Beer, Civilization, and Thermal Mass Flow Meters
Saturday, 16 March 2013 15:03
Thermal mass flow controllers and thermal mass flow meters help many processes that support civilization such as pharmaceutical and food production, research, manufacturing of essential goods. But what do thermal mass flow controllers and civilization have to do with beer?
In a recent New York Times article, "How Beer Gave Us Civilization", Jeffrey Kahn speculates that though early social codes such as pecking order helped keep human beings alive and multiplying, that rigid social structure also had a tendency to repress the creativity and sense of adventure that helped us grow as a species. And that is where beer comes in.
Archaelogical evidience supports the theory that human beings started cultivating grain early, not only for a food source, but to ferment for beer.
According to Kahn, beer gave early human beings, and human beings throughout history, the opportunity to relax outside of social rules making them more livable, while also giving some the opportunity to explore new perspectives in a less rigid atmosphere.
Early fermentation of beer of course was very time consuming and subject to all sorts of unknowns that could ruin the beer.
Nowadays, thermal mass flow controllers and thermal mass flow meters can be used to regulate the flow of gas and air that is so important to controlling the fermentation process to produce the quality of beer that will help keep civilization going. Thermal mass flow controllers and thermal mass flow meters have been used to contorl CO2 in the fermentation of beer from the large industrial breweries, to micro breweries, to even the home hobby brewer.
Thermal Mass Flow is happy to contribute to the progress of civilization by providing high precision thermal mass flow controllers and meters so you can relax with a beer after a hard day of following the rules and enjoy the company of your fellow human beings.

CDs and Mass Flow Meters Make Beautiful Music
Monday, 18 February 2013 15:37
What do mass flow meters meters and mass flow controllers have to do with how your CD plays and protecting it from scratches? And which side of the CD is most vulnerable to scratches?
To get the answer to those questions, we need to explore the CD itself. The CD starts off as polycarbonate plastic disc. There is a spiral track molded into the plastic that is encoded with data "pits".
But a plain plastic CD will not play. That's because a CD is read by a laser and the laser needs a reflective surface to read the data pits.
That reflective surface is what makes the CD shiny -- there is a coating of gold or aluminum that allows the laser to read the data and play your music. Mass flow controllers and mass flow meters are used to regulate the gases that deposit thin films and cure coatings for CDs and other surfaces.
Then an acrylic layer is spin coated to protect the CD. Spin coating does exactly what it sounds like -- the solution is placed on the CD and then it is spun so that the solution spreads out and creates a thin film protection. The air flow above the spin coater controls the thickness of the film and mass flow controllers and mass flow meters regulate that air flow.
Above the acrylic layer is the label varnish of the CD.
Most of us look at the bottom side of the CD when hunting for scratches. But the bottom is the polycarbonate layer. One of the toughest plastics around, polycarbonate the same plastic that goes into safety goggles. Scratches to the polycarbonate can be repaired with any CD repair kit.
It's the top, label side of the CD, that is most vulnerable. Only the label and the thin acrylic film coated on the CD with the help of mass flow controllers protect the CD on the top side. Hold your CD up to the light -- if you see light through the label then you have damage to the label side. Unfortunately this means the reflective surface is damaged and it cannot be repaired -- even if you had you own mass flow controller. So make sure you protect the label side of your CD!
Fermentation: Hot New Food Trend Heats Up With Mass Flow Controllers
Saturday, 16 February 2013 14:55
More and more food scientists and nutritionists are pointing out that the fermentation process used to produce yoghurt, sauerkraut, and many other foods form good bacteria (some of them referred to as probiotic) and enzymes that aid our digestive processes. Last year, The Art of Fermentation, a guide to do-it-yourself fermentation, landed on the New York Times best seller list. The Fresno Bee has proclaimed it one of their hot new food trends for 2013.
Mass flow controllers like those from Thermal Mass Flow are essential to the fermentation process because they regulate the aeration of the fermenters. Cell cultures need to be aerated with oxygen and carbon dioxide to promote growth. In the fermentation process, the cell culture converts starch or sugar to alcohol or lactic acid. Most people think of fermentation only in terms of beer and wine, but fermentation is used in the production of many common foods such as yoghurt, cheese, sauerkraut, pepperoni, yeast-leavened bread, and more.
Scientists and nutrionists are realizing that the probiotic bacteria that grows in the lacto-fermentation process also helps break down food in our digestive systems, promotes, supports our immune function, and promotes better absorption of vitamins and minerals such as B vitamins in our digestive tract. Some studies have even shown that this bacteria can counteract the affect of pesticides in our food.
Love Chocolate? Thank Mass Flow Meters
Thursday, 14 February 2013 18:14
For Valentine's Day, Americans purchase more than 58 million pounds of chocolate. If you are one of the lucky ones to get a heart-shaped gift, you don't just have your sweetheart to thank, but also mass flow controllers.
Mass flow meters and mass flow controllers like those manufactured by Thermal Mass Flow are an integral part of the food processing and packaging industry.
As Tri Air Testing points out, compressed air is just one of the gas applications used in chocolate manufacture. Compressed air is used to ensure consistency of taste of the chocolate and prevent contamination. Compressed air also keeps the moisture level regulated to prevent microbial growth. Mass flow controllers help regulate the flow of compressed air to ensure the rate is optimal and that adjustments can be made quickly.
Nitrogen is another gas used to made the chocolate you love. Nitrogen or other gas is injected into chocolate to create tiny bubbles and give the chocolate a pleasing texture. This injected gas must be regulated by a mass flow controller to ensure the texture is just right.
Without this kind of control, you wouldn't be so sweet on chocolate!
