Dry manure offers a lot of advantages. It can be easily stored, the ammonia emission is reduced, the weight is reduced substantially so transport costs are lower and the manure is more valuable as a fertilizer.
The VDL PoulDry drying tunnel is designed to dry poultry manure, but is also perfectly suitable for drying other substances like digestate, potato wedges or woodchips. The PoulDry consists of 2, 4 or 6 tiers. Its industrial quality is shown by the powder coated perforated steel plates, connected to an industrial transport chain. The chain is driven by motors with a planetary gear transmission.
The product is evenly spread on the top layer with a switching distribution belt. When the product reaches the far end of the tunnel, the plates tilt and the product is automatically dropped on the underlying level. The product then moves in opposite direction and is dried further. The air from the poultry house, or heated outside air, is forced by high pressure fans through the perforated plates (35% perforated).
After the product is transported over the lowest level, the dried product is removed from the tunnel with a screw conveyor. A scraper system under the tunnel removes the dust accumulated on the floor. These fine particles are removed, together with the dried product.
When the tunnel is put into operation the required data will be entered in the controller, after which the tunnel will operate automatically. The software is designed to operate the tunnel in any house or formation. The control panel includes an IXON so the panel can be connected to the internet. This industrial router allows a safe remote login to the control panel, resulting in more user-friendliness and faster and better service.
The unique design of the rail system reduces the friction, as the manure cannot accumulate on the rails. This allows tunnel lengths up to 40 meter.
The planetary gear transmission is directly connected to the shaft and pulls the perforated drying plates connected to the industrial chain. The direct drive in combination with the forced tilting prevent breakdowns and guarantee a long lifespan.
It starts with detailed design until completion on project location. Design always taking into account customer requirements, local circumstances and climatic conditions to meet the best possible scope of supply. To give you an impression of the realized projects, you will find an overview here.
