PURPOSE:To facilitate the evaporation of water and removal of oil from the food fried under reduced pressure, by drying the fried food continuously under reduced pressure to the final water content. CONSTITUTION:A food raw material is fried automatically and continuously in frying oil maintained at a specific temperature with the conveyors 4a, 4b, etc. The frying is carried out to an extent to leave the water sufficient to splash the attached oil by the impact of the evaporation, i.e. several-about 20%. The semi-finished fried product is taken out of the oil continuously by the conveyors 4a, 4b, etc. The frying chamber is sealed air-tightly, and maintained at a definite degree of vacuum by the vacuum pump 1, etc. The generated steam is removed from the system as water or ice by the cooling device. The frying chamber is furnished with a sensor to detect the oil temperature and an auxiliary heating means such as infrared heater 5, microwave generator 6, etc. |
