A DAF skimmings separation system 10 that processes SPN/DAF skimmings 11 received from a meat processing facility to separate water and SPN-content solids includes a heating chamber coupled to a processor chamber having one or more pressurized discharge nozzles that expels DAF skimmings onto a spatter plate to cause SPN animal components within the DAF skimmings to break into smaller pieces denaturing the molecular structure and allowing the entrapped moisture to be evaporated within a heated airstream in the processing chamber, for separating nutritionally valuable SPN while reducing moisture content. A method of processing DAF skimmings to yield dryer SPN with reduced moisture content is disclosed.

A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.

A vortex dryer for fibrous material utilizes a helical inlet to the base of a central vortex tube to separate fiber from debris by abruptly changing direction of the conveying air flow. The dryer combines the helical input with helical shaping of the air flow through the central vortex tube to induce greater drying for the fiber which is continued at the top of the vortex tube through a separate drying chamber.

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 gasification process for efficiently co-producing synthesis gas and high-grade coal from water-containing coal, and to an integrated drying and gasification system for realizing the same.

A method of processing steel grit may include moving steel grit into a pre-classifier, weighing the pre-classifier with steel grit being processed by the pre-classifier, and altering a functional process to process the steel grit based on the weight of the pre-classifier including the steel grit. A machine for processing steel grit may include a pre-classifier configured to process steel grit to remove debris from the steel grit. A support member may be configured to support the pre-classifier. Multiple rotatable link assemblies may connect the pre-classifier to the support member to enable the pre-classifier to freely rotate as a function of gravity when supported from the support member. A weight sensor may be configured to weigh the pre-classifier including steel grit contained in the pre-classifier.

Herein is disclosed a spin flash dryer further comprising a waste outlet arranged in a chamber bottom of the spin flash dryer for removal of a residual organic waste material from a spin flash dryer during spin flash operation and a method of operating a such spin flash dryer to remove residual organic waste material from said spin flash dryer during operation.
