You can confirm the short-time and high-quality heating with microwaves. - Sample submission experiments: We will conduct tests using the raw materials and samples sent by the customer. The results will be compiled into data and reported later. ● For more details, please contact us or refer to the catalog.

Radio wave heating is a method that generates heat from within the material itself, as opposed to external heating (such as hot air or high room temperature), causing the material to rise in temperature. When items at sub-zero temperatures are heated, it results in a defrosting process. When items at room temperature are heated, it is a heating process, and further heating can lead to drying and sterilization processes. Rapid heating can result in puffing processes. Once equipment is installed, it can operate for many years. Our company provides safe and reliable devices tailored to the installation location and frequency characteristics, based on years of experience and delivery records. The application range of radio wave heating in food processing is expanding in areas such as confectionery, baking, and the use of raw materials and products in general food items. *For more details, please contact us or refer to the PDF materials.*

High-frequency dielectric heating and microwave heating are collectively referred to as [electromagnetic wave heating]. This technology provides outstanding contributions that bring immeasurable benefits, such as improving the efficiency and rationality of heat treatment processes, enhancing the working environment, and reducing labor.

By performing secondary sterilization through heating with a microwave sterilization device, we achieve long shelf life for food, contributing to the reduction of food waste and addressing SDGs challenges. 【Implementation Examples】 〇 Sterilization of grilled fish: Can be sterilized with short heating time 〇 Sterilization of boiled shirasu: Can be sterilized even after packaging 〇 Sterilization of prepared foods: Long shelf life for products through secondary heating sterilization Unlike external heating, microwaves heat uniformly from inside the product, preventing excessive heating of the surface. The device will be custom-made according to the installation environment and space. ● For more details, please contact us or refer to the catalog.

◆ Microwave heating allows for simultaneous temperature rise and stabilization of temperature both internally and externally. ◆ Since it is a short-time process, it is also possible to handle small quantities of various types. We offer a variety of equipment, from continuous systems for large-scale processing to small batch systems for small-scale processing. For more details, please contact us or refer to the catalog.

High-frequency heating, unlike external heating such as gas flames, allows for internal heating using radio waves, enabling quick and uniform heating and drying. 【Advantages of High-Frequency Heating】 - It is less likely to compromise flavor compared to gas flames, allowing for high-value-added heating and drying. - Inline processing is possible through continuous treatment. - The heating and drying time can be adjusted by changing the set output. - The equipment operates solely on electricity, requiring no water or air, making it easy to set up. 【Testing Available】 - On-site experiments: We will conduct tests at our factory with the customer's presence. You can confirm the quick and high-quality heating with the high-frequency heating equipment. - Sample submission experiments: We will conduct tests using the raw materials and samples sent by the customer. Results will be compiled and reported later. For more details, please download the catalog or contact us.

The microwave drying device, unlike external heating, heats the product uniformly from the inside using electromagnetic waves, ensuring that flavor and quality are not compromised even after sterilization. 【Examples of Implementation】*Increasing attention in recent years 〇 Drying of fresh bread crumbs 〇 Drying before powder processing 〇 Puff drying of processed foods 〇 Drying of grains The device will be custom-made according to needs such as installation environment, space, and operator operations. 【Testing Available】 ・On-site experiments: 　We will conduct tests at our factory with the customer's presence. 　You can confirm the short-time and high-quality drying using microwaves. ● For more details, please contact us or refer to the catalog.

As a new heating process, how about "microwave heating"? It has a wide range of applications, including "heating," "drying," and "sterilization and disinfection treatment," and we can propose equipment types tailored to your processing needs. Microwave heating allows for high-efficiency heating in a short time by heating from within the material, and it is used for heating hollow fiber membranes used in dialysis treatment, as well as other medical products, resins, and fibers. Since there is no need to heat the surrounding air, energy efficiency can also be improved. It can be used in conjunction with other heat sources (such as hot air or steam). Additionally, there are methods to increase heating efficiency by reducing pressure within the furnace according to the situation. We will propose the optimal equipment type from various types of microwave heating devices.

In most manufacturing processes of various products, heat treatment for heating and drying is involved. Common heating methods include hot air or flames from combustion, steam, or electric heating elements. This is referred to as "external heating" because heat is gradually transferred from the outside to the inside through conduction. On the other hand, high-frequency dielectric heating fundamentally differs from external heating, as the heated object itself becomes the heat source and is heated from the inside, hence it is called "internal heating." Internal heating allows for very efficient heating in a short time compared to external heating! There is growing attention on microwaves to improve the time efficiency of heating and drying in food manufacturing processes. 【Technical Documents & Comprehensive Catalog】 ■ Microwave heating, which is being applied in various industrial fields ■ Features of microwave heating ■ Microwave application devices, etc. In addition to improving the efficiency of heating processes and energy saving, the development and proposals of clean advanced technologies essential for the creation of future environmental industries, from high-frequency heating to microwave heating, will be addressed by Yamamoto Vinita, who walks alongside the history of radio wave heating. *For details, please download the PDF or contact us directly.
