Embodiment Construction

[0014] When the present invention is concretely implemented, a kind of preparation method of cold-brewed pure tea is proposed, comprising the following specific steps:

[0015] Step 1. Clean the PET bottle. In the aseptic workshop environment, select the PET bottle, place the PET bottle on the cleaning line, clean the inside and outside of the PET bottle several times, and dry the PET bottle through a blower device;

[0016] Step 2, tea injection, the PET bottle is removed from the washing line and placed on a custom rack, and the tea is manually injected into the PET bottle;

[0017] Step 3, liquid preparation, pure tea uses pure water and puts the pure water into the storage tank, controls at a certain temperature, and waits for filling;

[0018] Step 4. Filling. Put the PET bottle on the production line, pour tea into the PET bottle through the filling line and reach the standard liquid level of each bottle, and automatically screw the cap and tighten it according to the se...

Abstract

The invention discloses a making method of cold-brewed pure tea. The making method comprises the steps of PET bottle cleaning, tea leaf injection, liquid preparation, filling and high-pressure sterilization. Compared with the prior art, the preparation method has the advantages that the problems of taste and color change and nutrition loss caused by traditional high-temperature sterilization are solved, vitamins and mineral substances in the tea beverage can be well reserved, the taste is obviously superior to that of a common high-temperature sterilized beverage, and the freshness of tea leaves is reserved to the maximum extent. In the extraction process of cold-brewed pure tea (relative to hot-water brewed tea or boiled tea), release of tannic acid and caffeine in the tea can be reduced, and meanwhile amino acid molecules with sweetness are dissolved out firstly. Therefore, the bitter taste of the tea can be weakened by cold brewing, the tea taste becomes more fragrant and sweet, and the influence on sleep is reduced.

Description

technical field [0001] The invention relates to an autoclaving method for prepackaged tea beverages and injection of bulk or light-weight granule contents, in particular to a method for making cold-brewed pure tea. Background technique [0002] Cold-brewed pure tea is a tea beverage made by brewing tea leaves in cold water, as long as the raw materials are water and tea leaves. Cold-brewed pure tea produced and sold in street tea shops cannot be sterilized, and traditional sterilization methods through thermal sterilization (including inter-pasteurization, instant pasteurization, ultra-high temperature sterilization, etc.) will change the tea soup. Its own color, fragrance and nutrients, and make the tea leaves brown. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing cold-brewed pure tea has a complicated manufacturing process and effective sterilization, which has potential safety hazards for drinking and ...
