Meanwhile, the control system controls the front manipulator and the rear manipulator in the front section 61 and the rear section 64, and the conveyor belts 66 of the front section 61, the sterilizing bin 62, the drying bin 63 and the rear section 64. The whole inner bag sterilizing equipment 60 can realize automatic conveying, sterilizing, drying and stacking in the whole process. Thereby avoiding viral transmission and infection.

Based on the same inventive concept, the present disclosure provides a cold chain food sterilization system, which sequentially comprises the following blocks: a separate overwrap sterilization passage 20; a customs cold storage 10 for a procurement area; the whole-support cargo packaging and disinfecting channel 40 is used for the local customs refrigeration house delivery link; a cold chain vehicle disinfection tunnel 50 for the transport link; such as the inner bag sterilization device 60 described above, for use with a merchant freezer. As shown in fig. 1, the independent exterior package sterilization passage 20 is applied to the procurement place customs cooling storage 10, and goods in the procurement place customs cooling storage 10 are sterilized, dried, and automatically stacked through the independent exterior package sterilization passage 20. The inner bags 80 are formed after stacking, and the inner bags 80 are transported to the local customs cooling storage 30 by airplane or ship. When the inner packaging bag 80 in the local customs cold storage 30 is taken out, the inner packaging bag 80 is sterilized and dried through the whole-support goods packaging sterilizing channel 40. The cold chain car is then transported in the sterilized and dried inner bag 80 and sterilized through the cold chain car sterilization passage 50. The cold chain vehicle transports the inner bags in the inner bags 80 to a merchant refrigerator (i.e., the inner bag sterilizing device 60), and the inner bags are sterilized and dried by the inner bag sterilizing device 60.

As shown in fig. 7 and 8, after each block is sterilized, a block professional blockchain sterilization certification is generated immediately, including a procurement customs sterilization certification 212, a whole-pallet package sterilization certification 441, a cold-chain vehicle sterilization certification 51, and an inner food bag sterilization certification 641. In particular, the blockchain sterilization certification may be a paper sterilization certificate. The certificate of sterilization is placed in each subsequent section 64 on the stacked inner pouches 80 by gluing or sewing. Alternatively, the blockchain sterilization certificate may be laser printed onto the stacked inner pouches 80 in each subsequent section 64. Optionally, the blockchain disinfection certificate can also be an electronic seal, and is uploaded to a blockchain network from a traceability device through a network (internet of things) for real-time storage, and the blockchain disinfection certificate cannot be tampered and is permanently traceable. In addition, the disinfection certificate is provided with an identification code, and the stored data of the block chain network and the block disinfection certificate can be traced back at any time through the identification code.

From the above, both the inner bag sterilizing equipment 60 and the cold chain food sterilizing system are based on the block chain technology, and adopt the innovation of food safety management by chain control, and take the side chains of the urban food safety tracing chain, the cold chain and the like as the secondary business chains; the method comprises the following steps of taking a market supervision and management department as a supervision node, taking an agricultural rural management department, an import and export inspection and quarantine management department and a health supervision and management department as supervision nodes, and taking each direct administration city, provincial meeting city, planned single-row city and other city-level food safety management departments as a first-level management chain of the management nodes; the food safety block chain alliance management platform is used as a core, and a chain crossing technology of block chains is applied, so that the food safety of one door, full coverage and traceability is really realized. Meanwhile, in the management process of a city secondary chain, a novel city intelligent central kitchen cluster is used as an important hub, a block chain technology is used for establishing key control nodes from food raw materials to terminals such as food sale operators, catering service operators, unit canteens and the like, food safety hidden dangers are prevented, eliminated or reduced to an acceptable level, key node information of a food safety system is monitored, whole-process controllability, clear authority and responsibility, permanent traceability and encrypted data sharing are achieved, main responsibility of food production operators and key responsible persons is realized, the construction of various standards in the food safety system is promoted, and the food safety of people is guaranteed.

As shown in fig. 8, the cold chain food sterilization system further includes a management chain and a secondary service chain, wherein the primary management chain is an imported cold chain food epidemic prevention alliance chain, the secondary service chain includes a market supervision a department, a market supervision B department, a market supervision C department and a market supervision N department, and the sterilization information is stored in each block in an encrypted manner through the secondary service chain, so that the sterilization information is not falsifiable and is permanently traceable; and the coalition members of the primary management chain share data according to the decryption level, and capture and analyze the information of the link points of the secondary service chain, so that the management of the block chain is realized. Thereby creating a safe and credible import cold chain food epidemic prevention block information management system.

The cold chain food disinfection system can control key points of preventive disinfection of the external package of imported cold chain food, strengthen source management and control, reduce import food input risk, improve port clearance efficiency and avoid cargo overstock port stagnation; the industrial chain and the supply chain are ensured to be stable; repeated disinfection is avoided, and waste is reduced; the market circulation is accelerated; the professional disinfection operation is safe and reliable, and the whole process can be traced.
