Understanding the craped surface heat exchanger working principle
In a scraped-surface heat exchanger, product enters the cylinder from the bottom and moves upward, while a heating or cooling medium circulates in a counter-current flow through an annular channel.
Key Process Features:
- Rotating blades continuously scrape the cylinder wall, optimizing heat transfer.
- The product moves in a corkscrew motion, aligning with the rotating assembly to minimize shear and pressure drop.
- Adjustable product flow and rotor speed allow customization based on viscosity and process requirements.
This scraped wall heat exchanger design ensures uniform temperature control, preserving product integrity in sensitive applications.
More possibilities with Contherm®

As the only provider of both single and double-wall scraped-surface heat exchanger solutions, Alfa Laval offers unmatched flexibility. Each Contherm® heat exchanger is customized for the intended application, maximizing efficiency, processing capacity, and profitability.
Viscous product processing
The Contherm® range supports continuous processing for a wide variety of high-viscosity challenging products. Whether dealing with moderate or extremely thick fluids, there’s a Contherm® solution for your needs.
Example Applications: ketchup, mayonnaise, hummus, chocolate spreads, gravies, peanut butter, pizza sauces, puddings, salad dressings, mechanically deboned meat (MDM), gelatine, shampoos, and more.
Heat-sensitive product handling
Scraped-surface heat exchangers are an ideal solution for heat-sensitive products that tend to cause fouling in other types of heat exchangers. With the most complete range available, Alfa Laval can support customers with any challenging heat-sensitive product need.
Designed for delicate, heat-sensitive formulations, Contherm® HP prevents burn-on and maintains product stability.
Example applications include: liquid and scrambled egg products, meat emulsions, fruit preparations and fruit purées, cream cheeses, whey proteins, and more.
Crystallizing products and applications with phase change challenges
Preserving taste, color and/or texture is a particular challenge for manufacturers of products that can undergo crystallization. We work with your business to find the optimal Contherm® solution to fit your production.
Example applications include coffee/tea extracts, icings and frostings, sugar concentrates, margarines, shortening, spreads, gelatine broth, lard, fondant, biscuit creams, solvents, fatty acids, petroleum jelly, beer and wine, and more.
Products with particulate matter
Contherm® solutions are always built to the specifications of the target duty. With its customizable scraping system, Contherm® HP efficiently processes both particulate and non-particulate materials without compromising integrity.
Your Contherm® can be adapted to meet the demands.
Example applications include: meat, chicken pieces, fish meal, pet food, jams and preserves, yoghurt with fruits, a variety of fruit preparations, rice pudding, vegetable pieces, and more.
Sticky product processing
Many heat exchangers encounter limits when handling process fluids that are sticky. For Contherm®, however, it’s never a problem. The complete Contherm® family can support a full range of mildly to extremely sticky products, from foods to beauty products and more.
Unlike traditional surface heat exchangers, Contherm HP is engineered for handling sticky, highly viscous substances with ease.
Example applications include: caramel, cheese sauces, lecithin, processed cheese, confectionery, yeast extracts, gums, gelatine, mascara, toothpaste, starch, and more.
