Abstract: A device for massaging a portion of meat, which device comprises a frame and a vessel supported in that frame and driven rotatably on a lying axis, said vessel has a longitudinal wall and two end walls, wherein agitation members are arranged in the vessel, wherein the inner side of the longitudinal wall of the vessel is provided with agitation members standing thereon, wherein the agitation members are formed by hollow bodies, the closing edge of which is situated outside the vessel, so providing an easy discharge and cleaning of the vessel, whereas the agitating members can be easily constructed.

Abstract: In a device for pumping meat-containing products, such as pieces of meat, meat paste and meat pulp (dough), it is aimed at avoiding problems of the meat forming bridges in a feed space, of meat remaining in the device during a too long time, of too much churning up of the meat and to provide a simple device adapted to discharge at will a continuous meat discharge flow under constant pressure or at a constant flow rate. Thereto, there is a feed space with means for feeding the meat under pressure to one of a number of cylinders with reciprocating pistons or the like, acting in parallel, with a controlled valve in the delivery line between each piston and a common discharge duct. Several feed means are proposed, depending on the application of the devices for pieces of meat on the one hand or for paste or pulp.

Abstract: For measuring the fat content of meat it is known to determine the specific gravity of the meat, which at a given temperature and for a given type of meat is a measure for the fat content. This invention provides a novel way to realize this easily and rapidly in the factory, e.g. in a production line. Thereto, meat portions are weighed and compressed in a closed space, of which the volume in compressed condition of the meat is determined, so that the ratio of weight and volume gives the specific gravity. The weighing device is mounted to the side of an upstanding cylinder press with its top at the level of the weighing surface or of an immediately adjacent table surface, an easily movable cover to open and close the cylinder and a bottom being a press platen piston movable up and down to compress the meat with closed cover and to move it further upwards to above the cylinder with open cover.
