Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the spherical or oval-shaped fruits of the Qiao tree, which grows in Yunnan Province, China, and other tropical and subtropical regions. It relates to a method for producing a powder raw material for a coffee-like beverage using the present invention.

The first feature of the present invention is that guava fruit is used.

The second feature is that powdered raw materials for coffee-like beverages can be produced in a short time using extremely simple equipment.

The third feature is that the powder raw material described above can be made at extremely low cost.

The fourth feature is that the coffee-like beverage produced using this powdered raw material is more delicious and useful for health than the so-called original coffee beverage produced from the powdered raw material of coffee nuts.

Next, the method for producing the powder raw material according to the present invention will be explained in detail.

First, collect the guava fruit.

The best time to collect is just before the fruit is fully ripe.
Or, it is done at a suitable time before ripening.

Next, the spherical or oval fruits are sliced individually or in a plurality of pieces.
The slicing may be performed one by one using a knife, or may be performed using a suitable slicing machine. The thickness of the slice is about 3 to 4 mm. Each sliced piece contains a considerable amount of water.

Then, once the slices are completed, dry them. The drying method may be carried out naturally under the sun, or may be carried out forcibly using a dryer or the like. The degree of drying is approximately half of the moisture initially contained in each slice, with the other half remaining in the slice. In the case of sunlight, about two days are sufficient to dry it to this extent.

Next, a ripening operation is performed. The method and means of aging do not matter. Usually, it is kept in a room for about two days. This aging process causes the powder contained in the slices to saccharify, creating a unique flavor that is unique to this beverage and not found in other beverages. Approximately half of the water remaining in the slices plays a useful role during ripening.

Next, the slices are removed from the chamber and dried. In this case, drying can also be done in the sun,
Although it may be done forcibly using a dryer, drying naturally under the sun is more suitable. The degree of drying is as dry as possible under the sun.

Next, the slices are dried almost completely by hot air drying. In this case, forced drying using a hot air dryer or the like is suitable for drying, rather than natural drying under the sun.

This forced drying reduces the moisture content of the slices to 4%.
~7%. This forced drying makes it possible to preserve the slices as raw materials.

Next, the process of roasting the slices described above begins. The temperature for roasting is about 200℃ to 300℃, preferably about 240℃, for about 10 minutes.
Do this for 15 minutes.

This process is useful for adding color and flavor to the slices.

Next, the slices are crushed. This pulverization is to roughen the sliced pieces to facilitate the next powder processing process, and is carried out using a suitable roughing machine.

Next, this rough raw material is powdered. A rotary cutter machine is used to make powder. This machine has a rotary cutter and rotates at approximately 2.650 revolutions per minute for approximately 2 minutes.

As a result, the rough raw material described above is processed into fine powder.

Next, this powdered raw material is placed in a centrifuge and rotated at high speed to sort out the particle size.

Next, from the powdered raw materials selected above,
Take out the raw material with the optimum particle size, place it in a suitable container and seal it.

The container for storing the product may be a metal can or a synthetic resin bag, but it is preferable that the container can be completely sealed.

To make a coffee-like beverage from the powdered raw material according to the present invention produced by the above process, it is possible to open the container, take out an appropriate amount, soak it in boiling water to dissolve the extract, and drink it, or to drink it by pouring it into a cup-shaped filter paper. It is also a good idea to pour boiling water over the top of the powder to dissolve the extract in the powder and drink it. Alternatively, you can pour boiling water over the powder and drink it as is while stirring.

In this way, the powdered beverage according to the present invention is a useful beverage that has the aroma and taste of a natural food.

As described above, the present invention is a method for producing a powdered raw material that uses guava fruit and can produce a delicious beverage with a coffee-like aroma and delicious taste in a short time using extremely simple equipment. , which has excellent practical effects.

Claims (1)

[Claims] 1. Slice the fruit of the English name guava (also known as guava in Chinese and Japanese name), which is produced in the tropics and subtropics, semi-dry the slices, put them in a room to ripen, and then After thoroughly drying these slices, they are roasted to give them color and improve their aroma.Furthermore, these slices are crushed into a coarse powder, then processed into a fine powder, and finally, this A method for producing a powdered raw material for a coffee-like beverage, characterized in that the powder is sorted by centrifugation and then, if necessary, stored in a suitable container and sealed.
