[0047] Working principle:

[0048] In use, the inlet / outlet 1a is opened by the sealing opening and closing door assembly 2.

The PLC controller 3 controls the lifting drive assembly 7 to drive the screen plate structure 4 to move upward to the inlet / outlet 1a, and the staff places the raw materials for preparing fragrances and flavors on the screen plate structure 4. Specifically, the PLC controller 3 controls the output shaft of the motor 701 of the lifting drive assembly 7 to rotate. The rotation of the output shaft of the motor 701 can drive the lead screw 702 to rotate. The rotation of the lead screw 702 drives the threaded intermediate support plate 403 to move up and down along the guide rib 703.

[0049] The inlet and outlet 1a are closed by the sealing opening and closing door assembly 2. The PLC controller 3 controls the lifting drive assembly 7 to drive the screen plate structure 4 to move downward. Depending on the raw material, water distillation and water distillation are selected. During water distillation, the lifting drive assembly 7 drives the screen plate structure 4 to move downward to above the water surface. During water distillation, the lifting drive assembly 7 drives the screen plate structure 4 to move downward to be submerged in the water.

[0050] The water vapor produced by distillation is condensed and crystallized in the condensation chamber 6 through the condensation pipe assembly 5 and then collected; wherein, the upper sealing cover 401, the lower sieve plate 402, and the inner wall of the preparation shell 1 form a sealed evaporation chamber.

6. The apparatus for preparing fragrances and flavorings by crystallization according to claim 1, characterized in that: The inlet and outlet water pipe assembly (10) includes a water guide pipe (10a), which is U-shaped. One end of the water guide pipe (10a) extends to the bottom surface of the water storage chamber and has two or more opening slots (10e). The other end of the water guide pipe (10a) passes through the inner sleeve (8) and the bottom side wall of the preparation shell (1) in sequence and is connected to the outlet pipe (10c) and the inlet pipe (10d) respectively. A three-way solenoid valve (10b) is provided at the connection between the water guide pipe (10a), the outlet pipe (10c) and the inlet pipe (10d). The output end of the PLC controller (3) is electrically connected to the input end of the three-way solenoid valve (10b).

7. The apparatus for preparing fragrances and flavorings by crystallization according to claim 1, characterized in that: The sealed opening and closing door assembly (2) includes a sealed lifting door (201), which is hollow cylindrical in shape. The sealed lifting door (201) is sleeved on the upper side of the preparation shell (1). A lug (206) is fixedly provided on the bottom outer edge of the sealed lifting door (201). Electric telescopic rods (203) are provided on both sides of the preparation shell (1). The electric telescopic rods (203) are fixedly provided on the outer wall of the preparation shell (1) through mounting bases (207). Above, the push rod head of the electric telescopic rod (203) slides through the support ear (206) and is provided with a through hole and a stop block (204) is fixedly connected. A spring (205) is sleeved on the outside of the push rod of the electric telescopic rod (203) located between the stop block (204) and the support ear (206). A transparent observation window (202) is provided on the outer wall of the sealed lifting door (201). The output end of the PLC controller (3) is electrically connected to the input end of the electric telescopic rod (203).

8. The method of using the apparatus for preparing fragrances and flavorings by crystallization according to claim 1, characterized in that: Includes the following steps: S1: The inlet and outlet (1a) are opened by the sealing opening and closing door assembly (2). The PLC controller (3) controls the lifting drive assembly (7) to drive the screen plate structure (4) to move upward to the inlet and outlet (1a). The staff places the raw materials for preparing fragrance and flavor on the screen plate structure (4). S2: The inlet and outlet (1a) are closed by the sealing opening and closing door assembly (2). The PLC controller (3) controls the lifting drive assembly (7) to drive the sieve plate structure (4) to move downward. Depending on the raw material, water distillation and water distillation are selected. When distilling on water, the lifting drive assembly (7) drives the sieve plate structure (4) to move downward to above the water surface. When distilling in water, the lifting drive assembly (7) drives the sieve plate structure (4) to move downward and immerse it in the water. S3: The water vapor produced by distillation is condensed and crystallized in the condensation box (6) through the condensation pipe assembly (5) and then discharged and collected; S4: After completion, the lifting drive assembly (7) drives the screen plate structure (4) to rise to the inlet / outlet (1a), opens the sealing opening and closing door assembly (2), and the staff can take out the raw material residue on the screen plate structure (4) through the inlet / outlet (1a).
