Description

[Detailed description of the invention] The invention mainly involves making high-temperature coffee extract flow down toward a group of ice pieces, and having a direct heat exchange effect when the flowing extract flows down through gaps between the ice pieces. It is used when producing iced coffee by cooling the extract. Specifically, it is placed in the upper part of the ice storage case, and the extract of coffee or other beverages flowing down from above the case is cooled. The present invention relates to a plate-shaped diffusion dripping device for cooling an extract of a favorite beverage such as coffee, which is configured to drip ice chips in a diffused state onto a group of ice chips stored therein.

Taking the coffee mentioned above as an example, in the production of iced coffee it is important to ensure that the taste, richness, aroma, etc. are not impaired, and for this purpose, it is necessary to use a drip type coffee filter etc. Rapid cooling of the resulting hot coffee extract is required. In order to meet this demand, a diffusion dropper 02 is known which has a large number of pores 01 scattered on the bottom wall as shown in FIG. The coffee extract is placed on top of the ice cubes and is rapidly cooled down by spreading it over the ice chips. Because it is necessary to prevent the extract from becoming a passageway, the scattered pores 01 are limited to a very small pore diameter of about 1 mm to 2 mm, and the passage resistance increases accordingly. Coupled with the fact that crosslinking tends to occur within the pores 01 due to surface tension, a certain amount of water head pressure is required to allow the material to pass through the pores 01 smoothly. Therefore, despite the relatively large number of pores provided, rapid cooling is difficult, and coffee extract remains on the top surface of the diffusion dropper after the liquid level drops to the point where the required head pressure cannot be obtained. Therefore, there was a problem that not only was there an economic loss due to this, but also that the residual liquid gave the impression that the value of the iced coffee product itself was reduced.

In addition, as shown in Fig. 9, it has been known to have a water draining tube 03 hanging down on the back side in consideration of the water draining effect at the pore position on the back side, but in this case, Since the actual length of the pores 01 is long, which further increases the flow resistance, there is a drawback that the amount of coffee extract remaining in the diffusion dropper further increases.

In view of the above circumstances, the present invention has an object to eliminate the conventional drawbacks by making extremely simple improvements.

The plate-shaped diffusion dripper for cooling the extract of coffee and other beverages according to the present invention, which is configured to achieve the above object, receives the extract flowing down from above the ice storage case and transfers it to a horizontal surface or A face plate portion that spreads in a substantially horizontal plane, a peripheral locking portion that is locked and held by the case while in close contact with the inner circumferential surface of the case, and a portion of the base plate portion and the peripheral locking portion that are partially connected to each other. A plurality of connecting portions are provided, and a plurality of openings for dripping the diffusion extraction liquid are formed in a state surrounded by adjacent connecting portions in the circumferential direction, the face plate portion, and the peripheral edge locking portion. It is characterized by the presence of

According to the diffusion dropper having the characteristic configuration described above, the flowing extract is received by the face plate portion, and the liquid is spread onto a horizontal or almost horizontal surface by scattering when the liquid is received and by smooth flow along the surface. In addition to smoothly flowing and diffusing the liquid over a wide area within the opening, the diffused liquid is allowed to flow along the edge of the opening without impairing the diffusion state in the face plate, and also to prevent the occurrence of crosslinking phenomenon and the stagnation that accompanies it. This effect can be obtained by smoothly dispersing and dripping the liquid one after another without causing any damage.

Therefore, there is no need for any head pressure for dispersion and dripping, and by simply supplying the liquid down onto the face plate, reliable and sufficient cooling can be achieved by dispersion without creating a path for the liquid to flow through the group of ice pieces. At the same time, it has become possible to avoid losses due to residual liquid and the negative impression of decreased commercial value.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

Although it is not specific to a drip-type coffee filter, an example in which it is applied to this is described as follows: A normal funnel 2 consisting of a server 1 and a funnel 2 placed on top of which is a cup-shaped filter paper. This is a drip type coffee filter, and an iced coffee maker is formed by arranging an ice storage case 3 between the two. (See Figure 1) Next, this ice storage case 3 and funnel 2

It is desirable that the diffusion dropper A is made of a synthetic resin material that has a high affinity for coffee liquid, but it may be made of any material as long as it can achieve the diffusion drop phenomenon.

By arranging them radially, it is configured such that even a funnel 2 with a small seat plate can be placed and used.

Next, to explain how to use this, after putting an appropriate amount of ice pieces group a evenly into the ice storage case 3 at an appropriate thickness, place this on top of the server 1, and place the funnel 2 on top of it. When hot water is poured into the coffee powder in the funnel 2, the coffee liquid flowing down from the funnel 2 is caught by the face plate part 5, and after being diffused in the horizontal plane, it is distributed to each edge of the opening 7... While falling along the ice cubes, the drops are dispersed on the ice pieces group a, and each drop is rapidly cooled one after another by contact with the ice pieces group a. It passes through and flows out into the server 1 from the bottom outlet 11.

If the drip-type coffee filter is not used, only the funnel 2 is used, and high-temperature coffee liquid made with another device is supplied onto the diffusion plate 5 through the funnel 2, or the funnel 2 is It can also be used by removing it and supplying it directly onto the diffusion face plate section 5.

The openings 7 are tilted so that they become lower as they get closer, so that a liquid flow similar to the flow of rainwater in an umbrella can be obtained. The edge 7a is formed into a small wave shape so that the liquid drains easily.

As can be seen from the above embodiments, the diffusion dropper A according to the present invention can naturally be used for teas other than coffee, such as black tea, Japanese tea, etc., by being used in combination with the ice storage case 3. Its uses are not specific to coffee only.
