(Background, structure, and effects of the invention) In order to achieve the above object, tea (Camellia 5i
The first step toward the completion of the present invention was to try to apply the method for producing sencha tea established for A. -nensis (L,) O, Kuntze) to the method for producing Ashitaba tea. However, this attempt ended in failure, and the Ashitaba tea obtained by this method had an inferior taste, insufficient "curvature", poor color luster, light blue color, and insufficient aroma. It was not something that could be shipped as a product.

In the process of achieving this success, several inventions were made, and the present invention is one of them. In the present invention, compared to ordinary tea, the moisture in the leaves of Ashitaba is about 2 times that of tea.
By focusing on the fact that the water content in the stem is about five times that of tea, we have developed an optimal process for removing the large amount of water contained in Ashitaba, and a method that is different from the regular tea ceremony. This was completed as a result of intensive research, recognizing that the key point in producing high-quality Ashitaba tea is to remove a large amount of it.

That is, the present invention adds a pressing step to one of the Ashitaba tea manufacturing processes, which is not present in general green tea manufacturing methods (including not only Sencha manufacturing methods but also other green tea manufacturing methods), and also adds this pressing step to one of the Ashitaba tea manufacturing processes. It is characterized in that the process is arranged between the steaming/cooling process and the rough rolling process.

As a result, enzyme activity is lost during the steaming and cooling process, and a large amount of water can be removed from the softened steamed leaves of Ashitaba. The water removed in this squeezing process includes a bright green extract with high nutritional value and yellow juice (isoquercitrun), which is the source of stickiness. There is a side effect that it can be done.

As described above, in the pressing process, a large amount of water is removed, and an appropriate amount of yellow juice, which becomes sticky, is also removed, so the next coarse rolling process can be carried out effectively, and the subsequent rolling process, A medium twisting process and a fine twisting process can also be effectively performed. In these steps, the ``twist'' and ``tightness'' are sufficiently effectively achieved, and the shape is also adjusted. The main reason for the good color, light blue color, aroma, and taste of the Asitaba leaves obtained as a product can be found in the removal of water by the above-mentioned pressing.

In producing Asitaba tea, it is of course possible to use only the leaves of Asitaba as a raw material, but also the stems can be used as raw materials. In the latter case, the stem part can be crushed in the pressing process, and together with the removal of a large amount of water, the work in the rough crushing process and subsequent processes can be made smooth, and the effect is becomes even more prominent.

The drawings show the manufacturing process as a block diagram. 1st
In the original leaf cutting step 1, since the leaves of Ashitaba are 6 to 8 times larger than ordinary tea leaves, they are cut to the same size as ordinary leaves. Although the stems of Angelica japonica are also used as a raw material, it is of course possible to use only the leaves as a raw material.

In the third steaming/cooling step 3, a belt-type steamer equipped with a rapid cooling machine is used. The belt-type steamer is superior to other steamers (e.g., the net barrel rotating stirring type steamer) in setting the steaming time accurately and preventing damage to the raw leaves.The steaming time for a typical tea ceremony is about 60 seconds. is the standard, but when producing Ashitaba tea, it is preferable to take a longer steaming time. 50 seconds to 30
As a result of experiments, it was confirmed that 0 seconds is appropriate, and particularly 100 seconds to 150 seconds is optimal. In addition, a pressureless steamer was used, and the steamer was configured so that it hit both the upper and lower sides of the raw leaves on the feeding belt. Through the above steaming process, the frozen vegetables become soft and the vitality of enzymes is lost.

The next fourth step, pressing step 4, is a unique step of the present invention that has not been used at all in conventional tea manufacturing methods. In this pressing step 4, it is preferable to remove moisture from the steamed leaves using a pressure roll type pressing machine that can be operated continuously. That is, the steamed leaves supplied from the rapid cooling machine can be moved onto an endless feeding belt, and the water can be removed by passing this between pressure rolls placed above and below. In addition to this, it is also possible to employ a press dewatering device or the like as the pressing step 4. The moisture removal rate in this pressing step 4 is around 20 to 60% when the frozen vegetables are made of leaves and stems of Ashitaba.
5 to 30% even if the frozen vegetables consist only of the leaves of Ashitaba
It will be around %. The functions and effects of this squeezing step 4 have already been described, so their description will be omitted.

In the fifth rough rolling step 5, the steamed leaves after pressing are uniformly exposed to hot air while applying appropriate pressure and friction, softening the leaves and stem tissues, evaporating moisture, and further eliminating ``wrinkle'' and ``shrinking''. This process uses a leaf crusher.As mentioned above, Ashitaba has a high moisture content, and even after pressing, it contains more moisture than ordinary leaves, so the amount of hot air is lower than that of ordinary tea leaves. Since the fibers of Ashitaba are strong and hard, the crushing pressure is about 1.2 to 1 times that of regular tea making.
.. The roughening effect was increased by 5 times.

The sixth rolling and twisting step 6 is a step in which the portions that could not be thoroughly rubbed by the rough rolling machine are softened by vigorously rolling, and the water content is made uniform during this process, and a rolling machine is used. As mentioned above, the fibers of Ashitaba are strong and hard, so it was preferable to apply pressure to the kneading tub or kneading pot to 1.2 to 1.5 times that in the case of ordinary tea manufacturing.

The seventh medium twisting step 7 is a step in which the twisted leaves obtained in the twisting step 6 are lightly kneaded while being exposed to hot air to remove moisture on average and create a "tightness" convenient for shaping. Use a twisting machine. This process was almost the same as that used for general tea manufacturing.

The eighth fine rolling process 8 is a process in which the tea is finished into a straight shape similar to that of Sencha, and the shape is tightened by applying pressure and heating, using a fine rolling machine. In this fine rolling machine as well, the pressurizing force is 1.2 to 1.5 times that of ordinary tea making, so that Ashitaba tea that is less likely to curl back can be obtained.
