Description

Technical Field

[0001] This utility model belongs to the technical field of starch processing equipment, and more specifically, it relates to a modified starch separation device. Background Technology

[0002] Currently, after being processed by certain methods, the original physical or chemical properties of starch are altered to varying degrees. Based on the inherent properties of natural starch, in order to improve starch performance and expand its application range, physical, chemical, or enzymatic methods are used to introduce new functional groups into starch molecules or change the size of starch molecules and the properties of starch granules, thereby changing the natural properties of starch and making it more suitable for certain application requirements. This kind of starch that has undergone secondary processing and whose properties have been changed is collectively referred to as modified starch.

[0003] Chinese Patent Publication No. CN220258701U discloses a modified starch separation device, including a separation chamber. A feed inlet is fixedly connected to the top of the separation chamber. A first sliding frame is slidably connected to the front surface of the separation chamber. A second sliding frame is located between the front surface of the separation chamber and the bottom of the first sliding frame, and is slidably connected to the separation chamber. Discharge plates are fixedly connected to both sides of the separation chamber and both ends of the first sliding frame. This invention utilizes the feed inlet to facilitate the pouring of modified starch into the separation chamber. A vibrating motor vibrates the separation chamber. The first and second sliding frames facilitate the fixing of the first and second screens while also allowing for easy removal and cleaning. The first and second screens separate the qualified modified starch, which is discharged from the first discharge port. The unqualified starch is separated into two sizes and discharged from different discharge plates, allowing for better and more efficient reprocessing.

[0004] While this method can screen modified starch, it suffers from several drawbacks: Firstly, the combination of vibration filtration and a filter screen easily causes clogging. Secondly, it lacks multi-stage processing of the modified starch, failing to effectively disperse the starch throughout the entire process. Thirdly, the modified starch after fine filtration easily combines with moisture in the air, becoming damp and clumpy, severely impacting the quality of subsequent fine filtration. Furthermore, it cannot perform independent fine and coarse filtration operations, resulting in some interference and mixing. Finally, it cannot dry and collect the starch. Utility Model Content

The third motor 703 and the fourth motor 9 are started to drive the second drum 11 to rotate and revolve, which quickly disperses and separates the starch filtered through fine filtration until 0.1~0.5mm of modified starch is separated. Finally, the starch is heated and dried in the heating chamber 202 to prevent it from becoming damp and clumpy, and then collected in a centralized manner.
