Industrial process steam generators play a vital role in industries ranging from food processing to pharmaceuticals. With their compact, energy-efficient design, these versatile systems support the production of food, chemicals, paper, textiles, and more. They are widely used to sanitize equipment, remove grease buildup in commercial kitchens, and support various cleaning and manufacturing processes, all while offering a cost-effective and efficient solution for industrial operations.

There are many types of steam generators, and finding the right solution depends on industry regulations and application-specific needs. At Electro-Steam, we offer a full range of industrial and commercial steam sanitization solutions. This guide explores the different types of steam generators, their common applications, and what to consider when selecting the right equipment for your needs.

The Growth of Electric Steam Generators

THE GROWTH OF ELECTRIC STEAM GENERATORS

Traditionally, boilers and steam generators have been powered by fossil fuels. However, in recent decades, global efforts to reduce carbon emissions and adopt eco-friendly energy sources have led to the development of alternative technologies. Electric steam generators are a cleaner, safer, and more cost-effective option.

Electric steam generators help organizations reduce their environmental impact without sacrificing performance. In fact, this technology delivers more efficient and reliable performance than fuel-powered options, with precision steam control capabilities. These functions make electric steam generators ideally suited for industries such as pharmaceuticals, chemical manufacturing, and food processing.

As industrial operations become increasingly automated, there is a heightened need for low-maintenance and dependable steam systems. Electric steam generators are a high-performance solution, requiring less maintenance and posing fewer safety risks than traditional fuel-based systems.

TYPES OF STEAM GENERATION IN INDUSTRIAL APPLICATIONS

Numerous types of steam from electric steam generation equipment are suitable for industrial use. Learn more about the different varieties below.

  • Saturated Steam

    Saturated Steam

    Saturated Steam

    Saturated steam generators are the most widely used variety and are especially prevalent within the pharmaceutical industry. They work by keeping steam at its boiling point. For example, steam generated at atmospheric pressure is 212 °F (100 °C). As the pressure increases, the steam’s boiling point also increases.

  • Superheated Steam

    Superheated Steam

    Superheated Steam

    Superheated steam generators create steam that is above the boiling point for a given pressure. At these high temperatures, moisture quickly evaporates, leaving behind dry steam with a moisture content of less than 1%.

  • Dry Steam

    Dry Steam

    Dry Steam

    Dry steam is in its vapor state, with no liquid present. To ensure steam remains dry, it must be effectively trapped to remove any water before the steam is transported to its end-use application. Dry steam is commonly used in food production due to its ability to eliminate bacteria and oils.

  • Wet Steam

    Wet Steam

    Wet Steam

    Also referred to as unsaturated steam, wet steam is composed of both vapor and small droplets of suspended liquid. However, the liquid does not contribute to heat transfer, since the majority of its heat is lost during the vaporization process.

  • Plant Steam or Utility Steam

    Plant Steam or Utility Steam

    Plant Steam or Utility Steam

    Also known as utility steam, plant steam is a common variety for industrial steam generation systems. While it can be generated at several pressures, it is typically saturated. In many cases, additives are incorporated to help industrial equipment resist corrosion. Due to the presence of these chemicals, plant steam cannot be directly added to products.

    Plant steam is sometimes referred to as low, medium, or high-pressure steam, depending on the pressure at which it’s distributed. However, the exact pressure for any of these categories depends on each industry and specific application.

  • Clean Steam

    Clean Steam

    Clean Steam

    The term clean steam refers to steam that is pure enough after condensation to be suitable for injection applications. Clean steam generators typically utilize saturated steam. Some of the most common applications include pharmaceutical industry sterilization, cleaning, or heating applications where product contact may occur.

INDUSTRY HIGHLIGHT: COMMERCIAL STEAM EQUIPMENT IN FOOD MANUFACTURING

Steam cleaning is a trusted and effective solution for food manufacturing operations. There are numerous types of steam equipment designed with these needs in mind.

Steam Cleaning in Food Manufacturing

STEAM CLEANING IN FOOD MANUFACTURING

Sanitation in food manufacturing requires low-moisture water vapor and high pressure to effectively sanitize, clean, and deodorize in one step. Steam cleaning equipment delivers effective results even in the most challenging cleaning applications, including food processing equipment.

Because of its high temperature, steam effectively eliminates bacteria, microorganisms, and mold on contact. It is also powerful enough to destroy grease, oils, fats, and dirt without the need for chemicals. Food manufacturing steam cleaners often use dry steam, which evaporates quickly and leaves minimal moisture behind.

Eagle Series Dry Steam Cleaners are a dependable option, with six portable models that feature dual pressure controls and a low-level cut-off. Another convenient option, the Eagle Series Brushless Conveyor Belt Cleaning Systems, reduces waste, time, and labor costs. Or for different style belts our Robotic Modular Belt Cleaning Systems for hard to clean chain-style or modular belts. We also offer Manual handheld belt cleaners that suit a range of belt widths.

Steam Cleaning Wineries

STEAM CLEANING WINERIES

Wineries must meet high standards for cleanliness. Because preserving flavor is critical, winemakers must meticulously maintain all equipment to prevent contamination. Electric steam generators meet these demands, delivering dry, saturated steam without any harmful boiler additives.

This equipment thoroughly sanitizes bottling lines, barrels, and wine bottles, leaving no trace elements behind. At Electro-Steam, we offer several winery sanitation systems, including the Menikini® Steam Master Wine and Swash™ Delux for Winery Sanitation and Barrel Cleaning. The Menikini® Steam Master Wine cleans and sanitizes many winemaking areas, such as:

Bottling Lines

For barrel cleaning applications, the Swash™ Delux is a conveniently portable option that features an ergonomic design and large-diameter rear wheels that maneuver easily within tight spaces. The Swash™ Delux is designed for easy transportation directly where needed, eliminating the need to install long, inefficient steam lines.

Key Considerations for Investing in Steam Generators

While there are many steam sanitization options to choose from, considering the following factors will help you identify the right investment for your needs:

  • Determine your steam demand. Consider the amount of steam your process requires, as well as how often you will need to access steam.
  • Consider various steam generation methods. Energy consumption is an important consideration for any application and may impact your decision-making. While steam can be generated using gas or diesel, electricity has been an effective alternative for decades.
  • Determine the right steam type. Steam quality has a direct impact on a final product’s safety and quality. It’s important to determine what type of steam is necessary for your production.
