On October 31, the "Food Conservation Action Plan" issued by the Central Office and the State Council was officially released to the public. Food saving and detrimental losses have attracted great attention from the entire society. Dr. Stephen Covey, who was selected as the "25 People Who Influenced the Process of American History," once said, "One thing is certain: if we continue to do what we are doing, we will continue to reap what we are harvesting." What we are now facing is not the question of whether to change, but the question of how to change. In this issue of "Entering the Cloud Vision of Quality Sorting", let us walk into the hometown of China's ginkgo biloba Guanyitong Food Processing Co., Ltd., Nanxiong City, Guangdong Province, focusing on the problems and challenges faced by the appropriate processing of rice hulling section and the reduction of grains. , Experience the color sorting plan and contribution brought by the quality sorting 6S equipment for our moderate processing, food saving and loss reduction.

We know that the national standards for appropriate processing stipulate that the content of broken rice in the hulling section of rice processing: early indica rice ≤ 5%, late indica rice and japonica (glutinous) rice ≤ 2%. However, taking indica rice as an example, according to the survey, even the low level of conventional broken rice, the broken rice content in many rice enterprises is far more than 5%, usually around 10%, and many varieties are easy to be broken. The content of broken rice from the bottoms is sometimes astonishingly up to about 17%. The crushing increase of the rice hulling section has even exceeded 50% of the total crushing increase of the entire rice milling process. Of course, we know that the reasons behind the hulling and crushing problem in the hulling section are very complicated. There are problems with the hulling machine itself, as well as the problem of raw materials. In fact, there is a very critical factor that comes from the separation process of the rice hulling. The issue of brown rice content. The re-husking material should contain as little brown rice as possible, otherwise it will not only cause a substantial increase in the roughness and waist burst rate during the hulling process, which will greatly affect the rice yield, but also affect the output, glue consumption and power consumption of the hulling machine . At present, the technical level, quality level and even intelligence level of both foreign and domestic brands of rice hulling machines have been greatly improved, and the hulling performance and roughness control level of rice hulling have also been greatly improved. In this context, the problem of too much brown rice in the re-husked material has become a problem that we must not despise or ignore.

According to the country's relevant technical specifications and procedures for rice processing, the brown rice in the rice hulls does not exceed 10%. However, the actual situation is not the case. According to the survey, the proportion of brown rice in the re-husked material of most rice mills in the hulling section of the country is far more than 10%, and most of them are in the range of 20-70%. Therefore, even many factories are concerned and Certain control measures have been taken, such as adjusting the ratio of the gravity husked rice sieve, the ratio of the raw sieve and the brown rice product to the finished product, or adding a special gravity husker sieve for the treatment of the husked raw material, but either it cannot effectively solve the back hustle The percentage of brown rice in the raw material is either to reduce the quality of the finished brown rice and the quality of the brown rice mixture returned to the original sieve, thereby affecting the overall operating quality level of the hulling section. Of course, in accordance with the previous traditional rice processing requirements and specifications, under the condition of reasonable control of the hulling rate of the hulling machine, the percentage of brown rice contained in the re-husked material can be controlled to a certain extent. A certain level. At present, with the continuous advancement and development of rice hulling technology and the popularization of rice drying, the level of rice hulling rate in the hulling process has been greatly improved, which has brought new issues and challenges to the entire hulling section-whether to continue to persist in the end to control the hulling rate to a certain level to maintain the overall operation of the hulling section, or to innovate the model at a higher level, and promote the innovative development of the process and equipment of the hulling section.
