Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a concentrated tea liquid mixing device. Background Art

[0002] Tea concentrate is tea juice or flavored tea juice made from finished tea through extraction, clarification, concentration, blending, sterilization and filling. In the production and processing of tea food, tea beverages and new tea drinks, tea concentrate is often used as raw material or main agent, and is a new deep-processed tea product. Compared with the processing steps of instant tea, tea concentrate lacks the drying step, especially high-temperature spray drying, which can easily change the heat-sensitive aroma components in the tea juice. Therefore, the flavor quality of tea concentrate is often better than that of instant tea.

[0003] However, during the preparation process, the tea concentrate is stirred and mixed with other substances (such as citric acid, vitamin C, etc.). During the stirring and mixing process, due to factors such as insufficient stirring force, the tea concentrate and other substances cannot be stirred and mixed evenly, which will eventually affect the flavor and taste of the tea concentrate. Utility Model Content

[0004] The utility model aims to provide a concentrated tea liquid mixing device, which can select different mixing methods according to the substances mixed with the tea concentrate to meet the needs of different stirring strengths, so that the tea concentrate and other substances are evenly stirred and mixed, ensuring the flavor and taste of the tea concentrate.

[0008] The rotary blending structure is configured to stir and blend the tea concentrate and has multiple paths for cleaning the delivery path.

[0009] The utility model adopts two mixing structures to meet different stirring force requirements. The high-shear mixing structure is used to stir the relatively viscous tea concentrate with high-speed shear force, so that the relatively viscous tea concentrate and other substances can be evenly stirred and mixed with each other under the action of high-speed shear force, thereby ensuring the flavor and taste of the tea concentrate; when the tea concentrate is not viscous, the tea concentrate is transported to the rotating stirring structure, and the tea concentrate and other substances can be evenly stirred and mixed with normal stirring force. Therefore, it can ensure that different stirring forces can be selected for tea concentrate in different states and fully and evenly stirred and mixed with other substances, and different stirring forces can be selected according to the tea concentrate in different states, thereby saving electric energy.

[0010] In addition, the high-speed mixing structure and the rotary mixing structure in the utility model will clean the conveying path before and after mixing. However, the methods of cleaning the conveying path in the high-speed mixing structure and the rotary mixing structure are different. The conveying path in the high-speed mixing structure is cleaned at different positions, while the rotary mixing structure cleans the conveying path through multiple paths. Therefore, with this design, regardless of whether the high-speed mixing structure or the rotary mixing structure is used, the sterile state during the mixing process can be guaranteed and the quality of the tea concentrate can be guaranteed.
