Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, and particularly relates to a processing production line for dorayaki. Background Art

[0002] Dorayaki, also known as gold cakes, is a kind of dessert with a baked dough wrapper and red bean paste filling. It is wrapped with two disc-shaped cake wrappers similar to honey cakes and filled with red bean paste. It gets its name because its shape is similar to two gongs put together. Because the dough wrapper of dorayaki emits a strong honey aroma and has a soft texture, it is deeply loved by people. In order to meet the needs of the vast number of consumers, in recent years, automatic production lines for dorayaki have emerged, which use assembly line operations for large-scale processing and production to supply the market demand.

[0003] For example, the Chinese utility model patent with the publication number CN203523650U discloses a full-automatic dorayaki production line. When using this equipment to make dorayaki, only the prepared batter needs to be injected onto the chain baking plate conveyor belt. The batter naturally forms a disc shape, and then through the cooperation of a baking oven, a filling injecting device, and an automatic pancake flipper, the production of dorayaki can be completed, and the processing efficiency is greatly improved. However, after using this equipment for a period of time, the oil film on the copper plate surface of the chain baking plate conveyor belt will fall off due to the decomposition or oxidation of grease. If it continues to be used, substances such as grease and sugar will adhere to the copper plate surface, resulting in the adhesion of the dorayaki dough wrapper to the copper plate. At this time, the copper plate needs to be disassembled and cleaned. After the cleaning is completed, the copper plate is reinstalled on the chain baking plate conveyor belt, and then the oil film brushing step is carried out. Specifically, the copper plate is heated to 160 to 180 °C, then the machine is run to make the chain baking plate conveyor belt start to move, and then a worker holds a long-handled brush dipped in edible oil to brush the surface of the copper plate, and then bakes for 30 minutes. Then the above-mentioned oil brushing and baking steps are repeated multiple times. Since the whole process is manually operated, not only is the efficiency low, but it is also inevitable that the oil film on the copper plate surface is unevenly applied, and then in the subsequent processing of the dorayaki dough wrapper, there will be partial adhesion or scorching, affecting the processing effect of the product.

[0004] In view of this, the inventor of the present invention has conducted in-depth research on the above problems, and thus this case has arisen. Content of the Utility Model
