Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent papaya processing systems, specifically to an intelligent papaya processing system and method based on AI vision and composite drying technology. Background Technology
[0002] The intelligent papaya processing system based on AI vision and composite drying technology mainly comprises three key components: an AI vision recognition system, a composite drying system, and an automated cutting and packaging system. First, the AI vision recognition system intelligently classifies papayas to ensure their quality and size meet processing standards. This system uses high-definition cameras and deep learning algorithms for image analysis, automatically identifying the ripeness and appearance defects of the papayas to avoid human error. Second, the composite drying system combines oven drying and sun drying processes. It uses an adjustable temperature-controlled forced-air oven for initial drying, combined with sun drying, ensuring the papayas are processed under suitable temperature and humidity to prevent over-drying or mold growth. Finally, the automated cutting and packaging system automatically cuts the dried papayas into thin slices and packages them, effectively reducing manual operation and improving processing efficiency and product consistency.
[0003] While the system offers significant advantages in improving papaya processing efficiency and quality, it still has some drawbacks. First, the AI vision system may misidentify papayas with varying degrees of surface damage or irregular shapes, leading to substandard papayas entering the processing flow. Although the composite drying process improves drying efficiency, excessively high humidity or low temperature can affect the sun-dried portions, resulting in inconsistent drying outcomes. Finally, the automated cutting system may not adapt to the natural shape variations of papayas, potentially wasting some product or affecting the aesthetic appearance of the finished product. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an intelligent papaya processing system and method based on AI vision and composite drying technology. This solves the problem that when faced with papayas with varying degrees of surface damage or irregular shapes, recognition errors can easily occur, leading to substandard papayas entering the processing flow. Furthermore, when the humidity is too high or the temperature is too low, the parts that rely on sun drying may be affected, resulting in unstable drying effects.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent papaya processing system and method based on AI vision and composite drying technology, comprising:

[0008] An automated cutting and packaging system is used to cut dried papayas into thin slices and package them.
[0009] The AI visual recognition system uses a deep learning model to identify the surface features of papayas and combines them with preset recognition rules to judge whether the papaya surface is damaged or has an irregular shape, thereby improving the recognition accuracy.
[0010] Preferably, the AI visual recognition system is trained using a convolutional neural network algorithm, and the trained model is optimized using a papaya image dataset containing different damage types and shapes to enhance the system's ability to recognize different degrees of damage on the papaya surface.

[0013] The sun-drying area is used to combine sun drying with controlled humidity and temperature to ensure that the papayas are dried to the required moisture content.
[0014] Preferably, the AI visual recognition system includes a camera, an image processing unit, and a deep learning model. It can classify papayas based on real-time image data, automatically screening out substandard papayas to prevent them from entering subsequent processing steps. The deep learning model employs a hybrid model combining multi-layer convolutional neural networks and long short-term memory networks. It dynamically optimizes and controls the drying and cutting processes by processing papaya images and environmental data in real time. The deep learning model is optimized using the following formula:
[0015]
[0016] Where y(t) is the optimized output at the current time, and w i The weights for each input feature, x i (t) represents the papaya image features and environmental data at the current moment, and b represents the bias term. By combining the temporal prediction model of the Long Short-Term Memory Network, the humidity and temperature control during the drying process are optimized to achieve a stable drying effect over a long period of time.
[0017] A method for intelligently processing papaya based on AI vision and composite drying technology includes the following steps:
[0018] a. Papaya harvesting and cleaning: After the papayas are harvested from the plantation, they are cleaned to remove surface dirt and impurities;
[0019] b. Papaya appearance inspection: The appearance of the papaya is detected using an AI visual recognition system and compared with the training dataset to identify the ripeness, surface damage and irregular shape of the papaya.
[0020] c. Papaya classification: Based on the test results in step b, the papayas are divided into two categories: qualified and unqualified. Unqualified papayas are automatically removed.
[0021] d. Blanching: Place qualified papayas into boiling water and blanch for 2 to 7 minutes, until the peel turns grayish-white and the flesh is cooked.
[0022] e. Preliminary drying: Place the scalded papaya in a forced-air drying oven and set the temperature to 50℃ to 80℃ for preliminary drying until the moisture content of the papaya is 40% to 50%.
[0023] f. Sun-drying treatment: Place the pre-dried papaya in a sun-drying area and sun-dry it, controlling the ambient temperature and humidity to ensure that the papaya is dried until the moisture content does not exceed 15%.
[0024] g. Slicing: After cooling the dried papaya, slice it into 2mm thin slices;
[0025] h. Finished product packaging: The cut papaya slices are packaged and sealed to ensure drying effect and stable quality.
[0026] Preferably, the drying temperature of the blower oven is 70°C to 80°C, and the drying time is 30 to 60 minutes, until the papaya reaches the preset degree of dryness.
[0027] Preferably, the drying area includes an adjustable temperature-controlled drying platform equipped with temperature and humidity sensors to monitor environmental conditions in real time and automatically adjust the drying time and intensity based on sensor data to ensure uniform drying of the papaya.
[0028] Preferably, the training dataset includes cracks, brown spots, and insect damage, and data augmentation techniques are used during the training process to further improve the system's ability to recognize irregular shapes on the surface of papaya.
[0029] This invention provides an intelligent papaya processing system and method based on AI vision and a composite drying process. It has the following beneficial effects:
[0030] This intelligent papaya processing system and method, based on AI vision and a composite drying process, employs a deep learning model combined with a hybrid algorithm of convolutional neural networks and long short-term memory networks. By training on a dataset of papaya images containing different damage types and shapes, the system's ability to identify surface damage on papayas is significantly enhanced. This technology ensures the automatic screening of defective papayas during processing, preventing them from entering subsequent processes and thus improving processing accuracy and product quality.
[0031] The application of a composite drying process significantly improves the stability of papaya drying, especially in environments with excessively high humidity or low temperature. By combining the processes of a forced-air drying oven and a sun-drying area, the drying temperature and humidity conditions are rationally adjusted to ensure that the papayas are dried evenly to the required moisture content. Furthermore, the sun-drying area is equipped with an adjustable temperature-controlled drying platform and uses temperature and humidity sensors for real-time monitoring, making the papaya drying process more precise and avoiding uneven drying caused by environmental changes.
