Process for making shearform matrix
First Claim
Patent Images
1. A process for making a shearform matrix comprising:
- a) controlledly increasing the temperature of a feedstock which includes a solid non-solubilized carrier material capable of undergoing internal flow in the absence of dissolution to a point where said carrier material will undergo internal flow with the application of disruptive fluid shear force;
b) ejecting said heated feedstock resulting from step (a) as a coherent stream under pressure from at least one orifice; and
c) then subjecting said coherent stream of feedstock to a disruptive fluid shear force which separates said coherent stream of feedstock into multiple discrete and discontinuous parts and transforms the morphology of said feedstock into said shearform matrix.

Abstract
The present invention is a unique process and apparatus for making a new matrix material called a shearform matrix which results in transformation of the morphology of a feedstock. The process is characterized by increasing the temperature of a nonsolubilized feedstock carrier to a point where it will undergo internal flow, followed by ejecting a stream of the feedstock and then subjecting it to disruptive fluid shear force which separates it into separate parts or masses which have a transformed morphology. The shearform matrix may include other ingredients such as oleaginous material and actives.

17. An apparatus for making a shearform matrix comprising:
-
means for advancing, and controlledly increasing the temperature of a feedstock which includes a solid non-solubilized carrier material and applied pressure on said solid non-solubilized carrier material to the point where said carrier undergoes internal flow and is simultaneously advanced for ejection; means for ejecting said feedstock as a coherent stream for shearing said feedstock to provide said shearform matrix, said means for ejecting in a fluid communication with said means for increasing the temperature and pressure and arranged to receive said feedstock material during said internal flow condition; and means for disruptively shearing said feedstock fixed proximally to said means for ejection and disposed for effecting shear of said coherent stream of feedstock during said internal flow condition into multiple discrete and discontinuous masses whereby said feedstock material is transformed to said shearform matrix. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
