To keep milk fresh, it is necessary that the milk that is warm from the cow is cooled down as quickly as possible will. For this purpose, the milk-filled jugs to be cooled are usually placed in trough-like jugs Container used, whereupon cooling water is sent through this.

However, the cooling achieved in this way is uneven; the one adjacent to the can wall Milk will be cooled quickly, but the milk will stay in the middle of the jugs for longer Time warm, which gives the acid-producing bacteria the opportunity to become active.

In order to remedy this disadvantage, devices have already been developed through which the Milk is stirred while it is being cooled.

Devices have already become known in which the filled into a large vat Milk by cooling coils moving up and down in this od. The like. Cooled and stirred and the called movement of the cooling coils by their alternating loading and unloading by means of this supplied cooling water is effected and controlled. Such devices are, however, for rural use Businesses in which the milk produced in each case is for their own consumption or for dispatch to dairies is filled in a smaller or larger number of milk cans is unsuitable.

There are also devices known in which the cooling and stirring of the milk in the Milk cans is carried out by yourself.

Such a device consists, for example, of a trough into which the milk-filled cans and which is continuously filled with cooling water up to a certain height. For stirring the milk, this device can be used as stirring elements in the milk cans, Plates attached to guide rods are provided, which by means of pulleys guided by cables to a box which is arranged on the front side of the cooling device and can be moved vertically are attached, to which the draining cooling water is supplied and the resulting effect Loading and automatic unloading the said plates are raised and lowered.

However, apart from their high cooling water consumption, these cooling devices are conditional by using the above-mentioned cables, which in turn are connected to the corresponding milk cans Racks also require the arrangement of guide pulleys or pulleys, for farms under construction much too complicated and too much too due to the wear and tear of the cables running over the guide pulleys Device for cooling and stirring milk in jugs

sensitive. Also the operation of such cooling devices by hanging the stirring plates into the individual milk cans and their Lifting out of the cans cumbersome, especially since this often has the disadvantage that the

! 5 pull ropes jump out of their roller guides and only then have to be used again in this. Must for larger systems for reasons of space the milk cans not only one behind the other, but also in pairs next to each other in the cooling troughs or cooling troughs are set up, the above-mentioned cable mechanism controlling the agitator plates, including the required for this and to be actuated by the draining cooling water, the raising and lowering of the plates causing the water box, even more complicated and the Device even more complicated to operate. This device is also used for the Raising and lowering the stirring plate, the time required for filling and relieving the water tank Much too big to allow quick and perfect cooling and Durohmixing of the milk with it could be achieved. In any case, those lifted out of the milk cans after cooling are also disturbing and now the lifting of the milk cans from the cooling trough over this hanging stirring plate or the insertion of new filled milk cans to be processed into the cooling trough.

According to another known device for cooling and stirring in cans Milk, in which the filled jugs are also placed in a cooling trough filled with cooling water the stirring plates to be hung in the milk cans are attached to one above the cooling trough Crankshaft attached, which is set in rotation by a motor.

However, this device also has various disadvantages.

A first disadvantage of this device is that, if, as in larger farms, in the cooling trough a larger number of filled milk cans to be cooled and stirred should be set up, a relatively long time

Claims (1)

3 4 Cooling trough must be used, because, due to 'follows' here appropriately by the free end of the the use of crankshafts for the suspension pendulum shaft encompassing, open at the bottom, U-shaped the stirring plate, the filled milk cans are just a piece of pipe that is attached to the penin by a pivot pin Row is hinged next to each other in the cooling troughs delwelle.

For the installation of the- 5 this piece of pipe while taking all the stirring Long cooling troughs, however, can be folded up in the farmer's plate, resulting in the last Often operated no space at all. tere at the same time from the area of the milk cans In addition, the aforementioned installation requires the lifted and pivoted so that the cooling milk cans in a row next to one another the use trough is easily accessible from all sides and the appropriately long crankshafts with one of the io milk cans lifted out of it unhindered Milk cans to be processed corresponding add-on or new filled cans are used in these of crooks for the suspension of the can. Stirring plate. When using such a long crank the invention will be explained in more detail with reference to the drawing waves, as they are described, for example, on farms. In this illustrated:

Such a work is the pipe section 7 with the suspended from it wise, however, is very tedious. Mixing plates 9 folded up, as shown in The invention is intended to provide the above-mentioned fig. 3 is indicated. This way the parts get eliminated. 35 stirring plate from the area of the cooling trough W, see above The invention relates to a device for cooling that this is accessible from all sides and the gelation and stirring of milk in cans, filled milk cans 11 can be inserted into it, the one guided in two bearings, by a motor. The pipe section 7 is then provided with the agitator-controlled shaft, on which the agitator plates are folded back over the learners 9, the agitator plates are inserted into the cooling trough extending area, agitator plates open to 4 ° milk cans and the pendulum shaft 3 is hung through. The invention consists in the fact that the electric motor 4 is set in a pendulum motion, used for raising and lowering the stirring plate, whereby the milk in the cans is cooled by the cooling water fed to the shaft from a tub W guided on one side in two bearings, and the same and through a motor and crank mechanism is carried out in good time. controlled pendulum shaft, on which the agitator plates are moved over the 45 After cooling is complete The area extending from the cooling trough is lifted out of the milk cans one behind the other and a number of cross bars attached and the latter by pivoting the pipe section 7 from the Stirring plates are suspended. Trough area brought so that the milk cans The use of such, with cross bars without hindrance by the stirring plate and their equipped pendulum shaft has to be taken from the essential 5 ° suspension of the cooling trough part that now at each end of the cross bars ever can. a stirring plate can be attached so that instead of the stirring plate, place them in the area of the Depending on the number of cross bars, to move the same cooling trough or out of its area, to pivot with number of milk jugs next to one another and at the same time by means of the pipe section 7, they can also be placed in pairs in the cooling trough without such pivoting . In this way, the pendulum shaft for stirring a certain number of milk cans then needs to be attached to the crossbar by hand by means of its support rods 10 and only those inserted or after cooling has ended, or half the length of one for stirring the same number of milk cans used to clean it from the cross bars 8 to be 60 crankshaft. In any case, the cooling trough will have, since when using it, as he already imagines the stirring devices unhindered, easily from all sides, the milk cans in the cooling trough are only accessible,
can be placed side by side in rows. This saves space, and there are vibrations of the drive shaft 65 claims: the stirring plate avoided.
