Abstract

Данное изобретение обеспечивает систему приготовления сырого крахмала для гипсокартонных листов, включающую весовой дозатор крахмала непрерывного действия, смеситель Вентури, вакуумное устройство захвата для подачи сухого крахмала из дозатора с регулируемой скоростью в смеситель Вентури, первый водяной насос для подачи воды с регулируемой скоростью в смеситель Вентури с образованием крахмальной предварительной дисперсии от приблизительно 2 до приблизительно 10 вес.% крахмала и второй водяной насос для подачи воды затворения к крахмальной предварительной дисперсии, система снабжена соответствующими устройствами контроля системы. Данная система обеспечивает более эффективное использование крахмала, так что количество предварительно клейстеризованного крахмала по меньшей мере на 10% меньше, чем у системы, в которой крахмал не подвергают предварительному диспергированию в воде до смесителя. Система может применяться для изготовления гипсосодержащей продукции, включая гипсокартонные листы, имеющие повышенную прочность листа и пониженный вес листа.
