[0003] Typically, the drying device includes an air jet pipe, through which high-speed air generated by the drying device can be sprayed onto the surface of the food to complete the drying process of the food.

The substances attached to the outer wall of the air jet tube may circulate between the food surface and the outer wall of the air jet tube for many times to form black pollutants. The black pollutants may stick to the food surface and cause food contamination. Utility Model Content

[0030] Figure 1 The simplified structural diagram of an existing drying device is used to dry noodle cakes to form hot air dried instant noodles.

[0031] Reference Figure 1 A drying box of the drying device may include a box body 11, and the box body 11 may provide an upper air duct and a lower air duct. The drying box may also include: an upper air injection pipe 12, a lower air injection pipe 13, a drying box 14 and a transmission component 15.

[0032] The upper air injection pipe 12 and the lower air injection pipe 13 are both connected to the box 11. The high-speed wind flowing out of the upper air duct can be sprayed onto the upper surface of the dough cake through the upper air injection pipe 12, and the high-speed wind flowing out of the lower air duct can be sprayed onto the lower surface of the dough cake through the lower air injection pipe 13. The dough cake is placed in the drying box 14, and the drying box 14 is driven to move by the transmission component 15, so that the dough cake is transferred to the drying box for drying.

[0033] When the above drying equipment is used to dry the dough, the fine matter on the dough will adhere to the outer wall of the air jet tube along with the high-speed air flow. Since the outer wall of the air jet tube is difficult to clean, the matter attached to the outer wall of the air jet tube will circulate between the food surface and the outer wall of the air jet tube for many times, forming black contaminants, which may stick to the food surface and cause food contamination.

[0034] To address this problem, the utility model provides a drying device, in which a shielding member is provided, which can isolate the drying area from the outer wall of the air injection tube, thereby shielding the outer wall of the air injection tube to prevent the outer wall of the air injection tube from being contaminated, thereby avoiding the generation of black pollutants, and reducing the occurrence of contamination of the food to be dried.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] The present invention provides a drying device, which includes at least one drying box. The drying box may include: a box body, a plurality of air injection pipes, and a shielding member.

[0037] The box is used to provide an air duct;

[0038] The air injection pipe is fixed on the box body; the air flowing out of the air duct is sprayed toward the surface of the food to be dried through the air injection pipe; a drying area is formed between the pipe openings of the multiple air injection pipes and the surface of the food to be dried;

[0039] The shielding member is connected to the pipe opening of the air injection pipe and is used to isolate the drying area from the outer side wall of the air injection pipe so as to shield the outer side wall of the air injection pipe.

[0040] By arranging a shielding member at the pipe mouth of the air injection pipe, the shielding member isolates the drying area from the outer wall of the air injection pipe, thereby preventing the outer wall of the air injection pipe from being contaminated, thereby avoiding the generation of black pollutants and reducing the occurrence of contamination of the food to be dried.

[0041] In a specific implementation, a heat exchanger and a fan are usually provided in the box, and the heat exchanger and the fan are located on the air duct of the box. The box is also provided with an air inlet. Under the action of the fan, the air outside the box can be sucked in from the air inlet, and high-temperature air (the temperature can reach 120°C) is obtained after passing through the heat exchanger. The high-temperature air is accelerated by the fan and flows out through the air duct. Among them, the heat exchanger can be a steam heat exchanger, that is, the inhaled air is heated with steam as the source to achieve the effect of heating the air.

[0042] The box body may provide at least one air duct, and the air ducts in the box body may use the same heat exchanger and fan. An air jet tube is provided at the air outlet of each air duct. The air jet tube is hollow inside and has any external shape. For example, the external shape of the air jet tube may be cylindrical or rectangular. The air outlet of the air duct is connected to the inside of the air jet tube, and the air flowing out of the air duct may flow out through one end of the air jet tube and spray onto the surface of the food to be dried.

[0043] In one embodiment, referring to Figure 2 , the box 21 may provide only one air duct, in which case the air jet pipe 22 is fixed to the box 21 and communicated with the air outlet of the air duct. The air flowing out of the only air duct in the box 21 may pass through the air jet pipe 22 to one surface of the food to be dried, thereby achieving drying of the food to be dried. Accordingly, a shielding member 23 is provided at the nozzle of the air jet pipe 22, and the shielding member 23 may isolate the drying area from the outer side wall of the air jet pipe 22, thereby achieving shielding of the outer side wall of the air jet pipe 22.

[0044] The food to be dried is placed in the drying box 24 , which can fix the position of the food to be dried so that the food to be dried is kept near the nozzle of the air injection tube 22 .

[0045] It should be noted that the only air duct provided by the box 21 can be located above the food to be dried or below the food to be dried, and there is no limitation here. Accordingly, when the air duct is located above the food to be dried, the air injection pipe 22 is also located above the food to be dried, and the high-speed wind generated by the box 21 is sprayed toward the upper surface of the food to be dried through the air injection pipe 22. When the air duct is located below the food to be dried, the air injection pipe 22 is also located below the food to be dried, and the high-speed wind generated by the box 21 can be sprayed toward the lower surface of the food to be dried through the air injection pipe 22.

[0046] No matter the air jet pipe 22 is located above or below the food to be dried, a shielding member may be provided at the pipe opening of the air jet pipe 22 to shield the outer side wall of the air jet pipe 22 .

[0047] In another embodiment, referring to Figure 3The box body 31 can provide two air ducts, namely an upper air duct and a lower air duct. The upper air duct is arranged opposite to the lower air duct.

[0048] Accordingly, the air injection pipe may include: a first air injection pipe 32 and a second air injection pipe 33. The first air injection pipe 32 is fixed on the box body 31, and the air flowing out of the upper air duct is sprayed toward the upper surface of the food to be dried through the first air injection pipe 32. The second air injection pipe 33 is fixed on the box body 31. The air flowing out of the lower air duct is sprayed toward the lower surface of the food to be dried through the second air injection pipe 33. By respectively arranging air ducts above and below the food to be dried, the upper and lower surfaces of the food to be dried can be dried at the same time, effectively improving the processing efficiency.

[0049] At this time, the shielding member includes: at least one of a first shielding member 34 and a second shielding member 35; the first shielding member 34 is connected to the pipe mouth of the first air jet pipe 32, and is used to isolate the drying area from the outer wall of the first air jet pipe 32 to shield the outer wall of the first air jet pipe 32; the second shielding member 35 is connected to the pipe mouth of the second air jet pipe 33, and is used to isolate the drying area from the outer wall of the second air jet pipe 33 to shield the outer wall of the second air jet pipe 33.

[0050] That is, the first shielding member 34 may be provided only at the nozzle of the first air jet pipe 32, and the second shielding member 35 may not be provided at the nozzle of the second air jet pipe 33. The second shielding member 35 may be provided only at the nozzle of the second air jet pipe 33, and the first shielding member 34 may not be provided at the nozzle of the first air jet pipe 32. The first shielding member 34 may be provided at the nozzle of the first air jet pipe 32, and the second shielding member 35 may be provided at the nozzle of the second air jet pipe 33.

[0051] When a shielding member is only provided at the air injection pipe opening of one air duct, it can only shield the outer side wall of the connected air injection pipe, but cannot shield the outer side wall of the air injection pipe of another air duct. Compared with no shielding member being provided, it can prevent the generation of some black pollutants and contamination of the food to be dried.

[0052] When shielding members are provided at the air injection pipe openings of both air ducts, compared with only providing a shielding member at the air injection pipe opening of one air duct, the generation of some black pollutants and contamination of the food to be dried can be avoided to the greatest extent.

[0053] In a specific implementation, the area of ​​the shielding member can be set according to actual needs. The shielding member can shield the outer side walls of all air injection pipes in the same direction of the food to be dried, or can only shield the outer side walls of some air injection pipes in the same direction of the food to be dried. For example, shielding members can be set only at the pipe openings of some air injection pipes in the same direction of the food to be dried that are easily contaminated, so as to only shield the outer side walls of these air injection pipes.

[0054] In a specific implementation, the shielding member can be implemented in a variety of structures, which are not limited here, as long as it can shield the outer side wall of the air injection pipe.

[0055] In one embodiment of the utility model, the shielding member may be a shielding plate, and the shielding plate has a through hole at a position corresponding to the connected air injection pipe. The through hole on the shielding plate corresponds to the connected air injection pipe.

[0056] Specifically, refer to Figure 3 When the drying device includes both the first shielding member 34 and the second shielding member 35, the first shielding member 34 can be implemented by a first shielding plate, and the first shielding plate has a first through hole at the position corresponding to the nozzle of each first air injection pipe 32. The second shielding member 35 can be implemented by a second shielding plate, and the second shielding plate has a second through hole at the position corresponding to the nozzle of each second air injection pipe 33.

[0057] In a specific implementation, in order not to affect the flow rate of the wind at the air jet pipe orifice, the aperture of the through hole on the shielding plate can be set to be greater than or equal to the outer diameter of the air jet pipe orifice. Specifically, the aperture of the first through hole can be set to be greater than or equal to the outer diameter of the first air jet pipe 32 orifice, and the aperture of the second through hole can be set to be greater than or equal to the outer diameter of the second air jet pipe 33 orifice. In this way, the flow rate of the wind at the air jet pipe orifice can be kept the same as before the shielding member is set. Normally, the flow rate of the wind at the air jet pipe orifice can reach 60m / s.

[0058] In practical applications, the outer diameter of the air jet pipe orifice is about 1 cm. At this time, the apertures of the first through hole and the second through hole can be set to be greater than or equal to 1 cm.

[0059] In a specific implementation, except for the through holes at the positions corresponding to the air injection pipe openings, the other positions on the shielding plate can be airtight structures, that is, the shielding plate area between the air injection pipes is an airtight area. In this way, the wind flowing out of the air injection pipe openings can be kept circulating in the shielding plate and the surface of the food to be dried (i.e., the drying area), and will not flow to the outer wall of the air injection pipe.

[0060] In a specific implementation, the shielding plate can be made of a material that is resistant to high temperatures, airtight, and has high hardness. For example, the shielding plate can be made of a stainless steel plate that meets the requirements of food machinery. The thickness of the shielding plate should be less than the depth of the drying zone (i.e., the distance from the air jet pipe orifice to the surface of the food to be dried). Usually, considering the convenience of mechanical processing operations, a plate with a thickness of 1mm to 2mm and a mechanical strength that meets the requirements can be selected as the shielding plate.

[0061] In a specific implementation, the shielding member can be connected to the air injection pipe orifice in a variety of ways, which are not limited here.

[0062] In one embodiment, the shielding member is welded to the nozzle of the air injection pipe. That is, the shielding member is connected to the nozzle of the air injection pipe by welding. Figure 4 The second shielding member 35 is implemented by a second shielding plate, and the inner wall of the second through hole on the second shielding plate is welded to the outer wall of the corresponding second air injection pipe 33.

[0063] In another embodiment, the shielding member is fixed to the box body via a connecting portion. That is, the drying device further comprises a connecting portion, through which the shielding member can be fixed to the box body.

[0064] Specifically, when the drying device includes a first shielding member and a second shielding member, it may also include a first connecting portion and a second connecting portion, wherein the first shielding member is fixed to the box body through the first connecting portion, and the second shielding member is fixed to the box body through the second connecting portion. The structures of the first connecting portion and the second connecting portion include but are not limited to brackets, etc., as long as the shielding member can be fixed to the box body.

[0065] After the first shielding member is fixed to the box body through the first connecting part, the first through hole on the first shielding member can be connected to the first air injection pipe orifice. After the second shielding member is fixed to the box body through the second connecting part, the second through hole on the second shielding member can be connected to the second air injection pipe orifice.

[0066] In the specific implementation, refer to Figure 3 The food to be dried is placed in a drying box 36, which may include a drying box body 361 and a drying box cover 362. The food to be dried may be placed in the drying box body 361 and covered by the drying box cover 362. The first air injection pipe 32 is located above the drying box cover 362, and the drying box cover 362 has a vent. The air flowing out of the first air injection pipe 32 can be sprayed onto the upper surface of the food to be dried through the vent of the drying box cover 362. The drying box body 361 also has a vent below, and the air flowing out of the second air injection pipe 33 can be sprayed onto the lower surface of the food to be dried through the vent of the drying box body 361.

[0067] After the first shielding member 34 is arranged at the mouth of the first air injection pipe 32, the first shielding member 34 is located above the drying box cover 361 and has a certain distance from the drying box cover 361. At this time, the drying area formed between the first shielding member 34 and the upper surface of the food to be dried is substantially equivalent to the space formed between the upper surface of the drying box cover 361 and the first shielding member 34.

[0068] After the second shielding member 35 is arranged at the mouth of the second air injection pipe 33, the second shielding member 35 is located below the drying box body 362 and has a certain distance from the drying box body 362. At this time, the drying area formed between the second shielding member 34 and the lower surface of the food to be dried is substantially equivalent to the space formed between the lower surface of the drying box body 362 and the second shielding member 35.

[0069] By providing the drying box, the position of the food to be dried can be fixed, thereby keeping the food to be dried below the air jet tube.

[0070] In practical applications, the drying equipment may include a plurality of drying boxes, which are distributed in an array above or below the air injection tube. The same surface of the same drying box may correspond to at least one air injection tube, so that a plurality of air injection tubes may be provided to dry the food to be dried in a plurality of drying boxes at the same time.

[0071] In some embodiments, reference Figure 3 The drying device may include a plurality of drying boxes and a transmission assembly 37. The drying boxes of the drying device to be dried may be connected to the transmission assembly 37, so that the transmission assembly 37 drives the drying boxes to move into each drying box, so as to perform drying treatment in each drying box respectively until the drying requirement is met.

[0072] In a specific implementation, the transmission assembly may include a first transmission assembly and a second transmission assembly, the first transmission assembly may be connected to the drying box body, the second transmission assembly may be connected to the drying box cover, and the first transmission assembly and the second transmission assembly drive the drying box body and the drying box cover to move synchronously.

[0073] In a specific implementation, the drying device may further include a controller and a drive assembly. The controller may be connected to the fan and the heat exchanger in the box to control the temperature after heat exchange and the rotation speed of the fan. The rotation speed of the fan may affect the flow rate of the wind at the air injection pipe. The controller may also be connected to the drive assembly, and the drive assembly may be connected to the transmission assembly, so that the movement speed of the transmission assembly is controlled by controlling the drive assembly, thereby adjusting the drying time.

[0074] In other embodiments, the drying box may include three or more air ducts. The shielding member includes but is not limited to being implemented by a shielding plate, and may also be implemented by a non-plate structure.

[0075] In a specific implementation, the food to be dried includes but is not limited to noodles used to make instant noodles, and may also be other foods.

[0076] From the above content, it can be seen that the drying device in the embodiment of the utility model can reduce the contamination of the outer wall of the air injection pipe by providing a shielding member at the pipe mouth of the air injection pipe, thereby reducing the contamination of the food to be dried.

[0077] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
