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.

This application relates to a method for preparing a toughened, low-shrinkage unsaturated polyester resin bulk molding compound. The bulk molding compound is extruded using a screw extruder. The screw extruder includes a frame, an extrusion module, and an extruder head. The extruder head is equipped with a filter structure, which includes a filter screen with a plurality of filter holes and a drive component. The filter screen is installed inside the extruder head and is rotatable. The drive component includes a toothed ring fixed to the filter screen and a drive gear driven by a motor installed outside the extruder head. One side of the toothed ring is exposed outside the extruder head, and the drive gear meshes with the toothed ring. This application uses a drive gear to drive the rotation of the toothed ring, thereby causing the filter screen to rotate inside the extruder head. This solves the problem of a fluid dynamic "dead zone" easily forming in the contact area between the filter screen edge and the inner wall of the extruder when using a fixed filter screen structure, reducing the possibility of scorching caused by the retention of high-viscosity thermosetting materials.

This invention relates to the C10L9 / 10 field of IPC classification, and particularly to a coal-saving catalyst for thermal power plants and its preparation method. The coal-saving catalyst, by mass percentage, comprises the following raw materials: 5-20% gluconate, 10-20% diol, 5-13% citrate, 3-10% oxygen-containing free radical organic matter, 1-3% molasses, 0.1-1% dispersant, and deionized water to make up the balance. The coal-saving catalyst prepared in this application has excellent effects in promoting coal combustion, reducing burnout, improving combustion efficiency, and reducing pollutant emissions. It also effectively enhances the mutual wetting effect of the coal system and strengthens the penetration of the coal-saving catalyst within the coal system. It is suitable for promotion in the thermal power field and has broad development prospects.
