The "Proton Defroster" is a system that can defrost delicate fish roe, such as mass salmon roe and red salmon roe, which are sensitive to temperature changes, in a high-quality and hygienic manner. In conventional methods, high temperatures and long operation times were unavoidable, leading to uneven defrosting. Additionally, tanks placed outdoors were difficult to clean and had hygiene issues, such as mold growth. The "Proton Defroster" uses a steam boiler as its heat source, allowing for uniform defrosting in a low-temperature, high-humidity environment with 100% humidity. It eliminates uneven defrosting and prevents color fading and flavor deterioration. With efficient heat transfer through the latent heat of steam condensation, the color of the fish roe remains vibrant, and the flesh stays firm during defrosting. As a result, in the cleaning and trimming processes (deveining), the roe is less likely to be crushed, enhancing the effectiveness of enzyme treatment, improving yield, and increasing work efficiency. The Proton Defroster, which preserves color, shape, and texture without compromising freshness and quality, greatly contributes to quality control and product value enhancement in the seafood processing industry. *We have a test machine ready and look forward to your visit.

Challenges Before Implementation A company that manufactures and sells confections using juice was naturally thawing fruit juice stored in drums. The thawing process (natural thawing) took 3 to 4 days in summer and over 10 days in winter, occupying a large space within the factory during that time. Additionally, it required personnel to manage the process, which significantly constrained productivity. There were also concerns about the deterioration of the freshness and color of the juice, leading to a demand for a more efficient and high-quality thawing method. Effects of Implementation The implementation was based on confirming the effectiveness through actual machine tests conducted in the Shinagawa test room beforehand. It was confirmed that the thawing of drums with the Proton thawing machine could be completed in one day year-round. Therefore, a customized proposal for the introduction of a large differential pressure rapid thawing machine and storage facility was made, maintaining high quality without compromising the freshness and flavor of 100% juice. Additionally, the need for a dedicated thawing space was eliminated, allowing personnel to be reassigned to other departments, which significantly improved productivity. The thawing machine received high praise for achieving both quality preservation and efficiency simultaneously. *We are preparing a test machine and look forward to your visit.

Proton Engineering's proton thawing machine achieves speed through its patented technology of "100% humidity." It focuses on "latent heat" as an energy source at low temperatures and high humidity. Since latent heat stores a significant amount of thermal energy, it serves as an efficient thawing method. The thawing program offers 10 patterns, and data retrieval for operating temperatures is possible. After thawing, it automatically switches to refrigeration mode, completing the process from "thawing to refrigeration" with a single unit. There is also a holiday mode available, allowing it to be used as a refrigerator. By maintaining an environment with a relative humidity of 100%, speedy thawing is achieved even at low temperatures (10°C). The standard models are 40kg/B (dimensions: 830W × 800D × 1950H) and 160kg/B (1750W × 790D × 1950H), with custom designs available for larger units ranging from 500kg for on-site installation. Developed by engineers well-versed in freezing technology, this product is highly regarded as thawing equipment that balances quality and efficiency. A test room is available. Please consider introducing our product. Contact: info@proton-eng.co.jp
