The invention relates to a device for washing the grain of butter for machines for continuous making of butter, consisting of one at the outlet end one around a horizontal one Axis rotating drum for separating and separating the buttermilk from the butter grain with this coaxially arranged, rotating frustoconical washing drum for the grain of butter, the larger base area of which is the exit end of the drum for separating and separating the buttermilk is facing from the butter grain, in which of the frustoconical washing drum enclosed interior washing water nozzles are arranged, the jets of which are approximately vertical are directed, and the frustoconical washing drum has a perforated wall part for discharge of the washing water from the washing drum.

In a known device of this type, the drum is for separating the buttermilk from the butter grain Truncated cone-shaped and has a perforated ring for draining the buttermilk as well as at the end of the largest base area a perforated part for the introduction of sprayed from nozzles Washing liquid on, and the equiaxed to the frustoconical drum for separating the Truncated cone-shaped washing drum for the buttercorn arranged with buttermilk from the buttercorn encloses the washing liquid nozzles. At the end of the washing drum facing the separating drum a conical sieve belt is provided, to which an uninterrupted part of the washing drum connects. During the operation, buttermilk and butter grain are turned into the smaller diameter end introduced into the rotating separation drum. On the way to the widening end of the separation drum a large part of the buttermilk is already removed from the separating drum. At the end of Separating drum, the butter grains are used to free any buttermilk residues adhering to them Wash water sprayed. The butter grains then fall from the end of the separation drum into the washing drum, are deflected in their direction of movement and move on the inner surface of the conical Wash drum down to the sieve belt through which part of the wash water flows out radially while the butter grains over the sieve belt and in the direction of movement of the butter grains on them subsequent uninterrupted part of the washing drum slidingly together with the rest of the Wash water get into the presser.

In the known device so move the butter grains in the same direction through the device for washing the butter grain for

Device such as the wash water, d. that is, they are expanded by the wash water together with the wash water The end of the separation drum is flushed out and in the washing drum together with the washing water rinsed to the presser. Because the butter grain follows the flow of the washing water and therefore only for a short time is washed, the degree of cleaning of the washed grain of butter is not fully satisfactory. Another shortcoming of the known device is that a certain proportion of the Butter grains pressed radially through the openings of the sieve belt and discharged with the washing water will. The device does not work without loss.

The invention is based on the object of a device for washing the butter grain for machines for the continuous production of butter to create a highly effective, lossless Washing of the butter grain can be achieved.

This object is achieved in that the perforated wall part for discharging the Wash water from the washing drum in the plane of the larger of the two base surfaces of the frustoconical Washing drum lies.

This design of the washing drum ensures that the butter grain during its way towards the end of the washing drum

the washing water flowing downwards in the direction of the perforated wall part, whereby a results in very effective countercurrent washing, the degree of purity of which is similar to that of a repeated Ablution reaches. So the washing water comes out at one end of the washing drum, while the In contrast to this, grain of butter practically without loss at the other end of the drum Further processing leaves.

In an embodiment of the invention, on the inner surface of the frustoconical washing drum known per se, arranged in the direction of the axis of rotation of the washing drum extending strips be, which serve as a driver for the butter grain and its discharge from the washing drum support.

An exemplary embodiment of the invention is shown schematically in the drawing. It shows

F i g. 1 is a side view of the entire device and

Fi g. 2 essentially a longitudinal section through the washing drum in an enlarged compared to FIG Scale.

A butter-making cylinder 2 with a rotating butter-making element 3 is mounted on a rock, wherein an outlet pipe 5 is arranged at the outlet end 4 of the buttering cylinder, the lower The end 6 opens into a rotating drum 7. Near the exit end of the drum? are located passages 8 through the buttermilk separated from the butter grain to a stationary buttermilk outflow chamber 9 goes off.

At the exit end of the drum 7 is a frustoconical Washing drum 10 is arranged, the larger base area of which faces the outlet end of the drum 7 is facing. In the plane of the larger of the two base surfaces, the washing drum 10 is perforated Wall part II provided through the fed through a pipe 14 and approximately vertically downwards directed jets 15 sprayed washing water reaches erne drain chamber 12. On the inner surface of the washing drum 10 are strips extending in the direction of the axis of rotation of the washing drum 13 arranged for taking along the grain of butter.

Located under the exit end of the washing drum 10 see an inlet port 16 to a kneader 17, from the outlet end 18 of which the kneaded butter emerges,

The following is the mode of action of the invention Washing device described.

The buttering cylinder? is of the not shown At the end of the cream supplied from the Buttering organ 3 is beaten and as a mixture of butter grain and buttermilk in the common occurs with the washing drum 10 rotating drum 7 about a horizontal axis.

The buttermilk is separated in the drum 7 from the butter grain by having the buttermilk diverted through the passages 8 and out of the drainage chamber 9 is deducted.

Thereafter, the butter kernel contaminated with buttermilk residues migrates into the washing drum 10, where it is during its movement through the washing drum is sprayed with water and washed. The wash water flows through the perforated wall part 11 and reaches the drainage chamber 12, from which it is discharged becomes .. The butter grain moves in countercurrent to the gradient of the washing water. There the water jets perpendicular, d. H. directed essentially parallel to the perforated wall part 11 there is no risk that the grain of butter will be knocked through the perforation.

Claims (2)

Patent claims: 1.
