Embodiment Construction
[0017] Accompanying drawing is an embodiment of the present invention, in conjunction with accompanying drawing, specifically illustrate this embodiment, in the first embodiment that is used for the method for continuous monosodium glutamate crystal, its steps are:
[0018] 1. Input the monosodium glutamate stock solution with a general concentration of 26~27Be′ and a temperature of 50~55°C into the second-effect evaporation system through the pipeline and pump body, that is, first input it into the second-effect evaporator, and concentrate the monosodium glutamate stock solution to a concentration of The monosodium glutamate liquid of 30Be' is input into the second-effect crystallizer, and the temperature of the monosodium glutamate liquid with a concentration of 30Be' is lowered to 50-55°C to obtain a supersaturated solution with a concentration of 30Be'. Monosodium glutamate crystals were obtained.
[0019] In this embodiment, the model of the two-effect evaporator is WZS30...

The invention discloses a method and a device for continuously preparing monosodium glutamate crystals. The method for continuously preparing monosodium glutamate crystals comprises the following steps that a monosodium glutamate solution passes through at least two evaporation systems composed of evaporators and crystallization separators, wherein through the evaporators, the concentration of the monosodium glutamate solution reaches a certain value, and through the crystallization separators, the temperature of the monosodium glutamate solution reaches a certain value; a supersaturated monosodium glutamate solution having concentration of 33Be' and a temperature of 70 to 75 DEG C is output; and the output supersaturated monosodium glutamate solution having concentration of 33Be' and a temperature of 70 to 75 DEG C is cooled to a temperature of 50 to 55 DEG C so that monosodium glutamate crystals are precipitated. The crystallization separators also are utilized for separation of monosodium glutamate crystals, and thus continuous production of monosodium glutamate crystals is realized and production efficiency is improved.
Description
1. Technical field [0001] The invention relates to a method and a device for continuously obtaining monosodium glutamate crystals, in particular to a method and a device suitable for large-scale production of monosodium glutamate. 2. Background Technology [0002] Monosodium glutamate is widely used as a condiment. With the improvement of people's life, the output of monosodium glutamate is also greatly improved. Therefore, the method and device for producing monosodium glutamate crystals are an important daily chemical link. In the existing In the method for producing monosodium glutamate crystals, all use the single-pot crystallization process method, which has the disadvantages of large equipment investment, low yield, large floor space, and high energy consumption, especially low production efficiency. 3. Contents of the invention [0003] In order to overcome the above-mentioned technical shortcomings, the object of the present invention is to provide a method and dev...
