The CF coagulator units from GEA carry out the process of milk coagulation, curd cutting, and curd/whey shaking, cooling or heating, to generate maximum yield. The systems offer the flexibility to process curd with enzymes, citric acid or using a combination process with both enzymes and citric acid.
The cylindrical coagulation vat is equipped with a steam-heated jacket for heating or maintaining the curd temperature. A sprinkler distributes the rennet homogeneously throughout the milk. At the end of the cycle, the curd/whey is discharged through a pneumatic valve at the bottom of the tank, and this valve also removes cleaning solutions. The curd churner is driven and controlled by a reliable and robust servo-motor with mechanical reducer and inverter. The production process is managed via a programmable PLC that can set and control all working parameters of the cycle. A memory function allows for up to five presets.
The churner contains a series of sloping blades and balanced stirrers to guarantee homogenous curd mixing and cutting to the required size. The overall design facilitates maximum curd coagulation and maturation:
- A two-dimensional churning motion ensures that the whole mass of curd is turned at each revolution. The balanced stirrers turn the curd axially, while the vat rotation provides radial movement of the curd mass.
- During mixing of the cut curd, radial motion ensures that the grains at the bottom of the churner are brought up to the surface repeatedly, which helps to ensure that all the curds are discharged.
GEA coagulation cylinders are designed to comply with the most stringent hygiene and sanitization requirements. The framework is made of AISI 304 stainless steel, and the interior of the vat features rotary cleaning sprinklers for rinsing at the end of the cycle or for sanitization. Cleaning pipes and rotary sprinklers can be connected to an external CIP plant.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
