Steam Facts
Did you know that superheated steam is one of the safest non-chemical cleaning agents? In addition to being safe, steam is an incredibly green technology. It aids cleaning at many levels as good superheated steam above 300C is better for drying (generally 260C is the approximate inversion temperature). The high-temperature super-heated steam is important in the antimicrobial use. All steam for such uses should be checked with chemical and heat strip indicators. Please contact Bayzi for assistance on where to acquire sterility indicators. For more information about steam generators please click here.

Some notes on the hardness of water.

Water Hardness definition.
Grains/Gallon or Parts/Million Description
less than 1.0 less than 17.1 soft
1.0 to 3.5 17.2 to 60 slightly hard
3.6 to 7.0 61 to 120 moderately hard
7.1 to 10.5 121 to 180 hard
10.6 & over 181 & over very hard
More (tallow) soap is required for washing in hard water than in soft water. A water softener
may be required if grains/gallon of water-hardness exceed 3.
Does high-pressure enable the outcome of a steam or chemical reaction for H2O? The short answer is seldom especially above 100°C. Long Answer.
What is more important is having an open-continuous system like the OAB, HGA where molecules of H2O are able to enable more of the desired reaction because of continuous production. This is a steam generator.
Today, high quality superheated steam is finding many applications in drying, cooking, proper and complete bacterial inactivation, fraking, chemical processes engineering, tablet making, mixing and materials processing. Very high temperature steam at one atmosphere packs the proper punch required for these applications while minimizing the dangers of using high pressure boilers. Given below are the standard steam diagrams for process design. This type of superheated steam is used in applications that have a critical need to reduce the process time. Superheated steam often offers a higher heat transfer coefficient and high enthalpy content that enables many unique uses. When at a high temperature, especially above the inversion temperature, such steam is often considered as a non-toxic antimicrobial agent. Superheated steam at a high temperatures also offers superior reaction for example in energy reactions such as bio-fuels, reforming, hydrogen production, ammonia production, and denaturing, all with rapid heat transfer kinetics.
What is Humidity?
There are several ways to describe the humidity of the air (a term used generally only below 100C, at 1 atmosphere conditions). At high temperatures it is more accurate to talk about Specific Humidity (also called the humidity ratio) which is the mass of water vapor present in a unit mass of dry air; that is, it is the ratio of mass of water vapor to the mass of dry air. Below the saturation temperature (e.g 1 bar, 99.6C) one often uses the term Relative Humidity when steam is mixed with air. Relative humidity is a ratio that compares the amount of water vapor in the air with the amount of water vapor that would be present in the air at saturation. Relative humidity is given as a percentage: the amount of water vapor is expressed as a percent of saturation. Example, at 25oC and 1 atmospheric pressure, the corresponding specific maximum humidity is about 3% although the the relative humidity is at 100%. Endotoxins, microbes and bacteria are known to be inactivated by heat and H2O. All MHI superheated steam productions produces high temperature steam that during production encounters temperatures in excess of 500C. The steam output temperature and condition of humidity are controllable as discussed below for several models.
Vapor pressure measures the water vapor content of the air using the partial pressure of the water vapor in the air. (Pressure may be expressed using a variety of units: pascals, millibars, pounds per square inch (psi), among others). The gases in the atmosphere exert a certain amount of pressure (about 1013 millibars at sea level). Since water vapor is one of the gases in air, it contributes to the total air pressure. The contribution by water vapor is rather small, since water vapor only makes up a few percent of the total mass of a parcel of air. The vapor pressure of the water in the air at sea level, at a temperature of 20oC, is 24 mbar at saturation (about 3% by volume).
