Overview

Scraped surface heat exchange for continuous sterilization

The blades keep renewing the heat transfer surface so the product heats and sterilizes evenly. Suited to high-viscosity food liquids or those that tend to stick.

The middle cylinder is cut away to show the blade rotor and heat transfer surface

Structure

A continuous process from heating to cooling

Product moves along the scraped surface through heating, holding and cooling, with the blades keeping the heat transfer surface stable.

Heating / cooling mediumProductThe blades turn with the shaft and continuously scrape product off the cylinder wall
  1. 01

    Preheating section

    Brings the product smoothly into the following temperature stages.

  2. 02

    Sterilization section

    Completes sterilization by indirect heat exchange.

  3. 03

    Holding section

    Holds the process temperature; the exact time is confirmed for each process.

  4. 04

    Cooling section

    Brings the product to the temperature needed for the next step.

Features

Core features

  • For viscous products

    The scraping action suits higher-viscosity food liquids.

  • Stable heat transfer surface

    Continuously renews the heat transfer surface, limiting the effect of product build-up.

  • Continuous sterilization

    Heating, holding and cooling follow one another in sequence.

  • Configured per process

    The process is defined by the product and the sterilization requirements.

application

Suitable products

  • High-viscosity products
  • Products with fruit pieces or fibre
