Working Principle:

Old-fashioned popcorn machine is actually a pressure vessel, the processing of raw materials (generally corn, rice, fava beans, yellow rice and other common grains) into the machine, cover the lid. With the force lever and force tube *** with force, rotating the head screw to pressurize the cover to facilitate sealing. The popcorn machine rack to the stand, the lower with a stronger fire heating, while turning the popcorn machine through the rocker, so that the machine ingredients evenly heated and softened.

Because of the heat, the pressure inside the machine slowly rises, reaching the required pressure (different raw materials need different pressure) to stop heating, the popcorn machine twisted to one side, the mouth of the machine with a sack cover. The force tube set in the small elbow, and forcefully trigger the small elbow, so that it and the big elbow of the buckle loose, under the action of the pressure in the machine, the cover is open, the machine's high-temperature and high-pressure gas along with the processing of raw materials together with the jet out.

Compared with the common atmospheric popcorn machine now, the old popcorn machine processing raw materials adaptability, corn, rice, soybeans, broad beans, yellow rice and most other common grains can be processed, while the current popcorn machine must be used to self-popping corn, the product is relatively single.
