Adsorption treatment process for harmful substances in cooking pot

Abstract

The invention relates to the field of kitchen utensils, and particularly discloses an adsorption treatment process for harmful substances in a cooking pot. The adsorption treatment process for the harmful substances in the cooking pot comprises the following steps of S1, preparing an adsorbent: mixing limestone powder, aluminite powder, fluorite powder, phosphate and an adhesive to obtain the adsorbent; S2, melting: melting pig iron and the adsorbent together and stirring to obtain molten iron, wherein the melting temperature ranges from 1700 to 1850 DEG C; and S3, deslagging: stirring and slagging off the molten iron, wherein the adding amount of the adsorbent is (2.5 to 12.0) kg / ton of pig iron. The adsorption treatment process for the harmful substances in the cooking pot has the advantages that the pig iron melting time is short, the slag accretion effect is good, and a prepared iron pot contains few harmful impurities.

Description

technical field [0001] The application relates to the field of kitchen utensils, and more specifically, it relates to an adsorption treatment process for harmful substances in cooking pots. Background technique [0002] The pots used for cooking are divided into iron pots, stainless steel pots, medical stone pots, etc. according to their materials. Among them, iron pans are the main kitchen utensils for cooking food, and iron pans can be divided into raw iron pans and wrought iron pans. Cast iron pots are made of gray iron melted and poured with molds. The heat transfer is slow and uniform, but the pot rings are thick and the texture is rough; , fast heat transfer and beautiful appearance. [0003] Among them, the gray iron used in the pig iron pot is an iron-carbon alloy 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.
