3, convenient rice of the bitter buckwheat of disclosed patent CN03138822.1 and production method are with duck wheat expanded back shelling.
No matter be adopt frying, steam, expanded, all be earlier with shelling again after the duck wheat slaking, the seed of Radix Et Rhizoma Fagopyri Tatarici of slaking that obtains like this, its nutrition all receives breakage to a certain degree, and shelling back whole grain rate is not high.
Summary of the invention
The present invention is in order to solve existing Fagopyrum tataricum hulling method has mostly changed seed of Radix Et Rhizoma Fagopyri Tatarici because of curing step original nutritional labeling and characteristic; And the not high problem of whole grain rate; A kind of Fagopyrum tataricum hulling method is provided; This method can keep duck wheat original nutrition composition, and can obtain the intact form seed of Radix Et Rhizoma Fagopyri Tatarici more than 90%.
The present invention adopts following technical scheme to realize: Fagopyrum tataricum hulling method, carry out 1, to the dedusting of raw material duck wheat, removal of impurities according to following operation; 2, soak with clear water, 3, put into special container, send in the industrial micro-wave oven and heat; Heating and temperature control is less than 65 ℃; 4, send into hulling device and shell, 5, separate the duck wheat shell thrown off, 6, screening or gravity type paddy separator sub-elect seed of Radix Et Rhizoma Fagopyri Tatarici through screening, selection by winnowing.Inner characteristic of the present invention is that heating using microwave has been used for Fagopyrum tataricum hulling.Adopt first clear water to soak seed of Radix Et Rhizoma Fagopyri Tatarici is expanded, impel the most advanced and sophisticated opening of shell, the applied microwave quick dewatering drying makes its further broken shell again, then can easily adopt the hulling device shelling.Microwave dehydration is a mechanism of utilizing dielectric drying, with common drying very big difference is arranged, and common moisture when dry begins from surface evaporation; Inner moisture slowly diffuses to the surface; Heat energy is delivered to material inside by the outside, so need very high external temperature usually, makes the duck wheat slaking.In the dielectric drying process, material inside and outside produces heat simultaneously rapidly, and transmitting motive force mainly is the inner formed barometric gradient of steam that produces rapidly of material.Begin very wetly like material, the material pressure inside raises very fast, and then liquid is squeezed under the effect of barometric gradient from material.Initial wet content is high more, and barometric gradient divides the influence of getting rid of also big more to wet, and a kind of " pump " effect is also promptly arranged, and orders about liquid, gas and flows to the surface rapidly.Utilize this principle, adopt microwave, make in the duck wheat rapidly " pump " to go out liquid and steam state mix moisture, but impel benevolence and shell effectively to separate also broken shell, so just be very beneficial for next step shelling of duck wheat.During microwave drying, temperature is controlled at less than 65 ℃, can guarantee that duck wheat original nutrition composition is not destroyed; And can make seed of Radix Et Rhizoma Fagopyri Tatarici have certain anti-squeezing to roll performance and help improving whole grain rate, its reason possibly be due to the sucrose, glucose absorption microwave softened, dry back in " benevolence ".The dry advantage of microwave dehydration has: energy effective utilization, do not have destructive, other volatile materials migration amounts less, stepless action, energy tend to be applied to the humid region, dry rapidly, the time can shorten 50% or more, uniform drying.
The present invention has provided a kind of brand-new Fagopyrum tataricum hulling method; This method innovation property ground is used for Fagopyrum tataricum hulling with heating using microwave; Utilize the shelling of the characteristic realization duck wheat of heating using microwave; Avoid the slaking of duck wheat in the shelling process simultaneously, can keep duck wheat original nutrition composition, and can obtain the intact form seed of Radix Et Rhizoma Fagopyri Tatarici more than 90%.
The specific embodiment
Fagopyrum tataricum hulling method carries out according to following operation, and 1, to the dedusting of raw material duck wheat, removal of impurities; 2, soak with clear water, 3, put into special container, send in the industrial micro-wave oven and heat; Heating and temperature control is less than 65 ℃ (as 64 ℃, 60 ℃, 55 ℃, 50 ℃, 45 ℃, 40 ℃ etc.); 4, send into hulling device and shell, 5, separate the duck wheat shell thrown off, 6, screening or gravity type paddy separator sub-elect seed of Radix Et Rhizoma Fagopyri Tatarici through screening, selection by winnowing.During practical operation, the isolated band shell of step 6 duck wheat returns step 4.
The time of heating using microwave is relevant with the shop layer thickness of duck wheat in container, the temperature of heating using microwave (less than 65 ℃) etc., and the shop layer is thick more, temperature is low more, and the time of heating using microwave is long more, and the shop layer is thin more, temperature is high more, and the time of heating using microwave is short more.Under less than 65 ℃ a certain specified temp (it is limited to the minimum heating-up temperature that industrial micro-wave oven can be provided with down), obviously microwave heating time is too short, can't realize that the shelling of duck wheat or husking yield are low excessively; As long as microwave heating temperature is less than 65 ℃, and therefore the long nutritional labeling that more also can not destroy duck wheat of time in practical operation, can have sufficient microwave heating time, makes duck wheat fully dry; Say that from the angle of pure shelling fully dry duck wheat is more conducive to follow-up shelling.But too dry duck wheat (general water content is lower than 5%), seed of Radix Et Rhizoma Fagopyri Tatarici has bigger fragility, and is damaged easily in follow-up shelling operation, and influences whole grain rate.For balance shelling and whole grain rate, make this method more perfect, during practical implementation; Duck wheat is put into special container with uniform thickness 1-5cm (optional 1cm, 2cm, 3cm, 4cm, 5cm etc.); Microwave heating time is controlled at 8-20 minute (according to the difference of thickness, selecting in this time range), and the duck wheat moisture after the oven dry can be controlled in 15%-18% like this; Both can guarantee duck wheat broken shell and follow-up shelling, can guarantee higher whole grain rate again.During concrete operations, the time that clear water soaks does not have strict restriction, can as prior art, soak several hours.But because the method for the invention has adopted heating using microwave, so the clear water soak time can shorten greatly, clear water soaks and got final product in 30-50 minute, can shorten process time like this; In order further to improve the shelling effect, the soaked in water temperature control is at 10 ℃-30 ℃.Hulling device can select for use hulling machine or differential to rubber roll machine or other feasible hulling device.For further improving the shelling effect, increase an operation in step 2, between 3, i.e. duck wheat after soaking; Behind the screen cloth drainage; Moistened cool 1-5 hour, and treated that no obvious moisture is put into special container again on the duck wheat shell to send into industrial micro-wave oven, can shorten microwave heating time like this.Described industrial micro-wave oven has 915MHz and two kinds of operating frequencies of 2450MHz, the thicker 915MHz that selects for use earlier when higher with moisture of shop layer.
