Making profit from rice has become so hard in today’s commercial conditions since its high financial value and competition. In this article, I will evaluate the critical points that can increase your profit in rice processing.
Rice milling is a very delicate process. It requires more technique, knowledge and attention than other grains. Because paddy is fragile. Any additional yield is important and affects the profitability of the business; ie the difference in efficiency…
If you care about your business and do not want to lose money, you should definitely pay attention to these recommendations.
Whiteness, transparency and broken rate are very important in rice. You need to have a good laboratory to detect them. Your laboratory will be used both during the purchase of paddy and during the operation of the factory. First of all, it is necessary to pay attention to the points that need to be considered while buying paddy.
Although paddy is divided into three main groups;
Many varieties are produced in the world, but all varieties are gathered under these three groups.
During the paddy processing, the samples taken from the machines can be tested in the laboratory and it can be observed what kind of result will be obtained. This is called yield.
For example, you can get the following fractions out of 100 kg. of paddy;
It might give a result like this. The important thing here is how can we get 62 or 65 kg of this 60 kg rice. Is it possible? Yes, it is possible.
Accordingly, the whiteness rate of rice, the broken products, raw grains, etc. are analyzed to determine what efficiency can be obtained and to get a good and quality result.
There are important devices that need to be used in the laboratory. Milling yield testing machine, whiteness meter, humidity machine, electronic image processing, etc.

This process takes about 10-15 minutes every hour - three shifts per day and 365 days a year. The observed results are then used to adjust the process until the next audit round. One problem with whiteness measurement is the effect of opaque spots in the beans, called chalky. Since the measurement is the average of the total white color, a different level of chalkiness in the sample will give different results for the ground grains, regardless of the degree of grinding. If you run a production capacity of 10 metric tons per hour, the rounded number will be about 50,000 tons per year (assuming 10 tons X 20 hours/day X 250 days per year). A simple calculation shows that every 1% loss in kernel size equals 500 tons per year. If your capacity is larger, the loss will be even greater.
Now here is the second important factor, will you get the result you tested in the laboratory in your factory? Here, of course, the importance and quality of the machine you use in the factory comes to the fore.
There are many machine manufacturers in the world, but the loss of efficiency is not under the control of most companies. There are important factors during milling. If we look at the rice processing process;
•After the pre-cleaning process, the paddy is subjected to the peeling process, that is, the separation from the shell. The pressure here is very important. Even the direction the paddy enters into the peeler rubber is important.
•The grains that are turned into cargo rice then enter the bleaching process. Here is one of the important points that should be taken care of so that the goods do not break. The aim is to go to the optimum point.
•The system you use here will add a lot to you. Optimum processing, bran amount, whiteness ratio in rice…These will even affect the cooking values of your product.
To maximize your profit in rice processing, a good laboratory, continuous and accurate testing, and a quality rice processing system should be your premise.
