A dual-airflow cyclone flash drying device includes a feeding device, a fluidizing cyclone generator and a drying cylinder. The fluidizing cyclone generator is connected with the drying cylinder through a central connecting pipe. The tail end of the feeding device is provided with a porous plate doser that is connected with the central connecting pipe. The fluidizing cyclone generator adopts lateral air supply, air forms a cyclone along the circular outer wall to enter the central connecting pipe. A drying cyclone generator is arranged at the lower portion of the drying cylinder. The drying cyclone generator adopts lateral air supply, and after forming a cyclone, air spirally rises to make contact with fluidized granular sludge to evaporate sludge moisture into water vapor. A particle size selector is arranged at the upper portion of the drying cylinder, and an outlet flue is arranged above the particle size selector.

A fluidized bed dryer may include a deck, an eccentric, and a blower. A heater may or may not be included. The deck of the fluidized bed dryer may vibrate due to motion of the eccentric. The blower may blow air through the deck of the fluidized bed dryer to dry material on the deck. As the material dries, the material moves across the deck, due to the vibration. The deck bed depth may be increased, which may allow for even process air flow distribution and control of conveyance speed and residence time. The fluidized bed dryer may include a controller configured to implement a drying process that may include one or more of temperature, moisture content, and relative humidity data to optimize product throughput while ensuring a desired degree of dryness.

The application relates to a process for drying a composition comprising an alkali metal salt of a compound of general formula (I) R.sup.1R.sup.2NCHR.sup.3COOM or formula (II) R.sup.1R.sup.2NCHR.sup.3CHR.sup.3COOM, in particular N,N-dimethyl glycinate salt, and the use thereof. In the process, the composition, in particular the N,N-di methyl glycinate salt, is dried by feeding the composition into a fluidized bed dryer and subjecting the composition to a heat treatment by contacting the composition in the fluidized bed dryer with a drying gas stream, and during the heat treatment a solution or dispersion of the composition is sprayed onto at least a portion of the composition present in the fluidized bed dryer, or alternatively or in addition the composition, in particular N,N-dimethyl glycinate salt, is fed into a fluidized bed dryer and subjected to heat treatment in the fluidized bed dryer by contacting the composition with a drying gas stream, and the temperature of the composition in the fluidized bed during the heat treatment does not exceed 50 C.

An object of the present invention is to provide a method for drying non-fried instant noodles for obtaining non-fried noodles that are easily loosened without sticking of noodle strings and excellent in restorability. The present invention includes, as a step of drying non-fried instant noodles, a step of putting gelatinized noodle strings into a drying retainer, and blowing a high-speed air flow from above the retainer toward a noodle mass of the noodle strings to perform drying. In the drying step, the retainer employed has a shape such that a transition portion from a bottom surface to a side surface (side wall portion) is formed to be a curved surface with a radius of curvature of 5 to 15 mm, and preferably the high-speed air flow is blown at a wind speed of 50 m/s or higher in terms of the speed to which the noodle strings are exposed.

A fluidized bed system is a single unitary modular system that packages a circulation fan, a fluidized bed, and a dust collection system within a same structure. The structure is formed to include internal ducts to provide fluid communication between the circulation fan, the fluidized bed, and the dust collection system. The fan provides a flow of air via a pressure duct to the fluidized bed. Particulate is separated from particles included on the fluidized bed by the flow of air being uniformly distributed to the fluidized bed. Particulate separated in a disengagement area and suspended in the flow of air is conducted through a particulate clearance space surrounding the dust collection system. The particulate is captured by the dust collection system and conveyed to a location external to the system.
