Klinge Corporation delivered its Model CBU-30 container blast freezer unit to the Ministry of Marine and Fisheries of Indonesia (through PT Waisity Indonesia) for the Fishermen Empowerment project.
The CBU-30 is designed for quickly freezing cargo down to –60° C (–76° F). The ministry will be using the blast freezer to keep sushi-grade tuna at its required temperature.
Blast freezing tuna and other high-value fish to an ultra-low temperature of –60° C (–76° F) substantially reduces transportation costs as the fish can be transported by container ship rather than air-freighted. It allows for long-term storage of the tuna so customers can purchase as needed and no tuna is wasted. Tests have shown that shelf-life is increased when tuna is frozen to –60° C (–76° F) and thawed, at a time of the customer’s choosing, in a controlled environment.
The freezer container was delivered to the Port of Surabaya, where it then was transferred to the remote Banda Islands. Polly Katipana, the Indonesian agent and in-country project leader, noted that the newspaper in Ambon, part of the Maluku Islands (which includes the Banda Islands) published an article on the CBU-30 blast freezer recently. In the article, the governor of Maluku discussed the unit with the lead fisherman of the group using the container, who referred to it as a gift of the holidays.
Features of the blast freezer include:
•Two-step refrigerant system—One high-temperature system (two compressors) on R134a, and one low-temperature system (one compressor) operating on R23. The high-temperature system cools the condenser for the low-temperature system.
•High capacity—The CBU can be set to achieve the desired core temperature during either a 12- or 24-hour plus cycle. During this time, the unit will maintain a supply air temperature of between –30° C (–22° F) and –65° C (–85° F) depending on the required capacity needed for product freezing.
•Even temperatures throughout the cargo.
•Adjustable ceiling—spanning the entire container, it ensures maximum airflow across cargo. It can be adjusted easily by one person to a variety of different load heights.
