Abstract
Apparatus and process for simultaneously milling, dehydrating and/or sterilizing a material by introducing the material into a chamber comprising rotating instruments while substantially simultaneously introducing a hot gas into the chamber. Gas and material are introduced tangentially to the chamber at points opposed from each other, and the gas and material both enter the chamber in the same direction as the rotating instruments.
Claims27
An apparatus for milling, drying, or sterilizing a material, comprising:
- a cylindrical chamber housing;
- at least one rotor rotatably mounted and axially aligned in the chamber;
- a first inlet of the chamber adapted to supply material during use tangentially to the chamber such that the material enters the chamber during use in the same direction as the rotation of the rotor;
- a second inlet of the chamber adapted to supply hot gas during use tangentially to the chamber such that gas enters the chamber during use in the same direction as the rotation of the rotor;
- and
- an outlet orifice of the chamber substantially axially aligned at one end of the chamber and adapted for allowing material to exit the chamber.
3 more elements
A process of milling, drying, or sterilizing a material, comprising the following steps:
- tangentially introducing material into a cylindrical having at least one rotating instrument(s) such that the material enters the chamber in the same direction as the rotation of the instruments;
- tangentially introducing hot gas into the chamber such that the gas enters the chamber in the same direction as the rotation of the instruments and the material is dried and reduced in size by contacting the hot gas and the instruments.
