Abstract

PURPOSE:To remove the astringency of many astringent persimmons uniformly in a short time, by feeding air containing an alcoholic component and CO2 to a closed chamber containing air-permeable packaging boxes containing astringent persimmons, and circulating the air through the closed chamber. CONSTITUTION:Air-permeable packaging boxes 2 containing a given amount of astringent persimmons are contained in a closed chamber 1, and the tops of the packaging boxes 2 are covered with a shielding sheet 20 by operating a winding machine 21. A fan 9 in a circulating path 6 is operated to feed air containing an alcoholic component and CO2 from a feed port 7 to the interior of the closed chamber 1, and the main air stream (A) is divided into an secondary air streams (B) in the perpendicular direction by the shielding sheet 20, a rectifying means 16 and the sucking action of a air discharge duct 15. The air streams (B) are sucked through the air discharge duct 15 while in uniform contact with the astringent persimmons in the packaging boxes 2, and then passed through the circulating path 6 to increase the CO2 content. The air is then refed from the feed port 7 into the closed chamber 1.

4.-Also, in the method of removing astringency described in 1-, it is easy to have unevenness in the amount of ice cream and alcohol added to a certain amount of astringent persimmons, and therefore unevenness in removing astringency naturally occurs. , the result is always 1A/L', especially at the bottom of the bag.
Persimmons that are soaked in alcohol and persimmons that are not soaked in alcohol have significant unevenness in removal of astringency; Ta.

In history, there is this! In the JF method, it is possible to simultaneously remove astringency from a large number of astringent persimmons. ．． In addition, considering that the harvest period for astringent persimmons is short, the removal of astringency must be done skillfully in order to achieve fL. 7t The amount of alcohol fluctuates and the occurrence of non-astringent JR etc. and defective products increases as the alcohol content changes.
There was a long-awaited improvement in methods and devices that could remove astringency from a large number of astringent persimmons at the same time, and moreover, in a single piece. .

Embodiments of the present invention will now be described with reference to FIGS. 21 and 7. Figures 2, 3 and 3 are perspective views showing a cross-sectional perspective view and the main piping route of the astringent removal system according to the present invention. This is a sealed chamber formed by a sealed chamber 1, and one end surface of this sealed chamber 1 has a permeable load having a plurality of pieces t on each surface containing astringent persimmons to be removed. A door 3 on the loading/unloading side of the boxes 2, 2... is formed,
Further, a machine room 4 is connected to the other end via a partition wall 5. Note that the air-permeable packing box 2 usually has 2. : Stacked in 3 layers and placed on a pallet for loading and unloading.

A circulation path 6 connected to the sealed chamber 1 in the machine room 4
In this case, a supply lower is provided in the upper part of the compartment i5 of the sealed chamber 1, and a circulation fan 9, 6 is installed in the middle of this passage 6 with exhaust ports 8, 8 opened in the lower part. , many 7-
A heating chamber 1o and d equipped with a heater are equipped with an alcohol vaporizer 11, which is used as needed, and a carbon dioxide gas bottle/vessel, which is a carbon dioxide gas supply means, is installed on the circulation side of the heating chamber 10. 13 is connected via carburetor 1'4
In this case, the alcohol vaporizer 11 has a structure in which an evaporator 12b storing ethyl alcohol is disposed in a chamber 12a formed in the circulation path 6, but the structure is not limited to this structure. For example, as shown in FIG. 4, a pair of ethyl alcohol evaporators 12d and 12d each have built-in electric heating heaters 12c on both sides of the circulation path 6.
A similar effect can be obtained by arranging .

On the other hand, the exhaust area of the circulation path 6 in the sealed chamber 1 is 8°8Kd, and a pair of long and short υ1 air ducts 1'5.15 are connected to it. 1
5' is (a pair of left and right perforated plates 1.6 and '1.5' to be described later).
A short exhaust duct 15 is installed on a partition plate 19 that protrudes into the space surrounded by 6, top & 17, and end plate 18, and bisects the space at the center □. is opened into the space in front □, and the long exhaust duct 15 is opened into the space in front. and ζ these exhaust tacts 15,
A perforated plate t6, which serves as a rectifying means, is provided with a gap on both sides of 15.
It is in a state of being erected.

In this case, the exhaust ducts 15 and 15 are extended in each space to close the end faces, and a plurality of holes 16 are formed on both sides of the exhaust ducts. Rectifying means 1 by drilling 16'...
6 can also be adopted (see Figure 5). Further, the rectifying means 16 is not limited to a perforated plate, but may be a mosquito net-like cloth or a net having good air permeability and a certain resistance (strength).

On the other hand, a winding machine 21 of a tool 20 for shielding and closing is attached to the ceiling at the end of the door 3 of the sealed room 1, and a winding machine 21 for closing and closing is installed on the ceiling at the end of the door 3 of the sealed room 1. /-t.

20 is the end face on the door side, that is, the supply lower, of the air permeability box 2.2, which is stored in J Mitsucho, Hiroshi, and 1 Hei. 2..., and the other MM is the supply lower side end of the sealed chamber 1.

The lower part of the supply lower part, which is fixed to the lower part, has a sea urchin-shaped opening seal l.20.
Prevents the main air flow from flowing directly to the exhaust tact 15 side. things to do,
It is. In addition, by winding up the shielding channel 20 with the winder 21, it becomes possible to take in and take out persimmons from the door 3. 1. The pier-closing sheet 20 and the air-containing cargo box 2 are in a place where nitrogen gas is allowed to pass through. /li only has a lifting platform with a hole (not necessarily 1 degree). Note that 22 is a temperature of 1°, and carbon dioxide gas R is heated to a predetermined temperature in the sealed chamber 1, e.g. When holding, it is for adjusting the heating by the Peter in the heating chamber 10 and the cooling by the cooler 22. 23 is a refrigerator of the cooler 22.
Reference numeral 24 denotes a gas expansion/contraction buffer device, which is composed of a flexible container or the like connected to the sealed chamber 1, so that the gas in the sealed chamber 1 expands due to temperature changes.

This is a safety feature that adjusts the change in volume outdoors when it contracts.

In the astringent removal device according to the present invention constructed as described above, the astringent persimmons to be removed from the air-permeable packing box 2 are loaded into the sealed chamber 1 through the loading/unloading side door 3. After storing the boxes in a specified manner and closing the door 3, the late-closing sort 20 is rolled over by the winder 21 onto the upper surface of the breathable packing box 2゜2.

ILru. Of course, it goes without saying that the rectifying means (6) should be placed in the ducts on both the supply side and the extraction side so that the rectifying effect is reversed (as explained above). How to get rid of astringency of this invention
The astringent persimmons are stored in a breathable packing box in a sealed room containing carbon dioxide-containing air or, if necessary, a carbon dioxide gas envelope containing anol cone components with LL, supply + 1111 or exhaust side. The flow is uniformly rectified by the rectifying means installed in the chamber, and the whole astringent persimmon in the sealed chamber is brought into contact with charcoal or alcohol if necessary, so that the astringency of the astringent persimmon is uniformly removed (- 〃・Also, many θl<persimmons can be reduced to ・short 11,7.
