Analysis of the structure and application requirements of the two-color tablet press
Two-color tablet press presses two different materials into one tablet. The two materials are separated from each other and have different colors. The compression of the two-color tablet is mainly based on the design and modification of the lower guide rail. Two fillings and one slice.
The main situations in the process of pressing two-color tablets with a two-color tablet press are: (1) The content of the two materials on the same tablet does not meet the requirements. This is mainly because the filling adjustment system has not been adjusted, and the content of one material can be adjusted first. Then adjust the content of the other material; (2) The two materials of the extruded tablet have splitting phenomenon, the hardness is uneven, one material is harder, and the other is softer, the main reasons are: 1) the material Reasons, density, drying humidity, poor adjustment of the uniformity of the two materials, and then adjust the materials before pressing; 2) Improper adjustment of the pressure of the two materials. The principle of forming a two-color film is to fill it twice, once, if the pressure is not adjusted after the first filling, the hardness of the second half will become hard or soft. After the second fill, the pressure is set for the complete tablet, so the pressure adjustment determines how well the tablet is formed and bonded.
Two-color tablet presses usually need to be equipped with two vacuum cleaners, which can separate the two materials for powder absorption and recovery. If the user has precise requirements for the composition of the two materials, the tablet press machine can be configured to take tablets from one material separately and perform precise measurements to determine its content.
