[0002] Tea drinking is a traditional Chinese dietary culture. Tea has the effects of clearing the lungs, refreshing the eyes, and invigorating the mind. With the rapid development of society and economy and the continuous improvement of people's living standards, and since most Chinese people have the habit of drinking tea, people's requirements for tea and tea-related products are getting higher and higher.

[0003] Tea extraction is a crucial step in tea processing, but traditional extraction methods often suffer from high energy consumption and low efficiency. Existing extraction devices mostly employ a single extraction method, such as basket-type or closed-loop extraction. While these devices have their advantages, they also suffer from energy waste and low efficiency. Therefore, developing a tea extraction device that integrates the features of both basket-type and closed-loop extraction, and possesses energy-saving capabilities, is an important way to solve these problems.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0027] This utility model provides an energy-saving tea extraction device that combines basket-type and sealed design, comprising:

[0028] The basket-type extraction assembly 1 consists of a liftable basket 101, a drive mechanism 102, and a first heating chamber 103. The outer wall of the first heating chamber 103 is covered with a first insulation layer 104. Both the first insulation layer 104 and the second insulation layer 202 are vacuum insulation board structures with a thickness of 15-25mm and a thermal conductivity ≤0.008W / (m·K).

[0029] The sealed extraction tank 2 is connected to the basket-type extraction assembly 1 via a connecting pipe 3. The sealed extraction tank 2 is provided with a sealing flange at the top and an annular second heating layer 201 integrated on the side wall. A second heat insulation layer 202 is provided on the outside of the second heating layer 201. A graphite spiral wound gasket is provided between the sealing flange and the tank body, and the pre-tightening force of the flange bolts is 30-50 N·m.

[0030] The connecting pipe 3 has a double-layer hollow structure. The inner layer is a food-grade stainless steel pipe, and the outer layer is covered with an aluminum silicate fiber heat insulation sleeve. The ratio of the inner diameter of the pipe to the filter mesh diameter of the basket 101 is 1.2:1-1.5:1.

[0031] The waste heat recovery module 4 includes a heat exchanger 401 and a heat pipe 402. One end of the heat exchanger 401 is connected to the exhaust port 203 of the sealed extraction tank 2, and the other end is connected to the first heating chamber 103 through the heat pipe 402. The heat exchanger 401 is a plate heat exchanger with a heat recovery efficiency of ≥65%, and the heat pipe 402 extends to the water inlet of the first heating chamber 103.

[0032] The energy-saving control unit is electrically connected to the drive mechanism 102, the first heating cavity 103, and the second heating layer 201, and is used to synchronously adjust the heating power and the lifting frequency of the basket according to the temperature sensor data.

[0033] The energy-saving control unit is configured as follows:

[0034] When the water temperature in the first heating chamber 103 reaches 70-80℃, the drive mechanism 102 is activated to raise and lower the basket 101 at a frequency of 10-20 times / minute.

[0035] When the temperature inside the sealed extraction tank 2 exceeds 85°C, the second heating layer 201 is shut off and the waste heat recovery module 4 is activated.

[0036] The device is equipped with a movable energy-saving support 5 at the bottom. The support 5 includes casters 501 and hydraulic lifting legs 502, with a load-bearing capacity of ≥500kg.

[0037] The working principle of this device can be divided into the following stages:

[0038] Heating and Extraction: First, the first heating chamber 103 heats the water to 70-80℃. During this process, tea leaves are placed in the basket 101 of the basket-type extraction assembly 1, and the drive mechanism 102 moves the basket up and down to increase the contact area between the tea leaves and the water, promoting the dissolution of the effective components of the tea leaves.

[0039] Sealed Extraction: After basket extraction, the tea liquor enters the sealed extraction tank, where sealed extraction tank 2 begins to function. The temperature inside the tank is maintained at a high level, further enhancing the dissolution rate of the tea leaves and resulting in a significant extraction effect.

[0040] Waste heat recovery: When the hot gas in the sealed extraction tank 2 is discharged, the waste heat recovery module 4 starts to work. The heat exchanger 401 recovers the waste heat from the extraction process and transfers it to the first heating chamber 103 through the heat pipe 402 to provide energy for the next round of heating.

[0041] Energy-saving control: Through the energy-saving control unit, the temperature changes of the heating chamber and extraction tank are monitored in real time by temperature sensors, and the heating power, basket lifting frequency and heat recovery mode are automatically adjusted to maximize energy efficiency and reduce energy consumption.

[0042] Therefore, this utility model presents an energy-saving tea extraction device combining basket-type and closed-loop extraction methods. This combination improves the extraction efficiency of tea, allowing the effective components in the tea leaves to dissolve more completely in the water, resulting in higher quality tea juice. The waste heat recovery module recovers and utilizes waste heat, significantly reducing the equipment's energy consumption. Simultaneously, the energy-saving control unit precisely controls the temperature and basket lifting frequency, making energy use more efficient. The device has a compact design, with components effectively connected via pipes and heat exchangers, making operation simple and convenient. Furthermore, the use of a movable energy-saving support facilitates equipment transport and installation. The closed extraction tank is equipped with a sealing flange, and the pre-tightening design of the graphite-wound gasket and flange bolts ensures safer operation under high temperature and pressure, reducing the risk of leakage and malfunction.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
