Developments in filling technology have come a long way. Innovations in single-use systems, multi-function design and machine flexibility have contributed to equipment design. And regulatory compliance and serialization concerns have also impacted machine innovation. Despite these advances, the methods used for liquid filling are still basically the same. The main consideration is what pump type is best suited for your application.
A good equipment manufacturer will have resources to help you determine which filling equipment is appropriate for your project. Depending upon your product, production speeds, and space conditions your manufacturer will ideally provide you with machinery that is tailored to your needs.
Time pressure filling is accomplished by controlling the flow of the product through the tubing. The product stays in the manifold that feeds the tubes. A computer calculates the product flow time needed based upon manifold pressure, nozzle size and target fill volume.
Piston fillers are ideally suited for filling a diverse range of products. These fillers are ruggedly designed yet precision built for long trouble-free operation. Product viscosities may range from 1 to 100,000 centipoises and above.
With peristaltic pump fillers, nothing but the tube touches the fluid, eliminating the risk of the pump contaminating the fluid or the fluid contaminating the pump. The complete closure of the hose, which is squeezed between a shoe and the track, gives the pump its positive displacement action preventing backflow and eliminating the need for check valves when the pump is not running.
Diaphragm pump fillers are appropriate for corrosive chemicals, abrasive materials and delicate liquids (blood, insulin, and plasma). This completely enclosed system eliminates air bubbles on small fills and features accurate repeat fills.
For vacuum powder filling, a totally enclosed system removes the possibility of product contamination. On Cozzoli’s powder filler, fill volume of each piston can be independently adjusted during operation. Two to sixteen fill stations are available. Multiple dose fills are made possible by simply setting the microprocessor. Product loss due to dusting is virtually eliminated.
