flow pack

The focus of this case study is to show how Delfin Industrial’s vacuum cleaners helped achieve the customer’s goals when integrated on flow pack machinery.



The customer is an original manufacturer leading in high-quality solutions to process, mold and pack chocolate. In order for the company to obtain its reputation, there is significant importance that the high-quality equipment work to its best ability, therefore able to process, mold and pack chocolate.



For this customer, there were two problems that needed to be solved. Problem #1 was that the product did not stay still during the transport phase. Since it would not stay still, this would cause imperfections and dust to spread both in the production line and in the work environment. Problem #2 was that the customer needed to find a solution to remove the extra air before sealing the product. This was important to the customer because removing the air would help guarantee the product to be the best quality and preserved well.
