Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, in particular to an on-site cleaning control system. Background Art

[0002] In industries such as food and beverage, and pharmaceuticals that have extremely high requirements for hygiene standards, Clean-in-Place (CIP) technology is the core link to ensure the cleanliness of the production line. Traditional CIP systems clean tanks, pipes and other equipment through predefined cleaning procedures, but their design is mainly for a single product or a fixed production process, and it is difficult to adapt to the needs of flexible production. With the increasing market demand for multi-variety, small-batch production, production lines need to frequently switch between different products, resulting in a significant increase in the combination of cleaning objects, cleaning parameters and process complexity.

[0003] At present, the CIP cleaning process mainly relies on manual judgment of which equipment needs to be cleaned and the corresponding CIP systems are turned on one by one. If a certain equipment needs to be cleaned multiple times, the operation must be repeated multiple times. This method relies on manual operation, and the operator may clean the wrong equipment, wasting production time, or may not clean enough, so that the equipment starts production without being cleaned, causing quality accidents. Summary of the invention
