Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for aspartame production, and in particular to a multi-stage drying device for aspartame production and processing. Background Technology

[0002] Aspartame, a synthetic sweetener, is widely used in the food and beverage industries due to its high sweetness and low calories. Drying is a crucial step in the production and processing of aspartame.

[0003] Existing drying equipment is mostly a simple heating chamber with only a single heating element. This type of equipment can only provide heating at a single temperature and cannot provide suitable temperatures for different stages of aspartame drying. During the drying process, aspartame raw materials often have to be dried at a fixed temperature, without preheating at a low temperature followed by rapid high-temperature drying. This results in poor drying effects, easily leading to localized over-drying and insufficient drying in other areas, severely impacting the quality of the aspartame. Furthermore, traditional drying equipment has an unreasonable airflow design, lacking dedicated blower components and exhaust structures. Air flows slowly within the drying chamber, failing to effectively remove heat from the aspartame raw materials. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes a multi-stage drying device for aspartame production and processing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A multi-stage drying device for aspartame production and processing includes a drying chamber, which comprises a chamber shell and a rear shell. The rear shell is fixedly installed on the rear end face of the chamber shell, and a multi-stage heating plate is rotatably installed in the chamber shell. An angle motor for driving the multi-stage heating plate to rotate is installed in the rear shell. A front cover is fixedly installed on the front end face of the chamber shell, and a multi-layer placement rack is inserted and installed in the middle of the front cover. The multi-layer placement rack is engaged and fixed with the front cover. A blower assembly is also fixedly installed in the rear shell.

[0006] As a preferred embodiment, the housing includes a main housing and an air outlet cover, the air outlet cover being installed on the upper end face of the main housing and being rotatably connected to the main housing.

The secondary shell is fixedly installed on the rear end face of the main shell, and the heat dissipation mesh cover is symmetrically installed on both sides of the secondary shell, and the heat dissipation mesh cover is fixedly connected to the secondary shell.

[0008] As a preferred embodiment, the multi-stage heating plate includes a back plate base, a primary heating plate, and a secondary heating plate. There are two sets of both the primary and secondary heating plates, which are distributed alternately in sequence. Both the primary and secondary heating plates are fixedly installed on the front end face of the back plate base.

[0009] As a preferred embodiment, the front cover includes a cover plate and an auxiliary bracket. The auxiliary bracket is installed on the rear end face of the cover plate and is fixedly connected to the cover plate. The cover plate has a positioning groove in the middle for installing a multi-layer placement rack.

[0010] As a preferred embodiment, the multi-layer placement rack includes an outer frame cover and placement trays. The outer frame cover is installed in a positioning groove, and the placement trays are evenly installed on the inner side of the outer frame cover from top to bottom, and the placement trays are fixedly connected to the outer frame cover.

[0011] As a preferred embodiment, the blower assembly includes a fan, a diverter pipe, and an outlet pipe shell fixedly installed in the housing. The fan is fixedly installed in the sub-housing, and the middle part of the diverter pipe is connected to the fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a multi-stage heating plate, an angle motor, and a front cover in the drying oven, this application facilitates uniform heating during use through the multi-stage heating of the multi-stage heating plate and the rotation driven by the angle motor.

[0021] Reference Figure 1 , Figure 2 and Figure 3As shown, a multi-stage drying device for aspartame production and processing includes a drying chamber 1. The drying chamber 1 includes a chamber shell 11 and a rear shell 12. The rear shell 12 is fixedly installed on the rear end face of the chamber shell 11, and a multi-stage heating plate 2 is rotatably installed in the chamber shell 11. An angle motor 3 that drives the multi-stage heating plate 2 to rotate is installed in the rear shell 12. A front cover 4 is fixedly installed on the front end face of the chamber shell 11. A multi-layer placement rack 5 is inserted and installed in the middle of the front cover 4. The multi-layer placement rack 5 is engaged and fixed with the front cover 4. A blower assembly 6 is also fixedly installed in the rear shell 12. By designing the drying chamber 1 with a fitted outer shell 11 and a rear shell 12, the outer shell 11 serves as the main body for drying the raw material, while the rear shell 12 facilitates installation and use. The multi-stage heating plates 2 enable multi-stage heating, allowing for preheating at a lower temperature followed by rapid drying at a higher temperature, thus improving the drying effect. An angle motor 3 drives the multi-stage heating plates 2, allowing for adjustment of different heating methods and reciprocating rotation within a certain angle during processing, ensuring more even heating of the aspartame raw material. The multi-layer rack 5 can hold multiple containers of aspartame raw material, increasing drying capacity and facilitating even spreading of the material for easier drying. The blower assembly 6 accelerates airflow, further improving the drying effect, and also provides rapid heat dissipation and cooling after drying.

[0022] Reference Figure 2 and Figure 3 As shown, the housing 11 includes a main housing 111 and an air outlet cover 112. The air outlet cover 112 is installed on the upper end face of the main housing 111 and is rotatably connected to the main housing 111. This design allows for convenient cooling after drying by flipping the cover open, and the air outlet direction can be controlled by adjusting the angle of the air outlet cover 112. This allows for adjustment of the airflow direction during the drying process according to actual needs, improving the targeting and uniformity of drying. The rear housing 12 includes a secondary housing 121 and a heat dissipation mesh cover 122. The secondary housing 121 is fixedly installed on the rear end face of the main housing 111, and the heat dissipation mesh cover 122 is symmetrically installed on both sides of the secondary housing 121 and is fixedly connected to the secondary housing 121. The heat dissipation cover 122 can effectively dissipate the heat generated inside the device, ensuring that the internal components of the device work in a suitable temperature environment and extending the service life of the device.

[0023] Reference Figure 2 and Figure 4As shown, the multi-stage heating plate 2 includes a back plate base 21, a primary heating plate 22, and a secondary heating plate 23. There are two sets of both the primary and secondary heating plates 22 and 23, which are spaced apart sequentially. Both the primary and secondary heating plates 22 and 23 are fixedly mounted on the front end face of the back plate base 21. By designing the multi-stage heating plate 2 with the back plate base 21, primary heating plate 22, and secondary heating plate 23 working together, and with the primary and secondary heating plates 22 spaced apart sequentially, two sets of primary heating plates 22 can be used to form a low-temperature preheating structure, while two sets of secondary heating plates 23 can form a high-temperature drying structure. This multi-stage heating structure can provide heating at different temperature levels to meet the needs of aspartame at different drying stages, further improving drying quality.

[0024] Reference Figure 1 and Figure 5 As shown, the front cover 4 includes a cover plate 41 and an auxiliary bracket 42. The auxiliary bracket 42 is installed on the rear end face of the cover plate 41 and is fixedly connected to the cover plate 41. A positioning groove 411 for installing the multi-layer shelf 5 is provided in the middle of the cover plate 41. By designing the front cover 4 into a structure in which the cover plate 41 and the auxiliary bracket 42 cooperate, the auxiliary bracket 42 is fixedly connected to the cover plate 41 during use, and a positioning groove 411 for installing the multi-layer shelf 5 is provided in the middle of the cover plate 41. The auxiliary bracket 42 can support and assist in fixing the multi-layer shelf 5, while the positioning groove 411 ensures the accuracy and stability of the installation of the multi-layer shelf 5, making it convenient for the multi-layer shelf 5 to be inserted into the front cover 4 and used stably.

[0025] Reference Figure 1 and Figure 6 As shown, the multi-layer rack 5 includes an outer cover 51 and placement trays 52. The outer cover 51 is installed in the positioning groove 411, and the placement trays 52 are evenly installed on the inner side of the outer cover 51 from top to bottom, and the placement trays 52 are fixedly connected to the outer cover 51. By designing the multi-layer rack 5 with a structure in which the outer cover 51 and the placement trays 52 cooperate, and with the placement trays 52 evenly installed on the inner side of the outer cover 51, this structural design allows aspartame to be placed in layers, increasing the contact area between aspartame and hot air, improving drying efficiency, and facilitating the overall installation and easy removal of the multi-layer rack 5.

[0026] Reference Figure 2 and Figure 3As shown, the blower assembly 6 includes a fan 61, a distribution pipe 62, and an outlet pipe shell 63 fixedly installed in the housing 11. The fan 61 is fixedly installed in the secondary housing 121, and the distribution pipe 62 is connected to the fan 61 in the middle. The fan 61 provides airflow, which is evenly distributed to the outlet pipe shell 63 through the distribution pipe 62, and then blown onto the aspartame to accelerate the drying process.

[0027] In this embodiment, during actual processing, the aspartame to be dried is placed on the placement tray 52 of the multi-layer placement rack 5. Then, the multi-layer placement rack 5 is inserted into the front cover 4. The angle motor 3 is started to drive the multi-stage heating plate 2 to rotate, and the two sets of primary heating plates 22 are adjusted to the left and right sides of the multi-layer placement rack 5 for heating. After heating for a certain period, the angle motor 3 is started again to drive the multi-stage heating plate 2 to rotate, and the two sets of secondary heating plates 23 are adjusted to the left and right sides of the multi-layer placement rack 5 for high-temperature drying. After high-temperature drying for the set time, the blower 61 of the blower assembly 6 is started. The air generated by the blower 61 is distributed to the air outlet casing 63 through the diverter pipe 62 and then blown onto the aspartame. Simultaneously, the heat dissipation mesh cover 122 is flipped open to dissipate the heat generated inside the device.

[0028] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
