Waste extraction and recycling in food processing and packaging

The food production and packaging process of food places enormous hygienic demands on the machines and their environment. To avoid contamination of the food products, dust and other process waste needs to be removed as quickly as possible from the process line. Our high-performance extraction and disposal systems are used for:  

  • waste extraction and disposal in food processing such as bakery products, sweets, fruit, vegetable, coffee, tea, spices etc.
  • waste extraction and disposal in the food packaging process such as beverage cans, PET bottles, folding boxes, beverage boxes, foils etc.
  • extraction of cutting waste and chads from packaging
  • disposal of the edge trim, margin strips, cutting waste in the paper and foil processing sector
  • extraction and briquetting of milling waste and paper dust
  • disposal of used packaging material in logistic packaging and distribution centres
  • handling of packaging protection material such as chips or molded elements made from expanded platsics
  • shredding and disposal of waste from cardboard packaging and corrugated cardboard
  • shredding and disposal of punch grids, in the production of folding boxes
  • compacting and recycling of waste material in container or baling presses.

Dedusting and filter systems

Filter systems are used to clean the extracted air. Depending on the dust characteristics and quantities different filter media (needle felt, textile, fleece) as well as various dedusting systems (reverse air, compressed air, vibration) are applicable.

Collecting and capturing devices

The optimal layout and design of capturing elements are necessary for a secure and energy-saving extraction system. The range of material to be extracted reaches from finest dust particles over gases to endless trimming waste.

Duct systems for conveying dust and material

Captured dust, chips and other process waste is conveyed in a duct system. The type of material (steel, stainless steel, aluminium or plastic) and the thickness are adapted to the material being conveyed. Radial fans provide the necessary negative pressure in order to create the conveying current. They can convey the extracted material directly (transport fans) or be positioned on the clean air side behind the separator systems (clean air fans). Change-over elements, explosion control and other sensors need to be integrated in the design of the duct systems.

Injector systems are used for specialized applications be it for the transportation of edge trim or the conveying of granule and pellets. In order to achieve reliable operation and economical conveying speeds, the right balance between duct dimensions and the fan parameters is essential.

Ventilators and shredders

Radial fans provide the necessary negative pressure which is needed for creating the conveying current. The fans can either convey the aspired material directly (transport fans) or be positioned on the clean air side behind the separator systems (clean air fans). Injector systems are used for specific applications such as conveyance of trim and granules.
However production waste is often generated in sizes that do not permit reliable, economic extracting. Therefore the suctioning process is preceeded by a shredding system (shredding fans, cutters, cutting mills, single and multi-stage macerators, granulators).

Separating devices

Similar to collecting, the selection and design of the separation method also needs to be highly customized to the respective material stream and quantity. Cyclone, gravity, and grid separators in a large range of sizes - often combined with special high-volume rotary feeders - are adapted to each application in a targeted manner.

Electrical control systems

Suction and disposal equipment requires simple robust and clearly structured electrical controls. Reliability, ease of use as well as energy efficiency are essential. Furthermore, intelligent adaptation to performance load/need (e.g. speed control, sensors) is necessary to ensure the facility can be operated economically. These goals are achieved through deliberate project planning, an energy management system as well as customization during commissioning.

Silo and storage systems

In most cases, dust, chips and other process waste are valuable resources and therefore need to be compacted or stored before being processed along in the recovered substance cycle. Various silo systems are available (textile, steel or aluminum silo, container).

Compacting devices

After separation from the conveying air, suctioned dust, chips, or production waste often have to be converted into an easy-to-handle form for the subsequent recycling or disposal process. Depending on the type and amount of waste various hydraulic compacting systems are available: container compactors, baling and briquetting presses. Proper selection and design is essential in order to ensure reliable, clean, efficient and space-saving handling of waste.
