal chamber with a receiving funnel / and outlet pipe 2, divided by a transverse partition 3, having windows 4, into two interconnected zones 5 to 6, respectively, used for preliminary mixing and subsequent processing of the dough. The camera in zone 5 is made paired and there are two combined working bodies 7 installed in the counter-rotation. The gallop from the working bodies 7 is a shaft 8, at one end (under the funnel 1) of which there is a twin-screw auger 9 for moving the components of the dough and pre-mixing it, and on the other - a single-turn pressing auger 10 with a step less than the pitch of the screw 5 perpendicular to the axis of the working body 7. The chamber in the dough processing zone 6 is formed by the body 12, into which the corrugated glass 13 and the working body 14 are inserted. To prevent the internal corrugated dough from sticking, the surface of the glass 13 is covered with a polymer film, Example fluoroplastic-4. The operating member 14 consists of two cylinders 16 freely floating on the axes 15 and having a lateral corrugated surface, which are made of a polymeric material. The axes 15 are fixed on the frame 17 connected to the end of the drive shaft 18. The working bodies 7 of the mixing zone 5 are driven from the electric motor 19 via a worm gear 20 and a pair of gear wheels 21 sitting on the shafts 8. The working part 14 is the test working areas It has an independent drive consisting of an electric motor 22, a V-belt drive 23 and a worm gearbox 24. The kneading machine is equipped with a flour-type metering unit 25 for flour and a piston metering unit 26 for liquid ingredients supplied through pipe 27. The metering units are operated from the shaft 8 via chain drives 28 and 29. The kneading maschina operates as follows. Flour and liquid ingredients from the respective dosing units, as well as water from an automatic water measuring tank (not shown), enter the mixing zone 5 of the chamber. In order to evenly feed the raw material, the flour from the dosing unit 25 is fed to the screws 5 through the receiving funnel 1, and the liquid ingredients with water flow through the collecting pipe 27. The pre-mixed components are moved by the screws 9 to the middle part of the transfer zone and worked through the blades 11. Next, the resulting dough falls on screws 10 and pressing them out through the windows 4 of the partition 5 into the working zone 6. In zone 6, the dough is subjected to intense mechanical action by repeatedly rolling it in a thin layer between the inner the flank surface of the cup 13 and the grooved surfaces of the cylinders 16 of the working member. The finished dough from the study zone is delivered through the nozzle 2. Subject of the invention 1. A continuously operating kneading machine, made in the form of a horizontal chamber with two consecutive zones for pre-moving and testing the test, in the first of which there is a working body, which is a shaft with a transporting and pressing screws and radial blades located between them, and the second zone has an internal corrugated surface; there is a working body in it, made in the form of a cylinder with p An angled surface fixed on a horizontal axis, rotated, characterized in that, for the purpose of better processing the dough, the working body located in the study zone is formed by several corrugated cylinders which are fixed on the axes with the possibility of free rotation relative to them, and the axes themselves are connected to a frame driven by an individual drive, the chamber zones being separated by a partition with holes for passing the dough. 2. The machine according to claim 1, wherein the amer in the pre-mixing zone and the test is made paired and there are two working bodies of the same structure in it.
