Description

Technical Field

[0001] The utility model relates to the field of deep processing of crops, in particular to a preheating and degassing device for black wolfberry concentrated juice. Background Art

[0002] Black wolfberry, also known as black wolfberry, contains a variety of nutrients such as protein, vitamins and minerals, and its nutritional value is higher than that of ordinary wolfberry. In order to extend the shelf life of black wolfberry, it can be processed into black wolfberry concentrated juice. Before preparing concentrated juice, black wolfberry needs to go through the processes of cleaning, crushing, beating and seed removal, and fine grinding to obtain black wolfberry pulp. During the processing, a large amount of air will be incorporated into the black wolfberry pulp, which requires preheating and degassing of the pulp to remove the non-condensable gas contained in the pulp, inhibit the oxidation of substances in the pulp, and avoid the gas affecting the product quality.

[0003] At present, black wolfberry puree is generally preheated and degassed by a vacuum degasser. The existing vacuum degasser injects the slurry directly into the degassing tank and uses a vacuum pump to evacuate the tank. On the one hand, the black wolfberry puree in the tank is in a static state, and the air in the deep layer is not easy to be discharged, affecting the degassing effect; on the other hand, after the black wolfberry puree is degassed, the top cover needs to be opened for cleaning, which is not very convenient to operate.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to provide a black wolfberry concentrated juice preheating and degassing device with scientific design, good degassing effect, convenient cleaning and strong practicality in view of the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a black wolfberry concentrated juice preheating and degassing device, including a degassing tank, a discharge pump, a vacuum pump, a feed pipe and a circulating pump, the top of the degassing tank is connected to the exhaust port of the vacuum pump through an exhaust pipe, the bottom end of the degassing tank is connected to the feed port of the discharge pump through a discharge pipe, the feed pipe is penetrated through the top of the degassing tank, the discharge pipe is connected to the liquid inlet of the circulation pump through a circulation pipeline, the liquid outlet of the circulation pump is connected to the feed pipe through a branch pipe, and valves are provided on the circulation pipeline and the feed pipe.

[0007] Based on the above, the liquid outlet of the feed pipe extends to the center of the degassing tank, and an umbrella-shaped water distribution plate is also provided in the degassing tank, and the umbrella-shaped water distribution plate is located directly below the liquid outlet of the feed pipe.

[0008] Based on the above, the circulation pipeline is also connected to a water inlet branch pipe, and a valve is also provided on the water inlet branch pipe.

[0009] Based on the above, a horizontal skirt is provided at the bottom end of the umbrella-shaped water distribution plate.

[0010] Based on the above, a connecting rod is connected to the top of the umbrella-shaped water distribution plate, and the top of the connecting rod extends into the liquid outlet of the feed pipe and is connected to the inner wall of the feed pipe.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) By providing the circulation pump, the bottom layer of the puree can be continuously circulated to the upper layer, thereby accelerating the discharge of air from the deep part of the puree; by providing the umbrella-shaped water distribution plate, the black wolfberry puree entering from the feed pipe will be spread into a thin film on the surface of the umbrella-shaped water distribution plate, making it easier to extract the air, thereby improving the degassing effect.

[0013] (2) When cleaning is required, the water inlet branch pipe is connected separately, and the water inlet branch pipe provides water to the circulation pump, and the water also flows through the surface of the umbrella-shaped water distribution plate and the inner wall of the degassing tank to achieve cleaning; by setting the horizontal skirt, the fluid can be guided to turn at the bottom end of the umbrella-shaped water distribution plate. With this design, a small flow rate can be used when circulating the slurry, and a large flow rate can be used when cleaning. In this way, the cleaning trajectory of the water will cover the flow trajectory of the slurry, so that the cleaning effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0018] like Figure 1 and Figure 2As shown, a black wolfberry concentrated juice preheating and degassing device comprises a degassing tank 1, a discharge pump 2, a vacuum pump 3, a feed pipe 4 and a circulation pump 5. The top of the degassing tank 1 is connected to the suction port of the vacuum pump 3 through a suction pipe 6 to provide a negative pressure environment in the tank. The bottom end of the degassing tank 1 is connected to the feed port of the discharge pump 2 through a discharge pipe 7. The feed pipe 4 is penetrated through the top of the degassing tank 1. The discharge pipe 4 is connected to the liquid inlet of the circulation pump 5 through a circulation pipeline 8. The liquid outlet of the circulation pump 5 is connected to the feed pipe 4 through a branch pipe. The liquid outlet of the feed pipe 4 The outlet extends to the center of the degassing tank 1. An umbrella-shaped water distribution plate 9 is also provided in the degassing tank 1. The umbrella-shaped water distribution plate 9 is located just below the liquid outlet of the feed pipe 4. A connecting rod 13 is connected to the top of the umbrella-shaped water distribution plate 9. The top of the connecting rod 13 extends into the liquid outlet of the feed pipe 4 and is connected to the inner wall of the feed pipe 4. After the circulating pump 5 is started, the bottom layer of raw pulp is continuously circulated to the upper layer. The black wolfberry raw pulp entering from the liquid outlet of the feed pipe 4 will expand into a thin film on the surface of the umbrella-shaped water distribution plate 9, making it easier to extract the air, thereby improving the degassing effect.

[0019] In order to facilitate cleaning, the circulation pipeline 8 is also connected to a water inlet branch pipe 10, and valves 11 are provided on the circulation pipeline 8, the feed pipe 4 and the water inlet branch pipe 10; by switching the three valves 11, the raw slurry feeding, slurry circulation and water inlet cleaning functions can be realized.

[0020] In order to improve the cleaning effect, a horizontal skirt 12 is provided at the bottom end of the umbrella-shaped water distribution plate 9. The horizontal skirt 12 forms a turning point at the bottom end of the umbrella-shaped water distribution plate 9. When the fluid flow rate in the feed pipe 4 is greater, the fluid diffuses to the surrounding area when passing through the turning point. By utilizing this characteristic, a low flow rate can be used during slurry circulation, and a high flow rate can be used during cleaning to achieve a good flushing effect.

[0021] Working principle:

[0022] First, close the valve 11 on the circulation pipeline 8 and the water inlet branch pipe 10, open the valve 11 on the feed pipe 4, turn on the vacuum pump 3, and the black wolfberry pulp enters the degassing tank 1. After a certain amount is pumped in, close the valve 11 on the feed pipe 4 and the water inlet branch pipe 10, open the valve 11 on the circulation pipeline 8, and the black wolfberry pulp begins to circulate in the tank. Each time the black wolfberry pulp is discharged from the liquid outlet of the feed pipe 4, it flows through the surface of the umbrella-shaped water distribution plate 9 to form a thin film, making it easier to extract air. After degassing is completed, turn on the discharge pump 2 to discharge the slurry; when cleaning is required, close the valve 11 on the feed pipe 4 and the circulation pipeline 8, open the valve 11 on the water inlet branch pipe 10, and water enters from the liquid outlet of the feed pipe 4, flows through the surface of the umbrella-shaped water distribution plate 9 and the inner wall of the degassing tank 1 to achieve cleaning.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
