Abstract: Apparatus for peeling shrimp including powered roller assemblies each made up of a peeling roller and a drive member attached by a releasable connection. Roller connection structure at a first end of each roller assembly mates with reciprocal drive connection structure in the drive member. An adjustable element extending through the drive member allows the connection to be released and the roller assembly separated into a roller segment and a drive member segment. In other versions the roller segment can be composed of a series of segments having the same or different peeling surface characteristics in which the individual roller segments are similarly releasably connected.

Abstract: An improved drive system for a shrimp peeling apparatus includes a support frame with a first and a second plurality of rollers mounted thereon. One of the plurality of rollers have rollers that are of a larger diameter than the other rollers. The drive mechanism includes a computer controlled motor that engages a cylindrically-shaped shaft of each roller and a drive mechanism that engages the cylindrically-shaped end portion. The motor drive can be a computer controlled vector motor that can vary the rotational angular movement of each roller during each stroke. This enables variations in angular rotation and rotational speed depending upon the type and grade of shrimp. This configuration also enables each roller to constantly "advance" by changing the degree of angular rotation of each roller at each stroke, gradually presenting a different wear surface to the shrimp and prolonging roller life.

Abstract: A shrimp peeling apparatus includes a support frame upon which are mounted a plurality of larger diameter rollers and a plurality of smaller diameter insert rollers. Each smaller diameter insert roller is supported by two adjacent larger diameter rollers and is held in contact to the adjacent larger diameter rollers with a hold down assembly. The assembly includes a tension member and an adjustment for varying the load transfer between a selected smaller diameter insert roller and the pair of larger diameter rollers.

Abstract: A shrimp peeling apparatus provides an improved geometry that increases efficiency and yield. The apparatus has particular utility when used to peel Pendulous Borealis variety shrimp. The apparatus includes a support frame that supports a first plurality of rollers wherein the central longitudinal axis of each of the rollers of the first plurality lies in a common inclined plane. A second plurality of insert rollers is supported by the first plurality of rollers, wherein the diameter of each of the first plurality of rollers is much greater than the diameter of each of the second plurality of insert rollers. An improved geometry governs the respective positions of the smaller diameter insert rollers relative to the common plane of the larger diameter rollers.
