[0040] The working mode of the present experimental example is as follows: three kinds of powder raw materials that need to be granulated are microcrystalline cellulose, lactose and corn starch, which are fed according to the ratio of 40:40:20 required by the granulation process, and are respectively sucked into the corresponding hoppers through three vacuum feeders 4. The single working time of the vacuum feeder 4 is 20 s. The powder raw materials enter the corresponding continuous feeders 6 through the first silica gel hose 5. In the continuous feeder 6, the powder raw materials are pushed by the screw of the rotating conveyor 601 of the continuous feeder 6 to flow and convey in the cavity of the continuous feeder 6. The conveying rates of the microcrystalline cellulose, lactose and corn starch are set to be 40 kg / h, 40 kg / h and 20 kg / h respectively, and the screw rotation speeds of the three continuous feeders 6 are 120 r / min, 120 r / min and 60 r / min respectively. At the same time, the weight data changing with time is measured by the weighing sensor built in the continuous feeder 6. When the conveying rate error of the three continuous feeders 6 exceeds 2%, the measured weight data is fed back to the PLC controller, and the conveying screw rotation speed of the three continuous feeders 6 is dynamically adjusted by the PLC controller to make the conveying rate error meet the process requirements. When the material in the hopper of the continuous feeder 6 is about to be conveyed, the PLC controller starts the vacuum feeder 4 to intermittently suck the powder raw materials from the external hopper into the hopper of the continuous feeder 6 until the hopper is full and stops. The powder raw materials of microcrystalline cellulose and lactose in the three continuous feeders 6 are sucked by the vacuum feeder 4 every 15 s to replenish the materials, and the replenishment time is 12 s. The powder raw material of corn starch is sucked by the vacuum feeder 4 every 20 s to replenish the materials, and the replenishment time is 12 s.

[0041] The three kinds of powder raw materials enter the conical adapter barrel 10 through the corresponding second silica gel hose 9, are combined in the conical adapter barrel 10, and are further introduced into the main machine of the continuous mixer 12 through the third silica gel hose 11 and the first feeding hopper 1201. In the main machine, the powder materials are alternately mixed by two counter-rotating screws with a rotation speed of 100 r / min. The mixing process is carried out in the flow of the materials. The mixed powder raw materials are discharged through the first discharge port into the rigid inclined discharge pipe 1202.

[0042] The mixed powder raw materials in the rigid inclined discharge pipe 1202 are detected by the mixing uniformity detection sensor 14 on the side wall of the rigid inclined discharge pipe 1202 to determine whether the mixed powder raw materials reach the mixing uniformity. The spectral integral areas of the mixed powder raw materials measured by the three near-infrared probes at a certain time are S1=1.02, S2=1.04 and S3=1.05 respectively. The uniformity error index is calculated according to the following formula.

[0043]

[0044] The error limit of the uniformity of the mixed powder raw materials is 5%, and the deviation of the uniformity of the above mixing is less than 5%, so it is determined that the three powder raw materials of microcrystalline cellulose, lactose and corn starch have been mixed to be uniform, and the mixed powder raw materials will be continuously conveyed and enter the 6 continuous wet granulator 15 through the fourth silica gel hose 13. The internal granulating assembly of the continuous wet granulator 15 is two granulating shafts rotating in the same direction, which shears and granulates the mixed powder raw materials entering, and the rotating speed of the granulating shafts is 400 r / min.

The continuous wet granulator 15 mixes and kneads the mixed powder raw materials and the povidone binder solution, and finally discharges the uniform granules from the second discharge port.

[0045] The torque sensor, temperature sensor and flow sensor built in the continuous wet granulator 15 during the granulation process can monitor the running state of the continuous wet granulator 15 and the flow and stability of the binder solution in real time and on line, so as to realize real-time and on-line control of the quality of the granulation products, realize zero error and zero defective products.

[0046] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be regarded as the protection range of the present application.
