The starch vacuum dehydrator uses the principle of vacuum pump adsorption to dehydrate the starch milk to about 40% moisture content for easy drying. The equipment can automatically flush the filter screen, stir to prevent sedimentation, continuously operate to increase production volume and shorten the processing cycle.
The starch vacuum dehydrator is a device mainly used for starch dehydration. Since the purified starch has a relatively high moisture content, direct drying may easily cause the starch to become moldy or deteriorate or the drying time may take a long time. If the drying process is carried out directly by a machine, excessive moisture may easily lead to starch dehydration. Starch gelatinizes, so the starch needs to be dehydrated first and then dried. In this step, a vacuum dehydrator is needed to dehydrate the starch milk to a moisture content of about 40%, which is convenient for subsequent drying of the starch.
The vacuum dehydrator is mainly suitable for dehydrating starch before drying. It adopts the principle of vacuum pump adsorption to form a pressure difference inside and outside the drum, prompting starch to be adsorbed on the filter cloth. The liquid flows through the filter cloth along the vacuum pipe to the soda-water separation tank, and passes through Continuous vacuuming removes excess moisture from the starch adsorbed on the drum to form a filter cake, which is then scraped off by a fixed scraper and the filtrate enters the soda-water separator to achieve the purpose of separating starch, water and gas. The moisture content of dehydrated starch is less than 40% and can be dried directly.
The dehydrated starch material is in the form of loose powder. The moisture content of the dehydrated starch is about 40%, which is convenient for subsequent drying. Compared with the traditional drying method, the processing cycle is greatly shortened.
The vacuum dehydrator has a built-in spray water system, which is automatically controllable and flushes intermittently to ensure that the filter is not blocked. At the same time, the filter tank is equipped with an automatic reciprocating agitator to prevent starch deposition.
Automated dehydration processing can carry out continuous operation, automatic unloading, stable and efficient, increase starch production volume, and comprehensively improve processing efficiency.
