Overview

Scraping keeps renewing the heat transfer surface

The blades rotate with the shaft and scrape product off the heat-transfer surface to prevent build-up, suiting high-viscosity or fouling-prone food fluids.

The jacket and cylinder are cut away to show the blades on the shaft

Structure

Heat exchange built around the scraped surface

Product enters the heat exchange chamber and flows along the scraped surface; the blades keep renewing the surface as heat passes through it.

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

    Product inlet

    Product enters the heat exchange chamber smoothly.

  2. 02

    Scraper assembly

    Rotates with the shaft and scrapes product off the heat-transfer surface.

  3. 03

    Heat transfer surface

    Transfers heat indirectly between the medium and the product.

  4. 04

    Product outlet

    Sends the processed product on to the next step.

Features

Core features

  • For viscous products

    The scraping action helps handle higher-viscosity products.

  • Prevents surface deposits

    The blades continuously scrape product off the heat-transfer surface to prevent deposits.

  • Continuous process

    Feeding, heat exchange and discharge run in one continuous flow.

  • Configured to your needs

    The process is configured for your product and process requirements.
