Embodiment 1

[0020] Wash 100g of dried tea tree flowers with water, dry and pulverize it to 20 mesh powder, put it into the subcritical extraction equipment, deliver the deionized water to the preheater through the pressure pump, and add the water when it reaches 100℃ In the extraction tank, control the material-liquid ratio to 20ml / g. When the pressure of the extraction tank reaches 15Mpa, start timing. After 30 minutes of extraction, the extract will flow to the collector through the cooler. Add 50g of NaCl to the obtained extract and stir well to dissolve and break the emulsion. Then add CH in the extract at a ratio of 1:1 2 Cl 2 And mix well, let stand for 30min and separate after layering, collect CH 2 Cl 2 Add 40 g of anhydrous sodium sulfate, filter, collect the filtrate, collect the extract after concentration, and calculate the yield of tea tree flower essential oil by weighing.

Embodiment 2

[0029] Wash 100g of dried tea tree flowers with water, dry and pulverize to 20 mesh powder, put it into a self-made subcritical extraction equipment, and deliver deionized water to the preheater through a pressure pump for preheating. When it reaches 110°C, the Water is added to the extraction tank, and the ratio of material to liquid is controlled at 30ml / g. When the pressure of the extraction tank reaches 10Mpa, the timing extraction is started. After 45 minutes of extraction, the extraction liquid flows to the collector through the cooler. Add 60g of NaCl to the obtained extract and stir well to dissolve and break the emulsion. Then add CH in the extract at a ratio of 1:1 2 Cl 2 And mix well, let stand for 50min, separate the liquid after layering, collect CH 2 Cl 2 Add 30 g of anhydrous sodium sulfate, filter, collect the filtrate, collect the extract after concentration, and calculate the yield of tea tree flower essential oil by weighing.

[0038] Wash 100g of dried tea tree flowers with water, dry and pulverize to 20 mesh powder, put it into a self-made subcritical extraction equipment, and deliver deionized water to the preheater through a pressure pump for preheating. When it reaches 120°C, the Water is added to the extraction tank, and the ratio of material to liquid is controlled to 40ml / g. When the pressure of the extraction tank reaches 7Mpa, timing extraction is started. After 60 minutes of extraction, the extraction liquid flows to the collector through the cooler. Add 160g of NaCl to the obtained extract and stir well to dissolve and break the emulsion. Then add CH in the extract at a ratio of 1:1 2 Cl 2 And mix well, let stand for 60min, separate the liquid after layering, collect CH 2 Cl 2 Add 120 g of anhydrous sodium sulfate, filter, collect the filtrate, collect the extract after concentration, and calculate the yield of tea tree flower essential oil by weighing.

Abstract

The invention discloses an additive for improving quality of cut stem, as well as a preparation method, device and application thereof. The method comprises the following steps of: crushing dry tea flower to 20 meshes, putting into a subcritical extraction device, adding water, controlling the material-liquid ratio to be 20-40ml / g, controlling the extraction temperature at 100-120 DEG C, controlling the extraction pressure to be 7-15Mpa, extracting, then adding NaCl into an extraction solution, fully stirring and dissolving, adding CH2Cl2 into the extraction solution according to the proportion of 1: 1, fully mixing, standing for stratification, separating liquid, collecting a CH2Cl2 layer, adding anhydrous sodium sulfate, filtering, collecting filtrate, and concentrating to prepare essential oil of the tea flower, which is used as the additive for improving the quality of the cut stem. The essential oil of the tea flower according to the invention has the advantages of high extraction rate, low energy consumption, clean process, simple process and great industrial application prospects. In addition, by adding the essential oil of the tea flower, which is obtained by the preparation method, into the cut stem, miscellaneous gas of the cut stem can be effectively covered, dry tingling of smoke gas can be reduced, smoke flavor is coordinated, and the comprehensive quality of the cut stem is obviously improved.

Description

Technical field [0001] The invention relates to an additive for improving the quality of stem shreds, a preparation method, equipment and application, and belongs to the technical field of extraction and application of natural product active ingredients. Background technique [0002] The tea tree flower is a five-petal white flower among the leaves of the tea tree (scientific name: Camellia sinensis), which is slightly fragrant. The existing methods for extracting tea tree flower essential oil are mostly water distillation and solvent methods. Water distillation and solvent methods have the disadvantages of high energy consumption and long cycle. The aroma of essential oils is damaged by prolonged high temperature contact, and the quality of the obtained essential oils is poor. Therefore, in today's energy shortage and environmental degradation, the development of new extraction technologies with high efficiency, energy saving, and environmental protection has become a ...
