The invention relates to
sialic acid extracting equipment, which comprises a main body and a material inlet, wherein a debris removing mechanism and an extracting mechanism are arranged in the main body; the debris removing mechanism comprises a dissolving unit, a scraping unit and a filtering unit; the dissolving unit comprises a motor, a debris removing box and a plurality of paddles; the filtering unit comprises a falling
pipe, a first valve, a second valve, a material inlet
pipe, a filter net and a telescopic
assembly; the extracting mechanism comprises an extracting box, a storage box anda pressurizing unit; the pressurizing unit comprises a power
assembly, a push plate, a compression
pipe, a third valve and a fourth valve. Through the debris removing mechanism, the
sialic acid extracting equipment can clear away a large amount of debris in a cubilose
raw material and prevent the debris from affecting the quality of extracted
sialic acid or blocking a pipeline in the extracting equipment; furthermore, the extracting mechanism can hydrolyze cubilose
glycoprotein in a pressurized high-temperature stewing manner to allow sialic acid combined with the cubilose
glycoprotein to beconverted into free sialic acid.
