Embodiment 1

[0017] A kind of sulfur-free Tremella drying production process, comprises following production process:

[0018] 1) Cut off the ear pedicles of white fungus, grade them according to size and flower shape, and dry them in batches during drying, which not only ensures the quality, but also improves the drying efficiency.

[0019] 2) Flower washing: Soak the graded white fungus in clean water for 5 minutes, then rinse with clean water once. The soaking time should not be too long, otherwise the flower shape will be too large, which will not be beautiful, and will affect the number of plates.

[0020] 3) Dehydration: Dehydrate the cleaned white fungus with a centrifugal dehydrator for 3 minutes to remove the water on the surface and crevices of the white fungus.

[0021] 4) Packing: The dehydrated white fungus is neatly placed on the material tray, and the entire tray is placed on the material cart, pushed into the vacuum low-temperature combined dryer, and the warehouse door is...

Abstract

The invention discloses a drying production process for sulfur-free white fungus and aims at providing a white fungus drying method which is low in energy consumption and sanitary. The technical essentials of the drying production process comprise the following steps in sequence: (1) removing stalks of the materials and classifying the materials; (2) washing the materials; (3) dehydrating the materials; (4) panning; (5) drying the materials under low-temperature vacuum environment in a combined manner; (6) drying the materials by hot air; (7) grading the dried materials; and (8) packaging and storing the treated materials. The key of the technology is that the vacuum low-temperature combined dying of the step (5) is completed by three steps. The drying production process disclosed by the invention belongs to the deep processing industry of agricultural products. Besides, the technical scheme disclosed by the invention is suitable for drying the white fungus, dehydrated vegetables and traditional Chinese medicines.

Description

technical field [0001] The invention provides a drying production process of white fungus, specifically, a drying production process of sulfur-free white fungus, which belongs to the deep processing industry of agricultural products. Background technique [0002] Fresh white fungus has a high moisture content (generally 75% to 80%). It is very difficult to store and keep fresh. Even if the conditions are suitable, it can only be stored for about two weeks. Dehydration and drying is an important method for the processing and storage of white fungus. "Gutian white fungus" is one of the important agricultural and sideline products for foreign exchange earning in Fujian Province, with an annual output of 8,000 tons of dry products, accounting for 80% of the country's total output, and its production and sales rank first in the world. At present, "Gutian white fungus" is mostly dried in a vertical airflow hot air drying room, but this method has problems such as uneven drying, ...
