A method for processing carcasses of livestock, includes the processing steps of: positioning a hanging livestock carcass; making an incision along the spine of the positioned hanging livestock carcass; loosening the meat from opposite sides of the feather bones of the spine; and splitting the spine of the carcass. A device for processing carcasses of livestock is arranged for enabling the process steps.

A power operated rotary knife including an annular rotary knife blade supported for rotation in a blade housing. The rotary knife blade including a body and a blade section extending from the body. The body includes an outer wall including an arcuate surface having an upper region extending from a first upper end portion to a second intermediate portion and a lower region extending from the second intermediate portion to a third lower end portion. A plurality of gear teeth extend downwardly from the upper end of the body, each of the plurality of gear teeth including an outer peripheral face forming a portion of the upper region of the arcuate surface of the outer wall. The body outer wall includes a bearing surface having a lower bearing face in the lower region of the arcuate surface and an upper bearing face in the upper region of the arcuate surface.

Disclosed is a method for realizing batch-based traceability for pork based on a QR code. Based on the QR code, user information is added to a web address carried by the QR code to realize the traceability for the pork. The method includes: 1) registering basic information of pigs in breeding and brokering processes; 2) printing an initial traceability QR code of a carcass in a slaughtering process; 3) adding user information to the initial traceability QR code in a selling process, and updating the user information to the traceability system; and 4) scanning the traceability QR code to recall data of the traceability system in a catering process to achieve transparent information. The pork and pork products are traced from production process to the selling process.

A bung driller is provided for cutting free the anal opening and rectum end of an animal carcass by cutting around the anal opening and rectum end. The bung driller includes a longitudinal, drilling tube with an open cutting end, a mandrel centralized inside the drilling tube, and a bung holder located inside of the drilling tube and surrounding the mandrel. Contamination of skin surface and meat surface by fecal matter is a problem when cutting free the anal opening and rectum end of a carcass. The bung holder located inside of the drilling tube provides a holding force to the skin surface around the anal opening and makes a volume wherein fecal matter escaping from the intestine is caught.

Disclosed are embodiments of nanoparticle compositions, methods and systems for disinfecting animals and food products along the whole food provision chain. In one embodiment, a composition includes nonionic metal nanoparticles. The composition may be a spray, an oil, a solution or other appropriate composition for ingestion or application to food products. The silver nanoparticles maintain a stead MIC and do not exhibit microbial resistance as do conventional colloidal silver and silver nanoparticles made by chemical synthesis.

A slaughterhouse processing tool including two opposite knives mounted to a knife holder via respective mounting structures, the knife holder further including an actuator, at least one of the mounting structures being movably mounted to the knife holder, the actuator being coupled to the movably mounted mounting structure for moving the mounting structure relative to the knife holder.

A holding element positions back parts or parts thereof of poultry carcasses having a neck side, a hip side, a body exterior side, and a body interior side, wherein the back part has a spinal column or parts thereof and a rib structure having at least vertebral rib pairs or parts thereof. The back part has a region, on the exterior side of the body relative to the rib structure, that has back-flesh. The holding element includes a holding device with at least one controllable clamping element. The at least one clamping element is configured and adapted to releasably fix the back part at least in some regions on the holding device by non-positive and/or positive locking engagement with the body interior side.

A method for processing food products (12) includes transporting the food products by a first conveyor (11), an X-ray unit (13) positioned between the intake end and the discharge end of the first conveyor to acquire a first set of product-specific data relating to the food product transported. At least one first optical camera (17), assigned to the first conveyor, is used to acquire a second set of product-specific data relating to the food product. A control unit (18) is used to receive and integrate the first and second data sets to analyze the composition of the food product and determine parameters for the food product. Based on the determined parameters of the food product, the food product is cut with a cutting unit, under the control of the control unit.

An apparatus includes a gambrel that defines two hooks configured to support an animal carcass. A fastening system is operatively connected to the gambrel and is configured to releasably connect a bladed tool to the gambrel. In one embodiment, the fastening system includes at least one magnet that retains one or more tools with magnetic force. The apparatus provides a convenient, safe, and clean place to store tools while processing an animal carcass.

A power operated rotary knife including an annular rotary knife blade supported for rotation in a blade housing. The rotary knife blade including a body and a blade section extending from the body. The body includes an outer wall including an arcuate surface having an upper region extending from a first upper end portion to a second intermediate portion and a lower region extending from the second intermediate portion to a third lower end portion. A plurality of gear teeth extend downwardly from the upper end of the body, each of the plurality of gear teeth including an outer peripheral face forming a portion of the upper region of the arcuate surface of the outer wall. The body outer wall includes a bearing surface having a lower bearing face in the lower region of the arcuate surface and an upper bearing face in the upper region of the arcuate surface.
