Horizontal grinding type grain milling machine

Abstract

This horizontal grinding type grain milling machine is capable of equalizing an internal pressure inside a polishing chamber, preventing uneven rice polishing when a low degree of polishing is required, and preventing the occurrence of broken rice when a high degree of polishing is required. The horizontal grinding type grain milling machine is configured in such a way that: a grinding roll is axially fitted to a main shaft provided with freedom to rotate inside a bran removal and polishing cylinder; and one end of the polishing chamber, a main part of which is between the bran removal and polishing cylinder and the grinding roll, communicates with a grain supply unit, and the other end thereof communicates with a grain discharge unit. In the horizontal grinding type grain milling machine,a convex helical blade for transferring grain from the grain supply unit to the grain discharge unit is fixed to an inner peripheral surface of the bran removal and polishing cylinder, and a polishing chamber resistance body which, by projecting toward the polishing chamber side, limits the movement of the grain that is moving due to the rotation of the grinding roll, is provided in the bran removal and polishing cylinder.

Description

technical field [0001] The invention relates to a horizontal grinding mill. Background technique [0002] As a conventional horizontal grinding type rice mill, there are rice mills described in Patent Documents 1 to 6. [0003] In the grain milling machines described in these patent documents 1 to 6, a part or the entire inner surface of the porous wall milling cylinder formed in the milling chamber by a built-in horizontal axis grinding roller is provided with a helix in an inclined shape, so that the grains can be wound while winding. The rotation direction of the above-mentioned horizontal axis grinding roller is twisted, while being guided and fed forward. [0004] Thereby, the following effect can be obtained: the grains supplied to the milling chamber are slowly guided along the inclined edge of the spiral, so even if it is a long-stroke milling chamber, a powerful grain feeding rotor is not used, and the The spiral bar located on the side of the whitening cylinder w...

Problems solved by technology

[0006] Therefore, when it is desired to process grains with a low degree of grinding, since it is a horizontal axis type, the filling degree of the upper side of the grinding chamber is low. On the other hand, when it is desired to process grains with a high degree of grinding, It is easy to generate excess friction resistance near the valley discharge mouth, and even cause the rise of valley temperature and the generation of mechanical broken rice
