Sizing accuracy with an underwater square- opening chain sizer is improved by reducing the rate of travel of the chain and by two passings of the fruit through the sizer. A sizer with hex- agonal-shaped openings gives a better sizing ac- curacy with a single passing of fruit than the! square-link chain with two passings. The hexagonal-opening sizer is recommended for use at rates of travel up to 50 , with an angle of incline no greater than 20 degrees, and with a constant supply of fruit. Three types of hydrofillers were developed and examined, and of these, the accumulator type seems the most suitable for consideration as a pallet-box filler. It is relatively simple in design and operation and, according to tests with a pilot model filler of 1-bushel capacity, should handle the fruit in a relatively gentle manner. Containers loaded underwater have a slack fill upon transfer to air because of fruit bridging and poor nesting while underwater. This problem needs investigation, especially i
