Description

Technical Field

[0001] The utility model relates to a juicer, in particular to a juice extraction device and a fruit and vegetable puncturing, blanching and juicing machine with the same. Background Art

[0002] When making Qinzhou cucumber peel, it is necessary to first puncture the cucumbers, then squeeze out some of the cucumber juice, and take them out after soaking in brine for a set time. However, since cucumbers are characteristic agricultural products in Lingnan, and the cucumber peel industry is a traditional characteristic industry in Lingnan with certain regionality. So far, most cucumber peel processing enterprises are small workshops, mainly using manual puncturing and juicing. There are also research institutions and manufacturers in China that have developed some juice extractors and put them on the market, such as belt-type juice extractors and LGLY vertical continuous juice pressing and filtering machines. However, they are mainly for extracting fruit juice, completely destroying the appearance of fruits and vegetables, and not considering the integrity of the appearance of cucumber peels. However, according to the production process of cucumber peel, it is required that after the cucumbers are punctured, some of the cucumber juice is slightly squeezed out for pickling, but during the squeezing process, the perfect appearance of the cucumbers should be ensured, resulting in a relatively complex structure of the puncturing and squeezing machine.

[0003] Chinese Patent Application CN105077093A discloses a cucumber pressing device, which presses the blanched cucumbers through a pressing roller and a bearing roller to meet the technical requirements of being able to press juice without crushing the cucumbers. However, in this cucumber pressing device, the arrangement direction of the pressing rollers and the arrangement direction of the bearing rollers are substantially parallel. When the cucumbers are conveyed from the feeding end to the discharging end, they will be gradually thinned by the pressing rollers and the bearing rollers. If the arrangement direction of the pressing rollers and the arrangement direction of the bearing rollers are parallel, when the thinned cucumbers move near the discharging end, the pressing effect of the pressing rollers and the bearing rollers on them will be weakened, and it is difficult to achieve the required pressing effect. Summary of the Invention

[0004] The utility model aims to solve the above-mentioned technical problems and provides a juice extraction device that can avoid the weakening of the pressing effect during the pressing process.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

During use, the fruits and vegetables enter from the end with a larger height of the pressing space, and the end with the smallest height of the pressing space is the discharging end. During the conveying process, the fruits and vegetables are gradually pressed thinner under the cooperation of the pressing rollers and the pressure-bearing components until the slag is discharged at the discharging end with the smallest height of the pressing space. In view of the phenomenon that the fruits and vegetables will be pressed thinner after juicing, the height of the pressing space of the above juice extraction device gradually decreases along the conveying direction of the conveyor belt, so that the pressing effect on the fruits and vegetables can be avoided from weakening during the pressing process.

[0021] In the above fruit and vegetable punching, blanching and juicing machine, the punching device and the juice extraction device are integrated to obtain an automatic punching and juicing all-in-one machine suitable for deep processing of fruits and vegetables, especially suitable for deep processing of cucumbers.

The plurality of pressing rollers 537 and the conveying portion 534 enclose a pressing space 538 for fruits and vegetables to enter. The height of the pressing space 538 gradually decreases along the conveying direction of the conveyor belt 533. The highest point of the height of the pressing space 538 is the feeding end for fruits and vegetables to enter the pressing space 538, and the lowest point of the height of the pressing space 538 is the discharging end. During the conveying process, the fruits and vegetables are gradually pressed thin under the cooperation of the pressing rollers 537 and the pressure-bearing assembly 531 until they are discharged from the discharging end at the lowest point of the height of the pressing space 538 for residue removal.

[0047] In this embodiment, the conveying portion 534 is horizontally arranged. The plurality of pressing rollers 537 are arranged closely in sequence, and the arrangement direction of the plurality of pressing rollers 537 is inclined relative to the horizontal plane to enclose the pressing space 538 with the plurality of pressing rollers 537. A plurality of mesh holes are also arranged at intervals on the conveyor belt 533, and a juice collection tank 54 is provided at the bottom of the conveyor belt 533 and located below the mesh holes.

[0048] The juice extraction device 50 further includes a lifting mechanism 56.

[0049] It can be understood that the juice extraction device 50 may further include a driving mechanism for driving the driving transmission wheel 532 and several pressing rollers 537 to rotate, etc. This part belongs to the prior art. For example, reference can be made to a cucumber pressing device disclosed in Chinese Patent Application CN105077093A. To save space, it will not be elaborated here.

[0050] Please refer to again Figure 1 , the fruit and vegetable puncturing, blanching and juicing machine 100 further includes a scraper conveyor 60. The scraper conveyor 60 is arranged between the blanching device 30 and the juice extraction device 50. The input end of the scraper conveyor 60 is docked with the discharge end of the second conveying mechanism 34, and the output end of the scraper conveyor 60 is docked with the feeding end of the juice extraction device 50.

[0051] When the fruit and vegetable puncturing, blanching and juicing machine 100 is in use, fruits and vegetables, such as cucumbers, are placed in the feeding hopper 17. The cucumbers fall from the feeding hopper 17 to the feeding end of the first conveying mechanism 12, and then are conveyed by the first conveying mechanism 12 to the cucumber supporting mechanism 16. A plurality of cucumber pushing blades 163 on the cucumber pushing roller 161 are used to make the cucumbers arranged flat on the first conveying mechanism 12. The flat cucumbers enter the puncturing mechanism 14. The rotation of the rotating arm 143 drives the needle disc 145 to move up and down, so as to puncture the cucumbers on the first conveying mechanism 12. Specifically: under the action of the differential 125, the first conveying mechanism 12 makes an intermittent movement of stop → move → stop. When the cucumbers are being punctured, the differential 125 makes the roller 121 stop rotating. At this time, the cucumbers stay on the first conveying mechanism 12, and the needle disc 145 drives the puncturing needles 146 to move downward to puncture the cucumbers. After the puncturing is completed, the differential 125 makes the roller 121 continue to rotate, and the needle disc 145 drives the puncturing needles 146 and the cucumbers on the puncturing needles 146 to move upward together. When the cucumbers abut against the cucumber discharging plate 147, the cucumbers are separated from the puncturing needles 146 and fall onto the first conveyor belt 123 of the first conveying mechanism 12 for conveying. The setting of the differential 125 can prevent the puncturing needles 146 from being bent and ensure the smooth progress of puncturing and conveying.

[0052] The punctured cucumbers fall onto the second conveying mechanism 34 and are conveyed by the second conveying mechanism 34 into the constant temperature water tank 32 for blanching. The blanched cucumbers are conveyed to the juice extraction device 50 by the scraper conveyor 60 for pressing. During pressing, the fruits and vegetables enter between the pressing rollers 537 and the pressure bearing assembly 531 from the highest point of the pressing space 538. The fruits and vegetables are gradually pressed thin under the cooperation of the pressing rollers 537 and the pressure bearing assembly 531 until they are conveyed to the discharge end at the lowest height of the pressing space 538 to discharge residue. The squeezed cucumber juice falls into the juice collection tank 54 through the mesh holes for collection, and subsequent products such as cucumber juice can be made. The cucumbers falling from the discharge end of the pressing space 538 can be pickled later to obtain cucumber peel products. Squeezing the cucumbers slightly after puncturing to discharge some cucumber juice and then pickling can reduce the consumption of salt and save the pickling time.

[0053] In the above-mentioned juice extractor 50, the height of the pressing space 538 formed by enclosing a number of pressing rollers 537 and the conveying part 534 gradually decreases along the conveying direction of the conveyor belt 533. During use, fruits and vegetables enter from the end with a larger height of the pressing space 538, and the end with the smallest height of the pressing space 538 is the discharge end. During the conveying process, the fruits and vegetables are gradually pressed thinner under the cooperation of the pressing rollers 537 and the pressure-bearing assembly 531 until the residue is discharged at the discharge end with the smallest height of the pressing space 538. In view of the phenomenon that the fruits and vegetables will be pressed thinner after juicing, the height of the pressing space 538 of the above-mentioned juice extractor 50 gradually decreases along the conveying direction of the conveyor belt 533, so that the weakening of the pressing effect on the fruits and vegetables can be avoided during the pressing process.

[0054] The above-mentioned fruit and vegetable puncturing, blanching and juicing machine 100 integrates the puncturing device 10 and the juice extractor 50 to obtain an automatic puncturing and juicing all-in-one machine suitable for deep processing of fruits and vegetables, especially suitable for deep processing of cucumbers. It can process fresh cucumbers into cucumber peel products and cucumber juice beverages at the same time, improve the automation level of fresh cucumber processing equipment, and is of great significance for improving the comprehensive value of fresh cucumbers, improving production efficiency and reducing the production cost of cucumber peels. At the same time, the above-mentioned fruit and vegetable puncturing, blanching and juicing machine 100 is also provided with a blanching device 30 in front of the juice extractor 50. During use, after the cucumbers are punctured, they are blanched first to make the cucumbers slightly softer before pressing, which can ensure that the cucumbers can be juiced without being crushed.
