Jet device for mixing fluid

Abstract

A grinding and/or polishing machine for grain crops such as rice, wheat or other types of grain crops, comprising a grinding rotor surrounding a sifting basket. The grinding rotor is embodied as a hollow shaft and has openings enabling air to enter the working area. The air enters the hollow shaft via an upper and a lower air inlet. The working area is defined by a vertically displaceable catchment plate on the side of the product outlet. The displaceability of said catchment plate is adjusted by a membrane drive.

1 . A grinding, polishing or paring machine with horizontally or vertically arranged working area formed between a rotor fitted with tools and a perforated basket, the product outlet of which can be sealed with a baffle plate, and wherein the rotor is designed as a hollow shaft with air through openings, wherein the baffle plate can be continuously actuated by means of a membrane drive.  
   
   
       2 . A grinding, polishing or paring machine with vertically arranged working area formed between a rotor fitted with tools and a perforated basket, wherein the rotor is designed as a hollow shaft with air through openings, wherein the hollow shaft has an upper and a lower air inlet.  
   
   
       3 . The grinding, polishing or paring machine according to  claim 1 , wherein the air through openings are longitudinal, running in the axial direction.  
   
   
       4 . The grinding, polishing or paring machine according to  claim 1 , wherein the rotor is wedge-shaped.  
   
   
       5 . The grinding, polishing or paring machine according to  claim 1 , wherein the hollow shaft has an upper and a lower air inlet.  
   
   
       6 . The grinding, polishing or paring machine according to  claim 2 , wherein he product outlet of the working area can be sealed by means of a movable baffle plate.  
   
   
       7 . The grinding, polishing or paring machine according to  claim 6 , wherein the baffle plate can be actuated by means of a membrane drive.  
   
   
       8 . The grinding, polishing or paring machine according to  claim 2 , wherein the air through openings are longitudinal, running in the axial direction.  
   
   
       9 . The grinding, polishing or paring machine according to  claim 2 , wherein the rotor is wedge-shaped.
