Definitions

  • the invention relates to a mixing device for food products according to the features set out in the preamble of claim 1.
  • Such mixing devices are used in particular for mixing meat that has already been minced, such as minced meat.
  • at least one mixer arm always rotates around its bearing axis within a mixing container.
  • DE 17 57 121 A discloses a known mixing device with a mixing container and a single mixer arm mounted centrally therein.
  • the mixer arm is led out of the mixing container at one end and is provided with a chain wheel, which is connected to a drive wheel of a transmission via a drive chain.
  • the transmission is coupled to a motor via a belt drive.
  • it has proven to be disadvantageous that significant drive losses occur due to the belt drive and that both the belt drive and the drive chain wear out comparatively quickly.
  • the invention was based on the object of providing a mixing device that operates more efficiently and with less wear.
  • the mixer has two mixer arms, each with a mixer shaft and a mixer shaft gear wheel attached to it in a rotationally fixed manner.
  • the two mixer shaft gears are preferably designed with the same diameter. Both mixer arms pass through the only common one Mixing container. Both mixer shaft gears and the drive shaft gear are part of the spur gear.
  • the spur gear is a type of gear that is characterized by spur gears on parallel axes. Their advantages are the relatively simple design, as few moving parts are used and the externally toothed spur gears are easier to manufacture.
  • the slip-free coupling of the mixer via the spur gear to the motor results in a particularly low-maintenance, low-vibration, quiet and low-wear operation of the mixing device.
  • the motor has a drive shaft with a drive shaft gear mounted non-rotatably thereon, from which one of the mixer shaft gears is driven directly or indirectly. With a direct torque transmission from the drive shaft gear to the mixer shaft gear, both are directly and permanently in active engagement with one another.
  • the mixer arms are advantageously mounted on opposite end faces of the mixing container. As a result, even at high forces during the mixing process, wobbling movements of the respective mixer arm in the radial direction are largely absorbed.
  • the mixer arm can be a Z-arm mixer, the free ends of which are rotatably mounted on the opposite end faces of the mixing container. It is also possible to shape the mixer arm as a screw mixer, in which a shaft runs between the two end faces of the mixing container, around which a scraper rail attached to it by means of spacers winds in a helically shape.
  • the mixing arm can also be a paddle mixer in which paddles protruding in the radial direction are formed on a shaft running between the end faces of the mixing container.
  • the mixer shaft gears of the at least two mixer arms expediently mesh with one another. This results in an opposite rotational movement of the mixer arms, since the second mixer shaft gear runs on the first mixer shaft gear, which results in an opposite direction of rotation.
  • the opposite rotational movement of the two mixer arms leads to particularly good mixing of the food to be processed.
  • the mixer shafts of the two mixer arms are aligned with one another with a lateral offset and a height offset, the lateral offset typically being a multiple of the height offset.
  • This arrangement leads to a particularly compact shape of the mixing device, since the upward height offset creates free installation space for a motor that can then be at least partially placed underneath. The motor is then arranged on the side of the mixer shaft located further up.
  • a further gear in particular an intermediate gear, can be arranged between the drive shaft gear and the mixer shaft gear, which is directly and permanently in active engagement with the drive shaft gear and the mixer shaft gear.
  • an intermediate shaft gear With the help of such an intermediate shaft gear, a desired transmission ratio of the spur gear can in particular be achieved.
  • the necessary structural distance can be set between the drive shaft gear and the mixer shaft gear using the intermediate gear.
  • the intermediate gear is also part of the spur gear.
  • the drive shaft gear, the intermediate gear and/or the mixer shaft gears are designed with helical teeth.
  • the teeth of the helical gearing do not run parallel to the gear axis, but rather at an angle to it. If a pair of teeth from the wheel and mating wheel come into contact, it does not bear directly across its entire width, as is the case with straight-toothed spur gears without profile correction. Instead, the loaded tooth width slowly increases as the wheels continue to rotate until the pair of teeth supports the entire width, and only slowly decreases again as the wheels are rotated out of the contact zone.
  • helical gear pairs two or more teeth are usually in contact at the same time, so that with helical gears, fewer hard impacts occur during tooth meshing, which results in lower vibration excitation and quieter running.
  • helical gearing when gears run on one another, the opening direction of the teeth alternates as a right-hand or left-hand bevel.
  • the drive shaft gear, the intermediate gear and/or the mixer shaft gears are aligned with one another in a vertical plane.
  • the drive shaft gear and/or the intermediate gear and/or one of the mixer shaft gears at least partially overlap in the vertical direction. This makes it possible to have a sufficiently high design of the mixing container in order to be able to accommodate the largest possible amount of the food to be mixed.
  • the mixer shafts and the drive shaft are aligned parallel to one another. It makes sense that the mixer shafts and the drive shaft are arranged on the same side of the drive shaft gear and the mixer shaft gears.
  • This design further contributes to the fact that the engine is at least partially under the Mixing container can be arranged, whereby the external dimensions of the mixing device are reduced even further. In this installed position, the motor is at least partially covered by the mixing container in the vertical direction.
  • the mixing container can have a bottom wall which is formed with two concave bottom wall sections that are complementary to a movement path of the at least two mixer arms. This results in the advantage that there are no corners within the mixing container in which food to be mixed settles and is not caught there by the circular movement path of the mixer arms.

  • a mixing mechanism 20 is arranged in the mixing container 10 and is driven by a motor 40 via a gear device 30 designed as a spur gear.
  • the mixer 20 has two mixer arms 21a, 21b, which are aligned in their axial extent in the direction of the long sides 12a, 12b of the mixing container 10.

  • the bearing plate 15 is held in a spaced position from the end face 11a in particular by means of a plurality of bearing pins 16 projecting with respect to the end face 11a of the mixing container 10.
  • the bearing plate 15 is preferably aligned parallel to the essentially vertical end face 11a.
  • the spur gear 30 can also be encapsulated to the outside by means of a cover, not shown here, which can also be pushed onto the bearing pins 16.
  • proximal mixer shaft bearings 24a, 24b are attached to the end face 11a of the mixing container 10, the rear, proximal mixer shaft bearing 24a being aligned with the front, proximal mixer shaft bearing 23a and the rear, proximal mixer shaft bearing 24b with the front, proximal mixer shaft bearings 23b.
  • Mixer shaft 22a, 22b runs through both the associated front, proximal mixer shaft bearing 23a, 23b and through the rear, proximal mixer shaft bearing 24a, 24b, whereby each mixer shaft 22a, 22b on two is stored at points spaced apart from one another and radial forces of the mixer 20 are absorbed particularly effectively.

  • the motor 40 with its drive shaft 41 is arranged on the same side A with respect to the spur gear 30 as the mixer shafts 22a, 22b with the associated mixer arms 21a, 21b. This results in a U-shaped flow of force from the motor 40 to the mixer arms 21a, 21b.

During one revolution, both mixer arms 21a, 21b at least partially enter the contour of the respective concave bottom wall section 14a, 14b.
