When was the hand-cranked popcorn machine invented in mr. six, China?

China mr. six hand-exploded popcorn machine was invented in Britain in the late19th century. So it is also called English popcorn machine. After the electrification era in the 20th century, it did not prevail in the west, and then it began to prevail in China, especially in the 1960s and 1980s.

There is a black popcorn machine like a cannon on the fire, and the master shakes it while pulling the bellows. With a loud noise, a cloud of white smoke rose, hot popcorn filled his pocket, and the attractive aroma made his mouth water-these are many beautiful and interesting memories of China's childhood after 1980s.

This traditional popcorn machine is the "cannon hand-cranked popcorn machine", and making popcorn with the old popcorn machine is also called "popcorn" figuratively.

Working principle:

The old popcorn machine is actually a pressure vessel. Put the processing raw materials (generally corn, rice, broad beans, yellow rice and other common grains) into the machine and cover it. Turn the head screw with the same force as the booster rod and the booster tube to pressurize the sealing cover. Put the popcorn rack on the bracket, heat the lower part with strong fire, and turn the popcorn machine by hand to make the raw materials in the machine soften evenly.

Due to heating, the pressure in the machine gradually increases. When the required pressure is reached (different raw materials need different pressures), stop heating, twist the popcorn machine to one side and cover the machine mouth with a sack. The booster is sleeved on the elbow, and the elbow is pulled hard to loosen the buckle of the elbow. Under the pressure in the machine, the cover is opened, and the high-temperature and high-pressure gas in the machine is ejected together with the processing raw materials.

Compared with the common atmospheric popcorn machine, the old popcorn machine has wide adaptability, and most common cereals such as corn, rice, soybeans, broad beans and yellow rice can be processed. However, the current popcorn machine must use self-exploding corn, and the products are relatively simple.
