A flexible connection channel 101 made of rubber or the like is provided between the liquid reservoir 13 and the liquid reservoir 13. By providing the trough-shaped channel 11 via the flexible connection channel 101 in this manner, the inclination angle of the trough-shaped channel 11 is changed, and the flow velocity of the frozen liquid A flowing down is changed to the liquid refrigerant C.

It is also possible to drop the liquid to be frozen A uniformly on the passage 3. Furthermore, by applying appropriate vibration to the gutter-shaped flow path 11, particularly in the same direction as the flow direction of the liquid to be frozen A, droplets can be easily generated even when freezing a highly viscous material to be frozen. Can be formed.

02 may be provided, and as shown in FIG.
An appropriate through-hole 103 may be provided at the bottom of the container to allow the liquid to be frozen A to flow down from the through-hole 103 into the trough-shaped channel 11, or other suitable liquid amount adjusting means may be combined.

However, the particles can be separated into particles in the vicinity of the liquid refrigerant C flowing through the refrigerant channel 3. That is, in the case of producing substantially uniform and almost perfect spherical ice particles, when the liquid to be frozen A is made to flow from a lower position as shown in FIG. 2, it is made into a droplet shape when leaving the tip of the gutter-shaped channel 11. Although it is necessary to keep it in advance, when the liquid A to be frozen is allowed to flow down from a high position, the liquid A to be frozen can be continuously flowed down, and the productivity can be improved. If the shape and size of the ice particles are not so particular, the liquid to be frozen A may be continuously flown into the liquid refrigerant C.

Each of the plurality of V-shaped flow paths has a one-to-one correspondence. By forming in this way, when the frozen liquid A that has fallen from the adjacent gutter-shaped channel 11 freezes in the flow of the liquid refrigerant C, the ice generated in the direction perpendicular to the flow of the liquid refrigerant C is formed. The particles can be prevented from sticking to each other, and the amount of the liquid refrigerant C used can be reduced.
The bottom shapes of both flow paths are most preferably the above V-shape, but they may be flat bottoms or round bottoms, and the flow path cross sections may be different between the upstream side and the downstream side.

An air motor or the like can be used. Further, by introducing a refrigerant vapor vaporized in the refrigerant flow path 3, for example, nitrogen gas from the hood 125 through the pipe 126 into the central portion of the cylindrical case 121, a gas flow from the center to the outer periphery is formed in the impeller 122 portion. It is possible to prevent the frozen liquid A from adhering to the central portion of the impeller 122 due to a negative pressure in the central portion, and the frozen liquid A can be charged smoothly.

着も防止でき、効率良く氷粒を製造することができる。As described above, in the ice particle producing apparatus of the present invention, the liquid material to be frozen is dripped into the flowing liquid refrigerant from the liquid material charging means having a simple structure such as a gutter-shaped channel. Since it is frozen, it is possible to form the entire device with a simple configuration, the cost of the device can be reduced, and since it is frozen in the flow of the liquid refrigerant, it is possible to produce substantially uniform spherical ice particles. In addition, it is possible to prevent the generated ice particles from sticking to each other and efficiently produce the ice particles.
