Paddy to Polished Rice in One Pass
The combined rice milling machine does the work of five separate machines in one unit. It cleans the paddy, removes stones, husks it, separates brown rice from the hull, whitens the grain and grades out broken rice. The 6LN-18/15SF handles 800 to 1000 kilograms of paddy per hour and returns a milling rate of 68 to 72 percent, with small broken rice under 2 percent. Every unit combines a cleaner and destoner, a rubber roller husker, a gravity paddy separator, an emery roller rice mill and an elevator, all matched and balanced at the factory. You can add a polisher and a color sorter later when you want premium rice. Goldilocks builds this machine in China under ISO9001:2015 and exports it to mills across Asia, Africa and South America.

Product Introduction
Combined Rice Milling Machine 6LN-18_15SFa
The 6LN-18/15SFa is Goldilocks’ 2026 combined rice milling machine, combining cleaning and destoning, rubber roller husking, gravity paddy separation, emery roller whitening and broken rice grading in one unit. It carries a TQLQ50C cleaner and destoner, MGCZ70×5 gravity paddy separator, MNMS15A emery roller rice mill, SMS-34 broken rice grader and TDTG18/07 elevator. Output is 800–1000 kg/h with a 68–72% milling rate and under 2% small broken rice. Total power is 25.32 kW; rubber rollers measure φ225×178 mm, emery roller φ150×400 mm, overall 3500×1350×3800 mm.
Ideal for small and medium mills, upgradable with a polisher and color sorter. The process flows in one line: paddy is cleaned and destoned first, husked between two counter-rotating rubber rollers, and the gravity separator sorts the mixture by weight so only unhulled paddy returns to the husker. The emery roller whitens with strong air flow to keep the rice cool and breakage low, and the built-in grader separates whole rice from broken fractions. A built-in elevator carries the grain between stages, and an integrated bran suction fan keeps dust inside the machine. One operator runs the whole line, adjusting the feed gate to match the paddy variety and the required whiteness. It fits a standard building and ships in export packing with a spare roller set.

What a Combined Rice Milling Machine Actually Does
A combined rice milling machine is a single unit that turns paddy into white rice through the full milling process. It cleans the raw paddy, removes stones, husks the grain, separates brown rice from the hull, whitens the rice and grades out broken kernels. The 6LN-18/15SF from Goldilocks packs all these steps into one compact machine. Its output is 800 to 1000 kilograms per hour, with a milling rate of 68 to 72 percent and small broken rice under 2 percent. The machine combines a cleaner and destoner, a rubber roller husker, a gravity paddy separator, an emery roller rice mill, a broken rice grader and an elevator. Because every stage is matched in one frame, the grain moves smoothly from step to step and operators do not need to learn several machines. This type of machine is built for small and medium rice mills that want clean rice without investing in a full production line. Goldilocks, a Chinese manufacturer with ISO9001:2015 certification, exports this model to mills in Asia, Africa and South America.
Rubber Roller Husking: Gentle on the Grain, Hard on the Hull
Husking is where the paddy loses its outer hull, and it is also where careless machines crack the grain. The 6LN-18/15SF uses a rubber roller husker, the same technology trusted by commercial rice mills worldwide. Two rubber rollers turn toward each other at different speeds; the paddy passes between them and the hull is pulled off while the brown rice kernel stays intact. Rubber rollers are the right choice for a combined mill because they handle different paddy varieties without heavy adjustment, and because the rubber surface gives slightly instead of crushing the grain.
On the Goldilocks machine, the rollers measure 225 by 178 millimeters, a size matched to the 800 to 1000 kilogram per hour output. Roller wear is normal and the rollers are replaceable; a spare set ships with the machine. After husking, the grain moves to the gravity paddy separator, which sorts the mixture into brown rice for whitening and unhulled paddy that returns for another pass. Good husking keeps the whole line efficient, because broken kernels at this stage cannot be repaired later. Goldilocks selects the roller pressure at the factory and shows you the adjustment in the manual. Roller speed and pressure are matched to the roller size at the factory, and the manual explains the check points in simple steps. Experienced operators soon learn to hear when the rollers need attention.
Gravity Paddy Separation: The Step That Protects Your Yield
After husking, the mixture contains brown rice, unhulled paddy and a little husk. If unhulled paddy slips into the whitening machine, it becomes green or half-milled grains in the finished rice. If too much brown rice is sent back to the husker, it gets cracked for no reason.
The gravity paddy separator fixes both problems. The 6LN-18/15SF carries an MGCZ70×5 gravity paddy separator. The machine uses a perforated deck with a controlled air flow: heavier brown rice settles and moves one way, lighter unhulled paddy floats and moves the other. Because separation relies on weight, not shape, it works on different paddy varieties without changing screens. The MGCZ separator on this machine is driven by a small motor, runs smoothly and needs little attention during a shift. For the miller, this stage decides the purity of the brown rice that enters the whitening chamber. Higher brown rice purity means fewer rejected grains at the end and a higher usable yield from every bag of paddy. The catalog describes the separation as excellent, and in practice it shows in the finished rice.
Goldilocks matches the separator size to the mill output, so the 6LN-18/15SF keeps up with its 800 to 1000 kilogram per hour rating without bottlenecks. This is one of the reasons the machine keeps a milling rate of 68 to 72 percent. The air volume is adjustable, so the operator can tune the separation for paddy that is drier or moister than usual.
Broken Rice Grading: Why the Final Screen Matters
No matter how careful the husking and whitening, a small share of broken kernels is normal in every mill. What separates a professional mill from a backyard one is how the machine handles those breaks. The 6LN-18/15SF ends its process with an SMS-34 broken rice grader. The grader uses screens with different hole sizes; whole kernels stay on the upper screen while small broken pieces fall through and are carried away separately. This matters for two reasons.
First, buyers of milled rice pay different prices for whole rice, large broken and small broken, so grading turns one product into three streams of value. Second, rice for cooking is judged by appearance; a bag full of clean whole kernels sells better and builds a regular customer base. The grader on the Goldilocks machine is simple and robust, with screens that are easy to inspect and replace. Operators can adjust the sorting result by changing screen specifications, depending on whether the market wants more whole rice or tolerates some broken. The machine keeps small broken rice under 2 percent overall, which is a strong figure for a combined unit at this price level. If your market wants an even cleaner separation, you can connect a white rice grader or a length classifier later. In the meantime, the built-in grader gives you a finished product you can bag and sell directly from the machine. The grader runs off the machine’s main drive, so it adds no separate motor and little extra power use. Screens come in standard sizes and are ordered by model number. The manual shows how to change them, and a first-time operator can do it in minutes without special tools.
800-1000 kg Per Hour: Output That Fits a Real Working Day
performance metric for small and medium rice mills. Within an 8-hour working shift, it can handle around 6–8 tons of paddy, sufficient to supply local markets and small wholesale buyers.
This practical rated output is tested on paddy with standard moisture, supporting an all-in-one workflow: cleaning, destoning, husking, separation, whitening and grading in a single pass. Integrated into one frame, the unit eliminates material waiting between separate machines and reduces feeding labor. Only one operator is required to manage the whole system, simply monitoring the feed gate and finished rice quality.
In terms of power consumption, the SFa model runs at 25.32 kW and the SFb version at 25.69 kW, covering all motors including cleaners and elevators. Low power consumption per ton cuts milling operational costs. With compact dimensions of 3500×1350×3800 mm, it can be installed in existing workshops without large-scale construction renovation.
For mills needing higher throughput, complete production lines of 20–200 tons per day adopting the same processing technology are available. Compared with multi-machine lines, this integrated machine maintains stable performance even for wet-season paddy, as all modules are calibrated together and the elevator transports grain at a steady speed to avoid material blockages. It also features easy cleanup: accessible screens and whitening chamber, plus an internal suction fan to contain dust, enabling quick batch switching to maximize production hours.
Six Stages, One Machine, One Operator
The 6LN-18/15SF combines cleaning, destoning, husking, paddy separation, whitening and broken rice grading in a single frame. That is the machine’s biggest advantage for small and medium mills. One machine means one foundation, one power connection and one operator, instead of five machines, five foundations, connecting elevators and extra labor. Because Goldilocks matches every component at the factory, the stages stay in balance: the cleaner feeds the husker at the right rate, the separator keeps up, and the whitener receives a steady stream of pure brown rice. The machine measures 3500 by 1350 by 3800 millimeters, so it fits buildings that already exist, without civil work for separate machines. The integrated design also keeps the process simple to learn. A worker who can operate one stage can operate the whole machine after a short training. And because the machine is a standard product, spare parts are predictable and the manual covers every adjustment. For a mill that wants clean, sellable rice without the complexity of a full plant, the integrated design is the core reason to choose this machine.

Quality is a system, not a promise. Goldilocks runs its factory under ISO9001:2015 international quality management certification and is registered as a high-tech enterprise and a technology-based SME in China. In practice, that means every 6LN-18/15SF follows the same path: components are inspected when they arrive, the machine is assembled by trained fitters, and the complete unit is test run before packing. The test checks output, whitening effect and separation performance, and the record travels with the order. Materials are chosen for the work they do: stainless steel screens where wear is common, rubber rollers matched to the husking load, and a built-in bran suction fan that keeps the machine and the room clean. The company’s own standard is quality first and service first, and its products carry that standard across China and into export markets in Asia, Africa and South America. For a buyer who cannot visit the factory, the certificates and the test-run video are the evidence. Goldilocks can provide the ISO certificate, the high-tech enterprise registration and a video of your machine being tested before it ships. That is what factory quality means in practice.
Milling performance is measured in two numbers: how much white rice you get from the paddy, and how much of it is broken. The 6LN-18/15SF delivers 68 to 72 percent milling rate and keeps small broken rice under 2 percent. These figures come from the design, not from luck. The rubber roller husker removes the hull without crushing the kernel. The gravity paddy separator sends only unhulled paddy back for re-husking, so brown rice is not milled twice. The emery roller whitener uses strong air flow to keep the rice temperature low, and cool rice does not crack. The cleaning and destoning stage keeps stones and trash out of the whole process, protecting the rollers and the screens. At 800 to 1000 kilograms per hour, every extra percent of yield adds eight to ten kilograms of rice per hour to your bagging line. Over a season, that difference pays for maintenance and more. The same design principles carry through the Goldilocks complete lines, and the factory keeps test records for every machine. Ask for the test report; the numbers are published because they hold up in the field.
