Principle of food desiccant

Introduction: many people know that food desiccant is used in many food industries, which is closely related to food production and processing What is the principle of food desiccant? The principle of food desiccant is to use the water absorption of some substances to absorb the water in the environment into its own structure The specific content is introduced by the staff of Baibai safety net Physical adsorption: desiccant is suitable for preventing the instruments, meters, electrical equipment, drugs, food, textiles and other packaging materials from getting damp Desiccant is also widely used in the sea transportation, because the goods are often affected with damp and deterioration due to the high temperature in the transportation process The use of desiccant can effectively dehumidify and moistureproof, so that the quality of the goods can be guaranteed Chemical adsorption; acid desiccant: concentrated sulfuric acid and phosphorus pentoxide are used to dry acid or neutral gas, in which concentrated sulfuric acid can not dry strong reducing acid gas of hydrogen sulfide, hydrogen bromide and hydrogen iodide, and phosphorus pentoxide can not dry ammonia gas Neutral desiccant: anhydrous calcium chloride, general gas can dry, but anhydrous calcium chloride can not dry ammonia and ethanol Alkali desiccant: alkali lime (mixture of Cao and NaOH, KOH), quicklime (CAO), NaOH solid, used to dry neutral or alkaline gas What are the working principles of food desiccant described above, and what are the hazards of desiccant? If you take it carelessly, it still has certain harm You need to go to the hospital in time for detailed inspection and treatment If you are worried that the daily life products contain such harmful substances, the food safety tester is the best testing instrument
