Post Bin Blender

HTD post bin blender is extensively used for mixing a dry powder with dry powder or dry powder with grain in the process of diversified solid preparation production in the pharmaceutical industry. This mixer can be equipped with hoppers of various specifications.

It is suitable for mixing pharmaceuticals of multiple varieties and different batches according to the technological requirements in large and medium-sized pharmaceutical enterprises, so it can achieve multiple purposes in one machine.


Working Principle

When running the machine, push the mixing hopper into a rotary arm and tighten the nuts, then start the control system and lift the hopper to the mixing height. Then, the control system starts mixing automatically according to the setting time and rotation speed, etc. When finish mixing, the material fixed in a horizontal position and the hopper downwards to the ground automatically. After that, the whole machine stop and print process data. Finally, unfasten the locking nuts of the rotary arm and move the hopper out, and transfer it to the next process. As the symmetrical axes of hopper and the rotating center line of rotating arm form an included angle, materials with different constituents are strenuously rolling over in the closed hopper and producing high shear to achieve the best effect of mixing.

Main Features:
  1. It is a high-tech product that integrates machinery, electronics, and hydraulics into one body. It employs hydraulic lifting and driving, and PLC control, which is easy to operate and convenient to adjust technological parameters.
  2. The control system is highly sensitive, and the whole machine is compact in structure, stable, and reliable in running.
  3. A single machine can be equipped with hoppers of various specifications. The materials after mixing remain in the hopper, which will be dismounted from the rotating arm and shifted directly to the next procedure, thus greatly improving the utilization efficiency of the mixer and also avoiding cross-contamination of materials. This machine completely accords with the GMP requirements.
  4. The mixing barrel can be used as a batching barrel in the upstream procedure and as a charging hopper in the downstream procedure (compressing and filling).
  5. The evenness of mixing reaches above 99%, the volume charge coefficient reaches 0.80, both the inner and outer surface of the barrel is clean and smooth without a dead corner.
  6. After mixing each batch of pharmaceuticals, the empty hopper is sent to a special cleaning room for cleaning, so as to keep the workshop clean.
