[0008]

According to the first aspect of the present invention, in the blasting apparatus, the workpiece is processed by blowing the ice particles together with the compressed air onto the surface of the workpiece. Thereafter, the ice particles are returned to the water, but the water flows out of the workpiece, so that the post-treatment is extremely easy.

[Blasting apparatus of claim 2]
In the blasting device of the above, the ice particles are formed by ice making means. In the ice making means, a proximity plate rotated by a motor is disposed in a state of being close to the upper surface of the tray portion, and water is formed between the tray portion and the rotating proximity plate in the form of ice particles.

[Blasting apparatus of claim 3] Claim 3
In the blasting apparatus, the workpiece is processed by spraying the solidified oil particles together with compressed air onto the surface of the workpiece. Thereafter, the granular material is returned to liquid oil. However, since the liquid oil flows out of the workpiece, post-treatment is extremely easy.

[0011]

Next, embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a granular material supply means for supplying the granular material 3, and reference numeral 5 denotes a compressed air supply means for supplying the compressed air 7. Granular body 3
For this purpose, ice granules or oil granules such as solidified turbine oil are used. The granular material 3 supplied by the granular material supply means 1 is compressed air 7 supplied by the compressed air supply means 5.
The granular material 3 is sprayed onto the surface of the workpiece 13 from the nozzle 11 while being dispersed in the compressed air 7. By blowing the granular material 3 together with the compressed air 7 onto the surface of the workpiece 13 in this manner, the workpiece 1
3 is performed. After the processing of the workpiece 13, the granular material 3 is returned to the liquid material 3 ′. That is, the ice granules 3 are returned to water, and the solidified oil granules 3 are returned to liquid oil.
Reference numeral 15 denotes a support for the workpiece 13. The granular material 3 has a diameter of, for example, about 0.3 to 1 mm. Note that a rust preventive may be mixed into the granular material 3 depending on the workpiece.

In the case where an ice granule is used as the granule 3, the granule supply means 1 may be configured to supply ice formed by an existing ice making device in the form of granules. Is provided with an ice making means 2 for forming water into ice granules 3, and the ice granules 3 formed by the ice making means 2 are supplied to the mixing section 9. That is, the ice making means 2 is provided with a saucer portion 23 in the cooling chamber 21, and a proximity plate 27 rotated by a motor 25 is arranged on the saucer portion 23 so as to be close to the upper surface of the saucer portion 23. Then, water 29 from the outside is supplied between the tray portion 23 and the proximity plate 27, and the water 29 is formed between the tray portion 23 and the rotating proximity plate 27 to form the ice granules 3. 3 is supplied from the cooling chamber 21 to the mixing section 9 via the supply path 31. Reference numeral 33 denotes a wall of the cooling chamber 21, and a cooling pipe 35 for cooling the wall 33 is provided in the wall 33. Reference numeral 37 denotes a cooling pipe provided in the tray 23, and the tray 23 is cooled by the cooling pipe 37. In the example shown in FIG. 2, the proximity plate 27 is attached to the lower end of the water supply pipe 41 rotated by the motor 25 via the transmission means 39. Reference numeral 43 in FIG. 2 denotes a bearing body of the support base 15, and reference numeral 45 denotes a drain port.

When peeling foods such as shrimp and vegetables using the blasting apparatus of the present invention, ice granules are preferably used. In this case, if the flow rate of the compressed air is appropriately controlled and the size of the ice particles is set to an appropriate size, the operation of peeling the food is preferably performed. Also, if the food is washed with water after peeling, the ice granules become water and do not remain as granules in the food. In the case of other workpieces as well, if the workpiece is washed with water after processing, the ice granules turn into water and flow out of the workpiece.

A blasting machine using oil granules is preferably used for various workpieces such as metals which are not adversely affected by oil. Oil particles remaining on the workpiece may be returned to liquid oil, for example, by heating the particles.

[0015]

According to the first aspect of the present invention, in the blasting apparatus according to the first aspect of the present invention, the workpiece is processed by spraying ice particles together with compressed air onto the surface of the workpiece. Thereafter, the ice particles are returned to the water, but the water flows out of the workpiece, so that the post-treatment is extremely easy. The blasting device according to the first aspect is preferably used for peeling shrimp, vegetables, and the like, and for processing various workpieces that are washed with water after the processing.

[Blasting apparatus of claim 2]
In the blasting device of the above, the ice granules are surely formed by the ice making means.

[Blasting apparatus of claim 3] Claim 3
In the blasting apparatus, the workpiece is processed by spraying the solidified oil particles together with compressed air onto the surface of the workpiece. Thereafter, the granular material is returned to liquid oil. However, since the liquid oil flows out of the workpiece, post-treatment is extremely easy. The blasting device according to claim 3 is preferably used for various workpieces such as metals that are not adversely affected by oil.
