[Example] Example 1. An embodiment of the present invention will be described below with reference to the drawings. Figure 1
In FIG. 2, 4 is a conveying device consisting of a belt conveyor, 5 is a feeding device that supplies a fixed amount using a vibrating hopper, etc., 6 is a cylindrical net conveyor, and a net 7 is formed of a hollow cylindrical crushed body whose inner periphery is made of a fine mesh. A draining section 8 is provided near the opening at one end, and a cooling section 9 is provided along the longitudinal direction up to the opening at the other end, and further rotatable in the circumferential direction by a drive device 10. In addition, the cooling section 9
It is supported at a predetermined angle so that it faces downward. 11
12 is a cooling device provided outside the cooling section 9 and has a fan 13; and 14 is a delivery device consisting of a belt conveyor.

Next, the operation will be explained. For example, a granular food 3 with moisture attached to its surface, such as rice that has been soaked in water and contains a certain amount of moisture in order to cook deliciously, or beans that have been washed in water, is continuously conveyed by a conveying device 4, and is continuously conveyed by a feeding device 5. A fixed amount is then placed into the cylindrical net conveyor 6. The cylindrical net conveyor 6 is installed in an inclined manner with the draining portion 8 provided near one of the openings into which the net is fed facing upward, and is rotated in one direction along the circumferential direction by a drive device 10. The introduced granular food 3 with moisture attached thereto moves in the rotation direction due to the frictional force with the net 7, and as it rises, it naturally falls due to gravity, and the moisture attached to the surface is removed during this period. This removed water is drained to the outside through a water receiving portion 11 provided below.

The granular food 3 in this wet state is sequentially moved downward according to the inclination angle of the cylindrical net conveyor 6, and in the cooling section 9, the cool air generated by the cooling device 12 is transferred to the net by the fan 13. While blowing the granular food 3 inward through the hole 7, the water adhering to the surface is frozen, forming an ice film to cover it and rapidly freezing it.

The frozen granular food 3 is transferred from the cylindrical net conveyor 6 to the carry-out device 14, and is packed in predetermined amounts into containers (not shown).

Example 2. FIG. 3 shows another embodiment, and in the figure, 15 is a moisture supply section provided near the opening at one end of a cylindrical net conveyor 6 supported at a predetermined angle, and 16 is a moisture supply section 15. This is a moisture supply device installed outside of the In addition,
The rest of the configuration is the same as that of the first embodiment, so a description thereof will be omitted.

Next, the operation will be explained. The granular food 3 with a dry surface is continuously conveyed by a conveying device 4, and a fixed amount is transferred by a feeding device 5 onto a cylindrical net conveyor 6.
Put it inside. The cylindrical net conveyor 6 is installed at an angle with the moisture supply section 15 provided near one of the input openings facing upward, and is rotated in one direction along the circumferential direction by a drive device 10. . The introduced granular food 3 moves in the rotating direction due to the frictional force with the net 7, and as it rises, it naturally falls due to gravity. Moisture, for example, water in the form of mist, is sprayed onto the granular food 3 in this state from a moisture supply device 16 provided on the outside, so that the entire surface of the granular food 3 is coated with moisture.

Granular food 3 with a wet surface as described above
As the cylindrical net conveyor 6 rotates, it sequentially moves downward according to the inclination angle and is guided to the cooling section 9. The operations after the cooling unit 9 are the same as those in the first embodiment, so the explanation will be omitted.

Example 3. FIG. 4 shows another embodiment, in which straight or spiral scraping portions 17 are provided protruding from the inner surface of the cylindrical net conveyor 6 along the longitudinal direction, and a plurality of scraping portions 17 are arranged along the circumferential direction. It has been done. As the cylindrical net conveyor 6 rotates, the granular food 3 is scraped up by the scraper 17, and as it falls, the single granules are separated and reversely stirred, and the granular food 3 is drained, moisture is attached, and ice film is formed. This improves refrigeration efficiency.
