Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable processing technology, and specifically relates to a passion fruit washing and drying device. Background Technology

[0002] Passion fruit, a tropical fruit rich in vitamins, dietary fiber, and various minerals, has seen increasingly widespread application in food processing and beverage production in recent years due to its unique flavor and rich nutritional value, leading to a continuous rise in market demand. With the advancement of industrialized and large-scale passion fruit cultivation, the efficiency and quality control of its post-harvest processing have become key factors restricting the industry's development. Among these processes, washing and drying are the core steps in post-harvest processing, directly affecting product safety, shelf life, and subsequent processing quality. Residual soil, pesticide residues, dust, and other impurities on the surface can lead to microbial growth during processing, while residual moisture after washing can easily cause fruit rot and spoilage, resulting in serious economic losses.

[0003] Existing passion fruit cleaning equipment mainly relies on single spray cleaning or soaking cleaning. Spray cleaning devices use high-pressure water jets to wash the fruit surface, but due to the irregular shape and textured surface of passion fruit, the fruit tends to pile up and overlap in traditional conveyor systems, resulting in some areas not being covered by the water flow, creating cleaning dead spots, and making it difficult to thoroughly remove pesticide residues and stubborn stains. Immersion cleaning, while achieving all-round contact, can easily damage the fruit skin if soaked for too long, and the wastewater is prone to secondary pollution, limiting the cleaning effect. At the same time, most cleaning devices lack a pre-washing stage, directly sending passion fruit with mud and dirt into the spraying process, which not only increases the workload of the spraying system but also reduces cleaning efficiency, making it difficult to meet the needs of batch processing.

[0004] In the drying stage, existing equipment mostly uses single blower air drying or hot air drying. Due to the lack of an effective material unloading mechanism, the washed passion fruit remains stacked during the conveying process, with narrow gaps between the fruit, making it difficult for airflow to penetrate, resulting in uneven drying and significant moisture residue on the surface of some fruit. In addition, although hot air drying is faster, the high temperature can easily damage the nutrients and flavor compounds on the passion fruit peel, affecting product quality; while air drying with ordinary blowers requires a longer drying time due to uneven airflow distribution, reducing overall processing efficiency.

[0005] With consumers' increasing demands for food safety and quality, and the industry's urgent need for processing efficiency and cost control, the shortcomings of existing passion fruit washing and drying equipment in terms of thorough cleaning, uniform drying, smooth process transitions, and space utilization are becoming increasingly apparent. Therefore, developing a passion fruit washing and drying device that can achieve graded cleaning, efficient material distribution, uniform drying, automated processes, and a compact structure has become an urgent need for the current industry development.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This invention provides a passion fruit washing and drying device, which aims to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A passion fruit washing and drying device includes a conveying mechanism and a spraying mechanism. The spraying mechanism is located above the conveying mechanism. A conveyor belt is connected to the rear end of the conveying mechanism. A material unloading mechanism and a drying mechanism are provided on the conveyor belt. The material unloading mechanism is located in front of the drying mechanism.

[0010] The unloading mechanism includes two sets of unloading components arranged one behind the other. Each unloading component includes a rotating shaft and multiple unloading rods spaced apart from the rotating shaft. The rotating shaft is rotatably connected to the conveyor belt via a base.

[0011] The end of the feeding rod away from the rotating shaft is bent and abuts against a surface of the conveyor belt, and a feeding channel is formed between two adjacent feeding rods.

[0012] Preferably, a locking block is provided on the rotating shaft of one of the front feeding components, the locking block having a recessed locking groove, and a limiting groove being recessed on the inner sidewall of the locking groove; a limiting component is provided on the feeding rod of one of the rear feeding components.

[0013] When one of the material feeding components located in front rotates and is placed on the material feeding component located behind, the material feeding rod of the material feeding component located behind is connected to the limiting groove through the limiting component.

[0014] Preferably, the limiting assembly includes a spring and a ball, the unloading rod has a receiving cavity, the spring is disposed in the receiving cavity and connected to the ball.

[0015] When the feed rod is engaged in the slot, the ball is connected to the limiting groove.

[0016] Preferably, the drying mechanism includes multiple blowers spaced apart on the conveyor belt.

[0018] Preferably, a feeding mechanism is provided at the front end of the conveying mechanism. The feeding mechanism includes a storage tank and a hoist. The hoist is located in the storage tank and its output end points to the conveying mechanism.

[0019] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model provides a passion fruit washing and drying device with a simple structure and lightweight design. It adopts a graded washing design with a material storage tank for pre-washing and deep spray washing. The material storage tank first removes floating dirt from the surface of the fruit, reducing the workload of the spraying mechanism. The subsequent high-pressure spray can specifically remove stubborn impurities and pesticide residues, avoiding the cleaning dead corners caused by a single washing method, greatly improving the cleanliness of the fruit and ensuring product safety.

[0021] 2. This utility model sets up two sets of feeding components, which facilitate the even distribution of fruits on the conveyor belt. With the help of multiple blowers arranged at intervals, the airflow can fully penetrate the gaps between the fruits, avoiding local moisture residue or fruits missing the drying process, thus improving drying efficiency. Moreover, room temperature air drying will not damage the nutritional components and flavor of the fruits.

[0022] 3. The material feeding mechanism of this utility model is equipped with a locking block and a spring ball forming a limiting component that cooperate with each other. When idle, the front material feeding component can be rotated and locked onto the rear material feeding component. At the same time, the locking block and the spring ball form a limiting component that cooperate with each other to realize the quick storage of the rear material feeding component. Compared with the traditional fixed material feeding structure, it reduces the equipment space occupation rate and facilitates workshop layout and equipment maintenance. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figures 1 to 3 As shown, a passion fruit washing and drying device includes a conveying mechanism 1 and a spraying mechanism 2. The spraying mechanism 2 is located above the conveying mechanism 1. The rear end of the conveying mechanism 1 abuts against a conveyor belt 3. The conveyor belt 3 is equipped with a material unloading mechanism 4 and a drying mechanism 5. The material unloading mechanism 4 is located in front of the drying mechanism 5. The material unloading mechanism 4 includes two sets of material unloading components 41 arranged one after the other. The material unloading component 41 includes a rotating shaft 411 and a plurality of material unloading rods 412 spaced apart from the rotating shaft 411. The rotating shaft 411 is rotatably connected to the conveyor belt 3 through a base 100. The end of the material unloading rod 412 away from the rotating shaft 411 is bent and abuts against the surface of the conveyor belt 3. A material unloading channel 200 is formed between two adjacent material unloading rods 412.

[0031] This invention features a material distribution mechanism 4 on the conveyor belt 3, which facilitates the even distribution of fruits on the conveyor belt 3. Combined with the drying mechanism 5, this allows airflow to fully penetrate the gaps between the fruits, preventing localized moisture residue or fruits from missing the drying process, thus improving drying efficiency. Furthermore, room temperature air drying does not damage the nutritional components and flavor of the fruits.

[0032] In this embodiment, please refer to Figure 2 A locking block 6 is provided on the rotating shaft 411 of the front material feeding assembly 41. The locking block 6 has a recessed locking groove 61. A limiting groove 611 is recessed on the inner side wall of the locking groove 61. A limiting component 7 is provided on the material feeding rod 412 of the rear material feeding assembly 41. When the front material feeding assembly 41 rotates and is placed on the rear material feeding assembly 41, the material feeding rod 412 of the rear material feeding assembly 41 is connected to the limiting groove 611 through the limiting component 7.

[0033] The two sets of material unloading components 41, arranged one in front of the other, can be folded together using the locking block 6 and the limiting component 7 to achieve quick storage. Compared with the traditional fixed material unloading structure, this reduces the space occupied by the equipment and facilitates workshop layout and equipment maintenance. Specifically, one end of the rotating shaft 411 of the front material unloading component 41 is provided with a wheel (not shown in the figure), which allows manual rotation of the wheel to rotate the front material unloading component 41 and place it on the rear material unloading component 41.

[0034] For details, please refer to Figure 3 The limiting component 7 includes a spring 71 and a ball 72. A receiving cavity 4121 is provided on the unloading rod 412. The spring 71 is located within the receiving cavity 4121 and connected to the ball 72. When the unloading rod 412 is engaged in the locking groove 61, the ball 72 engages with the limiting groove 611. Specifically, the spring 71 and the ball 72 work together, utilizing the elastic properties of the spring 71 to allow the ball 72 to elastically connect with the limiting groove 611, facilitating disengagement from the unloading rod and locking block during operation, making operation simple and convenient.

[0035] In this embodiment, the drying mechanism 5 includes multiple blowers 51 spaced apart on the first conveyor belt 3; the end of the first conveyor belt 3 is connected to a second conveyor belt 8 arranged perpendicularly to it; the arrangement of the second conveyor belt 8 facilitates the transfer of the washed and dried passion fruit to the next process, thereby achieving smooth transfer between different processes and adapting to the production line layout.

[0036] In this embodiment, please refer to the return. Figure 1 A feeding mechanism 9 is located at the front end of the conveying mechanism 1. The feeding mechanism 9 includes a storage tank 91 and an elevator 92. The elevator 92 is located inside the storage tank 91, and its output end points towards the conveying mechanism 1. A graded cleaning design is adopted, consisting of pre-washing in the storage tank 91 and deep washing by spraying. The storage tank 91 first removes surface dirt from the fruit, reducing the workload of the spraying mechanism 2. Subsequent high-pressure spraying can specifically remove stubborn impurities and pesticide residues, avoiding cleaning dead zones caused by a single cleaning method, significantly improving fruit cleanliness, and ensuring product safety.

[0037] Furthermore, both the conveying mechanism 1 and the spraying mechanism 2 of this utility model are conventional technical means, and will not be described in detail in this example. The conveying mechanism 1 includes a conveying trough and multiple brush rollers rotatably connected at intervals within the conveying trough. The passion fruit is conveyed and introduced into the trough by the rotation of the brush rollers, and the spraying mechanism 2 is used to clean it, so as to achieve the purpose of thoroughly cleaning and removing dirt from the passion fruit.

[0038] The working principle of this utility model:

[0039] This utility model provides a passion fruit washing and drying device. In specific use, clean water is injected into the storage tank 91, and the harvested passion fruit is put into the storage tank 91. The floating dirt is pre-washed by soaking in water. Then, the elevator 92 is started. The elevator 92 picks up the pre-washed passion fruit from the storage tank and transports it to the input end of the conveying mechanism 1 to complete the automated feeding.

[0040] After the conveyor mechanism 1 is started, it drives the passion fruit to move at a constant speed. At the same time, the spraying mechanism 2 is turned on. The spraying mechanism 2 sprays high-pressure water jets onto the moving passion fruit to thoroughly wash away stubborn stains and pesticide residues on the surface of the fruit, achieving deep cleaning. The wastewater after cleaning is discharged through the gaps in the conveyor mechanism.

[0041] After being washed, the passion fruit is transferred to conveyor belt 3 by conveyor mechanism 1. At this time, two sets of unloading components 41 are used to unload the piled passion fruit one by one into each unloading channel 200 to ensure that the fruit is evenly distributed. Then, multiple blowers 51 set at intervals are turned on, and the airflow blows vertically onto the passion fruit on conveyor belt 3 to quickly remove the residual moisture on the surface of the fruit, achieve uniform drying, and the unloaded fruit is unobstructed, which improves the drying efficiency.

[0042] After drying, the passion fruit moves to the end of the conveyor belt 3 and is then transferred to subsequent processing steps, such as sorting or packaging, by the vertically set conveyor belt 8 to complete the entire cleaning and drying process.

[0043] When the equipment is idle, manually rotate the front unloading assembly 41 so that it is placed on the rear unloading assembly 41. At this time, the ball 72 on the rear unloading rod 412 is inserted into the limiting groove 611 of the front locking block 6 under the elastic force of the spring 71, so as to realize the storage and fixation of the unloading mechanism 4 and save storage space.

[0044] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
