Extrusion and Co-extrusion: A Technology in Probiotic Encapsulation with Alternative Materials

Current Pharmaceutical Biotechnology
: Encapsulation, in particular extrusion and co-extrusion, is a common practice to protect probiotics from the harsh conditions of the digestive tract as well as processing. Hydrocolloids, including proteins and carbohydrates, natural or modified, are a group of ingredients used as the wall material in extrusion.

The Extrusion of Rate Sensitive Materials

1971
The principal factors affecting extrusion pressure, viz., temperature, ram speed, die geometry and conditions of lubrication, are discussed briefly. Emphasis is given to the importance of determining the area profile of the die, and through it the strain rate profile.

Extrusion of implanted materials

1985
Generally, extrusion is interpreted as a reaction of the body to non- tolerated implants. This applies to many uses of various materials in different surgical fields. Middle ear implants are used for very different purposes (e.g. ossicular replacement prostheses, grommets, sheat- ings, posterior canal wall implants, materials for obliteration).

Extrusion‐Spheronization of Energetic Materials

Propellants, Explosives, Pyrotechnics
ABSTRACT The prevailing method to produce plastic‐bonded explosive (PBX) molding powder, or “prills”, is a complex, multiphase, and bespoke process that was developed by the high explosives (HEs) manufacturing industry several decades ago.

Capillary extrusion of composite materials

Polymer Engineering & Science, 1971
AbstractInvestigations on the extrusion characteristics of composite systems were performed on the Sieglaff‐McKelvey capillary rheometer, with particular emphasis on the characterization of flow instability and “melt fracture” phenomena. The mechanisms of melt fracture appear to be identical for both the filled and unfilled polymers (1.

Conversion of a 11 MN Extrusion Press for Hydrostatic Extrusion of Superconducting Materials

1990
The purpose of this program was to demonstrate the feasibility of modifying an existing mid-size conventional extrusion press to permit, with a simple tooling change, hydrostatic extrusion of superconducting materials. Hydrostatic extrusion is considered by many the ideal method for low-temperature processing of superconductors in order to (a) maximize
