Abstract: A fruit or other produce orienting device, particularly suited for orienting apples, orients a piece of fruit with its stem axis horizontal so that it can undergo quality inspections. The device employs a cylindrical drive roller which engages the fruit on one side, and causes it to rotate, and a pair of freely rotating orienting rollers which engage the fruit across from the drive roller, and cause the fruit to achieve the desired orientation as it rotates. The first orienting roller is cone shaped with a tapered flat or concave surface so that it will steer the fruit toward the second, opposing roller, which has a thin disk shaped portion with a front surface that engages the fruit. The front surface of the disk shaped portion tends to align itself with the flat edge of the fruit at its stem or calyx end, and this causes the rotating fruit to be oriented quickly with its stem axis parallel to the roller axes, and then maintains the fruit in the correct orientation once it is achieved.

Abstract: A modified milking machine claw having ferrules or connectors with an aperture in the surface of each ferrule to allow complete sanitation of milk lines and removal of debris from pockets between the ferrule and the tube lumen of short milk tubes.

Abstract: A low-energy-consuming apparatus and method for controlling vacuum levels in machine milking and other vacuum systems subject to air leakage utilizes in combination a high vacuum reserve, a low-vacuum end (pipelines), a dual vacuum controller positioned between the high-vacuum reserve and the low-vacuum end and an adjustable speed drive (ASD) motor on a vacuum pump to regulate the delivered air to match the air usage in the low-vacuum end. The dual vacuum controller senses vacuum disturbances in the low-vacuum end and adjusts the flow rate of air from the low-vacuum end to the high-vacuum reserve rather than using external air makeup, thus providing a controlled vacuum with minimum pressure variance and energy input. Energy savings and demand reduction of about 50 percent (50%) during milking are realized under the new system.
