Process plant for cheese premix production

Cheese making usually involves a certain number of separate processes and interruptions, making it somewhat tedious. Our aim was to supply our customers with a machine that produced top quality cheese premix without unnecessary steps and waiting times.

Advantages compared to the previous process:

The individually configured system operates on the basis of a Conti-TDS. Liquid and powder are fed automatically into the process. As a result, the customer has a hygienic system that is ideally suited for use in the food industry.

  • The process plant combines a Conti-TDS 3 wetting and dispersing machine as well as a process vessel with 2800 litres of useful volume, in addition to a side-mounted jet mixer, a plate heat exchanger and powder hopper, piping and fittings. 
  • The process plant features a compact design on a common base frame. The base frame stands on load cells. Metering of raw materials is performed via the load cells. 
  • Concentrated skimmed milk is metered out via load cells in the process vessel. Palm oil is added via one of the Conti-TDS intake nozzles. This leads to the creation of a stable emulsion within this process step.
  • The second Conti-TDS intake nozzle is used to induct the powdered components, e.g. milk powder and a powder premix. These components are wetted spontaneously to form an agglomerate-free product.
  • The product is heated and pasteurised via a heat exchanger integrated in the bypass circulation line. 
  • The finished product is cooled via a plate heat exchanger and transported directly into the buffer tank of the bottling plant via a displacement pump adapted to the discharge line.
  • One of the big advantages of the process plant is its compact design: Many individual process steps were combined and bundled into the smallest possible space. 
  • Process steps that were previously performed manually can now be performed automatically by the plant control. Personnel expenses have been reduced significantly compared to the previous procedure.
  • The process time was also reduced by more than 50 %.
  • This process automation ensures a high degree of reproducibility. This also results in a predictable, consistent product quality.

“Previously, our customer implemented the different process steps of production using different process plants - so it wasn’t so easy to convince him that he only really needed one single process plant for the entire production process!”
