Processing steps of bamboo fungus
1 Bamboo fungus pretreatment
In order to ensure the grade quality of bamboo fungus, it should be harvested in time. The bamboo fungus planted by the ecological cultivation technology of fungus grass has thick and tall stipe and bright and crispy skirt. Before the bamboo fungus is baked, place the bamboo fungus neatly on the baking mat, and use a knife to gently cut the white skin at the bottom of the bamboo fungus stalk.
2 layer the bamboo fungus
Place the bamboo fungus in layers. Be careful not to stack them to prevent from affecting the drying quality of the bamboo fungus. Bamboo fungus buds will continue to open after being picked or after standing. Pay attention to the cleanliness of the sorting site because it is difficult to clean the white mushroom leaves after they are stained with mud and dust.
Bamboo fungus drying process
1.Check the status of the equipment, and set various parameters such as target humidity, target temperature, dehumidification mode, drying time, and dehumidification on & off time for each time zone. The overall design principle of equipment parameters is that start drying from low temperature to high temperature mode, and then turn to low temperature mode.
2.It is better to dry the bamboo fungus at low temperature such as 40°C, then the temperature can be slowly raised to 50°C and keep for about 4 hours. Afterwards, the temperature will drop to 40°C and continue to bake for about 3 hours. You should check whether the dehumidification of the heat pump dryer is normal. It is normal that condensed water is continuously discharged in the first 5-6 hours.
3.Grading and packaging the dried bamboo fungus. After drying, take it out and let it cool down for 20-30 minutes. After the cells become soft, they should be graded for packaging. The drying rate of fresh bamboo fungus is generally 26-28%. The water content of the bamboo fungus processed by this way will not exceed 13%. After drying, the bamboo fungus is milky white, with complete flower shape, no peculiar smell and impurities, and the storage period can be as long as about one year.
