To meet different customer requirements Its configuration is highly customizable But the essence remains the same Today, let's take a look at Small combined rice milling equipment The rice milling process starts with our elevator The elevator is mainly used to transport our materials The rice enters the cleaning part of our equipment through the elevator Which is the cleaning and destoning combination machine This cleaning equipment features a rotary double-layer screen The top layer removes large debris like straw and stalks The bottom layer removes small debris and dust The cleaned rice then enters the destoning section Specifically, the gravity destoner The destoner relies mainly on airflow adjustment According to different densities To separate heavier materials in the rice Such as stones and rocks Our cleaning process is thus completed Next is the huller for dehusking The huller mainly relies on two rubber rollers With pressure applied by the pressing head To squeeze the rice between the two rollers Achieving the purpose of dehusking Then through the husk separator To separate the husks Obtaining what we commonly call brown rice The hulling efficiency is not 100% But it can reach at least 85% The brown rice then enters the gravity paddy separator through an elevator The function of the gravity separator Is to separate brown rice from the unhusked rice Unhusked rice goes back to the huller Brown rice goes directly to the rice whitener The main function of the rice whitener Is to remove the bran layer from the surface of brown rice Turning brown rice into white rice The rice whitener can be divided into sand roller whitener and iron roller whitener The sand roller uses the sharp edges of carborundum To remove the surface layer of the rice grain While the iron roller whitens by friction Between the rice grains and the whitening components And among the rice grains themselves Thus, the iron roller whitener applies greater pressure According to the process of multi-machine light whitening For different types of rice, Different combinations are used Normally, Japonica rice can use a combination of sand and iron rollers, such as one sand and one iron, or two sand and one iron Indica rice, being slender Can break under too much pressure So it’s not suitable For iron roller combinations It’s better to use two or three sand rollers Some fans asked about having both Indica and Japonica rice How to configure then? In such cases We can choose two sand and one iron, or three sand and one iron Or three sand and two iron, etc. After the whitening process The rice has turned into white rice At this stage We only need to add a white rice grader And the whole process is completed However, for small rice mills or cooperatives that need market sales The black and yellow grains in the rice need further removal Therefore, a rice color sorter is needed The color sorter uses the optical properties of the rice And photoelectric technology To separate black and yellow
