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] Get 10kg iodine content and be that 5.5% (mass percentage) seaweed iodine concentrated solution is diluted to 40kg by the ratio of volume ratio 1: 3, is placed in constant temperature iodine solution barrel (20) and starts stirring device, makes solution mix uniformly, keeps solution temperature at 25 DEG C, then the iodine-containing iodine solution is filtered through the filter (30) and passed through the iodine solution metering pump (40), for use;
[0030] Open the salt belt weighing scale (10), the temperature of the iodine solution with a water content of 3% is passed through the dry salt at 85° 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 iodine s...
Embodiment 3
[0034]Get 11.6kg of iodine-containing 5.5% seaweed iodine concentrate and dilute it in a ratio of 1: 3 in mass ratio, put it in a constant temperature iodine solution bucket (20) and start the stirring device, make the solution mix evenly, keep the solution temperature at 20°C, and then mix the solution containing Iodine iodine liquid passes through iodine liquid metering pump (40) after filter (30) filters, stand-by;
[0035] Open the salt belt weighing scale (10), the temperature of the iodine solution with a water content of 3.3% is passed through the salt belt weighing scale (10) evenly through the dry salt at 80°C after fluidized bed drying, 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 iodine solution meterin...
