Flottweg Belt presses

Belt 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.

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.

The press rollers ensure the best possible dewatering of the mash. The mash cake is subjected to a steady increase in pressure by rollers of varying diameters. This facilitates a rapid and efficient juicing process. 

The Flottweg Extraction System supports this process with its sophisticated design: An L-profile roller ensures efficient and even centrate discharge, resulting in fast dewatering, a high yield, and top-quality products.

Special press nip rollers, such as edge zone rollers, increase the pressure at specific points and optimize dewatering. This is especially beneficial for special products such as brewer’s grains. The belt alignment brings the belts together in the wedge zone and then guides them over the L-profile roller and the press rollers.

The Flottweg belt press features a safe and hygienic design. It meets the highest standards of durability, operational reliability, and cleanliness. The entire machine, including rollers and bearing brackets, is made of stainless steel.

Compared to conventional presses, where rollers are often plastic-coated, the consistent use of stainless steel facilitates easier and more thorough cleaning.

Thanks to an intuitive and automated control system, the Flottweg belt press can be operated safely and efficiently with minimal personnel effort.

An integrated recirculation system collects the process water produced during cleaning and reuses it several times, reducing fresh water consumption.

Service costs also remain low, as the belt press is equipped with only a few durable bearings and standardized replacement parts. This makes it much easier to maintain compared to hydraulically operated tank presses. Energy consumption is low thanks to an efficient drive motor with a maximum output of 1.5 – 5.5 kW, which further reduces operating costs.
