The system is composed of a dehydration tank with a horizontal mixing shaft. Three loading inlets located on the top of the tank allow an easy loading of the Egg Waste following the flow generated by the harvesters. The loading is controlled by the system automatism which does or doesn’t authorize the filling operation, depending on the type of loading cycle selected at the beginning of the harvesting campaign.

The product level in the dehydrator is controlled by a level sensor based on radar technology and eventually by calculation of the quantity of Egg Waste transferred to the dehydrator by using a flow meter or impulses given by the harvesters or by the transfer station.

During the dehydration phase, the process is completely automatic. The mixing shaft continuously blends the product. Fresh air enters the dehydration tank above the waste through a valve and a heat exchanger. Fresh air, vapors and gases emitted from the warmer product are sucked through a ductwork system by a turbo fan into the thermal oxidation chamber where they are burned, then no contaminated air residues will be released into atmosphere. The hot air produced by the burner in the oxidation chamber, if necessary, is lightly cooled by fresh air before it is circulated through the double jacket around the dehydration tank, then up through the heat exchanger, and finally through the exhaust fan and chimney.

The process creates a slight depression/ negative pressure in the dehydration tank.
After a request by the operator on the control process and in some conditions, the visit trap-doors located on the top of the unit may be opened for a short period to see the inside of the dehydration tank during the treatment.

When a timer reached the preset dehydration cycle duration, corresponding to a level of preset treatment, the heat production provided by the burner is stopped automatically (the operator can also manually stop the heating process). The circulation of fresh air allows the progressive cooling of the unit as well as of the treated product. When the cycle is complete, the system stops automatically.
To discharge the treated product, the operator opens the discharging door located on a side of the dehydration tank, installs the safety guard to protect the personnel, and activates the startup of the unloading cycle. At this stage, the mixing shaft is set into reverse rotation, which forces the treated product through the discharging door.As a result, there is no special cleaning of the tank before proceeding to a new loading cycle.
