Description

Technical Field

[0001] This utility model relates to the field of seasoning drying technology, specifically a hot air circulating constant temperature drying oven for seasonings. Background Technology

[0002] The condiment hot air circulating constant temperature drying oven uses a circulating fan motor to drive a fan wheel through a heater to send hot air out, which then goes through an air duct to the inner chamber of the oven. Used air is drawn into the air duct to become the air source for recirculation and heating, ensuring uniform temperature inside the chamber. During the drying process, the hot air in the drying chamber heats the condiments, causing the moisture to turn into water vapor and mix with the hot air. The fan causes the air inside the chamber to circulate through convection, and then the hot air containing water vapor is discharged through the exhaust port. At the same time, the air inlet draws in outside air and heats and circulates inside the chamber, thereby achieving the purpose of drying the condiments.

[0003] Existing hot air circulating constant temperature drying ovens typically discharge hot air along with water vapor from the exhaust vent, and then draw in cold air from the outside for heating, which results in a certain amount of heat waste and increases energy consumption costs. At the same time, the process of heating cold air may also have a certain impact on drying efficiency. Therefore, a hot air circulating constant temperature drying oven for condiments is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hot air circulating constant temperature drying oven for condiments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A condiment hot air circulating constant temperature drying oven includes a main body, an air inlet pipe, and an exhaust pipe. The air inlet pipe is located on the left side of the main body, and the exhaust pipe is located at the top. A guide shell is fixedly connected to the left side of the air inlet pipe, and a protective net is provided on the left side of the guide shell. A first fixing cover is threadedly connected to the outer side of the guide shell, and the protective net is positioned between the first fixing cover and the guide shell. A fixing shell is fixedly connected to the top of the exhaust pipe, and the interior of the fixing shell has three sets of moisture-absorbing layers arranged from bottom to top. The top of the uppermost moisture-absorbing layer is provided with a threaded tube, and a first limiting ring is provided on the outside of the threaded tube. A sealing layer located above the first limiting ring is threadedly connected to the outside of the threaded tube. A second fixing cap threadedly connected to the threaded tube is fixedly connected to the top of the sealing layer, and the inner side of the second fixing cap is threadedly connected to the outer side of the fixing shell. A second limiting ring away from the first limiting ring is fixedly connected to the outside of the threaded tube. A connecting pipe is fixedly connected between the threaded tube and the air inlet pipe. An air inlet fan located on the left side of the hot air circulating constant temperature drying oven body is fixedly connected to the inner side of the air inlet pipe.

[0007] Preferably, the moisture-absorbing layer is cylindrical in shape, and the shape of the moisture-absorbing layer matches the inner shape of the fixed shell. The height of the three moisture-absorbing layers combined together is less than the inner height of the fixed shell.

[0008] Preferably, the bottom end of the sealing layer and the top end of the first limiting ring are in contact with each other, and the diameter of the sealing layer matches the inner diameter of the second fixing cover.

[0009] Preferably, the protective net is disc-shaped, and the diameter of the protective net matches the inner diameter of the first fixed cover.

[0010] Preferably, the guide shell is funnel-shaped, and the diameter of the left side of the guide shell is larger than the diameter of the right side of the guide shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting components such as a fixed shell, a moisture-absorbing layer, a threaded pipe, a sealing layer, a connecting pipe, and an air inlet pipe, the fixed shell and three sets of moisture-absorbing layers can filter the water vapor mixed in the hot air in multiple layers to remove the water vapor. Under the action of the air intake fan, the filtered hot air is accelerated to re-enter the hot air circulation constant temperature drying oven body for multiple cycles, reducing the energy consumption required to reheat the air. This solves the problem that in the existing hot air circulation constant temperature drying oven, the hot air is discharged from the exhaust port along with the water vapor, and then cold air is drawn from the outside for heating, which causes a certain amount of heat waste and increases energy consumption costs. At the same time, the process of heating cold air may also have a certain impact on the drying efficiency.

[0013] 2. In this utility model, the guide shell can guide the external air and accelerate the air intake efficiency of the air intake pipe. By increasing the circulation speed, the drying efficiency can be improved to a certain extent. The protective net can prevent debris from entering the hot air circulation constant temperature drying oven body, causing blockage of the internal pipes and affecting the circulation effect. The protective net can be removed under the action of the first fixed cover, making it easier to clean.

[0014] 3. In this utility model, the second fixed cover and the threaded tube can be rotated and separated without rotating the connecting tube, which is convenient for replacing the moisture-absorbing layer and ensures the adsorption effect on water vapor. The first and second limiting rings can play a limiting role to determine whether the first fixed shell is in a tightened or separated state. The sealing layer mainly plays a sealing role to avoid hot air leakage and waste. Attached Figure Description

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A condiment hot air circulating constant temperature drying oven includes a hot air circulating constant temperature drying oven body 1, an air inlet pipe 2, and an exhaust pipe 3. The air inlet pipe 2 is located on the left side of the hot air circulating constant temperature drying oven body 1, and the exhaust pipe 3 is located at the top of the hot air circulating constant temperature drying oven body 1. A guide shell 4 is fixedly connected to the left side of the air inlet pipe 2, and a protective net 5 is provided on the left side of the guide shell 4. A first fixing cover 6 is threadedly connected to the outer side of the guide shell 4, and the protective net 5 is located between the first fixing cover 6 and the guide shell 4. A fixing shell 7 is fixedly connected to the top of the exhaust pipe 3. The interior of the fixing shell 7 has three sets of moisture-absorbing layers 8 arranged from bottom to top, with the top layer being the moisture-absorbing layer. The top of the moisture-absorbing layer 8 is provided with a threaded tube 9, and the outside of the threaded tube 9 is provided with a first limiting ring 10. The outside of the threaded tube 9 is threadedly connected to a sealing layer 11 located above the first limiting ring 10. The top of the sealing layer 11 is fixedly connected to a second fixing cover 12 threadedly connected to the threaded tube 9, and the inside of the second fixing cover 12 is threadedly connected to the outside of the fixing shell 7. The outside of the threaded tube 9 is fixedly connected to a second limiting ring 13 away from the first limiting ring 10. A connecting pipe 14 is fixedly connected between the threaded tube 9 and the air inlet pipe 2. The inside of the air inlet pipe 2 is fixedly connected to an air inlet fan 15 located on the left side of the hot air circulating constant temperature drying oven body 1.

[0025] The moisture-absorbing layer 8 is cylindrical in shape, and its shape matches the inner shape of the fixing shell 7. The height of the three moisture-absorbing layers 8 combined together is less than the inner height of the fixing shell 7. The moisture-absorbing layer 8 and the fixing shell 7 can better absorb water vapor through their close fit. The taller fixing shell 7 can better hold the first limiting ring 10 after accommodating the moisture-absorbing layer 8, thus ensuring that the sealing layer 11 can be completely fitted to the fixing shell 7. The bottom end of the sealing layer 11 and the top end of the first limiting ring 10 fit together. The diameter of the sealing layer 11 matches the inner diameter of the second fixing cover 12. The first limiting ring 10 and the sealing layer 11 with their matching dimensions can better ensure the sealing effect. The protective net 5 is disc-shaped, and its diameter matches the inner diameter of the first fixing cover 6, preventing debris from creating gaps between the first fixing cover 6 and the protective net 5, which would affect the protective effect. The guide shell 4 is funnel-shaped, and its left diameter is larger than its right diameter, which can better collect and guide external airflow into the air intake pipe 2.

[0026] Workflow: When using a hot air circulating constant temperature drying oven for a condiment, the entire device is powered externally. A protective net 5 protects the air entering the oven body 1 from debris entering the internal pipes. To clean the protective net 5, rotate the first fixed cover 6 to remove it. The airflow through the protective net 5, guided by the guide shell 4, improves the collection efficiency of the air inlet pipe 2, thus increasing the circulation efficiency. The airflow entering the oven body 1 is heated to dry the condiments. The hot air and the water vapor generated during drying are discharged from the exhaust pipe 3, forming a circulating airflow. The water vapor and hot air discharged from the exhaust pipe 3 pass through three moisture-absorbing layers 8. The filtration system and sealing layer 11 prevent hot air from leaking between the second fixed cover 12 and the threaded pipe 9. The hot air, after removing water vapor, is then quickly guided by the intake fan 15 through the connecting pipe 14 and the intake pipe 2 back into the hot air circulation constant temperature drying oven body 1, reducing hot air loss. After a period of use, the second fixed cover 12 can be rotated until it and the second limiting ring 13 are in contact. At this point, the second fixed cover 12 is separated from the fixed shell 7, and the moisture-absorbing layer 8 can be removed for replacement. After replacement, the second fixed cover 12 and the fixed shell 7 are rotated to connect. When the sealing layer 11 and the first limiting ring 10 are in contact, it indicates that the second fixed cover 12 and the fixed shell 7 have been assembled, thus ensuring the dehumidification effect.
