Technical Field

The present invention relates to a food sorting apparatus.

Background

Granular foods such as flour, raw meal and the like; classifying according to the particle size; the traditional separation method is air separation, but the wind power is fixed during air separation, so that only one-time separation can be completed. After primary separation is finished, wind power is adjusted again, and secondary separation is carried out on the particles which are separated out through air separation, so that the powder particles are classified according to small, medium and large particle size types.

This way of sorting is cumbersome. For this reason, we have designed a food sorting apparatus that achieves one-time sorting.

Disclosure of Invention

The invention aims to provide food sorting equipment for realizing one-time sorting.

Preferably, an obliquely arranged discharging plate is arranged at the inner bottom of the lower box body, and the discharging plate is obliquely downward towards the discharging pipe; the setting of stripper can reduce the clout and remain.

Preferably, more than 3 rollers are annularly arranged at the bottom of the lower box body; the arrangement of the rollers is convenient for realizing the movement of the lower box body.

Preferably, a rubber folding pipe is arranged at the lower end of the upper box body, and the lower end of the folding pipe props against the lower box body; the arrangement of the folding pipe can keep the sealing performance between the upper box body and the lower box body; while maintaining the seal when the upper box vibrates.

Preferably, a material guide plate is arranged inside the upper box body, the material guide plate is correspondingly arranged below the feeding hopper, and a feed opening is formed between the material guide plate and the inner wall of the upper box body; the material guide plate can avoid the material entering through the feeding hopper to directly impact the metal screen downwards, meanwhile, the retention time of the material is prolonged, and fine powder particles are conveniently captured through negative pressure.

Preferably, a lifting lug is welded on the outer part of the upper box body; the setting of lug conveniently lifts by crane the upper box body with the help of electric block.

The invention has the beneficial effects that: the device collects and captures fine particles suspended in the lower box body after blanking under the action of the negative pressure fan to finish primary classification; the particles with relatively large particle size cannot be captured through negative pressure and then downwards contact the metal screen; the upper box body is driven to vibrate by the vibration motor; shaking off the powder particles on the metal screen to realize secondary separation; after secondary separation, the particles with medium particle size downwards pass through the metal screen, and the particles with larger particle size are intercepted by the metal screen; by the classification mode, the classification of the sizes of three kinds of particles, namely small particles, medium particles and large particles, can be completed at one time. Simple and convenient operation, and is suitable for popularization and use.
