通過することで板状に凍結が行なわれることである。Next, a series of operations of the above-mentioned structure will be described. A liquid material such as coffee and juice in an aqueous solution is charged into the stock solution tank 11, and a high-pressure liquid material is directly discharged from the spray nozzle 2 via the delivery pump 12. By spraying in a mist shape onto the mesh belt 3 of the above, a deposition layer of fog droplets having a substantially uniform particle size is formed on the mesh belt 3 and moved by the belt 3, and the fan 5 cools the cooler 4
The cold air blown out from the mesh belt 3 passes through the mesh belt 3, and the fog droplets accumulated on the upper surface of the mesh belt 3 are rapidly cooled and frozen in the accumulated layer a.
To form. Next, the frozen accumulated layer a at the outer end turning portion of the belt 13 is separated into a porous accumulated layer a (formed in layers by a collection of fog droplets) which naturally forms on the upper surface of the mesh belt due to the direction change of the mesh belt. It is peeled off and dropped into the kneading and loosening machine 6. In the rubbing and disintegrating machine 6, the separated deposited layer is crushed to form granules of the original size of fog droplets, and the fine powder generated at that time and the granules of a predetermined particle size are sieved by a shifter 7 Of the granules are sent to the FD device 8 through the pipeline L 1 , and the sieved powder is heated and melted by the melt tank 9, and the pump 1
At 0, it is returned to the inside of the stock solution tank 11 through the pipeline L 2 , and is again sent to the spray nozzle 2 by the pump 12. That is, in the above operation, the most gist of the present invention is the action in the low temperature chamber, in which the pre-cooled liquid substance is atomized and dropped from the spray nozzle 2 into the low temperature atmosphere in the low temperature chamber 1 in the heat insulating state. In addition, by cooling the mesh belt 3 so that it can be maintained at a temperature slightly higher than the freezing temperature immediately before reaching the mesh belt 3, it does not freeze as it approaches the mesh belt, but the viscosity of the fog drops gradually increases, When they reach the top, they are bound to each other in a point-contact state while retaining their grain shape without fusing and integrating with each other, and they move together with the belt, causing the cold air to pass through from below and freeze into plates. Is to be done.

生産性,品質共に良好である。As described above, according to the present invention, a liquid substance is ejected in a mist state from a spray nozzle in an adiabatic low temperature chamber, and is cooled so that it can be kept in an unfrozen state until just before reaching a mesh belt. Since the freezing gradually progressed from the time when it reached the fall, it was peeled off naturally due to the turning of the belt and it was rubbed and loosened, so it can be crushed like a conventional example or sieved by a shifter in many ways. Eliminates time, waste of energy can be significantly reduced, and at the same time economical
Both productivity and quality are good.
