Point-of-fill

Ignition point of filled HDPE, or HDPE-based composites, would be about the same provided that the material does not contain active flame retardants. Indeed, filled or not filled, HDPE in the material would still melt and emit flammable VOC (volatile organic compounds), which would ignite at a certain temperature point, close to that one for neat HDPE. A difference would depend mainly on the amount of HDPE in the material and the size of the sample. 

The final zone of protection is the localized protection given to point-of-fill and to manual processes conducted within the filling room. 

The whole operation of forming a sterile container, filling it, and sealing it, is conducted within one machine. The filling zone for aseptic filling is afforded localized filtered air protection. There is no intervention from personnel until after the filled presentation is sealed and automatically moved away from the point of fill. What need therefore for location within a Class 100 clean room, or for protection by the double barrier principle Support for this argument has come mainly from media fill studies conducted with machines located in Class 10,000 areas [10]. Accumulation of uncontaminated individual trials, each of several units of thousands of items to total numbers of several tens and even hundreds of thousands of items has been used to claim equivalence between form-fill-seal in Class 10,000 clean rooms with conventional double-barrier aseptic fill in Class 100 clean rooms. 

The Joanne oils are likely to have been spilled from the Judy structure. This has resulted in a decrease in wax content and maturity away from the point of filling. The Joanne oils are unlikely to have been sourced from the southwest as they have higher wax contents than the Pre-Cretaceous oils in 30/7a-8 and 30/7a-P7. 

It may not always be possible to demonstrate conformity with particular air standards at the point of fill when filling is in progress, owing to the generation of partides or droplets from the product itself. 

Precautions should be taken to ensure uniformity of suspensions at the point of fill throughout the filling process. 

This condition should be achieved throughout the room when unmanned, and recovered within a short clean up period after personnel have left. The condition should be maintained in the zone immediately surrounding the product whenever the product is exposed. (Note It is accepted that it may not always be possible to demonstrate conformity with particulate standards at the point of fill, with filling in progress, due to generation of particles or droplets from the product itself). 

Tubs and soft ice creams do not require substantial product assembly. Tubs are filled with ice cream straight from the factory freezer and then hardened. Inclusions may be added at the point of filling, using a fruit feeder. This consists of a hopper for the inclusions a means for... 

Given the laminar nature of the flow, mixing of separate vapor streams is dominated by diffusion. The mixing will be complete and uniform, when the vapors diffuse radially to the point of filling the entire flow diameter, which occurs in characteristic time Xd ...
