FISH VACUUM DRYING METHOD Russian patent published in 2020 - IPC F26B5/04 F26B3/30 

FIELD: food industry.

SUBSTANCE: invention relates to food industry, in particular, to dried fish production method. In method fish before drying is cut into plates with thickness of 1–2 cm and is laid on tray of drying chamber. Then drying process is started with application of variable residual pressure. Infrared lamps are used as heat source. Heating temperature of the product throughout the drying process does not exceed 45 °C. Heat flow density makes 4–6 kW/m².
