AI Technical Summary
During the low-temperature vacuum infusion of lotus seeds, it is difficult for the prior art to achieve uniform mixing of lotus seeds and pre-cooled liquid, resulting in uneven rapid freezing. In the contact between a large amount of pre-cooled liquid and lotus seeds, it is easy to generate bubbles, reducing the rapid freezing efficiency.
A low-temperature vacuum infusion mechanism is designed. By setting an arc plate, a turntable and a stirring rod in the low-temperature vacuum tank, the arc plate drives the lotus seeds to slowly transport to the top and then back to the bottom. The stirring rod stirs the pre-cooled liquid to ensure uniform mixing of the lotus seeds and the pre-cooled liquid, and reduces bubble generation by slowly outputting the pre-cooled liquid.
The uniform quick freezing of lotus seeds is achieved, the generation of bubbles is reduced, and the rapid freezing efficiency and quality of fresh lotus is improved.

Abstract

Technical Field
[0001] The utility model relates to the technical field of low-temperature vacuum filling mechanisms, in particular to a low-temperature vacuum filling mechanism for quick-frozen fresh lotus. Background Art
[0002] The water content of fresh lotus seeds after harvest is very high. They cannot be stored at room temperature, are easy to change color, and are easy to rot and deteriorate, which reduces the commodity value. The traditional drying process is not enough to maintain the original taste of fresh lotus seeds. The quick freezing processing technology can maintain the original quality characteristics of fresh lotus to the greatest extent, making it convenient to eat and extending the fresh storage period, which effectively promotes the development of lotus seed industrialization.
[0003] When performing low-altitude vacuum infusion of lotus seeds, the composite color retaining agent and the composite antifreeze agent are dissolved, filtered and mixed respectively to prepare an impregnation precooling liquid, which is then injected into a vacuum precooling tank after cooling, and then the pretreated fresh lotus is placed in the vacuum precooling tank to perform low-temperature vacuum infusion by impregnating the precooling liquid. A stirring structure is also required to make the lotus seeds and the precooling liquid mix more evenly, but the mixing structure is too simple, and the precooling liquid is mostly directly in contact with the lotus seeds at the bottom during input, and the lotus seeds at the top are also difficult to drop to the bottom during stirring and mixing, which easily leads to uneven quick freezing of the lotus seeds, and a large amount of precooling liquid directly in contact with the lotus seeds is likely to generate bubbles that affect the quick freezing quality of the lotus seeds, thereby reducing the quick freezing efficiency of the fresh lotus.
