Drying device of L-ascorbate-2-phosphate

Abstract

The invention relates to the technical field of drying devices, and discloses a drying device of L-ascorbate-2-phosphate. The drying device comprises a drier. A first grading plate is installed in thedrier. A flow guide pipe located above the first grading plate is installed in the drier. A first flow stop pipe is installed in the flow guide pipe. By means of a drying method and device of L-ascorbate-2-phosphate, by using the first flow stop pipe and a first buffering area in cooperation, L-ascorbate-2-phosphate powder rising at a high speed is instantly buffered and enters a second flow stoppipe and a second buffering area through the first flow stop pipe and the first buffering area, the rising speed of the L-ascorbate-2-phosphate powder is reduced, on one hand, the problem that poweris attached to a pipe wall is solved, and on the other hand, the problem that the powder is driven by force to impact on the pipe wall is solved, the finally-discharged L-ascorbate-2-phosphate powderis discharged out of the drier at a constant speed, and the powder discharging speed is kept stable.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a drying method and device for vitamin C phosphate. Background technique [0002] Vitamin C is produced through efficient catalyzed phosphorylation. It is an ideal vitamin C additive in the feed industry and is suitable for aquaculture and animal husbandry. [0003] The working principle of the existing drying device for vitamin C phosphate is as follows: Figure 5 As shown, the hot air enters the bottom of the dryer tangentially and forms a strong rotating wind field driven by the agitator. The pasty material enters the dryer from the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force, and the block material is quickly crushed, fully contacted with hot air, heated ,dry. The dry material after dehydration rises with the hot air flow and is recovered by the cyc...

AI Technical Summary

Problems solved by technology

The dehydrated dry material rises with the hot air flow, and is recovered by the cyclone separator and dust collector. The wet or bulky material is thrown to the wall of the device by centrifugal force, and falls to the bottom again to be crushed and dried. As vitamin C phosphate is processed Afterwards, it is off-white powder, and vitamin C phosphate is affected by the hot wind, causing the vitamin C phosphate to rise faster, and the vitamin C phosphate is impacted by the wind to form a strong impact on the inner wall of the dryer and the discharge pipe. , resulting in a part of the vitamin C phosphate ester powder adhering to the inner wall of the dryer and the discharge pipe. In addition, the dryer and the discharge pipe are relatively large in size and cannot be processed quickly, resulting in the inner wall of the dryer and the discharge pipe The surface is gradually adhered by vitamin C phosphate powder, the old vitamin C phosphate powder is mixed with the new vitamin C phosphate powder, and the tube wall of the dryer and discharge pipe is gradually thickened, resulting in the inner wall of the dryer and discharge pipe The thickness is different, which increases the resistance of the powder during transmission and seriously affects the processing and production of the powder
