The pharmaceutical centrifuge has the characteristics of good adaptability, high degree of automation, stable operation, strong craft, good corrosion resistance, good operating environment, reliable safety protection device, beautiful appearance and so on. The centrifugal machine used in the refining process, such as medicine, is generally low-speed centrifuge, rotating speed in 4000 to below, processing volume, in order to meet the GMP norms and requirements in the production of drugs, generally use flat-plate stainless steel materials.
There are many types of medical centrifuges.
Separate purposes can be divided into: laboratory medicine centrifuges and industrial medicine centrifuges.
According to the structure can be divided: bench medicine centrifuge and floor-based medicine centrifuges.
According to the temperature control can be divided: frozen medicine centrifuge and temperature medicine centrifuge.
According to the separation components can be divided: solid liquid separation centrifuge and pharmaceutical liquid separation centrifuge.
Can be divided by capacity: micro-medicine centrifuge, small-capacity medicine centrifuge and large-capacity medicine centrifuge.
From the functional aspect, the pharmaceutical centrifuge has the following advantages:
1, the material adaptability, choose the appropriate filtration medium, can separate millimeter-level fine particles, can also be used as the dehydration of items, through the washing tubes can be done to clean the goods.
2, the artificial upper unloading type structure is simple, easy to install, low cost, easy to operate, can maintain the product's grain shape.
3, the machine adopts advanced elastic support structure, can reduce the vibration caused by uneven load, the machine runs smoothly.
4, the entire high-speed operation of the structure, concentrated in a closed shell, can be sealed to avoid contamination of materials.
For low-speed centrifuge, due to the strict norms of the pharmaceutical industry, it basically adopts flat-plate airtight type, in order to reduce the possible pollution or damage or improve hygiene, and the material contact part adopts stainless steel material or whole adopts stainless steel material, no sanitary dead corners, clean and easy to use, this type of centrifuge basically all over the entire pharmaceutical industry, coupled with the blood separation of about 3000 rotating small centrifuges, constitute the entire low-speed industrial centrifuge system, but also infiltrated the biomedical associated with other industries. This type of centrifuge must conform to the national GMP standard can be used.
High speed Centrifuge is the use of DC brushless motor, maintenance-free; microcomputer control, can preselection rotational speed, time, centrifugal force, LCD display, easy to operate; 10 kinds of lifting rate to choose, can quickly start, fast downtime; stainless steel containers room, electronic locks, alarm function, a variety of protection, safe and reliable.
The technology of such centrifuges is simpler, the general multi-purpose area belt centrifuge, the district belt centrifuge is according to the sample solution density, the gradient carries the cell, the virus, the DNA molecule separates and collects, its addition sample and the inferior sample all adopts the continuous way, in the widespread use in the production craft, now also the large quantity applies to the lab equipment.
In the pharmaceutical industry, because of the production quality and production safety requirements more stringent, so the production of centrifuges and other pharmaceutical products in the field of raw materials production process of the main equipment is also very high requirements. In addition to the centrifuge to maintain its own separation characteristics, but also need to meet the pharmaceutical field of relevant norms, standards. The medicinal centrifuge needs more from the point of view of satisfying the requirement of pharmaceutical production process, considering the material, structure, input and output mode, safety, labor intensity, control, cleaning or disinfection and so on.
The medicinal centrifuge has the washing and sterilizing requirements for the batch and the variety of the production, preventing all kinds of pollution sources and avoiding contamination again. The medicinal centrifuge needs to work on the program automatic control, the human-machine isolation operation, easy cleaning, disinfection and sterilization structure, on-line analysis and the research and improvement of different character material separation methods, improving function, control and aseptic operation level.
Because of the medical field of centrifugal confidential and medicine, so the surface of the centrifuge equipment must be clean, flat, no dead corners, so must ensure that the centrifuge's sharp corners, corners, welds in the production process to smooth over the transition round corners. Because of the need to contact with medicines, centrifuges need to resist corrosion, not chemically altered or adsorbed drugs.
With the development of centrifuge, the related technology of centrifuge has been promoted. But the drug machine industry can not be complacent, must continue to develop, in the national policy support, centrifuge enterprises to continue efforts to promote centrifuges in the pharmaceutical industry more widely used.
