Xianghe Pharmaceuticals seizes development opportunities and is committed to solving the problem of film machine dust
The dust problem is a headache for the tablet press industry, but the effective treatment methods have not been born. It is well known that there are many kinds of tablet presses in China. These tablet presses generally use a special vacuum cleaner to provide negative pressure to pump them in the dust produced. exclude. However, due to the gap between the existing technical level and the consciousness, the sealing effect of the equipment itself is not satisfactory, and some dust is still leaked to the purification area. In addition, the dust generated by the process of material conveying or tablet transfer may also be directly leaked from the relevant joint to the purification area.
Xinghua Xianghe Pharmaceutical Machinery Co., Ltd. develops and produces tablet presses from the perspective of customers, and attaches great importance to the dust problem in the production process of tablet presses. Xianghe Pharmaceutical believes that this is a primary problem to be solved. The tablet press market has reached a new level, and the business of import and export presses is also good. For the development of Chinese enterprises, it is also a problem and an opportunity!
Speed ​​is the primary basis for choice
The key to the tablet press is the choice of speed, which has a direct impact on the machine's service life, tablet weight and tablet quality. Due to the nature of the particles, viscosity, water content, particle size distribution and particle size, the pressure is different, so it cannot be determined uniformly. It can only be determined according to the actual situation and the experience of technicians. However, in general, if the mineral, plant fiber content, large diameter, and poor viscosity of the material are suppressed, it is preferable to use a low pressure tablet. The high speed of zui generally does not exceed 25 rpm. The tablet press presses various granular raw materials into discs, which are suitable for laboratory trial production or small batch production of various tablets, sugar tablets, calcium tablets, shaped tablets and the like. It is a small bench-top electric (manual) continuous tableting machine. The machine is equipped with a die, the filling depth of the material and the thickness of the tablet can be adjusted. Various shapes of molds are available upon request. The tablet press is another element of film formation. The performance of its specifications, the mechanical condition of the equipment during operation and certain important parts of the tablet press, such as the degree of wear of the die, directly affect the quality of the tablet.
See the pressure from the specification model
From the specification and model of the tablet press, the rotary tablet press has a higher pressure and uniformity than the impact tablet press, and the splitting phenomenon is easy to control. Due to the fixed bucket, the machine vibration is small, the particle stratification is less, and the weight is accurate and stable. However, the rotary tablet press has a variety of models, single rail and double rail. When there are cracks, loose pieces and different weights in production, it is necessary to consider the speed of the double-track tablet press, and the pressing time of the particles is shorter than that of the single-track type, which is prone to cracks and loose pieces. At this point, you should pay attention to increase the pressure and slow down the speed. In addition, when the difference in sheet weight is found during the tableting process of the two-track tablet press, the sheet weight adjuster and the pressure regulator of the double-sided rail should be adjusted separately. It is not possible to separately agree on the technical parameters of the track piece weight regulator and the pressure regulator, but the actual adjustment data of each track shall prevail.
Tablet press quality requirements
The tablet press meets the quality requirements. When the pellets are suitable for flowability and compressibility, there are also cases of cracks, loose pieces, adhesive sheets, slow disintegration, difference in sheet weight, surface spots, and the like. In case of cracks or disc weight differences, the speed should be slowed down. The pressure should be adjusted due to excessive pressure, which causes slugs and sluggish disintegration. For loose pieces caused by insufficient pressure, just increase the pressure. Due to the different heights of the loader device, the speed of adding the particles is different and the feeder is clogged, which affects the weight of the tablet, causing the difference. It should be stopped and checked according to the specific situation. During the tableting process of the tableting machine, when the film with sticky and surface spots is found, it should be considered whether or not the lubricating oil scale is caused by the upper punching of the tableting machine. The measure is to wipe off the oil and add a rubber cap. For particles with poor fluidity and easy to cause disc weight difference, 2 to 3 large rubber caps can be attached to the upper punch to impact the lower hopper to help flow, and the sticking to the abnormal heat of the machine needs to be overhauled. The tablet press die is an important part of the zui in the tablet press, and is often the part of the tablet that is particularly prone to problems. If the punch does not match the die ring, or the punch is curled inward, and the pressure is generated on the tablet when the tablet is pressed, causing the difference between the split piece, the loose piece and the piece weight, the die should be replaced in time, because the punch length is not uniform. The difference between the pieces of pine and the weight of the pieces should be adjusted as soon as possible. In the case of a rough surface of the punch or a film on the punch that is too deep into a sticky knot, in addition to wiping with oil yarn, it may be treated with a small amount of liquid paraffin.
Clean or not directly related to operation
The cleaning of the tablet press has a direct meaning for the normal operation of the equipment. The accumulation of fine powder can cause difficulties, and the punch and die ring are directly in contact with the drug, and the zui easy-to-plug powder is affected. When the clearance is not clean, it not only causes pollution, but also the source of the difference in color, adhesion and weight of the tablet. One of the main reasons for the contamination of the tableting machine is that the design of the lubrication system is unreasonable. The specificity of the pharmaceutical equipment is not fully considered. The lubrication of the equipment is mostly based on liquid lubricants, and the sealing is not good, which often causes drug contamination. Equipment manufacturers can consider adding grease timing lubrication devices to the tablet press or adopting a reliable sealing method to reduce or eliminate contamination of the lubricant by the lubricant. Another major source of pollution is the poor sealing of the feeder and the rotating platform, causing dust pollution.
