Description

[Detailed description of the invention] Industrial application field This Komei melts raw material powder in a spring and discharges it! 1t11 key.

It's not about raccoon dog, but it's about a cooking method that uses a filter to dispense a liquid mixture of raw material flour and phlegm and extracts it from the vending machine.

Conventional technologyVending machines that use this type of cooking method include:
Mention may be made of a coffee vending machine with a five-piece construction that filters and extracts a mixture of coffee powder and lagoon.

The extraction filtration device of this coffee vending machine is shown in Figures 5 to 7.
It is configured as shown in the figure.

In step A of this device, first, as shown in Figure ff15, the communication hole 4 between the upper chamber 2 and the lower chamber 3, which are separated by the partition wall 1, is closed off with the valve body 5, and one cup of ground coffee is mixed with hot water. The phlegm from the tank is introduced into the upper chamber 2. The valve body 5 is connected to a spring 6 as shown in FIG.
As described above, when the mixture of flour, flour, and dry air accumulates in the upper chamber 2, pressurized air by the compressor 8 is sent to the lower chamber 3 from the air supply lower. At this time, it communicates with the lower chamber 3 via the filter 9. 1
a The flow passage 11 of the excess liquid receiver 10 is blocked by an electromagnetic pulp 12, and when pressurized air is sent to the lower chamber 3, the pressure in the lower chamber 3 gradually increases, and the valve body 5 pressurized air leaks into the upper chamber 2 from the gap between the valve body 5 and the gap &P1. The leaked pressurized air bubbles B stir the mixed liquid in the upper chamber 2, promoting the dissolution of the coke and extract into the liquid. When this stirring is continued for a predetermined period of time, the valve body 5 is forcibly pulled up to the position shown by the solid line in FIG. 7, and the mixed liquid in the first chamber 2 is caused to flow down into the lower chamber 3. When the mixed liquid accumulates in the lower chamber 3, the forcible lifting of the valve body 5 is canceled and the communication hole 4 is closed with the valve body 5. Added to the royal family 3
F Air is blown. As a result, the pressure in the space between the partition wall 1 and the mixed liquid increases, and due to the pressure difference between the chamber 3 and the filtrate receiver 10, the =1-hiex in the mixed liquid A is dissolved. The dry component passes through the filter 9 and flows into the downstream passage 11, and the coffee powder containing the extracted coffee extract remains in one part of the filter 9. FIG. 4 shows the flowchart.

Problems to be Solved by the Invention With such conventional extraction and filtration devices, the user cannot select the strength of the coffee to be sold.

An object of the present invention is to provide an extraction filtration device that allows a user to freely select the strength of coffee.

Problem): (Means for solving the problem) The extraction filtration device of the present invention is configured to suck pressurized air into a mixed liquid of raw material powder and salt, stir it, and then filter the mixed liquid with a filter. , and a timer device that can vary the suction time of the pressurized air based on an external instruction from a customer service panel.

Effect According to this configuration, the timer Kl? If you set the timer one hour longer, the time for sucking pressurized air into the mixed liquid will be longer than the one hour, and the coffee will become thicker. If you shorten the timer one hour, the suction of pressurized air into the mixed liquid will be longer. The time will be shorter than the standard time and the coffee will be less strong.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 3. Components having the same functions as those in FIG. 7 showing the conventional example are given the same reference numerals and their explanations will be omitted.

FIG. 1 shows a first embodiment of the present invention, which differs from the conventional apparatus shown in FIGS. 5 to 7 only in the following points. In other words, in the conventional device, the operating time of compressor g8, in other words, the suction time of pressurized air, was a constant FR interval T determined inside the original vending machine, but in this figure 1, the operating time of compressor g8 It is configured such that the time can be changed by setting the timer 1 hour interval 23. Thailand 7-Sou V! I23 has first and second darkness selection switches 24.2! 1 is connected, and no operation of either the first or second darkness selection switch 24.2 is detected at the time the pressurization instruction is detected. %Lg for 1] If the compressor 8 is energized and the mixed M&A is stirred, and the operation of the ml concentration selection switch 24 is detected at the time when the pressurization instruction is detected, the ml concentration selection switch 24 is detected. long time ('T+
t), the compressor 8 is energized to stir the mixed liquid, and when the pressurization instruction is detected, the odor "C2" is immediately emitted.
When the operation of the concentration selection switch 25 is detected, the comprefree 8 is energized for a shorter time (Tt) than the standard time to stir the mixed liquid.

The first and second density selection switches 24 and 25 are provided on a customer service panel (not shown) that is equipped with a coin slot and =1 ram selection button, etc. It is something that can be manipulated at will. - Because of this configuration, if a user desires a dark color, he or she can change the standard time T by operating the first darkness selection switch 24.
If you are a user who wishes to have coffee that is stronger than the fI* concentration that was stirred, you can set the coffee to a higher concentration by operating the second strength selection switch 25. You can receive fermented coffee from 11 degrees.

2 and 3 show a second embodiment. 14 is a hot water tank, which controls the stored water to a predetermined temperature 11/J by a thermostat 15 and a heater 16; 2 to the lower chamber 3. A pipe is wrapped around the outer circumferential surface of the hot water tank 14, and the temperature of the pressurized air from the compressor 8 rises while passing through the pipe 19, which is heated by the tide in the hot water tank 14, causing a back check. valve 2
2 to the air supply []7.

The bolt υ1 filter'A operation is performed by pushing down the valve body 5 to the imaginary line position shown in FIG. First, the coffee powder and lagoon are directly charged into the lower chamber 3, and the compressor 8 is operated to suck warm pressurized air from the air supply lower into the mixture 8A of coffee powder and salt in the lower chamber 3. Mixed liquid A is stirred with pressurized air to promote extraction of coffee extract. When the agitation for a predetermined period is completed, the valve body 5 that has been kept open is opened and the communication hole 4 is opened.
When the chamber is closed, the mixed liquid A is continuously stirred by the pressurized air sucked in from the air supply lower chamber, and the pressure increases in the chamber 3, increasing the pressure between the lower chamber 3 and the filtrate receiver G, +10. Due to the difference, the hot water component in which the Zuhie 4S dissolved in the liquid mixture A passes through the filter 9 and flows into the downstream passage 11, and the coffee powder in the coffee and extract extraction stream remains on the filter 9. FIG. 3 shows a flowchart of the above extraction and filtration operation.

In FIG. 2, the compressor 8 is configured so that the user can select the operating time using the same timer device 23 as in FIG. You can receive coffee and quiet drinks.

Effects of the Invention As described above, according to the present invention, the length of time for sucking pressurized air into the mixed liquid of raw material powder and salt can be changed by an external instruction from the customer service panel. You can get the desired vagueness without having to worry about the amount of raw material flour or hot water required, and the amount to be poured is the same regardless of the density.
