Description

Technical Field

[0001] The present invention relates to the technical field of tangerine processing, and in particular to tangerine processing equipment and a method. Background Art

[0002] Chen tangerine peel is the dried mature peel of the citrus plant citrus and its cultivated varieties of the Rutaceae family. It needs to be naturally aged for at least three years, and specific varieties, such as tea-branch citrus and Xinhui citrus, are made in specific regions to be called tangerine peel. Ordinary citrus peel does not have the same medicinal effect without aging. It is often peeled into several petals, connected at the base, and some are irregular flakes. The outer surface is orange-red or reddish-brown, with fine wrinkles and concave dot-like oil chambers, and the inner surface is light yellow-white and rough, with yellow-white or yellow-brown tendon-like vascular bundles. It is slightly hard and brittle, fragrant, and tastes spicy and bitter. The core of tangerine peel lies in the word "chen". The smell and medicinal properties of tangerine peel are the result of years of aging. Only varieties with aging value can be called "tangerine peel". The aging value, simply put, is that the longer it is aged, the better: the longer it is stored, the more fragrant it is, and the better the effect.

[0003] For example, the patent document with the announcement number CN 112314905 A discloses a method for preparing aged oranges, comprising the following steps: taking whole citrus fruits, washing and removing impurities, steaming at high temperature and then drying at constant temperature, repeatedly steaming and drying 30-33 times, taking out and storing in a cool and dry place, and naturally fermenting for at least 30 days to obtain aged oranges. The preparation method of the present invention can be used for aging whole citrus fruits, and can effectively prevent the whole citrus fruits from becoming moldy during the aging process. The preparation method is simple, the degree of preparation is controllable, the production efficiency is high, and the aging quality of aged oranges can be effectively improved. The obtained aged oranges have complete fruit shape, are dark brown inside and outside, have light specific gravity, hard orange peel, clear surface texture, mellow citrus aroma, and high content of effective ingredients.

[0004] The traditional processing method of aged oranges mainly focuses on steps such as fermentation and drying to form a unique flavor and aroma. As consumers' requirements for food quality and uniqueness continue to increase, it is particularly important to explore new processing methods to give aged oranges more diversified flavors and quality characteristics. Among them, the frosting method can increase the processing flavor of aged oranges in a natural way. However, when processing aged oranges, the existing structure can only achieve a simple overall sealed fermentation operation due to its own structural limitations. After the subsequent fermentation is completed, the internal aged oranges cannot be quickly removed and spread, and efficient winter frosting and drying operations cannot be performed during the aged orange processing process. At the same time, the equipment cannot perform faster disassembly, cleaning and maintenance operations inside the container, and cannot meet daily use needs. Therefore, it is urgent to design an aged orange processing equipment and method to solve the above problems. Summary of the Invention

Then, the fermentation inner tank can be quickly unscrewed from the connecting thread on the inner wall of the positioning seat. After the fermentation inner tank is docked to the interior of the protective outer tank, the air control pump can be started appropriately to inflate from the second air control valve seat of the protective outer tank, so that the top fixed airbags at the annular shrinkage groove and the vertical shrinkage groove on the inner wall of the protective outer tank are evenly inflated and pressed inward. At the same time, the positioning seat can be adaptively docked at the positioning cover at the bottom end of the protective outer tank, and the air control pump is started again to inflate from the first air control valve seat of the positioning cover. Then, the plug-in airbags inside the shrinkage cover can be adaptively plugged into the positioning slots on the four sides of the positioning seat through the uniform air side cover.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The aged orange processing equipment and method can enable the equipment to perform fermentation, frosting and air-drying that is more suitable for aged orange processing, and complete auxiliary operations for efficient aged orange processing. In actual use, the staff first puts the peel raw materials for aged orange processing into the inside of the side shield, and then inserts them into the inside of the protective outer tank through the top cover. The aged oranges are fermented inside the protective outer tank with yeast and probiotics. The subsequently unfolded side shield can ensure stable ventilation during natural frosting and air-drying, which is more suitable for aged orange processing operations. In summary, the aged orange processing operations are preliminarily completed after three years of fermentation. Natural frosting, as a method of processing fruits using natural environmental conditions, can bring new flavors and quality changes to aged oranges. By combining processes such as fermentation, natural frosting and long-term air-drying, the aged orange products are given a unique taste and flavor, while improving the quality and nutritional value of the products, further enhancing the taste of the aged oranges, and reflecting the practicality of the equipment design.

[0022] The aging orange processing equipment and method further improve the overall use effect of the equipment.

At the same time, the positioning seat can be adaptably connected to the positioning cover at the bottom of the protective outer tank. The air control pump is started again to perform an inflation operation from the first air control valve seat of the positioning cover. Then, the plug-in air bags inside the shrinkage cover can be adaptably connected to the positioning slots on the four sides of the positioning seat through the uniform air side cover for locking operation, thereby ensuring the stability of the fermentation liner in daily fermentation use.

The second air control valve seat (22) is used for inflation operation, so that the top fixed air bag (28) at the annular shrinkage groove (26) and the vertical shrinkage groove (27) on the inner wall of the protective outer tank (1) is uniformly inflated and pressed inward. At the same time, the positioning seat (12) can be adapted to be docked at the positioning cover (9) at the bottom end of the protective outer tank (1). The air control pump (10) is started again to perform inflation operation from the first air control valve seat (21) of the positioning cover (9). Then, the plug-in air bag (25) inside the shrinkage cover (24) can be adapted to be plugged into the positioning slots (18) on the four sides of the positioning seat (12) through the uniform air side cover (23).
