Food Culture

Mini juicy bun, xiao long bao, or often known as soup dumpling, as its name implies, has meat juices sealed in the wrapper after steaming in a bamboo steamer. Chinese buns usually filled with minced pork and chopped vegetable; then, what's the difference between mini juicy buns and other kinds of buns? Mini juicy bun is made with unleavened and thin wrapper that becomes translucent after steaming, revealing stuffing and meat juices inside, whereas other buns are mostly made with leavened dough and thicker. The mini juicy buns are often dished up along with a small dish of soy sauce and ginger shreds sometimes white or black vinegar is added.
Din Tai Fung, a world-renowned xiao long bao restaurant in Taiwan, is famous for the 18-folds crown on top of each xiao long bao. Due to Din Tai Fung's success, the dish of xiao long bao becomes popular around the world and is served in many Chinese restaurants.

The forming machine could not cut and form stuffed dough tube into individual mini juicy buns.

The recipes of handmade foods are not all suitable for machines to manufacture foods. For example, heat generated by machine operation makes dough warmer than that kneaded by hand. Therefore, the ingredients of dough need to be adjusted to prevent dough from degrading.

The problem in this case is that the mini juicy buns could not be cut and formed. Our engineer extruded the dough tube to check the extensibility of the dough. He found the dough is too hard, ...→To get more information? Please Click Contact Us Below

  • Put the stuffing into the stuffing hopper.
  • Put the dough into the dough hopper.
  • The cylindrical stuffing is extruded by the stuffing pipe of HLT-700XL.
  • The dough tube is extruded by the dough pipe of HLT-700XL.
  • The cylindrical stuffing is encrusted with the dough tube while they are formed.
  • The stuffed dough tube is cut and formed into individual mini juicy buns with 9 folds on top by the EA-100K (the updated model: EA-100KA) forming machine.

The shutter unit of the EA-100K forming machine is designed with great ingenuity to prevent dough from sticking.

In order to prevent dough from sticking, our engineers minimized the contact time and surface when the shutter unit cut and form the products. Although there is no doubt that the structure of the shutter unit has a significant impact on production, the shutter speed is the key to success. At the moment the shutter opens and closes, a product is formed perfect and pleasing. (Note: EA-100K is no longer available. The updated model is EA-100KA.
