The present invention relates to a system for one pot solids recovery from solutions, slurries, emulsions, dispersions, gels, semisolids, and their like. Further the system can be used for controlled concentration of solutions, slurries, emulsions, dispersions, gels, semisolids, and their like to enable easy to operate cost effective energy efficient processes. The system is so constructed to enhance the contact between the liquid medium and the gaseous medium used in the process for effective heat transfer. The system can be used for controlled concentration and/or recovery of substantially dry solids in applications related to foods, nutraceuticals, natural products, pharmaceuticals, chemicals, etc.

A waste disposer comprising a primary dehydrating chamber, a grinding device, a secondary dehydrating chamber, and a storage chamber. The primary dehydrating chamber is adapted to allow waste to be heated therein to partly dehydrate the waste. The primary dehydrating chamber has: a first waste inlet for receiving the waste, a first vapor outlet for exhausting vapor from the waste, a drainage outlet for draining free liquid from the waste, and a first waste outlet for outputting the partly dehydrated waste. The grinding device is adapted to receive the waste from the first waste outlet and grind the waste to reduce the size thereof. The secondary dehydrating chamber is adapted to allow the ground waste to be heated therein to further dehydrate the waste. The secondary dehydrating chamber has a second waste inlet for receiving the ground waste, a second vapor outlet for exhausting vapor from the waste, and a second waste outlet for outputting the further dehydrated waste. The storage chamber is adapted to receive the waste from the second waste outlet and store the waste in the storage chamber.

There is provided an apparatus for use in drying a sample of geological material having a substantial moisture content. In one aspect, the apparatus comprises a means for providing a flow of heated fluid, and a means for managing the thermal state of the flow of heated fluid. The means for managing the thermal state of the flow of heated fluid is arranged operable with the means for providing a flow of heated fluid so that exposure of the sample to the flow of heated fluid facilitates a reduction of the moisture content of a portion of the sample while substantially preserving one or more chemical and/or physical properties of the portion.

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.

A system and method for staged drying of temperature sensitive materials, the method comprising the following steps. Heated air is blown into a duct and solids are introduced into the duct at an elevated position along a vertical portion of the duct. The heated air and solids mixture is then transported along the duct for a desired retention time with adequate initial flash heating of the solids and then a gradual cool down of the solids. The solids are at an elevated temperature beyond the ambient dewpoint with evaporative cooling taking place. The solids and air mixture is then transported in the duct to a cyclone, where the solids are removed from the air. The air is exhausted out of the cyclone by an exhaust duct, and the solids are collected from the cyclone in a container.

The present invention refers to an accelerating cyclone that separates solid particles, comprising in its general structure a lower conical body (1) (17A and 17B), comprising a lower opening (18), a central cylindrical body (2) immediately above the conical body (1) whose diameter is smaller than the largest diameter of the conical body cone (1), and a third upper, also cylindrical, body (3) of smaller diameter than the diameter of the central cylindrical body (2), comprising a side opening for the acceleration air output (5); where the cylindrical central body (2) allows to accelerate the speed of the solid material particles and is the cyclone pressure chamber; and where said cylindrical central body (2) comprises a side opening for the acceleration air input (8) and at least one duct (9).

Moisture is removed from particulate material using an apparatus comprising a dryer having a drying chamber for directing a flow of gas-entrained particulate material between first and second ends of the drying chamber. The dryer is configured for directing gas under pressure into the drying chamber, for interacting with a flow of gas-entrained particulate material within the drying chamber. The dryer comprises a body of modular construction, which defines a plurality of guide passages arranged for fluid communication between the drying chamber and a source of gas under pressure. The body of modular construction comprises a plurality of discrete annular elements, arranged in series, one adjacent another, each having a body defining a central aperture, and wherein the annular elements are arranged together with the central apertures aligned.

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.
