Description

A kind of apparatus of selecting rice color

Technical field

This utility model relates to a kind of apparatus of selecting rice color.

Background technology

The nucleus equipment of selecting rice color technology is color selector, and its operation principle is：Selected rice passes through electromagnetism by feed hopper Ferrum oscillating feeder, is dispensed in each sorting passage and drops downward into photoelectric detector.The spectrum that the normal high-quality grain of rice determines Frequency band is transfused in colour table, and chromoplastid band has difference with it.The grain of rice is reflected in electronics to the reflection of light and radiation shield Colorimetric in visor, such as color are variant, and through opto-electronic conversion computer is entered, and signal to amplifier amplifies.If meeting color tablets, This signal exceedes the preset value of automatic control level, and its signal is stored.Time delayed signal time difference is being produced just by storage portion signal Well time difference between visor and ejector is dropped through equal to the selected grain of rice, when the coloured grain of rice reaches injector locations, immediately Drive steam jet atomizer project the container made of bamboo, wicker, ratten, etc. speed air-flow, chromoplastid is blown out and is sent in chromoplastid discharge bucket, and " homogeneity " grain of rice after It is continuous to fall to entering " homogeneity " rice discharge bucket.Because high speed injection and the stopping of jet-impingement system are to replace moment to send out Raw, the selected grain of rice is easy to pass through, and through color selector cleaning and Purification, its condition just can reach predetermined color choosing and requires rice.

As light harvesting, electricity, gas, machine in the high-tech product of one, color selector is to installation, use environment and supporting pressure The requirement of contracting air system, purging system and regular maintenance and operant skill is very high, and its price is also costly.Enterprise should be said Use of the industry to color selector is very careful, but still has the efficacy exertion of quite a few color selector in practice process not Ideal, is exactly process matching sex chromosome mosaicism the reason for one of them is important.Bypass color selector install and use environment, regular maintenance and The requirement of the aspects such as the use technical ability of operator, affects color to select the factor of technological effect mainly to have following several in rice processing Point：(1) bran-containing quantity of Raw Materials Rice.When more containing bran in Raw Materials Rice, in the case of moisture and proper temperature, when one section Between after color selector passage on easily fouling, affect the flowing of the grain of rice.In addition, the indoor dust concentration of sorting is too high, can affect The identification ability of photoelectric detector and the work of injection valve, so as to reduce precision of color separation.(2) the heterochromatic grain content of Raw Materials Rice. Typically require the calibration range of the heterochromatic grain content of Raw Materials Rice less than color selector, now precision of color separation, take out of than and yield Can be up to standard.And when heterochromatic grain content exceeds normal range, it is ensured that certain precision of color separation compares with taking out of, then must drop Low yield so that unit processing cost is greatly increased；Conversely, to reach output demand, then precision of color separation is necessarily reduced, and takes ratio out of Necessarily raise, so as to affect end product quality and rice milling yield.(3) temperature of Raw Materials Rice.After whitening through multiple passage and polishing Rice, due to its temperature be higher than normal meter Wen, such as immediately enter color selector, the chaff powder for easily making rice surface sticks to channel table Face, affects the proper flow of the grain of rice, reduces color and selects effect.(4) air source quality.Color selector sorting unit is to utilize pressure-air Abnormal rice kernel is blown out into normal orbit.The quality of pressure-air will affect color selector precision and take ratio out of.Source of the gas requires oil-free, nothing Water, dustless, dry and pressure stability, otherwise easily block gas circuit and injection valve, affect the sensitivity level of injection valve events, and easily Defective nozzle.

Utility model content

The purpose of this utility model is to solve the problems, such as above-mentioned prior art, there is provided raising color can drop in one kind Select the apparatus of selecting rice color of effect.

In order to solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：A kind of apparatus of selecting rice color, including entering Hopper, oscillating feeder, chute, photoelectric detector, steam jet atomizer, main discharge gate, chromoplastid discharge gate and frame, it is described The back side of chute is provided with circulating cooling water pipe.

The beneficial effect of above-mentioned technical proposal is：Because the back side of chute is provided with circulating cooling water pipe, so can drop The temperature of the low grain of rice, it is to avoid the chaff powder of rice surface sticks to chute surface, so as to ensure that the grain of rice is normal in chute Flowing, is favorably improved color and selects effect.

The further technical scheme of this utility model is：Dust exhaust apparatus is housed in the frame.Dust exhaust apparatus one side energy The indoor dust of sorting is enough siphoned away, in order to avoid affecting the identification ability of photoelectric detector, on the other hand the reduction grain of rice can be also played The effect of temperature, so as to improve color effect is selected.

Further, separated by one piece of dividing plate between the main discharge gate and the chromoplastid discharge gate, it is described every Plate includes being located at the fixed plate of bottom and the portable plate on top, and fixed plate is hinged with portable plate, and portable plate can left-right rotation.Adopt This structure is used, the aperture position of main discharge gate and chromoplastid discharge gate can be carried out according to the rice of different cultivars or rank Adjust, it is ensured that the different grain of rices can accurately fall into the discharge gate of correlation.

Preferably, the section of the chute is " V " shape or " u "-shaped.

Preferably, the chute is made up of stainless steel material.
