One can obtain a patent for invention in a laboratory dedicated blade drum dryer. The patent is registered by Henan Zhongyan Industrial Co., Ltd.
It is understood that the bladed drum dryer includes a frame, an outer cylinder, an inner drum, a heater, a controller, and a frequency conversion motor with a gearbox; the middle portion of the outer cylinder is rotatably mounted on the frame. The inner cylinder of the drying wire is rotatably disposed in the outer cylinder, and both ends of the drying wire inner cylinder protrude outside the outer cylinder. The inner wall of the drying wire inner cylinder is provided with a plurality of rows of baffles arranged in parallel in the axial direction, and the left end of the outer cylinder is two. The side is fixed with a supporting roller; there is a thermal insulation layer between the outer cylinder and the drying wire inner cylinder; the thermal insulation layer is evenly distributed along the axial direction of the drying inner cylinder and close to the inner wall of the drying cylinder; The tank wall below the outer cylinder is provided with a groove, the heater is arranged in the tank and the heating surface of the heater is facing the outer wall of the drying inner cylinder; the output shaft of the frequency conversion motor is connected with the drying wire inner cylinder through a gear transmission mechanism. After drying with the dryer, the dried leaflets are relatively soft, the curling degree is good, and the phenomenon of parallelism is small. After the cigarette is rolled into a cigarette, the sensory appearance is the same as that of a normal production product.
EDTA is mainly used for Water Treatment, as an additive to Detergent, chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis.
1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre poiduction.
2. Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3. Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4. Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl imide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5. Textile dyeing and printing: EDTA will promote color ability of the dyestuff and brightness of the dyed fabric.
