Description

Technical Field

[0001] This utility model belongs to the field of rotary evaporator technology, and in particular relates to a sealed rotary evaporator for a snow ice machine. Background Technology

[0002] A rotary evaporator, also known as a rotary distillation apparatus, is a widely used evaporation instrument in laboratories. It consists of a motor, distillation flask, heating pan, and condenser, and is primarily used for the continuous distillation of volatile solvents under reduced pressure. It is applied in fields such as chemistry, chemical engineering, and biomedicine. Rotary evaporators can be used to recover and evaporate organic solvents. It utilizes a motor to drive the distillation flask to rotate. Because the distillation apparatus is constantly rotating, boiling chips are unnecessary and bumping is avoided. Simultaneously, due to the continuous rotation, the liquid adheres to the walls of the distillation apparatus, forming a liquid film, increasing the evaporation surface area and accelerating the evaporation rate.

[0003] In the existing technology, the installation structure of the rotary evaporator of the sealed shaved ice machine is generally relatively fixed, which makes it inconvenient to disassemble and maintain it later, affecting the maintenance efficiency of the operator and making it difficult to ensure normal use later.
