Embodiment 1
[0026] The preparation of embodiment 1 rose oil of the present invention
[0027] Picking of roses: From 5:00 to 9:00 in the morning, there must be no smell or foreign matter mixed in. In principle, the flowers of the same day should be processed on the same day. If they are not finished on the same day, they should be stored in a cold storage to prevent the oily components of the flowers from volatilizing at high temperatures. The storage temperature should be 2-3 ° C, and the storage time should not exceed 48 hours. Otherwise, the oil yield will be greatly reduced.
[0028] One Distillation:
[0029] Add roses to a distillation kettle (3 cubic meters), about 500 kilograms, then add hot water or 1500 kilograms of secondary distillate, and the inlet pressure is 4kg / cm 2The steam is sent to the conical heating coil in the kettle, and the temperature inside the kettle rises from 60°C to 137°C at a heating rate of 3°C / min. The steam (produced by the flower and water mixture in...
Embodiment 2
[0042] The preparation of embodiment 2 rose oil of the present invention
[0043] Picking of roses: From 5:00 to 9:00 in the morning, pick buds that have not opened, and there must be no peculiar smell or foreign matter mixed in.
[0044] One Distillation:
[0045] Add roses to a distillation kettle (3 cubic meters), about 500 kilograms, then add hot water or 2000 kilograms of secondary distillate, and the inlet pressure is 4kg / cm 2 The steam is sent to the conical heating coil in the kettle, and the temperature inside the kettle rises from 60°C to 137°C at a heating rate of 4°C / min. The secondary steam (produced by the flower and water mixture in the kettle) enters the primary condenser (6 square meters) through the connecting pipe to condense, and the liquid storage tank collects condensate I 600kg each time, with a total amount of 1200kg, and the temperature of the condensate I is controlled at At about 30°C, enter the oil-water separator for separation to obtain 0.075 kg...
