This invention relates to the field of tobacco processing technology, and particularly to a sweet-scented granular tobacco stem and its processing technology. The processing technology includes the following steps: S1, Preparation of coarse granular tobacco stem: The tobacco stem raw materials are screened by size, washed, stored, pressed, cut once, and cut twice to obtain coarse granular tobacco stem; S2, Popping the stem in a popcorn machine: The coarse granular tobacco stem is fed into a popcorn machine for roasting, kept warm and pressurized, and then quickly depressurized to normal pressure to obtain granular tobacco stem with a uniform microporous structure; sieving; S3, Flavoring the tobacco stem: The sieved granular tobacco stem is fed into a roasting equipment, a natural sweetener is added, and roasting is performed, controlling the moisture content between 12-14%, to obtain the finished sweet-scented granular tobacco stem. The sweet-scented granular tobacco stem obtained by this invention has a regular and uniform shape, rich flavor layers, and a long aroma retention time. The overall quality of the tobacco stem is significantly improved, and it can be effectively applied to cigarette production to enhance the competitiveness of cigarette products.

The intelligent down feather extraction and purification system comprises a filter box, a disinfection box and a drying box which communicate with one another, a first down feather inlet is formed in the lower portion of the filter box, a first down feather outlet is formed in the upper portion of the filter box, and a second down feather inlet and a first auxiliary suction opening are formed in the upper portion of the disinfection box; the filter box is used for filtering down feather for the first time; the disinfection box is used for disinfecting, sterilizing and secondarily filtering the down feather; and the drying box is used for drying and filtering the down feather for three times. The first auxiliary suction port is connected with a suction device, the second down inlet is connected with the first down outlet through a pipeline, a sensor and a proportional control device are arranged on the pipeline, the sensor is used for detecting the gas flow rate in the pipeline, the proportional control device is in linkage with the sensor, and the proportional control device is used for controlling the size of an opening in the position where the proportional control device is arranged. And the aim of extracting down feather in stages is fulfilled while multi-stage filtering disinfection is ensured.

This application relates to the textile field, specifically disclosing a thermal insulation fabric and its production method. The thermal insulation fabric comprises, from the outside in, a PTFE garment film, an adhesive layer, a polyethersulfone / polyurethane mixed fiber wadding, a hollow PBT core-sheath composite fiber layer, an adhesive layer, and a polyurethane / zirconia aerogel composite fiber layer. The polyurethane / zirconia aerogel composite fiber layer is woven from polyurethane / zirconia aerogel composite fibers, which have a core-sheath structure. It is prepared by coaxial wet spinning of the sheath solution and the core solution, followed by impregnation in a tert-butanol aqueous solution, pre-freezing, and freeze-drying. The sheath solution is a polyurethane solution, and the core solution is a polyurethane solution containing zirconia aerogel powder, with a mass ratio of zirconia aerogel powder to polyurethane of 0.2-0.3:1. The thermal insulation fabric of this application has the advantages of good thermal insulation effect, high mechanical strength, high compression resilience, and relatively fluffy texture.
