Description

Technical Field

[0001] The utility model relates to a quick-freezing device for raw vegetables, belonging to the technical field of quick-freezing vegetables. Background Art

[0002] Vegetable quick freezing is a processing method for preserving vegetables by low-temperature quick freezing. As the temperature drops, the ice crystals increase in size, and the vegetables become hard and frozen. The pre-treated vegetables are quick-frozen at -30 to -35°C or lower, and then packaged in plastic bags, boxes and other containers, or quick-frozen after packaging, and then stored at -18°C to inhibit the growth and reproduction of microorganisms and the activity of enzymes, so that the vegetables can be preserved for a longer period of time.

[0003] The existing patent number CN218898166U is a quick-freezing device for raw vegetables. This device suspends vegetables through a hanging mechanism and places the vegetables separately to avoid the vegetables being stacked together, which is not conducive to the flow of cold air. By hanging, all parts of the vegetables can be fully exposed to the cold air, which can accelerate the freezing of the vegetables and avoid the phenomenon of uneven freezing of the vegetables in the box. The cold air is provided to the vegetables in the box by the cooling mechanism, but this device mainly performs internal quick-freezing processing through a fixed-stock box. This method can quickly freeze a single batch of vegetables, but cannot continuously quick-freeze the vegetables. When the box is opened and closed to put the vegetables in and out, a large amount of cold air will be lost, and repeated refrigeration is required, thereby increasing energy loss. In addition, the hanging method requires manual hanging of the vegetables, and the vegetables cannot be automatically clamped and dropped. Although the operation is simple, the large number of vegetables is relatively time-consuming, which reduces the convenience of hanging or removing the vegetables. Utility Model Content
