Abstract
Description
Technical Field
[0001] This invention relates to a fruit wine production equipment, specifically a production equipment for processing and brewing dragon fruit, a plant belonging to the cactus family and the genus Hylocereus. Background Technology
[0002] Currently, common fruit wines made from fruit include grape wine, apple wine, mulberry wine, bayberry wine, lychee wine, and kumquat wine. These are mainly produced by juicing fruits with high sugar content and short shelf life, then adding appropriate amounts of fermentation bacteria for fermentation. These fruit wines are nutritious, have low alcohol content, and are suitable for the general public, while also solving the problem of high yields but short shelf lives in fruit-producing regions. However, current reports generally focus on the production equipment for grape wine, apple wine, and mulberry wine, which mainly involves pulping, fermentation, aging, and filtration.
[0003] Dragon fruit (Latin name: Hylocereus undulatus Britt.), also known as fire dragon fruit, dragon pearl fruit, fairy honey fruit, and jade dragon fruit, is an oval-shaped fruit, 10-12 cm in diameter, with a red or yellow exterior, green triangular leaf-like structures, white, red, or yellow flesh, and black sesame-seed-like seeds. In recent years, dragon fruit production has been high, and the high-quality red-fleshed variety, the pitaya (dragon fruit), has begun to be widely cultivated. Pitaya is sweet, juicy, highly nutritious, and delicious. It is rich in vitamins and trace elements, possesses strong antioxidant capabilities, and can eliminate free radicals. Moderate consumption is beneficial to the cardiovascular and digestive systems. However, due to its soft flesh, short shelf life, and difficulty in transportation, it easily rots if the skin is damaged, leading to waste. Making it into fruit wine could significantly increase its added value and promote the comprehensive utilization of pitaya. Therefore, some regions have experimented with and produced pitaya wine. However, due to insufficient research on its production process and equipment, the methods are often limited to simply pulping the fruit and adding yeast in fermentation tanks. The lack of sophisticated equipment has resulted in many high-yield pitaya crops rotting in the fields, leaving farmers with no income from their hard-earned produce.
[0004] The following are publicly available literature reports on dragon fruit wine: I. Chinese Patent: Patent Application No. CN 202110123119.8, Application Date 2021-01-29, Title: "A Preparation Process of Red Dragon Fruit Wine", Applicant: Guangxi Zhuang Autonomous Region Academy of Agricultural Sciences, Inventors: Liu Guoming, He Xuemei, Li Jiemin, Ye Dongqing, Tang Yayuan, Yi Ping, Ling Dongning, Wei Ping, Li Li, Sun Jian; Publication No. CN112680305A; Publication Date: April 20, 2021; However, this invention only discloses the preparation process of red dragon fruit wine: (1) preparation of dragon fruit pulp, (2) fermentation, (3) addition of ingredients, (4) aging and (5) membrane filtration. However, it does not disclose what equipment is used, nor does it propose existing production equipment for red dragon fruit wine.
[0005] Furthermore, those skilled in the art know that dragon fruit requires regular pruning during cultivation to promote better flowering and fruiting, thereby increasing yield. Especially in late autumn after harvesting the current year's fruit, pruning becomes a crucial step for the branches to regrow the following spring. A large number of irregularly growing dragon fruit branches need to be pruned. These discarded branches are difficult to dispose of when piled up at the edge of the field, as they rot and pollute the environment. Even if the branches are brought back, they are of little use, as they have thorns and are unsuitable as feed for cattle and sheep. The same applies to the peels removed during dragon fruit processing; they are more prone to rotting, spoiling, and becoming smelly when left in the environment. It is a waste of resources not to utilize the discarded dragon fruit branches and peels. Summary of the Invention
[0006] The objectives of this invention are: 1. To address the challenges of soft, easily damaged, and short-shelf-life dragon fruit, by designing a dragon fruit wine production system to produce a nutritious, brightly colored, delicious, long-lasting, and high-quality fruit wine to meet market demand. 2. To solve the environmental pollution problems caused by the current practice of piling up discarded dragon fruit branches after autumn pruning and the discarded peels after dragon fruit processing. This system will recycle and reuse dragon fruit branches and peels, replacing water added during fermentation and extracting juice to obtain nutritionally complete raw materials for use in fruit wine production and as a palatable beverage. 3. By utilizing the properties and characteristics of dragon fruit seeds, all raw materials after fruit wine filtration can be fully utilized, achieving a completely closed-loop dragon fruit wine production process with zero wastewater and waste residue discharge.

A production equipment for dragon fruit wine, comprising: a dragon fruit peeling machine, a pulping machine, a dragon fruit branch dethorning machine, a branch and peel juicer, a fermentation tank, a fruit wine aging barrel, and a grinder; the production of the dragon fruit wine involves peeling the dragon fruit with the peeling machine, pulping the pulp with the pulping machine, then combining it with the juice extracted by the dragon fruit branch and peel juicer in the fermentation tank, adding yeast for fermentation, filtering out the fruit wine residue through a filter, and then aging the fruit wine in a wooden barrel, sterilizing it with a sterilizer, and finally packaging it with a packaging machine to obtain the dragon fruit wine.
[0008] The above-mentioned fruit wine fermentation tank is equipped with a filter at the outlet. After the fruit wine residue is filtered, it enters a grinder to grind dragon fruit seeds into particles the size of sesame seeds. Dragon fruit seeds contain a large amount of fats and proteins that are beneficial to the human body. Then, they are stored in a storage tank for later use as raw materials for the production of dragon fruit health drinks.
[0009] The fermentation tanks mentioned above are made of earthenware because earthenware tanks do not contain metal ions like metal tanks, resulting in a mellow and flavorful fruit wine.
[0010] The aforementioned dragon fruit branch dethorn removal machine is designed based on the triangular prism shape of dragon fruit branches. It includes a dragon fruit branch support plate, a front guide block, a blade mounting body, a rear guide block, a dethorn removal branch outlet guide plate, and a burr collection bin. The dragon fruit branch support plate is installed in front of the front guide block, and the blade mounting body is installed between the front and rear guide blocks. The rear guide block outlet is equipped with a dethorn removal branch outlet guide plate and a burr residue collection box. The dragon fruit branch enters the front guide block and blade mounting body from the dragon fruit branch support plate to remove the burrs on the branch. Then, it is guided by the rear guide block to the dethorn removal branch guide plate and enters the dragon fruit branch and peel press to extract juice. The burr residue falls into the burr collection box.
[0011] The dragon fruit branch thorn removal machine can be installed on the panel of the frame. The frame has a universal wheel mounting bracket at the bottom and universal wheels at the bottom, which can be moved easily.
[0012] The aforementioned blade mount is installed on the panel by screws. The blade mount has three triangular blades and three blade adjusters, corresponding to the triangular prism of the dragon fruit branch. The blade mount has a triangular through hole in the middle for the branch. When the branch passes through the triangular through hole, the burrs on the side of the branch are cut off by the three blades. A spring is provided above the three blades, so that branches of different sizes can cut the burrs of the branch through the extension and retraction of the blades and the spring.
[0013] The dragon fruit branch inlet tray is equipped with a pushing mechanism or robot arm on both sides to straighten the branch into the front guide block and pass through the triangular through hole in the middle of the blade mounting body to remove the burrs on the edge of the branch.
[0014] The aforementioned front guide block and rear guide block can also be designed as an automatic transmission device, which automates the removal of burrs from the branches by the blade. Attached Figure Description

The dragon fruit wine production equipment designed in this invention solves the problems of soft, easily damaged, and short shelf life of dragon fruit pulp. The designed dragon fruit wine production equipment produces a fruit wine that is nutritious, brightly colored, tastes good, has a long shelf life, and is of high quality. This dragon fruit wine is rich in vitamins, polysaccharides, betaine, amino acids, and various trace elements, making it a fruit wine with abundant nutritional components.
[0017] Second, to solve the current problems of environmental pollution caused by the piles of discarded dragon fruit branches pruned in autumn and the environmental pollution caused by the piles of discarded fruit peels after dragon fruit processing, the dragon fruit branches and peels can be recycled and reused. They can also replace the water added during the fermentation process and be juiced to obtain nutritionally complete raw materials that can be used as raw materials in the production of fruit wine and delicious beverages.
[0018] Third, because the fermented mash filtered from dragon fruit contains a large number of sesame-like seeds, these dragon fruit seeds have high-quality oils and proteins, and have antioxidant activity, promote digestion, improve constipation, lower blood sugar, regulate blood lipids, detoxify, and prevent anemia. According to the 2025 compositional analysis of dragon fruit seeds by the Guangxi Academy of Sciences, its fat content is the highest at 28.34%, followed by protein at 25.06%. Other components include starch at 17.05%, total sugar at 1.75%, crude fiber at 13.33%, and ash at 3.18%. Essential fatty acids account for about 50% of the fatty acids in dragon fruit seed oil, with unsaturated fatty acids accounting for as high as 78.22%, including linoleic acid at 51.25%, flavonoids at 3.05%, and squalene at 5.24%. These are rare bioactive components in plant oils, classifying it as a high-quality edible oil. Dragon fruit seed protein contains a complete range of amino acids, including abundant omega-3 fatty acids. The content of essential amino acids is greater than 20%. Specific effects and functions include: ① Antioxidant activity: Dragon fruit seeds are rich in anthocyanins and other antioxidants, which can scavenge free radicals, helping to delay aging, prevent arteriosclerosis and heart disease, prevent Alzheimer's disease, and also prevent healthy cells from becoming cancerous. ② Promotes digestion: The dietary fiber in dragon fruit seeds can increase intestinal peristalsis and improve the gastrointestinal environment, thereby promoting digestion. ③ Improves constipation: Dragon fruit seeds are rich in water-soluble dietary fiber, which can absorb water and swell, stimulating the intestinal wall and softening stool, thus relieving constipation. ④ Lowers blood sugar: Certain components in dragon fruit seeds have an auxiliary effect in lowering blood sugar, which can help control blood sugar levels in diabetic patients. ⑤ Regulates blood lipids: The unsaturated fatty acids in dragon fruit seeds can lower the level of low-density lipoprotein cholesterol and increase the proportion of high-density lipoprotein cholesterol, thereby regulating blood lipids. ⑥ Detoxifies: Dragon fruit seeds contain a plant-based albumin that can improve the beneficial flora in the gut, remove heavy metals from the body, protect the gastric mucosa, and play a detoxifying role. ⑦ Prevents anemia: Dragon fruit seeds are high in iron, which can enhance hemoglobin production and prevent anemia. ⑧ It contains abundant Omega-3, an important component of the brain and retina. It can improve memory, attention and reaction speed in adults, relieve brain fatigue, and prevent neurological diseases such as Alzheimer's disease. Utilizing dragon fruit seeds to make health drinks can also achieve a completely closed-loop production process for dragon fruit wine with no wastewater or waste residue discharge. Detailed Implementation
[0019] Example 1 (Equipment and Process Introduction) A dragon fruit wine production equipment includes a dragon fruit peeling machine 1, a pulping machine 2, a dragon fruit branch dethorning machine 5, a branch and peel juicer 6, a fermentation tank 8, a fruit wine aging barrel 10, and a grinder 12. The production of the dragon fruit wine involves peeling the dragon fruit using the peeling machine 1, pulping the fruit pulp using the pulping machine 2, and then combining the pulp with the juice extracted by the branch and peel juicer 6 in the fermentation tank 8. Yeast is added for fermentation, and the mixture is then filtered through a filter 9 to remove the fruit wine residue. The fruit wine is then aged in the aging barrel 10 for a period of time, sterilized by a sterilizer 15, and finally bottled by a packaging machine 15 to obtain the dragon fruit wine. The fermentation tank is made of ceramic.
[0020] The dragon fruit branch dethorn removal machine 5 is designed based on the triangular prism shape of dragon fruit branches. It includes a dragon fruit branch support plate 21, a front guide block 22, a blade mounting body 23, a rear guide block 24, a dethorn removal branch outlet guide plate 25, and a burr collection bin 26. The dragon fruit branch support plate 21 is installed in front of the front guide block 22, and the blade mounting body 23 is installed between the front guide block 22 and the rear guide block 24. The outlet of the rear guide block 24 is equipped with a dethorn removal branch outlet guide plate 25 and a burr residue collection box 26. The dragon fruit branch enters the front guide block 22 and the blade mounting body 23 from the dragon fruit branch support plate 21 to remove the burrs on the branch. Then, it is guided by the rear guide block 24 to the dethorn removal branch guide plate 25 and enters the dragon fruit branch and peel press 6 to extract juice. The burr residue falls into the burr collection box 26. The dragon fruit branch inlet tray 21 is equipped with a pushing mechanism or robot arm on both sides to straighten the branch into the front guide block 22 and pass through the triangular through hole 233 in the middle of the blade mounting body 23. The blade removes the burrs on the edge of the branch.
[0021] The aforementioned front guide block 22 and rear guide block 24 can also be designed as an automatic transmission device, so that the removal of burrs on the branches by the blade can be automated.
[0022] The dragon fruit branch thorn removal machine 5 can be installed on the panel 27 of the frame 28. The frame 28 has a caster mounting bracket 29 at the bottom and casters 30 at the bottom, which can be moved easily. It can also be installed directly next to the dragon fruit branch and peel press 6.
[0023] The blade mounting body 23 is mounted on the panel 27 by screws. The blade mounting body 23 is provided with three blades 232 and three blade adjusters 234, corresponding to the triangular prism of the dragon fruit branch. The blade mounting body 23 has a triangular through hole 233 in the middle. When the branch passes through the triangular through hole 233, the burrs on the side of the branch are cut off by the three blades 232. The three blades are provided with springs 231 above them, so that branches of different sizes can cut the burrs of the branch through the extension and retraction of the blades 232 and the springs 231.
[0024] The dragon fruit wine filter 9 can be made using various methods or equipment, such as microporous filtration, gauze filtration, plate and frame filtration, etc., to obtain clear dragon fruit wine after filtration.
[0025] Dragon fruit seeds have a hard surface and contain a protective gelatinous film that cannot be broken down during fermentation, remaining only in the pulp. The inventors ground these seeds in a grinder (12) to create a dragon fruit health beverage. Our analysis shows that this dragon fruit health beverage is similar to dragon fruit wine because the dragon fruit pulp, pressed dragon fruit branches, and dragon fruit peel juice are rich in vitamins, trace elements, and polyphenols. Furthermore, the ground dragon fruit seeds are rich in dietary fiber, fat, and high-quality protein, all of which are extremely beneficial to the human body.
[0026] The following are the results of testing conducted on February 5, 2026, at the Institute of Agricultural Product Processing and Food Nutrition, Beijing Academy of Agricultural and Forestry Sciences, on the fruit wine of Example 1 of this invention:
[0027] It is evident that the dragon fruit wine produced by this invention contains 615 mg / L of potassium and 79.8 mg / L of magnesium, offering numerous health benefits, specifically: Lowering blood pressure: Potassium works by influencing the body's sodium balance, while magnesium improves blood circulation by relaxing blood vessel walls. The synergistic effect of these two minerals effectively lowers blood pressure and reduces the risk of cardiovascular disease. Maintaining myocardial function: Potassium is an important cation within myocardial cells, maintaining normal myocardial function, including excitability, conductivity, and contractility. Sufficient potassium intake also promotes sodium excretion, thereby lowering blood pressure. Preventing stroke: Potassium protects vascular endothelial cells, reduces vascular damage, and prevents stroke. Improving diabetic complications: Potassium improves insulin sensitivity, helps control blood sugar levels, and prevents diabetic complications. Promoting protein metabolism: Potassium promotes protein synthesis, aiding in body growth and repair.
[0028] In summary, the inventors believe that because the fruit wine produced using the equipment and process of this invention, the resulting dragon fruit wine and beverage have a mellow taste and are rich in vitamin C, vitamin B, carotene, and various minerals such as potassium, magnesium, calcium, phosphorus, and iron. They also contain polysaccharides, flavonoids, phenols, and other chemical components that are easily absorbed. The alkaloids are its main pharmacologically active components, possessing pharmacological effects such as lowering blood pressure, improving memory, anti-aging, lowering blood pressure, blood sugar, and cholesterol, protecting nerves, and anti-tumor activity. It is an excellent product for regulating blood pressure and for daily health maintenance. This is why the dragon fruit wine and beverages of this invention are generally suitable for men, women, and the elderly with weak constitutions. Dietary fiber can promote gastrointestinal motility, improve constipation, and benefit the stomach, intestines, liver, and kidneys; moreover, it can retain its activity in the bloodstream for 75 hours, helping to prevent cardiovascular diseases and other illnesses. This has a theoretical basis in the traditional Chinese medicine theory we advocate today.
