Embodiment 1
[0019] After centrifugal separation, the obtained sodium gluconate crystal is 2000kg, the moisture content is 2.5%, the air flow feeder is used, and the flow rate is 50m / s and the temperature is 35℃ by using the fan 2-1, the filter 2-2 and the heat exchanger 2-3. The wet crystals after centrifugal separation are sent to the down-rotating cyclone separator 2-4 by the hopper of the airflow conveying feeder. After the materials are suspended in the separator, the crystals enter the vibrating fluidized bed from the outlet at the lower end of the separator. 2-8.
[0020] After the wet crystal material of sodium gluconate enters the fluidized bed, it is subjected to 3-stage temperature-controlled drying. Using fan 2-9, filter 2-10 and heat exchanger 2-11 to provide wind with a flow rate of 25m / s and a temperature of 40°C, the crystals that have just entered the fluidized bed and move forward with vibration are subjected to the first stage of the cooling process. Drying, drying time...
Embodiment 2
[0022] After centrifugal separation, the obtained sodium gluconate crystal is 2000kg, the moisture content is 3.0%, the air flow feeder is used, and the fan 2-1, the filter 2-2 and the heat exchanger 2-3 are used to provide a flow rate of 50m / s and a temperature of 40°C. The wet crystals after centrifugal separation are sent to the down-rotating cyclone separator 2-4 by the hopper of the airflow conveying feeder. After the materials are suspended in the separator, the crystals enter the vibrating fluidized bed from the outlet at the lower end of the separator. 2-8.
[0023]After the wet crystal material of sodium gluconate enters the fluidized bed, it is subjected to 3-stage temperature-controlled drying. Using fan 2-9, filter 2-10 and heat exchanger 2-11 to provide wind with a flow rate of 30m / s and a temperature of 45°C, the crystals that have just entered the fluidized bed and move forward with vibration are subjected to the first stage of the cooling process. Drying, dryi...
Embodiment 3
[0025] in accordance with figure 2 Schematic diagram of the vibrating fluidized bed drying process device for the wet crystals of sodium gluconate.
[0026] After centrifugal separation, the obtained sodium gluconate crystal is 2000kg, and the moisture content is 3.2%.
[0027] The centrifugally separated sodium gluconate wet crystals fall into the hopper 2-4 of the air flow feeder under the action of gravity, and then use the fan 2-1, the filter 2-2 and the heat exchanger 2-3 to provide a flow rate of 60m / s The wet crystals discharged from the hopper are sent to the down-rotating cyclone separator 2-5 through the conveying pipeline with the wind at a temperature of 35 °C.
[0028] After the sodium gluconate wet crystal material enters the fluidized bed, three stages of temperature-controlled drying are carried out. The first stage of drying is performed by the wind on the crystals that have just entered the fluidized bed and move forward with the vibration. The drying time...
