Description

Technical Field

[0001] The invention belongs to the field of vermicelli preparation, and in particular relates to a vermicelli preparation process. Background Art

[0002] Vermicelli comes in many varieties, including mung bean, pea, broad bean, and konjac varieties. More common are those made from starch, such as sweet potato, yam, and potato. Vermicelli can be thick, thin, round, flat, square, or flaky, depending on the shape. Its main ingredients include beans, potatoes, and sweet potatoes. Depending on the region, vermicelli is called vermicelli, sometimes called vermicelli noodles, sometimes called jelly, or even winter vermicelli, all of which are essentially the same, with similar preparation methods. Vermicelli can be made from any bean starch other than soybean starch, but mung bean starch is considered the best.

[0003] The vermicelli preparation process includes mixing slurry, forming slurry, high temperature aging, low temperature cooling, separation of vermicelli skin, room temperature aging, low temperature aging, vertical cutting into strips, drying, fixed length cross-cutting and packaging. The vermicelli prepared by conventional vermicelli processing equipment is too long, and the vermicelli needs to be cut into segments of equal length, then bent, and then dried and shaped to facilitate subsequent packaging and transportation.

[0025] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0026] A process for preparing vermicelli noodles comprises the following steps:

[0027] Step 1: Prepare the slurry needed for making vermicelli;

[0028] Step 2: Stir the slurry evenly and add it to the preparation device;

[0029] Step 3: Extrude the slurry into a film and steam it;

[0030] Step 4: Dry the steamed paste and cut it into vermicelli;

[0031] Step 5: Dry and shape the vermicelli;

[0032] Step 6: Take out the vermicelli and package it.

[0033] See Figure 2 、 3 , 6 and 9 are schematic diagrams showing an embodiment of the present invention in which vermicelli can be made into a ring shape, eliminating the steps of cutting to length and bending to shape. Further,

[0034] The preparation device includes a preparation box 301, which has two slide rails 304 inside. Both slide rails 304 are slidably connected to a limiting frame 303. Both limiting frames 303 are rotatably connected to rollers 406 through bearings. Both rollers 406 are covered with elastic belts 401, which are silicone belts. One limiting frame 303 is rotatably connected to a rotating frame 501 through a bearing. The rotating frame 501 is rotatably connected to a cutting roller 502 through a bearing. A plurality of air inlet pipes 302 are welded and fixedly connected to the lower end of the preparation box 301, and a box door 308 is hinged on the preparation box 301.

[0035] The staff adds water to the preparation box 301, and then connects multiple air inlet pipes 302 to a hot air blower to discharge hot air into the water, causing the water in the preparation box 301 to boil and generate steam. Then, the slurry needed to prepare vermicelli is applied to the elastic belt 401. By controlling the rotation of one roller 406 and coordinating with another roller 406 to make the elastic belt 401 run, the steam in the preparation box 301 can steam the slurry on the elastic belt 401, and then the slurry is attached to the elastic belt 401 in a film-like shape. At the same time, when the elastic belt 401 is running, the upper and lower surfaces of the slurry can be fully in contact with the steam, so that the slurry is cooked thoroughly. When the slurry is cooked, the staff will drain the water in the preparation box 301 and wait for the cooked slurry to cool and dry naturally. After the slurry is completely shaped, the staff will rotate the rotating frame 501 downward, and the rotating frame 501 will drive the cutting roller 502 to contact the elastic belt 401. When the elastic belt 401 is controlled to operate again, the elastic belt 401 contacts the cutting roller 502, causing the cutting roller 502 to rotate relative to each other, and then the cutting roller 502 can cut the slurry on the elastic belt 401, and then cut the slurry into multiple thin strips of vermicelli. The multiple thin strips of vermicelli are ring-shaped and put on the elastic belt 401, and then dried.

[0036] The box door 308 is opened, and the elastic band 401 is pulled to slide the two limit frames 303 off the two slide rails 304. The elastic band 401 then allows the vermicelli to be removed from the preparation box 301. The staff can then simply remove the vermicelli from the elastic band 401. The ring-shaped vermicelli facilitates packaging and shipping, eliminating the conventional steps of cutting to length and bending to shape, saving time and improving production efficiency. It also avoids waste caused by scraps during cutting.

[0037] See Figure 9 , shows a schematic diagram of an embodiment of the present invention capable of realizing the positioning function of the cutting roller 502, further,

[0038] A torsion spring 503 is welded and fixedly connected between the rotating frame 501 and a limiting frame 303, a rotating handle 505 is welded and fixedly connected to the rotating frame 501, a latch 504 is slidably connected to the rotating handle 505, a hole for sliding the latch 504 is opened on the rotating handle 505, and a positioning hole for inserting the latch 504 is opened on the limiting frame 303.

[0039] The staff pulls out the pin 504 from the positioning hole, and under the action of the torsion spring 503, the rotating frame 501 automatically rotates downward, thereby driving the cutting roller 502 to automatically press against the elastic band 401, facilitating the cutting of the slurry. When the cutting is completed, the staff rotates the handle 505, which drives the rotating frame 501 to rotate, so that the cutting roller 502 is separated from the elastic band 401, and then the pin 504 is inserted into the positioning hole, thereby realizing the positioning function of the cutting roller 502.

[0040] See Figure 8 , shows a schematic diagram of an embodiment of improving the efficiency of vermicelli preparation according to the present invention, further,

[0041] A threaded rod 306 is rotatably connected to one slide rail 304 through a bearing, and the other slide rail 304 is fixedly connected to the inner wall of the preparation box 301 by bolts. The preparation box 301 is provided with an internal thread, and the threaded rod 306 is threadedly connected to the preparation box 301. Two limit plates 305 are welded and fixedly connected to the slide rail 304. The two limit plates 305 are both slidably connected to the preparation box 301. The preparation box 301 is provided with slots for the two limit plates 305 to slide.

[0042] In order to speed up the shaping of vermicelli, the staff can introduce hot air into the preparation box 301 through multiple air inlet pipes 302, thereby drying the vermicelli and improving the production efficiency of vermicelli. By controlling the operation of the elastic belt 401, the vermicelli can be heated evenly. When the vermicelli is dried, it will shrink. In order to prevent the vermicelli from breaking, the staff can rotate the threaded rod 306, and the threaded rod 306 drives two limit plates 305 on a slide rail 304 to slide on the preparation box 301, thereby making one roller 406 approach another roller 406. Since the elastic belt 401 is a silicone belt, under normal conditions the elastic belt 401 is in a state of being stretched by the two rollers 406. When the distance between the two rollers 406 becomes smaller, the elastic belt 401 can shrink accordingly and is still in a state of being stretched by the two rollers 406 without slipping. Therefore, after the elastic belt 401 shrinks, the vermicelli will not break due to drying shrinkage.

[0043] See Figure 8 , shows a schematic diagram of an embodiment of the present invention for facilitating the control of the rotation of the threaded rod 306, further,

[0044] A hexagonal groove 307 is formed at the end of the threaded rod 306 .

[0045] The worker can use a hexagonal wrench to turn the threaded rod 306 .

[0046] See Figure 3 and 10 , shows a schematic diagram of an embodiment of the present invention capable of controlling the operation of the elastic band 401, further,

[0047] A matching shaft 403 is fixedly connected to a rotating roller 406 by bolts, and a slot is provided at the end of the matching shaft 403. A first motor 405 is fixedly connected to the preparation box 301 by bolts, and a plug 404 is fixedly connected to the output shaft of the first motor 405 through a coupling. The plug 404 is slidably connected to the slot of the matching shaft 403.

[0048] Start the first motor 405, the first motor 405 drives the plug 404 to rotate, the plug 404 drives the matching shaft 403 to rotate, and the matching shaft 403 drives a roller 406 to rotate, thereby realizing the function of the elastic band 401 to operate. The installation position of the first motor 405 is outside the preparation box 301, and will not be affected by water vapor. When the vermicelli needs to be taken out, the staff pulls out the two limit frames 303, and the plug 404 is separated from the matching shaft 403. When preparing the vermicelli again, the staff pushes the limit frame 303 into the preparation box 301, so that the plug 404 is reinserted into the slot of the matching shaft 403, thereby realizing the function of the elastic band 401 to operate.

[0049] By controlling the disengagement of the plug 404 from the mating shaft 403, the elastic band 401 can be disabled when the staff takes out the vermicelli, thereby preventing the elastic band 401 from accidentally injuring the staff due to sudden movement, thereby achieving the purpose of protecting the staff.

[0050] See Figure 6 , shows a schematic diagram of an embodiment of the present invention that facilitates staff to pull out the two limiting frames 303, further,

[0051] The two rotating rollers 406 are rotatably connected to the pull seat 402 via bearings.

[0052] The pull seat 402 makes it easy for the staff to pull out the two limiting frames 303 .

[0053] See Figure 2-5 , shows a schematic diagram of evenly laying slurry on the elastic band 401 according to the present invention, further,

[0054] The upper end of the preparation box 301 is fixedly connected to the discharge box 101 by bolts. The interior of the discharge box 101 is a hollow structure. A pressure plate 105 is slidably connected to the discharge box 101. A partition 102 is welded and fixedly connected to the discharge box 101. A feed pipe 104 is welded and fixedly connected to the discharge box 101. A discharge pipe 103 is welded and fixedly connected to the partition 102. Both the feed pipe 104 and the discharge pipe 103 are connected to a one-way valve.

[0055] There is an opening at the bottom of the preparation box 301, and the feed pipe 104 is connected to a container for storing slurry. When the pressing plate 105 slides upward, the one-way valve on the discharge pipe 103 is closed, and the one-way valve on the feed pipe 104 is opened, and then the preparation box 301 sucks the slurry through the feed pipe 104. When the pressing plate 105 slides downward, the one-way valve on the discharge pipe 103 is opened, and the one-way valve on the feed pipe 104 is closed. The slurry in the preparation box 301 is pressed out through the discharge pipe 103, and flows out from the opening at the bottom of the preparation box 301 and falls on the elastic belt 401. At the same time, the elastic belt 401 operates, thereby realizing the function of evenly laying the slurry on the elastic belt 401.

[0056] See Figure 4-5 , showing the intention of the embodiment of the present invention that can control the pressing plate 105 to slide up and down, further,

[0057] The preparation box 301 is fixedly connected to a fixing frame 203 by bolts, the fixing frame 203 is rotatably connected to a lead screw 201 via a bearing, the lead screw 201 is threadedly connected to a lifting portion 202, the lower end of the lifting portion 202 is fixedly connected to the pressure plate 105 by bolts, the fixing frame 203 is fixedly connected to a second motor 205 by bolts, and the lead screw 201 is fixedly connected to the output shaft of the second motor 205 via a coupling.

[0058] The second motor 205 is started, and the second motor 205 drives the lead screw 201 to rotate, and the lead screw 201 drives the lifting part 202 to move up and down, and the lifting part 202 drives the pressing plate 105 to slide up and down.

[0061] The mixing drum 206 is used to store the slurry. When the screw 201 rotates, the stirring paddle 207 is driven to rotate through the pulley 204. Then, when the preparation box 301 extracts the slurry inside the mixing drum 206, the stirring paddle 207 can synchronously stir the slurry inside the mixing drum 206 to avoid precipitation or uneven mixing of the components in the slurry, which affects the quality of the vermicelli.
