Vacuum conveying of animal offal
Vacuum conveying of:
- Residue from filleting lines.
- Waste from slaughter lines.
- From the blood catchment to the silo.
- Manure and paunch manure.
- Parts of the hide and head of calves and cattle.
- Bone parts.
- Organ parts.
Generally a poultry filleting company or slaughterhouse has one or more filleting and/or slaughter lines built by Stork , Systemate Numafa or Meyn Oostzaan for example. At the start of the line the slaughtered product, the breastcap, is stuck on a holder, a sort of chain belt. The product is then transported through several of the machine’s stations, also called modules. A process of dividing up the breastcap takes place at each point and produces more waste: skin, bones with waste meat and lastly the carcass. This waste goes into a pipe via the three separate hoppers which each have their own shut-off system. These three pipes are connected to each other and come out into a cyclone where air is separated from the product. There is a automatic operated bottom under the cyclone which allows the product to fall into a plastic bin. The whole cycle of removal by suction at each point, discharge, pump control and cleaning is regulated by the software in the central PLC of the transport system.
Systematic Vacuum vacuum transport
Systematic Vacuum offers a complete solution for the quick, safe and proper transportation of offal by vacuum. This is necessary because approx. 50 products per minute enter each hopper. The valve under the hopper is opened after a specific period depending on its volume. The other hoppers on the same line are then blocked. The product is sucked out of the hopper at high speed and transported through the central pipeline to the cyclone where it is collected. The valve closes again and the next valve on the line is opened. This cycle is repeated several times until the cyclone is filled with product and then the system is deaerated. The vacuum pump is closed. The flap under the cyclone opens and the product falls into plastic bins.
The vacuum pumps keep the system under pressure and ensures the required transport speed. The system must of course be cleaned at the end of the day. This has also been automated. A cold flushing system rinses the hoppers and pipelines first, after which they are cleaned with a soapy solution from a heated tank (CIP ). This process is repeated several times and then cold water is used for final rinse and emptied and plugged.

High quality technology
Systematic Vacuum offers a complete turnkey solution for these applications consisting of: collection hoppers, valves, transport pipework, cyclone units, vacuum pumps, control, process software and cleaning systems.
Hoppers, pipework, valves and cyclone unit are made entirely from stainless steel and therefore maintenance-free. Several versions are available, depending on the local situation.
The pump system is designed to achieve a deep vacuum, high transport speeds, long lifespan, low energy costs and low maintenance costs. It has been constructed using the most modern pump technology, specially selected for this application.
The control we have developed regulates the process accurately, monitors, controls and corrects the process.
Leading poultry processing companies, calf slaughterhouses, hide processors and pig slaughterhouses in The Netherlands and Belgium have used this system for many years. Ask our customers about their experiences.
