Problems solved by technology
[0003] However, the semi-permeable membrane area of existing preparation equipment is limited, so the efficiency of separating and purifying drugs is greatly reduced, and most of the equipment is a fully enclosed structure, which is extremely inconvenient for inspection and maintenance. Reduce the working efficiency of the semi-permeable membrane

The invention relates to the technical field of pharmaceutical production devices, in particular to nifedipine controlled release tablet semi-permeable membrane preparation equipment and a preparation process thereof. The equipment comprises a main body, a supporting seat is welded to the bottom end of the main body, a communicating mechanism is arranged on the main body, a circulating mechanism is installed in the main body, and an opening and closing mechanism is connected to the main body. A cleaning mechanism is arranged at the bottom end of the opening and closing mechanism, and a desilting mechanism is arranged at the bottom end of the main body; through the arrangement of the opening and closing mechanism, the main body can be conveniently opened for daily maintenance; the opening and closing mechanism drives the cleaning mechanism, so that a dirt collecting box component on the cleaning mechanism can be detached and cleaned conveniently, and the cleaning mechanism can collect dirt better; through the arrangement of the cleaning mechanism, the permeable membrane component on the circulating mechanism can be conveniently cleaned; and the circulating mechanism is kept in an optimal working state; in addition, through arrangement of the dredging mechanism, dredging and cleaning of sediments at the bottom end of the main body are facilitated, and cleaning of the main body is facilitated.
Description
technical field [0001] The invention relates to the technical field of pharmaceutical production devices, in particular to a semi-permeable membrane preparation equipment for nifedipine controlled-release tablets and a preparation process thereof. Background technique [0002] A semi-permeable membrane is a thin film that only allows certain molecules and ions to diffuse in and out. Generally speaking, a semi-permeable membrane only allows ions and small molecular substances to pass through, while biological macromolecules cannot pass through the semi-permeable membrane freely. The size of the pores of the membrane is larger than that of ions and small molecules, but smaller than that of biological macromolecules such as protein and starch. The existing laboratory development of nifedipine controlled-release tablets is mostly prepared by semi-permeable membrane technology. [0003] However, the semi-permeable membrane area of existing preparation equipment is limited, so t...
