Abstract

The invention discloses a high-quality bamboo fungus drying method, and belongs to the technical field of agricultural product drying. The method comprises three stages of high-temperature large-air-volume moisture removal and shaping, medium-temperature large-air-volume moisture removal and color fixation and low-temperature small-air-volume moisture removal and tempering, and high-quality dry bamboo fungus products are obtained through stage-by-stage heat pump drying in the three stages. High-temperature large-air-volume moisture removal drying is adopted in the early stage of high moisture, most moisture is removed within a short time, and large-air-volume moisture removal enables the dictyophora indusiata to keep a good shape; medium-temperature large-air-volume dehumidification drying is adopted in the middle stage, so that the dictyophora indusiata can keep good color and luster; and low-temperature and small-air-volume dehumidification and drying are adopted in the later stage, so that the bamboo fungus is tempered in the heat pump dryer, and the internal temperature and humidity exchange of the bamboo fungus becomes more uniform. The bamboo fungus prepared in the invention is free of peculiar smell, free of sulfur, pure white in color and low in drying cost.

Description

technical field [0001] The invention belongs to the technical field of drying agricultural products, and in particular relates to a drying method for high-quality bamboo shoots. Background technique [0002] Dictyophora, also known as bamboo fungus and bamboo ginseng, are common and edible. There are 4 kinds: long skirt bamboo fungus, short skirt bamboo fungus, spiny bamboo fungus and red bamboo fungus. Flower fungus, slightly resembling net-shaped dry white snakeskin, it has a dark green cap, a snow-white cylindrical stipe, a pink egg-shaped receptacle, and a delicate white mesh skirt around the top of the stipe Spreading downward from the mushroom cap, it is known as "Snow Skirt Fairy", "Flower of Mountain Treasures", "Flower of Fungi", "Queen of Fungi". It is rich in 19 kinds of amino acids needed by the human body, fungal proteins, polysaccharides, vitamins and trace elements, etc., and is delicious. [0003] Traditional dried bamboo fungus is mostly prepared by natura...
