The binder liquid is sprayed in the stirring tank 21, and this is
A device for continuously producing granulated material by stirring to generate a spiral circulating flow has been used [Practical latest granulation technology (Comprehensive technical data collection), pp. 36-39, Please refer to Kanagawa Prefectural Management Development Center Publishing Division, published in 1984. ]
However, since the granulation is performed using the cohesion phenomenon of the powder due to moisture, the range is relatively wide as in the case of powdered milk, the water content is said to be 5 to 15%, soy sauce and various extracts In the case of amino acid-containing substances such as the above, the water content is said to be 5 to 8%. However, in an actual device, if the moisture (moisture) is low, the progress of granulation is slow, and if the moisture is high, the device adheres or forms a dumpling, and the appropriate range is very narrow.
The content is within a few percent for powdered milk and within 1% for amino acid-containing substances, and high control is required.

る。Further, in the spray drying device, it is necessary to sufficiently dry the material to be transported to a subsequent device, and in many cases, the temperature of the exhaust gas from the tank and the humidity in the tank must be reduced. For this reason, it is necessary to supply secondary cold air into the tank, and as an after-treatment facility for introducing the secondary cold air, ancillary equipment such as a blower and a wet scrubber also need to have a large capacity.

撹拌造粒部においてバインダー液で造粒される。[Effects of the Invention] Since the fluidized granulation nozzle 5 is provided in the stirring granulation section 3 separately from the stock solution supply sprayer 4, the spray drying section cone section 2b has:
It is not necessary to keep the fine particles of the stock solution in an incompletely dried state with high moisture. Therefore, the fine particles are dried in a wide drying range, do not adhere to the wall surface in the layer, and are granulated with the binder liquid in the next stage of the agitation granulation section.
その結果、造粒品の回収率が向上できる。 As a result, the recovery rate of the granulated product can be improved.
