Description

Glutinous rice ball cutting and appliqué production line and production technology

Technical field

The invention belongs to the technical field of glutinous rice dumpling processing equipment, and specifically relates to a glutinous rice dumpling skin cutting and applique production line and a production process.

Background technique

Tangyuan is a spherical food made of glutinous rice flour. It usually has fillings and is cooked and eaten with soup. There are more and more types of fillings for glutinous rice balls, including black sesame filling, peanut filling, fruit filling, flower filling, cheese filling, meat filling, etc.

In order to realize the automated production of glutinous rice balls, glutinous rice dumpling machines and glutinous rice dumpling production processes have been developed rapidly. For example, the Chinese patent document with the authorization announcement number CN112655730B discloses "a fully automatic rice dumpling machine", the Chinese patent document with the authorization announcement number CN215013503U discloses a "fully automatic rice dumpling machine", and the Chinese patent document with the authorization announcement number CN220255524U discloses "A glutinous rice ball forming machine" and so on. The above-mentioned glutinous rice dumpling machines are all capable of producing traditional spherical shaped glutinous rice balls. In order to further shape the glutinous rice balls, such as applying decals on the glutinous rice balls, artificial methods are usually used to paste the shaped decorative pieces on the glutinous rice balls. Decorative pieces are usually flour products. First, the dough is made. The thickness of the dough is usually 1 to 2 millimeters. The dough can be made by using the skin-making device in the dumpling machine in the prior art. Then, decorative pieces that meet the requirements are cut out on the dough manually. The decorative pieces can be in various shapes such as leaf shape, fish shape, oval, triangle, pentagon, etc. Workers then manually paste the decorative pieces onto the glutinous rice balls. At present, the above-mentioned processing process is a semi-automatic production line, that is: the production of glutinous rice balls and the making of dough use automated mechanical equipment; while cutting out decorative pieces from the dough and attaching the decorative pieces to the glutinous rice balls are done manually. Therefore, semi-automated production lines have shortcomings such as low efficiency, poor consistency of finished products, and high labor costs.
