The new IoT rice mill machine has further upgraded the traditional rice mill machine to provide consumers with fresh rice that is now sold and sold. Rice processing is post-processed, and the new rice sales form will solve the above problems. In the past, traditional rice mill machines were bulky and cumbersome, and most of them were only suitable for rice mills. The rice in the rice supply chain is in the front, and the rice that consumers can buy is less fresh. With the development of rice mill machine, the volume is getting smaller and smaller, and even a special rice mill has appeared.
However, because this rice mill machine cannot be separated from the human operation, the rice source has insufficient complex trust, the operating cost is too high, and the production efficiency is high. Too low, it is impossible to spread widely. Therefore, the application of the Internet of Things technology to the improvement of the rice mill makes it very valuable to create a new type of IoT rice mill. The new IoT rice mill is a key technology research and system development around the rice-retaining embryo technology and the rice traceability system, making it easy for the public to buy healthy and high-quality milled germ rice.
Rice's full process traceability technology: health starts from the source
Rice from the origin to the end of the consumer needs to go through many links, such as planting, harvesting, transportation, warehousing, sales and so on. Each link will have different participants, and each participant will handle the rice information differently. How to effectively integrate the rice traceability information and connect the information islands between the various links is the key to realize the traceability of the whole process of rice. In the construction of the rice traceable system, the query and search service based on the IoT identification management is used to identify the service providers such as the origin, transportation company, and storage company, according to the registered object identifier and the identifier of the addressable information server. Mapping relationships, obtaining and returning information to the addressable rice server to the identification query, and realizing the traceability of the whole process of rice.
Milling and retaining embryo technology: aligning with the international leading level
The germ rice is the part of the germ that retains the rice, and the other part is exactly the same rice as the white rice. The most important central part of rice is the germ. The so-called "bud" is the part that gives birth to a new life. Its scientific standard name should be called "remaining embryo rice", which is rice with a retention rate of more than 80%. At present, the average retention rate of the majority of rice mills in China is less than 60%, and very few can reach the retention rate of more than 80%. The new IoT rice mill machine improves the milling precision by reducing the sensing of the rice milling device, reduces the loss rate of the finished rice germ, and increases the embryo retention rate to 85%.
Transforming traditional communication modules: based on low-power WAN
Because the location of each device is not covered by the network coverage, the original 4G universal network module of the device is not suitable for all placement environments. When the signal is weak, the device may not work properly. In order to solve this problem, the original network module of the device is connected to the self-developed WiFi and Lora application. When the operator's network signal is not good, the low-power wide area network Lora module can be switched at any time for information transmission to ensure the normal operation of the device for 24 hours.
Dynamic weighing of finished rice: weight error is less than 6‰
At present, the dynamic weighing technology of finished rice mills in China can only control the error to 10‰, and the error in weight leads to the poor consumer experience. In order to protect consumers' rights to purchase rice, the weighing system of the new IoT rice mill will be improved from both hardware and software. In terms of hardware, the structure of the weighing system is modified to improve the sensing sensitivity. In terms of software, the error expectation value is statistically analyzed by recording big data multiple times. The hardware and software are two-pronged, and the weight of the finished product is less than 6‰, achieving an international leading level.
Improved noise reduction: noise reduced to less than 60 decibels
Due to the operation of the rice mill machine, the noise mainly comes from the whitening room and the fan (rice recovery unit). In order to reduce the noise of the rice mill, first start from the noise source, dynamic balance treatment of the rice mill machine spindle before installation, reduce the vibration intensity by increasing the proportion of symmetrical structure to achieve the noise reduction effect. In addition, in the limited space of the machine body, by increasing the coverage area of the soundproof material, the machine working noise is absorbed. At present, the noise of domestic rice mill machines is mostly above 85 decibels. The improvement goal of the new IoT rice mill machine is to reduce the noise to 60 decibels (normal conversation volume) and below.
In addition, the new IoT rice mill machine will also research and improve energy-saving and efficiency, rice preservation technology, and integrate into the IoT rice milling terminal with smarter, lower power consumption, better applicability, and better rice quality. Not only allows consumers to easily buy healthy and high-quality milled germ rice, save energy and reduce emissions, reduce food losses, and form a larger social comprehensive benefit.
