Abstract

The invention relates to a continuous crystallizer mainly used for concentrative crystallization in monosidum glutamate production of food industry. The continuous crystallizer consists of an upper seal head (14), an upper cylinder (12), an upper cone (9), a middle cylinder (7), a lower cone (3) and a bottom seal head (1) which are sequentially connected from top to bottom, wherein the cylinder wall of the upper cylinder (12) is connected with a crystal paste circulating port (11) and an inoculating port (17), an inner cone (10) and an inner cylinder (8) are respectively arranged in the upper cone (9) and the middle cylinder (7), and a flow guiding cylinder (4) is arranged in the inner cone (10), the inner cylinder (8) and the lower cone (3); a circulated discharge port (18) is arranged on the cylinder wall of the middle cylinder (7), a circulated flow returning port (2) and a crystal paste outlet (20) are arranged on the cylinder wall of the lower cone (3), and the bottom end of the crystallizer is provided with an inner circulating pump (21); the top of the upper seal head (14) is provided with a catcher (15), and the side of the catcher (15) is provided with a secondary steam outlet (16). 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. 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] At pres...
