Weight adjustment of tablet for tablet press During the stamping process, the weight difference of the tablets tends to increase. What should be done? (1) Punch length is not uniform: the workpiece weight difference may increase, so calipers should be used to check whether each punch is qualified. If individual reductions may be due to failed discharge movements and low particle fill volumes, individual reductions should be checked well to remove obstacles. (2) the hopper level unit is wrong: may result in a hopper particles falling rapidly, the particles on the feeder, another hopper slow accumulation of particles, the particles on the feeder, less lead to imbalance, joining the two particles hopper production, hopper position is adjustable, must maintain a certain number of particles and lose speed, the accumulation of two hopper about the number of particles, particles can join hole. (3) Feeding hopper blockage: in the buffer zone of the tablet, if the particles are stic

The influencing factors of the structure of the capsule filling machine The influences of the loading amount of the capsule filling machine are generally the preset position of the filling rod, the filling material, the loose density of the material and the pressure of the filling rod. General measuring tray has six station filling hole and the corresponding filling bar, with five bar filling powder compaction, there is a station filling bar within the measuring cylinder pressure into the hole of the powder capsule, the five station filling bar preset position determines the pressure into the powder weight measuring hole and thus into the filling bar preset position. Due to the difference of the smoothness, particle form and state of the material itself, the amount of the capsule is also different under the same measuring hole, preset depth of the filling rod and the pressure of the filling rod. The state of the material can be adjusted according to the previous experience, and some

Blister packing machine blow molding Blister packaging machine blow molding is a kind of plastic processing, its main principle is the plastic film after heating soft, vacuum attached to the mold surface, cooling molding, widely used in plastic packaging, lighting, medicine and other industries. Blister packaging products mainly include: flat blow molding box, also known as vacuum chamber, blow molding packaging equipment, pressure blow molding machine, etc. The rigid transparent plastic sheet is transformed into a specific concave plastic by the blow molding process and placed on the surface of the product for protection and beautification. The surface of the ordinary hard plastic film and a layer of soluble material are bonded together to make the surface of the tray soluble, so as to improve the quality of packaging. Mold production blow plaster mold, the cost is lower, followed by galvanized copper template, the more expensive is aluminum template. We often talk about blow mo

Filling accuracy of capsule filling machine At present, most of the domestic capsule filling machines are standard models of quantitative filling. The filling volume is determined by the thickness of the measuring plate and depends on the free density of the filling material. At the same time, the accuracy of filling quantity control is related to the influencing factors of filling structure and filling material itself. The hygroscopicity of the filling material is a factor affecting the control accuracy. When the filling powder or particle viscosity is too high and the fluidity is poor, the viscosity will produce plug powder. Usually, during the process of the mixed filling of any drug powder or particle, the humidity will be controlled below 3%. In addition, the moisture absorption capacity of the filler is related to its critical relative humidity. Generally speaking, when the purity of filling powder or particle is not high, its critical relative humidity decreases and multi-

The tablet quality of the tablet press In addition to particle quality, production environment and operator proficiency, tablet quality is closely related to the state of the machine. Therefore, it is important to keep the machine in good working condition. The following provisions shall be observed: Before starting the operation, the staff shall ensure good lubrication according to the lubrication mark, lubrication position and oil amount specified in the lubrication chart and the fuselage manual. Strictly implement SOP operation of equipment. After the end of the daily work, wipe the powder remaining in each part of the machine clean and clean the machine carefully. When the mold is disassembled or installed, be careful not to impact the mold to avoid defects. Regular inspection of worm, worm and other components, found defects timely repair or replacement. Computer controlled tablet presses should be shut down in strict accordance with the shutdown procedure to

Check the capsule filling machine before use The machine is vibration machinery, should often check the screw fixation of each part. If it is loose, it should be tightened in time to avoid damage. Plexiglass components (work table, cover plate) should avoid direct sunlight in high temperature, heavy objects should not be stacked. Cover plate should be vertical or flat to avoid deformation and damage. At the end of each day, the machine and mold should be cleaned on the hole, keep the machine clean, avoid washing the main machine with water. If you need to clean the mold, please loosen the screws and take it down for easy installation. Lock the reducer in. The first change is within 24 hours and the second within 72 hours. Then replace it once a month. When the machine is locked in mold change mode, that is, the middle part of the rotation, the production plate height difference, 0#1#2 # is clockwise rotation, therefore, 2#1#0# is in the opposite direction of the clock.

Adjuvants in tablets The most commonly used adjuvants in tablet preparation are fillers, thinners, adhesives, lubricants and disintegrants. Diluents and adsorbents, collectively known as fillers, are used to increase the weight and volume of a tablet. If the drug itself is sticky, particles can only be made by adding a wetting agent. The most common fillers or thinners are starch, powdered sugar, dextrin, cream, compressible starch, microcrystalline cellulose, and inorganic salts. Some powder itself is not viscous or low viscosity, need to add a sticky substance, such as starch paste, to bond together. Commonly used adhesives: ethanol, starch pulp, sodium carboxymethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose; In addition to oral, sublingual, palliative, and controlled-release tablets, a disintegrating agent is often required. These tablets need to be dissolved and released slowly. Common disintegrating agent: dry starch, carboxymethyl starch so
