Description
СПОСОБ СУШКИ ТЕРМОЧУВСТВИТЕЛЬНЫХ МАТЕРИАЛОВMETHOD FOR DRYING HEAT-SENSITIVE MATERIALS
1one
Известны способы сушки термочувствительных материалов, например уротропина, путем их кратковременного нагрева до температуры выше допустимой и последующего охлаждени до температуры ниже температуры разрушени .Methods are known for drying heat-sensitive materials, for example, urotropine, by briefly heating them to a temperature above the allowable one and then cooling to a temperature below the destruction temperature.
С целью повышени качества сушки предложено нагрев материала осуществл ть при кондуктивном теплоподводе с одновременным его перемешиванием и размельчением до порошкообразного состо ни .In order to improve the quality of drying, it has been proposed to heat the material with a conductive heat supply while simultaneously mixing it and grinding it to a powder.
Нагрев целесообразно вести со скоростью 10-30°С/сек, а охлаждение со скоростью 15-45°С/сел;.Heating is advisable to maintain at a speed of 10-30 ° C / s, and cooling at a speed of 15-45 ° C / villages ;.
Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.
Уротропин (т. разл. 45°С) с влажностью 5% и более подают из питател в сушильную камеру, где его нагревают до 90-100°С, одновременно размельчают, перемешивают иUrotropin (t. Decomp. 45 ° C) with a humidity of 5% and more is fed from the feeder to the drying chamber, where it is heated to 90-100 ° C, simultaneously crushed, mixed and
перемещают вдоль камеры с помощью перемешивающего устройства, затем охлаждают до 25-30°С и вывод т из сушильной камеры.move along the chamber with a stirrer, then cooled to 25-30 ° C and removed from the drying chamber.
