Embodiment 1

[0016] Vanilla volatile oil: Weigh 10 portions of fresh vanilla leaves, crush them with a cooking machine, and transfer them completely into a 1000mL distillation flask, inject 10 to 15 times the volume of distilled water, install a volatile oil extractor, distill for 2 hours, stop heating and continue to pour in condensate The water is refluxed until no liquid drips from the condenser tube. When natural stratification occurs in the extractor, take out the oily substance in the upper layer, add an appropriate amount of anhydrous sodium sulfate, and let it stand overnight to remove the residual moisture in the volatile oil to obtain the vanilla volatile oil, which is then sealed and stored in a refrigerator at 4°C and protected from light until use.

Embodiment 2

[0018] Weigh 13 parts by mass of licorice, 18 parts by mass of bellflower, and make 13 parts by mass of dried orange peel with a particle size of 100 to 130 μm, and 14 parts by mass of radish, pulverize, grind, and sieve to make a powder with a particle size of 10 to 80 μm , and mix evenly, then add 24 mass parts of water, 30 mass parts of Guanyin soil, 20 mass parts of calcium carbonate, 10 mass parts of ammonium sulfate, 9 mass parts of β-carotene, 8 mass parts of soluble starch, 10 mass parts of vanilla volatile oil, After fully mixing and stirring, the mixture is sent to a screw extruder coated with kerosene in advance for extrusion, the extruded chalk is cut according to the required length and dried, and the dried chalk is immersed in a 10wt% aqueous solution made of polyvinyl alcohol , and then dry to get the medicated powder chalk of the present invention.

Embodiment 3

[0020] Weigh 10 parts by mass of licorice, 20 parts by mass of bellflower, and make 11 parts by mass of dried orange peel with a particle size of 100 to 130 μm, and 17 parts by mass of radish, pulverize, grind, and sieve to make a powder with a particle size of 60 to 100 μm , and mix evenly, then add 26 parts by mass of water, 26 parts by mass of Guanyin soil, 23 parts by mass of calcium carbonate, 6 parts by mass of ammonium sulfate, 11 parts by mass of beet red, 6 parts by mass of soluble starch, 8 parts by mass of ethyl lactate, fully After mixing and stirring, the mixture is sent to a screw extruder coated with kerosene in advance for extrusion, the extruded chalk is cut off according to the required length and dried, and the dried chalk is immersed in a 10wt% aqueous solution made of polyvinyl alcohol. After drying again, the medicated powder chalk of the present invention is obtained.

Abstract

The invention discloses a traditional Chinese medicine-containing chalk. The chalk is prepared from the following components in parts by mass: 26-34 parts of kaolin, 15.7-23 parts of calcium carbonate, 6-14 parts of ammonium sulfate, 10-16 parts of licorice roots, 16-20 parts of platycodon grandiflorum, 11-16 parts of pericarpium citri reticulatae, 10-17 parts of semen raphanin, 7-11 parts of calcium sulfate, 6-10 parts of soluble starch, 8-12 parts of a flavoring agent and 21-26 parts of water. The chalk has the effect similar to those of medicinal chalk but does have the side effect of medicinal ingredients since traditional Chinese medicinal materials and volatile oil ingredients are added based on existing conventional chalks.

Description

technical field [0001] The invention relates to the field of teaching, in particular to a chalk containing traditional Chinese medicine. Background technique [0002] Chalk is a tool widely used in daily life and is generally used for writing on blackboards. Ancient chalk was usually made of natural chalk, but nowadays it is replaced by other substances. The composition of chalk is a white precipitate of calcium sulfate, which is not easily decomposed, and the particles are larger than dust. Now, the chalk of domestic use mainly contains two kinds of common chalk and dust-free chalk, and its main component is calcium carbonate (limestone) and calcium sulfate (gypsum), or contains a small amount of calcium oxide. The function of chalk is to write and draw on the blackboard, and it has the function of disseminating knowledge. It will selflessly dedicate knowledge to everyone. Ordinary chalk is about two inches long, with a thick end and a thin end in the shape of a truncate...
