Kombinator® 250S - Scraped Surface Heat Exchangers
The Gerstenberg Schröder® Kombinator® 250S is a compact, high-pressure scraped surface heat exchanger for margarine and shortening processing and other high-viscosity fats & oils applications, offering superior crystallization performance, maximum uptime and easy maintenance.
FEATURES
Compact Power for High-Viscosity Product Processing
The Gerstenberg Schröder® Kombinator® 250S is designed to meet growing industry demand for high-quality, high-viscosity products with low production costs. Ideal for margarine and shortening processing, the 250S also supports the production of low-fat spreads, butter, butter blends and other thermally processed foods that require precise temperature control and consistent crystallization.
Reliable Performance in a Compact Design
This compact scraped surface heat exchanger features up to four flangeless, corrugated, multi-layer chilling tubes—each with its own cooling system—and operates using ammonia or Freon refrigerants. Every tube is equipped with automatic temperature regulation to ensure accurate cooling across a range of formulations. The Kombinator 250S is engineered for reliability, durability and adaptability, with a hygienic design that complies with international food industry certifications.

The crystallization takes place in the scraped surface heat exchanger (SSHE) which is the heart of the crystallization line. The product is pumped into the chilling tubes, cooled and crystallized. Constant centrifugal force keeps the scrapers pressed against the interior walls of each tube, ensuring highly efficient removal of crystallized product—regardless of its consistency.
