About COWPIGGY
Application engineering.
Qualified manufacturing.
One accountable team.
COWPIGGY is a Hong Kong-based industrial technology company specializing in application engineering, equipment configuration and global sales.
We analyse the operating requirement, engineer the configuration and coordinate production through qualified manufacturing partners in China.
How we work →- 01Analyse the application
- 02Engineer the configuration
- 03Coordinate manufacturing
- 04Inspect and deliver
Start with the product, not the machine
What are you sorting?
Every product behaves differently in feeding, inspection and ejection. We use your material and defect profile to narrow the machine architecture before discussing a model.
02
Plastics & recycling
Colour separation and visible contamination in selected recycled material streams.
03
Ore & minerals
Optically distinguishable colour, brightness and surface variation after feed review.
04
Beans & seeds
Off-colour product, impurities and visible shape-related defects.
05
Tea & botanicals
Foreign material, colour anomalies and inconsistent leaves or herbal pieces.
06
Other bulk materials
Send photos, videos and a representative sample for an optical-separation feasibility review.
YOUR MATERIAL / YOUR DEFECT STANDARD
A better first conversation
Send the material first.
Choose the machine second.
A model name alone cannot tell you whether feeding is stable, the defects are visible or the target output is realistic. Your sample gives the project a measurable starting point.
- 01What must be removed?
Show the accepted product and the reject standard.
- 02What must be protected?
Define acceptable carryover and product damage concerns.
- 03What must the line deliver?
Share throughput, feed conditions, voltage and available space.
Reference machine range
Scale the system to the line.
These reference configurations show the available scale. Final model selection follows a material and throughput review.
01 Standard chute series
Flexible capacity for established processing lines.
A multi-chute optical sorter configured around product type, defect visibility and plant conditions. Suitable as a reference platform for rice, grains, beans and selected nuts.

- CPS-V384
- Reference channels
- 384
- Final selection
- After material review
STANDARD / 06 CHUTE
HIGH CAPACITY / 12 CHUTE
02 High-capacity chute series
More channels for higher-volume production.
A wider platform for larger processing lines. Capacity still depends on the material, defect ratio, feed uniformity and the required sorting accuracy.

Need another format?
Belt, plastic, mineral and application-specific systems can be reviewed after we understand the material and handling requirements.
Compare all sorting systems →Technology that answers a production question
See more. Decide faster. Eject precisely.
The useful question is not whether a system contains advanced components. It is how each component helps separate your accepted product from your reject standard.
Industrial imaging
High-resolution image capture gives the controller more visual information about colour, shape and surface differences.
Adaptive illumination
Lighting is configured to improve the contrast between good product, defects and foreign material.
Recognition algorithms
Colour, shape, area and texture information can be combined to support more specific sorting rules.
Fast pneumatic ejection
The decision is translated into a timed air pulse that removes the targeted item from the product stream.
Stable feeding
Consistent distribution helps the inspection zone see individual product more clearly and supports repeatable output.
Connected support
Available remote functions can support operation, maintenance, upgrades and fault diagnosis after commissioning.
Sorting principle · simplified
One pass.
Five coordinated actions.
ACTIVE STAGE01 / Feed system
The feed system distributes the material into a stable, controllable stream.
From inquiry to operating line
A decision process your team can follow.
Each stage closes a specific uncertainty before the project moves forward—from material feasibility to commercial configuration and delivery planning.
- 01Application brief
Material, defect photos, throughput, voltage and plant context.
- 02Sample review
Confirm defect visibility, handling needs and the test objective.
- 03Configuration
Recommend machine format, channels and supporting requirements.
- 04Commercial offer
Align scope, documentation, shipment terms and installation needs.
- 05Delivery support
Coordinate production, export logistics and commissioning preparation.
Beyond optical sorting
Build around the wider production line.
Automatic packaging
Stick pack, sachet, VFFS and integrated packaging configurations.
Industrial material handling
Electric pallet trucks, stackers, counterbalance forklifts and reach trucks for warehouses and industrial operations.
Request a configuration
Show us the material.
We’ll map the next step.
You do not need to know the model. Share what your operation processes and the result you need; COWPIGGY will review the brief and tell you what information or samples are required next.
✓ Useful defect photos or a short line video
✓ Target capacity and current process
✓ Power supply and destination country
