Three-Fan Large Soybean Thresher

የ 5TD-220 three-fan large soybean thresher is built for processing plants and big farms: it processes 1,800-3,000 kg of soybeans per hour — about 14.4 to 24 tons in an 8-hour working day — in one pass that threshes, cleans and bags the grain. Its performance numbers are above 99% threshing rate, breakage at or below 2.5%, and final grain impurity at or below 1.5%. You can power it with an 18 kW or larger electric motor, a 28 HP diesel engine, or a tractor PTO shaft, whichever energy source your site already has.

This page covers the full specification, how the three-fan cleaning line removes trash in a single run, the six assemblies the machine is built from, the three power packages, and an honest side-by-side with the smaller 5TD-900 soybean thresher so you can pick the right capacity class.

What the Three-Fan Cleaning System Does

Threshing a soybean is the easy part. The hard part is getting a bag of grain that is clean enough to sell or process, without cracking the beans on the way. That is where the three-fan system on the 5TD-220 does its work, in four stages:

• Primary cleaning — fish-scale long-hole sieve. Grains falling from the threshing drum land here first; undersize trash and pod fragments drop through to the ground instead of entering the grain path.
• Secondary cleaning — long-hole sieve. The vibrating screen moves the grain across this second sieve, where remaining small impurities pass through and the beans continue toward the fan inlet.
• Three suction fans. As grain reaches the suction inlet, the three fans pull light debris — chaff, dust, and shriveled pods — out of the airstream and blow them clear of the machine, while the heavier clean beans stay on the screen.
• Final sizing and bagging. Cleaned grain passes a small round-hole sieve and goes straight into the bag; larger residues such as stalk segments exit through the residue outlet at the end of the screen.

The result is a combined threshing-and-cleaning run with impurity held at or below 1.5%, so the grain coming out of the discharge is ready for storage or the next processing step without a separate cleaning machine.

How the 5TD-220 Large Soybean Thresher Works

The working sequence runs from feed hopper to bag in five continuous steps:

• Automatic feeding. The auto feed hopper is driven by a triangle belt connected to a chain that moves the horizontal feeding layer, carrying the bean crop steadily into the threshing roller — no hand-feeding at the drum mouth.
• Threshing by rubbing and impact. Inside the roller section, the crop turns in a nail-toothed drum while pressing against the fixed separator screen (friction-strip screen) mounted on the frame. The combined rubbing and striking action cracks the pods open and releases the beans.
• Distribution to the vibrating screen. Released beans drop directly onto the vibrating screen, which moves them forward in a controlled layer toward the cleaning line. The drum runs at 480-570 r/min — fast enough for throughput, slow enough to protect whole beans.
• Three-stage cleaning. The fish-scale sieve, long-hole sieve, and three suction fans described above remove trash in a single pass.
• Straw discharge. The straw guide plate guides threshed stalks out the straw outlet at the end of the drum, keeping the work area clear instead of recirculating into the machine.

Six Core Assemblies of Big Soybean Threshing Machine

The large soybean thresher machine is built from six parts, each responsible for one stage of the work:

• Frame. Welded from angle steel and channel steel, it carries every other assembly and completes the feed, threshing, cleaning, bagging, straw discharge and travel sequence as one rigid unit.
• Automatic feed hopper. Triangle-belt-and-chain driven, it meters the crop into the roller so feeding speed matches threshing speed.
• Threshing section. Drum, separator screen, guard plates, hood and residue outlet — the components that crack pods and release grain without over-processing the beans.
• Cleaning section. Primary fish-scale sieve, secondary long-hole sieve and the three suction fans that give this model its name.
• Transmission. A triangle-belt drive spins the threshing roller and runs the fans, vibrating screen and grain hopper in synchronization from a single power source.
• Travel section. A no-adjustment lifting travel-wheel set lets you move the 1,050 kg machine between sheds, yards and field edges without re-rigging it.

Three Power Options, One Transmission

The 5TD-220 large soybean thresher ships ready for whichever power you have on site. All three options drive the same triangle-belt transmission, so the drum, three fans, vibrating screen and feed hopper always run in step:

• ≥ 18 kW electric motor. The best choice for a fixed processing site with reliable power — lowest running cost per ton and no fuel handling on the yard.
• 28 HP diesel engine. The standard matched power for this model. Self-contained and independent of the grid, suited to farms and buying centers where electricity is unreliable or absent.
• Tractor PTO shaft. If your farm already runs a tractor, connect the PTO and reuse it as the power unit — one less engine to service, and the machine moves with the tractor between work sites.

The same three-power approach runs across the Taizy thresher line, including the multi-purpose sorghum threshing machine እና multifunctional thresher, so parts familiarity and operating habits carry over between machines.

5TD-220 vs 5TD-900: Which Capacity Class Do You Need?

Taizy offers two soybean threshers that look similar on paper but serve different scales of work: the 5TD-220 large soybean thresher on this page and the compact 5TD-900. The honest comparison:

	5TD-220 (this machine)	5TD-900 soybean thresher
አቅም	1,800 – 3,000 kg/h	500 – 700 kg/h
የመውቂያ መጠን	> 99%	≥ 99%
የመሰባበር መጠን	≤ 2.5%	≤ 0.5%
ማጽዳት	Three-fan system, impurity ≤ 1.5%	Single suction fan, total loss ≤ 1.0%
ክብደት	1,050 kg	400 kg
የእግር አሻራ	4,280 × 1,450 × 2,200 mm	340 × 170 × 140 cm
ኃይል	18 kW+ motor / 28 HP diesel / PTO	7.5 kW+ motor / 12-15 HP diesel / PTO
Best suited to	Processing plants, large farms, custom threshing crews	Family farms, small workshops, pilot operations

The trade-off is deliberate: the 5TD-220 moves three to four times the tonnage per hour and cleans it with three fans, while the smaller 5TD-900 keeps breakage at or below 0.5% on a 400 kg frame one person can reposition. If your daily volume is under about 5 tons, the small unit is the better fit; above that, the 5TD-220 pays for itself in hours saved. For still smaller or mixed-crop needs, the small scale grain thresher covers grains in the same workflow.

Built for Scale: What 1,800-3,000 kg/h Means in a Working Day

Rated capacity is only useful when translated into a shift. At the rated range, one 5TD-220 large soybean thresher handles:

• 14.4 tons per day at the conservative end (1,800 kg/h × 8 hours)
• 24 tons per day at full rate (3,000 kg/h × 8 hours)
• One operator feeding, one bagging — the auto feed hopper and bagging outlet keep the labor count low for the throughput

That puts the machine in front of buyers running bean processing plants, large soybean farms, cooperative buying points, and contract threshing crews who move from farm to farm during harvest. The travel-wheel set matters here: the machine is repositioned around the yard or between fields without a crane.

Grain that still needs peeling heads next to the የባቄላ ልጣጭ ማሽን; farms also running cereals can pair it with the multifunctional wheat thresher, which handles soybeans among its crops. For a wider look at what one multi-crop unit covers, see what is the use of a multi crop thresher.
