A grading and rejecting device and grading method in the process of water-free keeping alive transportation

Abstract

The present invention relates to a grading and rejecting device and a grading method in the process of anhydrous keeping alive transportation. The device includes: a scanning device, a rejecting device, a fish storage tank and an analysis controller; The analysis controller is connected; the scanning device is used to scan the fish image in the fish storage tank and transmit the fish image to the analysis controller; the analysis controller is used to determine according to the fish image The shelf life of the fish and control the rejecting device according to the shelf life; the rejecting device is used to remove the fish in the fish storage tank. The device and method provided by the invention can realize graded transportation according to the shelf life of fish.

Description

technical field [0001] The invention relates to the technical field of preservation transportation, in particular to a classification and rejection device and a classification method in the process of waterless preservation transportation. Background technique [0002] As the most economical transportation mode at present, preservation transportation can effectively guarantee the quality of consumers when eating aquatic products, and effectively save costs. Therefore, the future transportation method will develop in the direction of anhydrous transportation, but The current anhydrous preservation transportation system is not complete, and there is no complete device and effective method to judge the state of fish during anhydrous preservation transportation to predict the shelf life. Judging in the current anhydrous preservation transportation process Whether the fish is dead or not is judged by observing the gill movement of the fish in the package at regular intervals. Thi...

[0002] As the most economical transportation mode at present, preservation transportation can effectively guarantee the quality of consumers when eating aquatic products, and effectively save costs. Therefore, the future transportation method will develop in the direction of anhydrous transportation, but The current anhydrous preservation transportation system is not complete, and there is no complete device and effective method to judge the state of fish during anhydrous preservation transportation to predict the shelf life. Judging in the current anhydrous preservation transportation process Whether the fish is dead or not is judged by observing the gill movement of the fish in the package at regular intervals. This method cannot accurately judge the death time of the fish and predict the quality of the transportation terminal, so it cannot be transported according to environmental parameters and post-death conditions. Time to judge the quality of the transport terminal

[0003] In addition, in the current transportation process, the activity of the product before transportation cannot be evaluated, and there is no effective method to effectively grade according to length, width, height, weight, and surface bleeding. Aquatic products are directly transported without grading and classification. This mode of transport cannot guarantee the survival rate of fish during the anhydrous preservation process, and it is impossible to judge the condition of the transport terminal when the death time of the fish cannot be determined.

In the current market, there is currently no effective method to analyze and evaluate the liveness of fish at the front end of transportation; to analyze the dead and alive state of fish in a dormant state during transportation to accurately determine the time of death of fish, and to analyze the liveness of fish during transportation. The terminal predicts the quality of the fish after death and properly regulates the current environment according to the prediction results
