Abstract

The invention relates to a wheat grain hulling machine and a flouring method. The flouring method includes spraying the cleaned wheat grains with certain water, then feeding the wheat grains into the hulling machine for hulling, and flouring the wheat grains hulled. In this way, high-quality refined flour is achieved with high yield. The hulling machine is provided with an inner tapered corundum roller and an outer lining. The distance between the inner roller and the outer lining can be adjusted by an adjusting element of a spline spindle, so that wheat grain hulling effect is under control. The wheat grain hulling machine is convenient to operate, hulling rate can be adjusted according to actual needs, and power consumption is low.

Description

Wheat seed takes off peeling machine and milling method

The present invention relates to a kind of wheat seed first de-wheat bran milling method and for using the method and custom-designed wheat special peeling machine.

In wheat processing industry, traditional flouring technology is by after wheat cleaning, the wheat wetting that adds water, and directly enters flour mill, and whole wheat is ground.Through repeatedly grinding, screen repeatedly, removes wheat bran, obtained flour.Such milling method has following problem: because wheat seed endosperm by the suitcase of six layers of differing texture, and particularly outside seed coat, containing crude fibre and pigment, has certain intensity and toughness.So, endosperm and wheat bran mixed in together, repeatedly grinding, sieve, affecting pink colour and quality with regard to causing crude fibre matter and coloured cortex to be grinding in flour.Some countries in order to obtained high-quality flour, first by wheat cleaning wheat wetting, after grind step by step, progressively screen.But only make flour extraction be reduced to 65 percent.

The milling method of abrasive dust after the object of the invention is to provide a kind of wheat seed first to peel, to obtain the flour of high rate, high amount processed.

For the machinery that general cereal is peeled, usually adopt rice mill or peeling machine.Its primary structure on rotating spindle, fills a conical carborundum roller and cast iron overcoat forms fixed interval (FI), by opening large or turning down the import and export gate control decortication of grain.But, utilize above-mentioned machinery to carry out wheat debranner, because the gap of interior roller and iron overcoat can not regulate, and wheat peel in machine after can not go out machine in time, so flow is little, de-not scaling; Flow is large, a large amount of containing powder in bran, reduces flour extraction.Be difficult to control, its exfoliant effect is poor, consumes energy high.

The present invention realizes the milling method that wheat seed first peels, and provides a kind of special peeling machine of horizontal cone wheat of improvement, to improve the decortication efficiency of wheat, reduces power consumption.

The present invention be achieved in that wheat seed peeling flour method by wheat seed through cleaning after, when adding water wheat wetting, the water that another increasing is quantitative, after completing wheat wetting, add water after wheat wetting again, enter peeling machine to peel, the wheat core of decortication enters flour mill again, needs by it flour wearing into different brackets.Wheat thresher inlays a conical carborundum external bushing in cast iron overcoat, cast iron inner sleeve fills roller in a conical carborundum, spline spindle is equipped with regulating part, suitably regulates the spacing of the inside and outside roller of diamond dust to control exfoliant effect by regulating part.Wheat, by the concavo-convex friction on diamond dust external bushing, interior roller, is taken off skin.

Below in conjunction with drawings and Examples, wheat seed peeling flour method proposed by the invention and peeling machine thereof are described.

Fig. 1 is the profile of wheat thresher.

This wheat thresher is horizontal cone.It comprises a cast iron overcoat (1), a conical carborundum external bushing (3) is studded with in iron overcoat (1), such as: the long 400-600 millimeter of external bushing (3), diameter 200 millimeters, diameter at butt end 376 millimeters, thickness 18 millimeters, have a spline spindle (10), (10) are equipped with regulating part with main shaft.Regulating part comprises: dextrorotation cover handle (8), a trapezoid thread sleeve (9), a spring (7) and two spline steel bushings (2,6).A taper cast iron inner sleeve (5) is housed outside spline steel bushing (2,6), roller (4) in a conical carborundum is housed outside sleeve (5).Main shaft (10) rotating speed is that 800-960 per minute turns.

After wheat thresher running, wheat seed to be sent in diamond dust between roller (4) and external bushing (3) by auger.Trapezoid thread sleeve (9), spring (7) and spline steel bushing (2 is regulated by handle (8), 6), make roller in diamond dust (4) moving axially along spline spindle (10), regulate roller in diamond dust (4) and the spacing of external bushing (3), control wheat debranner effect.Wheat passes through the gap of diamond dust external bushing and roller, after taking off wheat bran, is separated by wheat bran through cyclone separator with wheat core.This machine is easy to operate, and peeling rate can regulate as required.As: platform output is the peeling machine of 1.5 tons per hour, and processing wheat power consumption per ton is 4-10 degree.

Wheat seed peeling flour method by clearing up, peel, three operations such as abrasive dust form.Wherein: cleaning process comprises sieve wheat machine, wheat washer, stone remover, permanent magnetic pulley, comparatively traditional handicraft eliminates wheat scourers, pursues and attacks machine and wipe wheat machine; Decortication operation comprises spraying machine, peeling machine; Abrasive dust operation comprises flour mill, sieving machine, comparatively traditional handicraft can save wheat-bran brushing machine, wheat flour detacher and first sieve.To produce the small processing factory of 30 tons of standard flours daily, the comparable traditional handicraft of this method saves equipment 4-6 platform, saves equipment investment ten to two 2 percent 15.

Wheat seed, after cleaning out, is adding water or is washing in wheat water transfer process, with reference to powder manufacturing apparatus, quantity, quality and flouring technology flow time, consumes moisture content situation, the another water increasing 0.5-0.9%.After carrying out wheat wetting, add a water again with spraying machine, amount of water is 0.2-0.6%, then wheat wetting 15-25 minute, after completing wheat wetting, enters peeling machine and peels, and enters first shelling thereupon and starts powder process.But the application 40-50 DEG C of water wheat wetting when northern China to grind wheat flour winter.The method increase abrasive dust efficiency, add flour kind, obtain high rate, high-quality refining flour.

To produce the little factory of 30 tons of standard flours daily, per diem process wheat 34.5 tons, if wheat is taken off the wheat bran of 6% before powder process, 2.07 tons of wheat brans just can be made no longer to reface, heavily sieve, can power saving 158 degree.This method can produce the flour of different brackets simultaneously.As: get final product production top grade powder 20%, top patents 20%, wheat core powder 23%, common flour 24%, paste layer powder 6%, wheat bran 6%, than the traditional handicraft of single production standard powder 85%, wheat bran 14%, can be country after every hundred kilograms of wheat processing and increase income 3.52 yuan more.
