Flexible Screw Conveyor

In this case study, SP Technologies has supplied a custom-designed dosing screw that meets specific requirements for food handling and ensures an efficient process. The customer handles bags of powdered sugar that need to be emptied, as well as an oatmeal mix that needs to be transported vertically to the inlet of a filling machine.

The customer has an existing sack tipping station with an integrated sieving function that works well. Therefore, they chose to purchase only the dosing screw from SP Technologies.

Solution

The screw is designed to operate with powdered sugar 80% of the time, while the remaining 20% is spent with oatmeal mix. To meet the stringent requirements of the food industry, all product-contact parts of the screw are made from food-grade materials and are delivered with food-approved certificates.

An important customer requirement was that the screw should be easy to clean. This has been achieved by designing the screw spiral to be easily detached from the motor and pulled out from the opposite end. This solution provides optimal access to the interior of the screw tube and spiral, making cleaning quick and efficient. This is particularly important in a production environment where different food products are handled.

To ensure seamless integration with the existing system, the dosing screw is equipped with an inlet flange that can easily be bolted directly onto the existing sieve. Additionally, the screw conveyor comes with a flexible tube that can be bent to minimize the space required for installation. With a diameter of Ø67 mm and a capacity of 0.3 m³/hour, the screw meets the necessary specification requirements.

The customer has chosen to handle the suspension of the screw at the motor end themselves.

With this solution, SP Technologies has delivered an efficient and practical dosing screw that contributes to optimized and trouble-free operations for the customer.
