Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, and particularly relates to a sterilization device for concentrated tea liquid. Background Art

[0002] Tea concentrate is made from finished tea through processes such as extraction, clarification, concentration, blending, sterilization, and filling. It is tea original juice or flavored tea juice. In the production and processing of tea foods, tea beverages, and new tea drinks, tea concentrate is often used as raw pulp or main agent, and it is a new deep-processed tea product. Compared with the processing process of instant tea, the tea concentrate lacks the drying step. Especially, high-temperature spray drying is likely to 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, in the sterilization step, the tea concentrate is sterilized under high temperature and high pressure. During the high-temperature and high-pressure sterilization process, the sterilization time under high temperature and high pressure is not easy to control. During long-time high-temperature and high-pressure sterilization, the flavor substances in the tea concentrate are easily damaged, and the inherent flavor substances such as aroma, color, and taste in the tea concentrate will be lost, resulting in poor taste of the tea concentrate. Summary of the Utility Model

[0004] The utility model aims to provide a sterilization device for concentrated tea liquid, which can quickly sterilize the concentrated tea liquid at high temperature and ensure the flavor substances in the concentrated tea liquid.

The outer surface of the tea concentrated liquid output pipe 6 is wrapped with a cooling structure for rapidly cooling the tea concentrated liquid. Figure 1 In this embodiment, through the heating pipe arranged on the outer surface of the material pipe, hot gas is conveyed into the heating pipe through the steam access pipeline 3, so that the temperature of the heating pipe rises rapidly. When the temperature of the heating pipe reaches the temperature required for high-temperature sterilization, tea concentrated liquid is conveyed into the material pipe. The tea concentrated liquid is subjected to high-temperature sterilization in the environment of the heating pipe, and the high-temperature sterilized tea concentrated liquid is rapidly cooled through the cooling structure. The cooled tea concentrated liquid is output outward through the tea concentrated liquid output pipe 4, thereby ensuring rapid sterilization of the tea concentrated liquid at high temperature. At the same time, the rapid cooling controls the time of high-temperature sterilization. Therefore, the flavor substances in the tea concentrated liquid can be ensured.

[0028] Among them, the cooling structure includes a cooling pipeline sleeved on the outer surface of the tea concentrated liquid output pipe 6.
