Adding an additive to a meat product
Method of treating a large number of meat products, in particular slaughtered poultry or parts thereof, in which an additive is added to the meat products. The additives products are supplied to meat products using a conveyor which is designed to feed the meat products sequentially in groups or separately. Each meat product or each group of meat products are subjected to an additive-adding treatment which is adapted to the corresponding product or to the corresponding group of meant products.
1. A device for applying multiple coatings of different marinades in overlapping layers onto meat products comprising:
a. a conveyor device comprising a track and a plurality of meat product holders adapted to hold meat products wherein the meat product holders are displaceable along the track to convey meat products and wherein each meat product holder comprises a rotary member adapted to rotate the meat product about a vertical axis;
b. a plurality of marinade application stations positioned one behind another along the track of the conveyor device, so that the meat products sequentially pass along the marinade application stations;
c. at least one of the marinade application stations adapted to apply a different marinade than the other marinade application stations;
d. at least one of the marinade application stations comprising at least one nozzle for emitting at least one jet of at least one marinade;
wherein the marinade application stations are adapted to apply marinade onto a meat product conveyed by the conveyor device and rotated about the vertical axis by the meat product holder to uniformly coat the outer surface of the meat product with overlapping layers of different marinades.
2. The device of claim 1 , wherein at least one marinade application station is adapted to coat only selected portions of the outer surface of the meat product with the at least one marinade and wherein the device further comprises shielding means to substantially shield non-selected portions of the outer surface of the meat product from the at least one marinade.
3. The device of claim 1 , further comprising analyzing means to analyze the meat product after marinade coating and obtain a result, wherein the device is adapted to coat the meat product with additional marinade if the result is unsatisfactory.
4. The device of claim 3 , wherein the analyzing means comprises a camera.
5. The device of claim 1 , wherein the at least one marinade application station comprises means for generating a gas flow, the marinade including small particles entrained in the gas flow.
6. A device for applying multiple coatings of different marinades in overlapping layers onto meat products, the device comprising:
a. a conveyor device comprising a track and a plurality of meat product holders, each meat product holder adapted to hold one or more meat products suspended downwardly from the meat product holder, wherein each meat product holder is displaceable along the track to convey meat products, and wherein each meat product holder comprises a rotary member adapted to rotate the meat product about a vertical axis;
b. a plurality of marinade application stations positioned one behind another along the track of the conveyor device, so that the meat products sequentially pass along the marinade application stations;
c. at least one of the marinade application stations being associated with a different marinade than the other marinade application stations, wherein the marinade application stations are adapted to apply different marinades successively to the outer surface of the meat product; and
d. at least one of the marinade application stations comprising at least one nozzle for emitting at least one jet of at least one marinade;
wherein the marinade application stations are adapted to apply marinade onto a meat product conveyed by the conveyor device and rotated about the vertical axis by the meat product holder to uniformly coat the outer surface of the meat product with overlapping layers of different marinades.
7. A device according to claim 6 , wherein the at least one marinade application station includes means for generating a gas flow, the marinade including small particles entrained in the gas flow.
