摘要:
A nozzle assembly is provided for use in apparatus for treatment of particulate material wherein the particulate material is conveyed through a treatment zone in fluidized condition, said fluidization being accomplished by a high velocity flow of gas directed against an imperforate member provided by the conveyor which gas flow is discharged from an elongated slot defined by the nozzle assembly and whose lengthwise direction extends in the direction that the particles are conveyed.
摘要:
A process for drying a particulate plant material for use in a food product is provided which includes the step of subjecting the particulate plant material suspended in a fluid stream to an elevated temperature to dry the particulate plant material. The invention also provides food products comprising said dried particulate plant materials.
摘要:
This invention relates to a process and an appliance for drying byproducts from the processing of starch-containing and sugar-containing raw materials, in particular, after their fermentation and distillation, where the byproduct is fractionated in a purification phase with a high liquid proportion and a thick phase, whereby the thick phase is shaped into particles in a conditioning procedure and whereby these particles are dried in a fluidized-bed drying system with a relative gap volume, in the fluidized-bed layer, between 0.5 and 0.92.
摘要:
A desiccating device and method providing variable drying conditions allowing the desiccated material to substantially maintain its natural characteristics upon rehydration as well as have a low microbial content. The method provides a process of subjecting the material to ultrasound and flowing hot air or gas for a defined period of time. The ultrasonic frequency, temperature, air flow and time of exposure can be varied to produce the most efficient drying conditions depending on the material to be dried. The apparatus has plurality of drying chambers with forced heated air or gas input and output ducts and ultrasonic emitter. The material passes through each chamber at a pre-determined rate on a perforated conveyor belt in one embodiment of the invention. Optionally, the material may be placed on a drying bed or substrate comprising a number of spheres.

A fluidized bed particulate material treating apparatus is provided having a fluidizing bedplate formed with apertures of a frusto-conical configuration. The apertures are formed with walls divergent from an exit end at an angle in the range of 25-45 degrees with a plurality of apertures formed in the bedplate in closely spaced relationship resulting in interaction of the airflow from the apertures to levitate the material as it is transported over the bed by the air flowing through the apertures.
摘要:
A fluidized bed apparatus for treating particulate material comprising a foraminous support such as a perforate plate, a screen, or the like, gas supply means to supply a fluidizing gas beneath said support and a plurality of movable flights above said support adapted to sweep fluidized material along the support. The apparatus is useful for obtaining controlled residence time of materials being treated within an enclosed treating chamber.
摘要:
A method for preserving organic piece goods, for example, foods such as fruits, plants, parts thereof, small animals, and animal piece goods, and organic piece goods from the non-food sector, for example, cut flowers, using a dehydrating solvent and by drying in a drying device, and a for producing preserved organic piece goods involves drying the piece goods are dried in a drying device in the presence of the solvent at temperatures below 100° C., preferably in a fluidized bed. The procedure has the advantage of significantly lower drying temperatures compared to freeze drying, requiring substantially shorter drying times, and thus having significantly better energy efficiency, and being more environmentally friendly. The drying procedure is gentle, wherein the organic piece goods substantially retain the original shape, color, and contents thereof.
