Good day, House. I want to share a machine we just landed for serious grain operations — the kind that 50-1,000 hectare farms, regional depots, and buying stations need during harvest season.

The Taizy SL-368 is a large-capacity, tow-behind maize thresher. It runs on a 30kW three-phase motor (380V/50Hz) and processes 20-30 tons of maize per hour. Three dust-removal fans in series and a double-layer vibrating screen clean the grain in one pass. The 3,800mm discharge spout loads straight into standard grain trucks or storage silos — no shoveling, no second handling.

Why this one fits Nigeria and West Africa:

We all know the power situation. The SL-368 needs stable three-phase — that is the trade-off for an industrial electric thresher. For buyers with a transformer at the depot, a 50-60kVA diesel generator can run the unit if grid power drops. Electric threshing costs 30-50% less per ton than a diesel equivalent, and there is no engine service (no oil changes, no fuel filters, no radiator).

For tropical and subtropical regions where maize comes off the field at 20-30% moisture, the nail-tooth cylinder is the practical fit. A rasp-bar unit needs maize dried to 14-18% to thresh cleanly. If you are threshing straight from the field during the rainy season, nail-tooth is the right pick.

Five things that make a real difference on a working site:

1. 20-30 tons/hour — replaces a hand-shelling crew of 30-50 people. One operator supervises the SL-368.
2. 3 dust-removal fans (configurable to 2) + double-layer vibrating screen — grain comes out at commercial grade 2 or better.
3. 3,800mm discharge height — clears the side of a standard grain truck, trailer, or small silo. Direct load.
4. Tow-behind frame hooks to any standard tractor or pickup with a trailer hitch. Position at the edge of the maize pile, level the support legs, connect the power cable, start threshing.
5. 3-5 day production lead time. Most industrial threshers in this class ship in 15-25 days. For a buyer chasing the early-season premium price, that gap is the difference between catching it and missing it.

Numbers for those who want the math:

The SL-368 is built to industrial spec — 2 tons net weight, 4100×1800×2900mm footprint, 30kW three-phase drive, 3.8m discharge. It fits a 20GP container for export. CIF Lagos (Apapa) or Tin Can Island shipping fits 1-2 units depending on configuration. Lead time: 3-5 days production, 28-35 days shipping to Lagos.

A simple ROI example: a buying station running the SL-368 for 10 hours a day over a 60-day harvest produces 12,000-18,000 tons of cleaned maize. At ₦10,000-15,000/ton contract threshing fees (USD 5-8 at current rates), gross revenue lands at ₦120-270 million per season. Operating cost (electricity, labor, maintenance) is usually 25-35% of gross, leaving net operating income of ₦80-180 million. The unit pays for itself in the first season for most buyers.

What is in the crate:

- 1 SL-368 main machine (tow-behind frame, 30kW motor, 3 dust fans, double-layer vibrating screen)
