Scraped surface heat exchangers for efficient heat transfer of viscous food products like peanut butter, mayonnaise, margarine & dairy. Ideal for heating, cooling, chilling, crystallization, freezing & vaporization.

Key Features & Benefits:

  • Alloy Stainless Steel Heat Transfer Cylinder: Constructed with high-quality stainless steel for exceptional corrosion resistance, hygiene, and longevity.

  • Replaceable Mechanical Seal:  Easy-to-maintain seal design minimizes downtime and ensures a leak-free operation.

  • Self-Aligning Scraper Blade Mechanism: The self-adjusting scraper blades continuously remove product buildup from the heat transfer surface, maximizing efficiency and preventing fouling.

  • Insulated Coolant Chamber: Enhanced insulation minimizes energy loss and maintains precise temperature control within the coolant chamber.

  • Easy-to-Clean Sanitary Design:  The hygienic design includes smooth surfaces, rounded corners, and removable parts for thorough cleaning and sanitation.

  • Gear Drive with Chain Sprocket: The robust gear drive system provides reliable power transmission and enables precise speed control of the scraper blades.

  • Compact Design: The overall reduced length of the heat exchanger saves valuable floor space in your processing facility.

  • Handles Challenging Products:  Our SSHEs are specifically designed to handle a variety of difficult-to-process products, including those that are:Viscous
    Heat-sensitive
    Prone to crystallization
    Sticky
    Contain delicate particulate matter

  • Superior Scraping Technology: Robust Industrial's patented rotating scraping technology continuously removes fouling material from the heat transfer surface during processing. This ensures consistent heat transfer efficiency and minimizes downtime due to cleaning.

  • Gentle Product Handling: The scraper blades are designed for gentle product handling, preserving the quality of shear-sensitive products while maximizing heat transfer.

  • Enhanced Efficiency: The large flow area and reduced pressure drop of our SSHEs contribute to exceptional heat transfer efficiency and energy savings.

  • Enhanced Heat Transfer Efficiency: The continuous scraping action maximizes heat transfer by preventing product buildup on the heat transfer surface.

  • Versatile Applications: Suitable for both heating and cooling applications.

  • Customizable: Can be tailored to specific product needs and processing requirements (e.g., peanut butter, margarine, mayonnaise, fruit pulps, dairy products).

  • Ease of Maintenance: The self-aligning scraper blades and replaceable mechanical seal simplify maintenance procedures and reduce downtime.

  • Consistent Product Quality: Precise temperature control and efficient heat transfer ensure uniform product quality and minimize the risk of product degradation.

Versatile Applications:

  • Food Processing: Ideal for products like peanut butter, chocolate, spreads, sauces, fruit purees, dairy products, and more.

  • Chemicals:  Efficiently handles viscous chemicals, heat-sensitive resins, and products prone to crystallization.

  • Pharmaceuticals: Provides precise temperature control for heat-sensitive pharmaceutical ingredients and products.

  • Health and Beauty: Gently processes creams, lotions, gels, and other viscous personal care products.

Robust Industrial Expertise:

With decades of experience in thermal engineering, Robust Industrial understands the unique challenges of different industries. We tailor each SSHE to meet your specific product and process requirements, ensuring optimal performance and reliability.

A scraped surface heat exchanger (SSHE) For Cooling or Heating of Viscos Material Like Peanut Butter, Spreades, Sauses, Margarine, mayonnaise and other uses rotating blades to continuously scrape the inside of a cylinder wall to remove product and ensure uniform heat transfer. The blades are attached to a moving shaft or frame and can be made of rigid plastic to avoid damaging the surface. The product enters the cylinder in a corkscrew pattern in the same direction as the blades, which helps to preserve product quality by reducing shear and pressure drop. The blades also create a thin film on the heat transfer surface, which increases the surface area available for heat transfer.

What Is Scraped Surface Heat Exchanger Used For?

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. They are ideally suited for products that are viscous, sticky, that contain particulate matter, or that need some degree of crystallization.
How Scraped Surface Heat Exchanger Works ?
In scraped surface heat exchanger there are scraping blades on a rotating shaft .Alternatively, the blades move against the heat transfer surface under the influence of the rotational forces.
What is the purpose of a Scraped Surface Heat Exchanger?
Heat exchangers can be use for controlled crystallization, pasteurization and sterilization, gelatinization, freezing, cooling, heating and even evaporation Mostly viscos material.
