Description

Technical Field

[0001] The invention relates to the technical field of food processing and packaging, and in particular to a method and a device for preparing an iron-based absorption-release deoxidizer. Background Art

[0002] There are many types of deoxidizers. The most common one relies on iron powder to carry out oxidation reaction to remove oxygen in the space and prevent the oxidation and deterioration of related stored items. The deoxidizer can react with oxygen to reduce the oxygen concentration in the corresponding food sealed packaging container within a specified time and can maintain the fixed packaging product for a certain period of time. The absorption and release type means that when the deoxidizer reacts with oxygen, a certain amount of carbon dioxide is released at the same time. The absorption and release ratio refers to the volume ratio of carbon dioxide released by the deoxidizer to the oxygen absorbed.

[0003] In this regard, China's patent application number: CN113908769B discloses a production device for an environmentally friendly deoxidizer and a method for preparing an environmentally friendly deoxidizer, including: a support base, an extrusion cylinder, a mixing cylinder, an electric telescopic rod, a piston extrusion plate, a support plate and a molding mechanism. The extrusion cylinder is fixedly connected to the support base. The electric telescopic rod is fixedly connected to the extrusion cylinder. The mixing cylinder is fixedly connected to the electric telescopic rod. The piston extrusion plate is slidably connected to the extrusion cylinder. The support plate is horizontally attached to the extrusion passage. The molding mechanism includes: a hemispherical groove, a second one-way air valve, a connecting pipe, a step-by-step extrusion mechanism, a rubber sealing plate, an electric hot air blower and a first one-way air valve. The hemispherical groove body is evenly opened to the piston extrusion plate and the support plate. The second one-way air valve is installed on the piston extrusion plate. The rolling ball shell is a hollow shell. The benefit of the present invention is that it is convenient and quick to process to obtain a spherical deoxidizer, improve processing efficiency, and reduce energy consumption.

[0004] However, in actual use, the deoxidizer cannot release a certain amount of carbon dioxide, so the overall deoxidation effect is poor, and the sealing performance needs to be further improved.

Then the medicine liquid will be transported to the top of the rotating plate 21 and the guide inclined plate 22. At this time, the screw body 5 is in a rotating state, and then through the first rotating roller 16, the belt body 17 and the second rotating roller 18. The connecting rod 20 is designed to rotate, and the position of the second rotating roller 18 is limited by the design of the stable bearing 19. Then the connecting rod 20 drives the rotating plate 21 to rotate. When the liquid medicine falls on the surface of the rotating plate 21, a part of the liquid medicine can be thrown out through the rotation of the rotating plate 21, and the other part of the liquid medicine will be guided from the surface of the guide inclined plate 22 to fall into the interior of the preparation tube 3. When the rotating plate 21 rotates one circle, its surface will contact the lower surface of the scraper 23, and the scraper 23 can scrape off the residual liquid medicine on the surface of the rotating plate 21. In order to avoid residual liquid medicine, the present design realizes intermittent delivery of the liquid medicine, and when the liquid medicine falls into the preparation tube 3 after being delivered, the liquid medicine is dispersed into the preparation tube 3 through the rotation of the rotating plate 21 and the guide inclined plate 22, and finally, the liquid medicine is scraped off the surface of the rotating plate 21 through the friction between the rotating plate 21 and the scraper 23, and then the whole liquid medicine is fully stirred through the rotation of the screw body 5, and after the full stirring is completed, the material is discharged through the discharge pipe 35, and then the sealing and packaging operation is completed. The above is all the working principles of the present invention.
