Capsules production equipment The filling of the drug is the most critical step in the manufacturing process of preparing the capsule. 1. Treatment of drugs (1) small dose of drugs or fine material drugs can be directly crushed into fine powder, through the six sieve, after mixing and filling. (2)large dosage of drugs can be partially crushed into fine powder, the rest of the medicinal materials extracted into thick paste and drug powder after mixing, drying, grinding, screening, mixing after filling. All the medicinal materials can also be extracted and concentrated into an extract, and then add appropriate auxiliary materials to make small particles, and then dry and mix and fill. (3) volatile oil should first be absorbed with absorbent or other drug powder in the prescription after filling, or after filling. (4) The drugs that are easy to be wet or eutectic after mixing can be diluted with an appropriate amount of diluent and then filled. (5) loose drugs are generally made in

Characteristics of capsules A capsule is a preparation containing a drug in the form of a capsule by dose. Gelatin is usually the main material of capsule, sometimes to change its solubility or to achieve intestinal solubility, etc., there are also methyl cellulose, calcium alginate, modified gelatin, PVA and other polymer materials. The capsules mask the drug's unpleasant smell and are easy to swallow. To improve the stability and bioavailability of drugs; It also regulates and localizes drug release and can compensate for other widely used solid formulations. No drug should be made into a capsule because it is soluble in bagged material, wears away easily, and is very irritating. Characteristics of capsule: 1. It can mask the odor of a drug or improve its stability. To be isolated from the outside world, to avoid the influence of moisture, air and light, and to have a certain degree of shielding, protection and stability for odorous or unstable drugs; 2. Improve the bioav

Development of capsules The preparation process of Traditional Chinese medicine is divided into two parts: extraction process and molding process. In order to solve the common problems in the production of traditional Chinese medicine capsule preparations, some Chinese scholars put forward the concept of "granulated capsule" (such as biscuit). Assuming that the total volume capsule is M V and the prepared daily dose is according to the formula M = P V, we know that with M, it is necessary to reduce the particle heap density required by the increase of V, that is to say, reducing the number of particles significantly increases the particle density. If the prepared particles have small specific surface area, smooth and round appearance, dense texture, not only waterproof, but also easy to package. Membrane coating can not only improve the moisture resistance of particles more effectively, but also change the external color of particles through the packaging of special materials t

Classification of capsules Capsule is divided into soft capsule and hard capsule commonly, hard capsule has gelatin capsule and plant capsule again cent. The hard capsule is composed of two exquisitely processed capsule shells. Capsules come in different sizes, including capsule Numbers 000#, 00#, 0# -5 #. The printed text can also be coloured on the capsule to give a unique and personal feel. One part of the capsule body has a tapered edge, allowing the capsule to be gently encapsulated in a high-speed filling machine. Double closed loop system can make the capsule sealed before filling and completely sealed after filling. The capsule is also designed to include permeable holes to prevent unnecessary air pressure entering the capsule during the high-speed filling process, resulting in a reaction. Plant capsule is a hollow capsule made of plant cellulose or water-soluble polysaccharide to meet the needs of preparation and localization of the capsule. It retains all the a
