  • Publication number: 20240123657
    Abstract: Continuous compression molding machines (CCMMs) and methods of continuous compression molding a consolidated thermoplastic matrix composite material are disclosed herein. The CCMMs include a mold, a heat zone heating structure, a consolidation zone heating structure, and a stress relaxation zone heating structure. The CCMMs also include a press structure, a demold structure, and a supply structure. The methods include providing a thermoplastic matrix composite material (TMCM) that includes a thermoplastic material to a CCMM. During the providing, the methods also include heating the TMCM within a heat zone of the CCMM, cooling and consolidating the TMCM within a consolidation zone of the CCMM, relaxing stress within the TMCM within a stress relaxation zone of the CCMM, demolding the TMCM within a demold zone of the CCMM at a mold temperature that is greater than a glass transition temperature of the thermoplastic material, and periodically compressing the TMCM.

  • Publication number: 20050249848
    Abstract: The invention is directed to a process to reduce blackbone occurrence in meat. The invention is further direct to reducing blackbone discoloration in meat while maintaining higher yields and without negatively affecting the appearance of the meat. The processing steps include treating the meat, preferably by injection, with an alkaline phosphate solution; and after treating the meat with the alkaline phosphate solution, contacting the meat, preferably by dipping or spraying the meat, with hexametaphosphate in an amount effective to reduce blackbone in the meat.

  • Publication number: 20050058751
    Abstract: The invention is directed to a process for treating meat to achieve higher yield, without negatively affecting the appearance of the meat. The process comprises the steps of 1) treating the meat, preferably by injection, with a higher pH phosphate solution having a pH of above pH 6.0 and 2) after treating the meat with the higher pH phosphate solution, contacting the meat, preferably by dipping or spraying, with a lower pH solution of preferably less than about pH 5.6.
