The invention relates to a processing method of rice powder and belongs to the technical field of production of products. The processing method includes the steps of mechanical sorting, color separation, hulling, husked rice separation, cryogenic grinding, high-pressure sterilization, drying and packaging. The processing method has the advantage that the color, aroma and taste of the product and property of active components are kept constant.
Description
Technical field
The present invention relates to a kind of processing method of rice powder, belong to the preparing technical field of product.
Background technology
According to the applicant understood, there is following problem in existing rice powder processing:
1. under existing rice normal temperature in toughness, be difficult to pulverize, can not keep the look of product, perfume (or spice),
The character of taste and active material is constant;
2. the bulk material mobility of rice powder made of existing rice is bad, and size distribution is poor,
Ensure that the fine degree of product is wanting in;
3. existing rice when ambient ground because of denaturalization phenomenon that heating, oxidation etc. cause;
4. can there are smell effusion, dust explosion, noise etc. when pulverizing in existing rice;
5., there is the denaturalization phenomenon because heating, oxidation etc. cause in the sterilizing processing of existing rice;
6. existing rice is when adopting low temperature drying, and produce discontinuous, the cycle is long, produces effect
Rate is low.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of processing method of the rice powder keeping the character of the color of product and active material constant.
The present invention is the technical scheme solving the problems of the technologies described above proposition:
A processing method for rice powder, comprises the following steps:
(1) machine choosing: according to the granularity requirements of product, selects the screen cloth of dimension to screen rice, carries out magnetic separation simultaneously, removing metal object, powder and weeds;
(2) look choosing: remove the heterochromatic grain that preceding working procedure stays;
(3) shell: according to the granularity requirements of product, use the rice huller rice machine of dimension to shell to rice, husking yield >80%;
(4) the rough separation of paddy: use unhulled rice that grain separating machine removal preceding working procedure stays, separation rate is more than 99%;
(5) Freezing smashing: the rice after rough for paddy separation is put into Freezing smashing device and carries out Freezing smashing, cold-producing medium adopts liquid nitrogen, controls cryogenic temperature-100 DEG C, rice is ground into rice powder;
(6) autoclaving: the rice powder after Freezing smashing is put into high-pressure installation and carries out autoclaving, keep the temperature in high-pressure installation to be 20 ~ 40 DEG C, the dwell time is 5 ~ 15min, and pressure is 300 ~ 500MPa;
(7) dry: collect the rice powder after autoclaving, and put into vacuum freeze dryer, control temperature is-80 DEG C, and vacuum is 133 × 10
-3mBar, drying time 2 ~ 4h, moisture≤7.0% in raw material;
(8) pack: by dried rice powder through carrying out packing, sealing after the assay was approved.
The present invention adopts the beneficial effect of technique scheme to be:
1) applicant's repetition test and further investigation, by adopting Freezing smashing and autoclaving, Freezing smashing not only can keep the character of the color of milling product and active material constant, and has incomparable advantage in the fine degree of guarantee product; Ultra high pressure treatment is a physical process substantially, adopts liquid medium process, have pressure uniform transmission, instantaneous, efficient, consume energy low, pollute few, to advantages such as the low molecular compounds such as vitamin, pigment and flavor substance have no significant effect;
2) by adopting Freezing smashing, controlling cryogenic temperature-100 DEG C, rice being ground into rice powder, can utilize the black brittleness of material, namely material is with the reduction of temperature, and its hardness and fragility increase, and plasticity and toughness reduce, just can be pulverized by a very little power under sharp freezing state;
3) in rice fast cooling process, the uneven contraction in inner each position can be caused and produce internal stress, under the effect of this stress, the inner weak part of rice produces micro-crack and also causes the adhesion of interior tissue to reduce, and under outside low-force, thus just makes underbead crack expand rapidly and broken;
4) when rice is freezing, moisture internally freezes from surface, and the obstruction that the freezing expansion of internal moisture is subject to outside frozen crust forms inside pressure, rice tissue is made to produce explosion, time freezing, the dissolved gas composition in rice liquid phase can expand hundreds of times, and spalling degree is higher, the loss of body fluid: temperature raises, the ice crystal freezed in rice dissolves, and due to rice disorganization, forms drop and flows out, concentrated and moisture evaporates: non-frozen fraction concentration increases, and the distillation of ice causes surface moisture to evaporate;
5) autoclaving is adopted, can non-covalent bond in the mycoprotein of destroy microorganisms, as hydrogen bond, disulfide bond and ionic bond etc., the higher structure of protein is destroyed, thus cause solidifying and the inactivation of enzyme of protein; Super-pressure also can cause somatic cells film rupture, makes endobacillary chemical constituent produce the various kinds of cell damages such as outflow; Can also affect copying of the inhereditary materials such as DNA, the result of these combined factors effects result in the death of microorganism, avoids the change of high temperature to the color of product and the character of active material.
The improvement of technique scheme is: be also provided with after described (8) step
Artificial selective examination: the requirement that the moisture content of rice powder, microorganism and client specify is tested;
Rice powder warehouse-in after selective examination is deposited: rice powder storage temperature≤12 DEG C, relative humidity≤70%, warehouse for finished product need clean, drying, health, directly not expose to sunlight, line identifier of going forward side by side.
The improvement of technique scheme is: described rice powder is long-grained nonglutinous rice powder, japonica rice Fen Huo Nuo rice powder.
