The old popcorn machine shakes out the fragrance of time. Principle of old popcorn machine

Popcorn machine is a special machine for making popcorn, including mr. six hand popcorn machine, desktop hand popcorn machine, luxury commercial popcorn machine, electric popcorn machine, single pot popcorn machine and double pot popcorn machine.

First, the principle of the old popcorn machine

In the early popcorn processing, corn (multi-grains can be used) was heated in a special container, so that the corn was in a state of high temperature and high pressure, and the temperature in the pot kept rising, and the gas pressure in the pot kept increasing. When the temperature rises to a certain extent, the rice grains will gradually soften and most of the water in the rice grains will turn into steam. Because of the high temperature, the pressure of water vapor is great, which makes the softened rice grains expand. But at this time, the pressure inside and outside the rice grain is balanced, so the rice grain will not explode in the pot.

Then there was a loud bang, the cover was opened, and the corn under normal temperature and pressure was suddenly released. The gas in the pot expands rapidly and the pressure drops rapidly, which increases the pressure difference between the inside and outside of the corn kernels, leads to the rapid expansion of high-pressure steam in the corn kernels, and causes the corn kernels to burst temporarily.

That is, it becomes popcorn, and the internal structure and properties of corn will change. Nowadays, most of the popcorn is popcorn which is exploded by simply heating corn. The treatment container is no longer an early "converter", so the harm caused by lead is avoided.

Second, the use of old popcorn machine matters needing attention

According to the investigation of relevant departments, the lead content of popcorn produced by street popcorn machine is 2.45 ~ 20 mg/kg, while the lead content of cakes does not exceed 0.5 mg/kg according to national regulations. The lead content of popcorn is several times or even dozens of times that of general food hygiene standards, which will seriously harm human liver, kidney and brain tissue. In particular, children's ability to detoxify lead is weak, and eating popcorn with high lead content is prone to lead poisoning, resulting in symptoms such as loss of appetite, diarrhea, irritability, purple gums and slow growth and development.

With the development of science and the improvement of health awareness,

This kind of popcorn machine with high lead content has been unable to stand on the market and gradually eliminated by the society, but the huge profits in this kind of popcorn cannot be eliminated, and people can't let go of the delicious popcorn. Third, the popcorn formula

1, pine nut popcorn

Formula (four persons):

Four tablespoons of high-quality vegetable oil (such as sunflower oil and coconut oil is better); Four tablespoons of corn; Pine nuts100g; 2 teaspoons of cheese; 50 grams of cream; 2 teaspoons of dried basil; Garlic salt powder 1/2 teaspoons

Operation: 1. Prepare the normal popcorn without salt, and then pour it into a large bowl. 2. Bake pine nuts in an oil-free pan until golden brown, and then mix them with popcorn. 3. Slice the cheese. The cream melted in the pan. Add grated cheese, dried basil and garlic salt powder, and then stir all the ingredients thoroughly. Stir and sprinkle on popcorn and pine nuts. Stir a little and enjoy immediately.

2. Hot cream popcorn

Formula and proportion (according to four materials)

3-4 tablespoons of high-quality vegetable oil (such as sunflower seed oil); Four tablespoons of corn and 1-2 tablespoons of cream; Salt 1 tablespoon

Operation: 1. Heating the oil in the popcorn machine; 2. Pour in the corn and spread it at the bottom of the pot to separate the corn kernels; 3. Cover the pot and shake the pot back and forth vigorously every 10- 15 seconds; When the corn starts to burst, it is very important to shake the pot every 5 seconds, otherwise the corn grains below will burn.

The others won't completely explode. When only sporadic crackles are heard, remove the pot from the stove, or turn it off after cooling. Pour the popcorn into the container. Then put the cream in a still warm pot. As soon as the cream melts, pour in the popcorn. Sprinkle salt on the popcorn and enjoy it while it is hot. Note: Don't put too much salt at first, but add more salt. 3. Spice salt popcorn

Formula and proportion (4 persons)

4 tablespoons of corn; 4 tablespoons vegetable oil; A tablespoon of salt; 1-2 tablespoons cream; Dried basil 1/2 teaspoons; Dried oregano 1/2 teaspoons; 1/2 teaspoons of dried thyme; Onion powder 1/2 teaspoons; (The above spices can also be replaced by fennel salt. Production method: fennel 1 teaspoon, mustard powder 1 2 teaspoon and salt1teaspoon are mixed and mashed. )

Operation: 1. Chop the salt, spices and onions with a food processor, and mix the spices and salts evenly. 2. Prepare the ordinary popcorn, without salt, and pour it into a large bowl. 3. Melt the cream and pour it on the popcorn. 4. Put the spice salt into a large-caliber salt pot.

Then sprinkle with popcorn. My conclusion: about the principle of the old popcorn machine
