What is Melt King®, the garbage drying and weight reduction device?

Melt King® is a "garbagedrying and weight reduction device" that reduces and sterilizeswaste by indirectly heating it at high temperatures and drying it while stirring it.

The waste is dried and reduced in volume using an environmentally friendly "indirect heating method," so the treated material can be recycled as fertilizer. In addition, since the treated material is combustible, it can be recycled as a fuel additive if pelletized.

*1: Some processed materials cannot be used.

By introducing Meltoking®, it is expected that there will be benefits such as a reduction in CO2 emissions and fuel consumption generated during waste disposal and transportation, making a significant contribution to realizing a carbon-free society and achieving the SDGs.

There are two types of Melt King®:the​ ​DNX series, which is effective for treating raw vegetables and food waste with high moisture content, and the MD series, which can safely treat infectious waste such as disposable diapers. They can be used both indoors and outdoors.

× Fuel is required to transport the waste, and greenhouse gases such as CO2 are generated during transportation and processing.

× Waste disposal costs are high

○ By reducing waste volume, fuel and CO2 emissions for transporting waste will be reduced.

○ Reduce waste disposal costs and reuse of treated materials

Features of Melt King®

Sterilize and reduce waste to 1/5 to 1/50

The air in the reduction/sterilization room is blocked and the moisture in food residue and infectious waste is evaporated using indirect heating, resulting in sterilization and reduction.

Depending on the water content, it is possible to reduce the drying weight to 1/50 at maximum.

処理コストの大幅削減

By reducing the amount of waste, we can reduce the amount of waste generated and cut processing costs. Since all operations except for the input and output of waste are fully autonomous driving there are no operating costs.

Environmentally friendly processing method

Since the waste is not directly burned using an indirect heating method, there is no scattering of dust and no generation of dioxins.
In addition, our unique deodorizing technology significantly reduces the odor of the steam after treatment, and the operation noise is quiet.

 

The Melt King® MD series has been introduced to hospitals in Kawasaki City.
By installing the optional demineralization unit, the allowable concentration limits for designated exhaust gas substances other than dioxins are cleared based on the strict standards set by Kawasaki City.

Processing flow

① After throwing in the waste, turn on the operation switch.

② The area around the heating chamber is heated by a burner, which indirectly heats the waste (food waste, infectious waste, etc.) that is put into the heating chamber.

3) By controlling the heating temperature and stirring, the waste is dried and broken down into small pieces.

④ The odors contained in the evaporated water are deodorized in a deodorizing chamber with a high-temperature heat storage structure and then discharged.

⑤ Cooling stop When cooling down to the set temperature, it will stop automatically.

Recycling of processed products

Unlike general incinerators, waste is not burned (=no oxidation reaction), so the treated product does not turn into ash, but becomes a combustible solid that retains its original energy. Therefore, it can be recycled into RDF (Refuse Derived Fuel) solid fuel, fertilizer and feed.

 

■ Examples of in-house utilization of processed products

①Melt King® is used to dry and reduce vegetable waste from food factories.
2) Use the treated products as fertilizer for your own fields

Remote monitoring of processing status and visualization of CO2 reductions

By remotely monitoring data processed by an AI-equipped edge computer on the cloud, it is possible to visualize the amount of waste disposal and CO2 reductions on a daily basis. We also support standardized data output such as monthly detailed reports.

Furthermore, vibration data can be analyzed using AI to predict malfunctions in advance, supporting timely maintenance.

 

In addition, by installing an optional uninterruptible power supply, the cooling operation can be completed normally even during a power outage, which allows it to be used in areas with poor power supply conditions.

System configuration

Introduction example

Melt King® has been introduced in a variety of locations, with the DNX series being used in food processing plants, resort facilities, golf courses, and employee cafeterias, while the MD series is used in medical institutions and nursing homes.

Meltking® Introduction Benefits | DNX Series CO2 Emission Reduction Effect

The table below shows the calculated CO2 emissions when food waste is collected, transported, and incinerated as is, and when food waste is dried and reduced in weight using Meltoking®, and then the residue is collected, transported, and incinerated. By using Meltoking®, it is possible to reduce CO2 emissions per ton of food waste by approximately 74%. *2
