Gas conditioners refer to the regulation of the gas composition in a controlled atmosphere storage, wherein the preparation of oxygen and carbon dioxide gas is mainly a preparation. (1) Deoxidizers In the storage and preservation of fruits and vegetables, the use of deoxidizer must be matched with the corresponding breathable and moisture-permeable packaging materials such as low-density polyethylene film bags, polypropylene film bags, KOP (polyethylene, vinylidene chloride, polypropylene layer). Pressure film bags are used together to achieve better results. 60 grams of iron powder, 10 grams of ferrous sulfate (FeSO7HO) 7 grams of sodium chloride, 23 grams of soy flour mixed evenly (larger in proportion to this ratio), packed in a breathable pouch, and loaded with fresh fruits and vegetables to be preserved Plastic and other containers can be sealed. Generally 1g of preservative can remove 1000ml of oxygen in a confined space. (2) Carbon dioxide generating agent: A mixture of 73 g of sodium bicarbonate, 88 g of malic acid, and 5 g of activated carbon is mixed and mixed (amount is more than this proportion) to obtain a fruit and vegetable preservative capable of releasing carbon dioxide gas. In order to facilitate the use and give full play to the effect of preservation, preservatives should be packaged into 5 to 10 grams of pouches. When used, it can be sealed together with fresh fruits and vegetables in containers such as polyethylene bags and corrugated paper boxes. (3) Deoxidation (carbon dioxide generation) agents These types of preservatives are characterized by the production of carbon dioxide gas at the same time as deoxidation, resulting in a low oxygen and high carbon dioxide storage environment. 200 grams of iron powder, 120 grams of ferrous chloride, 200 grams of sodium bicarbonate, 80 grams of phthalic acid, and 200 grams of bentonite are mixed together (a large amount is formulated according to this ratio) and filled with air permeability. Can be put into use in the pouch. This preservative is characterized by the ability to remove oxygen and produce carbon dioxide gas. Put fruits and vegetables into a low-density polyethylene film bag with a thickness of 0.02 to 0.04 mm. At the same time, place a preservative at a dose of 3 to 8 g/L. After being sealed and stored at room temperature, low oxygen and high carbon dioxide gas can be produced. Atmosphere storage environment.
