After a day, Zheng Tao took Zheng San and drove back to Jade City, bringing with them several pieces of equipment.
He introduced them to Zhou Yi one by one.
Zheng Tao first pointed to a simple machine with two metal funnels, one above the other, and a lever on the side and said, "This is a hand-cranked threshing machine that costs 4 gold. The beans from Chicken Head Town and Oasis Town are threshed using this, eventually shelled, leaving only the bean kernels, which can be sold after drying."
"Just toss the peanuts in there and stir the rod to crack the shells. Although it's manually operated, unlike in Mechanical City where it just needs an Energy Pack for propulsion, the good thing is you can adjust the speed and the screen inside, maintaining the breakage at a relatively low percentage."
"The second step is roasting the peanuts because that makes the oil fragrant. Jade City can just ramp up the temperature, so I didn't buy any additional iron drum for mixing and heating."
