Made from unleavened dough, a round rolled wrapper will be fold and sealed by pressing the edge shut, forming beautiful folds like ruffles. Aside from the folding patterns, the color of dumpling and gyoza are various. Naturally colored by fruit and vegetables, the dough was added with carrot, cabbage or spinach puree. The dyed dumpling wrapper will be eye-catching and nutritious. Colorful dumplings will be a great celebration cuisine during Lunar New Year. A good piece of dumpling wrapper must be thin and elastic enough to contain the fillings. A dumpling which cannot keep its form while boiling is a failure. Thus, the wrapper cannot be too tender nor yet too thick, but a perfect texture that is pleasantly chewy. Therefore, to reproduce such texture by machines, Hundred Machinery developed dumpling forming machines, HM-7 series, for automatic dumpling production.
