RU179212U1 - Kneading machine - Google Patents

Abstract

The utility model relates to equipment for the baking industry and is intended for the preparation of dough. The kneading machine contains a bowl for kneading dough with a drive and a kneading body made in the form of a rotating shaft mounted in the center of the bowl, on which rotary kneading working bodies are installed along the generatrix of the screw with decreasing pitch in the direction of the ingredient loading zone. The utility model allows to improve the quality of the batch by eliminating the imperfections of the test and increase the productivity of the equipment. In the claimed utility model, the effect is achieved by continuous mixing and transporting the ingredients along the generatrix of the screw round along the rotating shaft and at the same time by a complex movement relative to the axis of the rotating kneading working bodies and the rotating shaft.

Description

The utility model relates to equipment for the baking industry and is intended for the preparation of dough.

The closest analogue is a kneading machine (patent No. 2379893, IPC А21С 1/02, 2010) containing a bowl with a drive and a kneading organ, on which replaceable kneading blades of the same length but different in diameter depending on the density of the dough kneading are installed from top to bottom .

The disadvantage of this machine is the low quality of mixing and the increase in the duration of kneading due to the small area of contact of the kneading blades with the dough.

The technical task is to create a machine that improves the quality of mixing the dough and increase productivity. This problem is achieved by the fact that the ingredients are continuously mixed and transported along the generatrix of the auger winding along the rotating shaft and at the same time along a complex path relative to the axis of the rotating kneading working bodies and the rotating shaft. Reducing the installation step of kneading working bodies in the direction of the loading zone of the ingredients increases the speed of moving the dough from bottom to top, high-quality mixing of the dough, reducing the duration of kneading due to interaction with rotating kneading working bodies.

The proposed utility model differs from the prototype in that on the rotating shaft along the forming coil of the screw with decreasing installation step in the direction of the ingredient loading zone, rotating kneading working bodies are installed.

The figure 1 presents a diagram of a dough mixing machine; in figure 2, view A in figure 1; in figure 3, a section through the BB in figure 1; figure 4 is a section along the explosive in figure 3.

The kneading machine contains: an electric motor 1, the shaft 2 of which is connected by a coupling 3 to the input shaft 4 of the worm gear 5, the output shaft 6 transmits rotation to the shaft of the kneading body 7, on which the rotating kneading working bodies 8. The kneading body 7 is placed in the bowl 9. On the rotating shaft of the kneading body 7 along the generatrix of the auger turn accommodates rotary kneading working bodies 8 with a decrease in the pitch of their installation in the direction of the ingredient loading zone (figure 2). On the shaft 7 (figure 3), the fingers 10 are rigidly fixed, on which are mounted kneading working bodies 8 of a cylindrical shape, on which three kneading blades are placed 11. The locking ring 12 prevents the rotation of the kneading working bodies 8 from the fingers 10. To prevent the dough from falling into a knocker 13 is installed inside the kneading working body 8. The kneading blades 11 are concave in the direction of rotation of the kneading shaft 7 and are placed at an angle of 120 ° relative to each other (figure 4).

Kneading machine works as follows.

In the bowl 9, the necessary components for kneading are loaded, the electric motor 1 is turned on, which transmits torque through the shaft 2 and the coupling 3 to the input shaft 4 and through the output shaft 6 of the worm gear 5 clockwise to the shaft of the kneading organ 7.

Mixing of the dough takes place in the machine due to the rotation of the kneading body 7, on which rotating kneading working bodies 8 are installed along the forming part of the screw with a decrease in the step of their installation in the direction of the ingredients loading zone.

Kneading working bodies 8 rotate clockwise about its axis, due to the pressure created by the test on the blades 11 during rotation of the kneading body 7. The maximum pressure of the test is experienced by the concave surface of the blade in the upper vertical position, the pressure on the other blades due to their shape and location , at this time, the minimum, which sets in motion the kneading working bodies 8.

The installation of kneading working bodies 8 on the shaft of the kneading body 7 along the forming coil of the screw with a decrease in the pitch in the direction of the loading zone of the ingredients increases the speed of moving the dough from bottom to top, high-quality mixing of the dough, reducing the duration of the kneading due to interaction with rotating kneading working bodies 8.
