Tea drink preparation method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cold tea drink preparation methods involve prolonged contact between hot tea drinks and air, leading to contamination risks, flavor deterioration, and poor hygiene due to oxidation and external contaminant exposure, as well as the use of ice blocks that can be contaminated and alter the flavor and clarity of the drink.
Innovation Solution
A method using a high temperature and high pressure brewing machine to brew powdered tea into a hot tea drink, followed by rapid cooling with a beverage cooling device, minimizing air contact and eliminating the need for ice blocks, thereby maintaining hygiene and flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the hot tea drink is cooled down by natural cooling or refrigeration for a long period, then the tea drink can be served cold, but the contact time between the hot tea drink and air increases, leading to contamination risks and flavor deterioration
Solution Approach 1:
The patent uses ice blocks (solid phase) to cool the hot tea drink through phase transition from solid to liquid, rapidly absorbing heat and cooling the tea drink without requiring prolonged exposure to air. This resolves the contradiction by achieving fast cooling while minimizing air contact time.
Solution Approach 2:
The patent introduces ice blocks as an intermediary cooling medium between the hot tea drink and the environment. The ice blocks absorb heat from the tea drink through melting, providing rapid cooling while the tea drink remains contained, thus reducing direct exposure to air contaminants.
2Temperature
If ice blocks are added to cool down the tea drink, then the cooling effect is achieved, but the ice blocks can be contaminated by outside pollutants and alter the flavor and clarity of the drink
Solution Approach 1:
The patent uses disposable sealed ice block containers that are single-use. Each container is sealed to prevent contamination during storage and handling, and is disposed of after one use, eliminating the risk of cross-contamination between different tea drinks while maintaining effective cooling.
Solution Approach 2:
The patent employs sealed containers (flexible shells) to enclose ice blocks, creating a barrier that prevents external pollutants from contacting the ice blocks and the tea drink. The sealing film maintains the integrity of the ice blocks throughout storage and service, eliminating contamination risks.
3Temperature
If ice blocks are added to cool down the tea drink, then the cooling effect is achieved, but the tea drink becomes turbid and loses its original fresh flavor and taste
Solution Approach 1:
The use of sealed, single-use ice block containers ensures that the ice blocks remain pure and do not introduce contaminants or excess meltwater that would turbidify the tea drink. The controlled melting within the sealed container prevents flavor degradation while maintaining drink clarity.
Solution Approach 2:
The sealed container acts as an intermediary that controls the interaction between ice blocks and tea drink. It allows heat transfer for cooling while preventing direct mixing that would cause turbidity and flavor loss, thus preserving the original tea drink quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method reduces contamination risks, preserves the flavor and color of the tea drink, and ensures good hygiene by shortening the contact time between the hot tea drink and air, and avoids the contamination risks associated with ice blocks, resulting in a consistently fresh and safe cold tea drink.
Implementation Method 1

AI summary
A tea drink preparation method for preparing a cold tea drink by: using high temperature and high pressure brewing machine to brew a powdered tea so as to make a hot tea drink, and then using a beverage cooling device to cool down the hot tea drink so as to obtain a cold tea drink, and then using a vessel to take the cold tea drink for service. Thus, this method shortens the contact time between the hot tea drink and the air and reduces the risk of tea drink contamination, avoiding deterioration in color and flavor due to oxidation and maintaining good tea drink hygiene.
