Case: Efficient Screening of Granulate Products at a Confectionery Manufacturer
Challenge
A leading manufacturer in the confectionery industry needed a precise and efficient screening solution for some of their granulate products.
The production flow involved various types and sizes of products, making it essential to accurately separate between:
-
Oversized product, which needed to be rejected
-
Standard product, which made up the desired end product
-
Fines and smaller particles, which had to be removed
The customer required a solution that could handle the different fractions with high precision while also ensuring easy cleaning and maintenance – a crucial factor in the food industry. After screening, the final product is packed into big bags or boxes.
Solution
Before selecting the screening solution, a series of practical tests were carried out in collaboration with our partner, Separtech.
The customer sent samples of two product types, which were tested using different mesh screens to determine the optimal configuration.
Based on the test results, it was decided to supply a Separtech No GAP URS065 Ø1500 mm vibratory screen. The machine was configured with:
-
Two screen decks for sorting into three fractions: oversize, standard product, and fines
-
A Quick Screen Change system with a hydraulic lifting device, allowing for fast and easy mesh changes – ideal for cleaning or product changeovers
-
NO GAP screen design, which eliminates any gaps between the screen mesh and the screen frame, preventing small product particles from getting trapped
-
A blank deck (blind plate) for situations where a product type doesn’t require screening – allowing the material to bypass the screening process and go directly to the packaging line
This configuration offers high flexibility and minimizes production downtime.
Result
With the new screening solution, the customer has achieved:
-
Precise and consistent separation of the product into three fractions
-
Improved operational reliability and uniform product quality
-
Reduced time for screen mesh changes and maintenance, enhancing overall production efficiency
The close collaboration between the customer, SP Technologies, and Separtech ensured a well-tested and fully documented solution that meets the high standards of the food industry – both in terms of product quality and hygiene.
