Example Embodiment
[0050] Example 1: Using the crystallization tank of the present invention to evaporate and crystallize monosodium glutamate
[0051] 1. Crystallization process
[0052] Crystallization tank used: no thickener is connected, the tank body is cylindrical and the top and bottom are hemispherical, the first sleeve and the second sleeve are cylinders with unsealed ends, the tank body, the first sleeve 、The second sleeve axis line coincides, the agitator is on the second sleeve axis line, the structure diagram see figure 1 with figure 2 ;
[0053] The decolorized monosodium glutamate liquid to be crystallized is preheated to about 70°C through a plate heat exchanger, enters the crystallization tank of the present invention from the first feed port, and evaporates under vacuum and a stirring speed of 80r / min Crystallization, the obtained crystals are deposited to the bottom of the crystallization tank and sent out from the first crystal discharge port, and the uncrystallized material liqui...
