Embodiment Construction

[0015] figure 1 Anatomical diagram showing a peeled, or shelled and headed shrimp. A complete shrimp meat 10 includes 6 main segments S1-S6 and tail segments T. The rostral segment S1 has the largest girth of all body segments; the telomere T is sometimes removed along with the shell during processing. Segments S1-S6 are commonly referred to as "somites". As with other features, boundaries B between adjacent segments are often discernible, as indentation I along the dorsum and depression J along the abdomen at the junction of adjacent segments.

[0016] One method of determining peel quality is by counting the number of contiguous segments of peeled shrimp exiting the peeler and classifying each peeled shrimp as high quality, medium quality, or low quality. For example, each shrimp with 6 complete somites S1-S6 (with or without all telsons) can be classified as high quality ( Figure 2A ); not high quality shrimp with complete somites S1-S5 plus more than half of telson S6...

Abstract

Methods and systems using a vision system to process shrimp. The vision system captures images of samples of shrimps. The processor produces a digital image of the shrimps in the samples. Shrimps exiting a peeler are imaged to determine the number of tail segments in each. The shrimps are classified by the number of intact segments, and quality, yield, and throughput computed from the classification results. The processor can control operational settings of the peeler based on the classification results. In a larger system including other shrimp-processing equipment besides the peeler, other points along the processing path can be imaged by camera or sensed by other sensors to determine processing quality and to make automatic operational adjustments to the equipment.

Description

technical field [0001] The present invention relates to an apparatus and method for processing shrimp. Background technique [0002] Shrimp peeling machines, originally introduced due to the high labor cost of manually peeling small shrimps, are now widely used in the shrimp processing industry. Roller shrimp peeling machines are especially dominant in the high-volume peeling industry. US Patent Nos. 2,778,055 and 2,537,355, both to Femand S., James M., and Emile M. Lapeyre, describe the basic structure and principle of operation of a roller shrimp peeler. [0003] Many factors affect the throughput, quality and yield of peeled shrimp. Some of the factors pertaining to the shrimp itself include the type, size, uniformity and freshness of the shrimp. Factors related to peeling equipment include the rate at which shrimp are fed into the peeler, the water flow to the peeler, and finger frame pressure. Other factors relate to other shrimp processing equipment such as washers...
