Abstract

The invention discloses a processing technology of wash-free rice, in particular to the technical field of wash-free rice processing, which comprises the following processing processes: s1, removing impurities: removing dust, stones and fallen husks in original grains; s2, pressurization: uniformly laying the grains subjected to impurity removal in the step S1, and applying pressure for separating grains from shells to the grains; s3, rice hulling: introducing the grains pressurized in the step S2 into a rice hulling device, and fully hulling the grains into rice grains; s4, drying: the rice kernels dehulled in S3 were thoroughly dried. In the processing process of drying, water filtering and screening the grains, the husk and the grains are easier to separate in the drying and water filtering processes of the grains, so that the cleanliness of the grains is further ensured.

Description

Processing technology of washing-free rice

Technical Field

The invention relates to the technical field of washing-free rice processing, in particular to a washing-free rice processing technology.

Background

The wash-free rice is also called wash-free rice, which refers to rice that can be directly cooked without washing, and is only established according to local standards and enterprise standards and various indexes of special rice.

The existing washing-free rice processing technology is complex, damages the rice grains to a certain degree, and causes the rice grains to have poor water absorption during cooking, easy agglomeration and poor taste.

Disclosure of Invention

In order to solve the technical problems, the invention provides a processing technology of wash-free rice, which comprises the following processing processes:

s1, removing impurities: removing dust, stones and fallen husks in original grains; s2, pressurization: uniformly laying the grains subjected to impurity removal in the step S1, and applying pressure for separating grains from shells to the grains; s3, rice hulling: introducing the grains pressurized in the step S2 into a rice hulling device, and fully hulling the grains into rice grains; s4, drying: fully drying the rice kernels hulled in S3; s5, water filtration: filtering the rice grains dried in the step S3 with clear water to remove dust and impurities on the surfaces of the rice grains; s6, screening: and (4) controlling water and screening the rice grains after water filtration in the step (S5) to fully screen off the chaff and impurities outside the rice grains.

In a preferred embodiment, the water-strained rice kernels of S5 are re-dried via S4.

In a preferred embodiment, the rice grains are sterilized by a sterilization process after the screening of the rice grains in the S6 is finished, so that the rice grains are free from washing and can be directly eaten.

In a preferred embodiment, the finished wash-free rice is obtained by quantitative vacuum packaging through a packaging device after the rice grains are sterilized.

The invention has the technical effects and advantages that:

in addition, through the processing technology of drying firstly and then filtering water, the processed rice grains have better water absorption performance, are not easy to agglomerate in the cooking process and have good taste.

FIG. 1 is a schematic view of the overall process of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

The processing technology of the washing-free rice as shown in figure 1 comprises the following steps:

the first embodiment is as follows:

the method comprises the following processing steps:

s1, removing impurities: removing dust, stones and fallen husks in original grains; s2, pressurization: uniformly laying the grains subjected to impurity removal in the step S1, and applying pressure for separating grains from shells to the grains; s3, rice hulling: introducing the grains pressurized in the step S2 into a rice hulling device, and fully hulling the grains into rice grains; s4, drying: fully drying the rice kernels hulled in S3; s5, water filtration: filtering the rice grains dried in the step S3 with clear water to remove dust and impurities on the surfaces of the rice grains; s6, screening: controlling water and screening the rice grains subjected to water filtration in the step S5 to fully screen off husks and impurities outside the rice grains; in addition, through the processing technology of drying and then filtering water, the processed rice grains have better water absorption performance, are not easy to form lumps in the cooking process and have good taste.

Example two:

the method comprises the following processing steps:

s1, removing impurities: removing dust, stones and fallen husks in original grains; s2, pressurization: uniformly laying the grains subjected to impurity removal in the step S1, and applying pressure for separating grains from shells to the grains; s3, rice hulling: introducing the grains pressurized in the step S2 into a rice hulling device, and fully hulling the grains into rice grains; s4, drying: fully drying the rice kernels hulled in S3; s5, water filtration: filtering the rice grains dried in the step S3 with clear water to remove dust and impurities on the surfaces of the rice grains; s6, screening: controlling water in the rice grains subjected to water filtration in the step S5, screening to ensure that rice husks and impurities outside the rice grains are sufficiently screened, and drying the rice grains subjected to water filtration in the step S5 through the step S4; the difference between this embodiment and the first embodiment is that after the drying-water filtering process, the rice grains are dried again by S4 and then treated by the sieving process, so that the chaff and the grains are sufficiently separated, and while the cleanliness of the grains is further ensured, the processed rice grains have better water absorption performance, are not easy to form lumps in the cooking process and have excellent taste by the processing process of drying first, filtering water and drying second.

And S6, performing a sterilization process after the screening of the rice grains is finished, fully sterilizing the rice grains to ensure that the rice grains are free from washing and can be directly put into eating, finally performing quantitative vacuum packaging on the sterilized rice grains by packaging equipment to obtain finished product free from washing rice, and performing sterilization and vacuum packaging on the free from washing rice after the processing of the free from washing rice is finished, thereby ensuring the sanitation and safety of the free from washing rice.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art and related arts based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
