c. Utility Model Application Published 1982-68921 (Tea leaf, etc. supply device) This invention is equipped with an opening/closing lid that guides raw tea to the supply section, and this opening/closing lid has a heat generation function.
This lid evaporates the steam adhering to the opening/closing lid, prevents the raw tea from adhering, and allows the raw tea to be drawn out smoothly.

[Problem to be solved by the invention] However, when using instant tea as the raw material tea, it is convenient because the tea dispensing device does not have a mechanism for discharging tea leaves, but the conventional tea dispensing device can be used as is. It is not possible. The reason for this is that instant tea, which is sold commercially sealed in aluminum foil packs, has extremely high hygroscopicity, and when instant tea is opened and left to stand, it becomes wet and turns into mud. This is because, in addition to the heating means of the delivery mechanism, a dehumidification means is required in the container containing the raw tea.

The present invention was devised in view of the above-mentioned problems, and its purpose is to provide a tea serving device in which a container for storing raw tea and a raw material dropping cylinder are heated by a single heater plate. Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the above object, the tea serving device of the present invention includes a storage container 1 for powdered raw tea (instant tea), a water boiling tank 2, and the storage container 1. means 3 for sending out a fixed amount of the raw tea stored in the tank, and means 4 for sending out a fixed amount of hot water from the water boiling tank 2.
and a mixing chamber 5 having a funnel 5a for mixing a fixed amount of raw tea and hot water sent out by the two means 3 and 4, and a steam exhaust means 6 attached to the mixing chamber 5. A part 7c of the horizontally elongated electric heater plate 7 is closely attached to the raw material dropping tube 3a of the means 3 for sending out a fixed amount of the raw tea contained in the storage container 1, so that the raw material dropping tube 3a is heated and the raw material dropping tube 3a is heated. The other portion 7d of the electric heater 7 heats the storage container 1 through the device of the means 3 for sending out a fixed amount of the raw material tea.

[Function] By attaching a part of the horizontally long electric heater plate 7 in close contact with the raw material dropping tube 3a of the means 3 for sending out a fixed amount of raw material tea, the raw material dropping tube 3a is connected to the electric heater plate while the tea serving device is in operation. Even if the steam generated from the hot water heated at step 7 and supplied to the mixing chamber 5 by a hot water supply means 4 which sends out a fixed amount of hot water enters the raw material drop cylinder 6, it is evaporated and no dew condensation occurs. Therefore, the raw material tea does not adhere to the inner surface of the raw material drop tube 3a, and the performance of the raw material drop tube 3a is maintained so that the passage of the raw material tea is not hindered.

The heat generated from other parts of the electric heater plate 7 heats the raw tea storage container 1 through the device of the means 3 for sending out a fixed amount of the raw tea above. For this reason, the contained raw material tea is kept dry and prevented from absorbing moisture from the outside air.

[Example] Embodiments of the present invention will be described with reference to the drawings.
