Spee-Dee Packaging Machinery, Sturtevant, Wis., created a testing lab that can simulate production runs, giving customers assurance that their product will meet desired fill rates and accuracies.
The goal of the test lab is to duplicate a customer’s specific application to ensure the proper amount of product head pressure is present in the hopper during the test run—simulating what would occur during a normal run in the customer’s plant.
During testing, granular product is carried in a bucket elevator, while powders are transported via a vacuum conveyor to a second floor mezzanine. This 2,400-square-foot testing lab features a variety of ancillary packaging equipment, such as conveyors, checkweighers and in-feed systems. High-speed cameras record the tests to show characteristics of the product charge and any problems such as drip or string out. Customers who are not able to observe the test in person can see the results on video. Vertical form-fill-seal machines can be used in the testing process if the customer desires.
To test high-speed rotary fillers, the test lab uses a 150-foot test loop for rigid containers, which can fill up to 250 cans per minute.
Spee-Dee also provides detailed results and a full summary, including filling accuracy, speed and other parameters of each test. The summary includes a report of any filling challenges encountered and Spee-Dee’s recommendations of how to alleviate those challenges.
