Description

Technical Field

[0001] This utility model relates to tea processing equipment technology, and in particular to a gradient pressure scenting system for jasmine tea. Background Technology

[0002] Jasmine tea is a reprocessed tea made by scenting green tea with fresh jasmine flowers. Traditional scenting processes are typically carried out under normal pressure and specific temperature and humidity conditions, relying on the natural diffusion of aroma molecules for absorption. This process has the following significant problems: First, the natural diffusion rate is slow, resulting in a scenting cycle of up to ten hours, leading to low production efficiency; second, the aroma molecules fail to fully and deeply penetrate the tea leaves, resulting in low utilization of the fresh flower aroma, high flower consumption, and a low retention rate of the initial aroma in the finished tea.

[0003] Therefore, how to design a dedicated system that can improve the efficiency and quality of the printing process has become a technical problem that this utility model urgently needs to solve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a gradient pressure scenting system for jasmine tea. Based on the aforementioned problems, this invention provides a gradient pressure scenting system for jasmine tea that solves the technical problems of low efficiency, high flower consumption, and incomplete aroma retention in traditional scenting processes, achieving efficient, energy-saving, and high-quality scenting of jasmine tea.

[0009] In the jasmine tea gradient pressure scenting system described above, the temperature control device is a condensation device, which cools and controls the humidity of the sealed pressure reactor by circulating condensate.

[0010] The jasmine tea gradient pressure scenting system described above also includes a PLC controller, which is located outside the sealed pressure reactor and is electrically connected to the vacuum module, the high-voltage power supply, the temperature and humidity sensor, and the variable frequency motor.
