Current enterprise standard of granularity of High Shear Mixer, using dextrin (1): icing sugar (2): corn starch (3), starch paste with 10% binder, after granulation, the granule size should meet “the mass of granules and powder larger than 2mm and less than 0.18mm should not be more than 25% of total granules mass”.
According to the current enterprise standard formula of materials and binder, the experiment is planning to use dextrin (1): icing sugar (2): corn starch (3), starch paste with 10% binder on Canaan LHSZ25 High Shear Mixer. The mass of expected granules and powder greater than 2mm and less than 0.18mm (larger than 10 mesh and smaller than 80 mesh) should account for 10% to 15% of total granules mass, so as to support the improvement of enterprise standard to “the mass of granules and powder larger than 2mm and less than 0.18mm should not be more than 20% of total granules mass”.
◢ Equipment and screen mesh that used ◣
High Shear Mixer, with Mill
Needed binder for weighing
Electronic counting scale (precision display 1g)
Xiamen Balance Electronics Technology Co., Ltd
For granule size detection
◢ Material formula that used◣
10% Starch paste
Based on actual dosage
Planning to carry out multiple process explorations with the same formula until the most ideal granularity distribution data is obtained.
◢ Planned Steps ◣
Multiple preparation for use
Take the materials according to formula
Charge the material into High Shear Mixer for mixing uniformly
The granulation time is depend on the state of the soft material after binder charging
The wet granules are dried by setting the air inlet frequency and temperature of fluid-bed granulator.
Screen with 10 mesh and 80 mesh
After exploring wet granulation process for many times, the better ideal granularity distribution data than expected was obtained.
Moisture content (%)
10-80 mesh (g)
10-80 mesh (%)
<80 mesh (g)
<80 mesh (%)
After analyzing and summarizing the process-explored granules size data, the proportion of wet granules below 80meshes in all dry granules is 5.86%. Therefore, based on the result of this process exploration, in the enterprise standard of Canaan’s High Shear Mixer, the granularity standard can improve to “the mass of granules and powder larger than 2mm and less than 0.18mm should not be more than 20% of total granules mass”.
