Energy-saving multi-box tremella steam drying plant and process

Abstract

The invention discloses an energy-saving multi-box tremella steam drying plant and process. The energy-saving multi-box tremella steam drying plant consists of a steam boiler, a heat exchanger, a drying box and pools. The process comprises the following preparation steps: taking out tremella and cleaning in one pool; soaking the cleaned tremella in another pool for 1-1.5 hours; and finally, placing the soaked tremella in the drying box to dry for 2.5-3 hours, wherein the steam pressure is controlled at about 2.5kg, at the beginning of the drying, the temperature rises rapidly, and afterwards,the temperature is kept at 70-80 DEG C. According to the invention, the dried tremella is white and bright, the shape of the tremella is loose and neat like peony. The process disclosed by the invention has the advantages that fuel is saved, preparation time is shortened, work efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to edible fungus drying equipment and technology, in particular to an energy-saving multi-cabinet white fungus steam drying equipment and technology. Background technique [0002] Tremella fuciformis Berk, also known as Tremella fuciformis Berk, is a well-known edible and medicinal fungus in my country. It has been listed as one of the four treasures of "ginseng, velvet, swallow, and ear" in history, and was once used as a court tribute. Tremella is the flagship product of edible fungus in Gutian County. In 2004, "Gutian Tremella" was approved by the State Bureau of Quality Supervision as a "National Protected Product of Origin". In 2011, Gutian tremella production reached 27,000 tons (dry products) and earned more than 40 million US dollars in foreign exchange through export. It was exported to 27 countries and regions in Europe, America and Southeast Asia. It is one of the unique traditional export materials in Gutian County. ...

AI Technical Summary

Problems solved by technology

First, the utilization rate of heat energy is low, the drying time is long, usually 8 to 10 hours, and the drying cost is high, so it is not suitable for the tremella production area of ​​factory, large-scale and standardized production

Second, the sulfur dioxide content of dried white fungus products exceeds the standard, which seriously affects the export of white fungus products and food safety.

Because the drying stove basically uses a self-made dryer head to build a drying room, the dryer head often leaks air, and the drying air enters the drying room, causing the sulfur dioxide content of the dried tremella to exceed the standard.

The third is to pollute the environment, causing Mao Dun disputes and fire hazards
