DE19737007C1 - Turntable stirring arrangement for home brewing vessel - Google Patents

Abstract

A stirrer system for home brewing equipment, used in a vessel closed by a lid, includes a base plate (10), with a turntable (13, 14) above it. This holds the vessel. An electrical drive on the base rotates the turntable. The vessel cover (20) is held stationary, being connected to the base plate. The cover carries a fixed agitator with stirrer blades (17). Preferably the stirrer unit comprises both this fixed section, and a rotating section with stirrer blades (16), which turns with the vessel. The rotating section fits closely against the internal wall of the vessel and is fastened to its the upper edge. The cover and vessel are held without contact, one above the other.

Description

Distribution. In the documents DE 44 40 600 C1, DE 195 24 783 C1 and DE 195 03 244 A1 devices are described which are decisive for this enormous market disadvantage cancel. The only functional group of these devices, mainly because of their placement the stirring unit must meet high demands. Due to the technical and material necessary design, it is the most sensitive and cost-intensive assembly of the devices.

This application was based on the task of creating a problem-free and inexpensive stirring unit create, as the conventional stirring unit attached to a lid several hours exposed to heavy water vapor to meet food hygiene requirements has to lose neither fat nor oil in the smallest quantities and all components 100 degrees Celsius have to be stable. Furthermore, the stirring unit must have a powerful motor and it is with large home brewers when cleaning because of the weight of the lid to decrease.

The object is achieved in that a standard geared motor below a base plate is attached, which is placed on the base plate on a turntable via a friction wheel drive Moves. The container is fixed on the turntable. Next to the turntable are Fasteners connected to the base plate. These bear at their upper ends a lid on which a heating / cooling system is attached centrally. On the tubular body this Systems are attached stirring blades, so that this system also the function of a standing agitator takes over.

To ensure thorough mixing of the brewing material at a low speed of the container achieve, a spiral is preferably attached to the inside of the pot, on which also stirring blades are attached so that this spiral in addition to the pressing task for a flexible filter Function of a rotating stirrer.  

The drawing shows the home brewing device in a sectional view. The gear motor ( 11 ), which rotates the upper part of the turntable ( 13 ) via the friction wheel ( 12 ), is fastened to the base plate ( 10 ). The turntable lower part ( 14 ) with the turntable axis ( 28 ) with the base plate ( 10 ) connected ver. The container is in the container centering ( 27 ) on the top of the turntable ( 13 ). The container ( 23 ) takes the flexible filter ( 24 ), the spiral ( 15 ), the filter basket with bayonet lock ( 25 ) and the hold-down device ( 26 ) and also rotates these parts. The stirring blades ( 16 ) are attached to the spiral ( 15 ).

The lid ( 20 ) is fixed by the fasteners ( 19 ) motionless and be contactless over the rotating container. The heating / cooling system ( 18 ) is attached to the cover ( 20 ) with the heating element ( 22 ). Furthermore, the temperature sensor ( 21 ) is still on the cover ( 20 ). The stirring blades ( 17 ) are attached to the heating / cooling system ( 18 ).

Claims (5)

1. Stirring unit for a container of a home brewing device which can be closed with a lid, consisting of:

• 1. a base plate ( 10 )
• 2. a turntable ( 13 , 14 ) which is rotatably mounted on the base plate ( 10 ) and serves to hold the container,
• 3. an electric drive on the base plate ( 10 ) for the turntable ( 13 , 14 ) and
• 4. a with the base plate ( 10 ) in connection, motionless fixed lid ( 20 ), which has a fixed stirrer with stirring blades ( 17 ).

2. Stirring unit according to claim 1, characterized in that the stirring unit consists of the fixed part with the stirring blades ( 17 ) and a rotating part with stirring blades ( 16 ), the rotating part abutting the inner wall of the container and being attached to the upper edge of the container. 3. stirring unit according to claim 1 or 2, characterized in that cover and Containers are fixed one above the other without contact. 4. Stirring unit according to one of the preceding claims, characterized in that the fixed stirring blades ( 17 ) are attached in the vertical direction on the cover ( 20 ). 5. Stirring unit according to one of the preceding claims, characterized in that two electrical safety devices are provided to prevent danger because of the rotating container, in such a way that, firstly, a housing must be placed over the container before brewing, which when placed on the base plate ( 10 ) releases the drive circuit via a limit switch and secondly the container rotation has stopped when the current consumption of the motor ( 11 ) suddenly increases in a spike.
