REWORKER UP TO -4°C / -21°C

The Rothenburg RBSX and RBSXS rework systems are used to process frozen butter blocks, cheese or margarine at a temperature of minus 21 degrees Celsius (minus 5.8 degrees Fahrenheit). The blocks are brought to packaging temperature (+8°C to 14°C as a rule) solely by applying kinetic energy.

The systems are designed for an input temperature of minus -21°C or -4°C. The capacity ranges from 0.8t/h to 10t/h. The butter blocks are fed in manually or semi-automatically with a conveyor belt. Our rework system meets all USDA requirements and therefore corresponds to the highest hygiene standard worldwide. It is the only rework system which can make that claim.

We can also refurbish dairy equipment and individual components from your existing equipment.

Functional principle of the Reworker

Large 20-25 kg blocks of butter are fed into the Reworker, which are pre-crushed with the help of the screws and the body geometry. The mass is then further crushed by the front panel mixer and fed to a pump. This pumps the butter through a pin mixer into a butter silo.

1. Reworker

The butter is fed in manually or with a conveyor belt directly into the Reworker. With the help of specially manufactured screw conveyors, the frozen butter block is pre-crushed and at the same time conveyed to the next stage.

2. Front panel mixer

Two counter-rotating mixer shafts serve to crush the butter further and prepare it for feeding into the connected butter pump

3. Butter pump

Generously dimensioned butter pumps equipped with a rectangular flange ensure gentle transport of the butter.

4. Pin mixer

The heart of the system. High shear forces are used here to achieve ideal fine water distribution and spreadability. The desired output temperature can be freely controlled here via frequency converters.

5. Butter silo

The butter silo, with its large screw conveyors, serves as an ideal buffer tank for the following packing machines.
