  You can enjoy it immediately after adding hot water to it.
Making cold tea is also easy because it dissolves well in cold water.

Tea extract production process
Blending materials
The tea leaf raw materials are poured into a storage tank after checking that they do not contain foreign matter using such things as an air shower and a powerful magnet. The temperature of storage is regulated, and heat-sensitive tea leaf raw materials are stored in refrigerated storage at 5C or less.
Extraction
The extraction facility was designed by our company to facilitate ideal extraction of the tea components. A computerized system sets the optimal extraction conditions in accordance with such things as the origin of the tea leaves and season in order to produce high quality extracts.
Separation from tea ground
Even the smallest piece of tea ground is removed from the extract (tea water); this results in clear tea water. The removed tea grounds are collected into a special tank and recycled as fertilizer.
Concentration
Extracts are concentrated in order to efficiently convert them into powders. A special method, called membrane concentration, is used to concentrate extracts.
* What is membrane concentration?
Membrane concentration is a method that removes moisture by utilizing an RO membrane, which allows only liquid to pass through, and by application of pressure. Deterioration of flavor is minimized because this process does not use heat.
Sterilization and drying
After sterilization using a plate heater, the extracts are converted into powder using the spray dry method, which instantaneously dries the extracts by spraying them into heated air. Spray drying is our core technology, and all the facilities within our plant were developed by us, from design to construction. The spray dryer is a huge facility 34 m high and has an area of 470 m2, including building components. Products converted into powder using the spray dryer are automatically packed into bags and carried onto the next process (mixing and wrapping) by a robot and an unmanned carrier device.
Mixing and wrapping
Products converted into powders are mixed to homogenize them and are automatically wrapped and sealed after passing through screening and magnetic devices to ensure that they do not contain foreign matter. The wrapped products are then carried into automatic storage after passing through another check for foreign matter. Operation of machinery, inventory management, and management of such things as loading and unloading in the automated storage warehouse are all conducted by computers.
