Description

Technical Field

[0001] The present invention belongs to the technical field of preserved fruit pickling and processing, and particularly relates to a vacuum tumbler without wall sticking and a using method thereof. Background Art

[0002] Cranberries are a kind of berries rich in nutrients. The pulp contains abundant substances such as proanthocyanidins, ellagic acid, phenolic acids, resveratrol, etc., and has antibacterial effects; many studies have shown that cranberries can inhibit the infection of Helicobacter pylori and have good effects on preventing gastric ulcers, gastric cancer, and duodenal ulcers. In addition, the flavonoid compounds in cranberries have antioxidant functions in both in vivo and in vitro experiments. Especially, flavonols and proanthocyanidins have a preventive effect on atherosclerosis. Cranberries also have functions such as lowering blood pressure, preventing urinary tract infections, and preventing cardiovascular diseases, and have various health care functions such as laxative, cholesterol reduction, and antiviral, so they are loved by more and more consumers. However, due to the production area limitation of cranberries, as well as their short shelf life and high freshness preservation difficulty, more of them enter the consumers' field of vision as dried cranberries and cranberry juice.

[0003] During the production process of cranberry preserved fruits, sugar pickling is required to increase the sweetness of the finished product and maintain the texture and color of the fruits. In industrial production of cranberry preserved fruits, sugar pickling is generally completed in a tumbler. However, the existing tumblers are all designed for meat product pickling. For example, Chinese Patent CN116569945A discloses a vacuum tumbler, including a support table, a bumping frame, a mounting frame, a drum, and a bumping device. The bumping frame is used for turning the materials, and the bumping device can swing left and right while the drum is rotating, improving the material mixing efficiency and tumbling effect.

[0004] Chinese Patent CN116649393A discloses a vacuum tumbler. When the tumbling cylinder rotates for tumbling, the tumbling shaft rotates relative to the tumbling cylinder, thereby driving the connecting arm and the tumbling plate to revolve around the axis of the tumbling shaft, so that the tumbling plate rotates circumferentially in the tumbling cylinder to beat and impact the ingredients in the tumbling cylinder. At the same time, the connecting arm is driven to rotate around its own axis by a self-rotation driving device, thereby realizing the self-rotation of the tumbling plate to perform a beating operation on different angles of the ingredients, so as to perform comprehensive cutting and tumbling on the ingredients and improve the tumbling efficiency of the ingredients.

[0005] Chinese Patent CN103027098B discloses a vacuum refrigeration tumbler. An intermediate refrigeration chamber is added along the axis inside the tumbling barrel. The intermediate refrigeration chamber and the refrigeration layer form a series-connected cold water circulation system. Blades communicating with the refrigeration layer are arranged on the inner wall of the tumbling barrel. By using the constant temperature principle, the meat products in the tumbling barrel can maintain the same temperature as the cold water at all times. Under the combined action of the refrigeration layer, the intermediate refrigeration chamber and the blades, the temperature of the meat products in the tumbling barrel drops evenly, greatly reducing the local temperature difference. Moreover, the refrigeration speed is fast and the effect is good. Compared with the original vacuum refrigeration tumbler, the refrigeration time can be shortened by one-third, better ensuring the quality of the meat products and keeping the meat products in a fresh state at all times.

[0006] The tumbler for meat products has a greater force in tumbling and beating, which is likely to cause damage to the fruits during the pickling of preserved fruits, affecting the appearance and quality of the products. In addition, a large amount of sugar solution and granular sugar are required during the pickling process of preserved fruits, which are prone to agglomeration or adhesion to the inner wall of the barrel, resulting in uneven mixing of the sugar material and the dried fruits and affecting the product quality. At the same time, a large amount of dried fruits and sugar solution adhering to the barrel wall will affect the capacity of the vacuum tumbler and increase the cleaning difficulty.

The drive motor assembly 6 drives the stirring assembly 17 to rotate forward and backward, thereby realizing the stirring and tumbling pickling of the materials contained in the cylinder body 1 of the vacuum tumbling mixer. At the same time, the stirring assembly 17 rotating forward and backward can prevent the materials from agglomerating due to inertia, further disperse the materials, and improve the pickling uniformity.

[0033] The stirring assembly 17 includes a stirring shaft 171, which is fixedly connected to a plurality of spiral ribbon stirring shafts 174. The spiral ribbon stirring shafts 174 are provided with spiral ribbon stirring long plates 175 and spiral ribbon stirring short plates 176, which stir, mix, and disperse the materials at the middle position inside the cylinder body 1 of the vacuum tumbling mixer.

Each CIP hole ring 71 is provided with a telescopic spray cleaning device 73, and each telescopic spray cleaning device 73 is provided with a cylinder 74. When it is necessary to clean the inner wall of the cylinder body 1 of the vacuum tumbling mixer, the cylinder 74 drives the telescopic spray cleaning device 73 to extend into the cylinder body 1 of the vacuum tumbling mixer, and sprays the CIP water in the CIP water pipe 72 into the cylinder body 1 by using pressure to achieve automatic spray cleaning.

[0037] Further preferably, there are 5 CIP hole rings 71. Two of the CIP hole rings 71 are located at the upper positions near both sides of the cylinder body 1 of the vacuum tumbling mixer to spray and clean both ends of the cylinder body 1 of the vacuum tumbling mixer, and the remaining 3 CIP hole rings 71 are evenly distributed on the top of the cylinder body 1 of the vacuum tumbling mixer to spray and clean the middle position thereof, improving the cleaning efficiency and cleaning effect.

[0038] Further preferably, the telescopic spray cleaning device 73 is provided with evenly distributed spray nozzles to facilitate the spraying of CIP water.

[0039] Preferably, the drive motor assembly 6 includes a motor housing 61. Inside the motor housing 61, there is a motor 62 to protect the motor 62 and prevent external dust and other particulate matters from entering the motor 62, which may affect the motor's lifespan. The bottom of the motor 62 is bolted to the motor mounting plate 64 to fix the motor 62 on the motor mounting plate 64.

[0040] The motor mounting plate 64 is bolted to the bracket 5, and the bracket 5 is fixedly connected to the cylinder base assembly 2, which plays a role in fixing and supporting the motor 62 and the motor housing 61, so that the motor 62 is kept horizontal with the stirring assembly 17.

[0041] The cylinder base assembly 2 is connected to the cylinder jacket leg assembly 3 via a backing plate 4, and the cylinder jacket leg assembly 3 is fixedly connected to the bottom of the vacuum tumbling machine cylinder 1, which plays a role in supporting and fixing the vacuum tumbling machine cylinder 1. There are various heights for the backing plate 4. At the end close to the drive motor assembly 6, the backing plate 4 is thicker, and at the end far from the drive motor assembly 6, the backing plate 4 is thinner, so that the vacuum tumbling machine cylinder maintains a certain inclination angle, generally 1°.

[0042] A motor temperature sensor 63 is provided on the motor housing 61 to detect the operating temperature of the motor 62 in real time and avoid potential safety hazards caused by overheating. The motor housing 61 is provided with heat dissipation holes and a handle, and the handle facilitates the opening and closing of the motor housing 61.

[0043] Preferably, the top of the vacuum tumbling machine cylinder 1 is provided with a first pressure manhole 8, a second pressure manhole 9, a first material port 10, a second material port 11, and a third material port 12. The pressure manhole facilitates maintenance personnel to enter for maintenance. The material ports can directly convey materials such as dried fruits, sugar solutions, and small ingredients into the vacuum tumbling machine cylinder 1 and can be directly connected to the material storage tanks. The top of the vacuum tumbling machine cylinder 1 is also provided with a vacuum port 13 and an evacuation port 14, which are connected to a vacuum device to maintain the vacuum state inside the vacuum tumbling machine cylinder 1. The bottom is provided with a discharge port 20, through which the pickled materials and CIP cleaning water can be discharged.

[0044] Preferably, a heat preservation assembly 16 is provided on the wall of the vacuum tumbling machine cylinder 1 to keep the inside of the vacuum tumbling machine cylinder 1 warm, so that its temperature is maintained at about 40°C, avoiding sugar solidification and accelerating the pickling speed. The heat preservation assembly 16 includes a jacket 161 and a heat preservation layer 162. The jacket 161 is respectively connected to a water inlet 163 and a water outlet 164. The water inlet 163 is located at the bottom of the vacuum tumbling machine cylinder 1, and the water outlet 164 is located on the side wall of the vacuum tumbling machine cylinder 1. Hot water enters the jacket 161 from the water inlet 163, circulates for heat preservation and then is discharged from the water outlet 164. At the same time, the heat preservation layer 162 can reduce heat loss and enhance the heat preservation effect.

[0045] Preferably, a differential pressure detection component 18 and a temperature detection component 19 are provided on the cylinder body 1 of the vacuum tumbler to detect the temperature inside the cylinder and the internal and external differential pressure.

[0046] More preferably, the differential pressure detection component 18 includes a differential pressure orifice ring 181; a static pressure liquid level gasket 182 is provided on the differential pressure orifice ring 181, and a pressure sensor 183 and a static pressure liquid level port 184 are provided on the static pressure liquid level gasket 182, which can detect and display the internal and external differential pressure of the cylinder body 1 of the vacuum tumbler in real time, facilitating the adjustment of the vacuum device to keep the appropriate vacuum degree inside the cylinder; the temperature detection component 19 includes a bracket 191 and a temperature display 192, which can detect and display the temperature inside the cylinder body 1 of the vacuum tumbler in real time, avoiding too high or too low temperature from affecting the tumbling and pickling effect.

[0047] Embodiment 2 A method for using a vacuum tumbler that does not stick to the wall is as follows: (1) Preserving fruits: S1: Turn on the vacuum device connected to the vacuum port 13 and the evacuation port 14 to keep the inside of the cylinder body 1 of the vacuum tumbler in a vacuum state (-40 MPa); S2: Turn on the motor drive component 6 to make the stirring component 17 start to rotate, and at the same time turn on the hot water delivery device to deliver hot water to the jacket 161 to keep the temperature inside the cylinder at 45°C ± 5°C; S3: Then turn on the automatic feeding device to sequentially feed dried fruits, sugar solution, and minor ingredients through the first material port 10, the second material port 11, and the third material port 12 to start the primary pickling of the preserved fruits. After pickling for a period of time, supplement the sugar solution or granulated sugar according to the pickling situation; during the pickling process, the stirring component 7 rotates at a rate of 1 - 3 min / circle, changes the rotation direction every 1 min for positive and negative stirring pickling, and at the same time the side wall scraper 177 and the wing-shaped scraper 178 scrape the materials adhering to the inner wall of the cylinder during the stirring process, and stir under the rotation of the spiral belt stirring long plate 175 and the spiral belt stirring short plate 176; S4: During the pickling process, use the differential pressure detection component 18 to detect the internal and external differential pressure of the cylinder body 1 of the vacuum tumbler in real time to facilitate the adjustment of the vacuum degree; use the temperature detection component 19 to detect the temperature inside the cylinder body 1 of the vacuum tumbler in real time to keep the temperature inside the cylinder moderately at the appropriate pickling temperature, avoiding too high or too low temperature from affecting the pickling effect; S5: After pickling, discharge the materials through the discharge port 20 and enter the next process. After the tumbling and pickling are completed, the damage rate of the cranberry preserved fruits ≤ 1%, and the product quality is relatively high.

[0048] (2) Cleaning: S1: After the pickling of the preserved fruits is completed, empty the materials inside the cylinder body 1 of the vacuum tumbler, and stop the drive motor component 6, so that the stirring component 17 stops rotating; S2: Number the CIP hole rings 71 in the CIP cleaning assembly 7 in order from left to right as the first CIP hole ring, the second CIP hole ring, the third CIP hole ring, the fourth CIP hole ring, and the fifth CIP hole ring. The telescopic spray cleaners 73 and cylinders 74 within each CIP hole ring 71 are also numbered respectively as the first telescopic spray cleaner, the first cylinder, the second telescopic spray cleaner, the second cylinder, the third telescopic spray cleaner, the third cylinder, the fourth telescopic spray cleaner, the fourth cylinder, the fifth telescopic spray cleaner, and the fifth cylinder; S3: Use the first cylinder, the third cylinder, and the fifth cylinder to drive the first telescopic spray cleaner, the third telescopic spray cleaner, and the fifth telescopic spray cleaner to extend into the vacuum tumbling machine cylinder 1 respectively, with the extension length being 30 cm ± 3 cm. Meanwhile, the CIP cleaning water is pressed into the telescopic spray cleaner 73 through the CIP water pipe 72 at a pressure of 5 MPa, and the CIP cleaning water is sprayed out at a certain rate through the spray holes at its end to clean the inner wall of the vacuum tumbling machine cylinder 1; S4: After cleaning for a period of time, use the first cylinder, the third cylinder, and the fifth cylinder to drive the first telescopic spray cleaner, the third telescopic spray cleaner, and the fifth telescopic spray cleaner to move out of the vacuum tumbling machine cylinder 1 respectively. Meanwhile, use the second cylinder and the fourth cylinder to drive the second telescopic spray cleaner and the fourth telescopic spray cleaner to extend into the cylinder respectively, and press the CIP cleaning water in the CIP water pipe 72 into the telescopic spray cleaner at a pressure of 5 MPa, and the CIP cleaning water is sprayed out through the spray holes at its end to clean the inner wall of the corresponding part of the cylinder; The telescopic spray cleaner is of a double-layer structure, with the inner layer being a water spraying assembly containing spray holes and the outer layer being a water conveying assembly containing a sealing sleeve. When the telescopic sprayer extends into the cylinder driven by the cylinder, the water spraying assembly extends out from the water hydrophobic assembly, exposing the spray holes for spraying and cleaning the cylinder; When the telescopic cleaner moves out of the cylinder, the water conveying assembly containing the sealing sleeve outside the water spraying assembly with spray holes wraps it to block the spray holes, thus avoiding the CIP cleaning water from overflowing onto the outer wall of the cylinder and affecting the cleanliness of the workshop. At the same time, the pressure in the CIP water pipe 72 can be concentrated in the telescopic spray cleaners extending into the cylinder, avoiding the sprayed water from being weakened in the cleaning effect on the cylinder due to insufficient pressure.

[0049] S5: After the cleaning is completed, use the second cylinder and the fourth cylinder to drive the second telescopic spray cleaner and the fourth telescopic spray cleaner to move out respectively, close the CIP cleaning assembly 7, and the CIP cleaning water is discharged through the discharge port 20 to end the cleaning.

[0050] Among them, the cylinders use compressed air as the power source. Each cylinder is individually controlled by the master control cabinet, and which cylinder to work is selected from the master control cabinet, so as to select which telescopic washer extends into the cylinder body for cleaning.
