本考案は着脱式冷媒噴射装置を有する摩砕機に
関し、特に砥石や摩砕室内を効率よく冷却できる
ものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a grinding machine having a removable refrigerant injection device, and is particularly capable of efficiently cooling a grinding wheel and a grinding chamber.

Conventionally, this type of grinder consists of an upper fixed grindstone and a lower rotary grindstone, the gap of which can be freely adjusted in the grinding chamber.The raw material is fed from a hopper attached to the upper end of the grinding chamber between the upper and lower two grindstones. The grinding material is sent to the grinding chamber, and is gradually made into ultra-fine particles by the strong shearing, compression, and grinding forces generated in the gap, and then discharged to the outer periphery of the grinding chamber around the grindstone.

機の性能を十分に発揮できないことが多かつた。 However, when a highly hard material or dry material is used as the raw material to be milled, the frictional heat of the grindstone is high, and the resulting thermal expansion deformation may cause the grindstone to crack or break. In particular, when the gap between grinding wheels is reduced to zero or extremely small in order to obtain ultrafine particles, this tendency is strong, and the performance of the grinder is often not fully demonstrated.

極力阻止することが重要である。 In addition, the efficient grinding of various materials such as meat and pre-crushed livestock bones at low temperatures is an extremely important technology in the food industry. It is necessary to crush it, and it must be atomized without oxidation or protein denaturation. Therefore, it is important to prevent a large amount of heat generation during grinding as much as possible.

A plurality of blocks each having nozzles that eject refrigerant at a wide angle toward the center of the fixed frame are installed approximately perpendicularly to the fixed frame surface, and are connected to supply refrigerant to these nozzles. A refrigerant injection device provided with a pipe is characterized in that the nozzle penetrates into the inside of the grinding chamber from the outside and is detachably attached so that the nozzle is positioned around the fixed grindstone and the rotary grindstone. That is.

A specific method for attaching a refrigerant injection device having such a configuration to a grinder is to attach nozzles that are installed approximately perpendicularly to each block to the top cover of the grinding chamber of the grinder at the same annular position as the nozzles. Then, each block is inserted from above into the through holes drilled on the outside of the outer periphery of the upper and lower grindstones in the grinding chamber, and each block is attached to the upper surface of the upper cover with bolts or the like. Since each nozzle is integrated with the annular fixed frame in this manner, it has the advantage of being easy to handle and easy to attach and detach from the grinder.
