The present invention is related to method for irradiating bulk material, particularly for treatment of food products such as grain, characterized in that in the case of a failure of said irradiation, the untreated bulk material is separated from the treated material and subsequently transported back towards the beginning of the process, in order to be treated. The invention allows to avoid re-treatment of large quantities of material, and provides a clear separation between contaminated and uncontaminated parts of the installation.

Method and installation for irradiating bulk material

Hollow fiber membrane modules are manufactured by weaving hollow fiber membranes into a web while the fibers still contain a residual amount of the organic liquids used in the extrusion of the fibers. The web once formed is then passed through a final solvent extraction stage, followed by drying and heating to fix the final form and permeation characteristics of the membranes, and finally rolling the web into a bundle which forms the interior of the module. The hollow fibers are woven as fill in the web.
