What are the causes of dust produced by the tablet press? 1. Dust is generated during the manual feeding process. 2. When the equipment is in normal operation, the process of upper punching: The dust generated is adsorbed by the plexiglass door, so the operator cannot see the pressing situation clearly. For normal production, the plexiglass door has to be opened, which is not in line with THE GMP standard. The uprush also gets into the dust. Powder adsorption lubricating oil due to the lack of oil and regular injection. If it is not cleaned in time, the up-rush and up-guide rail will often wear down, resulting in the equipment can not work normally. The dust generated by the equipment running for a long time will enter the electric control box and cause electrical faults. Dust will contaminate the stamping room, making it difficult to clean and disinfect. 3. During the operation of the equipment, dust in the stamping process is absorbed by powder suction nozzle, bu

Problems affecting the pressing and forming of the tablet press The special tablet press is another important factor in tablet forming. The performance of the tablet press, the mechanical operation of the equipment and the wear degree of the mold directly affect the quality of the tablet. According to the specifications and models, the pressure of the rotary pipepress is greater than that of the special pipepress for impacting profiles, the pressure is uniform, and the split phenomenon is easy to control. Due to the fixing of the cartridge, the machine vibration is small, the particle stratification is small, the tablet weight is accurate and stable. But this particular type of rotary tablet press also has several models of single-track and double-track. When there is a weight difference in the production of tablets, you should consider that your tablet press is a special type of machine with a double-track structure that makes the particle speed and compression time shorter than

How does the tablet press operate? Operators should first read the operating rules and operating instructions of the press, familiar with the performance of the press and the use of control parts. Stamping die should be checked strictly before normal use. Cracks, missing edges or deformation are not allowed. The installation should be properly tightened. Do not use if unqualified. The particle size of raw materials is an important factor for the success of pressed tablets. The pressing quality must be controlled according to the process requirements, otherwise it will affect the pressing quality and the normal operation of the machine. The speed of the tablet has an effect on the quality of the tablet and the life of the device. In general, for materials that are difficult to form, it is slower to choose tablets with large diameters and faster to choose tablets with small diameters. When no load, the volume of packing should be increased to prevent the upper and lower pu

What is the excipient classification of press tablets? What are the auxiliary materials of tablet pressing machine? How do you classify them? 1. Fillers: also known as diluents, mainly used to increase the weight and volume of tablets. Common fillers contain dextrin and starch. When the main drug in the filler is oil or liquid, the filler is added to absorb liquid, which is called absorbent filler. 2. Resolver: The tablet is quickly and effectively decomposed into the gastrointestinal tract immediately after ingestion, so that it can be dissolved and absorbed and play its curative effect quickly. Decomposition agents are hydrophilic objects, with good adsorption and expansion ability, commonly used starch and carboxymethyl starch. 3. Wetting agents or adhesives: After some drugs or auxiliary materials are wetted, they have enough viscosity to produce sufficient viscosity by adding appropriate liquid called wetting agent. If the drug is less sticky or less sticky on its own. When so

How to press the tablet hardness is not enough? Generally, tablets produced by the tablet press will have insufficient hardness, but this does not necessarily mean that the pressure of the tablet press is not enough, and there are some other factors: Factor 1: The amount of adhesive or lubricant is low or insufficient, resulting in uneven distribution of particles and stratification of coarse and fine particles. Even if the pressure increases, insufficient hardness of the tablet cannot be solved. Solution: choose the right adhesive or increase the dosage, improve the granulation process, mixing particles evenly, etc. Factor 2: Insufficient fineness of drug crushing, high fiber, elastomer or oil content, uneven mixture. Solution: can crush the finer drugs, adhesive can be selected, increase the tablet pressure, completely mix oil absorbent, etc. Factor 3: In the drying process, in the case of insufficient moisture, too little dry particles or too elastic, drugs contain

Do you understand the new functions of the tablet press? Foreign tablet presses the speed, the yield is high. High speed and high yield have been the goals of tablet forming for many years. The main plate-forming machinery already has machines that produce one million pieces per hour. If the domestic production of the tablet press, if the production speed of China's tablet press is faster than that of foreign countries, the need for large-scale tablet press innovative design and development, information processing, automatic control and other processes. Sealing of stamping process and isolation of personnel flow and logistics. The input and output of foreign presser are well sealed to minimize cross contamination. Particles enter the hopper through a closed drum and a closed transport system. Effective measures should be taken to prevent dust spatter and particle stratification during the pressing process. Most of the domestic pressing process is open or not completely closed, th

What are the factors that affect the quality of the press The press wheel is a device for adjusting the pressure of the press plate and increasing the protective effect. Common faults include wear of the pressure wheel, lack of oil or damage to the bearing of the pressure wheel shaft. Since the outer cylinder of the pressure wheel is obviously worn and the rod end resistance is high, the pressure wheel should be replaced again. The hole press wheel and the press wheel inside are very broken, the press wheel or the press wheel shaft should also be replaced: sometimes, the damage of the press shaft is mainly due to excessive pressure, most of the raw materials are difficult to press due to improper adjustment operation, then should replace the axial pressure, adjust the equipment must and should adjust the pressure. In addition, the pressure shaft bearing to regular lubrication and maintenance, if there is any damage, to replace in time. The common fault of overload protection syst

What needs to be improved about the tablet press Improvements to be made on the tablet press: The enterprise has made contributions to the smooth operation of the whole direct pressing process by improving the feeding device, dedusting device and prepressing device. Fine powder does not have good fluidity like particles, and it is easy to have void or fast or slow flow in the feeder, which leads to the difference of flake weight. The powder flows uniformly into the mold hole through vibrating feeding or forced feeding device; Because air is present in the powder, it is more easy to produce than granule extrusion head crack, reduce the extrusion speed, or through the secondary compression, which is a preliminary compression, the second final compressed into tablets can solve this problem, due to the increase of the compression time, facilitate powder after the discharge of ventilated take a breath, reduce the cracking phenomenon, improve the tablet hardness. In addition, because o
