Kombinator® SHCW - Scraped Surface Heat Exchangers

The Gerstenberg Schröder Kombinator® 250 SHCW is a compact, high-capacity, high-pressure scraped surface heat exchanger. It is designed for the pasteurization of mainly low-fat spread emulsions which contain a high amount of protein and stabilizers to avoid fouling of the emulsion on the inner surface of the tubes and allow for longer and more efficient production time. It provides high performance, minimal downtime, and easy maintenance.

Kombinator® 250 SHCW: Efficient Heating and Cooling for High-Quality Food Products

Product Overview

Designed for cost-effective production of high-quality emulsions with steam heating and water cooling capabilities.

Model Variants

Available in short version (250S) and long version (250L) to accommodate various processing requirements.

Engineering and Design

Dual Thermal Exchange System

Features one or two steam-heated tubes and a double-walled water-cooled coil for improved heat transfer and cooling efficiency.

Heating & Cooling Media Compatibility

Supports cooling water, chilled water, brine, glycol, steam, or hot water. Each tube includes automatic temperature regulation.

Compliance and Build Quality

Built to PED pressure regulations with a robust, hygienic design suitable for demanding industrial environments.

Function and Principles of Operation

Thermal Exchange Mechanism

Emulsion is heated to pasteurization temperature via steam tubes; centrifugal scrapers ensure heat transfer and prevent buildup.

Post-Heating Cooling Process

Double tube coil above heating tubes rapidly cools emulsion with water flowing inside and outside the tube wall for maximum efficiency.

Capacity

Maximum Throughput

Up to 8.8 tons per hour.

Key Advantages

Product Quality and Hygiene

Consistent product texture and performance
Stainless steel AISI 316 contact parts meet food-grade standards
Sealed, corrosion-free casing with full insulation

Heating and Cooling Efficiency

Corrugated chilling tubes reduce compressor oil buildup and improve uptime
Automatic temperature control per tube for accurate heat profiling
Double tube coil design ensures rapid cooling

Operational Versatility and Maintenance
