The granulation process of the wet mixing granulator is completed
by the two processes of mixing and granulation in the same container.
The powdery material is in a fixed cone-shaped vessel, and due to the stirring effect of the mixing slurry, the material collision is dispersed into a semi-flowing tumbling state, and the full mixing is achieved
.
With the injection of adhesive, the powder is gradually wet, the shape of the material changes, and the squeezing, friction and pinching of the material by the stirring paddle and the cylinder wall are strengthened, thereby forming a wet and uniform soft material
.
These soft materials are gradually formed into small and uniform wet particles under the high-speed cutting of the whole grain of the granulating pulp, and then discharged by the outlet
.
The size of the number of particles is limited
by factors such as the characteristics of the material, the speed of the cutting knife and the granulation time.
Wet mixing granulator product features: 1.
Compared with the general mixing granulation equipment, improve the efficiency by 4-5 times, save the amount of binder used by 15-25%, and have a safety protection device to ensure safe production
.
2.
Paddle mixing speed, granulation knife speed is set and controlled by the frequency converter, which can be widely used in the granulation process
of various industries.
3.
The material is mixed in an all stainless steel container and granulated
.
4.
Three-way tumbling mixing, high uniformity, mixing, granulation is completed in one step, in line with the GMP requirements
of drug production.
The wet mixing granulator combines the powder material and the adhesive in a cylindrical or cone-shaped vessel, which is fully mixed into a wet soft material by the bottom mixing paddle, and then cut into uniform wet particles
by the side high-speed crushing paddle.
When working, several formulas of materials are added to the working container at one time, and the adhesive is injected after mixing and mixing, or the material of a formula is added to the working container at one time, and the soft material is mixed by the mixing paddle to make the soft material, and the cutting grinding knife crushes the soft material into granules
.
The high efficiency of the grinding knife is a two-speed motor, so the control of the solubility of the adhesive, the speed of the grinding knife, the grinding time can obtain particles of different particle sizes, to ensure that the production of drugs between batches, its particle size distribution, density, fluidity and other aspects of the quality reaches a high repeat level automatically produced according to the same procedure, to ensure the granulation quality
of the product.
