The processing of bamboo fungus mainly adopts the drying method:

1. Harvesting

It only takes a few hours from the stem to the mature fruit body of bamboo fungus. Fruiting bodies mature almost every day during the mushrooming season, so they need to be checked frequently and harvested in time. Dictyophora fungi are delicate and must be handled with care when harvesting, taking care to keep the skirt and stipe intact. If the harvested fruiting bodies are contaminated with spores or soil, use a soft brush lightly dipped in water to clean them. After the cap is washed to remove residual spores, and the fungus holder is washed to remove surface soil, it is placed in a bamboo basket together with the stem, skirt, etc. for later use.

2. Drying

① Sun-drying: Place the fresh fruit bodies of Dictyophora fungus flatly on the cotton sheet one by one, expose them to the sun, and make them symmetrical from side to side. . After the fungus skirt has shrunk, it is moved to an overhead window screen to dry in the sun. Or directly place the bamboo fungus on a clean cement floor to dry in the sun. The dried flowers are beautiful in shape, white in color, free of oil stains and of good quality. In case of short-term rainy weather, you can lay cotton sheets on a multi-layer bamboo frame in the windward place and then dry it. Pay attention to ventilation to prevent mildew. When it is sunny, move it out immediately and expose it to the sun as before. It can also be combined with drying, and then use electric heat to dry it when it is half dry. The moisture content of dried bamboo fungus should be 12% to 13%. If the moisture content is too low, it will be easily crushed by crushing. If the moisture content is too high, it will be susceptible to insects and mildew.

② Drying: Bamboo fungus can easily absorb smoke and odor in the air, so it is best to bake it directly without coal or charcoal. When baking in a flue-type drying room, the drying room can be preheated to 40°C, and when the air humidity becomes low, the baking screen can be put in. The drying room should be equipped with a blower to ventilate and remove moisture in a timely manner. After drying, take out the dried product together with the baking sieve, wait for 20 minutes to soften before packaging.

③ Dehydration machine drying: Place the bamboo fungus in layers according to size, thickness, dry and wet. The starting temperature is 35°C to 40°C. After increasing the air volume and maintaining it for 1 hour, gradually increase the temperature to 50°C to 55°C for 1.5 to 2 hours. Adjust the dehumidification device to fully circulate the hot air. Each temperature rise and fall must be checked in advance to avoid water leakage and blackening of the stipe. When the bamboo fungus feels dry to the touch and turns white, heat it up to 60°C and keep it for 30 minutes. Take it out, let it soften slightly and then pack it.

3. Grading packaging

There is no unified grading standard for bamboo fungus. Grading standards vary slightly from place to place. For example, the grading standards for short-skirted bamboo fungus are: the first-grade stipe is more than 12 cm long, more than 3 cm thick, the moisture content does not exceed 13%, milky white, complete flower shape, no mildew, no insects, no odor and impurities ; The second grade stipe is 10 to 12 cm long, 2.5 cm to 3 cm thick, with a moisture content of no more than 13%, milky white or light yellow, with a complete flower shape, no mildew, insect spots, odor and impurities; third grade The stipe is 8 to 10 cm long, 1 to 2.5 cm thick, has a moisture content of no more than 13%, is light yellow or light khaki, has about 10% broken stipes and broken skirts, has no mildew spots, no insects, and no odor. and impurities; the stipe of the substandard product is less than 8 cm long, dark in color, with broken stipes, skirts or incomplete fruiting bodies, no mildew, no odor, less impurities, and a moisture content of no more than 13%. Packed according to standard grading. First put the dried bamboo fungus into a food plastic film bag, seal the bag mouth, then put it into a wooden box or corrugated carton, and store it in a dry and moisture-proof warehouse with good facilities.
