1, the working principle and components

The extrusion spheronizing machine is mainly suitable for the preparation process of the pellets. The working principle is to use the rotary screw to push the wet raw material to the ball cover, squeeze the material through the ball cover to grow the strip, and use the high-speed rotating sprocket to feed the long strip material. Rolling into dense ball pellets. The machine consists of two machines, an extruder and a rounding machine, sharing a control system.

Extruder overview

The extruder consists of a transmission system extrusion mechanism, a silo cabinet, an electrical control system, etc.; it is based on a unique low shear technology designed to reduce man-hour investment and temperature rise. It is ideal for heat sensitive products. A variety of extruded mesh apertures are available and available in a variety of configurations to optimize particle diameter, surface quality and product particle size distribution. Suitable for batch and continuous production, the extruder has no dead angle and no obvious material retention. The compact design makes installation and cleaning easier.

Extruder features

• High quality, easy to clean, high efficiency and low shear technology;

• Small footprint and a variety of extrusion screens to choose from;

• High-volume material handling capability with a simple extruder


Rounding machine overview

The rounding machine is composed of a transmission system, a toothed disc, a pot, a pot cover, a discharge, a mechanism and a frame. The spheronizer is characterized by a smooth, tight-fitting friction wheel to achieve good spherical particles and a uniform particle size distribution. This structural design eliminates the problem of the technical difficulty of fine powder in the conventional process. The optimization process is achieved by selecting the cycle time, turntable speed, product loading, friction mode and adjusting the airflow around the turntable.

 
Rolling machine features

• Good particle size, no fine powder, easy to handle, easy to clean;

• The spheronizer is fed directly from the extruder. For high volume applications, a continuous extruder can be used to dock two spheroids.

 
2, the extrusion rounding machine product features

• Short granulation time and high yield, no need for screening; high degree of automation and easy operation

• Process operation in a wet state to avoid dust flying and meet GMP and FDA requirements;

• The prepared pellets have narrow particle size distribution, high strength, high density, high product yield, high one-time pass rate, good reproducibility between batches, and can prepare drugs with high drug loading;

• The prepared pellets have good roundness, which creates excellent conditions for the coating operation of the next step, and greatly saves the cost of coating. The flowability of the pellets is good, which provides conditions for accurate measurement of capsule dispensing.


Third, the characteristics and structure of the extrusion spheronizer

1. Built-in cooling channel for air cooling and water cooling.

2. The process of preparing the wet material into pellets can be completed in one time.

3. The extruded ball cover adopts five-axis drilling processing, which makes the material extrusion balanced and efficient.

4. The innovative transmission system of DC brushless motor + planetary gear reducer is compact and easy to maintain.

5. The process operation is carried out in a wet state, and the dust is completely eliminated; the product yield is high, the roundness of the pellet is good, the surface is smooth, the tissue in the pellet is evenly distributed, the density is high, and the pass rate is high.
