Technical Field

[0001] This invention belongs to the field of vegetable processing technology, and in particular relates to a processing device and processing technology for fresh-cut vegetables. Background Technology

[0002] Fresh-cut vegetables, also known as minimally processed vegetables, are ready-to-eat or ready-to-use vegetable products that have undergone a series of processes such as grading, sorting, cutting, washing, and packaging, and are intended for direct consumption or cooking by consumers. With the accelerating pace of life and the rapid development of the catering industry, the market demand for fresh-cut vegetables is growing daily.

[0003] Existing fresh-cut vegetable processing equipment typically includes conveying, cutting, washing, and packaging processes. However, in actual production, these existing systems have the following shortcomings: First, vegetable juices and debris easily remain on the cutting blades after cutting. If not cleaned promptly, this not only affects the hygiene of subsequent cutting processes, leading to cross-contamination, but also fosters bacterial growth and shortens the product's shelf life. Second, existing cutting devices can only perform simple cuts and cannot guarantee consistent cutting. Furthermore, vegetables need to be washed after cutting to remove impurities and cell sap, but after washing, they usually need to be transferred to specialized draining equipment for drying. This lack of seamless process integration affects processing efficiency.

[0022] In one embodiment of the invention, a clamping member is used to secure the vegetables during cutting, and a cleaning member is used to automatically rinse the cut vegetables after cutting. The cleaning assembly includes a cleaning tank and integrated cleaning and draining members thereon, used for cleaning and draining the cut vegetables, respectively. A packaging assembly is used to package the drained vegetables.

[0023] As an optional implementation, the cutting component includes a fixed frame 5 fixedly connected to the bracket 2. A support plate 7 is slidably connected to the fixed frame 5 via an electric telescopic rod 6. Vertical plates 8 are fixedly connected to both sides of the bottom end of the support plate 7.

After the vegetables stop being conveyed on the second conveyor belt 3, the electric telescopic rod 6 drives the support plate 7 to descend. The clamping plate 12 in the clamping member clamps and fixes the vegetables under air pressure. Then, the support plate 7 continues to descend, and the cutting blade 9 cuts the vegetables. After cutting, the electric telescopic rod 6 drives the support plate 7 to rise and reset, the clamping plate 12 is released, and at the same time, the flushing nozzle 21 is activated to perform high-pressure flushing on the cutting blade 9 to remove residual vegetable debris. The cut vegetables are sent to the washing tank 4 by the second conveyor belt 3, and the aeration pipe 22 and the spray pipe 23 simultaneously wash the vegetables. After washing, the vegetables are collected in two draining nets 30, the motor 31 is activated, and the support tank 27 is rotated to drain the vegetables. During this process, the rotation can be used to accelerate the draining process. After being drained, the vegetables enter the packaging component 32 and are packaged by the bagging module. At the same time, the gas replacement module fills the packaging bag with a mixture of nitrogen, carbon dioxide and oxygen to complete the processing of fresh-cut vegetables.
