Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sweet potato steamer for producing sweet potato shochu.

Traditionally, at potato shochu manufacturing factories, washed and sorted raw potatoes are steamed in a potato steamer and then placed in a preparation vessel for fermentation. The layer is thick (, mountain-shaped and uneven force,
Furthermore, since steam is blown in from below to steam the potatoes, the potatoes in the lower part, which are steamed quickly, deform under the weight of the potatoes in the upper part, and the gaps are closed, making it difficult for the cooling air to pass through smoothly during the cooling process. As the cooling efficiency decreases and the temperature rises during the steaming process, impurities (harmful substances such as tar) are discharged from the potatoes, but as the above-mentioned gaps are crushed, impurities from the upper potatoes are removed. Furthermore, there was a drawback that it required a lot of time and effort to remove the potatoes after steaming and cooling, as workers had to go inside and scrape them out with a shovel.

In order to solve the above-mentioned drawbacks, the present invention is a potato steamer that is equipped with an unloading conveyor at the bottom of the container and has two upper and lower driving trays inside, and the container is divided into two stages to evenly store the potatoes. The flattening prevents the potatoes from deforming, and by blowing steam upwards on the potatoes, impurities such as tar are efficiently removed.The removal of the steamed potatoes is also automated using a delivery conveyor. It is characterized by labor-saving by automating each process such as steaming the potatoes, cooling them, transporting the potatoes, and cleaning the inside of the container.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The container body 1 holds 4 tons of potatoes using an upper tray mechanism 8 and a lower tray mechanism 17.
First, the retractable cylinders 6a on the front and rear sides of the upper tray mechanism 8 are stored separately as 2t and 2t.
, 6a, actuate the retracting cylinders 6b, 6b to retract each rondo so that the central receiving shelves 4a, 4a and the side receiving shelves 4b, 4b are erected in an inclined manner, and the potato feeding cylinder 31 at the upper end of the vessel 1 is The first damper 32a and the second damper 3
2b is opened, and 2 tons of potatoes are carried in by the carry-in conveyor 34. At the same time, the motor 28 is driven to interlock the vertical shaft 25 with the leveling blade shaft 26a.

26b, the potatoes put into the tube 31 are received by each shelf of the upper tray and on the upper surface of the lower tray mechanism 17, and are leveled by the lower leveling blade shaft 26b.
The potatoes are layered thinly and evenly.

After carrying in 2 tons of potatoes, the carrying conveyor 34 is temporarily stopped,
After each tray of the upper pan tray mechanism 8 is horizontally shifted and the lid is closed, 2 tons of potatoes are loaded again by the carry-in conveyor 34 and evenly packed.

After the feeding is completed, the first damper 32a1 and the second damper 32b of the potato feeding cylinder 31 are closed, and the rotation of the leveling blade shaft is stopped.

Steaming operation is started by sending high-temperature steam from the steam pipe 29 to the upper surface of each of the potatoes, which are divided into two upper and lower stages.

At the start of steaming operation, the drain valve 39 of the drain pipe 37
When the valve is opened, the temperature inside the vessel body 1 rises due to the supply of steam, and impurities such as resin are discharged from the inside of each potato. Then, the steam blows through each potato layer for about 30 to 40 minutes, and the temperature sensor installed in the strainer 40 of the drain pipe 37 detects the steam and closes the drain valve 39. At the same time, the valve of the exhaust pulp 41 of the exhaust steam pipe 38 communicated with the drain pipe 37 is opened.Since the components to be recovered into the drain pipe 31 contain high-quality starch, the components are collected through the exhaust steam pipe 38. do.

During the steaming operation, steam is blown from above into the potatoes placed in the upper and lower saucer mechanisms 8 and 11, so compared to the conventional steaming operation in which the steam is blown from below, the potatoes are not deformed, the steam is well permeated, and the steam is shortened. The steaming operation can be completed in a matter of hours, and cold air can be smoothly vented in the subsequent cooling process.

After the potatoes have been steamed for about 1 hour and 10 minutes, the supply of steam from the steam pipe 29 is stopped, the first damper 32a in the potato charging tube 31 is opened, and the damper at the upper end of the cooling pipe 42 is opened. −
The valve 43 is opened and the cooling blower 44 is driven to send cold air into the container body 1. The cold air flows through the gaps between the potatoes of the lower tray mechanism 17 and the upper tray mechanism 8, and then blows the cold air into the container body 1. Each potato is cooled as it is exhausted from the upper end potato input tube 31 through an exhaust duct 35. A temperature sensor installed in the potato input tube 31 detects the exhaust temperature and when the temperature drops below a certain level, a cooling air blower 44 is sent.
The damper 43 is automatically stopped and the damper 43 is closed for approximately 1
The cooling process ends in about 1 hour.

Next, when the steamed potatoes in the container 1 are to be carried out, the delivery tubes 18a, 18 protruding from the front and back of the container 1 are used.
When the doors 22a and 22b of b are opened and carried out in the front direction, the carry-out conveyor 19 is rotated in the front direction by the motor 20, and the ronds of the retraction cylinders 6c and 6c are retracted in the lower tray mechanism 17. while the left and right receiving shelves 14a and 14b in the center are connected to the rotating shafts 1 at both ends.
0c.

The steamed potatoes are rotated downward around the conveyor 10'c to fall onto the upper surface of the conveyor 19 and are conveyed out.
While reciprocally rotating the shafts 11a and 11b toward the center, the potatoes on both sides are dropped onto the left and right receiving shelves 14a and 14b in the center, which are rotating downward. The potatoes in the lower tray mechanism are then transported out using the same unloading conveyor 19.

After carrying out the potatoes on the lower stage, the carrying out conveyor 19 is rotated in the rear direction to carry out the next potato on the upper surface of the upper stage tray mechanism 8, and the central receiving shelves 4a and 4a are connected to the retracting cylinder 6b on the rear side.

6b, and then the side receiving shelves 4b, 4b are tilted and rotated by the front retracting cylinders 6a, 6a, and dropped onto the lower tray mechanism 17, and then transported in the rear direction by the central unloading conveyor 19. It is something to be transported to
It is also possible to efficiently transport the potatoes.

Finally, water is sprayed into the upper and lower saucer mechanisms and the container body from the water supply pipe 30 for cleaning, and water is drained from the drain pipe 37 to complete the cleaning and wait for the potato steaming operation again.

As mentioned above, the potato steamer of the present invention is capable of fully automatically operating the steps of loading potatoes, steaming the potatoes, cooling, taking them out, and washing them. Since the potatoes are leveled and soaked in stages and steam is blown in from above, it is possible to steam a large amount of potatoes in a short time, and the potatoes are not deformed and harmful components such as tar are removed to ensure high quality. It is possible to prepare the ingredients, and achieves the above-mentioned remarkable effects such as achieving automation and labor saving to a degree that cannot be compared with conventional steamers.
