15T/D integrated rice milling unit can mill rice with high working efficiency, and it has four models including standard type, medium type, high-end type, deluxe type. They look similar but still have something different. All rice milling rates can reach 71%, and the processed rice is equipped with high quality. Thanks to high milling precision, compact structure, and excellent output, this series of integrated rice milling units are pretty popular in the rice processing industries.
The operation video
The structure of integrated rice milling unit
The integrated rice milling unit is mainly compose of 120 parts, and each part is dismountable,that is,
- Feeding hopper
- Single hoist
- Rice destoner
- Rice husking machine
- Double hoist
- Gravity screen
- Electric cabinet
- Rice milling machine
- Rice husk crushing machine
- Hoist
The working steps are like this, 1-2-3-5-4-5-6-8-10-11-12-9, you may be confused as that why the rice goes back to double hoist? Because the rice that still has husk will be conveyed by double hoist into rice husking machine, such operation can fully improve the husking rate.
What is the workflow of the integrated rice milling unit?
The harvested rice is going to threshing. The threshed rice can be milled.
The first step in rice milling is to remove the stones, which is to remove the small stone, soil blocks, iron flakes, and other impurities in the rice.
The second step is to remove the rice husk, which is to remove the outer husk of the rice.
The third step is sieving, which is to sift out brown rice and paddy. The paddy is then dehulled and turned into brown rice.
The fourth step is rice milling, which is to milling brown rice as white rice.
The fifth step is color selection, which is to select moldy rice, black rice, impurity rice, etc., according to the color difference.
The last step is screening. The sieved rice is cleaner and has a more uniform particle size.

process of rice milling
Type one: standard type integrated rice milling unit
The standard type integrated rice milling unit is a most common one, and its capacity is 600-700kg/h. It include silo, stone removing machine, rice dehuller machine, gravity grading sieve, rice milling machine, linear sieving machine.
Technical parameter
| Dimension | 3000*2600*2900mm |
| Capacity | 600~700kg/h |
| Rice milling rate | 71% |
| Total power | 19.25Kw(without crushing machine) |
| 26.25Kw(including crushing machine) |
Type two: medium type combined rice milling machine
Medium type combined rice miller add a rice husk crushing machine and Shakron on the basis of the standard. The special design of the cyclone on the end of the crushing machine can effectively avoid dust flying around the air, which is environment friendly.
Technical parameter
| Dimension | 3000*2600*2900mm |
| Capacity | 600~700kg/h |
| Rice milling rate | 71% |
| Total power | 27.35Kw(including crushing machine) |
Type three: high-end type integrated rice miller
The structure of the high-end type integrated rice miller is the same as the medium type combined rice milling machine. The most proficient feature of the High-end type integrated rice miller is that it can convey rice pneumatically, so it can remove the rice husk inside the final rice and improving the quality of rice.
Technical parameter
| Dimension | 3000*2600*2900mm |
| Capacity | 600~700kg/h |
| Rice milling rate | 71% |
| Total power | 20.35Kw(without crushing machine) |
| Total power | 28.45Kw(including crushing machine) |
Type four: deluxe type combined rice miller
Deluxe type combined rice miller is the most advanced type, and it not only has a rice husking crushing machine, special pneumatic hoist to convey rice but add a rotating grading sieve that can screen in a multistage level, increasing the cleaning rate. Also, you can equip with color sorter. So your rice is of high quality and can get a very high price in the market.
Technical parameter
| Dimension | 3300*2600*2900mm |
| Capacity | 600~700kg/h |
| Rice milling rate | 71% |
| Total power | 20.35Kw(without crushing machine) |
| Total power | 28.45Kw(including crushing machine) |
What is the role of a crushing device?
The crushing device can be added according to your own needs. Our entire integrated rice milling unit does not include this crushing device. What can the shredder do?
The crushing device can crush the rice husk, and the crushed rice husk can be used as livestock and animal feed by adding cornflour. In addition, the crushed rice husk can be used as biomass fuel.
How to install and maintain the integrated rice miller?
1. The driving shaft of integrated rice miller must be level during installation.
2. The roller must not be loose, and it is strictly prohibited to use it if there is a crack.
3. The assembly of the rice sieve should keep horizontally, and the connection should have a flat joint, and the gap of the connection is less than 5mm at the joint.
4. You need to replace the screen of integrated rice miller in time if it is wear is severely, otherwise the rice broken rate will increase.
4. All parts in the whitewashing room should be kept smooth, and there should be no obvious unevenness. 5. Always keep the bearing full of butter, pay attention to the bearing temperature, and clean the bearing regularly.
6. If the broken rice content is gradually increased, you should check it and find the reason at once.

The common problems and solution of integrated rice milling unit
| The name of parts | Malfunction | Reason | Solution |
| Rice destoner | There are many rice in the stone | 1. The rice removing track may deviate.2.rice flow is too large or small | Install the each part again. |
| The rice can not be discharged completely. | 1.Uneven rice flowing2.The destoner slate is not horizontal3.The unevenness of destoner slate 4.Severe vibration of integrated rice milling unit | ||
| There are many stone in the rice. | |||
| Rice husking part | Low shelling rate | Rice entering flow is large2.The water content of rice is high 3. The pressure of roller is low. | 1. control the rice flow speed.2. proper adjust and master the shelling rules3. replace the spring |
| Rice broken rate is increasing | The pressure of roller is low | Expand properly the gap between rollers | |
| The integrated rice milling unit stops suddenly | The rollers are blocked by brown rice | Close the feeding plate,and loose the roller |
Advantage of integrated rice milling unit
- There are four different types of integrated rice milling units, and you can choose according to your need.
- All rice milling rate is 71%, and such a number is higher than other rice milling machines.
- We can customize the machine for you on the basis of your need. For example, you can add different parts to the whole machine such as rice husk crushing machine, square screen, color sorter, etc.
- The whole operation just is simple and just needs one person to operate it.
- A high cleaning rate is the biggest advantage of it, and you do not process the final rice again, saving time and energy.
