Embodiment 1
[0025] Prepare the device that contains iodine salt, one end of dry salt belt weighing scale 10 links to each other with constant temperature iodine solution barrel 20 through filter 30 by iodine solution metering pump 40, and the other end is communicated with the feed inlet of continuous cooling mixer 50, and described continuous The outlet of the cooling mixer 50 is sequentially connected with a sieving machine 80 and a dry salt belt conveyor 90 .
[0026] The continuous cooling mixer 50 includes an agitator 51, an air inlet chamber 52, a mixing chamber 55, a separation chamber 56 and an air outlet chamber 58 arranged in sequence from bottom to top, wherein an air distribution chamber is arranged between the air inlet chamber 52 and the mixing chamber 55. Plate 53, the stirring end of described stirrer 51 passes through air inlet chamber 52, and passes through by described air distribution plate 53, is positioned at described mixing chamber 55; The other end of the salt bel...
Embodiment 2
[0029] Take 10kg of iodine content of 5.5% (mass percentage) seaweed iodine concentrate and dilute to 40kg according to the volume ratio of 1:3, put it in the constant temperature iodine solution barrel (20) and start the stirring device to make the solution mix evenly and keep the solution temperature at 25°C, then filter the iodine-containing iodine solution through the filter (30) and then pass the iodine solution metering pump (40) for use;
[0030] Turn on the salt belt weighing scale (10), and evenly pass the salt belt weighing scale (10) through the iodine solution with a water content of 3% through the fluidized bed and dry the salt at a temperature of 85°C, according to the salt belt weighing scale (10) Set the initial value of the flow rate to zero, then start the iodine solution metering pump, the filtered seaweed iodine solution is metered by the iodine metering pump, and then sprayed on the surface of 25 tons of dry salt on the salt belt metering scale, and the iod...
Embodiment 3
[0034]Take 11.6 kg of iodine-containing 5.5% seaweed iodine concentrate and dilute it at a mass ratio of 1:3, place it in a constant temperature iodine solution barrel (20) and turn on the stirring device to mix the solution evenly, keep the solution temperature at 20°C, and then mix the solution containing The iodine iodine solution passes through the iodine solution metering pump (40) after filtering through the filter (30), and is ready for use;
[0035] Turn on the salt belt weighing scale (10), pass the iodine solution with a water content of 3.3% through the fluidized bed and dry the salt at a temperature of 80°C evenly through the salt belt weighing scale (10), according to the salt belt weighing scale (10) Set the initial value of the flow rate to zero, then start the iodine solution metering pump, the filtered seaweed iodine solution is metered by the iodine metering pump, and then sprayed on the surface of 25 tons of dry salt on the salt belt metering scale, and the i...
