VALLI offers three systems that can be combined together according to the equipment in use and all are fully programmable. The VALLI FEED HOPPER is used with equipment for PULLETS, LAYING HENS and BREEDERS. This patented system is unique and comprises independent hoppers, which run on the rounded, outer side of the troughs.
The system can be programmed to choose both the number of runs and the waiting period at the end of the forward run. The hoppers have been carefully designed to avoid the feed being compressed or upset the mix of the feed. VALLI also offers the “BIP BIP” series, a simple but efficient accessory that removes any left-over feed from parked elements.
In the equipment for pullets it is also possible to fill only those hoppers required as regards number and position and to leave empty the hoppers that are not required to observe the weaning plan. On the other hand, the FLAT CHAIN system can be used for all the equipment – PULLETS, LAYING HENS and BREEDERS. One multi-hopper tower for the feed for each row of cages is standard; two multi-hopper towers may be set up to divide the chain into two circuits and reduce the run time and feed selection.
Finally, we have a SPIRAL feed system used to supply the feed dishes in the equipment for BROILERS and used as an additional feeding system for distribution onto the litter in the LAYING HENS ENRICHED Space Colony. Silos up to 50 cubic metres are available for all the feeding systems, either alone or in tandem, with screw conveyors supplying up to 4500 kg per hour, depending on needs.
2. Egg Collection
In all the equipment for LAYING HENS and BREEDERS, the eggs roll down a floating floor in wire mesh with a slope of 6.5 – 7 degrees to the egg channels. The self-cleaning egg belt supports are supplied as standard, while there is an optional cleaning system that will deliver a jet of air that is channeled over the eggs. In addition to the baffle for egg protection, it is also possible to install a baffle wire and the egg-stop wire. There are two systems designed for egg collection:
The LIFT SYSTEM
Is simple and ensures the cleanliness of the eggs thanks to a single transfer: from the conveyor belts directly to the rod conveyor. This rod conveyor is lifted and accurately positioned on the collection tier. An optional variable-frequency drive enables you to change the speed of the belts.
The ESCALATOR-ELEVATOR SYSTEM.
This comprises a series of mini CONVEYORS that carry the eggs to the rod baskets of the elevators and separate those with a soft shell and synchronize their transfer onto the carriers. The level of the conveyors can be pre-set according to the Client’s needs. It is also possible to perform a collection on tables positioned directly on the elevators. The egg transporters are available in varying widths according to required flow rates. Covers are provided for outside transport sections.
3. Removal of Manure
All VALLI state-of-the-art equipment is designed to remove manure by conveyor belt. Each tier of the colonies or cages has a 1 mm thick polypropylene belt for the Pullet, Laying hens and Breeders equipment, while that of the Broilers is 1.2 mm thick. The belt is supported by concave profile lateral crossbars. A geared motor for each tier and belt is connected directly to the driving roller with no transmission chain present.
From the conveyor belts of the equipment the manure is carried outside by means of PVC and rubber horizontal, tilted conveyors for all runs; these may be used even in extreme climatic conditions. All models of equipment for Pullets, Laying and Breeders are also available in a version with PVC drying pipes situated on each tier, in the centre of the equipment, for drying of the manure while on the belts. One or more centrifugal fans channel the air to the PVC pipes and then onto all the belts under the cages or colonies. The air can be taken in from inside or outside the shed or mixed, thanks to a system of staggered shutters.
