How to make Chinese medicine water pill?

The method of making water pills water pills are prepared by the pan system method. There are two types of pan system methods: manual pan pills and mechanical pan pills, which operate on the same principle, mainly raw material processing and crushing, molding, molding, selecting the cover surface, drying, coating, lightening, and quality inspection. One of the mold is a key step. 1. raw material processing and crushing: the prescription of each drug according to the requirements of processing and shelling qualified for crushing, through a 100-mesh sieve, standby. 2. mold: pill mold is the basis of the pan-pill molding method. There are two methods of mold and mechanical mold after work. (1) manual mold: in a clean and dry bamboo plaque 1/4, with a brush dipped in a little water coated evenly so that the plaque surface wet, sprinkle a small amount of powder on the wet plaque surface, with both hands to hold the plaque, rotate the bamboo plaque, so that all the drugs wet, and then gently brushing down the brush in turn (i.e., gently adjusted with the tip of the brush), turn the bamboo plaque, the wetted particles moved to the other side (dry plaque), sprinkled a small amount of fine powder and shake the bamboo plaque so that the small particles all evenly coated with medicine powder. particles all evenly coated with powder and shaken to another place, and in the original coated water on a small amount of water, and then powdered particles moved to the coated water out of the rolling, all the water on the water, and then turn to another dry place, sprinkle fine powder, and then turn the bamboo plaque, so that the wet particles are all rolled on the powder, so so many times repeatedly until the formation of a more dense small garden particles (such as the size of the diameter of about 0.5-1mm), do not stain the plaque, the plaque mold that is formed, and then increased the molding of the plaque. Selection of uniform and then increase the molding. (2) mechanical mold: the powder spread in the coating pot, the coating pot rotation will be sprayed into the water, so that all the powder into wet small particles, and then add a small amount of fine powder, continue to roll for a certain period of time, so that the small particles are solid, micro-dense, and then spraying the powder, and then repeated operations, that is, the rules of the pill mold, screened and then continue to molding, (or the first appropriate amount of water poured into the pot, and then if the appropriate amount of powder, evenly spread over the entire pot, and then use a brush to increase molding. The whole pot, and then gently brush down with a brush from the opposite direction, that is, to get loose pieces, gently rubbed by hand, so that the large broken continue to repeat the operation can be into the pill mold. 3. Increase the molding: mold made by repeatedly rotating the bamboo plaque, and alternately add water and powder, and constantly rotate the plaque, the whole basic action that is the kneading group, bumping over, alternately, in order to strengthen the hardness of the pill particles and the degree of roundness until the pill particles are gradually increased in size and molded to meet the requirements until the pill particles are gradually increased in size. Meet the requirements until. (Manual and mechanical the same said) 4. Selection of pills: with the appropriate medicine sieve will be screened evenly all the time pills, too small pills and then pan large, too large deformities should be separated for appropriate treatment. 5. cover: cover the surface of the purpose is to make the surface of the pills dense, glossy, color and luster. Commonly used methods are dry powder cover surface, water cover surface and clear pulp cover surface three kinds. 6. drying: because of the large amount of water pills, should be dried in a timely manner (below 60 degrees). Drying should gradually rise in temperature, and constantly turning, so as not to produce yin and yang surface. Part II: First, the mother pill: the mother pill for the foundation of the pan pill particles, is the key to making water pills. First of all, a little cold water or spray or wipe in the plaque (water pill sieve), then sprinkle a small amount of powder, so that all the powder is wet and evenly adhered to the powder, with a dry brush to slowly brush down the powder to form small moist particles, and then add a small amount of powder, so that the particles with the plaque of the pendulum, and gradually increase the rounding. So spray water with powder repeated operation about twenty times, that is, there are fine pills appear. Second, the pan pill: take the mother pill according to the above method in the tablet repeated operation, add powder and adhesive, about 20 times can be the size of perilla in the pill, and then pan a hundred times can be the standard size of the water pill. Pay attention to the swing of the tablet, make sure that the surface of the water pill is smooth and uniform size. Third, drying: made of water pills, should be promptly dried at low temperatures, containing aromatic drugs should only be placed in a ventilated place to dry. Fourth, coating and lightening: to be coated, the dry water pills, wet with the appropriate liquid, add coating materials rotary coating, and then low-temperature drying. Those who need to lighten, rotating lightening, so that the surface of the pill is moist with gloss. V. Packaging: water pills in closed containers or plastic bags, to prevent moisture, high temperature and insect pests. Attention to time: a mother pill is the key to the production of water pills, the mother pill requires uniform size, shape and neat. Containing viscous herbs are not easy to start the mother, can be prescribed in the low viscosity of the drug to start the mother, such as licorice. Second, the mother and pan pill process, add water should be appropriate. More viscous powder with less water, more fibrous powder, more water. Third, in order to seek uniformity in the size of water pills, in the process of pan pills must pay attention to the screening of pills too small to sieve out a separate increase. Fourth, the pan pill rotation should be appropriate, if the rolling time is too long, the pill is too tight not easy to disintegrate, rolling time is too short, the pill is loose and easy to crack. Fifth, the pan pill operation should be carried out continuously, can not be put dry and then increased, otherwise easy to peel off the separation. Synthesize it to master the production method.
