Problems solved by technology

However, in a dry heat state, due to poor thermal penetration and strong heat resistance of bacterial endotoxins, it must be subjected to high temperature for a long time to achieve the purpose of sterilization
However, when the temperature is greater than or equal to 140°C, the activated carbon will spontaneously ignite under aerobic conditions, and dry heat sterilization cannot be performed. At the same time, the stirring effect of the sterilizer is poor, and the activated carbon cannot be uniformly heated.

Abstract

The invention discloses a production process of activated carbon for injection. The activated carbon for injection, which is produced by crushing, sterilizing, inspecting, internally packaging and externally packaging the activated carbon, has the characteristics of high decoloration speed, high adsorption capacity, developed internal pore structure and the like, and can effectively adsorb pigments, microorganisms and bacterial endotoxin in liquid medicine, reduce impurities in the liquid medicine, and does not affect the concentration and property of other components of the liquid medicine. The activated carbon powder is taken and packaged after being inspected to be qualified, a medical low-density polyethylene film bag is adopted firstly, then a PE film bag is arranged outside the medical low-density polyethylene film bag in a sleeving mode, it is guaranteed that the activated carbon powder is isolated from air, and the moisture content in the activated carbon powder is prevented from rising; The heating cavity and the stirring cavity are formed in the barrel, and the heat-conducting medium is arranged in the heating cavity, so that conduction heating can be performed on the interior of the stirring cavity, and the heating uniformity of the activated carbon is improved. Meanwhile, the stirring blades are arranged in the stirring cavity and continuously stir the activated carbon, so the activated carbon is uniformly heated.

Description

technical field [0001] The invention relates to the technical field of activated carbon processing, in particular to a production process of activated carbon for injection. Background technique [0002] As a functional carbon material with strong adsorption capacity, activated carbon is mainly used in food and beverage, medicine, water treatment, chemical industry and other fields. Pharmaceutical activated carbon is a new type of activated carbon specially used in the pharmaceutical field, mainly used in the pharmaceutical process Decolorization of medium solution and adsorption of impurities and small molecule heavy metals in solution are the most commonly used means to remove heat source. This kind of activated carbon is usually used in the field of medicine, so it is called "medicinal activated carbon". Its biggest characteristics are fast decolorization speed, strong adsorption capacity, and developed internal pore structure, which can effectively absorb the pigment in t...
