Rice Straw Pellet Plant in Myanmar for Boiler Fuel

RICHI MACHINERY

Securing Usable Straw Close to Bago

Rice straw already has value on farms and in other local activities. A dependable collection business starts with the surplus farmers can release and the conditions under which it can be stored.

Straw destination	Procurement implication	Plant response
Field retention	Supports farm soil management	Purchase only available surplus
Livestock use	Competing local demand	Respect committed volumes
Mushroom growing	Quality-dependent outlet	Use separate supply agreements
Fuel collection	Requires baling and transport	Record usable dry tonnes

Drying before baling is especially important. A dense bale can retain moisture in its centre even when its surface feels dry. Supplier handling and receiving measurements work together to keep unsuitable material out of the covered stock.

Collection agreements therefore define material condition as well as tonnes. A clean dry load takes less handling and creates fewer problems in storage than a heavier load carrying soil and rainwater. Those differences eventually reach the cost of finished fuel.

Industrial sales are concentrated on users with a suitable combustion route:

Potential buyer	Delivery area	Qualification	Commercial condition
Process steam users	Bago	Furnace and ash system	Successful fuel trial
Textile operations	Bago–Yangon route	Stable feeding	Agreed specification
Food processors	Accessible regional sites	Combustion compatibility	Regular order schedule
Central boiler operators	Industrial districts	Ash and emissions assessment	Verified receiving capacity

Rice processors may already have their own husk supply. The stronger prospect is an industrial user that needs purchased fuel and has a furnace capable of handling agricultural biomass. This keeps sales effort focused on a customer’s actual operating need.

Dry Bales, Clean Fibres and a Defined Feed Route

Rice straw forms the principal material for the Bago configuration. Its low bulk density and long fibres influence nearly every part of preparation, from the bale opener to the buffer discharge.

The supply arrangement distinguishes stored dry material from exposed stock:

Check	Dry stored rice straw	Weather-exposed rice straw
Supply basis	Identified farm lots	Separate acceptance
Collection period	Linked to local harvest	Access-dependent
Moisture	Measured before use	Test bale core
Ash	Laboratory sample	Check soil contamination
Fibre condition	Dry and clean	Inspect for mould
Storage	Covered and ventilated	Hold outside accepted stock
Fuel value	Measured on declared basis	Do not infer from appearance

Incoming straw must be dry enough for covered storage. Press feed is controlled around 10–14% moisture after preparation; the selected line has no thermal dryer. Wet or heating bales remain outside accepted stock until handled through a separate, suitable route.

Responsibilities are divided across collection and factory receiving:

Source	Collection plan	Volume basis	Condition	Delivery control
Farm groups	Practical truck routes	Accepted dry tonnes	Covered bales	Supplier identification
Collection contractors	Agreed collection zones	Weighbridge receipts	Clean accepted bales	Moisture sample
Combined supply	Monthly delivery schedule	Supports planned production	Separate wet loads	Stock reconciliation

Accepted straw has three essential characteristics:

The receiving team identifies:

• Moisture suitable for storage and preparation
• Clean fibres without mould or signs of heating
• Limited soil and no plastic wrapping, twine or metal

The 600 m² bale bay is a working buffer. At 60% stack coverage, 3 m stack height and 120 kg/m³ bale density, it holds about 130 tonnes. That is roughly two production days at full output; seasonal stocks remain in separately managed supplier stores.

A Site Layout with Room for Bales and Trucks

Bales need space before they become a compact fuel. The site arrangement gives receiving vehicles, loaders and finished-product traffic separate working positions, with drainage around covered storage.

The main site functions are:

Area	Size (m²)	Function
Production building	2,100	Includes processing and working stock
Bale buffer within building	600	Included in 2,100 m²
Finished stock within building	500	Included in 2,100 m²
Office building	150	Staff and administration
Weighbridge	Entrance allocation	Receipts and dispatch
Paved circulation	About 1,200	Vehicle access
Remaining site	Within 6,000 m² total	Circulation, separation and utilities

Inside the production building, space follows the material route:

The allocation keeps preparation, pressing and clean stock distinct:

Zone	Area (m²)	Duty
Bale opening	200	Controlled primary feed
Grinding	250	Fine preparation
Pressing and cooling	350	Pellet formation and cooling
Packing and services	200	Weighing and access
Covered bale stock	600	Working buffer
Finished stock	500	Released bagged product

The six indoor areas total 2,100 m². Raw stock and finished stock each have a single allocation, while the process sections retain access for machine service. The result is a layout the operator can use throughout the shift, not just fit onto a drawing.

One Coordinated Line from Bale Opening to Packing

Equipment	Quantity	Drive basis	Function
RICHI bale opener	1	Matched to feed duty	Open accepted bales
RICHI primary cutter	1	55 kW	Shorten stems
RICHI straw hammer mill	1	132 kW	Prepare fibre
RICHI MZLH678 biomass pellet mills	2	200 kW each	4 T/H combined design duty
Extraction system	1 coordinated set	22 kW drive allowance	Collect process dust
Weighing and closing stations	2	At least 200 × 25 kg bags/hour combined	25 kg and 50 kg formats
Live-discharge buffer	1	Level-controlled	Even press feed
Conveyors, cooler and screen	1 package	At least 5 T/H on qualified material	Transfer, cool and separate fines
Loader interface	1 operating position	Local handling arrangement	Move bales and pallets

The RICHI package connects bale opening, cutting, fine preparation and pelleting with continuous cooling and weighing. Buffers and conveyors are part of the material-handling design rather than accessories chosen after the major machines.

Two MZLH678 rice straw pellet making machines with 200 kW motors divide the nominal 4 T/H duty. Each works around 2 T/H on the selected dry rice-straw preparation, leaving more drive headroom than a single press carrying the entire line. The package’s throughput is established with representative straw, not by adding motor power.

Opening, cutting and fine grinding address different stages of fibre preparation.

The Production Route, Starting with the Bale

Record the Delivery and Place the Stock

A weighbridge records incoming loads before the receiving team assigns each batch to covered storage. Supplier identity stays with the material, making changes in moisture or contamination easier to trace through production.

Bales are arranged in stable stacks with inspection access. Clear separation from heat sources and vehicle exhaust helps protect the stock, while a simple lot sequence keeps older accepted material moving toward processing.

Remove Wrapping and Open the Bale

Twine is removed while the bale is still identifiable. The opener loosens the compressed straw into a controllable feed instead of allowing large lumps to drop into the cutting chamber.

A metered infeed also gives the operator time to notice an unusual object. The aim is a continuous supply of loose straw that the cutter can shorten evenly.

Primary preparation provides:

• Controlled release of compressed fibres
• A feed rate aligned with the downstream line
• Short stems suitable for fine preparation

Low-density straw needs generous passages and live discharge to avoid bridging.

Extraction contains cutting dust; accessible panels support routine cleaning.

Fine Grinding for Even Press Loading

A 132 kW hammer mill receives precut straw through a controlled infeed. The preparation section is selected for at least 5 T/H on accepted material, with a live-bottom buffer between grinding and the two presses.

The grinding section is selected by these operating characteristics:

Item	Selection basis	Check
Material	Precut rice straw	Clean fibres
Main drive	132 kW	Motor loading
Screen	4–6 mm starting screen; verify fibre profile	Sieve and visual check
Flow	Matched to press demand	Buffer level
Output	Uniform short fibre	Uniform fibre

Operators check the discharged fibre as well as the screen aperture, because long strands can pass through a hole end-first.

The material leaving preparation has the following handling priorities:

Feature	Desired condition	Operator response
Fine fraction	Controlled dust level	Review excessive regrinding
Short fibre	Consistent preparation	Maintain steady feed
Long fibre	Limited carryover	Check cutting and screen
Foreign matter	Excluded	Stop and investigate
Oversize	Separated	Return for preparation

A defined return point recovers clean process fines. Dirt removed at receiving leaves the process separately, protecting the fuel from unnecessary mineral contamination and the equipment from abrasive material.

Keep Prepared Straw Moving

A suitable buffer discharge prevents light fibres from forming a stationary bridge above an empty feeder. Level information and controlled withdrawal help the press maintain a steady load while the upstream equipment handles normal variation in bale feeding.

Densify the Straw into Industrial Fuel

The die works with the prepared straw’s moisture and fibre condition. Consistency at that point reduces the need for repeated adjustments and gives the operator a more useful relationship between motor current and output.

Both presses form nominal 8 mm pellets through separate metered feeders. They discharge into a combined cooling and screening route sized above the 4 T/H finished-product duty.

The pelleting arrangement is:

Parameter	Configuration	Purpose
Press type	Two MZLH678 ring-die presses	Agricultural residue duty
Die holes	Nominal 8 mm	Industrial fuel format
Main drive	2 × 200 kW	About 2 T/H selected duty per press
Die geometry	Straw-trial selection	Stable formation
Moisture at preparation	About 10–14%	Control feeding and binding
Nominal line duty	4 T/H	Qualified dry straw

Finished-product characteristics are defined for the industrial customer:

Property	Definition	Acceptance method
Diameter	Nominal 8 mm	Sample measurement
Length	10–30 mm target	Cutter and screen checks
Moisture	8–12% target after cooling	Cooled-product test
Particle integrity	Resists handling	Inspection and testing
Bulk density	500–650 kg/m³ working target	Measured bulk sample
Durability	Product-specific limit	Mechanical test
Ash	Agricultural fuel chemistry	Laboratory analysis
Heating value	Declared test basis	Laboratory analysis

Densification makes straw easier to store and convey, but the fuel retains the mineral character of the crop residue. Ash handling and combustion compatibility remain part of the product’s intended application.

Two eight-hour shifts allow fourteen net production hours, giving up to 56 tonnes/day at the nominal rate. At 12% incoming moisture, 10% product moisture and 3% dry-solids loss, accepted straw demand is about 59 tonnes/day. Collection plans therefore follow usable dry tonnes, not loose field volume.

Cool Continuously After the Press

Pellets pass into a counterflow cooler while the next material continues through the die. Continuous cooling frees the warehouse from the task of holding hot product on the floor.

The outlet is arranged for stable transfer to the screen and packing stations. In warm, humid conditions, cooling and storage protection work together to avoid delivering heat or condensation into a closed bag.

Removing loose fines after cooling improves the physical consistency of dispatches. It also reduces the amount of dusty material the customer handles at the receiving hopper.

Weigh, Close and Identify the Product

Two weighing-and-closing positions jointly handle at least 200 bags/hour in the 25 kg format. Production at 4 T/H requires 160 bags/hour, leaving handling margin for bag changes and pallet transfer.

Packing follows a clear sequence:

1. Select the agreed 25 kg or 50 kg format
2. Fill to the specified net weight
3. Close and identify the production batch
4. Move the bags into the released-stock area

Bulk supply is an alternative where customer access and unloading equipment suit it. Protected transport keeps the condition achieved at the factory from being lost on the delivery route.

Electricity, Operating Hours and Restart

Utility	Use	Design basis	Operating record
Electricity	Press and preparation	Demand and starting study	Production meter
Water	Staff and housekeeping	Separate clean supply	Metered use
Loader fuel	Bale and pallet handling	Vehicle hours	Daily log

Connected electrical duties are assigned by process section:

Group	Connected kW	Operating role	Sizing basis	Control
Primary cutting	55	Precut accepted stems	Bale opening and metered feed	Motor current
Fine grinding	132	Prepare fibre	At least 5 T/H on accepted straw	Sieve and buffer level
Two pellet mills	400	Shared pressing	4 T/H combined line duty	Individual feeder control
Extraction	22	Capture process dust	Duct and pressure study	Filter monitoring
Opening, cooling, conveying and packing	42	Material handling	At least 5 T/H downstream duty	Level interlocks
Lighting and office	5	Support	Separate circuits	Section meter
Total	656	Connected-load basis	Demand and starting study	Measure actual consumption

The two press motors total 400 kW; cutting and grinding add 187 kW. Extraction and downstream auxiliaries bring the connected-load basis to approximately 656 kW. The site needs a confirmed three-phase 50 Hz connection capable of the agreed running combination and controlled starts.

Routine water demand is about 1–2 m³/day for staff and housekeeping; fire-water provision is separate. Controls have short-duration continuity for an orderly stop. Production pauses during an extended supply failure unless a separately sized full-load generator is installed.

Engineering for a Seasonal Raw Material

Four decisions make the straw route more manageable for the operating team:

Dry-stock continuity. Covered storage connects harvest collection with production between deliveries.

Supplier stores bridge the harvest calendar. Factory procurement starts with available surplus, bale density, measured moisture and a truck-access plan, before committing to year-round delivery quantities.

Fibre preparation. Removing twine, cutting stems and controlling the fine-grinding result reduce bridging before the material reaches the two press feeders.

The preparation package brings together:

• An opener for compressed bales
• A cutter for long stems
• Fine grinding suited to straw
• Controlled feeders for the two working presses

Complete product handling. Cooling and screening turn press discharge into material ready for commercial packing.

Cooling, classification and bag handling remain inside the machinery scope.

A clear division of work. Nine positions per shift cover the factory. Collection contractors and transport staff remain outside the eighteen-person operating team.

Instruction is tied to the equipment and material:

• Recognizing unsuitable bales and maintaining clear storage access
• Preparing fibres and servicing the press under isolation
• Responding to interrupted feeding, overload or loss of power

Recording wear by operating hours and material batches helps procurement and maintenance work together. More soil in the incoming straw can mean more abrasive material passing through the preparation and pressing equipment.

Match the Pellet to the Combustion System

These are agricultural fuel pellets for suitable industrial equipment. Their sales specification addresses handling and fuel chemistry together, giving the buyer a clear basis for a combustion trial and subsequent deliveries.

Test	Reason	Release basis
Diameter	Fuel feeder compatibility	Buyer agreement
Length	Avoid bridging	Measured samples
Bulk density	Loading consistency	Bulk test
Durability	Handling resistance	Agreed test method
Fines	Dust and feeding	Screened sample
Moisture	Storage stability	Moisture analysis
Ash	Ash-removal capacity	Laboratory result
Heating value	Useful heat assessment	Declared basis
Sulfur	Combustion chemistry	Laboratory result
Chlorine and ash fusion	Deposit and corrosion assessment	Customer qualification

The choice between straw and wood fuel depends on the receiving equipment:

Comparison	Rice straw pellets	Clean wood pellets
Ash behaviour	Agricultural minerals require assessment	Different feedstock chemistry
Fuel value	Measured for the straw batch	Measured for the wood batch
Handling	Densified fibrous fuel	Densified woody fuel
Application	Compatible industrial furnace	Buyer and appliance specification

For an industrial boiler, ash quantity is only part of the discussion. Deposits, ash fusion and the cleaning arrangement also influence performance. A useful trial follows the fuel through feeding, firing and ash removal rather than stopping at a heating-value result.

RICHI MACHINERY

Turning Industrial Trials into Repeat Deliveries

The Bago–Yangon trading area gives the processor a route to industrial users, while incoming straw collection remains close to the farming districts. Pelleting improves outbound density; the economics of collecting loose residue still depend on a practical radius.

Commercial development follows four priorities:

• Available surplus. Farm collection is based on straw that can be released after other uses and soil-management needs are considered.
• Useful fuel value. Product comparisons account for moisture, ash and the customer’s combustion system as well as nominal heating value.
• A representative trial. The material offered to the customer should reflect the regular supply, not a specially selected sample unlike normal production.
• Repeatable handling. Consistent size and controlled fines make the delivered fuel easier to use in the customer’s feeding equipment.

Those priorities favour a dependable regional supplier relationship. The plant can build orders around what it can collect, process and deliver consistently, without relying on an uncertain export outlet to absorb every tonne.

The operating response to common constraints is:

Constraint	Practical response
Ash and deposits	Trial the fuel in a suitable industrial furnace
Harvest concentration	Covered supplier stock and delivery scheduling
Bulky incoming straw	Baling and short collection routes
Buyer qualification	Representative samples followed by controlled firing trials

Procurement, production and dispatch share one dry-stock and order schedule.
