Hygienic design meets maximum yield: The Flottweg Belt Press
Efficient solids processing system for the highest requirements in the food industryBelt presses offer proven technology for the effective dewatering of mash, pomace or grape marc. They reliably separate materials into their liquid and solid components. In the food industry in particular, fast, reliable, and hygienic processing is a decisive criterion for preserving valuable ingredients.
The Flottweg belt press effortlessly meets these requirements and ensures outstanding juice quality, particularly in the manufacturing of fruit and vegetable juices. Its performance is impressive, as is its hygienic design: It is made of stainless steel and is equipped with an automatic belt cleaning system that operates during production. A CIP system is featured on all machines. These measures ensure maximum cleanliness and efficiency.
The belt press is indispensable in the manufacturing of starch or plant-based milk alternatives, as it achieves a high dry solids content and significantly reduces transport and total drying solids costs. A belt press is typically part of a multi-step process. Belt presses often interact with other processes, such as those involving decanter centrifuges.
Flottweg offers the optimal solution for every process requirement and supports customers in the selection and integration of manufacturing facilities. The Flottweg belt press features a hygienic stainless steel design, efficient dewatering processes, and low maintenance costs. It ensures optimal, resource-saving production with high yields.
Optimal dewatering
- L-profile roller: Discharges centrate efficiently and evenly
- Press nip rollers: Increases pressure at certain points for better dewatering
- 2-Belt press: Achieves higher yield (75–85% total dry solids)
Flexible adaptation thanks to Flottweg Extraction System
- Coordinated press zones: Slow pressure increase allows gentle dewatering
- Flexible feeding system: Wide application of the solid cake, optimized by experience and trials
How the Flottweg belt press works
A feed roller distributes the mash continuously and evenly on the lower belt. The cake height and width can be flexibly adjusted to the respective product to ensure optimal product infeed. Various feeding systems ensure precise dosing and even distribution of the mash.
In the wedge zone, the two belts come together. The upper belt applies slow and even pressure to the product, resulting in a stable mash cake. This coordinated press zone facilitates a gentle increase in pressure, which causes the different mash structures to be dewatered gently and effectively.
Dewatering is performed in the press area, initially by an L-profile roller. The roller ensures rapid liquid drainage from both sides of the cake.
Press rolls with different diameters follow. The product is efficiently dewatered through a combination of continuously increasing pressure and shear forces. Optionally, press nip rollers can be used to further optimize dewatering, achieving an even higher yield. During operation, after removal of the pomace, high-pressure nozzles continuously and reliably clean the filter belts of residues, ensuring stable, continuous operation.
