BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing granular products, and more particularly to a novel method for producing edible granular products such as artificial fish eggs.

0002

BACKGROUND OF THE INVENTION There have been many proposals regarding methods for producing granular materials. For example, a method in which droplets are created by allowing a liquid stream to fall naturally into the atmosphere using a nozzle (for example,
9-151,850), and liquid flow is a method of forming droplets by dropping into an incompatible liquid (for example, Japanese Patent Publication No. 1973-
No. 8,863).

In addition, as a method to improve the productivity of the above method, there is a method in which droplets are created by vibrating a nozzle (for example, Japanese Patent Application Laid-open No. 112,831/1983), and a method in which droplets are created by vibrating a nozzle (for example, Japanese Patent Application Laid-open No. 112,831/1983) is a method in which droplets are created by vibrating a nozzle. There is a method (for example, JP-A-52-78,775) in which liquid is extruded and a ring body surrounding the jet stream is vibrated to form droplets. However, the above-mentioned method has a problem in productivity, and it has been eagerly desired to develop a method for producing granules with excellent productivity.
