Embodiment 1
[0036] The drying method step of embodiment 1 thermosensitive reducing agent is as follows:
[0037] The heat-sensitive reducing agent modified white sugar reducing agent has an initial moisture content of 35%, a light yellow liquid, and a reduction potential of 970. Add 20kg of sorbitol to 980kg of reducing agent, stir well; let it stand for 30 minutes, blow in cold air for convection, make the reducing agent material condense and remove surface water; cut the condensed reducing agent into pieces and mash, flat Lay it on the conveyor belt, control the thickness at 40mm, control the vacuum degree in the microwave drying chamber at 0.06 MPa, microwave power at 2kW, temperature at 60°C, and dry for 8 minutes. At this time, the moisture content of the reducing agent material is 10%; turn off the microwave drum Hot air convection, let the reducing agent material cool for 5 minutes, turn on the microwave again, control the temperature at 90°C, dry for 2 minutes, and then crush and ...
Embodiment 2
[0038] The drying method step of embodiment 2 thermosensitive reducing agent is as follows:
[0039] The heat-sensitive reducing agent thiourea dioxide derivatives containing sulfonic acid groups has an initial water content of 38%, light yellow liquid, and a reduction potential of 970. Add 30kg of 2-butene-1,4-butanediol dibutyrate to 970kg of reducing agent, and stir thoroughly; it is left to stand for 30 minutes, blowing in cold air for convection, so that the reducing agent material is condensed and the surface water is removed; The condensed reducing agent is cut into pieces and crushed, spread on the conveyor belt, and the thickness is controlled at 50mm; the vacuum degree in the microwave drying chamber is controlled at 0.05 MPa, the microwave power is 2kW, the temperature is 50°C, and dried for 6 minutes. The moisture content of the reducing agent material is 14%. Turn off the microwave and let the reducing agent material slow down for 5 minutes. Turn on the microwave ...
Embodiment 3
[0040] The drying method step of embodiment 3 thermosensitive reducing agent is as follows:
[0041]Heat-sensitive reducing agent Sulfonated aldehyde ammonia reducing agent has an initial water content of 40%, a white emulsion, and a reduction potential of 985. Add 25kg of glycidyl isocyanurate to 975kg of reducing agent, stir well; let it stand for 30 minutes, blow in cold air for convection, make the reducing agent material condense and remove surface water; cut the condensed reducing agent into pieces and pound Crushed, lay flat on the conveyor belt, the thickness is controlled at 45mm; the vacuum degree in the microwave drying chamber is controlled at 0.1 MPa, the microwave power is 3kW, the temperature is 60°C, and dried for 10 minutes. At this time, the moisture content of the reducing agent material is 15%; Turn off the microwave and let the reducing agent material slow down for 5 minutes, turn on the microwave again, control the temperature at 85°C, and dry for 3 minut...
