Preparing the Milk Portions
Carryover:
If an animal does not entirely consume the available feed quantity until midnight, there will
be a quantity left that is carried over to the following day. Consequently, at midnight the va-
lue is not zero but it corresponds to the carryover. The quantity exceeding the carryover is
not transferred to the next day but it is cancelled.
Maximum quantity:
To avoid excessive milk or concentrate intake due to too high minimum save--up quantity,
the animals can only claim limited quantities. Once the maximum quantity is attained, the
entitlement is blocked for two hours. The accumulated quantities are not cancelled.
9.1 Preparing the Milk Portions
The warm water is taken from the boiler of the heat exchanger. The milk pump delivers the
milk through the stainless steel coil of the heat exchanger into the mixer jar.
The circulation pump -- if available -- keeps the warm boiler water moving at high speed
thus effecting rapid heat transfer to the liquid inside the stainless steel coil. 15 minutes after
the last portion has been distributed, the circulation pump switches off automatically. Every
15 minutes the pump switches on for 1 minute or in case an animal claims its milk portion.
When the liquid jet hits the supply electrode (short electrode) in the mixer jar, a pre--set milk
powder portion falls from the powder hopper into the mixer jar where it is mixed with the
liquid. The mixer is connected by a suction hose via a box valve to the feeding station. The
milk flows through the suction hose to the teat in the feeding station.
If the milk ratio for all animals falls below the set threshold value, the automatic feeder will
commute automatically to „single heating circuit“ at midnight calculation. Milk and water
are taken from the stainless steel coil. In this way, the milk does not stay too long inside the
coil. S ee chapter 11 ff, page 97 ff, „Milk Functions“, „Selecting the Milk Ratio for Change--
