The method for producing carbon nanotube pellets according to the present invention can reduce the particle size of the carbon nanotubes contained in the pellet by a repetitive extrusion process to produce pellets having improved dispersion characteristics in a solvent. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.

The present invention concerns an extrusion die for extruding a food product having a humidity level between 2.5 to 6.5%, the extrusion die being intended to be connected to the end of an extruder, said extrusion die presenting in transversal cross-section: a circular central opened portion; and a peripheral indented opened portion comprising indentations in which the indentions are in communication with the circular central portion. The invention also relates to an extruder, process and method utilising said extrusion die and to an extruded or co-extruded individual food item produced using said extrusion die.

The present invention is directed towards a compacted powder shaped to comprise: a) a substantially annular girdle having opposing circumferential edges, the girdle having a diameter (x); and b) a dome protruding from each of the opposing circumferential edges of the girdle, wherein the height of each dome (hd) from the circumferential edge is, individually, about 0.18x to about 0.28x.

According to the invention, there is provided a method of compressing an uncured man-made vitreous fibre web, the web having two opposed major faces. The method comprising the steps: passing the web along a path; and subjecting the web to thickness compression by applying compression to the two major opposed faces of the web. Compression of each of said major faces of the web is applied by passing the path between converging continuous or discontinuous compression surfaces. Further, the respective major face of the web that is being compressed is in contact with one of the converging compression surfaces, and said converging compression surface is inclined towards the path. Additionally, each inclined converging compression surface applies an amount of compression to the major face of the web with which the respective inclined converging surface is in contact, wherein the amount of compression applied to at least one of the two opposing major faces of the web is adjustable.

A multi-chamber pellet die system to improve and increase analysis pellet manufacturing capabilities by allowing for multiple pellets or biomaterial scaffolds to be fabricated simultaneously.

The carbon nanotube pellets according to the present invention are produced by using only a small amount of solvent and have increased apparent density. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet rather than carbon nanotubes in the form of powder in composite materials. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.
