Embodiment Construction
[0031] Existing supercritical fluid extraction devices, such as figure 1 Shown, basically continued the design of German Wood (UHDE) company, the inventor finds that this design has the following deficiencies:
[0032] 1. The extraction kettle, the core equipment of the device, adopts the technical scheme of adding a hanging basket inside the extraction kettle to shorten the loading and unloading time of materials. In order to adapt to the loading and unloading of the hanging basket, a large opening of equal diameter needs to be opened on the upper opening of the extraction kettle. Increased the cost of the extraction kettle. The height of the factory building also needs to be doubled to increase investment in infrastructure. At the same time, the bulky and bulky extraction kettle upper end cap also needs to be equipped with a complex structure and expensive cap opening mechanism. When this solution increases the capacity of the extraction kettle, it will cause a substantial...

The invention relates to a supercritical extraction kettle and an extraction system comprising the supercritical extraction kettle. The supercritical extraction kettle comprises a tank body, wherein an upper opening and a lower opening are formed in the top end and bottom end of the tank body respectively; an upper end cover and a lower end cover are connected on the upper opening and the lower opening respectively in a sealed manner; and an inlet and an outlet, which are arranged in pair, are formed in each of the upper part and the lower part of the extraction kettle. The extraction system comprises a first extraction kettle, a second extraction kettle and a third extraction kettle which are circularly communicated in sequence; and the first extraction kettle, the second extraction kettle and the third extraction kettle are communicated with an air inlet pipe, a recycling unit and a separation unit. The supercritical extraction kettle and the extraction system have the beneficial effects that a discharging device is simple in structure, low in cost and simple and convenient to operate; the large-capacity extraction kettle is simple in structure, safe and reliable, great in production capability and low in construction cost; and with the adoption of the extraction system composed of the extraction kettle and a valve group, the saturation degree of the dissolving capacity of supercritical fluid is improved and the extraction efficiency is improved.
Description
technical field [0001] The invention belongs to the field of supercritical extraction equipment, and in particular relates to a supercritical extraction kettle and an extraction system containing the extraction kettle. Background technique [0002] Natural fragrance (spicy) extracts—essential oil and oleoresin—are important raw materials for food, daily chemical, tobacco, and pharmaceutical industries in the national economy. The traditional extraction methods of natural spices are mainly steam distillation and solvent extraction. The traditional extraction method of natural spices (spicy) has changed its natural aroma and flavor due to heat and solvent residues during the extraction process. Supercritical fluid extraction technology is currently recognized internationally as the most environmentally friendly and safe natural product extraction technology. This technology has low extraction temperature and no solvent residue, and the extract maintains the pure and natural qu...
