Fan for suction of a strawberry belt

Developing a new machine is not easy and needs to be tailor-made for a process. Our client had a request to develop a machine to automatically remove the crown from strawberries. The strawberries were placed on a belt and had to be sucked with their crown into a small hole. Several strawberries on a belt until it was full and then a knife would automatically run under it and top the strawberries. It was not easy to determine the suction here. But thanks to our engineering department, we were able to go on site and measure what would be needed in terms of suction power. This enabled us to select a suitable fan for our customer.

Solution using stainless steel centrifugal ventilator with pull-out system

In the end, we designed very high-quality stainless steel centrifugal fans with a pull-out system to remove the impellers for easy cleaning. As we use robust impellers, the hinges naturally had to be sufficiently heavy duty. We therefore provided two mounting brackets on the swing-out system and the motor plate was equipped with three quick-release fasteners. We also provided a condensation drain with G½” internal thread. This stainless steel fan was equipped with a 5.5kW 2-pole WEG motor. The fan was manufactured entirely from stainless steel 304, after which it was shot-blasted to give all welds a perfect finish. The fan was fully TIG-welded, which is also very important in the food industry.
