Puffed Rice Forming Machine
The so-called puffed food is mainly made of cereals, potatoes or beans as raw materials, which are made by pressurizing, heating or squeezing to change the structure and volume of the food and present a porous and fluffy taste. However,
what kind of magic power does the puffing effect have that can transform
ordinary corn, wheat, potato, rice and other raw materials into round,
triangular, spiral, and star shapes, and they taste crisp and crispy? To
understand the effect of puffing, you can start with the principle of popcorn.
The raw material of popcorn is dry corn kernels with a hard shell, which
functions like a pressure cooker. Once heated, the moisture inside the corn kernels is heated and the pressure gradually increases. The weaker shell becomes
a pressure outlet, and the high hot water component instantly becomes due to the
pressure drop at the outlet. The steam expands and stretches the corn husk, and
then pushes out the soft gelatinous batter made by gelatinizing starch particles
in the corn kernels.
Since the water vapor in the corn kernels is instantaneously expanded in more
than one place, they are like small bombs inside the corn, exploding out at the
same time, causing the internal tissue of the corn to produce many small
bubbles, and the overall volume becomes larger. After the corn pops, the small
bubbles fuse together and cool and solidify. The water vapor evaporates at the
same time, resulting in a decrease in water content. The originally squishy
gelatinous batter turns into blossoming beautiful white popcorn. Therefore,
heating food materials containing starch and water, and sometimes even
pressurizing them, causes the water vapor between the food materials to open up
the whole tissue of the food. This series of reaction processes is puffing. The
common popcorn on the street is also made using the same principle, the
difference is that the popcorn does not have a hard shell, and the source of
pressure is a special pressure cooker. The unique pounding sound effect of
popcorn is because when the pressure cooker is opened, the pressure in the pot
is suddenly released, and the water in the rice grains instantly turns into gas,
and the internal high-pressure gas is too late to release.
