Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing green tea leaves from wilting during the tea manufacturing and storage process.

As a method to prevent so-called wilting, which occurs during the tea manufacturing and storage process, where freshness of fresh tea leaves decreases and symptoms of leaf damage and dryness occur, a method of ventilating moist air into the gaps between fresh tea leaves has been proposed, and some methods have been proposed. Although these methods are in practical use, the problem with these methods is that the air and the particles sprayed by the humidifier are not always sufficiently agitated, and this is especially noticeable in methods that use floor-standing air permeable ducts. Something. In addition, obtaining sufficient stirring requires a complicated method and requires time.

In view of the above, it is an object of the present invention to provide a method for preventing green tea leaves from wilting that is optimal for a floor-standing air permeable duct by arranging simple equipment.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

First, to explain the first invention, 1 is a humidification chamber, and natural air is taken in through an air vent 2 of the humidification chamber. In the process of stirring and mixing this taken-in air with fine particles of mist sprayed by a humidifier 3, such as an ultrasonic humidifier, installed in the humidification chamber 1, and detouring it to the rear of the humidification chamber 1. The diffused fine particles are vaporized, and the air is brought to a low temperature by the heat of vaporization of the diffused fine particles, thereby producing low-temperature, humid air containing appropriate humidity. This low-temperature, humid air is guided by a fan 4 placed at the lower rear of the humidifying chamber 1 and reaches the lower rear of the humidifying chamber 1. During this process, the fine particles of the atomized mist are deposited on the inner bottom of the humidifying chamber 1. A tank 6 to be placed at an appropriate location or a standing water 5 where water has dripped without being vaporized.
The supplied water 5 is sucked up by capillary action and passed through the moistened filter layer 7, and then converted into high-humidity air (humidity approximately 90-95%) through a fan 4 installed in the humidification chamber 1. The air is sent from the air outlet 8 to a permeable duct 10 having a large number of perforated holes 9, and is blown out from the permeable holes 9 of this permeable duct 10, so that this high-humidity air is applied to the tea leaf layer 11 deposited on the permeable duct 10. Transfer the leaves to allow ventilation between the tea leaves. This makes it possible to absorb the respiratory heat and collected heat of the green tea leaves while imparting appropriate moisture to them, thereby preventing the aforementioned withering.

Next, to explain the second invention in detail, the humidification chamber 1
The natural air taken in through the air vent 2 is stirred and mixed with fine mist particles sprayed by a humidifier 3, such as an ultrasonic humidifier, installed in the humidification chamber 1. The diffused fine particles are vaporized in the process of bypassing the rear surface of the diffused fine particles, and the air is made to have a low temperature by the heat of vaporization of the diffused fine particles, and low-temperature, humid air containing appropriate humidity is generated. This low-temperature, humid air is sent to the air permeable duct 10 from the air outlet 8 via the fan 4 disposed at the lower rear of the humidification chamber 1 . By the way, there is accumulated water 5 on the inner bottom surface of the air permeable duct 10 (for example, accumulated water 5 in which fine particles of the sprayed mist have dripped without being vaporized on the inner bottom surface of the humidifying chamber 1, or from a tank 6 disposed elsewhere). (the supplied water 5 has flowed down), and a filter layer 7 is provided on the inner bottom surface which absorbs and moistens this water 5 by capillary action. The low-temperature, humid air passes through this filter layer 7, and then becomes high-humidity air (humidity is about 90~90°C).
95%), is blown out from the numerous through holes 9 of the air permeable duct 10, and sent to the green tea leaf layer 11 deposited on the air permeable duct 10 to allow ventilation between the green tea leaves. The same effect can be achieved.

Continuing to explain the third aspect of the invention, the air taken into the humidifying chamber 1 is made humid air in advance in this example. That is, natural air is first taken into the humidification chamber 12, and this air is supplied to the humidification chamber 1 without vaporizing the water 5 in the humidification chamber 12 (for example, the water 5 in a tank 6 provided elsewhere or the fine particles of the sprayed mist described later).
The accumulated water (5, etc.) that drips onto the inner bottom surface of the filter is sucked up and passed through the moistened filter layer 7 to become humid air containing appropriate humidity. This humid air is led to a humidifying chamber 1, where it is stirred and mixed with fine mist particles sprayed by a humidifier 3 such as an ultrasonic humidifier, and the humid air is brought to a low temperature by the heat of vaporization of the diffused fine particles. This results in low-temperature, high-humidity air with moderate humidity of 90-95%. This high-humidity air is sent to the air-permeable duct 10 from the air outlet 8 through the fan 4 disposed at the rear lower part of the humidification chamber 1, and is blown out from the air-permeable hole 9 of this air-permeable duct 10, and the high-humidity air is passed through the fan 4. By sending air to the green tea leaf layer 11 deposited on the air duct 10 and allowing ventilation between the green tea leaves, the same effect as the first invention described above can be achieved.

As detailed above, the present invention is a method of passing humid air through a moist filter layer to generate high-humidity air and blowing it out from a floor-mounted air permeable duct, which effectively prevents the withering of green tea leaves. It can be prevented. In addition, since humid air is made into high-humidity air through a moist filter layer, the equipment and method are simple.
High humidity air can almost certainly be produced. Furthermore, by ventilating high-humidity air, evaporation of water in the green tea leaves is suppressed, and it is expected that the freshness of the tea leaves will be maintained and the weight reduced.
