Description

Technical Field

[0001] The invention belongs to the technical field of juice extraction equipment, and in particular relates to a mulberry juice processing and preparation device. Background Art

[0002] Mulberries are a nutritious fruit, which are usually squeezed to obtain mulberry juice and prepared into fruit juice drinks or fruit wine drinks. However, the existing mulberry juice squeezing equipment is generally a non-vacuum sealed operating environment, which causes the mulberry fruit to contact with the air during the crushing and juicing process. On the one hand, during the crushing and juicing process of the mulberry fruit, the aroma components carried by the mulberry fruit itself will diffuse into the air environment during the crushing process, causing some of the aroma components to volatilize and dissipate, thereby causing the obtained mulberry juice to lack the original aroma and flavor of the mulberry; on the other hand, after the mulberry fruit tissue is destroyed during the crushing and juicing process, it is very easy to contact with oxygen in the air to cause browning, causing the color of the mulberry juice to deepen. Especially for white mulberries, it is difficult to ensure the original color of the mulberry juice. At the same time, the browning phenomenon causes the loss and loss of nutrients such as amino compounds and ascorbic acid, affecting the nutritional value of the obtained mulberry juice.

[0003] Therefore, it is necessary to design a mulberry juice processing and preparation device that can effectively solve the above problems and defects. Summary of the invention

[0018] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in conjunction with specific implementation methods.

[0019] Example like Figure 1~Figure 5 As shown, the present invention provides a mulberry juice processing and preparation device, including a cleaning cylinder 1, an isolation cylinder 2 and a vacuum juice extraction box 3 which are fixedly connected from top to bottom and connected in sequence, the cleaning cylinder 1 is used for cleaning mulberry fruits, the isolation cylinder 2 is used for temporarily storing the cleaned mulberry fruits and transporting the mulberry fruit raw materials to the vacuum juice extraction box 3 at intervals, and the vacuum juice extraction box 3 is used for crushing and juicing the mulberry fruit raw materials and ensuring that the processing process is in a vacuum environment.

[0020] Combination Figure 2 and Figure 3 As shown, the washing cylinder 1 is provided with a washing cavity for washing mulberries, and a feed port 12 and a water inlet 13 connected to the washing cavity are provided at the top of the washing cylinder 1. The washing cylinder 1 is also provided with a drain port 14 and a drain pan 11 arranged near the bottom thereof, and the drain port 14 is connected to the washing cavity to discharge the water after washing the mulberries, and the drain pan 11 is arranged in the washing cavity and fixedly connected to the inner wall of the washing cylinder 1, and the drain pan 11 is provided with a plurality of drain holes 111 distributed at intervals, and the drain port 14 is located below the drain pan 11. In specific use, the water inlet 13 and the drain port 14 can be connected to an external water pump to pump the washing water into the washing cavity to wash the mulberries.

[0021] Furthermore, the cleaning cylinder 1 is also provided with a stirring assembly 7, see Figure 2As shown, the stirring assembly 7 includes a stirring motor 71 fixedly arranged on the top of the cleaning cylinder 1 and a stirring blade 72 rotatably arranged in the cleaning chamber, the stirring blade 72 is connected to the output shaft of the stirring motor 71, and the drain tray 11 is located below the stirring blade 72, so that the cleaning liquid passes through the drain hole 111 of the drain tray 11 and is finally discharged through the drain port 14.

[0022] The isolation cylinder 2 is fixedly arranged below the cleaning cylinder 1, and is provided with a vacuum isolation chamber for temporarily storing mulberry fruit raw materials. Figure 2 and Figure 3 As shown, the vacuum isolation chamber is connected with the cleaning chamber through a feeding pipe 5. The feeding pipe 5 passes through the bottom of the cleaning cylinder 1 and partially extends into the cleaning chamber, and its end is fixedly connected to a drain pan 11. The drain pan 11 is provided with a feed hole 112 adapted to the feeding pipe 5. Mulberry fruits flow into the feeding pipe 5 through the feed hole 112.

[0023] like Figure 1 , Figure 2 As shown, the feeding pipeline 5 is provided with a first vacuum valve 51 fixedly connected thereto, and the mulberry fruit raw material flows into the vacuum isolation chamber through the opening and closing control of the first vacuum valve 51, and the isolation cylinder 2 is provided with a first vacuum pump 21 connected to its vacuum isolation chamber to evacuate the vacuum isolation chamber. Specifically, the first vacuum valve 51 is sealed and connected to the feeding pipeline 5, and it can be a large-caliber vacuum butterfly valve or vacuum gate valve to ensure that the mulberry fruit can flow into the vacuum isolation chamber through the first vacuum valve 51 and the feeding pipeline 5, such as a VAT64.2 series high vacuum gate valve, or a VAT61.3 series high vacuum butterfly valve, the size of which can be DN100-400mm. It should be noted that the specific specifications and dimensions of the first vacuum valve 51 can be adjusted and set according to the actual processing and production requirements, and here only the basic condition that the mulberry fruit raw material can flow through the pipeline is limited.

[0024] Optionally, in some embodiments, the isolation cylinder 2 is a conical sealing cylinder that is narrow at the top and wide at the bottom, so as to ensure that the mulberry fruit raw materials can automatically accumulate and flow downward under the action of their own gravity. Furthermore, the volume of the isolation cylinder 2 is smaller than the volume of the vacuum juice box 3. Specifically, the volume of the isolation cylinder 2 is 1 / 3 to 1 / 5 of the volume of the vacuum juice box 3, so that it is convenient to repeatedly vacuumize the isolation cylinder 2. Compared with repeatedly vacuumizing the vacuum juice box 3 with a larger volume, it can reduce the processing cost and improve the processing efficiency of mulberry juice to achieve continuous processing of mulberry fruits.

[0025] The vacuum juice extraction box 3 is arranged below the isolation cylinder 2, and is provided with a vacuum juice extraction chamber for crushing and juicing the mulberry fruit raw materials. Figure 2 and Figure 4As shown, the vacuum juicing chamber is connected to the vacuum isolation chamber through the discharge pipe 6, that is, the two ends of the discharge pipe 6 are respectively fixedly connected and connected to the bottom of the isolation cylinder 2 and the top of the vacuum juicing box 3, and the discharge pipe 6 is provided with a second vacuum valve 61 fixedly connected thereto, and the mulberry fruit raw material flows from the vacuum isolation chamber to the vacuum juicing chamber through the opening and closing control of the second vacuum valve 61. The models and specifications of the second vacuum valve 61 and the first vacuum valve 51 can refer to the above description of the first vacuum valve 51, which will not be repeated here. It should be noted that during use, at least one of the first vacuum valve 51 and the second vacuum valve 61 is ensured to be in a closed state, so that the isolation cylinder 2 plays the role of isolating the normal pressure cleaning cylinder 1 and the vacuum juicing box 3.

[0026] The vacuum juice extraction box 3 is provided with a second vacuum pump 34 which is connected with its vacuum juice extraction chamber to evacuate the vacuum juice extraction chamber into a vacuum state, thereby ensuring that the mulberry fruit raw materials are in a vacuum environment during the crushing and juicing process, thereby avoiding the volatilization and escape of aroma components during the crushing and juicing process, and avoiding browning due to contact with oxygen, thereby ensuring the purity of the color of the mulberry juice and avoiding the loss of nutrients.

[0027] The vacuum juice extraction box 3 is provided with a pressing assembly 4 located in the vacuum juice extraction chamber. Figure 2 , Figure 4 and Figure 5 As shown, the pressing assembly 4 includes at least four tensioning rollers 41 arranged in parallel in the vacuum juice extraction chamber, a closed-loop filter belt 42 rotatably wound around the outer edge of the four tensioning rollers 41, a main pressing roller 43 arranged on the outside of the closed-loop filter belt 42 and abutting against it, and a juice collecting plate 44 arranged on the inside of the closed-loop filter belt 42.

[0028] Specifically, in this embodiment, four tensioning rollers 41 are provided as an example for description.

[0029] refer to Figure 5As shown, four tension rollers 41 support the closed-loop filter belt 42 and tension the closed-loop filter belt 42. The two ends of the tension rollers 41 are rotatably fixed on the side walls of the vacuum juice box 3, and the two tension rollers 41 at the top are arranged on both sides of the discharge pipe 6, so that the mulberry fruit raw materials flowing into the vacuum juice chamber through the discharge pipe 6 will fall on the closed-loop filter belt 42. The main rolling roller 43 is arranged in parallel with the tension rollers 41 and is arranged between the two tension rollers 41 at the top. The two ends of the main rolling roller 43 are rotatably fixed on the side walls of the vacuum juice box 3, and the main rolling roller 43 is provided with a main driving motor 431 connected thereto to drive the main rolling roller 43 to rotate and squeeze the mulberry fruit raw materials rolled between the main rolling roller 43 and the closed-loop filter belt 42, and the mulberry juice flows through the closed-loop filter belt 42 into the juice collection tray 44 below for collection. The main driving motor 431 is fixedly arranged on the side wall of the vacuum juice extraction box 3. Specifically, the main crushing roller 43 and one of the two tensioning rollers 41 on the top are arranged on both sides of the port of the discharge pipe 6, so that the mulberry fruit raw materials fall onto the closed-loop filter belt 42 and are crushed and juiced by the main crushing roller 43. The juice collecting tray 44 is located directly below the main crushing roller 43.

[0030] Optionally, in some embodiments, the pressing assembly 4 also includes at least one auxiliary rolling roller 45 arranged on the outside of the closed-loop filter belt 42 and abutting against it. The auxiliary rolling roller 45 is arranged parallel to the main rolling roller 43 and is located between the two top tensioning rollers 41. The two ends of the auxiliary rolling roller 45 are rotatably fixed on the side walls of the vacuum juice box 3. The auxiliary rolling roller 45 is provided with an auxiliary drive motor 451 connected to it to drive the auxiliary rolling roller 45 to crush and juice the mulberry fruit residue again. The juice collection tray 44 is located directly below the main rolling roller 43 and the auxiliary rolling roller 45.

[0031] Combination Figure 1 and Figure 5 As shown, the vacuum juice extraction box 3 is also provided with a residue collection box 35 located outside the closed-loop filter belt 42 and close to the bottom. The residue collection box 35 is located in the vacuum juice extraction chamber and directly below the closed-loop filter belt 42 to collect mulberry residue after the crushing and juicing process. The residue collection box 35 is sealed and connected to the vacuum juice extraction box 3.

[0032] Further, such as Figure 1 and Figure 5 As shown, the vacuum juice extraction box 3 is also provided with a liquid collecting box 31 connected with the juice collecting tray 44 through a liquid collecting pipe 32, and the liquid collecting pipe 32 is provided with a third vacuum valve 33 fixedly connected thereto. The liquid collecting pipe 32 runs through the side wall of the vacuum juice extraction box 3, one end of which extends into the vacuum juice extraction chamber and is connected to the juice collecting tray 44, and the other end is connected to the liquid collecting box 31 located outside the vacuum juice extraction box 3.

[0033] The liquid collecting box 31 is provided with a liquid taking port connected to the interior thereof, and mulberry juice can be collected through the liquid taking port. It should be noted that an ordinary valve can be provided at the liquid taking port, and a vacuum valve similar to the third vacuum valve 33 can also be provided. The setting can be specifically adjusted according to needs, and the third vacuum valve 33 can select a vacuum valve commonly used in the art, which is not specifically limited or elaborated here.

[0034] Optionally, in some embodiments, the juice collection tray 44 is in an inverted pyramid shape, so that the mulberry juice squeezed through the closed-loop filter belt 42 can be gathered and collected and flowed into the liquid collection box 31 through the liquid collection pipe 32 .

[0035] like Figure 1 and Figure 2 As shown, the mulberry juice processing and preparation device provided in this embodiment also includes a fixed bracket 8 arranged between the cleaning cylinder 1 and the vacuum juice extraction box 3, the top of the fixed bracket 8 is fixedly connected to the bottom of the cleaning cylinder 1, and the bottom is fixedly connected to the top of the vacuum juice extraction box 3, so as to improve the stability and reliability of the fixing of the cleaning cylinder 1 and the isolation cylinder 2. Furthermore, the fixed bracket 8 is provided with a support frame fixedly connected thereto, and the first vacuum pump 21 is fixedly arranged above the support frame.

[0036] During specific use, first close the first vacuum valve 51, the second vacuum valve 61 and the third vacuum valve 33, so that the cleaning chamber of the cleaning cylinder 1, the vacuum isolation chamber of the isolation cylinder 2 and the vacuum isolation chamber of the vacuum juice box 3 are in a completely independent and isolated state; operate the second vacuum pump 34 to evacuate the vacuum juice box 3 into a vacuum environment state, and put the mulberry fruit raw material into the cleaning chamber through the feed port 12 of the cleaning cylinder 1 for cleaning; open the first vacuum valve 51 to connect the cleaning cylinder 1 with the isolation cylinder 2, and feed the cleaned mulberry fruit raw material through the feeding pipe The mulberry fruit raw materials in the isolation cylinder 2 are transported to the isolation cylinder 2 through the discharge pipe 5; then the first vacuum valve 51 is closed, and the first vacuum pump 21 is operated to evacuate the isolation cylinder 2 into a vacuum environment state (the same as the vacuum degree of the vacuum juice box 3); then the second vacuum valve 61 is opened, the isolation cylinder 2 is connected with the vacuum juice box 3, and the mulberry fruit raw materials in the isolation cylinder 2 fall into the vacuum juice box 3 through the discharge pipe 6 for juicing; after all the mulberry fruit raw materials in the isolation cylinder 2 have completed the juicing process, the second vacuum valve 61 is closed; the above operations are repeated to complete the continuous cleaning and juicing process of the mulberry fruit.

[0037] It should be noted that, in the above-mentioned juicing process of mulberry fruits, the third vacuum valve 33 is in an open state, and the liquid collecting box 31 is in a sealed closed state, so that the mulberry juice collected by the juice collecting plate 44 flows into the liquid collecting box 31 through the liquid collecting pipe 32. When it is necessary to take or transfer the mulberry juice in the liquid collecting box 31, the third vacuum valve 33 needs to be closed, so that the internal cavity of the liquid collecting box 31 is isolated from the vacuum juicing cavity of the vacuum juicing box 3, so as to avoid affecting the vacuum environment of the vacuum juicing box 3.

[0038] In summary, the mulberry juice processing and preparation device provided by the present invention can be used for juicing mulberry fruits, while ensuring that the crushing and juicing process is in a vacuum operating environment, effectively reducing the volatilization of aroma components during the crushing and juicing process, as well as the color changes and loss of nutrients caused by browning, thereby retaining the original flavor and nutritional value of mulberries.

[0039] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
