Abstract: Provided are a high-pressure jet impact chamber structure, with an industrial-grade “single orifice+single pulverizing chamber” design, and a multi-parallel type convenient pulverizing component adopted with the high-pressure jet impact chamber structure. The high-pressure jet impact chamber structure includes a body, a jet orifice, and a pulverizing chamber. The multi-parallel type convenient pulverizing component adopted with the high-pressure jet impact chamber structure includes a multi-parallel type chassis, a multi-parallel type connector disk, multiple high-pressure jet impact chamber structures that are parallel to each other, a sealing end cover, a discharge disk, and a discharge pipe.

Abstract: A device that effectively produce matcha powder is provided and includes: a stirred media mill grinding portion, having a grinding chamber inside, wherein a side of the stirred media mill grinding portion defines an outlet port; a pin bar, rotatably received in the grinding chamber, wherein an outer circumference of the pin bar defines an opening, communicated with the grinding chamber; an air classifier, connected to the outlet port through a first tube assembly and defining a first output port and a second output port; a storage portion, connected to the first output port; a collector portion, connected to the second output port through a second tube assembly; and a wind guider, wherein an air outlet of the wind guider is connected to the outlet port and an interior of the storage portion to create a negative pressure environment.

Abstract: The present disclosure provides a method for preparing fully soluble legume protein using a combination of stirred media mill and ultrasound technology. This method belongs to the field of food processing technology. The steps involved in this method includes: (1) mixing commercial legume protein with distilled water at a certain mass fraction (5-20%); (2) pouring the stirred protein solution into a colloid mill for coarse grinding, resulting in a coarse grinding solution; (3) heating the coarse grinding protein solution; and (4) pouring the heated, after cooling, into a media mill-ultrasonic coupling system for simultaneous grinding and ultrasonication, wherein the protein solution that has been ground and ultrasonicated is the high-solubility legume protein.
