Porphyra is a coldwater seaweed that grows in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea). There are considered to be 60 to 70 species of Porphyra worldwide and seven around Britain and Ireland where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast. Porphyra is a chief source of plant-based vitamin B12.
Automatic drying equipment for laver
This utility model discloses an automatic drying and dehydration device for seaweed, relating to the field of seaweed dehydration technology. It includes a rotating shaft, which is rotatably mounted to the rear end of a drying chamber via bearings. A limiting plate is installed on the outside of the rotating shaft and welded to it. The device allows the rotating shaft to rotate by installing a drying basket, causing the seaweed inside the basket to rapidly dehydrate under centrifugal force, thus improving the drying efficiency. When the drying basket centrifuges the seaweed, the seaweed adheres tightly to the inner wall of the basket under centrifugal force. Because the drying basket has a mesh structure with many gaps, the seaweed adheres to the inner wall. Combined with the centrifugal force acting on the seaweed, this effectively overcomes the strong hot air blown by the hot air dryer, preventing the seaweed from flying around and breaking, thus allowing the seaweed to be dried at the highest speed.

Decorative sheet food and its manufacturing method
Conventional sheet foods, such as nori seaweed, are often manufactured in flat sheets. For decoration, some are printed or cut with a laser, or branded. These are post-processing of two-dimensional elements manufactured in flat sheets, and do not include three-dimensional elements that take into account the thickness of the sheet food. Furthermore, the increase in processes reduces efficiency and has an impact on the sheet food ingredients. [Solution] The present invention provides a decorative sheet food that is not processed after the processing into a flat sheet, but is processed simultaneously with the forming into a sheet. Using a dotted or embossed mold, a mixture of at least water or a binder solution is poured into the shredded food, and the mixture is controlled to create a watermark that creates shades of thick, thin, and plain areas in the sheet food material, thereby providing added value.
