Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic low-temperature extraction equipment, specifically a device for ultrasonic synergistic enzymatic low-temperature extraction of instant black tea. Background Technology

[0002] Instant black tea is a new type of solid beverage made from black tea through withering, rolling, fermentation, and drying processes. Its production process includes two technical routes: low-temperature instant and hot-soluble. The low-temperature process uses liquid nitrogen cryogenic grinding and vacuum drying to achieve cold-soluble properties at 5-10℃. The hot-soluble type uses centrifugal separation and instant sterilization technology to shorten the production cycle to within 30 minutes. The product is divided into cold-soluble and hot-soluble types and is suitable for tea beverages, baked goods, and pharmaceuticals. During the processing of instant black tea, ultrasonic extraction machines are sometimes used to extract active ingredients from the tea. An ultrasonic extraction machine is a device that uses ultrasonic technology to extract active ingredients from plants, animals, or microorganisms. Its core principle is to accelerate the dissolution of target components through the cavitation effect, mechanical vibration, and thermal effect generated by high-frequency vibration, while maintaining a low-temperature environment to protect heat-sensitive substances.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a device for low-temperature ultrasonic-enzymatic extraction of instant black tea, comprising an extraction tank 1, an ultrasonic generator 2, ultrasonic transducers 3, a suction pipe 15, a pump body 5, a condenser 6, a reflux pipe 7, and a flow guide assembly. The extraction tank 1 has an internal extraction cavity 8 with two sets of mounting brackets 9 symmetrically installed inside. An inlet pipe 10 is installed at the top of the extraction cavity 8, and a discharge pipe 11 is installed at the bottom. The ultrasonic generator 2 is installed on one side of the extraction pipe and connected to several sets of ultrasonic transducers 3 via wiring. These ultrasonic transducers 3 are evenly installed on the two sets of mounting brackets 9. The suction pipe 15 is built into the extraction cavity 8 and its upper end is connected to the pump body 5. The outlet end of the pump body 5 is connected to the condenser 6 via a pipeline. One end of the condenser 6 is connected to the return pipe 7, which is built into the extraction cavity 8. The flow guide assembly includes an arc-shaped liquid accumulation plate 12, a connecting pipe 13, a second pump body 14, a suction pipe 15, a extraction rod 16, a return pipe 17, and an arc-shaped plate 18. The arc-shaped liquid accumulation plate 12 is installed in the extraction cavity 8. The upper end of the connecting pipe 13 is connected to the arc-shaped liquid accumulation plate 12, and the lower end is connected to the discharge pipe 11. The second pump body 14 is installed on the top of the extraction tank 1, and the suction end is connected to the suction pipe 15. The suction pipe 15 is built into the extraction cavity 8. The extraction rod 16 is divided into several groups and evenly installed on the suction pipe 15. The return pipe 17 is installed at the liquid outlet end of the second pump body 14, and the lower end is connected to the arc-shaped plate 18. The arc-shaped plate 18 is located at the top of the extraction cavity 8.

[0019] Further improvements, such as Figure 1 As shown, the arc-shaped liquid accumulation plate 12 has a concave arc surface structure and a liquid accumulation cavity 19 is formed in the middle. The liquid accumulation cavity 19 is connected to the connecting pipe 13 to facilitate the centralized drainage of liquid.

[0020] Further improvements, such as Figure 1 As shown, the connecting pipe 13 is arranged vertically and is equipped with a valve 20.

The instant black tea solution flows down through the partition 22 and is discharged from the drain hole 23 to achieve the purpose of guiding the flow and improve the fluidity of the internal solution, thereby reducing the problem of decreased extraction effect due to dead corners.
