Description

These are used for closed processing of products of different viscosity (milk, milk drinks, cream, ice cream mixes, milk desserts, creams, juices with pulp, etc.).

outlet product temperature, °С - for cold filling - for hot filling	+4...+6 unspecified (set on the control panel)
holding time, sec **	20...25 (for drinking milk) 300 (milk for fermented milk products)
Primary heat-transfer agent Secondary heat-transfer agent	Steam Hot water (for recuperation sections)
Steam consumption, kg / hour (for condensate)	150	400	550
Cooling agent (basic design)	ice water (+ 1 - + 3 °C), glycol solutions, brines

* The capacity of pasteurization and cooling stations can be set arbitrarily by the Customer in the range of up to 10,000 l/h.

** Time of holding at pasteurization temperature can be set by the customer arbitrarily.

Process

Control system is based on the OMRON PLC (Japan).

The ability to connect peripherals (separators, homogenizers, deaerators).

The ability to synchronize pasteurizers capacity with the filling line capacity.

Composition:

Product tank with a level regulator.
Product stainless screw pumps.
Shell-and-tube heat exchangers (recuperation, pasteurization, cooling sections).
Hot water preparation unit based on brazed heat exchangers, safety groups, including steam lines (control and shut-off valves, condensate drains and other elements).
Stainless steel hot water centrifugal pumps.
Coil-type holding tube.
Control system based on the Omron electroautomatic equipment (Japan) with functions for setting and monitoring parameters. The system also allows to display current parameters of product processing and archive the resulting values for reports.
Pneumatic flow control circuit.

Features and advantages

Automation:

Product processing in the pasteurizer is fully automated. Control system for this process is based on the Omron PLCs (Japan). Pasteurization temperature accuracy is ensured by the implementation of automated PID-control of the temperature when operating the steam supply valve.
Initial output of the product is approved by the operator. After that control system monitors the temperature conditions of pasteurization and in case of its violation the installation switches to the circulation along the internal circuit until the preset conditions are restored.
The use of the operator's touch panel allows for a range of process visualization types in digital and graphic forms with the issuance of messages in response to operator actions and emergency situations (SKADA-system functions). The parameters of the technological process of pasteurization are set in a separate window. The pasteurizer implements the function of archiving the values of the process parameters on a customer’s preferrable form of information carrier, which makes it possible to implement the documentation of the entire technological process.
A high level of automation via the use of USB and Ethernet ports allows, at the request of the customer, to provide the ability to connect the pasteurizer to the upper-level system and the Computer-Aided Process Control System of the enterprise.
