Abstract:
With a mashing process, the mash is fed to the filter material of a dynamic cross-flow filtration system, wort is withdrawn from the side-stream side of the filter material and thickened remainder is withdrawn from the feed side of the filter material.
Abstract:
A vibratory separation systems, membrane modules, and filter elements, as well as the methods for making filter elements, which embody the various aspects of the invention provide many advantaged over conventional vibratory separation systems and components. In accordance with one aspect of the invention, a filter elements includes a support plate having at least one through hole, a separation medium mounted on the support plate, and a sealing member disposed at the hole to prevent fluid from flowing from the hole between the support plate and the separation medium. Filter elements embodying this aspect of the present invention are highly reliable and effective in preventing leakage between the separation media and the support plates. And if the bounding layers are present in the vicinity of the through holes of the support plates, the sealing member can fill the interstices in the bonding layers, preventing leakage through the bonding layers between the separation media and the support plates.
Abstract:
A method for bonding a porous medium (29) to the surface of a solid substrate (41) is disclosed. The method comprises positioning a dry porous medium (29) near a dry surface of a substrate (41) and impregnating the porous medium with a bonding composition by opening a valve (47) and allowing the bonding composition to pass through passageway (33) to groove (31). The impregnated porous medium (29) is maintained near the substrate surface (41) until the substrate surface is at least slightly dissolved in the bonding composition without dissolving the porous medium (29). At least a portion of the bonding composition is flushed through the impregnated porous medium (29) towards the substrate (41) and subsequently away from the surface of the substrate by opening of valve (44) at the adaptor (42) to a vacuum source (45). The bonding composition is then evaporated at a controlled rate from the substrate (41) and the porous medium (29).
Abstract:
The present invention provides a supported fibrous web assembly comprising a support material adhered to a nonwoven web of multicomponent fibers comprising a first polymer and a second polymer such that the second polymer is present on at least a portion of the surface of the multicomponent fibers and has a softening temperature below the softening temperatures of the first polymer and the support material, wherein the supported fibrous web assembly has a water flow rate of at least about 20% of the water flow rate of the nonwoven web of multicomponent fibers alone. The present inventive supported fibrous web assembly can further comprise a second fibrous web, which is adhered to the nonwoven web of multicomponent fibers such that the nonwoven web of multicomponent fibers is positioned between the second fibrous web and the support material, and wherein the supported fibrous web assembly has a water flow rate of at least about 20% of the water flow rate of the second fibrous web alone. The present invention also provides a filter element comprising a housing and such a supported fibrous web assembly, as well as a method of preparing such a supported fibrous web assembly and methods of using such a supported fibrous web assembly.
Abstract:
A method for treating raw milk to produce treated milk having a lower bacterial content than the raw milk. The milk is homogenized and within about 5 minutes from the homogenization, subjected to dynamic microfiltration, to yield a filtrate which has a lower bacterial content than the initial raw milk. The resultant milk can be sterile, free from Bacillus cereus bacteria that usually causes degradation of milk quality during refrigerated storage. The milk can be shipped even under non-refrigerated conditions without spoilage, for extended periods of time.
