A starch refining device with clarification and washing system and its production process

Abstract

The invention discloses a starch refining system with a clarifying and washing system and a production process of the starch refining system. The starch refining system comprises a pre-thickener, a separation machine, the clarifying and washing system, a thickener, a twelve-level starch rotational flowing device and a fiber washing device, the clarifying and washing system replaces a clarifying machine in the original corn starch process, the clarifying and washing system comprises three levels of clarifying rotational flowing devices, a first-level overflow of the twelve-level starch rotational flowing device directly enters a feed opening of a third-level clarifying rotational flowing device of the clarifying and washing system, a third-level underflow is concentrated and then enters the separation machine, a third-level overflow enters a feed opening of a second-level clarifying rotational flowing device, a second-level underflow is concentrated and then enters an inlet of the third-level clarifying rotational flowing device, a second-level overflow enters a feed opening of a first-level clarifying rotational flowing device, a first-level concentrated underflow enters the feed opening of the second-level clarifying rotational flowing device, the first-level overflow process water is used in the procedures of washing and clarifying in the automated starch production line, the quality is improved, and the system is energy-saving and environmentally friendly, and has good economic benefits.

Description

Technical field [0001] The invention relates to a starch refining device, in particular to a starch refining device with a clarification washing system and its production process. Background technique [0002] The starch washing system is an advanced solid-liquid separation technology at home and abroad. It can design and combine the different properties of corn, wheat, sweet potato, cassava, potato, kudzu and other materials with specific cyclone tube design and combination methods, and can independently complete the separation of materials , Washing, clarification, concentration and screening unit operation tasks. The high-pressure slurry pumped by the starch pump enters the middle cavity of the cylinder through the liquid inlet. When the pressure reaches 0.4-0.7Mpa, the starch slurry enters the inlet of the cyclone pipe and enters the cyclone along the tangent direction of the cyclone pipe. Inside the tube, each component of the material in the cyclone tube rotates in a spira...

Problems solved by technology

[0003] The present invention proposes a starch refining device with a clarification and washing system and its production process, which solves the problems of high overall cost and large power consumption of the current starch washing system, and uses a clarification and washing system to replace the clarification in the original refining system. The starch slurry and the washing water pass through the washing system in a countercurrent manner. The pipelines of the cyclone station are equipped according to the process requirements, and are equipped with instruments such as pressure gauges and flow meters, which are combined with the cyclone machine. The whole unit is in the process The cyclone is integrated in one body, compact in structure, and very convenient to install. There are no moving parts in the cyclone, which is durable and can ensure continuous starch processing, thereby saving costs and energy consumption during use, and greatly improving the economic benefits of users.
