Abstract

Technical Field
[0001] The utility model relates to the technical field of sugar crystallization, in particular to a fructose seed crystal circulation device. Background Art
[0002] As we all know, high-purity fructose is obtained by crystallization and extraction through centrifugal solid-liquid separation. The seed crystal is a key process for crystallization yield and crystal quality. It also directly affects the product quality, fluidity, and subsequent centrifugal separation and drying processes.
[0003] Crystal seeds are an important means of controlling the crystallization process. Currently, the crystal seeds commonly used in industry are mostly made from industrial crude products through grinding and screening. This method can easily cause the crystal seeds to contain a large amount of fine crystals, resulting in uneven particle size of the crystallized product and unqualified microorganisms.
[0004] In order to overcome these traditional problems and prevent cross contamination, the industry gradually uses semi-finished crystal products as seeds. However, since the liquid after crystallization is viscous and contains crystals, general pipeline pumps cannot achieve long-distance transportation. The structure of the rotor pump is suitable for conveying viscous liquid, but during use, the liquid contains crystals, and the inner wall often wears, resulting in metal glitter on the product and substandard quality.
[0005] To this end, the utility model provides a fructose seed crystal circulation device. Utility Model Content

[0008] The feed port is connected with a feed pipe, a feed valve is arranged on the feed pipe, a cleaning pipe is connected with the feed pipe between the feed valve and the feed port, and a cleaning valve is installed on the cleaning pipe.
[0009] As a further technical solution of the utility model, the cleaning pipe is connected to the feed port through the feed pipe, and the other end of the cleaning pipe is externally connected to the steam delivery pipe.
