Description

Technical Field

[0001] The invention discloses a production line for filling and sealing bowl dumplings, belongs to the field of food processing equipment, and specifically relates to production equipment for bowl dumplings. Background Art

[0002] Wantuan, also known as Wantuo or Guanchang, is a famous snack in Shanxi. One way to make Wantuan is to put the boiled batter in a bowl and let it cool.

[0003] Wantuan is widely welcomed by local people for its refreshing taste and rich nutritional value, so the mass production and sale of Wantuan has become a local economic feature. In the past, Wantuan was mainly produced by small workshops, with unstable production quality, short product shelf life and low production efficiency.

[0004] There are differences between the mechanized production steps of Wantuan and manual work. The mechanized operation steps can be summarized as: batter preparation, maturation, shaping and packaging. During the shaping process, it is necessary to complete the operations of feeding, shaping and packaging of Wantuan. The operation process requires stable feeding, fast shaping speed, good packaging sealing and stable production quality.

[0005] At present, there is no automatic mechanized equipment dedicated to bowl-shaped ball forming and packaging on the market. Most of the equipment requires manual participation, which leads to problems such as short product shelf life and unsightly forming. Summary of the invention

[0029] 2. The present invention adopts an air pressure shaping bag. Previously, the equipment used a heated metal block with an arc-shaped plate at the lower end. Because there is a groove on the upper end of the matured dough after filling, and a plastic film covers it, after the metal block is pressed down to shape, bubbles exist in the plastic film, resulting in poor product appearance and shortened shelf life. The main reason for the retention of bubbles is that the bubbles in the groove on the upper end of the matured dough are crushed to death by the metal block and cannot be removed. As a result, an air pressure shaping bag is used. After gas is injected, the lower end of the air pressure shaping bag first contacts the matured dough. At this time, it is in the center of the bottom bowl. The air pressure shaping bag gradually expands. The air pressure shaping bag realizes a process of gradually expanding the contact surface with the matured dough from the center of the bottom bowl to the periphery of the bottom bowl, thereby removing the bubbles in the dough and achieving the purpose of shaping the dough.

[0030] Third, the present invention adopts a filling barrel and realizes the purpose of stable single material discharge through an electric push rod. BRIEF DESCRIPTION OF THE DRAWINGS
