Embodiment 1

[0021] Wash 100g of dried tea tree flowers with water, dry them and crush them to 20 mesh powder, put them into the subcritical extraction equipment, transport the deionized water to the preheater through the pressure pump to preheat, when it reaches 100℃, add the water In the extraction tank, the control solid-liquid ratio is 20ml / g. When the pressure of the extraction tank reaches 15Mpa, start timing, and after 30 minutes of extraction, the extract flows through the collector to the collector. Add 50 g of NaCl to the obtained extract and stir well to dissolve and break the emulsion. Then add CH to the extract in a ratio of 1:1 2 Cl 2 and fully mixed, separated after standing for 30min, and collected CH 2 Cl 2 Layer and add 40g of anhydrous sodium sulfate, filter, collect the filtrate, collect the extract after concentration, weigh and calculate the yield of tea tree flower essential oil.

[0030] Wash 100g of dried tea tree flowers with water, dry them and crush them to 20 mesh powder, put them into self-made subcritical extraction equipment, transport deionized water to the preheater for preheating through a pressure pump, and when it reaches 110°C, put Water is added in the extraction tank, and the control solid-liquid ratio is 30ml / g. When the pressure of the extraction tank reaches 10Mpa, the timing extraction is started, and after 45 minutes of extraction, the extract flows through the cooler to the collector. Add 60g of NaCl to the obtained extract and stir well to dissolve and break the emulsion. Then add CH to the extract in a ratio of 1:1 2 Cl 2 and fully mixed, separated after standing for 50min, and collected CH 2 Cl 2 Layer and add 30g of anhydrous sodium sulfate, filter, collect the filtrate, collect the extract after concentration, weigh and calculate the yield of tea tree flower essential oil.

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

[0001] technical field [0002] The invention relates to an additive for improving the quality of shredded stems, a preparation method, equipment and application, and belongs to the technical field of extraction and application of natural product active components. Background technique [0003] Camellia sinensis is a five-petal white flower between the leaves of the tea tree (scientific name: Camellia sinensis), which is slightly fragrant. Most of the existing methods for extracting tea tree flower essential oil are water distillation and solvent method. The water distillation and solvent methods have the disadvantages of high energy consumption and long cycle time, and the fragrance of essential oils will be damaged after prolonged high-temperature exposure, and the quality of the obtained essential oils is poor. Therefore, in today's energy shortage and environmental deterioration, the development of new extraction technologies with high efficiency, energy saving...
