Drip coffee and tea automatic maker {AUTOMATIC MACHINE FOR DRIP COFFEE AND TEA}

The present invention relates to an automatic drip coffee and tea maker, and more particularly, to automatically prepare a drip coffee and tea to provide an optimal best drip coffee and tea which is rich in taste and aroma and without variation in taste. Relates to an automatic coffee and tea maker.

Coffee beans extracted using coffee bean powder in a coffee shop or home are generally manufactured using coffee makers.

Briefly look at the process of manufacturing coffee beans through the coffee maker. First, a filter made of paper, a metal / polymer mesh, or the like is placed in a hopper of a coffee maker, and then ground coffee powder is put into the filter. When water is poured into a tank that boils water and serves as a hopper, the boiled water is provided to the coffee beans in the filter, and the coffee beans are stored in the coffee pot under the coffee maker. The lower part of the coffee pot is provided with a heater that heats the coffee pot to keep the coffee beans accommodated in the coffee pot cool.

When using the coffee maker, coffee beans powder and water can be provided to the coffee maker to easily extract the coffee beans, and there is an advantage of keeping the coffee beans extracted by the warming function.

However, if the coffee beans are extracted and retained in large quantities, the taste and aroma of the coffee beans are rapidly lowered as time passes, and in some cases, they are burnt. Therefore, there is a disadvantage that the coffee beans are not optimally supplied in the best condition.

Meanwhile, drip coffee provided directly by baristas has become popular due to the trend of slow food and high-end coffee culture. Drip coffee refers to the coffee which aroma was made while grinding beans, and handing down hot water slowly.

Place the dripper on the server, and slowly pour hot water into the coffee beans in the dripper using the drip pot. At this time, first pour an appropriate amount of water and wait until the coffee beans swell, then pour water again to extract the coffee beans. When pouring water, the barista pours water in a circle, and each barista differs in the way and time it is poured.

The drip coffee thus prepared is superior in aroma or taste to coffee beans extracted by the coffee maker, and there is a difference in aroma or taste depending on the barista.

Such drip coffee can be produced by the general public, not baristas, but the difference in taste and aroma depending on the person who makes the coffee, there is a disadvantage that can not be produced by the general coffee maker.
