RAINBOW control:

The milk cooling tank is equipped with a RAINBOW tank control. The new Rainbow cleaning system ensures efficient cleaning with a patented spray system. The cleaning times have been optimized and improved in line with the use of automatic milking systems (AMS). An integrated microprocessor stores data such as milk and cleaning temperature, Power interruptions u. a. Events for a period of at least 3 months.
It is an intuitive touch screen. The control is suitable for milking parlor or milking robot. Control of cooling, cleaning and stirring is easier. Very easily visible parameters, such as display of the code and its description. Windows application for the PC to quickly query the most important functions.

Main tasks of the milk tank control:

1. Control of the cooling process
2. Control of the cleaning process
3. Control of stirring
4. Monitoring and registration of temperatures


Delayed start of the first milking. It is possible to display 2 setpoints for the temperature. You have the possibility of hypothermia. The cooling capacity can be adapted to the cooled milk volume.

1. Cooling units with hermetic compressor 2. Cooling capacity according to the ISO 3. Scroll refrigeration units with low power consumption 4. shut-off valve of the refrigerant at standstill of the condenser 5. Cooling regulation by thermostatic expansion valve. Optionally available:
- Compact version up to 2x6 hp
- With separate condensers and tank-mounted compressor   from 2x6.5 hp to 2x10 hp
- With separate cooling units
- Without refrigeration unit
- Coolant R 404A
style="padding:5px; font-size:12px;" valign="top" Cleaning:
The new Rainbow cleaning system ensures efficient cleaning with a patented spray system (baffle plate). The cleaning times have been optimized to adapt to the use of automatic milking systems (AMS).

The rainbow control is equipped with two dosing pumps for the automatic dosing of the cleaning agents. The amounts to be dosed are adjustable, the switching between alkaline and acidic cleaning agent is adjustable.

Agitator and homogenization:
A slowly running stirrer motor with approx. 25 rpm. Cyclic automatic stirring is programmable. Homogenization of the milk fat takes place within 2 minutes according to standard ISO 5708.

Connection to the milking robot possible:
With robotic milking, the cows can be milked all day (24 hours), which gives a constant milk flow to the milk cooling tank.
The rainbow control is equipped with an interface for direct connection to a milking robot. When using an intermediate tank, the milk is sent there as long as the milk cooling tank is emptied and cleaned. If no intermediate tank is used, the robot is switched off during emptying and cleaning of the milk cooling tank. For this, the rainbow controller sends commands to the robot.
After successful cleaning, the Rainbow controller will close the automated milk tap and cooling will start automatically. If the cleaning was not successful, a corresponding alarm message is generated.

The advantages at a glance

The ellipsoidal tank allows cooling even with small quantities of milk and thus ensures optimum cooling performance. Designed by SERAP, the refrigeration unit adapts to standard refrigeration and climate events. In the design of the cooling system in particular a simple maintenance was in the foreground, both in the cooling unit and in the components of the Rainbow cleaning system.
