Description

Technical Field

[0001] This utility model relates to the technical field of soybean meal edible film drying device, specifically to a soybean meal edible film drying device. Background Technology

[0002] Soybean meal edible film, as an environmentally friendly food packaging material, is increasingly widely used in the food processing industry. In its production process, the drying process directly determines the film's flatness, strength, and storage resistance, making it a crucial step in ensuring product quality. Existing soybean meal edible film drying equipment mostly uses unidirectional localized heating, with some devices only having heating components at the top. This results in uneven heating of the upper and lower surfaces of the film, easily leading to problems such as the upper surface becoming over-dried and brittle, while the lower surface remains undried and sticks to the conveyor belt, affecting the film's forming quality. Furthermore, the drying process suffers from significant heat loss and low energy utilization. Much of the waste heat generated during drying is directly emitted without being recovered, resulting in energy waste. Additionally, the lack of precise temperature monitoring means that excessively high temperatures can damage the nutrients in the soybean meal, while excessively low temperatures can prolong the drying cycle, thus limiting production efficiency. Utility Model Content

[0003] To address these issues, this invention provides a soybean meal edible film drying device to solve the problems of severe heat loss, low energy utilization, direct emission of waste heat without recovery and utilization, and lack of precise temperature monitoring methods in the existing drying process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: According to a first aspect of the present invention, a soybean meal edible film drying device includes a feeding assembly, a frame, a feeding roller rotatably connected to the inner wall of the frame via bearings, a conveyor belt sleeved on the outer wall of the feeding roller, and a plurality of conveyor belts. The drying assembly includes an upper chamber and a lower chamber, which are fixedly installed on the top and bottom outer walls of the frame. Heating plates are fixedly installed on the inner walls of both the upper and lower chambers. A guide pipe is fixedly installed on the inner wall of the lower chamber, and a fan is fixedly installed at the input end of the guide pipe. The thermal circulation assembly includes an air pump and a flat tube.

[0005] Furthermore, support legs are fixedly installed on the bottom outer wall of the frame, servo motors are fixedly installed on the side walls of the frame, and adjacent feeding rollers are connected by a sprocket and a chain for transmission.

[0006] Furthermore, the output end of the servo motor is connected to the feeding roller via a sprocket and chain drive, and gaps for airflow are provided between adjacent conveyor belts.

[0007] Furthermore, curtains are installed on both the left and right sides of the upper chamber. The curtains are used for the soybean meal edible film to enter and exit the upper chamber and to keep the hot air inside the upper chamber warm.

[0008] Furthermore, the heating plate is mounted on the upper chamber via a spacer, and the guide pipe is located below the bottom heating plate.

[0009] Furthermore, the fan is used to blow air around the heating plate to the soybean meal edible film on the surface of the conveyor belt to dry the soybean meal edible film. The angle between the guide pipe and the surface of the heating plate is °. An air inlet is provided on the bottom inner wall of the lower chamber.

[0010] Furthermore, the air pump is fixedly installed on the top outer wall of the upper chamber, the input end of the air pump is connected to the manifold through the first conduit, the flat tube is fixedly installed on the top inner wall of the upper chamber, and a temperature sensor is fixedly installed on the inner wall of the upper chamber.

[0011] Furthermore, several flat tubes are provided, and the flat tubes are connected to the manifold. Air inlets are evenly opened on the bottom outer wall of the flat tubes. The output end of the air pump is fixedly connected to the inner wall of the lower chamber through a second conduit, which is used to transport the hot air from the top of the upper chamber to the lower chamber for circulating heating.

[0012] This utility model has the following advantages: 1. By installing electric heating plates on the inner walls of both the upper and lower chambers, a bidirectional heating structure is formed. In conjunction with the guide pipe in the lower chamber that forms a 60° angle with the electric heating plate, the hot air delivered by the fan can be precisely blown obliquely onto the edible film of soybean meal on the surface of the conveyor belt. At the same time, the gaps between adjacent conveyor belts ensure that the hot airflow flows vertically, avoiding drying dead corners. In addition, the heat circulation component, consisting of an air pump, a first guide pipe, a manifold, a flat pipe, and a second guide pipe, can recover the waste heat air at the top of the upper chamber and transport it to the lower chamber for recycling, greatly reducing heat waste and lowering energy consumption. 2. The support legs at the bottom of the frame provide stable support for the device and prevent shaking during operation; the servo motor drives the feeding roller to rotate synchronously through the sprocket and chain to ensure smooth conveying of the conveyor belt and prevent wrinkles on the film surface; the curtains on both sides of the upper chamber can reduce the leakage of hot air and maintain a stable temperature inside the chamber.

Detailed Implementation

[0014] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0015] like Figures 1-6 As shown, in the first aspect embodiment of this utility model, a soybean meal edible film drying device includes a feeding assembly, which includes a frame 100. The inner wall of the frame 100 is rotatably connected to a feeding roller 110 via a bearing. The outer wall of the feeding roller 110 is fitted with a conveyor belt 160, and the conveyor belt 160 is provided with a plurality of belts. The drying assembly includes an upper chamber 200 and a lower chamber 240. The upper chamber 200 and the lower chamber 240 are fixedly installed on the top and bottom outer walls of the frame 100. Electric heating plates 221 are fixedly installed on the inner walls of both the upper chamber 200 and the lower chamber 240. A guide pipe 250 is fixedly installed on the inner wall of the lower chamber 240. A fan 260 is fixedly installed at the input end of the guide pipe 250. The heat circulation assembly includes an air pump 300 and a flat tube 330; In the above embodiment, it should be noted that the feeding roller 110, which is rotatably connected to the inner wall of the frame 100 via bearings, starts to rotate, driving several conveyor belts 160 mounted on its outer wall to run synchronously, smoothly conveying the soybean meal edible film to the area between the upper chamber 200 and the lower chamber 240; the electric heating plate 221, which is fixedly installed on the inner wall of the upper chamber 200 and the lower chamber 240, heats up after being powered on, causing the temperature inside the chamber to rise. At the same time, the fan 260, which is fixed on the inner wall of the lower chamber 240, starts, guiding the hot air around the electric heating plate 221 to the soybean meal edible film on the surface of the conveyor belt 160 through the guide pipe 250. The air pump 300 and the flat pipe 330 in the heat circulation component assist the flow of hot air inside the chamber, initially realizing the heating and drying of the soybean meal edible film; The technical effect achieved by the above embodiment is as follows: by cooperating with the upper chamber 200 and the lower chamber 240 to set up the heating plate 221, a bidirectional heating structure is formed. Combined with the hot air delivery by the fan 260 and the guide pipe 250, the edible film of soybean meal on the conveyor belt 160 can be effectively covered, avoiding uneven drying caused by heating in one direction, realizing basic and comprehensive drying functions, and providing structural support for the optimization of subsequent drying effects. Example

[0016] like Figures 1-2 As shown, a soybean meal edible film drying device includes all the contents of Example 1. In addition, the bottom outer wall of the frame 100 is fixedly installed with support legs 120, the side wall of the frame 100 is fixedly installed with servo motor 150, the adjacent feeding rollers 110 are connected by a sprocket 130 and a chain 140, the output end of the servo motor 150 is connected to the feeding rollers 110 by a sprocket 130 and a chain 140, and the gap between adjacent conveyor belts 160 is provided for air flow. In the above embodiments, it should be noted that the support legs 120 fixed to the bottom outer wall of the frame 100 provide stable support for the entire device and prevent shaking during operation; after the servo motor 150 fixed to the side wall of the frame 100 is started, its output end drives the initial feeding roller 110 to rotate through the transmission action of the sprocket 130 and the chain 140. Adjacent feeding rollers 110 are also sequentially driven through the sprocket 130 and the chain 140 to ensure that all feeding rollers 110 rotate synchronously, thereby driving the conveyor belt 160 to smoothly transport the soybean meal edible film; at the same time, the gaps reserved between adjacent conveyor belts 160 for air flow facilitate the mutual circulation of hot air in the upper chamber 200 and the lower chamber 240, and avoid local hot air stagnation. The technical effects achieved by the above embodiments are as follows: the transmission structure of the servo motor 150, sprocket 130 and chain 140 improves the synchronization and stability of the rotation of the feeding roller 110, effectively preventing the conveyor belt 160 from deviating, jamming or uneven speed during conveying; the gaps between the conveyor belts 160 optimize the flow path of hot air, allowing hot air to contact the upper and lower surfaces of the soybean meal edible film more fully, reducing drying dead corners and further improving drying uniformity. Example

[0017] like Figures 3-5 As shown, a soybean meal edible film drying device includes all the contents of Example 2. In addition, curtains 210 are installed on both the left and right sides of the upper chamber 200. The curtains 210 are used for the soybean meal edible film to enter and exit the upper chamber 200 and to keep the hot air inside the upper chamber 200 warm. The electric heating plate 221 is installed in the upper chamber 200 through the bracket 220. The guide pipe 250 is located below the bottom electric heating plate 221. The fan 260 is used to blow the air around the electric heating plate 221 to the soybean meal edible film on the surface of the conveyor belt 160 to dry the soybean meal edible film. The angle between the guide pipe 250 and the surface of the electric heating plate 221 is 60°. An air inlet 241 is opened on the bottom inner wall of the lower chamber 240. In the above embodiments, it should be noted that the curtains 210 installed on the left and right sides of the upper chamber 200 can be opened and closed flexibly when the soybean meal edible film enters and exits the upper chamber 200, and can effectively prevent the loss of hot air inside the upper chamber 200, thus playing a role in heat preservation; the electric heating plate 221 is fixed to the inner wall of the upper chamber 200 by the bracket 220, ensuring that the electric heating plate 221 is firmly installed and maintains a reasonable distance from the chamber wall, which is conducive to heat diffusion; the guide pipe 250 is located below the bottom electric heating plate 221 and is set at a 60° angle with the surface of the electric heating plate 221, so that the hot air delivered by the fan 260 can be more accurately blown obliquely onto the soybean meal edible film on the surface of the conveyor belt 160, improving the utilization rate of hot air; the air inlet 241 opened on the bottom inner wall of the lower chamber 240 continuously replenishes the fan 260 with external air, ensuring a stable supply of hot airflow.

[0018] The technical effects achieved by the above embodiments are as follows: the heat preservation effect of the door curtain 210 significantly reduces heat loss in the warehouse, improves energy utilization, and maintains stable temperature in the warehouse; the setting of the bracket 220 enhances the installation stability of the electric heating plate 221; the 60° angled guide pipe 250 allows hot air to act more efficiently on the soybean meal edible film; combined with the air supplement of the air inlet 241, it avoids the interruption of hot air delivery due to insufficient air intake of the fan 260, greatly improves drying efficiency, and reduces the sticking problem of soybean meal edible film due to incomplete drying. Example

[0019] like Figure 1 and Figure 6As shown, a soybean meal edible film drying device includes all the contents of Example 3.

Several flat tubes 330 are provided. The flat tubes 330 are connected to the manifold 320. Air inlets are evenly opened on the bottom outer wall of the flat tubes 330. The output end of the air pump 300 is fixedly connected to the inner wall of the lower chamber 240 through the second conduit 340 for transporting hot air from the top of the upper chamber 200 to the lower chamber 240 for circulating heating. In the above embodiment, it should be noted that the temperature sensor 230 fixed on the inner wall of the upper chamber 200 monitors the temperature inside the chamber in real time and feeds the temperature data back to the operator so as to facilitate timely adjustment of drying parameters; the air pump 300 is fixed on the top outer wall of the upper chamber 200, and its input end is connected to the manifold 320 through the first conduit 310. The manifold 320 is connected to several flat tubes 330 fixed on the top inner wall of the upper chamber 200. The air inlets evenly opened on the bottom outer wall of the flat tubes 330 can collect the waste heat air at the top of the upper chamber 200; after the air pump 300 is started, the collected waste heat air is transported to the lower chamber 240 through the second conduit 340, and combined with the heat generated by the electric heating plate 221 in the lower chamber 240 to form a hot air circulation and realize the recovery and utilization of waste heat; The technical effects achieved by the above embodiments are as follows: the setting of temperature sensor 230 enables real-time monitoring of drying temperature, avoiding damage to the nutritional components of soybean meal edible film due to excessively high temperature or decreased drying efficiency due to excessively low temperature, thus improving drying accuracy; the heat circulation structure composed of air pump 300, first conduit 310, manifold 320, flat tube 330 and second conduit 340 effectively recovers the residual heat at the top of upper chamber 200, reduces heat waste and energy consumption, and the continuous heat circulation makes the temperature inside the chamber more stable, further ensuring the consistency of soybean meal edible film drying quality.

[0020] Working principle: When used by those skilled in the art, the support leg 120 provides stable support; the servo motor 150 drives the feeding roller 110 to rotate synchronously through the sprocket 130 and chain 140, so that several conveyor belts 160 smoothly transport the soybean meal edible film to the space between the upper chamber 200 and the lower chamber 240, and the gaps between adjacent conveyor belts 160 ensure the flow of hot air; the curtains 210 on both sides of the upper chamber 200 reduce heat loss, and the electric heating plates 221 on the inner walls of the upper chamber 200 and the lower chamber 240 are fixed by the bracket 220 and powered to generate heat. The fan 260 in the lower chamber 240 blows hot air through the guide pipe 2 at a 60° angle to the electric heating plate 221. Air is blown onto the membrane surface by air inlet 241 to replenish air; temperature sensor 230 inside upper chamber 200 monitors temperature in real time; air pump 320 collects residual heat air from upper chamber through first conduit 310, manifold 300, and flat tube 330, and then transports it to lower chamber 240 through second conduit 340 to form a heat cycle, ultimately achieving efficient, uniform, and energy-saving drying of soybean meal edible membrane. All components involved in this utility model are externally connected to controllers in a conventional manner. The above structures and principles are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
