Complete Quality Control SystemA Solution for Filling for the Food Industry
Filling containers requires very fast, precise and repeatable results. Inconsistency in
weighing can be costly – either giving away product by overfilling containers or risking
fines by not meeting Weights and Measures standards or net weight legislations.
A large US pudding and yogurt manufacturer was facing this exact problem monitoring
their fill weights during packaging.
Fill weights were inconsistent and fill-er operators were not performing theStatisticalQualityControl(SQC)processcorrectly.Thecustomerneededamethodbywhichtheycouldmonitorfillweightsand attributes such as product appear-ance, labeling, and expiration date ona real-time basis enabling immediateadjustments to be made to their proc-esseswhenrequired.

Safety and integrity of your products is at the very heart of your brand’s reputation.
When sanitation practices are insufficient, bacteria can harbor and thrive in equip-
ment used in food processing. Also scales may harbor and transfer the bacteria to products.
When this occurs, scrupulous sanitation must occur to eliminate potential hazards.
