The present invention relates to a process for the control of Ostwald Ripening phenomenon occurring in particle suspensions without the need for addition of stabilizing agents, by using high pressure homogenization at mild conditions in a way that no increase or decrease in particle size occurs, thus allowing the stabilization of the suspension during the isolation step in the form of a dried powder.

Disclosed is a method, apparatus and system of drying wet toner particles which includes the use of cooling fluid. The method also includes introducing a heated drying gas into a toner drying chamber to create a circulating flow of drying gas.

The invention relates to the field of processing materials, and more particularly to a method for processing heat-sensitive materials in a vortex chamber, and can be used for drying, comminuting, heat treating and simultaneously separating into fractions such heat-sensitive materials as grass, straw, herbal raw material, vegetables and other materials, or mixtures of different plant materials, as well as for processing agricultural waste, in particular poultry droppings and horse or cow manure, into safe organic materials such as, for example, fertilizers. A vortex chamber contains a rotor for comminuting material and is designed to be volume-adjustable, wherein the lateral wall is configured in the shape of a right circular cylinder and the outer surface of the lateral wall and/or the lower wall of the vortex chamber are provided with additional openings for the removal of processed material. The invention is intended for obtaining several end products with different consumer properties (fineness, wetness, density, etc.) from a material, wherein said products can be obtained simultaneously.

The present invention relates to a method and facility for preparing lignocellulosic biomass, in particular by means of water extraction and optionally particle-size refinement, for subsequent use particularly in a process of torrefaction, carbonization, pellet production, such as fuel pellets or soil enhancement pellets, or the manufacturing of building materials, or even the preparation of agri-food products, comprising centrifugation (100) of the biomass followed by attrition milling and drying (200).

There is herein described apparatus for drying material or for conveying material. More particularly, the present invention relates to apparatus for drying conveyed material such as pneumatically conveyed material or for conveying oversized material.

A variable residence time drying system for moist material includes a valveless pulse combustor and a drying chamber. The drying chamber includes a lower sidewall with an upward expanding configuration that defines a lower inverted partial cone, an upper sidewall with an upward contracting configuration, a lifting rotor disposed within the lower inverted partial cone to suspend material being dried within a shear/drying zone, an opening through which moist material is fed into the drying chamber, and an exit located at a top portion of the drying chamber through which dried material exits the drying chamber. The valveless pulse combustor produces drying gas and sonic vibrations that are introduced tangentially into the shear/drying zone. One or more cyclones receive dried material and collect small particles. The lifting rotor may rotate in a direction counter to a direction in which the heated drying gas is introduced into the drying chamber.

A system and method for at least partially drying seeds treated with a liquid. A supply of heated air is continuously fed to a drying chamber. Treated seeds enter one opening of the drying chamber and are forced around at least a portion of the internal perimeter of the drying chamber before exiting out a second opening. Another embodiment can treat the seeds during and/or after the seeds entering the drying chamber.
