A dryer

Abstract

This utility model provides a dryer. Because the drying fan assembly installed on the shaping conveyor chain can dry and shape the products it conveys, the shaping conveyor chain does not require a second carrying port of a specific size after conveying the dried and shaped products to the drying conveyor chain. Therefore, the size of the second carrying port of the second hanging box of the drying conveyor chain is set to be larger than the size of the first carrying port of the first hanging box of the shaping conveyor chain. Thus, when it is necessary to change to products of different sizes, it is not necessary to change the second hanging box of the drying conveyor chain; only the first hanging box of the shaping conveyor chain needs to be replaced. Compared with existing integrated multi-layer first hanging box dryers, this application has a relatively smaller number of hanging boxes to replace. Therefore, the overall time for changing hanging boxes in this application's dryer is shorter, effectively improving switching efficiency and thus increasing the production efficiency of the products to be dried.

Description

Technical Field

[0001] This utility model relates to the field of food processing, specifically to a dryer. Background Technology

[0002] Non-fried noodles are convenience foods made through processes such as steaming and hot air drying, and their fat and calorie content is significantly lower than that of traditional fried instant noodles. However, existing non-fried noodles are generally dried using an integrated multi-layer first-box dryer, whose first-box chain plate adopts a completely enclosed circular structure. If it is necessary to switch to non-fried noodles of different sizes, the entire first-box chain plate must be removed and a new first-box chain plate must be installed. Therefore, the replacement time of the first-box chain plate in existing integrated multi-layer first-box dryers is long, and the switching efficiency is low, which seriously affects the production efficiency of non-fried noodles.

[0023] The discharge end of the second sub-chain is provided with a second arc-shaped guide rail. The second arc-shaped guide rail is used for the second guide slider to slide in. The second arc-shaped guide rail and the first arc-shaped guide rail are used to make the first hanging box corresponding to the first guide slider and the second guide slider flip over.

[0024] Preferred options also include: skateboards and safety nets;

[0025] The slide plate is positioned at a preset angle between the discharge end of the shaping conveyor chain and the feed end of the drying conveyor chain, with the end of the slide plate closer to the shaping conveyor chain being higher than the other end of the slide plate.

[0026] The protective net is installed at the discharge end of the shaping conveyor chain and is set above the slide plate at preset intervals. The protective net is used to prevent the product to be dried from falling out of the first bearing port, and the preset distance is used for the product to be dried to pass through.

[0027] Preferably, the slide plate is provided with multiple slide grooves, wherein the number of slide grooves is the same as the number of first bearing ports in the first hanging box;

[0028] The chute is equipped with guide rails.

[0029] Preferably, it further includes: a plurality of buffer rollers disposed on both sides of the chute, wherein the plurality of buffer rollers are disposed along the length direction of the chute.

The discharging end of the shaping conveyor chain is located above the feeding end of the drying conveyor chain. The shaping conveyor chain is used to convey the shaped products to be dried onto the drying conveyor chain. Multiple drying fan assemblies are used to supply hot air to the products to be dried on the shaping conveyor chain and the drying conveyor chain. The dryer disclosed above, because the drying fan assembly installed on the shaping conveyor chain can dry and shape the products to be dried, does not require a second bearing port of a specific size after the shaping conveyor chain transports the dried and shaped products to the drying conveyor chain. Therefore, the size of the second bearing port of the second hanging box of the drying conveyor chain is set to be larger than the size of the first bearing port of the first hanging box of the shaping conveyor chain. Thus, when it is necessary to change products of different sizes to be dried, it is not necessary to change the second hanging box of the drying conveyor chain, but only the first hanging box of the shaping conveyor chain needs to be changed. Compared with the existing integrated multi-layer first hanging box dryer, since the number of hanging boxes to be changed is relatively small, the overall time for changing the hanging boxes of the dryer in this application is shorter, which can effectively improve the switching efficiency and thus improve the production efficiency of the products to be dried.

Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] This utility model embodiment provides a dryer, see [link]. Figure 1 and combined Figures 2 to 14 , Figure 1 This is a schematic diagram of the structure of a dryer, which includes: a shell 1, a shaping conveyor chain 2, a drying conveyor chain 3, multiple drying fan assemblies 4, multiple first hanging boxes 5, and multiple second hanging boxes 6;

[0054] Both the shaping conveyor chain 2 and the drying conveyor chain 3 are installed inside the housing 1;

[0055] Multiple first hanging boxes 5 are arranged on the shaping conveyor chain 2, and the first hanging boxes 5 are provided with multiple first carrying ports 51 for placing products to be dried;

[0056] Multiple second hanging boxes 6 are provided on the drying conveyor chain 3. The second hanging boxes 6 are provided with multiple second carrying ports 61 for placing products to be dried. The size of the second carrying port 61 is larger than the size of the first carrying port 51.

[0057] The feeding end of the shaping conveyor chain 2 is located at one end of the housing 1, and the discharging end of the drying conveyor chain 3 is located at the other end of the housing 1;

[0058] The discharge end of the shaping conveyor chain 2 is located above the feed end of the drying conveyor chain 3. The shaping conveyor chain 2 is used to convey the shaped products to be dried to the drying conveyor chain 3.

[0059] Multiple drying fan assemblies 4 are used to deliver hot air to the products to be dried on the shaping conveyor chain 2 and the drying conveyor chain 3.

[0060] It should be noted that the first bearing port 51 of the first hanging box 5 in the shaping conveyor chain 2 of this application is mainly used to carry the unshaped products to be dried. The products to be dried are fed from the feeding end of the shaping conveyor chain 2. During the process of conveying the products to be dried by the shaping conveyor chain 2, the products to be dried are dried and shaped by the drying fan assembly 4, and then conveyed to the drying conveyor chain 3, where the products to be dried are further dried by the drying fan assembly 4.

[0061] It should also be noted that both the shaping conveyor chain 2 and the drying conveyor chain 3 are chain conveyors and are both ring structures. Therefore, both the shaping conveyor chain 2 and the drying conveyor chain 3 have two ends, one end is the feeding end and the other end is the discharging end.

[0062] It is worth noting that the size of the second bearing port 61 of the second hanging box 6 installed in the drying conveyor chain 3 is sufficient to accommodate all sizes of the products to be dried produced. The specific size of the second bearing port 61 is not specifically limited in this application, and those skilled in the art can select it according to their needs.

[0063] In this embodiment of the utility model, both the shaping conveyor chain 2 and the drying conveyor chain 3 are disposed within the housing 1. Multiple first hanging boxes 5 are disposed on the shaping conveyor chain 2, each with multiple first carrying ports 51 for placing products to be dried. Multiple second hanging boxes 6 are disposed on the drying conveyor chain 3, each with multiple second carrying ports 61 for placing products to be dried, and the size of the second carrying ports 61 is larger than the size of the first carrying ports 51. The feeding end of the shaping conveyor chain 2 is located at one end of the housing 1, and the discharging end of the drying conveyor chain 3 is located at the other end of the housing 1. The discharging end of the shaping conveyor chain 2 is located above the feeding end of the drying conveyor chain 3. The shaping conveyor chain 2 is used to convey the shaped products to be dried to the drying conveyor chain 3. Multiple drying fan assemblies 4 are used to supply hot air to the products to be dried on the shaping conveyor chain 2 and the drying conveyor chain 3. With the dryer disclosed above, since the drying fan assembly 4 installed on the shaping conveyor chain 2 can dry and shape the products to be dried, the shaping conveyor chain 2 does not need a second bearing port 61 of a specific size after conveying the dried and shaped products to the drying conveyor chain 3. Therefore, the size of the second bearing port 61 of the second hanging box 6 of the drying conveyor chain 3 is set to be larger than the size of the first bearing port 51 of the first hanging box 5 of the shaping conveyor chain 2. Thus, when it is necessary to change products of different sizes, it is not necessary to change the second hanging box 6 of the drying conveyor chain 3, but only the first hanging box 5 of the shaping conveyor chain 2. Compared with the existing integrated multi-layer first hanging box 5 dryer, since the number of hanging boxes to be changed is relatively small, the overall time for changing the hanging boxes of the dryer in this application is shorter, which can effectively improve the switching efficiency and thus improve the production efficiency of the products to be dried.

[0064] Specifically, the first bearing port 51 is a frustum structure, wherein the bottom diameter of the first bearing port 51 is smaller than the upper diameter of the first bearing port 51.

[0065] It should be noted that setting the first bearing port 51 as a frustum structure and making the bottom diameter of the first bearing port 51 smaller than the top diameter of the first bearing port 51 not only facilitates the entry of the product to be dried into the first bearing port 51, but also reduces the radial dimension of the product to be dried by the structure that is larger at the top and smaller at the bottom.

[0066] Furthermore, the shaping conveyor chain 2 is installed inside the housing 1 after multiple bends from top to bottom;

[0067] The shaping conveyor chain 2 includes: a first sub-chain 21 and a second sub-chain 22;

[0068] The two ends of the first hanging box 5 are respectively rotatably set on the first sub-chain 21 and the second sub-chain 22.

[0069] It should be noted that the shaping conveyor chain 2 is set inside the housing 1 by bending it multiple times from top to bottom, and the shaping conveyor chain 2 is set as the first sub-chain 21 and the second sub-chain 22. The two ends of the first hanging box 5 are respectively rotated and set on the first sub-chain 21 and the second sub-chain 22. Thus, when the first hanging box 5 passes through the bending position, the first hanging box 5 can still ensure that the opening of the first bearing port 51 faces upward, preventing the product to be dried from falling out of the first bearing port 51.

[0070] It is worth noting that, reference Figure 1 In this application, the shaping conveyor chain 2 is set inside the housing 1 through multiple bends from top to bottom. If the left side of the shaping conveyor chain 2 is the feeding end, the bends on the right side of the shaping conveyor chain 2 can all be its discharge end. The following example uses the third bend position on the far right (from top to bottom) as the discharge end.

[0071] Specifically, the first hanging box 5 is provided with a first rotating shaft 52 and a second rotating shaft 53 at both ends;

[0072] The first sub-chain 21 is provided with a first connecting ear 23 on the side near the second sub-chain 22. The first connecting ear 23 has a first movable hole 231 for inserting the first rotating shaft 52.

[0073] The second sub-chain 22 is provided with a second connecting ear 24 on the side near the first sub-chain 21. The second connecting ear 24 has a second movable hole 241 (not shown, please refer to the first movable hole 231) for the insertion of the second rotating shaft 53.

[0074] It should be noted that by setting a first rotating shaft 52 and a second rotating shaft 53 at both ends of the first hanging box 5, and providing a first connecting ear 23 on the side of the first sub-chain 21 near the second sub-chain 22, the first connecting ear 23 has a first movable hole 231 for inserting the first rotating shaft 52, and providing a second connecting ear 24 on the side of the second sub-chain 22 near the first sub-chain 21, the second connecting ear 24 has a second movable hole 241 for inserting the second rotating shaft 53, and thus when the shaping conveyor chain 2 drives the first hanging box 5 to the bending position, the first hanging box 5 rotates relative to the first rotating shaft 52 under its own weight, and the first movable hole 231 rotates relative to the first rotating shaft 52, and the second movable hole 241 rotates relative to the second rotating shaft 53, thereby ensuring that the opening of the first bearing port 51 of the first hanging box 5 always faces upward.

[0075] Specifically, the first hanging box 5 is also provided with a first guide slider 54 and a second guide slider 55 at both ends;

[0076] The first guide slider 54 is located below the first rotating shaft 52;

[0077] The second guide slider 55 is located below the second rotating shaft 53;

[0078] The discharge end of the first sub-chain 21 is provided with a first arc-shaped guide rail 25, which is used for the first guide slider 54 to slide in.

[0079] The discharge end of the second sub-chain 22 is provided with a second arc-shaped guide rail 26. The second arc-shaped guide rail 26 is used for the second guide slider 55 to slide in. The second arc-shaped guide rail 26 and the first arc-shaped guide rail 25 are used to make the first guide slider 54 and the first hanging box 5 corresponding to the second guide slider flip over.

[0080] It should be noted that by setting a first guide slider 54 and a second guide slider 55 at both ends of the first hanging box 5, with the first guide slider 54 located below the first rotating shaft 52 and the second guide slider 55 located below the second rotating shaft 53, and setting a first arc-shaped guide rail 25 at the discharge end of the first sub-chain 21 for the first guide slider 54 to slide into, and setting a second arc-shaped guide rail 26 at the discharge end of the second sub-chain 22 for the second guide slider 55 to slide into, and by using the second arc-shaped guide rail 26 and the first arc-shaped guide rail 25 to make the first hanging box 5 corresponding to the first guide slider 54 and the second guide slider 54 flip, so that the product to be dried located at the first bearing port 51 of the first hanging box 5 can be removed from the first bearing port 51 under its own gravity and enter the drying conveyor chain 3.

[0081] It should also be noted that the first arc-shaped guide rail 25 and the second arc-shaped guide rail 26 have the same bending arc as the discharge end of the first sub-chain 21 and the discharge end of the second sub-chain 22. Therefore, after the first guide slider 54 and the second guide slider 55 of the first hanging box 5 are respectively engaged in the first arc-shaped guide rail 25 and the second arc-shaped guide rail 26, they enter the discharge end under the drive of the first sub-chain 21 and the second sub-chain 22, which can make the first hanging box 5 tilt. When the first hanging box 5 moves to the bottom, the first hanging box 5 completes the flipping.

[0082] It is worth noting that the discharge end of the first sub-chain 21 and the discharge end of the second sub-chain 22 in this application are the discharge ends of the shaping conveyor chain 2.

[0083] Furthermore, the dryer also includes: a sliding plate 7 and a protective net 8;

[0084] The slide plate 7 is set at a preset angle between the discharge end of the shaping conveyor chain 2 and the feed end of the drying conveyor chain 3, and the end of the slide plate 7 closer to the shaping conveyor chain 2 is higher than the other end of the slide plate 7;

[0085] The protective net 8 is set at the discharge end of the shaping conveyor chain 2 and is set above the slide plate 7 at a preset distance. The protective net 8 is used to prevent the product to be dried from falling out of the first bearing port 51, and the preset distance is used for the product to be dried to pass through.

[0086] It should be noted that the slide plate 7 is set at a preset angle between the discharge end of the shaping conveyor chain 2 and the feed end of the drying conveyor chain 3, with the end of the slide plate 7 closer to the shaping conveyor chain 2 being higher than the other end. The guard net 8 is set at the discharge end of the shaping conveyor chain 2 and is positioned above the slide plate 7 at a preset distance. The guard net 8 is used to prevent the product to be dried from falling out of the first bearing port 51. The preset distance is for the product to be dried to pass through. Then, after the first guide slider 54 of the first hanging box 5 enters the first arc-shaped guide rail 25 and its second guide slider 55 enters the second arc-shaped guide rail 26, the first hanging box 5 will gradually tilt. At this time, the product to be dried in the first hanging box 5 may fall out of the first bearing port 51, and the product to be dried after falling out... Since the dried products cannot fall smoothly onto the drying conveyor chain 3, this application provides a protective net 8 at the discharge end of the shaping conveyor chain 2 and positions the protective net 8 above the slide plate 7 at a preset distance. This effectively prevents the products to be dried from falling out of the first bearing port 51. When the first hanging box 5 moves to the gap between the protective net 8 and the slide plate 7, the first hanging box 5 has completely flipped over. The products to be dried in the first bearing port 51 can fall out through the gap between the protective net 8 and the slide plate 7 and smoothly enter the slide plate 7. Since the end of the slide plate 7 closest to the shaping conveyor chain 2 is higher than the other end of the slide plate 7, the products to be dried can slide into the drying conveyor chain 3 under their own gravity, thus achieving a smooth transfer of the products to be dried.

[0087] Specifically, the slide plate 7 is provided with multiple slide grooves 71, wherein the number of slide grooves 71 is the same as the number of first bearing ports 51 in the first hanging box 5;

[0088] The slide 71 is equipped with a guide rail 72.

[0089] It should be noted that by providing multiple troughs 71 on the slide plate 7, and making the number of troughs 71 the same as the number of first bearing ports 51 in the first hanging box 5, multiple products to be dried that have come out of the multiple first bearing ports 51 of the first hanging box 5 can enter the multiple troughs 71 one by one, and then slide in the troughs 71 by their own gravity, and finally slide into the drying conveyor chain 3. The multiple troughs 71 can effectively prevent the products to be dried from colliding with each other and affecting the product appearance.

[0090] It should also be noted that the guide rail 72 in the chute 71 can effectively reduce the contact area between the product to be dried and the chute 71, thereby effectively reducing the resistance of the product to be dried sliding in the chute 71, making the product to be dried descend more smoothly.

[0091] Furthermore, the dryer also includes a plurality of buffer rollers 73 disposed on both sides of the chute 71, wherein the plurality of buffer rollers 73 are disposed along the length direction of the chute 71.

[0092] It should be noted that by setting multiple buffer rollers 73 on both sides of the slide 71 and setting the multiple buffer rollers 73 along the length of the slide 71, the product to be dried can slide down the slide 71 and play a certain buffering role, so as to avoid the product to be dried from hitting the side wall of the slide 71 at too high speed and affecting the product appearance.

[0093] Specifically, the bottom of the first bearing port 51 is provided with a plurality of first vent holes 511 and a plurality of second vent holes 512;

[0094] Multiple first vent holes 511 are disposed in the middle of the first bearing port 51;

[0095] Multiple second vent holes 512 are arranged along multiple first vent holes 511, wherein the diameter of the first vent holes 511 is different from the diameter of the second vent holes 512.

[0096] It should be noted that by providing multiple first vent holes 511 and multiple second vent holes 512 at the bottom of the first bearing port 51, with the multiple first vent holes 511 located in the middle of the first bearing port 51 and the multiple second vent holes 512 arranged along the multiple first vent holes 511, and the diameters of the first vent holes 511 and the second vent holes 512 being different, the hot air blown out by the drying fan assembly 4 can pass through the multiple first vent holes 511 and the multiple second vent holes 512 to quickly dry and shape the product to be dried in the first bearing port 51.

[0097] Furthermore, the dryer also includes: a demolding fan 9;

[0098] The demolding fan 9 is located at the discharge end of the shaping conveyor chain 2 and inside the shaping conveyor chain 2. The demolding fan 9 is used to blow air into the first bearing port 51 of the first hanging box 5 so that the product to be dried can be removed from the first bearing port 51.

[0099] It should be noted that when some of the products to be dried are stuck to or tightly fitted with the first bearing port 51, these products will not come out of the first bearing port 51 due to the first hanging box 5 flipping. Therefore, this application sets the demolding fan 9 at the discharge end of the shaping conveyor chain 2 and inside the shaping conveyor chain 2. The demolding fan 9 blows air into the first bearing port 51 of the first hanging box 5, so that the products to be dried come out of the first bearing port 51.

[0100] Preferably, the diameter of the first vent 511 is larger than the diameter of the second vent 512.

[0101] It should be noted that by setting the diameter of the first vent 511 to be larger than the diameter of the second vent 512, when the demolding blower 9 blows air onto the first bearing port 51, the force on the product to be dried located in the first bearing port 51 gradually decreases from the center to the periphery, causing the product to be dried to gradually separate from the first bearing port 51. This not only prevents the product from deforming, but also effectively separates the product to be dried from the first bearing port 51, allowing the dried product to be removed from the first bearing port 51.

[0102] Preferably, the end of the slide plate 7 near the drying conveyor chain 3 is bent upward to form a horizontal buffer section.

[0103] It should be noted that bending the end of the slide plate 7 near the drying conveyor chain 3 upward to form a horizontal buffer section allows the product to be dried to be slowly transferred from the slide plate 7 to the second bearing port 61 of the second hanging box 6 of the drying conveyor chain 3, thereby preventing the dried product from being damaged by hitting the second bearing port 61 due to excessive speed.

[0104] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
