Contherm® Scraped-Surface Heat Exchanger
The Ultimate Food Heat Transfer Solution

Contherm® – The ultimate food heat exchanger
Today convenience food plays an important role in peoples’ lifestyles. However, fresh flavor and pleasing texture at an affordable price are critical qualities to the modern consumer. This presents a challenge to food manufacturers, particularly with prepared foodsmade from delicate raw materials or with consistencies that demand special processing.

Why a scraped-surface heat exchanger (SSHE)? Many prepared foods prevent optimal heat transfer because of their consistency or content. For example, food or products with the following characteristics can quickly block or foul certain types of heat exchangers: Viscous Ketchup, mayonnaise, chocolate, fruit piefilling, gravy and sauces, whipped/aerated products, peanut butter, pizza sauce, pudding, salad dressing, salsa and taco fillings, sandwich spreads, mechanically deboned meat, gelatin, scrambled eggs, baby food, ointment, lotions, mascara and candle gels. Crystallizing/Phase Change Coffee/tea extracts, icings and frostings, lard, sugar concentrates, margarine, shortening, spreads, beer and wine.Crystallizing/Phase Change

The Heart of the System Scraped-surface heat exchangers are at the heart of many modern continuous and semi-continuous processes of various food products. Also at the heart of many of today’s systems are the Contherm SSHEs, which have earned the trust of many producers of today’s food products. Optimizing thermal efficiency Continuous production is a prerequisite formodern food processing because it promotes: • high throughput • uniform heat transfer • better economy

How it works
• Product enters the cylinder through the lower tangential port and flows upwards through the cylinder. • Simultaneously, media travels in a countercurrent flow through the narrow annular channel. • Rotating blades continuously remove product from the cylinder wall to ensure uniformheat transfer to the product. • A coil in the annulus increases media velocity, adding to the heat transfer efficiency. • Product exits the cylinder through the upper tangential port. • Product flow and rotor speed can be varied to suit the properties of the product flowing through the cylinder. • Numerous configurations of the Contherm are available. By varying materials of construction, featuresand options, you can customize your SSHE to meet your requirements.

Contherm design features and options ensure reliability, flexibility and maximum runtime, adding up to increased lifetime economy and return on investment.

Tangential head

Tangential product head design • Product enters the cylinder under the rotor in a corkscrew pattern in the direction of the rotor to assure gentle product treatment. Product enters and exitsthe cylinder in the same direction as the turning rotor, maximizing product integrity and quality. This gentle handling is a must for products such as pie fillings, fruit preserves and soups and stews. Aseptically sealed units • Minimize the risk of microbial contamination • 3A Approved • A closed-system design keeps air, bacteria and foreign material out • Remove the risk of contamination with...
