Problems solved by technology

The disadvantage of this reaction is an exothermic reaction, which releases heat while absorbing oxygen, causing water to evaporate, thereby increasing the humidity in the package. For food and medicine that require a dry environment to deoxidize and keep fresh, the humidity in the packaging bag is particularly important.

Abstract

The invention relates to an anhydrous hydrogen-restraining type deoxidizer. On the basis of maintaining a molten iron system electrochemical reaction, a water absorption hydrogen-restraining agent is applied to the deoxidizer, and calcium chloride and a calcium hydroxide compounding agent, which can absorb moisture are added to a deoxidizer granule mixture, so that the anhydrous hydrogen-restraining type deoxidizer absorbs oxygen while absorbing moisture through an electrochemical reaction, and restrains generation of hydrogen. According to the anhydrous hydrogen-restraining type deoxidizer disclosed by the invention, the problem that a conventional deoxidizer enables food moisture in a pack to be dissipated due to heating in a deoxygenization process, can be solved, and the invention can provide the anhydrous hydrogen-restraining type deoxidizer which can maintain inner parts of bags dry, prevent generation of hydrogen, and have good deoxygenization and fresh-keeping effects.

Description

technical field [0001] The invention relates to an oxygen scavenger, in particular to an anhydrous hydrogen suppression type oxygen scavenger. Background technique [0002] With the reform and opening up of our country and the improvement of people's living standards, the application range of deoxygenation preservation technology and oxygen scavenger has become more and more extensive. Now oxygen scavenger has been widely used in the preservation of food and medicine; Remove the oxygen in the food sealed bag, so that the oxygen concentration is reduced from 21% to below 0.1%; the action mechanism of the oxygen scavenger is an electrochemical reaction, iron powder is used as the main raw material, and it passes through an electrochemical medium and contacts with water to undergo an electrochemical reaction , the reaction continues while absorbing oxygen. The disadvantage of this reaction is an exothermic reaction, which releases heat while absorbing oxygen, causing water to ...
