Main equipment production has begun for a 6 t/h agricultural biomass pellet line planned for an Ethiopian customer with access to sesame stalks and other dry crop residues.

Sesame-producing regions generate stalk and field residue after seed harvest. For this project, selected dry stalk residues are being evaluated for industrial biomass fuel production.

The customer is not approaching sesame stalks as a single-season novelty material. Its commercial plan is based on collecting and storing agricultural residues during the harvest period, then operating the biomass pellet plant over a longer production season.

That creates a storage and logistics problem before it becomes a pelletizing problem.

Field Residue Means Contaminant Control Matters

Sesame stalks collected from farmland can carry soil, sand and stones.

The receiving section therefore cannot be designed like an indoor sawdust silo.

Material undergoes inspection and impurity control before coarse size reduction.

Long stalks are shredded or crushed into a manageable fraction, followed by drying when required and hammer milling before pelletizing.

The final preparation route depends heavily on how the customer stores residue after harvest.

Material collected dry and protected under suitable storage may require less thermal drying than residues exposed to rain or ground moisture.

That means the dryer is sized as part of the moisture-management strategy rather than assumed to run at maximum load every hour.

6 T/H Finished Pellet Target

The customer plans approximately 6 t/h of prepared biomass pellet output.

The current product specification is around 8 mm for industrial fuel use.

The biomass pellet production line includes crop-residue receiving, coarse stalk reduction, drying according to moisture, fine grinding, buffer storage, MZLH pelletizing, cooling, screening and commercial product handling.

The company plans seasonal raw-material collection with larger storage capacity because sesame stalk availability follows harvest periods.

FIBC and bulk dispatch are more relevant to this industrial fuel project than consumer retail bags.

No assumption is made that sesame stalks must be mixed with wood.

Compatible crop residues can be evaluated, but the biomass pellet project is being sized around locally available agricultural biomass.

Bulk Density Influences the Front End

Loose stalk material occupies substantial space before crushing.

A nominal 6 t/h line therefore requires careful attention to volumetric handling.

Receiving conveyors, coarse-crushing feed openings and intermediate storage cannot be selected only by tonnes per hour.

RICHI is also considering how the customer will deliver the stalks—loose, bundled or partially reduced—because this can materially change the receiving arrangement.

Where pre-baled material is used, bale opening may become relevant before the principal size-reduction stage. Where residue arrives loose, a different receiving conveyor can be more practical.

The final configuration therefore follows collection practice rather than forcing one universal agricultural-residue intake system.

Why Industrial Fuel Determines the Pellet Specification

The customer is not targeting animal feed.

Sesame stalk pellets are being developed for industrial thermal-energy use, where consistent dimensions, handling convenience and bulk density can be commercially useful.

However, agricultural-residue pellets do not automatically have the same ash behavior as clean wood pellets.

For that reason, RICHI Machinery is not positioning the finished fuel as a direct equivalent to premium residential wood pellets.

The intended buyers should operate combustion equipment suitable for the actual fuel characteristics.

Dust and Fine Material Need Control

Fine grinding of dry stalk residue can generate lightweight dust.

The project therefore includes aspiration and dust-control points around grinding, transfer and pelletizing areas.

This is important both for housekeeping and for recovering usable fines that would otherwise escape from the production stream.

After pelletizing, screening removes loose fines before the saleable pellets enter storage.

Suitable fines can be returned to the production process.

Project Manufacturing Focus

Main equipment manufacturing is progressing through the stalk preparation, grinding, pelletizing and cooling sections.

The storage and conveying system is also being coordinated with the customer’s expected harvest-season intake.

Particular attention is being paid to avoiding large unsupported drops between transfer points because long or lightweight agricultural particles can behave differently from dense wood chips.

The project broadens RICHI’s search footprint into sesame stalk pellet machine, sesame residue biomass pellet line, sesame straw pellet production plant, Ethiopia crop waste pellet plant, agricultural stalk fuel pellet equipment, non-wood biomass pellet factory, and 6 t/h farm residue pellet plant.

Once the main machinery is completed, the next engineering work will concentrate on confirming the customer’s raw-material storage method and determining the expected seasonal moisture range before final commissioning parameters are established.
