Patent number: 6129625Abstract: A method of trimming cuts of meat by imposing on an electronic controller the trim parameters for a meat portion. The meat portion is then scanned with an electronic ultrasonic sensor to locate and identify the natural physical makeup of the meat portion. After determining the natural conditions that exist in the meat portion, the sensor transmits signals to the controller to advise the controller of the nature and location of the sensed condition. That data is compared to the trim parameters imposed on the controller which then determines the trim requirements for that meat portion in that sensed condition. The controller then controls a meat trimming mechanism to trim the meat portion consistent with the parameters of the foregoing evaluation.Type: GrantFiled: August 26, 1999Date of Patent: October 10, 2000Assignee: Townsend Engineering CompanyInventors: Stephen H.

Patent number: 5989609Abstract: The sausage strand is extruded onto a belt and carried through a brine shower system for about 40 seconds. The brine is sprayed through nozzles onto the sausage while traveling on the belt. The sausage is turned several times during the shower to insure even brine distribution. The conveyor speed is controlled to match the speed of the extruder thereby preventing stretching of the product as it is being extruded. The conveyor provides exact motion control of the sausage rope and the dwell time in the brine shower can be exactly regulated. Since the conveyor system is open it lends itself to easy cleaning and visual inspection. The conveyor consists of a frame which supports the conveyor system, the brine shower system, air knives and the infrared heater. The brine shower system is composed of a drip pan, a brine tank, a centrifugal pump and a plumbing/brine distribution network. The centrifugal pump conveys the brine from the tank through the brine distribution network.Type: GrantFiled: September 10, 1998Date of Patent: November 23, 1999Assignee: Townsend Engineering CompanyInventors: Jos Kobussen, Mart Kobussen, Jaap Kobussen

Patent number: 5971842Abstract: A meat encasing machine has a looper horn, linking chain and conveyor which, prior to production, have home positions which are determined. A pulsed signal is generated as the looper horn rotates and is transmitted to an amplifier from an encoder on the servo motor for the looper horn and the conveyor. The output pulse signal is then reduced in frequency so that it can be read by a PLC. The PLC counts the pulses in the signal and can determine the relative position of the looper horn based on the count and can therefore minimize the rotation of the looper horn in the home position at the beginning of each new cycle. The meat encasing machine may also be controlled such that the linking chain, looper, and conveyor have no direct mechanical or electrical interaction between each other. By driving the components with separate servo motors, each can be precisely controlled in the desired ratios with respect to each other.Type: GrantFiled: January 8, 1998Date of Patent: October 26, 1999Assignee: Townsend Engineering CompanyInventors: Michael S.
