Parboiled rice milling uses steamed rice as raw material, after cleaning, soaking, cooking, drying and cooling, then press the conventional rice processing method to produce the rice product. The finished parboiled rice has fully absorbed the nutrition of rice and has good flavor, also during the course of boiling it killed the pest and make rice easy to store.
1. Descriptions of Our 200-240 t/day Complete Rice Parboiling and Milling Line
Paddy parboiling as name states is a hydrothermal process in which the starch granules with in the rice grain are gelatinized by the application of steam and hot water. Parboiled rice milling uses steamed rice as raw material, after cleaning, soaking, cooking, drying and cooling after heat treatment, then press the conventional rice processing method to produce the rice product. The finished parboiled rice has fully absorbed the nutrition of rice and has good flavor, also during the course of boiling it killed the pest and make rice easy to store.
We do able to supply auto modern complete parboiled rice milling plant with series production capability for your demand. The complete parboiled rice milling plant is usually made of two main parts: rice parboiling section and rice milling section.
2. Process Details for Parboiled Rice Milling are as following:
1) Paddy Cleaning: In this stage we remove the impurities from the paddy.
The rice should be cleaned first to remove the straw, stones, jute rope, other large debris and impurities such as dust mixed into the rice. If the paddy has dust when it is soaking it will pollute the water and influence the nutrition of rice. Also, after the cleaning process, failure of downstream processing equipment or damage to components can be effectively avoided, which is a key process of a complete set of rice parboiling equipment.
2) Paddy Soaking: The aim of soaking is making paddy absorb enough water, create conditions for starch pasting. During the course of starch pasting paddy must absorb above 30% water, or it will not be able to fully steam the paddy in next step and thus to influence the quality of rice.
a. Through vacuuming, constant temperature, and pressure soaking, the water is fully absorbed by the rice in a short time, so that the water content of the rice reaches more than 30%, which is a necessary condition for the rice starch to be fully gelatinized during the cooking process. In the parboiled rice production line, this processing section is the basic and important section.
b. Depending on the variety and quality of rice, the soaking temperature is usually 55-70 degrees, and the soaking time is 3.5-4.5 hours.
3)Steaming and Boiling: After soaking the inside of endosperm has got enough water, now it's time to steam the paddy to realize starch pasting. Steaming can change the physical structure of rice and keep the nutrition, to increase the production ratio and make rice easy to store.
In this process, high-pressure and high-temperature steam is used. The temperature, time, and uniformity of steaming must be strictly controlled so that the starch in the rice can be fully gelatinized without excessive.
When starch gelatinization is sufficient, the color of the processed finished parboiled rice is transparent honey-colored.
By adjusting the cooking parameters, parboiled rice with light color, sub-dark color, and dark color can be processed according to customer requirements.
4) Parboiled Paddy Drying: The aim of drying is to make moisture reduced from around 35% to around 14%, to reduce moisture can make the rice easy to store and transport, and greatly increase the production ratio, as the maximum whole rice rate can be obtained when rice is milled.
We use the heat of the boiler during this process, it is converted into the air through the heat exchanger, and the rice is indirectly dried, and the dried rice has no pollution and no peculiar smell.
The drying process is divided into two stages. The first stage is fast drying, which reduces the moisture content of the paddy from more than 30% to about 20%, and then slow-drying to make the paddy fully slow down and reduce the waist burst rate. Improve the whole meter rate.
5) Parboiled Paddy Cooling: The dried paddy is sent to vertical storage for temporary storage so that it is fully slowed down and cooled before being processed. The vertical cylinder warehouse is equipped with a ventilation fan, which can take out the remaining heat. And make the rice moisture evenly.
6) Rice Husking and Separation: Using the rice hulling machine to remove the husk of dried paddy. After soaking and steaming it will be very easy to husk the paddy and save energy.
The paddy separator is mainly used for separating brown rice from paddy by their differences in specific gravity and friction coefficient in three parts: paddy, brown rice, and a mix of both.
7) Rice Milling: The pearling of parboiled rice cost much more time than normal paddy. The reason is that after soaking the rice is easy to become smectic. In order to avoid this problem, we use blowing rice miller and increase the rotating speed of rice miller, the rice bran transmission adopt pneumatic type to reduce the friction.
The rice milling machine is developed for rice milling, which is an advanced technology of the world rice mill whitener at present to make rice temperature down, bran content less, and broken increment lower.
8) Rice Polishing: The rice polishing process is to polish the rice surface by spraying water, which facilities the formation of a smooth gelatinous layer that prolongs the preservation time. Extended polishing chamber to produce high-quality rice. Good rice come through the polishing machine, it will make the milling rice become more beautiful color and glossy, thus to increase the quality of rice.
9) Rice Grading: Rice grading machine is used to sieve the milled rice efficiently and accurately into several classes: head rice, large broken, medium broken, small broken, etc.
10) Rice Color Sorting: The rice we get from above step still has some bad rice, broken rice or some other grains or stone. So here we use color sorting machine to select the bad rice and other grains.
Color sorting machine is an important machine to ensure we can get high quality rice. Using the rice color sorting machine to sort the bad, milky, chalky, paddy, and foreign materials out. The CCD signal while blanking is been tested. If it is found that there are unqualified rice or impurities in the materials, the ejector will blow the defective goods in the hopper.
9) Finished Rice Packing: The finish rice now is ready dear all! Let's use our automatic weighing and packing machine to make them into 5kg 10kg or 50kg bags.
This rationed automatic weighing packing machine consists of a material box, a packing scale, a sewing machine, and a conveyor belt. It can cooperate work with all the model's rice mill production lines. It is electric type, you can set it like a small computer, then it will start working. For the packing bag capacity can choose 1-50kg per bag according to your request. From this machine you will get bag type rice and you can supply your rice to all your customer!
It can be seen from the processing process of parboiled rice that the production process of a full set of the paddy parboiling plant is based on the processing technology of white rice, adding hydrothermal treatment processes such as soaking, steaming and boiling, drying and cooling, and slow stewing. The whole process of parboiled rice production generally includes two parts: rice parboiling part and rice milling part, which like this:
1. Rice Parboiling Section:
Raw Paddy → Pre-Cleaning → Soaking → Steaming and Boiling → Drying → Cooling → To Rice Milling
2. Rice Milling Section:
Parboiled Paddy → Husking and Separating → Rice Milling →Rice Polishing and Grading → Rice Color Sorting → Rice Packing
The selection principle of paddy parboiling plant output mainly depends on the output and power of the subsequent rice milling machine. There must be a sufficient amount of parboiled rice before the rice hulling process can run. The output of the pre-parboiled equipment must be greater than the output of the subsequent rice mill. If that's not enough, two units can be connected in parallel. When the output is consistent, use a rice pre-parboiler with less power.
