Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Preferred embodiments of the present invention are explained in more detail below with reference to the drawings. Similar or similarly acting components are designated in the figures with the same reference signs.

[0019] FIG. 1 shows a spatial representation of an open concept kneading machine.

[0020] FIG. 2 shows a spatial representation of the kneading machine of FIG. 1 with an additional quickly detachable cover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The kneading machine 1 shown in FIGS. 1 and 2 is designed for processing a food dough, in particular a baking dough. The kneading machine 1 has a kneading machine frame 2, the head portion 3 of which can be swiveled about a swivel axis 100 between a lower operating position and an upper cleaning position relative to a lower portion 4. The head portion 3 carries the kneading tool 5, shown here are two oppositely rotating spiral kneaders, and the drive required for a rotation of the kneading tool 5, as well as a cover 7, which is provided for covering the kneading bowl 8, which is open at the top. The kneading bowl 8 and an electric motor 9 are arranged in the lower portion 4 of the kneading machine 1. The electric motor 9 rotates the kneading bowl 8 about an axis of rotation, which is not shown, relative to the kneading machine frame 2. Furthermore, a swivel drive 10 is placed in the head portion 3, which is designed as a linear drive and has an electric motor. The swivel drive 10 is supported on the lower portion 4 in a swivel joint 11. By moving the linear drive, the distance from the head portion 3 to the lower portion 4 is increased or decreased, resulting in a swiveling of the head portion 3 relative to the stationary lower portion 4 about the swiveling axis 100.

[0022] The kneading machine 1 has a housing 12 formed of stainless steel sheets. The housing 12 covers only the drive of the kneading tool. The kneading machine frame 2 is largely exposed and is not surrounded by the housing 12.

[0023] An additional cover 200, shown in FIG. 2, which serves as an outer covering, is attached to the kneading machine frame 2. The cover 200 is attached to the kneading machine frame 2 in a quickly detachable manner. The cover 200 is made of a food-safe, water-impermeable material, in particular plastic or fiber-reinforced plastic. However, stainless steel or a fabric tarpaulin may also be used. In the preferred embodiment shown, the cover 200 has a plurality of panels 201, each of which covers a gap 21 formed by the struts 20 of the kneading machine frame 2 towards the outside. Preferably, the cover 200 replaces the conventionally used housing, i.e., it seals off the kneading machine 1 from the outside except for the kneading bowl 8 and the kneading tools 5. The cover 200 has no inwardly projecting surfaces or recesses, and the number of contiguous surfaces of the cover 200 is reduced to a minimum, so that the cover 200 is easy to clean and no specially trained personnel are required for cleaning. Cleaning is preferably done with brushes or with jet water <10 bar. The quick release connections 22 allow the cover 200 to be easily and quickly removed and attached without the need for additional tools. The quick release connections may be zipper connections, clip connections, hook-and-loop tape connections, or a combination thereof.

[0024] Other quick-release form-fit fasteners may also be used, such as snap-fit fasteners or other quick-release fasteners such as bayonet fasteners or the like.

[0025] The cover may also be connected to the kneading machine frame and/or housing by detachable connections such as cords, buttons, hooks and eyes.

[0026] It is advantageously provided that the cover is made of a transparent material. This allows the operator to check the condition of the kneading machine without removing the cover, and in particular to check whether the kneading machine has become dirty under the cover. If cleaning, repair, or maintenance is required, the cover can be quickly and easily detached and removed from the kneading machine. The material of the cover is preferably chosen so light that the cover can be removed by one person alone.

[0027] The cover can be made in several parts, whereby the parts are also preferably connected to one another by quick-release connections.

[0028] It may also be provided that the cover has a resealable opening that allows one to reach or walk through the cover and thus makes the kneading machine frame accessible without having to remove the entire cover.

[0029] The cover allows cleaning to be carried out as usual without extra effort despite the open concept of the kneading machine. The cleaning personnel do not have to be specially trained and can maintain the usual cleaning procedure. The cover can also be manufactured inexpensively and is preferably easy to attach and remove by one person without tools.

[0030] While preferred embodiments of the present invention have been described above, it is to be understood that variations and modifications will be apparent to those skilled in the art without departing from the scope and spirit of the present invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
