GMP in pharmaceutical processing and its implications for centrifuges

Good Manufacturing Practice (GMP) regulations were introduced as a means to ensure that a given product is processed reliably, repeatedly, consistently, safely and to a high quality. In the pharmaceutical processing industry GMP is an essential part of the production process. Centrifuges are a major processing tool used in this industry. In the following article, Nigel Day discusses the implications that GMP has had on the design, manufacture and operation of industrial centrifuges, with a particular focus on horizontal peeler type machines.

Cleaning process waste water with pressure centrifuges

Conclusions Pressure centrifuges of diameter 25–50 mm can be used to clean process waste water contaminated with fine fireclay, magnesite, chrome-magnesite, or fireclay-clay mixtures; the centrifuges may be combined into blocks.Pressure centrifuges may be used to clean the process water used in wet air-cleaning systems to free the air from fireclay, magnesite, and clay dusts.Translated from Ogneupory, No. 7, pp. 19–24, July, 1968.

Processing of dispersions containing fine particles or biological products in tubular bowl centrifuges

The demand for instruments that are suitable for the separation of fine particles and biological cells is steadily increasing. Various innovative particles have already implemented in bulk products and many others are close to commercial availability. Tubular bowl centrifuges offer high centrifugal forces at reasonable throughputs. There is a high potential for the optimisation of existing processes and in the design of new tubular centrifuges especially for the separation of nanoscale materials. The separation of fine particulates and biological cells in a semibatch tubular bowl centrifuge at high rotational speeds is described in this work. Furthermore, the influence of the sediment on the process outcome and possibilities to enhance the separation efficiency were investigated. A boundary layer flow was indirectly detected. Structures inside the rotor of the centrifuge cause defined liquid flow patterns, which influence the separation efficiency. A comparison of the separation behaviour with an unimpaired flow and the redirected flow yielded conclusions about the actual flow patterns.     

离心机转鼓整体三维有限元分析与强度计算

转鼓是离心机的关键部件,其设计正朝着转速更高,直径更大的方向发展,因此鼓壁鼓底等零部件间的相互影响和作用越来越大。这类结构的强度问题更为突出,对强度分析的要求也越来越高。为此,本文提出用三维立体单元对过滤式离心机整个转鼓进行分析。由于此方法对转鼓全部采用三维立体单元进行网格划分,因而可以模拟复杂的局部结构和边界条件。本文对某国产卧式刮刀卸料离心机大直径转鼓的有限元计算结果表明,在转鼓底和拦液板中的应力水平较低;在转筒体中应力水平较高,在开孔周围存在着应力集中现象,最大虚拟弹性应力值远大于材料的屈服限。最后,对该离心机转进行了强度评定
