  1. Indirect Clean Steam Generators in Biopharma and Pharma

    Leave a Comment

    Like all electric steam generators, Indirect Steam Generators effectively sterilize components by injecting clean steam into piping, autoclaves, or other laboratory and production equipment so pharmaceutical professionals can easily control conditions of their processes.   Learn more about the advantages of indirect clean steam generators, the applications of clean steam, and what to look for in a high-performance generator.

    Benefits and Applications of Steam Cleaning in the Biopharma and Pharma Industries

    Green capsule medicine pill production line, Industrial pharmaceClean steam simplifies the process of maintaining a sterile facility by providing a no-contact yet reliable clean, even for tools with complex profiles, edging, or small interiors. The following are the top advantages of steam cleaning in the biopharma and pharma industries:

    • Prevention of contaminant entry. Unlike traditional steam, clean steam is sterile at the point of vaporization and clean steam generators do not have vulnerable entry points for biological or chemical contaminants to enter. This successfully maintains steam’s purity during the full sterilization procedure.
    • Protection against pathogen growth. The extremely high temperatures of clean steam can kill all types of microorganisms that are contamination concerns in pharmaceutical processes, and also help prevent their initial growth by handling condensate buildup.
    • Corrosion resistance. Metal parts are prone to corrosion when in the presence of traditional utility steam. Clean steam, however, has corrosion-inhibiting properties that counteract this risk. As a result, clean steam increases the life span of equipment.

    Steam sterilization has many beneficial applications within the biopharma and pharma industries, particularly in  biopharmaceutical manufacturing. The goal is to keep the bacteria, yeast, or animal cells present in manufacturing environments from contaminating healthcare materials, products, and equipment. Steam sterilization, SIP and CIP can assist professionals in these industries by controlling and maintaining sterile environmental conditions, allowing safe manufacturing of things such as ophthalmic products, parenteral, injectable solutions, and more. 

    Pharmaceutical companies commonly use clean steam generators for sterilize-in-place (SIP) procedures, which utilize steam to sterilize and clean pharmaceutical instruments, equipment, and surfaces between production cycles. Pharma professionals also use clean steam generators to support humidification processes for clean rooms, lyophilizers, and sterilizers.

    Electro-Steam’s Steam-to-Clean Steam Generators’ Operational Characteristics

    Steam-to-clean steam generators, or indirect clean steam generators, from Electro-Steam Generator Corp. capitalize on the functionality, steam output, ease of use, and footprint that standard electric steam generator varieties provide but improve upon their operation by using “house steam” energy that converts deionization (DI) or reverse osmosis (RO) water into clean steam. In contrast to the all-electric generators that use submerged electrical elements, the indirect clean steam units save on energy consumption as they use steam that your facility is already producing and then repurposes it.

    Electro-Steam’s indirect generators function at pressures ranging from 9 to 90 psi.  They use an electric control circuit of 120VAC to regulate steam input, output, water level, and operating pressure within the generator automatically. Requiring only a total amperage of only 15 amps—with an 8-amp Full-Load Amperage (FLA) rating—eliminates the need for 3ph power.

  3. Steam Quality

    Leave a Comment

    Steam quality plays a vital role in steam system operations in the pharmaceutical industry, which uses two main types of steam: industrial steam and pharmaceutical steam. Industrial steam is used as a utility in boilers and does not come into contact with process equipment. It often contains additives to protect pipes and boilers from corrosion and precipitation.

    Pharmaceutical steam is produced from pure, treated water so that it contains no volatile additives like hydrazines and amines. This steam is used to sterilize process instruments. Steam sterilization of pharmaceutical equipment largely depends on the quality and purity of the steam. Low-quality steam can negatively impact the sterilization of your system.

    This blog will discuss the importance of steam sterilization, factors that affect steam quality, and how to calculate steam quality.

    Why Is Steam Quality So Important?

    High-quality steam plays an integral part in killing microorganisms during equipment sterilization. The best steam is neither too dry nor too moist. Wet steam—steam that contains too high a moisture content—can weaken the steam’s ability to transfer its latent heat energy to the equipment and result in longer sterilization times. Dry steam—also called superheated steam—lacks the appropriate moisture content to kill microbes and uses higher temperatures than necessary, which can damage the equipment.

    Poor steam quality can reduce heat transfer efficiency by as much as 65%. The liquid in steam contains about 16% of sensible energy, while its latent energy is around 94%. Therefore, poor-quality steam delivers much less usable energy to the process steam equipment.

    Furthermore, low-quality steam can cause premature valve failure. As the steam passes through the valves, the excess moisture causes buildup that erodes the insides of the valves. Wet steam can also lead to water hammer in steam systems not accustomed to handling additional liquid. Water hammer can reduce the steam system’s lifespan and, in some cases, rupture the pipes.

    How Do You Calculate Steam Quality?

    Steam quality is the proportion of vapor in a liquid/vapor mixture. A steam quality of 0 contains 100% liquid, while a steam quality of 100 contains 100% steam.

    Here’s a formula to calculate steam quality:

    Steam quality = Mvapor/(Mliquid + Mvapor)

    Most heat transfer and sterilization methods assume steam quality of 100 is in use, but sometimes operators do not regularly or properly use steam quality testing equipment to monitor steam quality in real time. With low-quality wet steam, free droplets can form in the process stream, causing corrosion and mechanical damage. One way to assess steam quality is to open a steam valve, releasing some steam into the atmosphere. If the steam is nearly invisible, it is more saturated and thus better quality. If the steam is white, it contains a higher moisture content and is not suitable for sterilization.

  4. Why Food Processing Manufacturers Prefer Dry Steam for Cleaning and Sanitizing

    Leave a Comment

    While washdowns are a popular choice for cleaning debris from surfaces, this process leaves surfaces wet which can cause bacterial growth, is time consuming, and causes significant downtime. Dry steam, which is created in an industrial dry steam cleaner by heating water in a closed chamber instead of a flow-through coil, uses less water, evaporates quickly, and gets into cracks and crevices where water can’t reach. Sanitation in the food industry is commonly achieved with dry steam cleaning because it’s quick, cost-effective, and reliable. 

    Dry Steam for Cleaning & Sanitizing in Food Processing

    Food processing facilities are often water-sensitive, so traditional wet cleaning methods are time-consuming and labor-intensive—if they’re possible at all. More and more facilities are using dry steam sanitation, taking advantage of the power of high-temperature, low-moisture steam to clean and sanitize conveyor belts and other industrial machinery.

    With temperatures above 240°F, the dry steam kills mold, bacteria, viruses, and other microorganisms while removing grease, dirt, and residue. It evaporates quickly, so you’re left with a surface that is clean, dry, and sanitized. 

    Why Food Processing Manufacturers Prefer Dry Steam for Cleaning

    Food processors are held to strict standards for cleanliness and sanitation as a matter of safety and product quality. Dry processing facilities in particular face additional challenges, because the slightest bit of moisture can ruin baked goods, dry ingredients, powdered drink mixes, seasonings, coffee, and more. Wash-down cleaning methods are simply not feasible in these facilities.

    Because dry steam has an extremely low moisture content, it eliminates the risk of moisture exposure in dry processing facilities and can easily remove oily substances often found in food processing facilities. All types of food and beverage processing facilities trust dry steam for cleaning and sanitizing work surfaces, hoods, vents, floor drains, walls and ceilings, conveyor belts, and more. 

    Dry steam can also be used to clean switches, sensors, small components, and moving parts that are impossible to reach with other cleaning methods. Common cleaning methods require equipment to be disassembled creating downtime which can be costly. With dry steam cleaning, in most cases, you won’t need to take the equipment apart to clean it. Not only does this save time in the cleaning process, but it also reduces downtime for the facility and helps the manufacturer maintain production and meet deadlines. 

    Benefits of Dry Steam Cleaning for Food Processing Facilities

    Food processing facilities that use dry steam cleaning enjoy many benefits, including:

    • Time Savings: Because equipment doesn’t have to be dismantled, the cleaning process is faster than other methods and reduces downtime and labor costs. 
    • Environmental Friendliness: Dry steam requires less water than traditional cleaning methods reducing water consumption and waste water creation.
    • Chemical-Free: Limiting exposure to chemical fumes and residue creates a safer environment for your employees and prevents product contamination. Reducing or eliminating your use of chemical cleaners is environmentally friendly, as well, as you’ll produce less plastic-container waste.
    • Efficient: High-temperature dry steam dissolves oils and residue and kills bacteria and other microorganisms on contact. High heat and low moisture properties reduce downtime by leaving cleaned surfaces dry and ready for immediate use. It’s a fast, efficient process that reduces labor and downtime. 

    If your facility is water-sensitive, or if you simply want to save time and money while reducing your environmental impact, dry steam cleaning is the solution you’ve been looking for. At Electro-Steam, we’ve surpassed clients’ expectations since 1952. Our industrial dry steam cleaners are trusted in food processing facilities, manufacturing plants, car washes, bottling facilities, HVAC systems, and more. We have several systems designed to meet your specific application. Contact us to learn more about the advantages of dry steam cleaning, or request your free demo today. 

  5. Steam Sterilization in the Pharmaceutical Industry

    Leave a Comment

    There are certain industries where cleanliness and sterilization must be a priority; the pharmaceutical industry is one of them. Pharmaceutical workers rely on steam cleaning for fast, efficient sterilization. 

    Pharmaceutical applications use clean steam, which is created from treated water of either RO or DI quality. They also commonly use autoclaves, or steam cleaners, which are machines that use pressurized steam to kill viruses, bacteria and other microorganisms on the items placed inside the sterilizer chamber. These autoclaves can be as small as a microwave, making it easy to keep them in labs, clinics, and other medical facilities, or even to transport them from room to room or facility to facility. Hospitals and busy labs may use larger models that can sterilize many pieces of equipment at the same time. 

    What Is an Autoclave and How Does It Work?

    In an autoclave, pressurized steam reaches temperatures of 250-273 °F (115–134 °C), which is hot enough to kill mold spores, viruses, and bacteria. The higher the temperature, the less time the items must remain inside the autoclave. For example, at 250 °F, the items would have to remain inside for 15 minutes to ensure sterilization; at a temperature of 273 °F, they would only need to stay for three minutes. Autoclaves are common in pharmaceutical, medical, dental, and laboratory facilities, and they’re used to sterilize tools, equipment, and even waste.

    Autoclaves work by removing the air around the items that are to be sterilized, which allows the steam to penetrate the surface of the objects. There are two ways to achieve this with two specific types of autoclaves:

    • Gravity Displacement Autoclaves: Steam is heavier than the air in the chamber, so the machine injects the steam—which forces the air out via the drain vent. It’s the simpler of the two types of autoclaves, and it’s common in labs and for use with biowaste. It does, however, take longer to work than a prevacuum autoclave, because it takes time for the air to leave the chamber or some air may get trapped inside; the Centers for Disease Control and Prevention mention that 10 pounds of microbiological waste would require at least 45 minutes in a gravity displacement autoclave at a temperature of 121°C.
    • Pre Vacuum Autoclaves: A vacuum removes the air from the chamber first, then the steam is injected. This allows the steam to go right to work on the objects inside. This is the preferred type of autoclave for use with large, porous objects. 

    Items in the Pharmaceutical Industry That Can Be Sterilized With Steam

    Because steam sterilization is cost-effective, non-toxic, and time-efficient, autoclaves are common in a variety of medical and pharmaceutical facilities. In hospitals, they’re more likely to be called steam sterilizers, while in laboratories they’re more often called autoclaves; however, they are the same thing. 

    While items made of polyethylene, polyurethane, and polystyrene cannot be steam cleaned, many of the other tools and devices in use in medical facilities can be sterilized in an autoclave. This includes respiratory therapy and anesthesia equipment, dental instruments, sharps containers, and more—basically, anything that is heat and moisture resistant. Microbiological waste can be decontaminated in an autoclave, but it typically requires more time inside. 

    Sterilizing equipment in an autoclave is fast and efficient, and it doesn’t require a team of people devoted solely to cleaning after everyone else has gone home for the day. Instead, technicians and medical practitioners can sanitize as they go along, ensuring their equipment is always free from potential disease-causing microorganisms.
