You can mix powdered ingredients such as cornstarch, rice bran, mashed rice, oil meal, soybean meal) with a little water.
clean so that it can be held back into a fist.
This compression is the use of physical and pore-shaped compression conditions. The temperature in this type of compression
can be up to 125-150 degrees Celsius, under pressure for about 20 seconds, humidity from 20-24% makes the food agglutination
more sticky. Thereby, this mixture shows high plasticity and is pressed through the press table with high pressure.
When the pellet leaves the press board, with high pressure, the steam in the component evaporates to form air pockets in the tablet
food. When cooled, they generally only make up about 0.25-
0.3 g / cm3 so the pellet can be floating.
