We are a company that always strives to be the top in the field of drying and roasting.

Management Goals

As a micro-business-type regional company, we aim to be the "future engine of the region."

[Defining micro-businesses]
A small group of brains that cares about private life by cleverness, a local company that does not assume that it will technically run the cutting edge and grow.

Business Introduction

Development, design and manufacture of A and D (hot and cold air drying) using microwave heating together

We propose a new drying method using microwave heating and A and D.

1.Seafood dryer (drying temperature: 20 to 40°)
2.Drying dryer (drying temperature: 30 to 60°)
3.Industrial dryer (drying temperature: 40 to 80°)
4.Drying dryer (drying temperature: 100 to 140°)

Development, design, and production of microwave decompression dryer sugokan

The microwave decompression dryer dries vegetables and fruits with high sugar content, such as strawberries, at room temperature (3-5 hours at room temperature or less).
We produce dried products with little drying shrinkage by reducing the loss of color, flavor, and ingredients.

Development, design and production of grain roasting equipment such as wheat

We develop, design and manufacture roasting equipment such as barley tea, brown rice and healthy tea.
The roasting device for barley tea by numerical management enables roasting of 1 ton of wheat per hour even with the operation of inexperienced people.

Development, design and production of muzuk processing equipment

We have developed a muzuk processing facility at the request of Okinawa Prefecture.

◆We design and manufacture equipment to match the processing capacity.
Washing seawater sterilization equipment, cleaning equipment, transport ation equipment, visual sorting equipment
・Stirring and mixing equipment, lightweight filling equipment, drying equipment

Dedicated machines for niche industries

We are developing dedicated machines and planning and developing labor-saving equipment.

1.Blenders for other products
Development of blenders that reliably blend other varieties
2.Color sorting equipment
Development of a device for sorting by color using a camera
3.Sound difference sorting device
Development of a device for sorting by frequency of collision sound
4.Packaging-related equipment
Development of raw material supply and post-packaging processing equipment
5.Development of dedicated machines
Development of dedicated machines for small production items


Technology development and acquisition of industrial property rights using the public certification system

Certification of new cooperative business plan (Ministry of Economy, Trade and Industry)

2007July, "Development and commercialization of paper tubes, scallops and muzuk drying methods using hot air drying and microwave heating"
【Cooperation Destination】JF沖縄漁連(Okinawa),日本紙管工業株式会社(Osaka Prefecture),株式会社ウイング(Shizuoka Prefecture),株式会社しんや(Hokkaido)

・The world's first air flow-in-type microwave decompression dryer has been put to practical use. We have also developed an efficient drying method for combining microwave heating with A and D (hot air and cold air drying).
Through the new joint project plan, we have created a network connecting Okinawa Prefecture and Hokkaido based in Shizuoka Prefecture.

Accreditation of the Agricultural, Industrial Cooperation Plan (Ministry of Economy, Trade and Industry, Ministry of Agriculture, Forestry and Fisheries)

2008September "Product development and sales of semi-life type using Miyakojima Muzuk"
【Cooperation Destination】Miyako jima Fisheries Cooperative Association, Miyakojima City, Okinawa Prefecture

・We commercialize and sell "Green Muzuk", which is made from raw mok, which is not salted.

Accreditation of regional industrial resource utilization plan (Ministry of Economy, Trade and Industry, Ministry of Agriculture, Forestry and Fisheries)

2014October "Development and sales of decompression tea machines, and decompression fermented tea commercialization project utilizing tea leaves in the middle of the mountainous area"

・We develop a vacuum tea machine and produce fermented tea in a new flavor of green tea, oolong tea style, and tea style made from Shizuoka tea.
