Adsorption treatment process of harmful substances in cooking pots

Abstract

The application relates to the field of kitchen utensils, and specifically discloses an adsorption treatment process for harmful substances in a cooking pot. Mixing to obtain adsorbent; S2, melting: the pig iron block and the adsorbent are melted together, and stirred to obtain molten iron, and the melting temperature is 1700-1850 ° C; S3, slag removal: the molten iron is stirred and slag removed; wherein, the adsorption The dosage of the agent is (2.5-12.0) kg / ton of pig iron. The method has the advantages of short melting time of pig iron blocks, good slag accumulation effect, and less harmful impurities in the prepared iron pot.

Description

technical field [0001] The present application relates to the field of kitchen utensils, and more particularly, it relates to the adsorption treatment process of harmful substances in cooking pots. Background technique [0002] The pots used for cooking are divided into iron pots, stainless steel pots, Maifan stone pots, etc. according to their materials. Among them, iron pot is the main kitchen utensil for cooking food, and iron pot is divided into cast iron pot and wrought iron pot. The cast iron pot is made of gray iron melted and cast with a model. The heat transfer is slow and uniform, but the pot ring is thick and the texture is rough; , Fast heat transfer and beautiful appearance. [0003] Among them, the gray iron used in pig iron pots contains iron-carbon alloys with a carbon content of more than 2%. In addition, there are 1% to 3% silicon and phosphorus, sulfur, lead, arsenic, antimony, mercury, and vanadium in cast iron. , nickel, chromium, molybdenum, copper, ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the above-mentioned iron-carbon alloy is used to prepare a pig iron pan. During use, the pig iron pan will be in contact with a large amount of media such as acid, alkali, and salt, and it needs to be heated to a certain temperature. It is precipitated during cooking, and the substances enter the human body through food as a medium. These substances contain a large amount of heavy metal elements. Long-term use will cause the heavy metal content in the human body to exceed the standard, which is very harmful to humans.
