Then enter the mixing and tabletting next procedure.

[0003] The traditional boiling drying machine has two problems when drying materials:

[0004] 1. Because the state and moisture value of material drying cannot be detected in time and accurately, often rely on the experience of the operator to judge. This will often cause the final moisture of material to deviate, thereby affecting the quality of the medicine. And for the sake of safety, the drying time is usually extended, which will greatly increase the loss of fan electric energy and steam heat energy, which is not conducive to reducing production cost.

[0005] 2. Because the traditional drying method has no scientific and effective on-line detection means, in order to ensure that the drying moisture data meets the standard, the drying time is often extended. The impact and friction caused by the long time fluidization boiling of the dried granules will lead to the increase of fine powder content. In turn, it leads to the decrease of qualified granule yield, which is one of the reasons for the decrease of production efficiency. INVENTION CONTENTS
