Problems solved by technology

[0004] The existence of microorganisms has adverse effects on the tea making process
Microorganisms exist widely, there are many types, and they reproduce rapidly, which can easily cause changes in the quality of tea. The traditional methods of sterilization are heating and drying. This method is not effective in sterilizing bacteria. It will reawaken and reproduce, and cannot fundamentally kill microorganisms

Abstract

The invention discloses a tea making technology using light microwaves. The technology comprises the following steps of: sunning with light waves; putting fresh tea leaves in light wave equipment; turning on a power supply, wherein the wavelength of the light waves is 250-800nm, the power is 400-3,000W, and the illumination time is 1-10min; removing green with light microwaves, drying and sterilizing; extracting aroma with light waves; and performing tea screening, check and vacuum packing to obtain a tea product. The light microwaves are applied to the tea processing; and due to the non-thermal effect of the light microwave electric field in the green removing and drying processes, the processing time is greatly shortened, and the tea quality is maintained. Meanwhile, the light microwaves have a sterilization function and can effectively kill microorganisms in tea. Through the tea making technology using light microwaves, the fresh leaves can be collected and processed on the site, and the processes of sunning, green removing, drying, aroma extraction and sterilization are finished in one step, thus the efficiency is high, the operation is simple and the production cost is effectively reduced. Through the invention, the prepared tea has high and stable quality.

Description

technical field [0001] The invention relates to an optical microwave processing technology, in particular to a technology for processing tea leaves by using optical microwave. Background technique [0002] The tea industry has broad prospects for development. Using the traditional heating method to heat the heat source from the outside of the tea leaves to the inside, there are problems of temperature difference between inside and outside and opposite directions of moisture and heat transfer. Microwaves are used to fix and dry the tea leaves. When the microwaves shine on the tea leaves, the polar molecules inside the tea leaves are affected by the periodic changes of the microwaves, and undergo periodic activities with the microwaves, causing the molecules inside the tea leaves to collide at high speed to generate a large amount of frictional heat. Increase the temperature of the material, so as to achieve the effect of rapid heating. Microwaves are internal heating, and p...
