Scraped Surface Heat Exchangers

Overview

Our scraped surface heat exchangers (SSHEs) are designed for handling viscous or fouling fluids, such as those in the food, pharmaceutical, and petrochemical industries. A rotating scraper or blade continuously removes deposits from the heat transfer surface, which offers several benefits compared to conventional heat exchangers:

  • Improved Heat Transfer Efficiency: SSHEs help prevent fouling or scaling on the heat transfer surface by constantly scraping off the accumulated deposits. This maintains a clean surface for heat transfer, resulting in higher overall heat transfer efficiency and reduced fouling-related heat transfer resistance. This means that an SSHE can maintain its heat transfer performance for longer periods without frequent cleaning, reducing downtime and increasing process efficiency.
  • Enhanced Product Quality: In industries where product quality is critical, such as food and pharmaceuticals, SSHEs can provide significant benefits. The continuous scraping action helps to prevent product buildup on the heat transfer surface, minimizing the risk of product degradation, fouling, or contamination. This results in improved product quality, consistency, and purity, making SSHEs ideal for processing sensitive or high-value products.
  • Increased Process Flexibility: SSHEs are versatile and can handle a wide range of process fluids, including viscous, particulate-laden, and fouling-prone fluids. They are also capable of handling a wide range of operating conditions, including high temperatures and pressures. This makes SSHEs suitable for a variety of applications, from heating or cooling viscous food products, such as sauces and confectionery, to processing petrochemicals, pharmaceuticals, and specialty chemicals.
  • Reduced Maintenance and Downtime: Fouling is a common issue in heat exchangers, and it can lead to decreased heat transfer efficiency, increased energy consumption, and increased maintenance and downtime. SSHEs with their built-in scraping action can help reduce fouling, which in turn reduces the need for frequent cleaning and maintenance, leading to decreased downtime and increased productivity. This can result in significant cost savings and improved process reliability.
  • Energy Savings: Fouling on heat transfer surfaces can increase the energy requirements for heating or cooling processes, as it reduces the effective heat transfer area and increases the temperature difference across the exchanger. By minimizing fouling, SSHEs can help reduce energy consumption and operating costs, making them more energy-efficient compared to conventional heat exchangers.
  • Compact Design: SSHEs are often designed to be compact, which means they can be easily integrated into existing process lines or systems without requiring extensive modifications. This makes them ideal for retrofitting into existing processes where space is limited.

Why Select Genuine Spart Parts for Your Scraped Surface Heat Exchanger

Because Downtime is the Enemy of Efficiency

Some scraped surface heat exchanger replacement parts may seem attractive due to a low price, but only looking at the initial cost may leave you vulnerable to unforeseen costs later. There are reasons that alternative, “might fit” parts cost less, including the possible use of lower quality materials or modifying important manufacturing steps, such as polishing or coating. This could result in a part not lasting as long.

For some applications, this might not matter if the user does not mind making frequent replacements. But for scraped surface heat exchanger applications such as in the food or pharmaceutical industries, polishing and coating are critical to sanitary performance and cleanability. A lower quality finish on a part could increase the risk of bacterial growth and contamination of the final product.

Why Use Genuine Spare Spares in Your Scraped Surface Heat Exchanger

If you install a third-party aftermarket scraped surface heat exchanger part into your original scraped surface heat exchanger, this will void your scraped surface heat exchanger’s warranty. That’s because all our parts are engineered to work seamlessly within the process functions they were designed for. High precision means high efficiency. Even the tiniest bit of lag or play can impact your scraped surface heat exchanger’s efficiency, become a potential safety hazard for your employees, or cause a process line to go down until a proper replacement part is ordered and installed.

Scraped Surface Heat Exchangers FAQs

A scraped surface heat exchanger is a type of heat transfer equipment that is used to efficiently transfer heat between two fluids. It consists of a cylindrical shell that contains a rotating shaft with blades or paddles attached to it. The blades scrape the inner walls of the shell as they rotate, effectively removing any buildup or fouling that may occur on the heat transfer surfaces.

This scraping action helps to maintain a high heat transfer rate by preventing fouling, which can reduce the heat transfer coefficient and increase energy consumption. The scraped surface heat exchanger is commonly used in the food and chemical industries, where viscous or fouling fluids are processed, such as chocolate, margarine, or polymer melts.

The design of scraped surface heat exchangers can vary depending on the application, and may include multiple tubes, internal or external heating or cooling, and different materials of construction to meet specific process requirements.

A scraped surface heat exchanger is commonly used for processing viscous or fouling fluids that can cause fouling or scaling on the heat transfer surfaces. Some of the typical applications of a scraped surface heat exchanger include:

  • Food Processing: It is used for processing food products such as chocolate, cheese, butter, margarine and other viscous or semi-solid foods.
  • Chemical Processing: It is used for processing various chemicals, such as polymers, resins and adhesives, which are prone to fouling.
  • Pharmaceuticals: It is used for processing various pharmaceutical products, such as ointments and creams, which require gentle heating and cooling.
  • Petrochemicals: It is used for processing various petrochemical products, such as waxes, oils and lubricants, which require high-temperature processing.

In all these applications, the scraped surface heat exchanger is used to transfer heat efficiently and maintain a high heat transfer rate while preventing fouling or scaling on the heat transfer surfaces. The scraped surface design helps to ensure that the heat transfer surfaces remain clean and free from any build-up, thereby improving the overall efficiency of the process.

There are mainly two types of scraped surface heat exchangers:

  • Batch Scrape Surface Heat Exchanger: In this type of heat exchanger, the product is heated or cooled in a batch mode. The batch mode of operation allows for high heat transfer rates and good temperature control.
  • Continuous Scrape Surface Heat Exchanger: In this type of heat exchanger, the product is continuously fed into the heat exchanger, heated or cooled, and then discharged at a steady flow rate. This type of heat exchanger is ideal for processes that require a constant flow of product.

Both types of scraped surface heat exchangers can have different configurations depending on the specific application requirements. Some of the common configurations are:

  • Single Shaft: It consists of a single shaft with blades that rotate inside a cylindrical shell.
  • Dual Shaft: It consists of two shafts with blades that rotate in opposite directions, creating a mixing action that enhances the heat transfer.
  • Triple Shaft: It consists of three shafts with blades that rotate in opposite directions, providing high shear mixing and improved heat transfer.
  • Multiple Stage: It consists of several stages of heat transfer with separate scraped surface heat exchangers connected in series, providing high thermal efficiency and improved temperature control.
  • Custom Designs: Custom-designed scraped surface heat exchangers can be created to meet specific application requirements, such as high-pressure applications, specific materials of construction, or specialized surface finishes.
