What improvements have been made to the structure of the high-speed rotary tablet press

In recent years, many tablet production enterprises have gradually approved the high-speed rotary tablet press from trial to gradual approval, and now they are likely to replace the high-speed rotary tablet press. To explore the reasons, I believe that anyone who has a general understanding of high-speed rotary tablet presses will say“The advantages are small chip difference, high efficiency, energy saving, less land occupation, and high degree of informatization”. Taking our company's high-speed rotary tablet press as an example, the manufacturer of the tablet press makes a summary analysis from 6 aspects around the cost performance, for the user's reference when selecting models. (1) High output output. For tablet presses with the same tablet diameter and similar number of dies, the output of the high-speed rotary tablet press is 4 to 5 times that of the low-speed rotary tablet press. That is to say, to complete the same output in the same time is the quantitative relationship between the high-speed rotary tablet press and 4 to 5 low-speed rotary tablet presses. (2) The product yield is high. We know that the material loss in the tablet production process is mainly concentrated in the initial parameter setting and adjustment of the test tablet and the load reduction protection before shutdown. For the normal production of the high-speed rotary tablet press, the batch utilization rate is above 99%. However, it is difficult for the low-speed rotary tablet press to reach this target, especially when multiple devices are selected, and the chance of wasting materials will be reduced by a few. double or double. (3) The direct cost of equipment is basically the same. The price of a domestic high-speed rotary tablet press may be able to buy 4 to 5 low-speed rotary tablet presses, but the low-speed rotary tablet press must be equipped with multiple sets of auxiliary equipment, and the comprehensive calculation will be almost the same. (4) Remarkable energy saving and consumption reduction. A high-speed rotary tablet press requires a purification pharmaceutical cleanroom of about 20m2, while a low-speed rotary tablet press requires a total of 40-60m2. Due to the increase of the area of ​​the purification area, the amount of purified air required for the production process also increases proportionally. For example, based on the indoor height of 3.5m, production of 8h/d, and ventilation of 15 times/h, the high-speed rotary tablet press and the low-speed rotary tablet press The amount of purified air required by the tablet press per day is 8400m3 and 16800-25200m3 respectively. Over time, the difference in costs cannot be underestimated. In addition, in the process of tablet pressing, in addition to the main tablet machine, each main machine needs to be equipped with auxiliary pharma machinery such as lifting feeder, vacuum cleaner, sieving machine and metal detector. Therefore, the overall energy consumption is as staggering as the purification system. (5) Labor costs are greatly reduced. Domestic pharmaceutical companies generally assign 1 to 2 operators to each tablet press. For the high-speed rotary tablet press, due to the automatic control of tablet quality and other functions, even one person can operate multiple devices. (6) management costs are greatly reduced. Routine cleaning and maintenance of tablet presses*. In addition to labor costs, a large number of consumables are required, including drinking water, purified water, cleaning agents, disinfectants, and anti-rust oil for protecting dies, etc. Obviously, the advantages of one set of equipment over multiple sets of equipment are self-evident. Of course, there is still a fly in the ointment when choosing a high-speed rotary tablet press——Faced with production schedule risk. Once a sudden failure occurs and stops production, it will have a huge impact on the output; while the risk of low-speed machines with relatively low output is much smaller. Therefore, when selecting the type of the tablet press manufacturer, the user must proceed from the actual needs of the pharmaceutical factory, and should also focus on the functional perfection, operation stability, safety and reliability of the high-speed machine, and the convenience of operation, cleaning and maintenance of the pharma machinery tablet press. and service timeliness to comprehensively weigh.
