Kitchens where the drains never clog
In ordinary food waste processors, wastewater drains slowly, so residue builds up in the pipes and sewers clog easily. Hayeon's patented drainage system pushes wastewater out with force, cutting down on clogs, odors and backflow.

Our patented forced drainage system
With gravity drainage, processed water trickles out slowly. Grease and fine particles stick to the pipe walls and settle on the bottom, scale forms, and the line clogs. Hayeon uses a pump at the drainage stage to push processed water out at the right pressure. The water moves faster and spends less time in the pipe, so deposits don't build up.
Load the food waste
Open the lid and put kitchen food waste straight in.
Microbial fermentation
Microbes multiply quickly and ferment the food waste, sharply reducing its volume.
By-product recovery
The fermented by-product is collected separately and can be used for compost, feed or raw material.
Forced drainage with our patented system
The patented drainage system pushes the separated wastewater out with force, in line with Korea's Wastes Control Act, to keep sewer lines clear.
About 70% of food waste processor service calls
are clogs, backflow and odor
With gravity drainage, wastewater flows out slowly, so residue inevitably builds up inside the pipes. Eventually the sewer clogs, dirty water backs up or smells, and someone has to call for service.
Hayeon's patented forced drainage system tackles this cause at the root. It has even cleared sites that had chronic sewer clogs.
Share of service calls caused by food waste processors
that come from sewer clogs, backflow and odor
Real clog and backflow cases from sites using gravity-drainage processors
| Item | Typical gravity drainage | Hayeon patented forced drainage |
|---|---|---|
| Wastewater discharge | Trickles out slowly by gravity | Pushed out with force by the patented system |
| Sewer clogs | Residue builds up and clogs often | Less buildup, fewer clogs |
| Backflow and odor | Clogs cause backflow and smells | Far less worry about backflow and odor |
| Service frequency | Frequent pipe-related call-outs | Few pipe-related service calls |
| Pipe costs | Costs for drain clearing and high-pressure jetting See a ₩40 million damage case (Korean) → | Lower pipe maintenance costs |
| Breakdown management | Reported and repaired after it breaks | Checked early and fixed remotely through KT IoT |
We know before it breaks, and fix it remotely
An IoT monitoring service connected over KT's LTE network watches each installed processor in real time. We spot warning signs early, inspect before a breakdown, and fix some problems remotely without a site visit.
- Real-time status monitoring
Operating status is checked around the clock over KT's LTE network. - Early fault detection
When warning signs appear, we contact you and inspect before it breaks down. - Remote response
Some settings and fixes are handled remotely to cut downtime.
Power-off detected → service center calls you first → breaker and power check guidance or on-site visit
A lineup built for each site
From restaurants and cafeterias to department stores, shared buildings and produce processing plants, we manufacture equipment matched to each site's volume and installation conditions.

Something wrong? Check these first
Self-help steps by symptom for the HYN series (HYN70L · 110L · 150L · 170L · 220L · 300L).If the steps don't solve it, call the service center at +82 1661-3145.
- Turn the power off before cleaning or inspecting.
- Don't touch the power cord with wet hands.
- Keep your hands out of the rotating drum and mixer.
- Don't open the front cover while the machine is running.
- Don't load food waste while the machine is faulty.
Choose a symptom
It won't turn on
Check these first
- Check whether the display (LED panel) on the front of the machine is lit.
- If this machine's breaker in the building's distribution box has tripped, switch it back on.
- Make sure the plug is pushed all the way into the outlet. A loose plug can make the power unstable and trip the breaker.
- Look for kinks, crushing or worn insulation on the power cord.
- With dry hands, unplug and replug the cord, then plug another device into the same outlet to check it has power.
- If you are using a power strip or extension cord, remove it and use a grounded outlet of 10A or more for this machine only.
- Open the large panel at the lower front (outer case) and switch the machine's breaker back on if it has tripped.
Call for service right away if
- The breaker trips again right after you switch it on
- The outlet has power but the machine won't turn on
- The cord insulation is worn or you smell burning
Frequently asked questions
What food waste can go in?
OK to load
Do not load
If a banned item goes in, switch off and take it out.
Can I leave the door open for more than 10 minutes?
