The present disclosure provides a combined refrigeration and heating device for food industry and a use method thereof. The combined device comprises a refrigeration device and a heating device connected through a waste heat recovery and utilization system. The heating device includes a heating cavity and a heating plate. A first conveyor belt is disposed in the heating cavity. A left end and a right end of the heating cavity are provided with a slanting cavity, respectively. The slanting cavity disposed at the right end of the heating device is provided with a second conveyor belt. A left end of the refrigeration device is provided with a slanting cavity. More than two blocking devices are disposed in the slanting cavity disposed at the left end and the right end of the heating device and the slanting cavity disposed at the left end of the refrigeration device.

A container includes a metal end applied and sealed to an all-thermoplastic container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a chuck wall that extends down from the curl. One or both of the inner surface of the container side wall and the outer surface of the chuck wall has/have a heat-sealable material thereon. The metal end is crimp-seamed or double-seamed to the container body and the heat-sealable material(s) are heated to soften or melt such that the interface between the chuck wall and the side wall is fused. The interface is oriented along a direction relative to internal pressure exerted on the metal end such that stress on the interface caused by the internal pressure is predominantly shear stress.

A process for preparing a stable and homogenous fruit preparation, includes the steps of: (i) preparing a fruit mixture by mixing fruit pieces, optionally in the presence of a fruit matrix, with sugar in an amount included between 10% and 60% by weight relative to the total weight of the fruit preparation, (ii) treating the fruit mixture obtained in step (i) at a temperature ranging between 40 C. and 90 C., and at a pressure from 50 mbar to 1000 mbar, during 15 to 90 minutes, so as to obtain a concentrated fruit preparation having a Brix degree at 20 C. ranging between 50 and 75,
(iii) optionally submitting the concentrated fruit preparation to a heat treatment, at a temperature ranging between 90 C. and 120 C.,
(iv) cooling the concentrated fruit preparation obtained in step (ii) or, when step (iii) is performed, cooling the concentrated fruit preparation obtained in step (iii), to storage temperature.

The present invention relates to a process for preserving vegetables in bulk packs and repacking into smaller packs wherein the same media is used in repacking on as is basis.

A digital pressure canner and related methods of operation that provide for improved safety and consistency during a food canning process by reducing temperature over and undershoot. The digital pressure canner includes a digital control operating with inputs from digital sensors to accurately control the canning temperature during the canning process. By reducing over and undershoot of canning temperatures, foods within the pressure canner are maintained at temperatures sufficient to kill any bacteria or microorganisms for the entire canning cycle. In order to verify operation of the digital canner at sufficient canning temperatures, mechanical safety devices, for example, a pressure relief valve can be utilized in conjunction with digital controllers and sensors to provide audible and visual feedback to a user during the canning process.

The present invention provides a freshness preservation method and a freshness preservation bag that enables to keep freshness of a vegetable, fruit or fresh flower for a long period. A storage bag 10 is formed by a nonporous film 1. Non-adhesive portions are continuously formed on a heat sealed portion 11 of the storage bag 10. The non-adhesive portions function as the vent holes 2 communicating with the outside of the storage bag 10. The carbon dioxide generated from the vegetable, fruit or fresh flower in the storage bag 10 is discharged from the vent holes 2. The oxygen of the outside is shut off by the vent holes 2. The vegetable, fruit or fresh flower is allowed to breath only by the oxygen sealed in the storage bag 10. An oxygen concentration is gradually reduced according to a degree of breathing of each of the vegetable, fruit or fresh flower.

There is provided a method of cooking and sterilization of food arranged in a sealed package comprising a one-way valve that opens at a supra-atmospheric pressure of 20-200 mbar, said method comprising the steps of: a) heating the sealed package to cook the food; b) subjecting the sealed package from step a) to a sub-atmospheric pressure such that gas leaves the sealed package through the valve; and c) autoclaving the sealed package from step b) at a supra-atmospheric pressure.

This invention proposes a method for prolonging the shelf life of perishable fruits and vegetables using a combination of non-destructive thermal and non-thermal sterilization techniques. Leveraging AI-based algorithms, it utilizes traceable data from the entire value and supply chain. This integration allows growers, processors, and traders to collect and analyze traceable data for informed decisions on product quality and safety, effectively minimizing spoilage and quality loss. The environmentally-friendly method uses AI for precise sterilization process control and monitoring, considering factors such as product characteristics and traceability data. This comprehensive approach enhances preservation, improves supply chain management, reduces food waste, and ensures food safety and quality in the fruit & vegetable industry.
