  • Patent number: 11116230
    Abstract: The present invention relates to a method for three-dimensional microwave air-jet drying of persimmon slices, comprising steps of grading and cleaning, slicing, microwave heating, steam de-astringency, hot-air reverse primary drying, negative-pressure intermittent secondary drying, cooling and packaging. In the present invention, high-temperature (60-70° C.) high-pressure annularly sprayed citric acid and 40% alcohol vapor (rotating at 360°) are adopted to remove astringency of persimmons, wherein high temperature causes more intense Brownian motion of liquid molecules; high pressure improves permeation and diffusion speed of de-astringency liquid in the persimmon slices; citric acid plays a membrane breaking role on persimmon cell membranes; and 40% alcohol vapor is allowed to rapidly diffuse into cells, so that tannin is polymerized into insoluble gel from a soluble state, thereby achieving a uniform and rapid de-astringency effect.
