装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for centrifugally sterilizing milk, comprising:
Milk is fed into the feed section of a centrifugal drum, in which the centrifuged concentrate containing bacteria accumulates, and a portion of this concentrate is passed through a discharge passage provided with a nozzle to the centrifugal drum. Derived from centrifugal drum,
The present invention also relates to a type in which the remaining concentrate is periodically discharged through a discharge port provided on the outer wall of the drum. Furthermore, the invention relates to a device for carrying out the above method.

Processes of this type are known and are advantageously used for sterilizing milk for cheese production and drinking milk. A suitable centrifuge for carrying out this process is, for example, the West German patent application no.

使用することができるにすぎなくなる。 Approximately 3% of the milk volume supplied via the feed section of the centrifugal drum is withdrawn as bacteria-containing concentrate via a discharge channel equipped with nozzles. Another 0.3 of supply
% is periodically removed as bacteria-containing concentrate via the outlet of this centrifugal drum. The bacterial concentrate thus obtained contains, inter alia, bacterial strains that have an adverse effect on cheese quality. The two partial streams are then combined again and subjected to a heat treatment in a special sterilizer, in which case all bacterial strains are killed. The sterilized concentrate can then be added back to the kettle milk. However, when sterilizing drinking milk, it is not allowed to reintroduce the sterilized bacterial concentrate into the drinking milk, so that the amount of bacterial concentrate produced is lost when producing the drinking milk. In fact, there are even moves to ban the addition of sterilized bacterial concentrates to dairy products in principle. This bacterial concentrate can then only be used as low-paying feed.
本発明の課題は、生じる細菌濃縮物量を著しく
減少させることのできる、牛乳を遠心除菌する方
法を提供することである。
The object of the invention is to provide a method for the centrifugal sterilization of milk, which makes it possible to significantly reduce the amount of bacterial concentrate produced.
上記の課題は、ノズルを介して導出される濃縮
物を濃縮物室の中央範囲から引出し、遠心ドラム

The above object is solved by drawing off the concentrate discharged via the nozzle from the central region of the concentrate chamber and returning it to the feed of the centrifugal drum.
意外にも、本発明による方法を用いれば流出す

に、ノズルを介して導出された全濃縮物量を供給
部に戻すことが可能であることが判明した。 Surprisingly, it has been found that, using the method according to the invention, it is possible to return the entire concentrate quantity drawn off via the nozzle to the feed without adversely affecting the quality of the sterilized milk flowing out. found.
このことは、ノズルを介して導出される部分量

およびノズルを経由する進路を取るので、流入す
る牛乳中で返送により菌数の重大な増加が生じる
ことはない。これにより、除菌された牛乳中での
菌数の予想しうる増加は起こらない。 This is based on the fact that the portion delivered via the nozzle is drawn from the central region of the concentrate chamber, where only a small amount of bacteria is present.
That is, the bacteria contained in the concentrate accumulates particularly on the peripheral wall of the drum near the outlet, while the remaining components of this concentrate, fats and proteins, enter via the outlet passage and nozzle. Returning in milk does not result in a significant increase in bacterial counts. This does not result in a predictable increase in the number of bacteria in the sterilized milk.

なわれしまうであろう。 The area in which the portions delivered via the nozzle are drawn off is selected such that on one side skimmed milk with as low a bacterial content as possible is drawn off, and on the other side still fat particles are not removed together with the skimmed milk. Should. Otherwise, this skimmed milk would be spoiled.
公知の遠心ドラムの場合、生じる菌含有濃縮物

た部分量を遠心ドラムの供給部に返送すること、
遠心分離器の流出部中の細菌濃度を除々に増大さ
せ、ひいては除菌された牛乳の品質に不利な影響
を及ぼす恐れがある。 In the case of known centrifugal drums, both partial volumes of the resulting bacteria-containing concentrate are drawn off from the peripheral wall of the concentrate chamber. Both portions therefore have high bacterial concentrations. Therefore, returning the drawn-off partial quantity via a discharge channel equipped with a nozzle to the supply of the centrifugal drum;
This can lead to a gradual increase in the bacterial concentration in the centrifuge outlet and thus have an adverse effect on the quality of the sterilized milk.

なしでは、分離効果は著しく劣悪となる。 It has been found possible to have the passage leading to the nozzle start from the central area of the concentrate chamber, thereby drawing off almost sterile skim milk, without any disadvantage to the separation effect of the centrifugal drum. The withdrawal of this partial quantity is therefore only necessary in order to exert a suction effect on the bacteria in the concentrate chamber so that these bacteria migrate to the peripheral wall of this concentrate chamber. Without this suction effect, the separation effect would be significantly poorer.

がつて、これらの変動量を捕集するためのこれま
で必要とされた相応に大きな積重ね容器は不要と
することができる。 In one advantageous embodiment of the invention, the concentrate discharged via the nozzle is divided into two partial streams, of which the first partial stream is returned to the feed of the centrifugal drum and the second partial stream is fed to the outlet. The amount of this second partial stream is adjusted in dependence on the amount of concentrate flowing out of the outlet so that a constant output concentrate stream is produced after the merger.
This is advantageous for the subsequent sterilization step. This is because a constant power must be supplied to this sterilization process. The correspondingly large stacks of containers previously required for collecting these fluctuations can therefore be dispensed with.
遠心ドラムの搬出口から噴出される濃縮物量が
全濃縮物量のわずか約10％であるにすぎないの
で、一定の容量流を発生させるためには戻り導管
から小さな部分流を分岐させるだけで十分であ
る。 Since the amount of concentrate emerging from the outlet of the centrifugal drum is only about 10% of the total concentrate amount, it is sufficient to branch off a small partial stream from the return conduit in order to generate a constant volumetric flow. be.

Due to the Coriolis forces acting in the outlet channel 6, a sufficient spacing "A" is necessary regardless of the cross section of this outlet channel 6. This interval “A” is
Good results have been obtained if a throughput of approximately 15/h per mm of spacing "A" is chosen for the individual outlet channels 6. For example, when 20,000/h of milk containing bacteria is supplied to a centrifugal drum and 5% of it is drawn out as a concentrate containing bacteria through the outlet passage 6 formed by eight ribs 19, this outlet passage A processing capacity of 20000/h x 0.05:8 = 125/h is obtained for each 6.
