The invention relates to a vertically standing device for scalding pigs after Parting off, with a closed chamber, which is suspended from movable carriages on an overhead conveyor Pigs go through to this dei 5 exposure to sprayed by atomizer exposure to hot water circulating in a closed circuit using a circulating pump, Devices for heating the circulating water and one on the one hand via the pump the atomizers and, on the other hand, with an opening in the concave bottom of the chamber Contains connected water tank.

The known devices of this type have the disadvantage that this is done in a closed circuit Circulating scalding water quickly becomes dirty and its microbe content reaches a critical value, so that the scalding water no longer meets the strict hygiene regulations in a short time. Man has therefore already proposed that the polluted scalding water, if necessary, by adding fresh water to be partially renewed. Renewing the scalding water, however, requires an interruption of the scalding treatment of the pigs, which leads to considerable loss of time. In order to increase the number of company »5 To reduce breaks, a coarse filter and a coarse filter are used in the scalding water circuit Fine filter built in series, which is designed as a backwashable double filter. But also in this case, the device must be switched off to clean the filter.

The present invention avoids these disadvantages and has the object of a vertically standing device to create for scalding pigs after tapping of the type mentioned at the beginning, which allows the scalding water to be completely to renew as soon as its pollution and especially its microbial content is critical Has reached value without the operation of the device having to be interrupted.

In a device of the type mentioned above, this object is achieved according to the invention by that two independent water tanks are available, which are optionally switched into the circuit and so can be connected to the atomizers.

In this design, a water tank with the necessary accessories such as heating device, circulation pump, fresh water inlet, drain, etc. is in operation, and as soon as the pollution in this water circuit has reached the critical value, then on the other water perpendicular device for scalding

can be switched over and the scalding water completely renewed in the former.

It is particularly advantageous to have a device for heating the water in each water tank to be provided, as this allows the heating power of the individual devices to be kept low.

Furthermore, in the device according to the invention, the drain line is in two each to a water tank leading branches divided, each of which contains a valve and a coarse filter behind this. That anytime possible replacement of the scalding water makes it possible to use less filtering to be satisfied by means of a coarse filter, which largely reduces the risk of clogging this filter is reduced.

About the contamination of the scalding water and thus the frequency of its replacement and cleaning to reduce the filter even further, the actual scalding chamber is preceded by a washing chamber, in which the pigs are hosed down with cold water, which is already a large part of the impurities adhering to them is removed.

The invention is explained below by way of example with reference to the drawing.
