1. How does the popcorn machine work?
Take the right amount of corn (or rice) into the pot, and seal the top cover, and then put the rice pot on the stove to rotate, so that it is evenly heated, you can burst the delicious popcorn.
This is the process of heating, the temperature in the pot is increasing, and the pressure of the gas in the pot is increasing. When the temperature rises to a certain point, the rice becomes soft and most of the water in the rice becomes water vapor. Because of the high temperature, the pressure of the water vapor is great, causing the softened rice grains to expand. But the pressure inside and outside the grain is balanced, so the grain doesn't implode in the pan.
When the pressure in the pot rises to 4-5 atmospheres, suddenly open the top cover of the explosive pot, the gas in the pot expands rapidly, and the pressure decreases quickly, making the difference between the pressure inside and outside the rice grains become larger, leading to the rapid expansion of the high-pressure water vapor inside the rice grains, and the instantaneous explosion of the rice grains becomes popcorn.
Two, what is the use of popcorn machine?
First of all, before using the popcorn machine, we need to check whether the popcorn machine is working properly, such as turning on the switch light is normally on. If it doesn't light up, then there's something wrong with the machine and we should stop using it. If the indicator light is normal, then we put a little corn in it and twist the switch to heat it. This is a preheating process, and when it bursts, it proves that it is preheated.
Operation method:
Step 1: First connect the gas bottle of the popcorn machine, turn on the heating switch, put in 50 grams of crude oil, press the rotary switch, must preheat for 3 minutes, then turn off the switch, pour out the peanut oil. According to the operation of the new machine, the service life of the pot is increased by more than two times.
Step 2: Open the function switch again (heating switch, rotary switch), and then add the special cream of popcorn rice, special corn popcorn. The pot must be preheated for 3 minutes, followed by popcorn candy, and the lid down.
Step 3: The operator should pay attention to the situation of the popcorn, such as the crack becomes smaller, a large number of rice krispies are exploded, immediately turn off the heating switch, and then continue to rotate 3 to 5 notes clock, immediately pour out.
Step 4: Clean the bottom of the pan and wipe it clean with a semi-damp towel. If the bottom of the pot is burnt, 150 ml of boiling water should be added immediately, which can flood the bottom of the pot, and then heat and rotate for about 10 minutes, so that the second pot can be exploded after the clean.
Step 5: Popcorn machine stop using, to keep the machine clean, no oil stains, no water marks. Turn off the function switch.
Two, what are the common fault maintenance methods of popcorn machine?
1. Turn on the power switch of the popcorn machine to check whether the short-circuit fuse of the device is broken;
2. Turn on the heating switch of the machine, the pot is not hot, the heating indicator is not bright, and the safety is broken. Please check whether there is a fault in the connection of the heater in the pot of the popcorn machine, the temperature controller is out of order, and the furnace plate is short circuit;
3. If the heating indicator light of the popcorn machine is not off for a long time and the temperature is too high, check the failure of the thermo-sensitive temperature controller, and adjust the Angle of the thermo-sensitive temperature controller to 180+10℃ or replace the thermo-sensitive temperature controller;
4. If the lighting thermostat switch of the machine does not light up after working, replace the bulb. If the thermostat of the popcorn machine has no temperature, check whether the floor thermostat is short-circuit;
5. If the metal induction surface of the popcorn machine is too large, please check whether there is a good grounding device.
