Abstract

The invention relates to a continuous crystallizer mainly used for concentrative crystallization in monosidum glutamate production of food industry, which comprises a crystallizer (3), a raw liquid and mother liquid mixing tank (1), a feeding pump (2), a plate type heater (14), an outer circulating pump (11), a heater (5), an inner circulating pump (4) and a discharging pump (10), wherein the raw liquid and mother liquid mixing tank (1) is connected with the feeding pump (2) connected with the plate type heater (14) which is communicated with the outer circulating pump (11), the outer circulating pump (11) is connected with the heater (5) communicated with a circulated flow returning port (3.2) of the crystallizer (3), and an circulated discharging port (3.18) of the crystallizer (3) is communicated with the outer circulating pump (11); the inner circulating pump (4) is arranged at the bottom of the crystallizer (3); and an outlet of the discharging pump (10) is respectively connected with a crystal paste circulating port (3.11) of the crystallizer (3) and a crystallization-assistant slot (8). The continuous crystallizer has the characteristics of low steam consumption, high equipment yield, high degree of the automation and the like.

Description

(1) Background technology [0001] The invention relates to a continuous crystallizer device. It is mainly used for concentrated crystallization in the production of monosodium glutamate in the food industry. It can also be used for concentrated crystallization in other industries. (2) Background technology [0002] At present, the monosodium glutamate crystallization process basically adopts the interstitial single-effect concentration crystallization process. There is no major breakthrough in terms of equipment capacity and continuous production. The main disadvantages of the traditional interstitial crystallization process are: [0003] 1. The comprehensive utilization of steam is poor, and the steam consumption quota is high. [0004] According to relevant reports, the average steam consumption quota for monosodium glutamate production is 4 tons per ton of monosodium glutamate. [0005] 2. The crystallizer is small in size and the equipment capacity is low. [0006] ...
