Motion type drying equipment and method for biologically refined herbal fibers
Technical Field
The invention relates to the field of herbal fiber production. In particular to a biological refined herbal fiber movement type drying device and a method.
Background
The application history of the herbal fiber is long, and the process for extracting the natural fiber from the herbal fiber raw material adopts a method of retting natural flora under natural conditions. However, the traditional process occupies a large water surface (the contradiction between the traditional process and the water source competing with the breeding industry is increasingly prominent in recent decades) and takes a long time, so that the quality of the product is extremely unstable. After finding out the proper degumming strain, a modern production process for biological degumming of the fibrilia is formed, which generally comprises the procedures of pretreatment, inoculation, fermentation, inactivation, cleaning, oil soaking, drying and the like, for example, the fibrilia raw material is dried, the fibrilia is led to pass through a closed drying box body, and the drying box body is generally heated by adopting a steam pipe heat dissipation mode, so that the moisture of the fibrilia is evaporated. The heating mode not only needs to be provided with a high-power boiler and consumes a large amount of fuel, and has serious environmental pollution, but also has large heat loss and low heat efficiency because the distance between the boiler and the dryer is far, and in addition, the whole drying device needs to occupy a large area because of heat dissipation of the steam pipe.
