More specifically, embodiments of the present disclosure relate to methods of handling, preparing and producing meat products. Certain embodiments of the present discourse relate to methods and systems for handling and preparing jerky. As used herein, the term “jerky” is not limited to any particular animal product. Jerky includes, but is not limited to, meat product formed from any one or more of bovine, fowl, porcine, caprine, poultry, and aquatic animals.

BACKGROUND

Existing methods of producing jerky products generally comprise marinating or seasoning thawed meat in a batch form where the meat product is loose. The product is marinated or seasoned for a desired amount of time and later transferred to a cooking or drying operation. Existing processes are labor intensive and inefficient.

SUMMARY

Accordingly, there has been a long-felt but unmet need to provide a method and system for handling, preparing and cooking jerky in a more efficient manner. There further exists a need to provide methods and systems that reduce the amount of handling required during jerky preparation, as well as a need to increase the safety of jerky-production operations with respect to both the manufacturers and consumers of the product.

In various embodiments, a method of preparing meat products for consumption is provided. In one embodiment, a method is provided wherein a seasoning, marinade or sauce is provided and placed within a tank, bin or receptacle. A meat product (e.g. turkey, beef, salmon, yak, etc.) is cut, carved or sliced to a desired thickness. In some embodiments, it is contemplated that the meat product is sliced while in a frozen or semi-frozen state. The sliced meat product is then placed onto one or more screens, and the meat product(s) are preferably spaced to minimize contact between adjacent meat product. The one or more screens are provided on a magazine that is operable to receive a plurality of screens. The magazine or frame comprising one or more screens is then transferred to the tank, bin or receptacle comprising the marinade. The magazine comprising screens and meat product is allowed to marinate for a period of time (e.g. 1-12 hours). After the period of time has elapsed, the screens are removed from the tanks and the meat is cooked and/or dried. In preferred embodiments, the racks comprising meat product are inserted into cooking racks or “trucks.” The truck(s) are then moved to a cooking oven, dehydrator or smokehouse. In various embodiments, the meat product is cooked at specific temperature settings for a period of time (e.g. 1-2 hours) and/or until the meat product is provided at a specific temperature (e.g. 160 degrees F.). Once the desired cook time and/or temperature is achieved, the meat product is removed from the oven, smoker, or smokehouse and allowed to cool. After cooling, the meat product is packaged and ready for shipment, sale, consumption, etc.
