Description

Technical Field

[0001] The utility model belongs to the technical field of fruit and vegetable processing, and particularly relates to a fruit and vegetable cleaning and drying device. Background Art

[0002] Fruits and vegetables are not only rich in essential nutrients, but also contribute to digestive health with their unique flavor. However, during the cultivation process, pesticides and fertilizers are inevitably used to control pests and diseases. These chemicals, along with naturally occurring pathogens, often remain on the rough or uneven surfaces of fruits and vegetables, posing a potential health hazard. If not thoroughly cleaned, residual pesticides, pathogens, and fertilizers can easily cause diarrhea, abdominal pain, or even more serious pesticide poisoning. Proper cleaning of fruits and vegetables is crucial to protecting consumer health.

[0003] We generally rinse fruits and vegetables continuously with running tap water. Running water can effectively wash away most surface dirt and reduce the risk of pesticides seeping into the fruit. However, if moisture remains on the surface of washed fruits and vegetables and they are not eaten for a long time, bacteria will grow, leading to secondary contamination of the fruits and vegetables, affecting their cleanliness and safety.

[0004] Therefore, it is urgent to develop a fruit washing and drying device that integrates cleaning and drying. Utility Model Content

At the same time, a temperature sensor is installed on the top of the oven to monitor and feedback the temperature changes inside the oven in real time, and convert it into accurate data and feed it back to the intelligent controller. The intelligent controller flexibly adjusts the temperature in the drying box according to the feedback information, which can not only quickly remove the moisture on the surface of fruits and vegetables, but also quickly and accurately set the most suitable temperature environment according to different types of fruits and vegetables and their drying requirements, while ensuring the nutrition and taste of fruits and vegetables, achieving energy-saving and high-efficiency effects.

[0017] (2) The utility model constructs a seamless process from washing to drying by using the coordination between the cylinder, piston rod, storage basket, hot air system components, ultrasonic vibrator and other structures. The cylinder acts as a power source to drive the piston rod to move up and down, so that the storage basket can be freely raised and lowered, so that the washed fruits and vegetables can be directly moved from the washing room to the drying room without manual transfer; and during the washing stage, the ultrasonic vibrator can produce a strong cavitation effect, penetrate into the tiny gaps of the fruits and vegetables, and completely remove the attached dirt and pesticide residues; this process not only saves a lot of manpower and time, but also effectively avoids the secondary contamination that the fruits and vegetables may suffer during the transfer process, and not only realizes the automation and continuous operation of fruits and vegetables from washing to drying, but also greatly improves the hygiene standards and product quality during the processing process.

[0031] Working Principle: When in use, first turn on the power, then open the door 10 on the front of the drying chamber 2. The intelligent controller 71 activates the cylinder 72, which drives the piston rod 73 to steadily raise the storage basket 75 to the vicinity of the door 10. The fruits and vegetables to be cleaned are placed into the storage basket 75. The cylinder 71 then reverses and steadily delivers the storage basket 75 containing the fruits and vegetables into the washing chamber 3. Subsequently, the intelligent controller 71 activates the water pump 5, which pumps water from the water tank 4 through the first water supply pipe 41 and delivers it to the water collection tank 31 through the second water supply pipe 51. The water in the water collection tank 31 is sprayed by the water spray head 32 onto the fruits and vegetables in the storage basket 75. Simultaneously, the ultrasonic vibrator 76 is activated, utilizing the ultrasonic vibration effect to enhance the cleaning effect and ensure that the surfaces of the fruits and vegetables are fully cleaned. Throughout the cleaning process, liquid level sensor 28 monitors the water level in cleaning chamber 3 in real time and promptly feeds this data back to intelligent controller 71, allowing any water exceeding the set level to be promptly discharged through outlet pipe 33 into wastewater collection tank 6. When the fruits and vegetables are cleaned, cylinder 72 is activated again, and piston rod 73 pushes basket 75 containing the cleaned fruits and vegetables smoothly upward into drying chamber 2. Centrifugal fan 11 is then activated, drawing air in through the air inlet (equipped with an air filter) provided on upper accessory housing 1. After being heated by heater 14, air is then delivered to drying chamber 2 via second air duct 13, where it is delivered through outlets on the top and sides, ensuring comprehensive and even drying of the fruits and vegetables.
