At the heart of the dairy production process

  • Low energy consumption, thanks to a rapid response hibernation system and compact unit design
  • Numerous features support food safety, before and during production
  • An automation system controls the operation of this unit and connected submodules, enabling efficient production

Features

Divert system

Divert system

Ensures correct pasteurization

The temperature of the product is verified both before and after the holding cell. Product can only continue out of the pasteurizer if it has been heated to the right temperature and held for the right length of time in the holding cell. If this is not the case, a signal is automatically sent to the divert valve, and the product is diverted back to the balance tank for recirculation.

Pressure differential

Ensures food safety

Booster pumps create a differential pressure between the pasteurized and unpasteurized side of the unit. To further enhance safety, this differential can be monitored by pressure transmitters. If these transmitters 'notice' that the differential has not been maintained, the product is automatically diverted back to the balance tank for recirculation.

Automatic hibernation

Minimises energy consumption

During water circulation, the flow in the pasteurizer can be decreased, the cooling can be stopped and most connected sub-modules can be switched off. This so-called 'hibernation' minimizes the amount of steam, energy and water consumed while waiting for product to enter the system. The ramp up and ramp down time is only about 2 minutes, which makes it worthwhile using hibernation even during short periods of water circulation.

Target-based production

Saves time and reduces risk of human error

This feature enables production of a certain amount of milk and cream – either set as a certain number of litres or programmed to continue until the FMT tank is full (or the source tank is empty). If connected to a separator and standardization unit, it is also possible to define a specific fat content. Operations such as CIP, water circulation and switching to a new recipe can be set up in advance, to be performed automatically in sequence, without the need for human intervention.

Integrated leakage test

Enhances food safety

Before or after production runs, the integrated leakage test lets you pressurize the system to verify that there is no drop in pressure – implying a leak – in the plate heat exchanger or downstream. This is important as a leak could lead to contamination from the pasteurized to the unpasteurized side during production.

Low-loss balance tank

Minimizes product loss

A smart balance tank configuration makes it possible to remove the maximum amount of water before product enters the tank, thus reducing the mix of water and product. This method lowers the number of litres in the mix phase by over 50%, leading to a significant reduction in product losses.

Continuous pressure control

Continuous pressure control

Increases food safety

During production there is normally a pressure differential between the pasteurized and unpasteurized side, to minimise the risk of leakages and keep the product safe from contamination. However, that during discharging (from the separator) this pressure differential usually disappears. In the Tetra Pak® Pasteurizer D, a pressure control system overcomes this problem. It compensates for the pressure dip, thus the avoiding the risk of leakages and contamination.
