Embodiment Construction

[0034] The technical solution of the present invention will be further specifically described below in conjunction with the accompanying drawings.

[0035] see figure 1 As shown, the existing vertical continuous crystallizer, its multi-stage coil vibrating continuous cooling crystallizer structure includes a shell 1, a flat cover 2, a material distribution device 3, a scraping device 4, a conical head 5, a cooling plate Tube 6; its shell 1 is a vertical cylindrical container, and multiple sets of cooling coils 6 are arranged in the shell 1, and multiple sets of cooling coils 6 are respectively connected with cooling medium distribution pipes 10, forming multiple sets from top to bottom The single crystallizers connected in sequence are equivalent to multiple coil heat exchangers, which remove the heat of crystallization and other mixing heat to complete the cooling and crystallization of materials. The multi-group cooling coils 6 are composed of multi-layer polygons wound by ...

Abstract

The present invention relates to process of producing crystalline fructose in a vertical continuous crystallizer, and is based on the continuous crystallizer in the invention of disclosing number of CN 2774609. The fructose cooling crystallization process requires cooling crystallization capacity over 5 sq m / cu m, reasonable connection of the cooling assemblies and strictly controlled temperature. The production process of crystalline fructose has stable temperature gradient of material system, ideal temperature lowering effect, sustained crystal seed supply and sustained and stable production.

Description

technical field [0001] The invention relates to the field of preparation of organic compounds, in particular to the production process of crystalline fructose on a vertical continuous crystallizer. Background technique [0002] In the prior art, the patent number applied by Xi'an Aerospace Huawei Pressure Vessel Equipment Manufacturing Co., Ltd. on April 27, 2005 is: 200520078682.4, the name is: multi-stage coil vibration continuous cooling crystallizer, and the publication number is: patent CN2774609 The literature discloses a multi-stage coil vibrating continuous cooling crystallizer, in which the internal cooling components realize the linear motion of the overall up and down vibration, cooling without dead zone, and the crystallization of the materials entering the equipment is uniform; The seeds are supplied by the equipment itself, and the crystallization process is continuous. In the document, it is only mentioned that the cooling units can be grouped according to th...
