PROCESS CYLINDERS
PRECISION-ENGINEERED FOR CRYSTALLISATION
Process cylinders are at the heart of the fat crystallisation process in scraped surface heat exchangers. These precision-engineered cylinders provide the controlled environment needed for consistent crystallisation, ensuring uniform texture, reliable product quality, and efficient heat transfer.
At Gerstenberg Services, our process cylinders are designed for durability, hygiene, and optimal performance. From weld-free construction to superfinished inner surfaces and corrugated exteriors, every feature is tailored to support long-lasting operation and smooth product flow. Whether replacing worn parts or upgrading your system, our cylinders help maintain high-capacity, stable production with minimal downtime.
Process cylinders for scraped surface heat exchangers
Process cylinders are the core components of scraped surface heat exchangers (SSHEs), forming the chamber in which fat crystallisation takes place. Their primary role is to provide controlled heat transfer, allowing fats to cool and crystallise uniformly. This controlled process is essential for achieving consistent texture, plasticity, and product quality in margarine, shortening, and specialty fat applications.
Working in combination with scrapers, the process cylinders ensure continuous mixing and efficient heat exchange while preventing product from sticking to the inner surface. This interaction supports stable crystallisation, even temperature distribution, and reliable operation under demanding mechanical and thermal conditions.
Key design features that enhance quality and durability include:
- Weld-free construction: Eliminates welded flanges, reducing the risk of cracking or damage to the chrome surface and extending service life.
- Corrugated exterior: Optimised to improve heat transfer efficiency, supporting precise temperature control during crystallisation.
- Superfinished inner surface: Minimises product adhesion, improves flow, and supports hygienic operation.
- High-grade, durable materials: Chrome protects against wear and corrosion in continuous production environments.
- Extended operational lifetime: The robust design reduces maintenance frequency and supports long-term, reliable performance of the SSHE.
Together, these design features ensure that process cylinders deliver reliable crystallisation performance, consistent product quality, and long service life, making them a critical component in high-performance scraped surface heat exchanger systems.
Designed for Perfector units
Gerstenberg Services process cylinders are specifically engineered for use in Perfector scraped surface heat exchangers, ensuring a precise fit and reliable performance across all applications.
Compatibility and sizing
Process cylinders are available in all sizes corresponding to the full range of Perfector SSHE types. Each cylinder is fully interchangeable with existing Perfector components, allowing for straightforward replacement without modifications to the machine. Precise manufacturing tolerances ensure correct mechanical alignment and seamless integration into the production line.
Optimised for Perfector SSHE performance
The cylinders are designed to work in perfect harmony with the scraper and rotor systems used in Perfector units. This ensures stable crystallisation conditions, efficient mixing, and consistent heat transfer throughout operation. By maintaining optimal temperature control and flow behaviour, the cylinders help deliver uniform product quality while reducing mechanical stress on surrounding components.
Compared with older or non-optimised alternatives, these design improvements improve operational reliability, minimise unplanned downtime, and support consistent, high-quality production over the long term.
Durable materials, improved versions – full interchangeability
At Gerstenberg Services, all redesigned parts are manufactured using optimised materials to improve durability, wear resistance, and service life under demanding production conditions.
Despite these design and material enhancements, all components remain fully interchangeable with standard Perfector parts. This means upgrades or replacements can be carried out without line modifications, redesigns, or compatibility concerns, ensuring straightforward maintenance and minimal disruption to production.
