Drying Technology of Edible Fungi

Almost all edible mushrooms, such as Lentinus edodes, fungus, Flammulina velutipes, hericium Erinaceus, straw mushroom, Pleurotus ostreatus, mushroom, Tremella fuciformis and so on, can be made into dried products. Drying processing can be divided into sun-drying and hot air drying. More cloudy and rainy days in spring, Lentinus edodes, fungus is often baked, summer and autumn hot sun, is the straw mushroom production season, often drying. Hot air drying, not affected by environmental conditions, can be carried out in four seasons, suitable for all kinds of mushrooms, and the quality of drying is good. The quality of drying is also closely related to mushroom picking, grading, shearing, cleaning, slicing and so on. Lentinus edodes should be graded according to size, shape and thickness, flower mushrooms and thick mushrooms should be separated separately, and high-foot mushrooms, deformed mushrooms and diced mushrooms should be treated as external treatment. Then cut off the base of the stalk (fungal foot), leaving the length of the stalk 2 to 3 centimeters, at the same time, remove weeds and sawdust, but do not use water. Drying method: dry the graded fresh mushrooms in the sun for one day, then dry them with charcoal fire, or dry them continuously in the sun, never pile them up before drying. If you use charcoal fire to dry, the temperature should be from low to high, start at 20: 30 ℃ for 6 hours, then bake for 2 hours with 50% 60 ℃ for 3 hours until the stalk is completely dry. The dried mushrooms are turned by hand until they are clattered and crushed. After cooling, they can be collected in plastic bags. When baking, we should pay attention to charcoal or coal fire can not have smoke and peculiar smell, strictly prevent broken bacteria fall into smoke, otherwise affect the quality of dried mushrooms. In order to distribute the heat evenly, an iron plate can be covered on top of the fire. where there are conditions, a blower can be used to send hot air or steam pipes to send warm air to dry. Dried straw mushroom, should choose the same size of the egg, remove the sediment, with a knife from the base of the cross cross cut two knives, cut the egg into three long, into four pieces, called orchid mushroom after drying. There is also a knife longitudinally cut from the side, leaving the wrapped foot uncut, or cutting two pieces, which can be dried on the cement floor after cutting. Dried mushroom egg slices should be sliced longitudinally and dried with hot air to ensure quality. Pleurotus ostreatus, Pleurotus ostreatus and Flammulina velutipes can all be dried or dried.
