Simulation and Development of a Kelp Drying Prototype Using Existing Equipment

Bull kelp plays a crucial role in Alaska’s marine ecosystem and has significant economic potential due to its applications in food, pharmaceuticals, and biofuels. Bull kelp holds a strong position in the market thanks to the Alaskan value-added seaweed company, Barnacle Foods. However, the high moisture content of harvested kelp presents substantial challenges in drying and storage, as existing methods often require specialized equipment that is not always accessible or affordable in southeast Alaska. This limitation prevents Alaska from tapping into larger kelp markets, adversely impacting the economic viability of kelp producers and limiting the industry’s ability to meet the growing global demand for high-quality, sustainable seaweed products.

There is a critical need for an innovative solution that leverages existing equipment to develop an efficient drying and storage technique tailored to Alaska’s unique marine environment. Sea Quester Farms aims to develop an innovative kelp drying prototype to enhance the efficient drying and storage of bull kelp, utilizing equipment already transported across southeast Alaska. By utilizing a container-based freezer retrofitted with a heat pump unit, the system ensures efficient, low cost drying through the capture and utilization of waste heat from adjacent storage freezer units.

This project will enhance the economic viability of kelp producers, support the growing demand for sustainable seaweed products, and contribute to the sustainable development of Alaska’s mariculture sector. In partnership with Spruce Root, Sea Quester Farms aims to widely disseminate the project’s findings, fostering sustainable practices and driving growth in the Alaskan mariculture industry.
