专利汇可以提供MANUFACTURING MATRICES专利检索,专利查询,专利分析的服务。并且The present invention is directed to a process for the manufacture of porous cellulose matrices with a defined particle size and a significantly higher porosity (i.e. pore volume) than conventional formulations, such as pellet formulations containing cellulose and binders. The process is applicable on a wide variety of substantially dry cellulose raw materials. The cellulose is mechanically treated with low adhesion to the process equipment during a controlled gradual addition of an aqueous based fluid, optionally containing a surface-active ingredient, into regular particles, which are finally dried to obtain dry porous cellulose matrices. The so obtained matrices can be used as carriers for bioactive substances in multiple-unit preparations or tablets.,下面是MANUFACTURING MATRICES专利的具体信息内容。
