Description

Technical Field

[0001] This invention relates to the field of twisted dough stick production and processing technology, specifically to a method and apparatus for preparing non-fried twisted dough sticks. Background Technology

[0002] Twisted dough sticks are a traditional Chinese fried snack. They are made by twisting two or three strands of dough together and deep-frying them. However, fried dough sticks are considered to cause internal heat and are not healthy, which does not meet the dietary habits of modern consumers. With the continuous development of automated production technology, the requirements for automation in the production of twisted dough sticks are getting higher and higher. Non-fried twisted dough sticks are mainly made using micro-puffing and hot air drying processes. When forming twisted dough sticks, multiple extruded long strips of dough need to be kneaded together. During this process, the dough sticks stick to the surface of the reciprocating board, resulting in a large amount of dough adhering to the board. This leads to poor kneading results and difficulty in cleaning the dough sticks during subsequent kneading processes. To address this, we propose a method and apparatus for preparing non-fried twisted dough sticks. Summary of the Invention
