Temperature-adjusting type substitutional tea brewing machine and working method thereof

Abstract

The invention discloses a temperature adjusting type substitutional tea brewing machine and a working method thereof, and belongs to the technical field of substitutional tea brewing equipment. The substitutional tea brewing machine comprises a control unit, a hot water unit, a temperature adjusting unit and a brewing unit; wherein the hot water unit is used for preparing hot water and comprises a hot water container; the temperature adjusting unit is used for preparing water at different temperatures and comprises a temperature adjusting container and a cold water circulating system arranged around the temperature adjusting container. The brewing unit is used for brewing tea water and comprises a brewing container, and a net-shaped tea bowl used for containing substitute tea to be brewed is arranged in the brewing container. The control unit comprises a main control system which comprises a flow control module and a temperature control module. The flow control module guarantees water supply; and the temperature control module is used for ensuring that the temperature of water entering the brewing container meets the brewing temperature of the substitute tea. The brewing temperature, the brewing time, the liquid-to-solid ratio and other parameters can be accurately adjusted, the brewing quality of the substitute tea can be improved, and the device has the advantages of being automatic, intelligent, safe, convenient to use and the like and is suitable for brewing and drinking of the substitute tea.

Description

technical field [0001] The invention belongs to the technical field of substitute tea brewing equipment, and relates to a temperature-adjusting substitute tea brewing machine and a working method thereof. Background technique [0002] Substitute tea (herbal tea) refers to the roots, stems, leaves, buds, flowers, seeds and (or) fruits of plants other than the Theaceae (Theaceae) Camellia (Camellia) sinensis) for drinking. Substitute tea is different from tea in the traditional sense, the latter comes from plants of the genus Camellia in the family Theaceae, while the former comes from plants other than the genus Camellia in the family Theaceae. There are many kinds of substitute teas, common substitute teas include chrysanthemum, rose, buckwheat tea, honeysuckle, Jiaogulan and so on. In addition, Yaowang tea, Taibai tea, wolfberry leaf tea, forsythia leaf tea, vine tea, etc. are also substitute teas. In recent years, people have paid more and more attention to dietary heal...

AI Technical Summary

Problems solved by technology

[0005] Generally speaking, the vast majority of existing technologies involve brewing devices for tea leaves (Camellia genus Camellia), and there are few reports on special equipment for brewing substitute teas (Camellia genus non-Camellia family)

In addition, the prior art often has the following limitations or deficiencies: 1) The precise control of parameters such as brewing temperature, brewing time, and liquid-material ratio is ignored, which is not conducive to exerting the nutritional and health effects of substitute teas, and is also not conducive to Maintain the unique taste and flavor of substitute tea

2) Some existing technologies can only provide boiling water and cannot adjust the water temperature, which may destroy heat-sensitive nutrients and active substances, increase the dissolution of harmful components such as heavy metals, and affect the taste and flavor of drinks

3) In some existing technologies, the raw water is heated to a specific temperature (non-boiling temperature) by ordinary heaters, electric heating plates or instant heat pipes, and then the heating is stopped, and then the obtained unboiled water is directly used as brewing water. The control method will make consumers drink unboiled water, making it difficult to meet safety and hygiene standards

4) Some existing technologies only have a heating device but no cooling device, and some existing technologies use natural cooling to reduce the water temperature. The temperature adjustment process takes a long time and has low efficiency

5) The prior art that has only has a water storage container (for storing raw water) and a brewing container (for brewing tea, etc.), and the heating device (ie heat pipe) is installed on the connection between the water storage container and the brewing container On the pipeline, the efficiency of preparing warm water at a suitable temperature is restricted by factors such as the power of the heat pipe, the diameter of the pipe, and the flow rate and flow rate of the water, and the efficiency is low.

6) Many existing technologies do not have stirring devices, which is not conducive to the precise regulation of mass transfer and heat transfer processes

7) Many existing technologies do not have a disinfection system, and boiling water cannot be used to sterilize the inner wall of the container and the pipeline, nor can the substitute tea be rinsed with boiling water, and impurities such as dust that may adhere to the surface of the substitute tea cannot be washed away
