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.

A jet milling apparatus comprises a milling chamber having one inlet for a product to be milled and outlets for a milled end product having physical properties with respective values falling inside respective ranges, nozzles for issuing respective jets of a milling fluid having predetermined operative parameters into said milling chamber for intercepting the product to be milled and forming a fluidized material inside for drying, selecting, milling, sterilizing, clustering the product, electromagnetic field emitters designed to generate an electromagnetic field with predetermined frequencies and to orient it inside said milling chamber, monitoring devices placed at the outlets for controlling in real time the physical properties of the milled end product before exit and designed to drive the nozzles and the electromagnetic field emitters to vary and adjust the operative parameters of the jets of the milling fluid and the frequency of the electromagnetic field.

A method for producing resin particles includes drying resin particles in a wet state by passing, without circulating, the resin particles through a drying tube together with a first gas, the resin particles being ones that undergo pressure-induced phase transition. The drying tube has an inlet through which the resin particles are fed into the drying tube, at least one gas blowhole through which a second gas is blown over the resin particles passing through the drying tube, and an outlet through which the resin particles are ejected from the drying tube, and the second gas is blown out of the gas blowhole at a velocity of 50 m/s or more.

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 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 a method for grinding and drying a material or material mixture (M), using a cyclone device (10) which communicates with an outlet line (52) for gas (G) and material (M) processed in the cyclone device (10), wherein at least a portion of the gas (G) and material (M) in the outlet line (52) are returned into a lower opening (14) of the cyclone device (10) for further cyclone treatment. The invention relates also to an apparatus.

An apparatus for drying bulk particulate material, and having an inlet chamber for receiving a moist bulk particulate material and an outlet chamber for ejecting a dry bulk particulate material. The inlet chamber comprises a steam permeable bottom being divided into a number of subsections including a first subsection and a second subsection. Each subsection defines a first and a second radial centreline. The first subsection and the second subsection each having at least one louvered plate section comprising a plurality of louvers arranged in a first and a second specific direction, respectively, for directing superheated steam in a first and second blowing direction, towards said lower cylindrical inner wall. The specific direction of the louvers of the first subsection defines a first angle in relation to the first radial centre-line, and specific direction of said louvers of said second subsection defines a second angle in relation to said second radial centreline, and said first angle and/or said second angle, being different from 0 degrees.

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.
