Abstract
A method and irradiator apparatus used for wort sterilization by radiation for production of ethanol from sugar cane, comprising a trough-like fluid duct and a radiation source for directing radiation over the flow of a fluid conducted through the duct, and application of radiation to a fluid within an apparatus for sterilization of such fluid.
Claims2
An apparatus for sterilization of a fluid, comprising:
- a fluid duct comprising a first horizontal portion through which fluid flows from a first end to a second end;
- an inclined portion located downstream of the first horizontal portion and receiving fluid from the second end of the first horizontal portion, the fluid passing down the inclined portion and exiting at a distal end relative to the first horizontal portion;
- a second horizontal portion downstream of the inclined portion and receiving fluid from the distal end;
- and
- a gamma radiation source positioned above the inclined portion of the fluid duct;
- wherein horizontal fluid flow through the fluid duct proceeds through the first horizontal portion, the inclined portion, and the second horizontal portion generally in a single horizontal direction defined by flow from the first end to the second end of the first horizontal portion;
- and
- wherein the fluid duct conducts fluid from the first horizontal portion through the inclined portion wherein it may be sterilized by radiation to the second horizontal portion.
5 more elements
An apparatus for irradiation of a fluid, comprising:
- a plurality of fluid ducts;
- and
- a plurality of gamma radiation sources;
- wherein the gamma radiation sources direct gamma radiation over at least a portion of at least some of the plurality of fluid ducts;
- wherein horizontal fluid flow through the fluid duct proceeds through a first horizontal portion, an inclined portion, and a second horizontal portion generally in a single horizontal direction defined by flow from a first end to a second end of the first horizontal portion;
- and
- wherein at least some of the fluid ducts direct the flow of a fluid through the path of gamma radiation.
