Snow cake is a puffed food made of selected rice. Crunchy, sweet and diverse in taste, most of them are made from selected rice and other foods through baking, heating and other processes.
When the grain is placed in the expander, with the progress of heating and pressurization, the water in the grain is overheated, and the grain itself becomes soft. When it reaches a certain high pressure and opens the expander cover, the high pressure quickly changes to normal pressure. At this time, the overheated water in the grain will suddenly vaporize and explode strongly, and the water molecules can expand about 2000 times. The huge expansion pressure not only destroys the external shape of the grain, It also breaks the internal molecular structure of the grain, cuts the insoluble long chain starch into water-soluble short chain starch, dextrin and sugar, so that the insoluble substances in the snow cake are reduced and the water-soluble substances are increased.
