Embodiment Construction

[0017] The polishing machine shown here with only the parts considered here has a cylindrical rotor 1 equipped with conventional grinding tools 18 , eg cams. In the region where the polishing tool is located, the rotor 1 is enclosed by an octagonal screen 2 comprising two screen plates 3 and 4 . The screen 2 is in turn enclosed by a two-part perforated basket 5 in the form of a sheet jacket comprising two half-shells. The screen plates 3, 4 and the perforated basket 5 are connected to the self-supporting unit by threaded connections 6 and retaining sleeves, which are sealed at the surface with the end plates 7, 8 . A uniform narrow gap 9 is located between the sieve 2 and the perforated basket, thus creating a uniform and high air velocity which allows only a slight tendency for the ground powder to settle.

[0018] The half-shells of the perforated basket 5 have short, inwardly projecting ribs 10, which are advantageously provided with plug-in protrusions. The half-shells o...

Abstract

The invention relates to a polishing machine for rice or other cereals, comprising a perforated basket (5) that is embodied in a simplified manner. Said perforated basket (5) is provided with two curved walls in the form of half-shells with ribs (10) that protrude towards the interior. Preferably, both half-shells are connected to a split sieve (2) by means of screws and spacing elements so as to form a supporting perforated basket (5).

Description

technical field [0001] The present invention relates to polishers, and in particular to polishers or grinders for polishing or grinding paddy, even wheat, and the like. Background technique [0002] Polishers or grinders for rice or other grains with grinding or polishing rotors arranged horizontally or vertically are known in the art. For example, patent publications EP-A-699478 or EP-A-646414 disclose machines with vertically arranged rotors housing grinding or polishing tools. The rotor and tool are spaced apart and enclosed by a screen which in turn is housed in a perforated basket. The perforated basket is enclosed by a housing so that the grinding or polishing product cannot escape freely. The housing can be a full sleeve, or have an opening for a viewing window. Furthermore, the rotor can be configured as a hollow shaft with smaller openings in the area where the tool is located, to supply air and / or moist air and / or water into the treatment area. In a similar man...
