Energy-saving preheating vacuum tea extraction device

Abstract

This invention proposes an energy-saving preheating vacuum tea extraction device, comprising a controller, a brewing container, a heating tank, a preheating tank, a fluid transfer module, and an air extraction unit. The controller determines the target temperature and brewing time based on the type of tea. The heating tank heats the water to the target temperature according to the control, while the preheating tank improves heating efficiency by controlling the preheating process. The fluid transfer module connects the preheating tank, the heating tank, and the brewing container, and is configured to first transport water from the preheating tank to the heating tank, and then, after heating, transport the hot water from the heating tank to the brewing container. The air extraction module draws hot air from the top of the brewing container through an air extraction pipe and introduces it to the bottom of the preheating tank, allowing the hot air to exchange heat through the pipe wall to raise the temperature of the water in the preheating tank. The air extraction pipe has a detachable connection to the brewing container for easy removal and use.
