What is the working principle of the medicinal wet granulator?

March 18, 2022

The medicinal wet granulator comprises an extrusion box, the right side of the extrusion box is sleeved with a granulation mechanism, the right side of the top of the extrusion box is fixedly connected with a storage box, the left side of the storage box is fixedly connected with a mixing box, the left side of the inner cavity of the storage box is fixedly connected with a feeding bucket, the left side of the top of the storage box is fixedly connected with a motor, and the bottom of the output end of the motor is fixedly connected with a rotating rod. By setting the extrusion box, granulation mechanism, storage box, mixing box, conveying bucket, motor, rotating rod, spiral conveying blade, feed inlet, discharge pipe, two motors, two rotating rods, mixing rod, conveying pipe, valve, three motors, three rotating rods and the second spiral conveying blade, the problem of low granulation efficiency of the existing wet granulation mechanism for pharmacy is solved.

 

However, in the process of wet granulation, the defect of pipeline blockage often occurs when the granular drugs are discharged from the discharge pipe of the wet granulation machine. The specific reason is that the drug particles prepared by the wet granulation machine are not fully dried, the drug particles are viscous and have poor fluidity. In the process of discharging drugs, the drug particles are often blocked at the discharge end of the discharge pipe, Unable to complete the timely discharge and the technical problems of material blanking and dredging discharge are not publicly solved in the prior art.

 

In the actual production process, the conventional method is often assisted by the operator manually. Knock the discharge pipe of the wet granulator and assist the drug blanking through vibration. The disadvantage of this method is that because the drugs often have pungent smell, the operators often need to tolerate the pungent smell of the drugs by using manual auxiliary discharge, which is not conducive to the health of the operators. At the same time, manual discharge is easy to pollute materials with pollutants carried by operators' hands, and drugs are threatened by pollution.
