Brent LOVES fan mail! On this episode of Steam Culture, Brent answers a fan's questions on steam burns. Why do they hurt more than regular burns?
Today, Brent shows us how beef processors use steam to protect consumers against E-Coli and Salmonella. Americans consume more than 25 billion pounds of beef each year. In order to prevent the spread of disease, plants use steam pasteurization during beef processing.
Brent always finds a way to sneak in the topic of food! On this episode of Steam Culture, we are investigating processed foods and their shapes. Brent takes us through the process of food extrusion.
Today on Steam Culture, Brent shows us how steam continues to aid in the paper making process by drying the wood pulp that becomes paper.
Last week we discussed using wood pulp to produce paper products and its byproduct, black liquor. Just like coffee fuels us up on a Monday morning, black liquor fuels the paper-making process.
If you remember from last week, black liquor is created when cellulose fiber and lignin is separated from the wood chips. Wood pulp mills have used black liquor as an energy source since the 1930s.
Lumberjack Brent joins us on this episode of Steam Culture. Today, we take a look at how lumber, or "raw wood," is broken down from wood chips using steam, and eventually into wood pulp for paper products. The wood chip is made up of three main elements: water, cellulose fiber, and lignin.
The wood pulp is made by placing the wood chips into a digester, much like a pressure cooker, with water and white liquor. High-pressure steam, around 340-350 degrees, is placed in the vessel. The high-pressure steam forces the white liquor into the wood chips and the cellulose fiber is separated from the lignin. You are then left with a pulpy consistency and black liquor, which is then put into processing to produce paper products.
So, what's black liquor? You will have to wait until next week to find out! Be sure to tune in next time to see how the steam effects the black liquor and how it's used.
Today on Steam Culture, Brent shows us how steam distillation is used in extracting essential oils. Essential oils originate from plants, or botanical material, and are used in many different applications, such as cleaning and home remedies.
