Rice processing edulcoration is with proportion destoner

Technical Field

The invention relates to the technical field of rice processing, in particular to a specific gravity stone removing machine for removing impurities in rice processing.

Background

The specific gravity stone remover is an impurity removing device which separates mineral substances from particulate materials (mainly, side-by-side stones and the like) by using the difference of the density and the suspension speed of the particulate materials (rice, brown rice, wheat and the like) and the mineral substances (mainly, the side-by-side stones and the like) and by means of mechanical wind power and a screen surface which reciprocates in a certain track. The device specifically comprises an absorption type specific gravity grading stone remover with double-layer sieve surfaces, an absorption type specific gravity stone remover with multiple stone removing sieve surfaces, a double-sieve surface absorption type specific gravity stone remover with crushing (coarse crushing, small crushing and the like) sieve surfaces (such as a grain coarse cleaning stone remover and the like), an absorption type and blowing type screening stone removing combined machine with large, medium and small impurity sieve surfaces, a circulating air specific gravity stone remover with a single-layer sieve surface, a circulating air specific gravity grading stone remover with double-layer sieve surfaces, a circulating air combined cleaning machine and the like.

The blowing type specific gravity stone remover works in a positive pressure state, so that raised dust is easy to generate, and certain influence is brought to the environmental sanitation of a workshop. If the operation is proper, the stone removing effect is comparable to that of a suction type specific gravity stone remover in the rice cleaning process section; in other process sections after the cleaning process, the blowing type specific gravity stone remover has a stone removing effect which is not the same as that of an absorbing type specific gravity stone remover and a circulating air specific gravity stone remover, and because air circularly flows in the blowing type specific gravity stone remover in a closed manner and is repeatedly utilized, dust is basically not blown out, the environmental sanitation of a workshop is not influenced, and dust removing facilities, an air net and the occupied space thereof can be correspondingly saved. But the particle size of the particle materials entering the circulating air specific gravity stone remover is basically consistent, and the materials are basically free from light impurities, small impurities and the like, otherwise, a filter screen, a stone removing screen surface and the like of the particle materials are easily blocked. Therefore, the application range of the circulating air specific gravity stoner has certain limitation.

Specific gravity destoner is when carrying out the edulcoration to rice, use vibrating motor to drive the vibration of stone sieve board usually, make building stones and rice separation, but when the volume of building stones is too big, cause the damage to removing the stone sieve board at the in-process of vibration easily, the influence is to the screening of building stones, the in-process of carrying out the edulcoration screening to the particulate matter simultaneously, the condition of jam appears in the punchhole of sieve easily, can lead to the screening effect decline of sieve when the punchhole is blockked up when more, for this reason we provide a specific gravity destoner for rice processing edulcoration.
