Tetra Therm®Lacta PMO
Dairy pasteurization unit

Application
Tetra Therm Lacta PMO is a dairy pasteurization unit designed
for continuous processing and pasteurization of Grade “A” milk,
cheese milk, yoghurt milk, cream, ice-cream mix and other low
acid liquid dairy products, according to the standards of the U.S.
Pasteurized Milk Ordinance (PMO) and the 3A Sanitary Standards.

Working principle
Tetra Therm Lacta PMO is automated to safeguard production.
Production is strictly controlled by production recipes with
processing parameters and a separate public health PLC.
Main process sequences can be divided into the following main
steps
• Production
- Pre-sterilization
- Filling
- Processing / circulation
- Emptying
• Cleaning-In-Place
• Inspection

Before production can commence it is necessary to sterilize the
unit by circulating hot water for 20 minutes. After pre-sterilization,
the unit is cooled down and stabilized to production temperatures.
If there is a time gap between pre-sterilization and production, the
unit could be set in hibernation mode. This is an energy
conservation mode in which the energy consumption is decreased
up to 85% compared to the hot water circulation mode - by
reducing the power, steam and water consumption.
When downstream equipment is ready, production can start.
Production starts by filling the unit with product from the balance
tank. The product displaces the water/product mix to drain, white
water tank or reject tank.
The balance tank includes level control and a CIP device, which
safeguards the gentle treatment of the product and ensures a high
degree of cleanability.
