Quality safety tracing method for food processing enterprises

Abstract

The invention discloses a quality safety tracing method for food processing enterprises. The quality safety tracing method includes the steps that a laser coder generates random tracing codes according to a coding rule when a laser marking machine in a production line device is dynamically read in an on-line tagging mode; the laser marking machine carries out tracing mode marking on products on a production line, and two-dimension codes and plain codes are all marked on packages; a fixed reader is used for scanning and reading designated tagged code portions of the products; the two-dimension codes are successfully scanned and read, the tracing codes are recorded, and relevance between the tracing codes and commodity attribute information is completed; if the two-dimension codes fail to be scanned, the two-dimension codes will be removed through a removing device; the commodity tracing code information and the commodity attribute information are recorded into a relational database; after the products are packaged, package code data and product tracing code data are related; the products are stacked, stacking codes and tagged stacking codes are generated, and the stacking codes and the product package code data are related; the stacking codes are scanned, storage of the products is completed, delivery orders and the stacking codes are scanned to complete delivery, and the database records delivery information.

Description

technical field [0001] The invention relates to an electronic information technology and automatic identification, in particular to a method for tracing the quality and safety of a production line of a food processing enterprise. Background technique [0002] The problem of food safety is a chronic disease that has been around for a long time but is difficult to cure. It has brought serious harm to the health of the eaters, and has also caused huge psychological fear and obstacles to the public, and even formed social panic, destroying social stability and harmony, and promoting food safety. The construction of supervisory informatization is imperative. [0003] At present, my country has carried out food traceability pilot projects in some fields, and established a food traceability information system and network exchange platform, such as "Regulations on Traceability of Entry-Exit Aquatic Products (Trial)", "Guidelines on Traceability of Beef Products", "Beef Quality Trace...

AI Technical Summary

Problems solved by technology

[0005] 1. Food traceability codes are usually circulated using batch codes, and the issue of single products cannot be clarified; at present, the national article coding center for single product traceability codes has not yet defined them, and each enterprise is usually determined by the enterprise according to the type of product, production plant, production line, The sequence traceability code of the completion of the date and other rules, and the code has been generated before production

This will easily lead to coding rules that have been formulated according to certain rules at first, so it is easy to be seen through by counterfeiters and counterfeit in sequence. At the same time, it is also convenient for a certain product to have problems or expired recycling.

[0006] 2. Since the product code is assigned to the next step without reading and verification, it is impossible to know the status of the product code, such as whether the code is assigned successfully, whether it is assigned to the designated area, whether the assigned product code is clear, and it is easy to cause terminal failure. The commodity code cannot be read during the query, which affects the traceability of food quality and safety

[0007] 3. Existing food companies generally use manual sampling to ensure the circulation of qualified products into the next link. This method will greatly reduce production efficiency, increase labor costs, and easily cause missed inspections, and cannot prevent unqualified products. produce

[0008] 4. Some food companies use online reading to ensure the pass rate of code assignment, but due to the limitations of packaging materials, speed, and technology, it may result in a low reading rate of the assigned code, and subsequent information based on reading data Queries and information associations make a big difference

[0009] 5. For commodities with a traceability code only in a single small package, there is a lack of identification and association of the outer box, and only part of the information of the product can be queried through the terminal, but the detailed information of the intermediate process of circulation, such as boxing, warehousing, and distribution, cannot be obtained Information in other links can easily cause management confusion

[0010] 6. A small number of enterprises assign supervision codes to all levels of food packaging, but they have not uniformly and effectively established the correspondence between the codes at all levels, which is not conducive to the subsequent production settings, records, adjustments, etc. related to products in the industrial chain
