Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, it relates to a raw material drying device for condiment production. Background Technology

[0002] Seasonings can adjust the flavor of dishes, mask fishy smells, enhance umami, improve the quality of dishes, and stimulate appetite. They are an indispensable ingredient in modern family cooking.

[0003] The production of seasonings requires multiple processing steps for raw materials, including washing, drying, and grinding. Drying typically requires the use of drying equipment, which utilizes the high temperatures inside to process the raw materials. During actual processing, the raw materials accumulate in the drying equipment to undergo high-temperature treatment. Common drying equipment heats from the outside in, resulting in the outer layers of raw materials being heated earlier, while the inner materials, being separated, receive heat more slowly. This leads to uneven heating and drying. After the inner materials are dried, the outer materials endure prolonged drying, which can negatively impact the taste and quality of the seasoning. Furthermore, existing drying equipment, in order to ensure drying efficiency... The process of drying seasonings involves more than just simple heating. It also involves adding fans to guide gas flow, working with heating equipment to create a hot airflow that dries the raw materials. However, the exhaust gas generated in this way is directly discharged into the external environment after drying. This exhaust gas still carries a certain amount of heat and is more stable than the external environment. Directly releasing this heat into the external environment easily leads to resource waste. Furthermore, seasoning raw materials often contain impurities. These impurities adhere to or are encapsulated by the raw materials. Common drying systems are functionally limited and lack screening structures, failing to filter out these impurities. This affects the quality of the dried raw materials, requiring additional filtration equipment for screening, thus reducing the efficiency of seasoning production. Utility Model Content

[0030] Please see Figure 1-5 A raw material drying device for condiment production includes a frame 1, a drying box 2 on the frame 1, a support frame 3 rotatably connected inside the drying box 2, a drive motor 4 at the outer end of the drying box 2, the drive motor 4 cooperating with the support frame 3, a support rod 5 fixedly connected inside the drying box 2, the support rod 5 rotating with the axis of the support frame 3, and a stirring blade 6 on the support rod 5.

[0031] The upper end of the drying oven 2 is equipped with a fan 7, and one end of the fan 7 is equipped with a heating box 8. One end of the heating box 8 is connected to the fan 7, and the other end is connected to the inside of the drying oven 2. The lower end of the drying oven 2 on the side away from the heating box 8 is equipped with an exhaust pipe 9. One end of the exhaust pipe 9 is equipped with a tail gas treatment box 10, and one end of the tail gas treatment box 10 is equipped with a return pipe 11. The return pipe 11 is connected to the fan 7.

[0032] In this embodiment, the equipment is supported by the frame 1 and the drying structure is provided by the drying box 2. During use, the raw materials to be dried are loaded into the drying box 2 and supported by the support frame 3. During drying, the drive motor 4 is activated, which drives the support frame 3 to rotate. The support frame 3 carries the raw materials and rotates them, causing the raw materials to move upward along the inner wall of the support frame 3. Then, due to gravity, the raw materials fall, causing them to flip and disperse. The support rod 5 rotates relative to the support frame 3, causing the stirring blade 6 to stir the raw materials, thereby ensuring that the raw materials are heated evenly and the drying quality is guaranteed.

[0033] More specifically, the blower 7 provides negative pressure, causing airflow to flow into the drying chamber 2. The heating chamber 8 provides a heating structure, which heats the flowing gas, turning it into hot airflow that enters the drying chamber 2 for drying. The dried airflow flows out from the exhaust pipe 9, and after being processed by the exhaust gas treatment box 10 to remove internal moisture and other impurities, it flows back to the blower 7 along the return pipe 11, realizing the recycling and reuse of the drying airflow.

[0034] Please see Figures 1-4 As one method of screening raw materials: the support frame 3 is provided with an air vent 12, the air vent 12 is provided with a filter screen 13, the lower end of the drying box 2 is provided with a collection frame 14, and the collection frame 14 is provided with a collection box 15.

[0035] Specifically, when the support frame 3 rotates with the raw materials inside for drying, hot air flows through the vent 12 to ensure the raw materials are heated, while the filter screen 13 prevents the raw materials from falling out of the support frame 3, ensuring stable processing of the raw materials. During the agitation of the drying box, impurities and debris in the raw materials will separate from the raw materials, pass through the filter screen 13, leave the support frame 3, separate from the raw materials, and fall into the drying box 2. Guided by the bottom surface of the drying box 2, they fall into the collection frame 14 and are collected by the collection box 15.

[0036] Please see Figures 1-4 As a further embodiment of the collection box: the collection box 15 is slidably fitted with the collection frame 14, and one end of the collection box 15 is provided with a mounting plate 16. The mounting plate 16 is detachably connected to the collection frame 14 by a bolt structure. A sealing gasket 17 is provided on the inner side of the mounting plate 16, and a protective net 18 is provided at the connection between the exhaust pipe 9 and the drying box 2.

[0037] Specifically, the collection box 15 and the collection frame 14 are slidably engaged, allowing the collection box 15 to be pulled out for cleaning of the collected impurities. During operation, the collection box 15 is fixed in place by the engagement of the mounting plate 16 and the collection frame 14, and the mounting plate 16 is tightly attached to the collection frame 14 by the sealing gasket 17 to ensure a sealing effect and prevent gas leakage. In addition, the protective net 18 prevents impurities from entering the exhaust pipe 9, facilitating the collection of impurities.

[0038] Please see Figure 2 As a further embodiment of the support frame: a rotating ring 19 is provided at one end of the support frame 3, and the support frame 3 is rotatably engaged with the drying box 2 through the rotating ring 19. A drive ring 20 is provided at the outer end of the rotating ring 19, and a drive wheel 21 is provided at the output end of the drive motor 4. The drive wheel 21 is engaged with the drive ring 20.

[0039] Specifically, when the drive motor 4 is working, its output end drives the drive wheel 21 to rotate. Through the cooperation between the drive wheel 21 and the drive ring 20, the transmission is carried out, causing the rotating ring 19 to rotate, thereby causing the bearing frame 3 to rotate, and without conflicting with the support rod 5.

[0040] Please refer to 5, as a further embodiment of the support frame: the support frame 3 is provided with a stirring rod 22, and multiple stirring rods 22 are provided and evenly distributed on the inner side of the support frame 3. The stirring rod 22 is provided with a stirring blade 23, and the stirring blade 23 cooperates with the stirring blade 6.

[0041] Specifically, when the carrier frame 3 rotates, it will drive the stirring rod 22 to rotate. The stirring rod 22 comes into contact with the raw materials through the stirring blade 23, making it easier to tumble the raw materials. Moreover, the stirring blade 23 and the stirring blade 6 are staggered, so they will not conflict when rotating and will cooperate with each other to more thoroughly stir the seasoning raw materials.

[0042] Please see Figures 1-3 As a further embodiment of the drying oven: the drying oven 2 is rotatably connected to a cover 24 at the end away from the drive motor 4, and a frame cover 25 is rotatably connected to the inside of the cover 24, and the frame cover 25 cooperates with the support frame 3.

[0043] Specifically, the box cover 24 provides a protective structure. Rotating the box cover 24 closes the box cover 24, blocking one end of the drying box 2. The frame cover 25 will contact the support frame 3, blocking the support frame 3 and preventing the raw materials from leaking out. When the support frame 3 rotates, the frame cover 25 will rotate along with it.

[0044] Please see Figure 1 As a further embodiment of the lid: a first sealing ring 26 is provided on the inner side of the lid 24, and the lid 24 cooperates with the drying oven 2 through the first sealing ring 26; a second sealing ring 27 is provided on the inner side of the frame cover 25, and the frame cover 25 cooperates with the support frame 3 through the second sealing ring 27.

[0045] Specifically, the lid 24 is tightly attached to the outer end of the drying chamber 2 via the first sealing ring 26 to provide a sealing structure and prevent hot air from escaping, and the frame cover 25 is tightly attached to the support frame 3 via the second sealing ring 27 to provide a closed structure to prevent raw material leakage.

[0046] Please see Figure 1 and Figure 5As a further embodiment of the drying oven: the drying oven 2 is provided with a support frame 28, and a support wheel 29 is rotatably connected on the support frame 28, and the support wheel 29 cooperates with the bearing frame 3.

[0047] Specifically, the support frame 28 provides support, allowing the support wheel 29 to contact the load-bearing frame 3 and support the load-bearing frame 3 to maintain its stability. When the load-bearing frame 3 rotates, the support wheel 29 will rotate on the support frame 28, reducing the impact of friction.

[0048] In summary, during the use or operation of the overall equipment:

[0049] When using the equipment, the frame 1 supports the equipment, and the drying chamber 2 provides the drying structure. The chamber lid 24 is opened, and the seasoning ingredients to be dried are loaded into the support frame 3. Then, the lid 24 is closed, ensuring it is tightly sealed to the drying chamber 2 via the first sealing ring 26, preventing hot air from escaping during drying. When the lid 24 is closed, the frame cover 25 contacts the support frame 3 via the second sealing ring 27, blocking the support frame 3 and preventing material leakage. During use, the support frame 28 provides support, and the support wheels 29 contact the support frame 3, supporting and stabilizing it. The support frame 3 supports the materials. Hot air is introduced into the drying chamber 2, causing the internal temperature to rise steadily. Simultaneously, the drive motor 4 is activated, and its output drives the drive wheel 21 to rotate. Through the interaction of the drive wheel 21 and the drive ring 20, the rotating ring 19 rotates, causing the support frame 3 to rotate without interfering with the support rod 5. When the load cell rotates, the support frame 3 rotates along with the raw materials, causing them to move upwards along the inner wall of the support frame 3. Then, due to gravity, the raw materials fall, causing them to tumble and disperse. The support rod 5 rotates relative to the support frame 3, causing the stirring blade 6 to stir the raw materials. When the support frame 3 rotates, it also drives the stirring rod 22 to rotate. The stirring rod 22 contacts the raw materials through the stirring blade 23, making it easier to tumble the raw materials. The stirring blade 23 and the stirring blade 6 are staggered, so there is no conflict during rotation. They cooperate with each other to more thoroughly stir the seasoning raw materials, so that the raw materials are heated evenly and the drying quality is guaranteed. In addition, when the support frame 3 rotates, the frame cover 25 will rotate with it without interference. It is supported by the support frame 28, and the support wheel 29 contacts the support frame 3 to support the support frame 3 and keep it stable. When the support frame 3 rotates, the support wheel 29 will rotate on the support frame 28 to reduce the impact of friction.

[0050] During the drying process, the blower 7 operates to provide negative pressure, causing airflow into the drying chamber 2. The heating chamber 8 provides a heating structure, heating the flowing gas and turning it into hot airflow that enters the drying chamber 2 for drying. The hot airflow flows along the drying chamber 2, passing through the vent 12 to ensure the raw material is heated, and slowly flows towards the exhaust pipe 9 at the other end. The dried airflow exits from the exhaust pipe 9 and then passes through the exhaust gas treatment chamber 10 to remove internal moisture and impurities. It then flows back to the blower 7 along the return pipe 11, achieving the recycling and reuse of the dried airflow. Additionally, the filter screen 13 prevents the raw material from detaching from the support frame 3 through the vent 12. To ensure stable raw material processing, during the agitation in the drying box, impurities and debris in the raw materials will separate from the raw materials, pass through the filter screen 13, and leave the support frame 3, falling into the drying chamber 2. Guided by the bottom surface of the drying chamber 2, they fall into the collection frame 14 and are collected by the collection box 15. The collection box 15 and the collection frame 14 slide together, allowing the collection box 15 to be pulled out for cleaning the collected impurities. During operation, the collection box 15 is fixed by the cooperation of the mounting plate 16 and the collection frame 14, and the mounting plate 16 is tightly attached to the collection frame 14 through the sealing gasket 17 to ensure a sealing effect and prevent gas leakage. In addition, the protective net 18 will prevent impurities from entering the exhaust pipe 9, facilitating the collection of impurities.
