Ultra high-speed preparation method and device for tea making water

Abstract

The invention provides an ultra high-speed preparation method and a device for tea making water. The method comprises the steps of: setting flow and each-stage electric power; dividing a water body heating curve of a pipeline heater into a quickly-heated linear region and a slowly-heated nonlinear region; leading the pipeline heater to work in the controllable nonlinear region and keep away from the linear region by a master control board; heating up the water which is fed into the pipeline heater; obtaining the water with a target water temperature from a water outlet; installing an outlet water temperature sensor at the water outlet; computing, tracking and compensating the water temperature decrease caused by the characteristic drift and the air injection since the pipeline heater works for a long time by the master control board; automatically adjusting the electric power by a heating body sensor according to the heating curve when the water is heated up; and precisely controllingthe water temperature at the water outlet at + / -2 DEG C. After the tea making water is prepared by the method and the device, and the phenomena that the temperature rise is too fast, the water is highly burnt, and the water cluster is broken caused by the hysteretic response speed of the heating body sensor are thoroughly eradicated, so that the water can be used for making the tea which is mellow, fragrant, sweet and good in aroma and taste, and therefore, the device is a substitute for upgrading and updating the existing water dispenser.

Description

technical field [0001] The invention relates to a method and equipment for making water for making tea, in particular to a method and device for extremely rapid preparation of water for making tea suitable for use in homes, restaurants, teahouses, nursing homes, unit restrooms and other places. Background technique [0002] With the continuous improvement of people's living standards, more and more people are aware of the need to improve the quality of life, and tea art is a part of oriental food culture, especially in my country, which has a long history of tea culture, and has rich tea drinking experience and methods and tea sets. A group of professionals with excellent tea art also emerged at the historic moment, and continued to carry forward the tea culture. [0003] Patent application number CN201010207530.5 "Pipeline Electric Heating Extremely Fast Water Boiling Machine" provides a kind of hot water that can boil 95-99°C within 3-5 seconds, and burn as much as needed, ...

Problems solved by technology

[0003] Patent application number CN201010207530.5 "Pipeline Electric Heating Extremely Fast Water Boiling Machine" provides a kind of hot water that can boil 95-99°C within 3-5 seconds, and burn as much as needed, saving energy and time. There are still deficiencies in the water boiler, because the thermal response speed of the NTC thermistor used to feed back the temperature information for the pipeline heater is slow, and when it is greater than 1 second, it will cause information lag and difficult temperature control

The inlet water temperature of the water source also has great differences with the environmental changes in different seasons and different regions. Due to the lag of the temperature control link, the water temperature at the outlet of the ultra-high-speed water boiler is unstable, and even the phenomenon of excessive water temperature and steam injection may occur. Not only People who are prone to burns will also affect the service life of the equipment

At the same time, because of the destruction of the small water molecule groups of the over-burned water source, the oxygen content is reduced, and it is difficult to brew high-quality mellow tea with this water.

[0004] Patent application number CN201110009740.8 "A method of heating water by using a heating pipe and a tea making machine using the method" is to solve the problem that the water in the heating pipe is easy to be overheated, and the overheated vaporization splash caused by boiling will scald people and damage the equipment. , to meet the requirements of hot water at the water outlet for the tea maker, but it still sets a predetermined heating temperature for each section of the heating pipe according to the temperature of the water outlet, and the water is heated by each section of the heating pipe to make the water The temperature reaches the predetermined heating temperature, this method still does not compensate for the hysteresis of the NTC thermistor

[0005] To make a cup of good tea with complete color, fragrance and taste, it is necessary not to damage the molecular group structure of the original water body in the heating process of water, but the water boiled by the water boiler and tea maker of the above two patent applications is not suitable. Water for making tea is only suitable for general drinking water
