Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to a continuous drying equipment for natto production. Background Art

[0002] Natto is dried by hot air conveying to reduce the moisture in the natto for easy transportation and storage. However, during the drying process of the natto, one side of the natto is prone to face the hot air for a long time, resulting in uneven drying of the natto, which in turn affects the drying effect of the natto. At the same time, since the surface of the natto contains sugar substances, the natto is also easy to adhere to the surface of the bearing structure during the drying process. The subsequent natto is difficult to fall off the bearing structure, resulting in difficulty in unloading the natto. At the same time, when the natto is piled up, the natto accumulated in the middle cannot directly contact the hot air, resulting in incomplete drying of the natto at this position, while the natto at the bottom is directly in contact with the hot air, resulting in different degrees of drying of the natto in the same batch.

[0003] At the same time, the sticky sugar substances on the surface of natto are easy to remain on the surface of the supporting structure. Long-term drying can easily cause the sugar substances to deteriorate, thereby contaminating the natto during the drying process. Summary of the invention

DETAILED DESCRIPTION

[0018] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] Embodiment 1: A continuous drying device for natto production, such as Figure 1-Figure 5 As shown, it includes an outer sleeve 1, an inner sleeve 2, a feed pipe 3, an air inlet pipe 4 and a baffle 7; the inner sleeve 2 is rotatably connected inside the outer sleeve 1; a storage chamber 2001 is arranged inside the inner sleeve 2; three feed pipes 3 are connected to the outer sleeve 1; a plurality of air inlet pipes 4 are connected to the outer sleeve 1, and each air inlet pipe 4 is connected to an external air pump device; three baffles 7 are arranged inside the outer sleeve 1; It also includes a separation component, a guide piece 5 and a limit plate 6; the outer sleeve 1 and the inner sleeve 2 are commonly connected with a separation component; three guide pieces 5 are installed on the separation component, and each guide piece 5 is made of silicone; a sliding part 5001 is arranged on the lower side of each guide piece 5; each guide piece 5 is slidably connected to the outer sleeve 1 through a spring on the sliding part 5001; a number of sorting slots 2002 are opened on the inner sleeve 2; three limit plates 6 are arranged in the outer sleeve 1; the lower side of each limit plate 6 is connected to the adjacent guide piece 5.

[0020] The separation component includes a swivel 101, a slider 102 and a first filter 104; three swivels 101 are slidably connected to the outer side of the inner sleeve 2; each swivel 101 is fitted with the lower side of the adjacent guide plate 5; a plurality of sliders 102 are fixedly connected to the outer surface of each swivel 101; three first slide grooves 1001 are opened on the inner wall of each outer sleeve 1; each slider 102 slides on the adjacent first slide groove 1001; and a first filter 104 is fixedly connected to each swivel 101.

[0021] It also includes a push rod 103; a plurality of push rods 103 are fixedly connected to the upper side of each partition plate 7.

[0022] It also includes a servo motor 105 , a first gear 106 and a second gear 107 ; the servo motor 105 is fixedly connected to the outer sleeve 1 ; the first gear 106 is fixedly connected to the output end of the servo motor 105 ; the second gear 107 is fixedly connected to the outer surface of the inner sleeve 2 ; the second gear 107 is meshed with the first gear 106 .

[0023] The lower side of the limiting plate 6 is provided with a plurality of convex strips, which squeeze the guide sheet 5 to produce deformation, so as to facilitate the natto adhered to the guide sheet 5 to fall off.

[0024] Several separation balls are arranged on the lower side of the guide sheet 5, and sealing membranes are arranged on the guide sheet 5 and the feed tube 3, so that the natto cannot fall on the guide sheet 5, and the natto can be more easily rubbed and separated, thereby preventing the natto from piling up and sticking during the drying process.

[0025] Each first filter screen 104 is configured to be concave downward in the middle.

[0026] Each first slide groove 1001 on the outer sleeve 1 is configured in a wave shape, so as to facilitate the first filter screen 104 to shake up and down during the sliding process of the slider 102, thereby preventing one side of the natto from adhering to the surface of the first filter screen 104 for a long time.

[0027] The natto is transported between the outer sleeve 1 and the inner sleeve 2 through the feeding tube 3. The sealing membrane provided between the guide sheet 5 and the feeding tube 3 prevents the natto from falling on the guide sheet 5, and then the natto falls on the first filter screen 104. Based on the view from top to bottom, the servo motor 105 is started, and then the first gear 106 is driven to rotate counterclockwise, thereby driving the second gear 107 and the inner sleeve 2 to rotate clockwise. Under the rotation of the inner sleeve 2, the rotating ring 101, the slider 102 and the first filter screen 104 are driven to rotate synchronously, thereby causing the slider 102 to rotate clockwise. Slide on the first slide 1001, and then in the process of feeding through the feeding pipe 3, the natto is spread on the upper side of the first filter screen 104. When the first filter screen 104 rotates a full circle, the feeding pipe 3 stops feeding. At this time, the external pumping equipment is started to pump hot air to all the air inlet pipes 4, and then the hot air is transported from the air inlet pipe 4 to between the outer sleeve 1 and the inner sleeve 2, so that the hot air transported by the air inlet pipe 4 of each layer can only flow upwards under the obstruction of the partition 7, and then the hot air passes through the first filter screen 104 and flows upwards, thereby drying the natto on the first filter screen 104.

[0028] During the drying process of natto, the natto that meets the drying standards is lighter in weight, and the lighter natto can be easily blown upward by the hot air blown out of the air inlet pipe 4, so that the natto floats to the sorting slot 2002 under the guidance of the guide plate 5, so that the natto is collected into the storage chamber 2001 through the sorting slot 2002, and the natto that is not completely dried continues to dry on the first filter 104. When most of the natto is dried and collected in the storage chamber 2001, new natto is added through the feed pipe 3, so that the natto drying process can be completed continuously without stopping the machine, and the natto can be prevented from being over-dried.

[0029] In the above-mentioned screening process for dried and undried natto, considering that there is a layer of sticky sugar substance on the surface of natto, the natto is easy to stick to each other during the drying process. When the natto sticks to each other, even if the mass of the dried natto is relatively light, the overall mass of the dried natto increases when sticking to each other, resulting in the hot air discharged from the air intake pipe 4 being unable to blow up the natto that sticks to each other and collect it into the storage chamber 2001, resulting in the natto being over-dried, and one side of the natto is easily adhered to the first filter screen 104 due to long-term contact with the first filter screen 104 and cannot be blown up, resulting in uneven drying of the natto and affecting the production quality. In order to avoid this phenomenon, when the natto is dried on the first filter screen 104, based on the view from top to bottom, the slider 102 rotates clockwise on the first slide groove 1001, thereby driving the rotating ring 101 and the first filter screen 104 to rotate clockwise. Since the first slide groove 1001 is set in a wave shape, the slider 102 also moves up and down during the sliding process, thereby driving the rotating ring 101 and the first filter screen 104 to shake up and down, thereby shaking the natto located on the first filter screen 104, causing the natto to jump on the first filter screen 104, avoiding the natto from being in contact and adhering to the first filter screen 104 for a long time, and preventing the natto from being over-dried. At the same time, in order to prevent the natto from adhering to each other during the drying process, when the slider 102 drives the rotating ring 101 and the first filter screen 104 to move upward on the first slide groove 1001, the rotating ring 101 also drives the sliding part 5001 to move upward, thereby compressing the spring between the sliding part 5001 and the outer sleeve 1, thereby pushing the lower side of the guide sheet 5 to move upward, so that the guide sheet 5 is attached to the lower side of the limit plate 6, and then the guide sheet 5 is deformed and parallel to the first filter screen 104.

[0030] It should be noted that the initial state of the guide piece 5 is as follows: Figure 2 As shown in the stretched state, when the lower side of the guide sheet 5 moves upward, the guide sheet 5 loses the stretching and contraction of the sliding portion 5001 and the outer sleeve 1, thereby making the guide sheet 5 parallel to the first filter screen 104, and the distance between the guide sheet 5 and the first filter screen 104 can accommodate a natto, and the first filter screen 104 moves upward under the action of the slider 102 while also rotating, and then cooperates with the guide sheet 5 to knead the natto located between the guide sheet 5 and the first filter screen 104, so that the natto is separated under the action of kneading, and when the first filter screen 104 moves downward, the spring between the sliding portion 5001 and the outer sleeve 1 drives the guide sheet 5 to stretch back as shown in the figure. Figure 2state, and the kneaded natto is scattered under the action of the up and down movement of the first filter 104. By kneading the natto for many times, the natto is prevented from sticking to each other during the drying process, and the dried natto is ensured to be blown to the storage chamber 2001 by the hot air, so as to improve the collection effect of the natto, and at the same time ensure that each side of the natto faces the hot air to make it dry more evenly. At the same time, since the sticky sugar substance on the surface of the natto will harden during the drying process, the hardened and bonded natto is also separated by kneading of the guide sheet 5 and the first filter 104, so that the dried natto is smoothly blown up and collected, and the stretched guide sheet 5 is as Figure 3 As shown, the hot air is guided by the lower side of the guide plate 5 to blow toward the sorting tank 2002, thereby guiding the dried natto to blow toward the sorting tank 2002, and finally collected into the storage chamber 2001.

[0031] It is also considered that the viscous sugar substances on the surface of the natto are easy to adhere to the surface of the first filter screen 104. When too much sugar substances adhere to the surface of the first filter screen 104, the filter holes on the first filter screen 104 are blocked, making it difficult for the hot air blown out of the air inlet pipe 4 to pass through the first filter screen 104 to act on the natto, making it difficult for the dried natto to be blown up, and it is difficult to ensure uniform drying of the natto. In addition, the sugar substances accumulated on the first filter screen 104 for a long time are easy to deteriorate and pollute the natto. In order to avoid this phenomenon, when the sugar substances adhere to the first filter screen 104, the filter holes on the first filter screen 104 are blocked. After the sugar material on the holes of the first filter 104 is dried and hardened, when the slider 102 drives the first filter 104 to move downward to the lowest point of the first slide groove 1001, the lower side of the first filter 104 contacts the top rod 103, causing the first filter 104 to sink upward and deform. At the same time, the first filter 104 also rotates, thereby causing the sugar material adhering to the first filter 104 to crack and fall off, and finally collected together in the storage chamber 2001 under the airflow blown out by the air inlet pipe 4, thereby improving the drying effect of the equipment on natto.

[0032] Embodiment 2: on the basis of embodiment 1, as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a connecting rod 201 and a collecting box 202; a plurality of second sliding grooves 2003 are opened in the inner sleeve 2; three collecting boxes 202 are slidably connected in each inner sleeve 2; four connecting rods 201 are fixed on each rotating ring 101; each connecting rod 201 passes through the inner sleeve 2 to support the adjacent collecting box 202.

[0033] A second filter screen 203 is also included; each collection box 202 is fixedly connected with a second filter screen 203 .

[0034] The second filter screen 203 is configured to be conical.

[0035] Since the quality of dried natto is hard and brittle, in order to reduce the falling height of the natto, a collection box 202 is set on the lower side of each layer of sorting slots 2002 in the inner sleeve 2, so that the natto falls on the collection box 202 when it is blown out from the sorting slots 2002, preventing the natto from falling directly to the bottom of the storage chamber 2001 and avoiding the natto from breaking. At the same time, when the collection box 202 is full, the collection box 202 is hooked by an external lifting device and slides upward along the second slide slot 2003, so that the dried natto can be easily taken out, and finally the collection box 202 is placed back to the inner sleeve 2 along the second slide slot 2003, and the corresponding collection box 202 is carried by the connecting rod 201 of each layer.

[0036] It is also considered that the sugar material adhering to the first filter 104 may be over-dried and will be collected into the collection box 202 together with the natto later. In order to reduce the subsequent workers' sorting of the sugar material, a second filter 203 is provided on the collection box 202, so that the natto cannot pass through the second filter 203, and the natto remains on the upper side of the second filter 203. The sugar material is smaller and then passes through the second filter 203 and is collected at the bottom of the collection box 202, thereby reducing labor costs. Since the sugar material is smaller and lighter, the sugar material is blown out from the sorting tank 2002 with less weight than the natto. The sugar flies farther, and the sugar substance flies to the middle of the second filter screen 203, while the natto falls along the conical second filter screen 203 to the side of the collecting box 202, thereby improving the device's ability to screen out sugar substances. At the same time, the slider 102 slides in the first slide groove 1001, driving the rotating ring 101 and the connecting rod 201 to move up and down, thereby driving the collecting box 202 and the second filter screen 203 to shake up and down, so that a small amount of sugar substances accumulated in the natto are screened out from the second filter screen 203 by shaking, further improving the device's ability to screen out sugar substances.

[0037] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
