Description

Technical Field

[0001] The invention belongs to the field of fruit processing, and particularly relates to an automated unit for shape-preserving processing of pomegranate particles. Background Art

[0002] Pomegranates, a specialty fruit with both nutritional and economic value, enjoy a wide consumer market worldwide. Pomegranate varieties are primarily categorized into two types: soft-seeded and hard-seeded. These two types differ significantly in taste, flavor, and applicable scenarios.

[0003] Soft-seeded pomegranates, with their small, soft seeds, high sugar content, and abundant juice, have become a mainstream choice in the fresh food market and are highly favored by consumers. In contrast, hard-seeded pomegranates, with their large, hard seeds, a slightly sour taste with a distinct astringency, and some shriveled, less juicy flesh, are more suitable for processing into various products, such as pomegranate juice, pomegranate jam, and pomegranate wine, to enhance their value.

[0004] Currently, the industry primarily uses two methods for peeling soft-seeded pomegranates: Semi-automatic equipment is used. Because soft-seeded pomegranates are small and soft, they are easily damaged by mechanical compression and friction during operation. This results in a low rate of intact pomegranates, severely impacting product appearance and value, and making it difficult to meet market demand for high-quality fresh pomegranate cups. Manual peeling is also used. While manual operation can ensure pomegranate integrity to a certain extent, it has significant drawbacks. First, labor costs are high, especially during peak soft-seeded pomegranate season, when labor demand surges, further driving up production costs. Second, manual operation makes it difficult to achieve standardized hygiene controls and is easily affected by environmental factors, operator habits, and other factors. This poses a risk of microbial contamination and fails to meet stringent food safety requirements. Summary of the Invention

In this embodiment, the pomegranate fruit particle anti-damage purification machine C can be implemented with reference to existing equipment.

[0056] See also Figures 1-19 The working principle of the automated unit for shape-preserving processing of pomegranate fruit particles of the present invention is as follows:

[0057] During operation, pomegranates are placed in the pomegranate cleaning and feeding machine A, and the pomegranates are cleaned by the pomegranate cleaning device. The cleaned pomegranates are transported to the pomegranate fruit non-destructive separator B through the pomegranate feeding and conveying device 20.

[0058] In the pomegranate fruit non-destructive separator B, the pomegranate feeding and conveying device 20 conveys the pomegranate into the "petal opening bin" formed by two groups of petal opening clamps 4, and is blocked by the baffle plate 6 so that the pomegranate stays in the "petal opening bin". The pomegranate in the "petal opening bin" is gradually in a central position under the guidance of the receiving spring piece 5; then the pressing plate 9 in the pressing mechanism moves downward and presses on the pomegranate to prompt the pomegranate to move downward, and the elastic connecting piece rotates outward to expose the cutter and insert it into the pomegranate, and then the petal opening drive mechanism 8 drives the two groups of petal opening clamps 4 to move in the opposite direction, thereby tearing the pomegranate open. During this process, the pressing mechanism continuously outputs pressure on the pomegranate; when the torn pomegranate is The pomegranate falls onto the pomegranate conveyor line below, and the pomegranate that is about to open is transferred to the conveyor network chain 13, so that the skin of the pomegranate faces upward and the opening faces downward; it is then transported to the beating station by the conveyor network chain 13, and the beating drive mechanism drives the beating plate 1401 to swing up and down, thereby beating the skin of the pomegranate. The beating action will cause the pomegranate particles to fall from the pomegranate skin and pass through the mesh in the conveyor network chain 13 into the collecting device. The guide plates 16 on both sides of the collecting trough 17 in the collecting device will guide the pomegranate particles to slide into the collecting trough 17, so as to achieve lossless separation and collection of the pomegranate particles; the pomegranate peel after separation of the pomegranate particles is transported to the peel collecting device 8.

[0059] Since the separated pomegranate particles are still mixed with impurities such as peel and diaphragm, the separated pomegranate particles need to be transported to the pomegranate particle anti-damage purification machine C for purification; the pomegranate particle anti-damage purification machine C is used to vibrate and separate the pomegranate particles, so that the pomegranate particles with a particle size smaller than the screen fall into the corresponding collection module below, while the pomegranate particles remain on the screen and are collected by the corresponding collection module.

[0060] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content.
