At present, the above-mentioned apparatus has been made continuous. The process flow is as follows: the decolored liquid prepared in the earlier stage enters a crystallizing tank, and is evaporated and concentrated under the condition of high heat and vacuum, so that monosodium glutamate molecules form crystallized particles. Due to the continuous production process, the formation of crystallized particles is not completely consistent, with larger particles that have completed crystallization and smaller particles that have not completed crystallization. To separate the large and small particles, the crystalline particles are fed into the thickener with a proportion of liquid. The thickener is a thin and high tank body, the crystallization liquid enters from the upper end, larger crystallization particles sink, the crystallization liquid is sent into the crystallization-promoting tank through the outlet at the bottom for further crystallization and concentration, a wet product is obtained through separation by a centrifugal machine, and the wet product is dried to obtain the finished product of the monosodium glutamate. Meanwhile, the lower part of the thickener is slowly filled with decolored liquid, smaller particles which are not crystallized yet are flushed upwards, and then are sent back to the crystallizing tank for continuous crystallization through overflow.

In the separation process, when larger crystal particles discharged from the discharge port of the thickener enter the crystallization-assisting groove through the discharge pipe, the discharge pipe is easily blocked when the larger crystal amount is large, and the discharge is influenced. Therefore, the utility model discloses a separation equipment of screening monosodium glutamate crystallization.
