AI Technical Summary
Technical Problem
Traditional drying equipment suffers from uneven drying and clumping in the processing of krill powder, resulting in low drying efficiency and poor performance.
Method used
A vacuum drying device is used. By setting air ring grooves and air spray mesh on the outer wall of the drying inner cylinder, combined with suction components and heat source components, high-pressure hot gas injection and stirring under micro-vacuum conditions are achieved. Combined with spiral conveyor components, uniform heating and continuous discharge of krill powder are achieved.
Benefits of technology
It improves the drying efficiency and effect of krill powder, prevents clumping, ensures uniform heating, and enables automatic continuous discharge.

Abstract
The invention discloses a vacuum drying device for krill powder processing, and relates to the related technical field of drying processing.The vacuum drying device comprises a drying outer cylinder, supporting legs are connected to the lower sides of the two shaft ends of the drying outer cylinder, a drying inner cylinder is rotatably connected to the interior of the drying outer cylinder, and a driving motor connected to the interiors of the supporting legs is arranged outside the drying outer cylinder; a plurality of gas ring grooves are formed in the outer wall of the drying inner barrel, and a plurality of gas spraying meshes are formed between the gas ring grooves and the drying inner barrel, so that a plurality of pressurizing gas cavities formed in the inner wall of the lower end of a gas guide ring can intermittently communicate with the interior of the drying inner barrel through the gas spraying meshes under rotation of the drying inner barrel; according to the krill powder drying device, the pressurizing air cavity is arranged, hot air guided into the pressurizing air cavity is pressurized and sprayed out in the communicating and staggering process of the pressurizing air cavity and the air spraying meshes, intermittent high-pressure hot air spraying is formed on krill powder, the krill powder can be scattered and prevented from caking, heating can be more uniform through air stirring, and the drying efficiency and the drying effect are improved.
