Problems solved by technology

[0010] A. This method cannot be used for the recovery of granules, small tablets, micropills, microcapsules, and mixture materials, because the pulverization method will seriously damage the integrity of the shape of granules, small tablets, micropills, microcapsules, etc.
[0011] B. Products whose capsules are filled with pharmaceutical powder will be mixed with a large number of finely divided capsule shell fragments after crushing, which will affect the content of active ingredients in the drug after refilling
[0012] C. A large number of broken capsule shells mixed in the powder recovered after crushing will make the density of the powder uneven, resulting in weight differences between products after refilling. At the same time, finely divided capsule shells will affect the smoothness of the filling process.
[0013] D. During the crushing process, the powder scatter seriously, and the recovery rate of the powder is low

Embodiment Construction

[0027] A capsule dismantling method, the capsule to be disassembled is put into a pressure container; the pressure container is filled with compressed air, so that the high-pressure compressed air enters the capsule from the gap between the capsule body and the capsule cap; and then quickly Reduce the pressure in the pressure vessel, so that the high-pressure air inside the capsule will expand rapidly due to the sudden pressure difference between the inside and outside, and the expansion force from the inside to the outside of the capsule will separate the capsule body and capsule cap. After filling the pressure vessel with compressed air, the high-pressure compressed air first flattens the capsule radially and enters the capsule from the gap between the capsule body and the capsule cap, so that the air pressure inside and outside the capsule is gradually balanced and maintained. With higher pressure. The crushed capsule body and capsule cap recover to the shape before being c...

Abstract

The process for extraction consists the steps of, identifying the source of the raw material, extracting and concentrating the raw material, mixing the extractive with thin layer silica gel by the proportion of 1:1, loading column by the ratio of sample : thin layer chromatography silica gel = 1:0.5, and washing with expansion agent. The invention realizes an extraction process with an increased standard body purity.

Description

technical field [0001] The invention relates to a capsule disassembly method and equipment. Background technique [0002] In the prior art, with the continuous development of the pharmaceutical industry, the variety and output of medicines and health care products are increasing rapidly. Capsules are more and more widely used in solid preparations due to their own advantages. Capsule filling machines have been continuously improved and developed, and the filling speed of capsule products has been continuously improved. At present, nearly 3,000 domestic pharmaceutical and health care products companies produce about 70 billion capsule dosage products annually. [0003] However, due to the constraints of various other factors, the average qualified rate of one-time filling of capsule products by domestic enterprises is only 95%. In order to save costs and reduce the loss of medicinal materials, enterprises will disassemble and recycle 5% of unqualifi...
