Description

TECHNICAL FIELD

[0002] Tea, commonly known as tea, generally includes leaves and buds of tea plants;

[0003] The tea production steps include tea fixation, which refers to destroying the activity of oxidase in fresh leaves through high temperature to inhibit the oxidation of polyphenols and at the same time to release the grassy flavor, and is a key step for forming the quality of tea;

[0004] In the traditional tea processing field, there are various types of fixation devices, including common ones such as drum fixation machines and microwave fixation machines. These fixation devices play a crucial role in the tea processing process. They perform fixation treatment on tea through specific working principles and operation methods, so that the tea maintains the desired quality and flavor. After completing the fixation process, the tea needs to be cooled quickly because if the fixed tea is not cooled in time, it will face the risk of excessive oxidation, which not only affects the taste of the tea and makes it lose its original fresh and refreshing flavor, but also causes a large amount of aroma to be lost, thereby seriously affecting the quality of the tea.

[0005] In actual operation, the cooling method for fixed tea usually adopts two common methods: spreading and airing or fan blowing cooling. However, the fixation and cooling processes are usually independent of each other.

DETAILED DESCRIPTION

[0051] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail in an exemplary manner combined with the drawings of the specification. Example one

[0052] Please refer to Figures 1 to 8 The present application provides a technical solution: integrated tea fixation cooling integrated equipment, comprising:

[0053] Fixation cooling box 1, the inside of the fixation cooling box 1 is provided with a heat insulation plate 20, the fixation cooling box 1 is divided into fixation chamber 21 and cooling chamber 22 through the heat insulation plate 20, the fixation chamber 21 is located above the cooling chamber 22;

[0054] Drum 19, rotatingly arranged in the inside of the fixation chamber 21, and the inside side wall of the fixation chamber 21 is installed with a hot air plate 27 at the position corresponding to the drum 19;

[0055] An evaporator 23 is arranged at the inner bottom end of the cooling chamber 22, and a condenser 12 is arranged on the outer wall of the fixation and cooling box 1 corresponding to the position of the evaporator 23;

[0056] A heat collecting assembly is arranged for collecting heat inside the fixation chamber 21, and the heat collecting assembly comprises a second heat exchanger 37 arranged above the fixation chamber 21, and a conveying assembly is arranged above the second heat exchanger 37 and communicates with the roller 19;

[0057] The tea leaves inside the fixation chamber 21 are subjected to high-temperature fixation treatment by the hot air plate 27, and after the fixation treatment, the tea leaves to be cooled are conveyed into the cooling chamber 22, and the fixation tea leaves are subjected to cooling treatment by the evaporator 23, and the condenser 12 is arranged to cooperate with the evaporator 23 to continuously perform cooling treatment on the inside of the cooling chamber 22;

[0058] When the hot air plate 27 performs high-temperature fixation on the inside of the fixation chamber 21, the heat collecting assembly can collect the high temperature brought out by the fixation waste gas inside the fixation chamber 21 and preheat the tea leaves on the conveying assembly, thereby shortening the heating time of the tea leaves. Embodiment Two
