Automatic Chicken-Plucker (Aug, 1929)
If you want to see a rather disturbing, yet captivating, video that shows how insanely scaled up modern food-animal production has become, watch this clip from the movie Samsara. If you’d like a video with a more vintage feel, check out the amazing “This is Hormel” from the always awesome Prelinger Archives at Archive.org.
Application of the principle of the vacuum sweeper lias been applied to this device shown below so that it automatically plucks fowl in a few minutes time. The bird is held against a rotary “grill”, enclosed in a cylinder, through which suction passes as in a sweeper. As the feathers are separated by the air current, they come in contact with a metal plate, equipped with several catchers which pluck the feathers and fine down when rotating.
Portable Unit Puffs Cereal Grains (Dec, 1936)
I’m kind of amazed I haven’t seen one of these still in use in Portland. It seems like artisanal breakfast cereal would be very popular here. Salted caramel hemp puffs anyone?
Portable Unit Puffs Cereal Grains
DESIGNED especially for light manufacturing, a new machine recently introduced by a Portland, Oregon, manufacturer
converts wheat and rice grains into a delightful breakfast cereal. Four quarts of dry grain when exploded makes about one bushel of breakfast food. The machine can be operated by one person and will produce $120 worth of merchandise per day. An electric motor operates the device.
COWS EAT SAWDUST AND THRIVE ON STRANGE DIET (Dec, 1930)
I found the 1922 preliminary report on the process along with the 1926 study done on the composition, digestibility and feeding value of the hydrolyzed sawdust.
From the 1926 article: “The method of treatment consists in cooking the sawdust under 120 pounds pressure with dilute sulphuric acid, which converts
a portion of the cellulose and allied substances into sugar. The liquor resulting from the digestion together with the washings from the undigested sawdust residue is neutralized with lime and evaporated to a thick syrup, which is mixed with the dried residue. The product is then ready for feeding. It is a dark brown somewhat powdery meal with a slightly sweet woody odor and a woody flavor.”
Before anyone tries to draw comparisons with “Fresh Horizons” bread from the 70′s, that high fiber bread contained wood pulp and NOT sawdust. And it was banned in Canada.
COWS EAT SAWDUST AND THRIVE ON STRANGE DIET
Making cows eat sawdust, and like it. is the feat of the Forest Products Laboratory, Madison, Wisconsin. A process has developed that converts the fiber of the woody pulp into food for cattle by treatment with heat and chemicals. Its immediate application is seen in utilizing the sawdust that was formerly a useless by-product of lumber camps. Tests indicate that cows and other livestock thrive on the sawdust diet.
My Profits Are Mushrooming (May, 1950)
Check out a the slightly more refined process used today. (video)
My Profits Are Mushrooming
A small corner in your basement and a bit of fungus mold are all you need to start a mushroom farm and grow yourself a big-money business.
By Corwin Fred
BACK in 1929 I knew nothing about running a business. I did know, however, that I wanted one of my own, and I realized it had to be some enterprise I could start without much cash—and learn as I went along.
A few months later the profits had really started mushrooming from my own business—growing and selling mushrooms. As a mushroom farmer, I’ve been squeezed into some tight corners—but I’ve squeezed out again.
