Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a food packaging production line. Background Technology

[0002] Due to the inherent characteristics of food, food crumbs such as breadcrumbs, jam residue, and biscuit crumbs easily adhere to the conveyor belt surface during transportation, especially when handling sticky or fragile foods such as pastries and candies. Currently, some small production lines still rely on manual cleaning, requiring workers to wipe the conveyor belt with cloths or simple tools after the production line stops. This is not only labor-intensive but also inefficient, making it difficult to meet the needs of continuous production. Some production lines equipped with cleaning devices also suffer from poor cleaning results due to design flaws. For example, using only a single brush makes it difficult to completely remove stubborn food crumbs, and large impurities can get tangled on the brush, further increasing the cleaning burden. Therefore, we are introducing a new food packaging production line. Utility Model Content
