Abstract
The invention relates to a grinding machine for cereal grains, for example of rice, having a grinding tool. The grinding tool (2) has segments (5, 6) with vertically arranged air-outlet slots (3).
Description
Technical field
The present invention relates to a kind of grinder that is used to grind or polish cereal, be particularly useful for the grinding of the grain of rice.
Background technology
The grinding rotor (grinding rotor) that is used for handling the grinder of cereal is being known in the art.For example, patent publication us DE-OS 2640870 has described a kind of grain polisher with polishing rotor, and this polishing rotor is configured to contrary frustoconical, and towards the bottom constriction, and it is encapsulated by the porose tube of infundibulate to polish rotor.In addition, for example, patent publication us EP-A-699478 or EP-A-646414 disclose the machine of the rotor with vertical arrangement, and wherein said rotor holds grinding or polishing tool.Rotor and instrument are sealed by screen cloth mode at a certain distance, and screen cloth is maintained in the porose basket conversely.Porose basket is by shell encapsulated, so that avoid grinding or polished product to leave uncontrollably.Housing can comprise hard sheath or have the hole that is used for observation window.Rotor also can be constructed to the axle of hollow, and has less hole in the zone at instrument place, so that air and/or moisture and/or water enter the processing district.In the same way, the air slots on the axle of hollow also can directly dispose to polishing tool, for example with the form of cam, and is additionally provided with active surface (active surface) (US-PS4829783).Air passes polishing material and screen cloth, and the powder that has ground siphon from polishing material is come out and transported.
Rotor also can be provided with the instrument of combination, for example shells and polishing tool, as describing in patent publication us EP-A-427504.
For the powder of removing the grinding of leaving the screen cloth slit or the powder ash of polishing, the air that the flip cover that must often make progress is sent into relaying.The shortcoming here is, there is the rib that traverses air-flow usually in porose basket, air transmitted housing very big apart from the part, and the flow velocity of the air of flowing through is less in these zones.Horizontal web also can produce the turbulent flow (leeward turbulence) of lee face.
The production that has than the axle of the hollow of porous is arm and a leg, and because the higher pressure loss can appear in the aperture cross section, causes the air throughput to reduce and/or the more powerful air blast of needs.
At the machine that cereal cleans and grinds that is used for according to patent publication us JP-A-06327989, rotor is equipped with a plurality of milling tools with profile of tooth section.Porose tube is provided with the profile of tooth object, thereby the working region is " it " font.Because the pillar (rock) of top side also is a profile of tooth, so the feed zone of working region also is configured to the annular space of downward constriction.Yet the slope is shorter, and allows only a small amount of cereal to enter feed zone simultaneously, and seals the lower portion that wearing and tearing on the sieve substantially exceed the working region.
Summary of the invention
The objective of the invention is to develop a kind of grinder that is used to grind or polish cereal, it does not have the shortcoming of above-mentioned prior art, and makes around air can be evenly distributed to during the rotation of polishing tool.
Especially, can reach uniform speed air flow between screen cloth and the extraneous air conduction housing on the one hand, and more cost effective on the other hand supply air, with constant correlation between realization air capacity and the cross section, and constant flow velocity.
Claimed feature of the present invention can realize above-mentioned purpose.Milling tool is parts or multisection type parts, and has the air discharge slit of vertical setting.Screen cloth and seal between the airhood of screen cloth and have an optimal distance is so that realize constant correlation between air capacity and cross section.
Distance between screen cloth and the sheath body is selected in such a way, promptly provides gap (nip) as far as possible uniformly, to guarantee uniform air velocity.
Other embodiment provides the zone with another cross section that is used for very big air capacity and has had the zone of the narrower cross section that is used for less air capacity, and this has caused being used to discharge the eccentric space at abrasive dust end (the screen cloth outside).
As selection, milling tool also can be set to vertical grinding band or have the grinding section of airless space.
Description of drawings
Based on accompanying drawing the present invention has been described in further detail in an embodiment below.Accompanying drawing shows:
Fig. 1: the partial view of the rotor structure of grain of rice grinder;
Fig. 2: porose basket;
Fig. 3: the cutaway view of the part of milling tool;
Fig. 4: the cutaway view of sealing the airhood of porose basket.
The specific embodiment
A kind of grinder (being not represented for clarity), that for example describes among the applicant's the patent application document DE-A-10341223 is the sort of, the grinding rotor 1 with vertical layout, its armature spindle 4 supportings have the milling tool 2 of section 5,6 and feed screw 7.It is conical that first section 6 after feed screw 7 is.Milling tool 2 or section 5,6 have vertical air vent channels 3.
Except having section 5,6, milling tool 2 also can be designed to parts.
Milling tool 2 protects by porose basket 8 bags, and wherein said porose basket has the sieve plate (not shown), and it has the cross rib of being convenient to flow.
Screen cloth and porose basket 8 are sealed by airhood 9.Zone with wide cross-sectional 9 is used for big air capacity, and the zone with narrower cross section 10 is used for little air capacity, and this just makes and is used to discharge the eccentric space at abrasive dust end in the generation of the outside of porose basket 8.
