To improve the quality of products, three factors should not be ignored in the process of tablet pressing of traditional Chinese Medicine

[technical article of pharmaceutical Station] the research and production of traditional Chinese medicine tablet began in the 1950s Under the comprehensive research of traditional Chinese medicine chemistry, pharmacology, preparation and clinic, the variety and quantity of traditional Chinese medicine tablet are increasing, the technology is improving day by day, and the quality of tablet is improving gradually According to the introduction of relevant experts, there are many advantages of traditional Chinese medicine pressed into tablets, such as the dissolution rate and bioavailability of tablets are better than pills; the dosage is accurate, and the content difference of drugs in tablets is small; mechanized production, large output, low cost, easy to reach the "health standard" For example, the quality is stable, the tablet is a dry solid, and some drugs that are easy to oxidize, deteriorate and deliquesce can be protected by coating Therefore, light, air, water and other factors have little impact on it; it is more convenient to carry, transport and take In the process of traditional Chinese medicine tablet pressing, the quality of finished product is mainly affected by these factors, including fluidity, formability and lubricity If the fluidity is good, the powder operation such as flow and filling will be carried out smoothly, and the difference of tablet weight will be reduced; if the compression formability is good, there will be no bad phenomena such as cracks; if the lubricity is good, the tablet will not stick and wash, and the enterprise can also get a complete and smooth tablet Benefiting from the advantages of traditional Chinese medicine tablet press, the traditional Chinese medicine tablet press also ushered in a broad market opportunity The main motor of traditional Chinese medicine tablet press is driven by AC frequency conversion stepless governor, and the turntable rotates after being decelerated by worm gear The rotation of the turntable causes the upper and lower punch to move up and down relative to each other under the action of the guide rail The particles are pressed into tablets by filling, top pressing, main pressing and tablet discharging In the whole pressing process, the control system realizes the automatic control of the weight of the tablet, the automatic elimination of the waste tablet and the automatic sampling through the detection, transmission, calculation and processing of the pressure signal, so as to display the fault and print various statistical data At present, the characteristics of traditional Chinese medicine tablet press are high speed, high output and good tablet quality Double pressure and microcomputer control are adopted in tablet pressing, which can continuously press granular materials In addition to being able to press the common original piece, it can also press the special-shaped piece of various shapes It has the characteristics of full sealing, high pressure, low noise, high production efficiency, perfect lubrication system, automatic operation, etc According to the introduction of relevant manufacturers, the turntable is the main executive part of Chinese medicine tablet press, which consists of upper and lower bearing components, main shaft, turntable and other main parts The torque between the turntable and the main shaft is transmitted by the flat key The track is composed of a cylindrical cam and a plane concave wheel, which is the track of the up and down punch The upper track is composed of upwash up track, upwash down track, upwash up parallel track, upwash down parallel track and press down rail They are respectively fastened on the upper track plate, and the lower track is composed of the down wash up track, down wash up track and filling track Nowadays, tablet has become one of the dosage forms with many varieties, large output, wide application, convenient use, storage and transportation, and stable quality Tablet has been recorded in Pharmacopoeia of China and other countries, accounting for more than 1 / 3, which shows wide application range Traditional Chinese medicine is the treasure of our country Under the influence of the improvement of people's health care consciousness and the enhancement of the attribute of consumer goods, traditional Chinese medicine in the form of tablet has become the "pet" of the market In the aspect of tablet production technology, relevant enterprises have gradually explored a set of technological conditions suitable for the production of traditional Chinese medicine tablets, such as the preparation of tablets containing fat oil and volatile oil; how to improve the hardness, disintegration and coating of traditional Chinese medicine tablets, many enterprises are gradually accumulating experience and improving product quality.
