Effective Use of Huhnseal Mechanical Seals for chocolate applications in Next-Generation Twin-Screw Pumps by CSF-Inox and Scraped Surface Heat Exchangers Produced by MBS

The product-contact parts in CSF-Inox pumps are designed with AISI 316L stainless steel, featuring a surface finish of less than 0.8 microns, guaranteeing maximum food safety and corrosion resistance. The support structure, entirely made of AISI 304, provides a solid foundation to ensure proper pump operation.
MBS's scraped surface heat exchangers (SSHEs), including the Hercules project, represent the utmost excellence in the industry. Collaboration with the University of Parma has allowed MBS to determine precise heat transfer coefficients and study materials in relation to various tested products. This led to the development of a proprietary calculation program to optimize the efficiency of the produced exchangers. These are particularly advantageous for high-viscosity products with suspended particulates, optimizing the production process and significantly improving the exchange coefficient.

The Crucial Importance of Mechanical Seals in MBS Exchangers and CSF Twin-Screw Pumps

The precision and effectiveness of mechanical seals, as highlighted by Huhnseal's Knife Edge solution for chocolate and anhydrous creams, play a vital role in ensuring the continuity of the production process. In contexts where protein chains tend to create thickness at the seal ring interface, adopting appropriate solutions like the Knife Edge seals is essential to prevent potential adhesion issues and maintain high-quality standards.

Combined Benefits of CSF-Inox and MBS Solutions

The synergistic integration of chocolate-optimized mechanical seals within CSF-Inox twin-screw pumps and MBS's Hercules scraped surface heat exchangers offers numerous advantages:

  • Maximum Food Safety: mechanical seals tailored for chocolate, combined with the design of CSF-Inox pumps and MBS exchangers, ensure maximum safety in food production. 
  • Efficiency and Longevity: using Huhnseal K-E seals in CSF-Inox pumps and MBS exchangers for high-viscosity products increases process efficiency, extends equipment lifespan, and optimizes production. 
  • Optimal Handling of Complex Products: Integrated solutions optimally handle complex products, maintaining material integrity and simplifying maintenance operations.
