Adding an additive to a meat product
Method for 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 meat products are supplied to additive-adding means using a conveyor means, the conveyor means being designed to feed the meat products sequentially in groups or separately. The additive-adding means subject each meat product or each group of meat products to an additive-adding treatment which is adapted to the corresponding meat product or to the corresponding group of meat products.
1. A method for conveyance of a plurality of meat products and the selective application of an additive onto one or more selected meat products, the method comprising:
a. conveying a plurality of meat products with a first conveyor device having a first conveyor track and a plurality of meat product holders movable along said first conveyor track, each meat product being held by a meat product holder of the first conveyor device;
b. selecting from said plurality of meat products conveyed by the first conveyor device at least one meat product that is to be subjected to an additive-adding treatment;
c. transferring at a transfer point along the first conveyor track the at least one selected meat product from the first conveyor device to a second conveyor device while other of the plurality of meat products are conveyed by the first conveyor device past the transfer point, said second conveyor device having a second conveyor track and a plurality of meat product holders movable along said second conveyor track, wherein the at least one selected meat product is transferred from a meat product holder of the first conveyor device to a meat product holder of the second conveyor device;
d. subjecting the at least one selected meat product to at least one additive-adding treatment by at least one additive-adding device positioned along the second conveyor track, said at least one additive-adding device treating the at least one selected meat product with an additive while the at least one selected meat product is held by the meat product holder of the second conveyor device; and
e. conveying the at least one selected meat product back to the transfer point and transferring said at least one selected meat product back to a meat product holder of said first conveyor device.
2. The method of claim 1 , wherein at least some of the plurality of meat products are entire chickens or parts thereof.
3. The method of claim 2 , wherein at least some of the plurality of meat products are chicken legs.
4. The method of claim 1 , wherein the method further comprises detecting at least one parameter of the plurality of meat products with a detector positioned along the first conveyor track upstream of the transfer point.
5. The method of claim 4 , wherein the detector is a camera.
6. The method of claim 1 , wherein the at least one additive-adding device comprises a nozzle and wherein subjecting the at least one selected meat product to at least one additive-adding treatment comprises using the nozzle to direct one or more jets of a liquid additive at the at least one selected meat product in order to apply additive onto an outer surface of the at least one selected meat product while the at least one selected meat product is held by the meat product holder of the second conveyer device.
7. The method of claim 1 , wherein subjecting the at least one selected meat product to at least one additive-adding treatment comprises electrostatically applying one or more additives onto an outer surface of the at least one selected meat product while the at least one selected meat product is held by the meat product holder of the second conveyer device.
8. The method of claim 1 , wherein the additive comprises a liquid, wherein the at least one additive-adding device comprises at least one jet nozzle, and wherein subjecting the at least one selected meat product to at least one additive-adding treatment comprising using the at least one jet nozzle to impinge the additive onto the at least one selected meat product so as to penetrate into the at least one selected meat product while the at least one selected meat product is held by the product holder of the second conveyer device.
9. The method of claim 1 , wherein the at least one additive-adding device comprises at least one injection needle and wherein subjecting the at least one selected meat product to at least one additive-adding treatment comprising injecting the additive into the at least one selected meat product with the at least one injection needle while the at least one selected meat product is held by the product holder of the second conveyer device.
