Microwave Extraction System

Features of the Microwave Extraction System

By irradiating raw materials such as citrus peels with microwaves, moisture and essential oils inside the material are vaporized, efficiently extracting and collecting aroma components. Our proprietary vacuum distillation technology minimizes thermal damage, bringing out the rich, natural fragrance of the ingredients.

High Extraction Quality

Low-temperature extraction captures heat-sensitive fragrance components without letting them escape, allowing high-quality essential oils and hydrosols (aromatic waters) to be extracted.

Suitable for Food Applications

Because it uses an additive-free process, naturally derived essential oils and hydrosols can be obtained. It can be used for food applications and labeled as extracts or liquid extracts.

High Efficiency with Low Operating Costs

Extraction can be performed in a short time, significantly reducing running costs compared to boiler-type steam distillation systems.

Environmentally Friendly

Being fully electric, it emits no CO2 at the production site.

Case Studies

Waste Reduction

Effective Utilization of Unused Resources

Tosayama Factory Cooperative

Essential oils and aromatic waters are extracted from previously underutilized materials, such as post-juicing peels and non-standard produce. As a new way to utilize unused resources, this leads to commercialization and added value.

Adopted as a Tool for Original Product Development

Beverage Manufacturer

Introduced to develop custom-flavored beverages. It helps in developing new products to gain a competitive edge over rivals.

Used for Seasoning Development

Food Manufacturer

Used to concentrate tomatoes at low temperatures to develop seasonings such as sauces. Because additive-free processing is possible, products can be developed to meet the modern demand for additive-free foods.

Frequently Asked Questions

How much raw material is required for sample testing?

For citrus oil extraction tests, the estimated amount is about 5 kg for small units and about 25 kg for large units. Since this varies depending on the characteristics of the material, please feel free to contact us first with questions like "I only have a small amount" or "Can we test with a different material?"

Are sample tests fee-based?

Yes, extraction tests using actual raw materials are fee-based. The cost varies depending on the amount of raw material, equipment used, test content, and frequency, so please contact us individually for details.

What are the running costs during operation?

Efficient microwave heating significantly reduces energy loss. We can provide estimated running costs and ROI simulations tailored to your raw materials and machine model, so please contact us individually.

How long does it take from initial inquiry to delivery?

It varies depending on your consultation details and specifications, but since this equipment is custom-made to customer requirements, it takes a certain period from initial discussions to delivery (approx. several months to 1 year).

How is operational training handled, and what support is available in case of trouble?

Upon delivery, specialized staff will provide on-site instruction on operating procedures and routine inspections. In the event of trouble, support staff will respond promptly.

Is after-sales service available?

Yes. We recommend an annual periodic inspection, and the first-year inspection is free of charge. From the second year onward, charges apply, but we will propose the optimal maintenance plan based on the condition of your equipment.

Are there any legal regulations?

Under the Radio Law, filing an "Application for Approval of High-Frequency Equipment" is required. Please submit the application to your local Bureau of Telecommunications in accordance with your installation timeline.
