Kitchen Waste Reduction Machine
CRO-300S three-phase separation - oil, water and solid residue
The CRO-300S kitchen waste reduction machine handles the step most composters cannot: separating kitchen waste into oil, water and solid residue before anything else happens to it. It shreds and dehydrates 150-300 kg per hour, extracts oil automatically for recycling, drains water, and discharges residue - which is what keeps a commercial kitchen compliant with HACCP standards and keeps grease out of the drains. Pair it with an electric composter and the two together form a complete on-site loop.

What it solves
- Grease and oil entering drains from commercial kitchen waste
- Wet, mixed kitchen waste that no downstream process can handle cleanly
- HACCP compliance pressure in canteens and hot pot restaurants
- Manual sorting and straining of waste by kitchen staff
Key benefits
- 150-300 kg/hour throughput in a 920 x 690 x 1100 mm footprint
- Three-phase separation of oil, water and solid residue in one pass
- Self or manual oil discharge for waste oil recycling
- Automatic spray rinsing, water replenishment and drainage
- Intelligent heating with an oil-full alarm
- Automatic residue discharge - no manual strainer emptying
- 220 V, 50 Hz supply; 3000 W with heating, 1500 W without

Who it is for
Commercial kitchen operators who need oil and water out of the waste stream at source - for compliance, for drain protection, and to make whatever comes next work properly.
Where it is used
- Canteens, commercial kitchens and hot pot restaurants
- Street food stalls and small-to-medium catering businesses
- Factory and corporate office catering operations
- Public institutions consolidating kitchen waste before composting
Quality control
Separation performance, oil discharge and alarm logic are run on test before shipment. The rinsing and drainage circuit is pressure-checked, and the machine is delivered with the specification sheet matching its serial unit.
Customisation
Throughput within the 150-300 kg/hour band, oil discharge mode and heating configuration are specified to the kitchen's duty cycle. Tell us the covers per service and the waste profile and we will confirm the configuration.
How it is operated
- Install in the back of house near the waste collection point on a 220 V supply
- Feed kitchen waste into the machine through the service period
- The machine shreds, dehydrates and separates oil, water and residue automatically
- Collect extracted oil for recycling - the oil-full alarm signals when
- Let residue discharge automatically for composting or collection
- Run the automatic spray rinse at the end of service
How it compares
The CRO-300S is pre-treatment, not composting. Where the CR series decomposes waste into fertilizer and the CRH-10 dries it, the CRO-300S separates it. Sites with heavy oil loads usually run the CRO-300S ahead of a composter rather than instead of one.
Frequently asked questions
What does three-phase separation mean here?
The machine splits kitchen waste into three streams - oil, water and solid residue - so each can be handled correctly instead of being sent out as one wet mixture.
How much can it process?
150-300 kg per hour, which covers most canteen and restaurant service peaks.
Does it help with HACCP compliance?
Yes. Automatic oil and water separation is what allows kitchen waste handling to be documented against HACCP standards.
What happens to the extracted oil?
It is discharged - automatically or manually - and can be collected for waste oil recycling.
How much power does it draw?
3000 W with heating and 1500 W without, on a 220 V, 50 Hz supply.
Does kitchen staff have to clean strainers?
No. Residue discharge and spray rinsing are automatic - that is the point of the design.
Can it replace a composter?
No. It prepares waste. Many customers run the CRO-300S in front of an electric composter so the composter receives separated, dewatered solids.
