Pharma Extruder
Hot-melt extrusion pharmaceutical is a proven manufacturing process that complies with FDA Process Analytical Technology (PAT) goals for designing, analyzing, and controlling manufacturing process programs.
This technology can produce granules, pellets, immediate-release tablets, controlled-release tablets, and Pellicle. At present, many drugs have been approved for marketing in foreign countries using hot melt extrusion pharmaceutical technology.
Statistics show that 40% of the drugs sold globally are poorly soluble drugs, and the proportion of poorly soluble drugs among the drugs under research is as high as 90%. Solubility has become a key factor affecting the development and application of such drugs. With the upgrading of the industry and the advancement of production technology, the “serial production” method may be gradually replaced by “continuous production”. Have her cake, and eat it, too — a technology that can not only improve the solubility of poorly soluble drugs but also realize continuous production mode – hot melt extruder machine, has emerged.

Xinda is a manufacturer specializing in the research and manufacture of compounding extruders. For the pharmaceutical industry, we have developed 11mm and 20mm hot melt extruder machine.
Working Principle
Hot melt extrusion pharmaceutical a technology that mixes drugs and polymers and other excipients in a molten state, and extrudes them at a certain pressure, speed, and shape to form products.
After the powder raw materials and auxiliary materials are fully mixed, they are evenly transported to the feed port through the feeding system, and then the API and drug carrier are evenly transported to the temperature-controlled barrel by the twin screw. The barrel is equipped with threaded elements, which perform different unit operations from the feeding position to the die head in sequence. The material moves forward under the conveying action of the threaded elements and melts or softens in the melting section. The melt is evenly mixed under the action of the mixing elements and finally extruded from the die at a certain pressure, speed and shape.
Equipment
There are two main types of hot melt extruder machine, plunger type, and screw type. Plunger extruders are gradually eliminated due to their weak mixing ability. Screw extruders are divided into single-screw, twin-screw and multi-screw. Single-screw and twin-screw extruders are most widely used in the formulation field.
The single-screw extruder is an integral structure, which consists of cooling hopper area, solid conveying area, melting area, and melt conveying area. The twin-screw extruder is a combined structure, which consists of five parts: solid conveying zone, melting zone, mixing zone, exhaust zone and melt conveying zone.
Benefits
Hot melt extrusion pharmaceutical provides sufficient mixing and shearing. The shearing force comes from the meshing elements, and the drug can be highly mixed and uniformly dispersed in the carrier material. The dissolution rate of the drug is greatly improved, and a highly mixed and uniformly dispersed shaped product can be obtained, which can also improve the release of the drug in vivo. In order to meet the needs of different compounds and preparations, hot melt extrusion technology has many advantages:
- Use a twin-screw feeder to ensure uniform and stable feeding.
- Use segmented electric heating to ensure uniform and stable heating without temperature contamination.
- Combined twin-screw design allows you to freely select thread elements and thread lengths according to material characteristics.
- The extrusion die aperture can be selected with different apertures and different shapes of die heads according to needs.
- Cooling and crushing devices of different structures can be configured according to different material characteristics.
- Quick design, simple installation and disassembly, easy to clean.
- Customized services can be provided according to customer needs.
- Comply with industry regulations such as GMP, FDA, and EU.
- High-quality DQ, IQ, and OQ verification document system.
