Problems solved by technology

[0002] At present, in the rice processing technology, raw grains are basically harvested by machines, and agricultural products no longer carry out excessive removal of impurities and drying to remove moisture from the grains, resulting in easy mixing of raw grains, cross-contamination, more and more impurities, and moisture. The content is very high and uneven, which brings great difficulties to rice processing
Moreover, after husking and milling, the temperature of the rice is relatively high. If it is directly sent to the polishing machine for polishing, firstly, the appearance is not good, secondly, the broken rice rate is high, and the rice yield rate is low. , the shelf life is short, only one to four months
If the rice is naturally cooled by stacking and bagging, it is time-consuming and labor-intensive, with low work efficiency and high cost; or using cooling rice boxes, fluidized beds, air coolers and other equipment to cool the rice, the cooling time of the rice is short, the temperature is cooled quickly, and the rice grains are easy to burst and break. Rice rate is also high
In addition, people's consumption concepts are constantly changing, and new requirements are constantly being put forward for the external senses, taste and therapeutic effects of rice. Obviously, rice processed from a single raw grain variety cannot meet people's needs.

Embodiment 1

[0025] An improved fragrant rice processing and production method, comprising the steps of:

[0026] (1) After the rice is harvested, it is threshed by a thresher, and the rice is placed in a plastic greenhouse for ventilation and drying. The internal temperature of the greenhouse is heated and regulated by a hot air system composed of multiple hot air fans. The internal temperature of the greenhouse is maintained at 35°C-45°C. Within the range of ℃, the relative humidity in the greenhouse is maintained at 10%-15%; after the rice is dried, the moisture content of the rice is reduced to 15%-18%;

[0027] (2) After the rice is dried, the impurities contained in the rice are removed and separated by the impurity remover; the metal impurities and gravel particles are removed by the magnetic separator and the stone remover; after the rice impurities are cleaned, the rice is stored in In the storage bin, the internal temperature of the storage bin is controlled within the range of 5...

Embodiment 2

[0036] As a preferred solution of the present invention, the aperture of the sack or the net frame is 0.2mm-0.3mm; the shape of the net frame is a square or circular groove structure; the packaging process of the fragrant rice adopts a nitrogen-filled packaging method, The rice is packaged according to the quality standards of 10Kg, 20Kg, and 50Kg; the polishing process is carried out in a polishing machine, and the color sorting and grading processes are screened by a color sorter and a sorter respectively, so as to obtain white rice particles of different grades .

[0037] The fragrant rice of the present invention is through statistics and calculation, finds that under the sealed storage state of fragrant rice, its shelf life is 13 months, has played very good shelf life effect with respect to the 6 months shelf life of national standard; Simultaneously, broken The mass ratio of rice is reduced to 13%, compared with the mass ratio of 15%-30% of broken rice in the traditiona...

Abstract

The invention relates to the technical field of rice processing, in particular to an improved fragrant rice processing and production method. On the one hand, impurities and water mixed in unhulled rice are effectively removed; the adhesion strength between rice grains and hulls of the unhulled rice is reduced through drying treatment, and the rice hulls fall off advantageously; the influence on the quality of the rice from the impurities can be avoided through the impurity removal treatment, and the rice processing quality is improved; through the earlier-stage processing, hull removal of the unhulled rice is more technological, reduction of broken rice is facilitated, and the proportion of the broken rice is reduced; on the other hand, the taste of the rice is effectively improved through treatment in a storage bin and fumigating treatment in a fumigating bin, and as traditional Chinese medicine raw materials like Eucommia ulmoides and Bletilla striata are included in fumigation materials, dietary therapy for people who eat the rice is facilitated; and in addition, the safety quality of the fragrant rice is improved and the expiration date is prolonged through sterilization treatment, package and storage in the later stage.

If it is directly sent to the polishing machine for polishing, firstly, the appearance is not good, secondly, the broken rice rate is high, and the rice yield rate is low. , The shelf life is short, only one to four months. If the natural cooling rice is piled and packaged, it is time-consuming and labor-intensive, with low work efficiency and high cost; or using cooling rice boxes, fluidized be...
