Granted: 1991-01-29
Abstract: SYSTEM AND METHOD FOR PRODUCING             HIGH QUALITY SULFUR CONCRETE               ABSTRACT OF THE DISCLOSURE      A high quality modified sulfur concrete product is produced by blending together in a blending zone,  a first stream comprising an aggregate material and suf-ficient heat  energy to  fluidize  a  sulfur-containing cement stream on conducting a subsequent stirring step, and a  second  stream  comprising  a  sulfur  containing cement stream, typically in the form of modified sul-fur-containing cement.  Preferably, a chemically-resis-tant  fines  material  is  incorporated  into  the  first stream, although it can also be added directly to the stirring means.  Blending is conducted without requir-ing  any  auxiliary mechanical  mixing as  specifically required  in  conventional  sulfur  concrete  processes.          Typically,  the blending step comprises impinging the first and second streams one with each other in the blending zone for in situ dispersing of the respective streams.   The dispersed-blended stream is transferred from the blending zone to a stirring means, where it is collected.   Since the first and second streams have already been blended and dispersed, all that remains to be done is stirring.

A  liquid dairy  product  is  heated to a temperature of at least 160°F for a time not in excess of 30 minutes, whereby the  indigenous  dairy  protein  and  ash therein are  at least  partially denatured.  The  denatured  liquid  dairy product  is then  cooled to a temperature of less than about 50°F. The cooled liquid dairy product is subjected to  pressurized  carbon  dioxide  at  sufficient  pressures and for a sufficient time such that the taste and mouth feel of the carbonated dairy product is no longer that of the  uncarbonated dairy product.  The carbonation is carried  out  until  there  are at  least  1.5  volumes  of carbon  dioxide  dissolved  in the  dairy  product.  The product is then packaged in closed containers capable of substantially retaining the said degree of carbonation. The amount and extent of the heat denatured indigenous protein and ash in the dairy product is sufficient that the carbonated dairy product is buffered to a pH of at least  4.0  and the  carbonated  dairy  product is highly carbonated but not destabilized.
