Description

Intelligent matcha tea making machine and tea making method

Technical Field

The invention belongs to the technical field of food machinery, and in particular relates to an intelligent matcha tea making machine and a tea making method.

Background Art

Matcha, also known as powdered tea, is a tea powder with a specific particle size, chemical composition and flavor made by steaming, drying and grinding fresh leaves picked from tea trees after shade covering. The unique processing technology allows matcha to preserve the nutrients and active ingredients of tea to the greatest extent, showing special sensory quality characteristics and nutritional and health value. Studies have shown that matcha is rich in nutrients and active ingredients such as protein, theanine, chlorophyll, dietary fiber, vitamins, trace elements, flavonoids, etc., while the content of caffeine and theophylline is relatively low. It has the effects of promoting metabolism, maintaining blood pressure and blood sugar stability, improving memory, and relieving tension and stress (see Kurauchi et al. Anxiolytic activities of Matcha tea powder, extracts, and fractions in mice: Contribution of dopamine D1 receptor- and serotonin 5-HT1A receptor-mediated mechanisms [J]. Journal of Functional Foods, 2019).

Matcha originated in my country during the Tang Dynasty, reached its peak in the Song Dynasty and was introduced to Japan. During the Tang and Song Dynasties, matcha was an indispensable drink in people's lives. During the Ming and Qing Dynasties, matcha gradually declined and was replaced by tea leaves (tea leaves and buds in non-powdered form). The drinking (edible) method of tea is "drinking tea", that is, drinking the tea soup after brewing tea leaves and discarding the tea residue, while matcha is "eating tea", that is, taking in all the tea and water after brewing matcha (making tea). The tea drinking method (tea brewing) that has been popular since the Ming and Qing Dynasties has corresponding advantages, but also has obvious disadvantages: 1) The tea residue produced after drinking tea needs to be processed, which is cumbersome and troublesome. This is one of the important reasons why many young people are reluctant to drink tea; 2) When tea is brewed, only 35%-70% of the nutrients and active ingredients are dissolved into the tea soup, and more than 30% of the nutrients and active ingredients are discarded with the tea residue (see the processing and application of modern matcha studied by Ye Deping et al. [J]. Sericulture and Tea Newsletter, 2018; the development overview of Japanese matcha and its relationship with Chinese medicine tea therapy studied by Xu Ruiyao et al. [J]. World Journal of Integrated Traditional and Western Medicine, 2016). It is reported that the nutritional value of 1 cup of matcha is approximately equivalent to 30 cups of green tea (see Li Wei's research on the origin of Sino-Japanese tea history and analysis of the development prospects of the matcha industry [D]. Changsha: Master's thesis of Hunan Agricultural University, 2015; Dong Huanhuan's research on British nutritionists saying that matcha is the best drink [J]. Knowledge of cardiovascular disease prevention and treatment, 2016). Unlike brewing tea, Matcha changes "drinking tea" to "eating tea", which is conducive to the efficient use of nutrients and active ingredients contained in tea, and saves the tedious steps of tea residue treatment. In recent years, people have gradually realized the nutritional value and health benefits of Matcha. Matcha products have developed rapidly in my country and have gradually become popular around the world.

Matcha tea brewing method is very special, with strict requirements on water temperature, water amount, stirring method, utensils, etc. The tea brewing process and utensils (equipment) have a significant impact on the quality of matcha brewing. Su Yi, a tea expert in the late Tang and early Song dynasties, pointed out in "Sixteen Soup Products": "Soup is the life of tea. If famous tea is abused, it will be the same as ordinary powder", and made regulations on the water used for tea brewing, brewing methods, and utensils. The tea brewing method recorded by Cai Xiang in the Song Dynasty in "Cha Lu" is: "First pour the soup of 1.7 yuan of tea to make it very even, then add more, and beat it in a circle. When the soup is four-tenths on the cup, stop." Zhu Quan in the early Ming Dynasty also recorded a similar tea brewing method in "Tea Book", and expanded the popular way of brewing tea in a matcha bowl and drinking it in the Tang and Song dynasties to brewing tea in a giant pot and then distributing it for drinking (see Ding Yishou's research on the origin and development of Chinese tea drinking methods [J]. Agricultural Archaeology, 1999).

The modern matcha tea-making method basically follows the tradition of the Tang and Song dynasties, as follows: (1) Preparation: Select matcha and matcha bowls, tea whisks, tea spoons and other tea-making tools. Bamboo is the best choice for tea whisks, and metal materials such as stainless steel should not be used; (2) Boil water and wait for the water to boil: Boil the water and then cool it to a certain temperature; (3) Warm the bowl: Use boiling water to wash the tea cup (teapot) and tea whisk; (4) Make tea: Put a certain weight of matcha into the tea cup (teapot) and add hot water; (5) Beat: Quickly stir with a tea whisk to make the matcha and water blend quickly, and beat out a dense and long-lasting "foam" before drinking. Before making tea, you can also use a small amount of water to dissolve the matcha to make a paste, and then add a large amount of water to beat it, and finally get a matcha drink; (6) Clean the tea utensils.

The sensory quality of matcha is closely related to the amount of matcha, the amount of water added, the temperature of the water, and the strength, speed, and time of the tea whisk. Common matcha tea making utensils involve water heaters, teapots (cups), tea whisks, teaspoons and other utensils. When making tea, you need to manually complete the steps of boiling water, waiting for the soup, warming the bowl, making tea, whisking, and cleaning the tea utensils. The operation process is cumbersome and time-consuming. However, modern people live and work at a fast pace and lack sufficient time to make matcha tea, which seriously limits the promotion of matcha drinking and makes it difficult to meet modern people's consumption demand for matcha as a healthy drink.

There are few matcha tea-making devices in the prior art, and the degree of intelligence is generally low. During the tea-making process, important operations such as scalding tea sets (warming bowls), controlling water temperature and water volume, weighing matcha, beating tea whisks, and cleaning tea sets are mainly performed manually, and the operation procedures are cumbersome. There are many devices related to brewing tea leaves (tea leaves and buds in non-powdered form) in the prior art, but they generally lack related devices or accessories such as matcha weighing and beating tea whisks, and are only suitable for brewing tea leaves (non-matcha), which does not meet the needs of matcha tea-making. According to searches, there is no intelligent matcha tea-making machine that integrates the entire process of matcha tea-making (including boiling water, waiting for soup, making tea, beating tea, cleaning tea sets, etc.) at home and abroad.

After the water in the heating cup 101 boils, the heater 4 stops heating, and the water pipe 22 pumps the boiling water from the heating cup 101 into the tea-making cup 102 through the water pump 8, scalding the tea-making cup 102, completing the "warm bowl" link, and the "warm bowl" waste water is discharged from the water outlet 10. When the intelligent matcha tea-making machine works continuously, the "warm bowl" link can be omitted by setting the function key 17. Then, open the machine cover 2, and add a certain amount of matcha to the tea-making cup 102. Cover the machine cover 2, and the weighing device 7 automatically weighs the matcha. The temperature collector 5 monitors the temperature of the water in real time. When the boiling water cools to a specific temperature, the water pipe 22 pumps hot water of suitable temperature from the heating cup 101 into the tea-making cup 102 through the water pump 8. The flow collector 9 is used to monitor the amount of water pumped from the heating cup 101 into the tea-making cup 102. The controller 3 adjusts the amount of water pumped from the heating cup 101 into the tea-making cup 102 by controlling the opening or closing of the water pump 8. After hot water of suitable temperature enters the tea-making cup 102, the driving device 601 of the tea whisk stirrer 6 beats the matcha through the tea whisk 602, so that the matcha and water are quickly blended to produce rich "foam", and finally the matcha tea-making is completed. The matcha beverage (finished product) is taken out through the water outlet 10. After all the matcha beverage in the tea-making cup 102 is taken out, the hot water in the heating cup 101 enters the tea-making cup 102 through the water guide pipe 22, so as to realize automatic cleaning of the tea-making cup 102, the tea whisk stirrer 6, etc.

The present invention has the following technical advantages:

1) Follow tradition and maintain the sensory quality of matcha.

The present invention follows the traditional matcha tea-making principle, and encompasses the ancient steps of "boiling water, waiting for the tea to boil, warming the bowl, making the tea, and whisking", and adopts a bamboo tea whisk (non-metallic stirring paddle) for whisking, integrating the tea-making processes of boiling water and temperature control (waiting for the tea to boil), scalding and washing the tea cups (warming the bowls), weighing the matcha and controlling the amount of water (making the tea), and whisking the tea whisk. The prepared matcha beverage has a bright color, rich foam, and has traditional flavor and sensory quality characteristics.

2) Intelligent tea making, scientific and efficient.

The tea-making cup is equipped with a built-in weighing device, which can automatically weigh the matcha. During the matcha-making process, boiling water, scalding the tea-making cup (warming the bowl), weighing the matcha, monitoring the water temperature, adjusting the amount of water added, whisking, dispensing tea, and cleaning the tea set are all intelligently controlled by the controller. The display screen can display the parameter settings and the matcha-making process in real time. The invention has a high degree of intelligence, greatly reduces the manual control steps and manual operation links, and is scientific and efficient.

3) Easy to operate, safe and practical.

The function keys on the machine cover are connected to the controller. When making tea, you only need to inject cold water into the heating cup and add matcha into the tea-making cup. After setting the function parameters, you can start the whole process of making tea with one button. Sealing rings are provided at the contact points between the machine cover and the machine body, the electric coupler, and the connection between the lower wall of the machine cover and the connecting shaft. Sealing rings are also provided at the connection points between the temperature collector, the water pipe and the bottom of the heating cup. A waterproof layer is provided at the connection points between the heating cup and the base, and between the tea-making cup and the storage box, which has the function of preventing water leakage (liquid leakage) and ensuring the safety of the circuit. The "warm bowl" function of the present invention can scald and disinfect the tea-making cup before making tea; the "tea set cleaning" function can automatically clean the tea-making cup and tea whisk after making tea, eliminating the tedious process of manually cleaning the tea set.

4) Stirring with a tea whisk saves time and effort.

Manual whisking is time-consuming and laborious when making matcha tea. The present invention uses a tea whisk stirrer to automatically whisk instead of manual whisking, which greatly shortens the whisking time and reduces the labor intensity of the operator. The tea whisk can be freely disassembled and replaced, and different types of tea whisks can be replaced according to the tea making requirements of different types of matcha, which helps to improve the quality of matcha making.

5) Personalized customization to meet various needs.

The present invention has multiple parameter setting functions, including "tea type" (thin tea, thick tea, custom water amount for tea making), "stirring" (low speed, medium speed, high speed, custom stirring speed), "tea making temperature" (95-50℃), "warm bowl" (yes, no) and "paste adjustment" (yes, no), etc. When making tea, you can choose the preset mode to make traditional flavor matcha, or you can make special flavor matcha according to your personal preferences to meet personalized customization needs.

The present invention realizes the intelligent process of making matcha tea, has good application prospects in the promotion and drinking of matcha products, and has certain positive significance for the development of the matcha industry.
