Double Jug

The dilemma of whole milk storage

Whole milk feeding is becoming more and more important in calf rearing. However, there are a few technical obstacles to be overcome for feeding at the calf feeder. There has to be a constant supply of milk in the storage tank, for example, because the calves come to feed all day long. But if the calves drink more than usual, the tank is empty too quickly and the animals do not get any milk for a certain time.

On the other hand, there is often some milk still left in the tank when it is to be refi lled and cleaned. This is often simply drained. Since this is expensive, however, the fresh milk is often just added to the old milk in the tank and feeding continues without the storage tank being cleaned properly.

In addition, conventional milk tanks start to freeze over when the level in the tank is very low, which is a problem. It damages the milk and puts a strain on the technology. For this reason, we have developed the ultimate solution for you for the storage of whole milk for calf feeders like the CalfExpert. Find out on the next page how the DoubleJug solves all the problems described above.

Double Jug - Unique in Whole Milk Storage

The DoubleJug is a milk tank that has been designed especially for automatic calf feeders. Since there are two tanks integrated in one unit, milk is always available and optimum hygiene is guaranteed.

24 hours whole milk feeding

The CalfExpert calf feeder draws its milk from one of the tanks. Should this tank become empty, the DoubleJug switches automatically to the second tank and the CalfExpert can continue to feed without interruption. This means no waiting times and no interruptions in feeding, thus making ideal use of the high performance of the CalfExpert.

Controlling the DoubleJug via the CalfExpert

The DoubleJug is controlled via the CalfExpert and programmed at the feeder display. This allows the tank status to be viewed directly at the feeder and in CalfGuide at any time. There is an information unit attached directly at the DoubleJug which indicates the most important information such as temperature, fi lling level etc. directly in the barn.

Automatic cleaning

The DoubleJug is controlled via the CalfExpert and programmed at the feeder display. This allows the tank status to be viewed directly at the feeder and in CalfGuide at any time. There is an information unit attached directly at the DoubleJug which indicates the most important information such as temperature, fi lling level etc. directly in the barn.

Refilling whenever convenient

Once a tank has been cleaned, DoubleJug is ready for fi lling. Usually both tanks are fi lled to take advantage of the maximum capacity of the DoubleJug. The advantage of the two-chamber system is that the DoubleJug can be fi lled at any time without having to wait for the exact moment the milk tank is empty. There are neither residual quantity nor times during which the CalfExpert stops feeding due to lack of milk.

Cool stuff

The DoubleJug is equipped with a cooling unit for both tanks. Even small amounts of milk are cooled effi ciently without freezing.

Space even in the smallest room

Thanks to its square design, the tank does not take up much space in the calf barn. This means it can be positioned close to the calf feeder.
