  1. How Do Indirect Steam to Clean Steam Generators Work?

    Leave a Comment

    An indirect clean steam generator is a type of high-pressure steam generator that is used to generate clean steam from an existing source of non-clean steam already present in a facility. Clean steam is commonly used in industries where sanitization and product purity and quality are paramount, such as pharmaceuticals, food and beverage, cosmetics, and biotechnology.

    Here we will look at how indirect clean steam generators work, their benefits, and some common applications and use cases for clean steam.

    Steam to Clean Steam Generators Explained

    Clean steam is created in a specialized generator called an indirect clean steam generator. These generators are made of stainless steel and carefully welded for a complete seal and no leaks. They must be operated with a dedicated supply of purified water, which is often collected via reverse osmosis or deionization processes. To be considered clean, these systems may not use a standard boiler or the facility’s regular feed water supply.

    The purified water is heated to boiling inside the indirect generator, with heat diverted from any other standard high-pressure steam generator or boiler system, and then piped to the indirect generator. It’s even possible to integrate an existing steam generator into a clean steam system to recapture excess heat generated during other processes. Neither the two water sources nor the two steams may mix, and only the heat is transferred.

    The resulting steam created from purified water is free of additives and impurities that could contaminate, alter, or damage products or equipment. Clean steam generation is often used in conjunction with clean-in-place (CIP) and sanitize-in-place (SIP) processes.

    Benefits of Clean Steam Generators

    Clean steam generators offer several benefits including:

    • Decreased Energy Consumption. Clean steam generators recapture heat energy from existing high-pressure steam sources in your facility, so they significantly reduce energy consumption.
    • Reduced Corrosion Potential. Standard steam generation systems may be treated with corrosion-inhibiting additives; however, clean steam systems are made from stainless steel, which is naturally corrosion-resistant. This eliminates the need for additives.
    • Prevention of Microbial Growth. Clean steam generation maintains temperatures that prevent microbial growth. They are also designed to eliminate standing or condensed water collection throughout the system, which keeps microbes and endotoxins out of the steam.
    • Less Risk of Product Contamination. Clean steam generators use no boiler additives, particulates, or volatile substances that may contaminate or alter products.
    • Popular Choice for Food Production. Already common in pharmaceutical production facilities, clean steam systems are also used in food and beverage production facilities to minimize potential contamination from standard steam generation methods.

    What are the Applications for Clean Steam Generators?

    Clean steam is used in these and other applications:

    • High-purity product manufacturing such as cosmetics or plant extracts
    • SIP systems for cleaning equipment following CIP processes in pharmaceutical facilities
    • Situations in which pure steam is not specified, such as non-injectable sterile pharmaceutical products or biopharmaceuticals regulated by the FDA
    • Removing oils, fats, or protein and flavoring residues from food processing equipment
    • Sterilizing equipment and instruments in hospitals

  3. Steam Applications for Different Industries

    Leave a Comment

    Because it is so versatile, steam is used in many industries. It’s common to find steam sanitization systems and specialized manufacturing processes that incorporate steam in many settings. Steam generators are an affordable and reliable source of steam ready to use, on demand.

    Below are just a few examples of steam sanitation operations and other ways steam is used in manufacturing.

    Steam Pipe Cleaning

    In-line degreasing and cleaning use hot steam to clean and maintain equipment without disrupting production or disassembling equipment. These steam pipe cleaning operations are called clean-in-place (CIP) and sanitize-in-place (SIP) systems. Examples include cleaning systems for:

    • Oil and gas industry pipes
    • Paint lines and nozzles
    • Filling lines, bottles, and conveyors in beverage bottling

    Similarly, home and commercial kitchen drains can be cleaned with steam. It removes grease and food residues from drains and grease traps without chemical cleaners or clog removers.

    Steam Applications for Different Industries

    Furniture Bending

    Steam bending is a method of shaping natural materials like wood and bamboo. The material is placed inside a sealed steam box into which steam is injected. Depending on its hardness and thickness, the material sits for several hours until it becomes pliable.

    The hot steam softens the lignans and fibers in the material so it can be formed into the desired shape. The softened material is clamped or braced against a metal form and left to cool. Once cool it will retain the new shape.

    This method does not involve glues or cuts to the material, which reduces waste and scrap. The end result is also highly aesthetic because the process does not break the wood grain or cause cracks.

    Musical Instruments

    Steam bending is also used in making wooden musical instruments such as guitars or violins. The principles of steam bending for musical instruments are very similar to those for making furniture and in woodworking.

    Heating of Railcars and Shipping Containers

    Steam is used for multiple processes that involve railcars and shipping containers. It can be used to create a heat jacket around tank cars, making it easier to pump viscous liquids like adhesives, waxes, or molasses, into and out of the vessels.

    Steam is also used to clean and sanitize rail tank cars to remove grease and residues and prevent microbial growth. Dry steam is used, so it does not leave standing or condensed water behind. Another advantage to steam cleaning is portable systems can be brought to the individual railcars instead of sending them all to a separate facility for cleaning.


    There are two ways to cure concrete with steam: under atmospheric pressure or with high-pressure steam. The size of the piece and environmental conditions determine the method. Curing under atmospheric pressure is best for large pieces or cast-in-place units. It is critical to carefully control the temperature ranges and amount of time the concrete is held at each temperature.

    Curing concrete with high-pressure steam is beneficial when high early strength is needed for quick unmolding, or when the concrete requires heat to properly hydrate. Pieces must be enclosed in an autoclave to control the pressure, so this process is limited to smaller pieces. High-pressure curing is used in areas with cold temperatures for relatively quick curing.

    It is also possible to steam clean concrete once it is properly cured and finished, such as in flooring, landscaping, or driveway applications.


    In the food industry, some types of chewy candy are coated with sugar crystals. This adds texture and flavor and prevents sticking.

    A conveyor belt moves the candies into a chamber filled with food-grade steam. This heats them just enough to partially melt the surface. They are slightly moistened by the humidity as well.

    Next, the candies are conveyed into a rotating, double-walled cylinder, along with a large amount of sugar crystals. As the cylinder turns the individual candies tumble and are coated with the sugar. Excess sugar falls through small holes in the inner cylinder and is held in the outer one so it can be used for subsequent batches.

    Once fully coated, the candies are conveyed out of the cylinder and are ready for packaging.

  4. The Different Types of Steam in Industrial Steam Generation

    Leave a Comment

    Industrial facilities rely on different types of steam to manage tasks ranging from consistent heating and processing to managing sanitation. There are many steam types available, and choosing the right one for a given application is essential. At Electro-Steam, we provide steam generation systems suitable for a wide variety of industrial steam needs. This guide will break down the different types of steam frequently used in industrial contexts to help you find the type you need for your facility.

    Types of Steam

    Learn more about the different benefits and applications of these common types of industrial steam.

    Dry Steam

    Dry steam is a type of steam with no lingering liquid in the fluid. All of the liquid has been changed to a vapor. Superheated steam, for example, has been heated to the point where no liquid remains. Other steams can act as dry steam, provided there’s a built-in method to capture the liquid before it reaches an application surface.

    Saturated Steam

    Saturated steam is a specialized type of dry steam. While there may be some liquid remaining in the vapor, it can be easily trapped and contained. In saturated steam, the steam is at boiling point (212 °F) at atmospheric pressure or higher at increased pressure levels. Because of the relationship between pressure and temperature, steam equipment can increase the boiling point by increasing the pressure.

    Saturated steam is commonly used in pharmaceutical production applications because it can provide rapid but even heating and has a high heat transfer coefficient. Operators can also fine-tune the temperature through pressure controls.

    The Different Types of Steam in Industrial Steam Generation

    Superheated Steam

    Containing less than 1% moisture, superheated steam is another type of dry steam that is hotter than its boiling point at atmospheric pressure. Superheated steam can reach higher temperatures and lower densities compared to saturated steam at the same pressure point. It can also be cooled without returning to liquid form or producing condensate.

    This resistance to becoming liquid makes it an ideal choice for applications like powering the movement of turbines. The steam can move through the nozzles and push the turbine blades, spinning the shaft that generates power, all without presenting the risk of returning to liquid and causing corrosion. It stays ultra-dry throughout its use.

    However, there are some drawbacks to superheated steam. It can have varying temperatures even at a steady pressure and has a lower heat transfer coefficient than other steams. Superheated steam won’t release latent energy until it reaches the right level of saturation. Also, because it does reach such high temperatures, it requires specialized equipment that can handle it.

    Utility Steam

    Utility steam is a type of saturated steam. Most industrial steam processes use utility steam, which contains both latent and sensible energy. Unlike Electro-Steam’s equipment, traditional boilers usually treat feed water with additives that prevent it from corroding boilers or other equipment. This steam is usually classified by low, medium, or high pressure levels. In traditional boilers, utility steam also needs to run through a filter to remove rust, condensate, and other particulates that can contaminate the steam. Even then, utility steam is usually not used in direct contact with products or food but is a means to transfer energy to the relevant process.

    While utility steam is used for boilers and a wide range of industrial applications, it’s not clean enough for culinary, medical, or pharmaceutical needs.

    Culinary Steam

    Culinary steam is regulated by the FDA to ensure any chemical additives designed to prevent rust comply with applicable health and safety regulations. It’s commonly used to sterilize surfaces used in food processing and preparation operations. Along with meeting FDA standards, culinary steam must comply with 3-A Sanitary Standards Inc. (SSI) Accepted Practice 3A-609-03, meet other company-specific policies, and use filtering systems.

    Filtered Steam

    Filtered steam undergoes a filtering process to remove additives or contaminants so it can be more safely used in sterilization applications.

    Clean Steam or Pure Steam

    Clean/Pure steam doesn’t have additives and is produced from heating purified water (RO), highly purified water (DI), or water for injection (WFI). Clean/Pure steam can be used in pharmaceutical, healthcare, and medical contexts.

    Clean steam is generated by systems that use saturated steam, and the resulting condensate can be classified as water for injection, such as saline solutions. Clean steam itself can be used in other various processes such as humidification and sanitation in which contamination cannot be present. Clean steam systems are made from high-grade stainless steel components, piping, and other non-porous materials.

  5. How Steam Has Become a Popular Way to Sanitize Food Processing Equipment

    Leave a Comment

    Dry steam sanitizing is a widely used cleaning method for a wide range of food and beverage applications. Commercial steam cleaning for food processing equipment is versatile and efficient, offering many benefits for companies across the food supply chain.

    Here we’ll look at food safety challenges and how dry steam sanitizing can help meet them.

    Challenges of Meeting Food Safety Standards

    The 2011 Food Safety Modernization Act (FSMA) sets requirements for sanitization and food safety best practices in food processing and related facilities. While cleanliness and response to foodborne illness outbreaks have always been emphasized, prevention of foodborne illness is the major priority of this legislation.

    As a result, food growers, manufacturers, producers, packagers, and transporters must do all they can to protect their products from pathogens. This is in addition to keeping equipment and facilities clean from oils and grease, food residues, insects, and allergens to avoid contamination.

    cookies on conveyor beltFood processing and manufacturing facilities, such as confectionaries, bakeries, commercial kitchens, beverage producers, and canneries, must maintain clean, sanitary equipment which is traditionally time-consuming and risks damage to equipment and injury to workers. Cleaning and sanitizing is often a multi-step process that may involve taking equipment offline, disassembling conveyors and machinery, and using intensive washing, scraping, brushing, and vacuuming techniques. Then, components must be dried and reassembled before production resumes.

    How Dry Steam Mitigates Those Challenges

    To keep up with the strict requirements of the FSMA, many facilities turn to dry steam sanitization. Unlike water or wet steam, such as the steam produced during cooking, dry steam is slightly superheated so that it contains less than 10% moisture content.

    A dry steam generator produces hot-dry steam, which is sprayed at high pressures and temperatures on and into equipment to clean and sanitize it quickly without chemicals, or in some cases, disassembly. As the steam evaporates, it leaves little to no moisture behind so that surfaces are clean, dry, and ready to be used again, much faster than traditional methods.

    Dry steam can be used for applications like:

    • Degreasing oils and fats
    • Sanitizing multiple surfaces, floors, conveyor belts, and food equipment
    • Killing pathogens including listeria and E.coli
    • Killing molds
    • Cleaning and removing residues and traces of ingredients

    There are many benefits of steam sanitization. It is especially useful in settings where equipment, ingredients, and products must stay dry like bakeries, dry and powdered ingredient processing facilities, and packaging operations. Steam reaches areas inside and around equipment that are difficult to clean with other methods. Dry steam cleaning also reduces the time for drying and reassembling equipment so it can be brought back online quickly.
