Milk Pasteurization


Milk Pasteurization: thermal processing lines for food products with plate and/or tubular heat exchangers

HTST, ESL and UHT lines

Sordi designs and manufactures thermal processing plants for milk pasteurization.

The milk pasteurization plant lines are available in different types of systems: HTST pasteurizing lines, super pasteurizing lines, UHT sterilizing lines. The lines are pre-assembled on platform and may be automatic or semi automatic.

The control systems for milk pasteurization plants are equipped with PLC Siemens with supervision HMI (Human Machine Interface). The heat exchangers can be plate type (standard or free-flow plates) or tubular (corrugated pipes).

The line for milk pasterization plant is skid-mounted and it is composed of:

  • Balance tank
  • Sanitary centrifugal pump with filtre
  • Plate, or tubular, heat exchanger with high thermal recovery
  • Tubular holding
  • Hot water preparing set
  • Flow diversion valve
  • Control panel system

It is also possible to include in-line the degaser, the homogenizer, the separator or other machines necessary for specific processings, which will be regulated and controlled by the same control panel.

This milk pasteurization plants may process plain or flavoured milk, creams, ice-cream mix, fruit juices and generally all types of food fluid drinks.

HTST thermal processing

Pasteurizing plants for milk, fruit juices and different drinks, composed of:

  • Balance tank
  • Sanitary centrifugal pump
  • Plate/tubular heat exchanger with thermal recovery
  • Tubular holding
  • Hot water preparing set
  • Flow diversion valve
  • Over pressure pump
  • Control panel system

It is also possible to include in-line degaser, homogenizer, separator or other machines necessary for specific processings.

ESL Pasteurizing thermal treatment

During the ESL thermal treatment milk is heated and skimmed. Skim milk is microfiltered while cream is pasteurized at high temperature. Skim milk and cream are re-mixed at the requested fat content value. Standardized milk is then pasteurized and homogenized.

Milk is filled by ultra clean filling machine and has a 21 days shelf-life at 40 C.
