A cylindrical drum having a plurality of vanes which extend radially into the drum and extend axially substantially the length of the drum rotates about its axis such that the plurality of vanes convey vegetable material from a lowest point in the interior of the drum to a highest point in the interior of the drum, there, to drop the vegetable matter downward within the interior of the drum. A plenum feeds air through a nozzle opening in a rectangular slot extending in its longest dimension substantially the length of the drum. The plenum and nozzle being housed to form a Coand{hacek over (a)}-effect nozzle body having a tear-shaped housing. Two Coand{hacek over (a)} surfaces are situated in opposed relation terminating at the nozzle. The Coand{hacek over (a)} surfaces to guide air into a combined flow. A hopper plate cooperates with the housing to form a hopper directing vegetable matter to collide with the combined flow.

This invention relates to a rotary dryer with multi-drying chambers which is developed and improved for drying materials such as cassava chip, paddy, corn, various crops, longan, fertilizer, biomass and mining industry with better drying efficiency.

Provided herein are systems, methods, and processes for drying a softgel having a hydrophilic fill material and one or more active ingredients. After forming the hydrophilic softgel, for example, the softgel is dried by sequentially passing the softgel through a series of specific drying conditions, in which the first drying condition has a low temperature and low dew point. In certain examples, controlled airflow is also used to dry the softgels. By using the systems, methods, and processes, the total time to dry the hydrophilic softgel can be beneficially reduced from several days to about 24 hours without causing shriveling of the softgel.

A baghouse apparatus for removing particulates from a 100% recycled asphalt pavement dryer exhaust air stream includes a drop out zone section having a water spray operable to initially drench an incoming air exhaust stream with water droplets while increasing air stream velocity, then slow the air stream velocity to cause drop out of particulates >1000 m from the slowed waste air stream, and collect the particulates dropped out of the waste air exhaust stream. The apparatus also includes a cyclonic scrubber section for further cooling the waste air exhaust stream while subjected the stream to a further water spray to condense aerosol vapor into droplets, a prefilter filtration section operable to collect and remove condensed aerosol droplets from the waste air stream; and a coalescing filtration section operable to remove 99% of remaining particulates from the waste air stream before discharge of the air stream to atmosphere.

The invention relates to a method for freezing injectable compositions, in particular pharmaceutical compositions. The method comprises: storing a quantity of a dispersion of an injectable composition in an aqueous dispersion medium in a vial; cooling the vial by applying cooling gas to the vial, the cooling characterized by performing at least one of (A), (B) and (C), wherein (A) is an initial cooling control scheme before nucleation has occurred in the dispersion layer, (B) is a crystallization control scheme during crystallization of the dispersion layer, and (C) is a final cooling control scheme after the dispersion layer has crystallized; and obtaining the dispersion after freezing is complete.

A method for drying bulk goods, in particular wood fibers and/or wood chips, wherein the bulk goods is continuously dried in a dryer (1), in particular a drum dryer. The vapor-gas mixture flows through the drum dryer (1) in a dryer circuit and is indirectly heated via at least one heat exchanger (4) by a burner waste gas that is heated in at least one burner (5). The drying vapors are supplied to the at least one heat exchanger (4). Upstream, downstream and/or within the at least one heat exchanger (4), at least a partial flow of the drying vapors are branched off to be conducted into the burner (5). The remaining partial flow is conducted to the dryer (1) again. The partial flow of drying vapors to the burner (5) is driven by at least one regulable partial vapor fan (10).
