BEST MODE FOR CARRYING OUT THE INVENTION
Next, the present invention will be described in more detail with reference to FIGS. A squeezing extractor 1 according to the present invention shown in FIG. 1 includes a steam generator 2, a processing chamber 3, a cooler 4, and a circulation processing unit 5. The processing chamber 3 is placed on the steam generator 2, and high-temperature steam passes through the object 100 in the processing chamber 3, and is cooled by the cooler 4 and squeezed into the squeezing tank 51. (Fumigation extract) is accumulated. The target object 100 is, for example, edible wild plants, flowers, trees, bamboo, vegetables, fruits, and the like, such as udon, oily brown, tracing, green bamboo, young bamboo, mandarin orange, and peach. Non-edible substances other than these may also be of interest.
[0011]
The steam generator 2 shown in FIGS. 2 and 3 generally supports a hollow coil-shaped heater 24 via a plurality of insulators 23 provided at appropriate places in a cylindrical container body 21 having a bottom. A power supply 28 is connected between a water inlet 25 on the ground E side at the lower end of the heater 24 and a steam outlet 26 at the upper end, and the entire heater 24 generates heat when energized. The injected water is ejected from the steam outlet 26 as high-temperature steam.
[0012]
One end of the terminal screw 27 is connected to the steam discharge port 26 side by a terminal plate 27a, and the other end penetrates through a side wall of the container body 21 insulated by a cylindrical insulator 27b and fixed by a pair of nuts 27c, 27c. . The connecting portion 31 in the processing chamber 3 is connected via a flange 22 with a bolt or the like (not shown).
[0013]
The processing chamber 3 shown in FIGS. 1 and 3 is configured by sequentially stacking a cylindrical connecting portion 31, an enlarged truncated cone-shaped enlarged portion 32, a processing chamber main body 33 having a large diameter cylindrical shape, and a lid portion having a reduced diameter truncated cone shape. Each layer is connected to a flange as shown by a flange 22 in FIG. 2 by bolts. Each of these layers is formed of steel or stainless steel, and can be changed depending on the amount and shape of the object 100.
[0014]
A member that supports the object 100 and allows water vapor to pass therethrough, such as a perforated metal or a wire net made of the same material as each of the above layers, is laid in the center of the processing chamber main body 33 that is the indoor part 30. Is formed. The steam outlet 26 is located at the center of the container body 21 and the processing chamber body 33, and allows the high-temperature steam to pass through the object 100 on the receiver 35. The upper part of the processing chamber main body 33 is sealed by the lid part 34, and the high-temperature steam from which the extract of the object 100 is extracted is transferred to the cooler 4 from the processing chamber outlet 36.
[0015]
As shown in FIG. 1, the cooler 4 accommodates a long coil-shaped or meandering cooling pipe 42 in a water storage chamber 41. The inlet 43, which is the upper end of the cooling pipe 42, is connected to the processing chamber outlet 36, and the outlet 44, which is the lower end, is connected to the squeezing tank 51. A supply port 45 for supplying cooling water from the water circulator 6 in the circulation processing unit 5 is connected to a lower end of the water storage chamber 41, and a discharge port 46 for returning the cooling water to the water circulator 6 is connected to an upper end thereof. Then, high-temperature steam containing the extract of the object 100 is passed through the cooling pipe 42, cooled by the cooling water in the water storage chamber 41, and discharged from the outlet 44 to the squeezing tank 51.
[0016]
The squeezed liquid accumulated in the squeezed liquid tank 51 is taken out through the faucet 52. Further, there is a case where a part of the flue gas is blown out from the discharge port 44 into the squeezing tank 51, and this flue gas is sent out to the flue gas treatment device 7 in the circulation processing unit 5 via the flue gas pipe 53. , Smoke is removed by the filter. It is sufficient to provide the smoke exhaust treatment device 7 as needed. The water circulation device 6 and the smoke exhaust treatment device 7 can be installed as a part of the function of the circulation treatment unit 5. For example, cooling water may be used for the flue gas treatment device, and the cooling water circulation device may be used as the water circulator 6.
[0017]
In use, the target object 100 is bundled with a string or a wire, placed on the placing section 35, and the lid section 34 is closed. Depending on the type of the object 100, these may be wrapped with a wire net and placed on the placement unit 35. Then, while supplying a certain amount of pure water to the steam generator 2, the heater 24 is energized by the power supply 28 to generate high-temperature steam. The circulation processing unit 5 is operated to circulate the cooling water of the water circulator 6 to the cooler 4, to take the squeezed liquid into the squeezed tank 51, and to perform the smoke exhaust treatment by the smoke exhaust processor 7. Since the squeezed liquid is oxidized with the progress of the treatment time, the pH is appropriately measured at the outlet of the outlet 44, and the treatment is terminated when the pH exceeds a certain value.
[0018]
Next, another embodiment of the present invention will be described below. The same members as those in the above embodiment are denoted by the same reference numerals.
In the second embodiment shown in FIG. 4, a modified example of the steam generator 2 is shown. The direction of the heater 64 is different from that in the above embodiment, and the water supplied from the water inlet 65 attached to the upper part of the container main body 21 is heated and ejected from the steam outlet 66 below the heater 64. The negative electrode of the power supply 28 is connected to the water inlet 65 on the ground E side, and the positive electrode of the power supply 28 is connected to the steam discharge port 66 via the terminal screw 67 and the terminal plate 67a. According to this configuration, the high-temperature steam spouted from the steam outlet 66, which is the lower part of the center of the container body 21 in the planar direction, is further expanded from the previous embodiment in a state in which the temperature is maintained by the heater 64 and the processing chamber 3 Is supplied to the mounting portion 35. In this case, the connecting portion 31 can be omitted.
[0019]
In the above-described embodiment, high-temperature steam is passed through the cooling pipe 42 in the cooler 4 and is cooled by external cooling water. However, high-temperature steam may be supplied to the room, and cooling water may be passed through the pipe to cool the high-temperature steam. Further, the cooler 4 is not limited to the water cooling system. Instead of the water circulator 6 for circulating the cooling water to the cooler 4, river water can be taken into the cooler 4. In addition, if emission to the atmosphere is possible, the flue gas treatment device 7 is unnecessary.
[0020]
In the above embodiment, the steam generator 2 is configured using a hollow tubular heater. However, the steam generator 2 may use a heating wire or a sheet heater, or may use another type of combustion-type heat source without using electric heating.
[0021]
In the above-described embodiment, the processing chamber 3 is stacked on the steam generator 2, but these may be separated so as to supply high-temperature steam by a pipe or the like. However, the above embodiment is excellent in terms of thermal efficiency.
[0022]
【Example】
Next, examples of the present invention will be described. Plants such as "Tadori", "Aburakoshi", "Udo", "Aotake" and the like were used as the object 100 for squeezed liquid extraction. The target object weight is about 30 kg. Further, as the steam generator 2, a heater having a water consumption of 10 liter / h (hour) was used. The steam temperature inside the processing chamber 3 was about 105 degrees Celsius. The temperature of the high-temperature steam can be appropriately changed according to the type of the object 100. According to the steam generator, what is included in the squeezed water in the supply water is about 40 to 60%. Therefore, 4 to 6 liters of 10 liters of feed water were included in the squeezed liquid.
[0023]
After several hours of treatment, approximately 50 liters of a nearly transparent squeeze were obtained. The pH value was about 3.8-4 on the whole average. Further, the extract was extracted from the object 100, and only a very small amount of fibrous material remained.
[0024]
