5 T/H Plant Based Cat Litter Production Line in Malaysia

RICHI MACHINERY

Johor Gives the Plant a Short Raw-Material and Distribution Radius

Johor works for this project because agricultural trading, food processing, pet-product distribution and cross-border logistics are all available within a manageable radius. The plant does not rely on a claim that Malaysia has unlimited low-cost waste; it relies on specific supplier contracts for materials that can meet a repeatable cat-litter specification.

1. Pet-product demand. The customer already sold into channels connected with pet stores and distributors, giving the new plant a realistic route to market without assuming every household would switch from clay litter.

2. Feedstock diversity. Bran, starch residues, dewatered okara and bamboo powder can all contribute to a plant-based formulation, but each needs separate receiving and storage rules.

3. Import substitution potential. Local production can reduce long inbound lead times and give distributors more flexibility on bag size, fragrance and private-label specifications. The project does not assume a fixed percentage price advantage over imports.

The commercial model is therefore based on confirmed product specifications and distribution margins, not on one retail-price comparison.

Phase 1 Was Sized Before Phase 2 Was Promised

The customer leased an existing industrial property in Johor Bahru with about 2,000 m² for production plus separate warehouse and office space. He entered the project with trading experience but no cat-litter manufacturing history, so the first line had to be operable by a newly trained team.

The initial idea was smaller, but process testing showed that moisture reduction, drying and multi-grade packaging would dominate the fixed equipment regardless of whether the forming section was 2 T/H or 5 T/H.

The expansion strategy was therefore split into two investment stages:

• Phase 1: Completed 5 T/H line with about 17,000–18,000 T/Y practical saleable output depending on formula and dryer load.
• Phase 2: Reserved expansion to a second production line only after feedstock, power, warehouse space and sales justify the additional capacity.

This phased structure limits the risk of building 10 T/H of forming capacity before the dryer, transformer and sales channels are ready for it.

Wet Okara Changes the Entire Material Balance

The Phase 1 plant uses several material families sourced through Johor and nearby supply channels. The annual plan is built around dewatered feedstock rather than assuming fresh tofu residue can enter the pellet mills directly.

Material	Annual usage (tons)	Source	Cost per ton (RM)	Notes
Wheat bran	4,000	Regional flour mills	Contract-specific	Dry fibrous base
Corn bran	3,000	Feed and grain processors	Contract-specific	Dry fibrous base
Tapioca starch residue	2,500	Starch processors	Contract-specific	Conditioned/dewatered before use
Bamboo powder	2,000	Qualified local/import suppliers	Contract-specific	Texture and odor-control blend component
Soybean residue (okara)	8,000	Tofu and soy processors	Contract-specific	Supplier-side dewatering required before receiving
Other additives (binder, color)	500	Approved suppliers	Contract-specific	Formula-dependent inclusion

Total Phase 1 purchasing volume is about 20,000 T/Y on the dewatered or conditioned basis; saleable output is lower after final drying and screening.

The highest-risk material is okara. Fresh tofu residue can arrive at 70–75% moisture, which is unsuitable for storage or direct pelleting. Suppliers therefore perform primary dewatering before delivery, and the cat litter plant completes final moisture reduction as part of its process. This moisture strategy is also what separates a commercial tofu cat litter plant in Malaysia from a dry-bran pellet line: fresh okara cannot be treated as ready-to-form feedstock.

Bamboo powder is used selectively rather than as a marketing ingredient at a fixed percentage. Its low bulk density and bridging tendency affect hopper design and feeder settings, so inclusion depends on flowability and the target litter texture.

RICHI MACHINERY

Forming Drying and Cooling Must Be Balanced as One System

Plant-based cat litter is lighter and more fragile than mineral litter. The cat litter making machine section therefore has to work with controlled moisture and binder distribution rather than forcing an unstable wet mix through the die.

Here’s what we supplied for the eco cat litter manufacturing line:

Equipment	Qty	Specification	Notes
Feed hopper with dust hood	2	2 m³ each	For manual bag dumping
Hammer mill (fine)	1	55 kW, 1.5mm screen	Grinds wheat bran and corn bran
Hammer mill (coarse)	1	37 kW, 3mm screen	For bamboo powder and dry okara
Bucket elevator (1#)	2	DTG36/23, 10m lift	Stainless steel cups
Mixer (ribbon type)	4	SLHY2.0, 2 tons/batch	7.5 kW each
Bucket elevator (2#)	2	DTG36/23, 8m lift
Permanent magnet	2	TCXT20	10,000 Gauss
Cat litter pellet machine	2	110 kW, 4mm die	Ring die type
Scraper conveyor	8	Various lengths	For inter-stage transport
Counterflow cooler (primary)	4	SKLN2.5, 2.5 m²	Cools pellets after pelleting
Rotary drum dryer (electric)	2	90 kW, 3m length	For final moisture reduction
Counterflow cooler (secondary)	4	SKLN2.5	Second cooling after drying
Vibrating screener (primary)	4	SPJH110x2, 2 decks	Separates fines and overs
Vibrating screener (secondary)	4	SPJH110x2, 3 decks	Final grading
Dust collectors (pulse-jet)	18	Various sizes	TBLMa-6, TBLMa-4
Packaging machine	3	5-15 kg bags	Automatic filling, 8 bags/min
Air compressor	2	15 kW, screw type	For pneumatic controls

The two-stage cooling arrangement exists because drying and forming are separate thermal steps. Pellets are first stabilized after forming, then dried toward storage moisture, then cooled again before screening and packaging.

Final moisture is controlled around 6–10% according to formula and packaging requirement. The second cooling stage prevents warm dry pellets from creating condensation after sealing.

Eight Stages Protect Clumping Quality and Low Dust

The production manager was trained to treat moisture and fines as process variables, not just final laboratory results.

Stage 1 – Receiving and Grinding

Raw materials arrive in 20-25 kg bags (wheat bran, corn bran, bamboo powder, okara). Workers dump bags into two feed hoppers – one for coarse materials (bamboo, okara) and one for fine materials (bran). Dust hoods capture the dust at the dump point.

The coarse hammer mill (3mm screen) grinds bamboo and okara. The fine hammer mill (1.5mm screen) grinds the bran. Ground material is pneumatically conveyed to bins above the mixers.

Stage 2 – Batching and Mixing

The control system calls up a recipe. The client has five different formulas: standard wheat-based, corn-based, bamboo premium, okara economy, and a “clumping” formula with added guar gum.

Each batch is 2 tons. Mixing time is 6 minutes. The mixers are ribbon type – gentle enough to not break the bamboo fibers but thorough enough to distribute the binder evenly. Water is added during mixing (about 8% of batch weight) to bring moisture to 18-20% for pelleting.

Stage 3 – Pelleting

The mixed mash drops into a surge bin, then feeds into two pellet mills. Together they provide about 5 T/H of installed forming capacity. Die size is selected by litter grade rather than a single universal setting.

Freshly formed pellets are still warm and moisture-rich, so they are not ready for final packaging at this stage.

Stage 4 – Primary Cooling

Hot pellets fall into the first set of counterflow coolers. Ambient air (about 30°C in Johor) is pulled up through the pellet bed. Cooling time: 15 minutes. Exit temperature: 35-40°C. Moisture: 12-14%.

Stage 5 – Drying

Final drying is the critical moisture-control step. Drying duty changes with okara inclusion, incoming dewatering level and target finished moisture rather than one fixed 150°C air-temperature claim.

Why electric? The industrial site did not have a convenient gas connection, so electric drying was selected. Transformer capacity, startup current and demand charges were therefore checked as part of the final utility design.

Stage 6 – Secondary Cooling

Hot, dry pellets come out of the dryer at 55-60°C. The second set of coolers brings them down to within 5°C of ambient (about 35°C in Johor’s tropical climate). This prevents condensation inside the bags.

Stage 7 – Screening and Grading

The product passes through two vibrating screeners. The first screener (2 decks) removes fines (which go back to the mixer) and overs (which go back to the hammer mill). The second screener (3 decks) separates pellets into three size grades:

• Fine (1-2mm): Sold as “rapid clumping” for kittens
• Medium (2-4mm): Standard litter
• Coarse (4-6mm): Economy litter (less dust, less clumping)

Stage 8 – Packaging

Each grade goes to a separate packaging machine. Most Malaysian pet stores want 5kg, 7kg, or 10kg bags. The automatic scales fill, heat-seal the bags, and date-code them. Palletizing is manual for now – the client plans to add a robot in Phase 2.

Commissioning Exposed Power Dust and Flow Problems

Three commissioning issues were more useful than any marketing claim because they showed where plant-based materials differ from conventional feed pellets.

Problem 1: Dryer startup overloaded the available electrical supply.

The 90 kW mesh belt dryer created a high startup load against the industrial park transformer. The commissioning response was to sequence motors and heating circuits so the full drying load did not start at once.

Problem 2: Early pellets generated too many fines.

Binder distribution, moisture and die loading were adjusted together. The plant does not rely on one fixed guar-gum percentage or one conditioning temperature for every formula.

Problem 3: Bamboo powder bridged in the hopper.

Hopper vibration and feeder geometry were adjusted so the low-density fibrous material entered the mixer at a steadier rate.

The operating lesson was simple: stabilize feedstock condition before increasing line speed.

Quality Control Centers on Moisture Fines and Clumping

The client set up a small QC lab in the office area. Basic equipment – moisture meter, sieve shaker, pH meter, and a homemade clump test rig.

Test	Target	Frequency	Method
Moisture content	6-10%	Every hour	Moisture meter
Pellet durability	≥92%	Every shift	Tumbling test (home-built)
Fines percentage	≤2%	Every hour	Sieve analysis (2mm screen)
Clump strength	Holds together when wet	Daily	Simulated urine test
pH	6.5-7.5	Weekly	pH meter
Dust (airborne)	Low	Monthly	Simple settle plate

The clump test is their own invention. They pour 50ml of water onto a 100g sample of litter, wait 10 seconds, then lift the clump with a spatula. Good litter holds together. Bad litter falls apart. Simple, effective.

Dust and Wastewater Are Managed as Separate Environmental Streams

For this cat litter manufacturing plant in Malaysia, the main environmental issues are dry organic dust, dryer exhaust, domestic wastewater and packaging waste. Permit limits remain site-specific and should be checked against the actual Johor facility approval.

Air emissions: Local extraction and dust collectors operate at bag dumping, grinding, transfer and screening points. Performance is verified against the plant’s permit rather than a generic nationwide concentration quoted out of context.

Wastewater: The process does not use a wet washing stage. Water added to formulation is largely removed again during drying; sanitary wastewater follows the industrial park collection route.

Solid waste: Clean recoverable fines return to production when quality permits, while packaging waste is separated for recycling or approved disposal.

Environmental compliance is treated as a continuing operating responsibility rather than a one-time inspection claim.

RICHI MACHINERY

Operating Cost Is Tracked by Formula Not by a Guaranteed Payback

The plant’s commercial performance is evaluated by formula, packaging and channel. Raw-material moisture, electric drying and bag format can move unit cost materially from one product to another.

Operating cost categories for the standard bran-based litter:

Cost component	RM/kg	USD/kg
Raw materials (wheat bran, corn bran, binder)	0.68	0.15
Electricity (140 kWh/ton at RM 0.35/kWh)	0.05	0.011
Labor (12 operators, RM 2,500/month each)	0.07	0.015
Packaging (7kg bags, printed)	0.18	0.04
Maintenance (dies, hammers, bearings)	0.04	0.009
Depreciation (equipment over 8 years)	0.08	0.018
Rent (warehouse + office)	0.03	0.007
Overhead (admin, logistics)	0.05	0.011
Total	1.18	0.26

Selling prices are contract-specific and vary by formulation, bag size, private-label requirement and distributor margin.

• Standard bran-based litter: priced by confirmed wholesale contract
• Bamboo-containing premium blend: evaluated separately because bamboo and packaging costs are higher
• Okara-rich economy blend: priced only after drying cost and dust performance are confirmed

Gross margin is calculated from actual invoices and utility bills, not a fixed RM/kg assumption.

Monthly production: limited by dryer load, changeovers and confirmed sales
Gross margin: calculated from actual formula, packaging and channel rather than a fixed published figure

Loan and working-capital cost: handled in the customer’s own financial model rather than published as a fixed project assumption

Net monthly result: not stated as a fixed value because raw-material contracts, electricity, product mix and finance cost change over time

Phase 2 should proceed only when the first line has enough confirmed demand, power headroom and raw-material supply to support it.

Private Label and Regional Retail Are the Most Flexible Sales Channels

The Johor plant is positioned for several channels without depending on invented named-customer orders:

• Pet stores and regional distributors in southern Malaysia
• Online and private-label retail channels that require smaller bags and differentiated formulas
• Selected regional export opportunities where registration, labeling and logistics are confirmed

Customer acceptance is tracked through repeat orders and product tests:

The standard grade is evaluated for balanced clumping, low dust and bag stability.

The bamboo-containing grade targets buyers who value plant-based texture and odor-control positioning.

The okara-containing grade is released only when drying and fines control meet the same storage requirements as the other products.

Singapore and other nearby markets may support premium products, but export pricing is treated as a separate commercial calculation rather than an assumed margin.

RICHI MACHINERY

Expansion Depends on Dryer Power and Warehouse Space

Phase 2 remains a reserved expansion path. Before adding a second line, the customer needs to confirm transformer capacity, dryer duty, raw-material contracts, warehouse turnover and actual market demand.

Planned additions:

• Second hammer mill line (dedicated to bamboo powder)
• Additional 1,000 m² warehouse space (adjacent building)
• Automatic palletizer (reducing labor by 4 people)
• ISO 9001 certification (for export to Singapore and Brunei)

The team is also evaluating lower-binder and more dispersible formulations, but any “flushable” claim requires product testing and local wastewater guidance before it is used commercially.

RICHI Design Starts With the Material Moisture Map

Plant-based litter projects differ by fibre source, moisture, binder system and local packaging. A Malaysia cat litter factory using okara cannot be designed like a dry bran-only line.

What we offer:

• Material-specific design. Wheat bran behaves differently than cassava fiber. Bamboo powder behaves differently than okara. We test your materials in our lab before we design your line.
• Dual cooling/drying systems. Cat litter needs lower final moisture than animal feed. We know how to size dryers and coolers for tropical climates.
• Gentle handling. Plant-based pellets are fragile. Our elevators, conveyors, and mixers are designed to minimize breakage.
• Local support in Malaysia. We have a service engineer based in Johor (he trained at our Qingdao factory for 3 months). Spare parts are stocked in Port Klang.
• Bahasa Malaysia documentation. Control panel labels, manuals, and safety signs are in English and Bahasa Malaysia.

Not what we do: We don’t just sell you a pellet mill and disappear. We design the whole line – from the bag dumper to the palletizer. And we stay until you’re making good product.

Malaysia Cat Litter Projects Need Feedstock and Market Proof at the Same Time

The plant-based pet-products market offers room for local manufacturing, but the business case should be built from confirmed raw materials, finished-product tests and distributor demand rather than a generic Southeast Asia growth percentage.

Why local production makes sense:

• Use agricultural byproducts only after checking moisture, spoilage risk and consistency. Low purchase cost does not guarantee low processing cost.
• Import substitution is not automatic. Local producers still compete on clumping, dust, odor control, packaging and delivery reliability.
• Plant-based positioning can increase exposure. The product still needs measurable performance before “eco” claims create repeat sales.
• Export is a separate compliance project. Labeling, claims, registration and freight have to be checked market by market.

The completed 5 T/H plant gives the customer enough industrial scale to test multiple grades without committing to an unproven 10 T/H final buildout.

If you have dewatered okara, bran, starch residue or bamboo fibre, start with moisture, dry-matter balance, clumping target and package size before selecting the forming and drying system.

Shipping and Logistics

All equipment for this project shipped from Qingdao Port, China. For Malaysia, the nearest major port is Port Klang (near Kuala Lumpur). Shipping takes 10-14 days. From Port Klang, trucking to Johor Bahru takes about 4 hours. For Phase 1, we shipped one 40-foot HC container and one flat rack (for the dryer). Total shipping cost was $8,500.

For Phase 2, the client is consolidating equipment into two 40-foot containers to save on freight.

RICHI MACHINERY

One More Engineering Check Before Expansion

The first line should prove stable dryer load, finished moisture, fines level and repeat sales before the plant doubles forming capacity.

That is a better expansion signal than a temporary order spike.

If you are considering a 5 T/H eco cat litter production line in Malaysia, send the incoming moisture of each material, annual dewatered tonnage, target litter size, clumping requirement, packaging mix and available transformer capacity.
