Tablet press selection basis According to the production process and quality requirements of drugs, the selection of tablet press is mainly from the following aspects: (1) According to the characteristics of powder and particle, choose the appropriate tablet press (mainly Chinese medicine or western medicine, the composition proportion of raw and auxiliary materials, etc.); (2) Determine the output of equipment according to capacity and reserved capacity; (3) select the appropriate charging system according to the existing process; (4) According to the production record and deviation, equipment maintenance frequency and equipment control points in the production process of the product in the past; (5) the operation is convenient, reliable, there is a necessary adjustment device. Such as mechanical regulating device, filling regulating device, pressure regulating device, speed regulating device, sheet thickness regulating device, etc. (6) The design of the tablet pr

Wired technology of tablet press A tablet press can be connected to a production line, and both German and British tablets have this capability. It has the function of start, end and speed adjustment. Using this option, it can be reliably and automatically connected with other equipment in the production line, such as screen, vacuum, testing, conveying, bucket, etc., to complete the pressing task of the tablet simultaneously. At the same time, different monitoring methods are used on the external equipment to provide high safety and reliability performance. Use an online detector to remove burrs, frills, and dust from pressed tablets. The suction monitoring function is to use the flow monitoring instrument to regularly detect the suction pressure in the specified position of the suction pipe. Continually compare the set value with the measured value. If the detector does not detect the suction pressure (no flow) in the suction tube within 10s, the tablet press will send out a fault

Tablet press customization requirements In the customized orders of users, the diversified requirements of the structure are mainly reflected in the following aspects: On the way of film, there are requirements for single-sided film, double-sided film, there are requirements for both single-sided film and double-sided film. It is necessary to design and transform the structure of the tablet press to meet different requirements. In terms of protection, there are requirements for broken punch protection structure, and there are requirements for automatic power protection when opening the tablet chamber door. The fault-punch protection structure refers to that when the punch rod breaks suddenly in an accident, the fault-punch protection system responds quickly and the equipment stops automatically immediately, so as to prevent the occurrence of safety accidents and eliminate the hidden danger in the bud. Automatic power off protection when opening the tablet chamber door means

Tablet classification of tablet press For tablet manufacturers, the product is no longer a single round tablet, but has a variety of diversified requirements. (1) From the shape to the points, there are ring, square, trapezoid, oval, triangle, spherical, petal shape, deep concave, shallow concave and a series of various requirements. To achieve these tablet products to suppress, the punching die need customized according to user's tablet products, most of the non-standard punching die, habits will suppress square, trapezoid, triangle, petals noncircular tablet punching die is called alien dies, this kind of punch punch needs to be configured on the directional keys, turret punch holes need machining keyway and punch to cooperate to complete the tablet for suppression. (2) from the color points, there are monochrome, two-color, etc. Monochrome sheet is pressed with one kind of material, two-color sheet needs two kinds of materials (that is, two kinds of materials pressed into a

Counting and scraping of tablet press Automatic tablet counting is done using sensors. A toothed counting plate is fixed on the outside of a pulley of the transmission part, and the number of teeth corresponds to the number of punches of the rotary table of the tablet press. A fixed sensor below the tooth transmits electrical signals to the control system. Thus, the number of teeth turned by the counting disk represents the number of punches pressed on the rotary disk, that is, the number of pieces pressed out. According to the order of the teeth, the control system can identify the punch number. For tablets of the same specification, the weight, hardness and disintegration of the tablets are adjusted to meet the requirements by hand at the beginning of the production of the tablet press, and then transferred to the computer-controlled state. The thickness and the weight of the tablets are the same. If the particles in the die are too loose or too dense, it indicates that the she

The work of double layer tablet press The main work of the double-layer tablet press includes the first layer of material filling, quantifying and prepressing, and the second layer of material filling, quantifying, main pressing, stripping and other procedures. Driven by the turntable, the upper and lower punching dies move clockwise along the upper and lower rail guide respectively. When the punch moves to the filling section of the first layer, the upper punch moves upward to bypass a layer of material feeder. At the same time. Down by the downward rail cant move down, at this point, the upper surface of the punch and die forming a cavity, powder materials after feeder concone fill the mould cavity, the punch through down the downward track low form excessive filling (pack), tablet press punch with the turntable continue movement, down after filling the rail gradually upward movement. The excess powder particles in the inner hole of the medium mold are pushed out into the quantita

Dust-collecting device of double layer tablet press The dust suction device of common monochrome tablet press generally adopts single or double layer powder suction nozzle, and the dust generated during the pressing is inhaled by the dust suction machine. Suppression of double-layer tablets either feeder feeding way, by scraping powder plate out of the overflow particle can guarantee the uniformity of filling, but the tiny dust will also exist in turntable model plane, especially in the mold on the plane and die in the turntable on plane between 0. 01, 0. 05 mm clearance of fine dust, equipment running can cause mixed color phenomenon for a long time, only the first layer material after preloading, two layers of material master pressure molding position behind the increase in special vacuum cleaner, the fine dust in the plane of the die in turntable by suction machine suction, to ensure long-term continuous operation. In order to improve the recovery rate of double piece of materia

What are the advantages of high speed rotary tablet press? In recent years, many tablet manufacturers have moved from the experimental phase to the gradual adoption of high-speed rotary tablet presses. When investigating the reasons, I believe that people with a general understanding of high-speed rotary tablet presses will say: "The advantages are small differences between tablets, high efficiency, energy saving, space saving and high information content." For example, our high-speed rotary tablet press, centering on the price, quality and cost performance from six aspects of analysis, for the choice of tablet press provides a reference. (1) High output. The output of disk presses and similar presses of the same diameter is four to five times that of low-speed rotary presses. That is to say, the same production at the same time, is the number of high-speed rotary presses and 4-5 low-speed rotary presses in proportion. (2) High product yield. We know that material losses in th

The production problem of domestic tablet press There is dust problem during the pressing process. The solution to the powder problem in the pressing process is discussed below. (1) Dust source analysis. At present, the dust produced by high-speed rotary machines and household screening machines in the production process is generally extracted through the negative pressure provided by special vacuum cleaners. However, due to the insufficient technical level and sensitivity at present, the sealing effect of the equipment itself is not good, and some dust still leaks into the purification zone. In addition, particles produced during the transport of substances or tablets may be released directly from the associated joints into the purified area. (2) Actual purification index. At present, domestic GMP purification level mainly focuses on static indicators. In this case, the powder produced during the stamping process is usually ignored. In Europe, the United States, Japan and oth

How to operate a high speed tablet press? 1. Before use, repeatedly check whether there are edges, cracks, deformation, insufficient compaction and other conditions of the press die quality, and check whether the equipment is complete and whether the work is normal. 2. Check whether the dust in the granule raw materials is dry. The dust content in the granule should not exceed one tenth. If not meet the requirements, please do not press hard, otherwise it will affect the normal operation and service life of the machine, and cause the loss of raw materials. 3. The first command control of the pressure regulator, the powder into the bucket, turn the test by hand wheel, regulating drug packing at the same time, gradually increase the pressure gain weight into need to finished product, and then start the engine, open the clutch and the formal operation, the production process should be regularly checking the quality of the drug, if not qualified, adjustment, normal operation if qu
