Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, to a low-temperature cold pressing extraction device. Background Technology

[0002] In food production, cold pressing technology has become the mainstream method for lemon juice extraction because it can better preserve the active nutrients and natural flavor of lemons. However, most lemon pressing equipment on the market currently adopts a processing mode that mixes the pulp and peel for extraction, which can only achieve the overall crushing of lemons and extraction of juice, and cannot separate and process the lemon pulp and peel separately.

[0003] During production, the water-soluble vitamin C in lemon pulp is easily encapsulated by the fat-soluble limonene in the peel, leading to reduced nutrient absorption efficiency. Furthermore, the fat-soluble active substances in the peel, such as hesperidin and limonene, are diluted by the large amount of water in the pulp and may react with the fruit acids, resulting in a loss of activity. In addition, limonene from the white pith of the peel can mix into the juice, giving the product a bitter taste.

[0004] Therefore, we made improvements and proposed a low-temperature cold pressing extraction device. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the current whole lemon extraction and processing.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a low-temperature cold pressing extraction device, including a material cylinder. Multiple scrapers are fixedly connected to the inner wall of the material cylinder. A drain opening is provided on the inner side wall of the material cylinder corresponding to each scraper. A shell is fixedly connected to the outer side of the material cylinder, and each drain opening is located inside the shell. A pressing cylinder is provided on one side of the material cylinder, and the top of the pressing cylinder is connected to the bottom of the outer shell via a connecting shell. Extraction components are installed inside both the material cylinder and the pressing cylinder. A forced feeding device is provided on the material cylinder.

[0007] As a preferred technical solution of this application, the extraction component includes a first drive motor, the output end of the first drive motor is fixedly connected to a rotating shaft, and a cutter is fixedly connected to the rotating shaft.

[0008] As a preferred technical solution of this application, the material cylinder is provided with an installation port, and the forced feeding device includes a housing fixedly connected inside the installation port. A conveyor belt is installed inside the housing, and multiple arc-shaped claws are fixedly connected to the outside of the conveyor belt for gripping materials.

[0009] As a preferred technical solution of this application, a second drive motor is fixedly connected to the housing, and the output end of the second drive motor is fixedly connected to the input end of the conveyor belt.

[0010] As a preferred technical solution of this application, both the material cylinder and the pressing cylinder are fixedly connected to a discharge pipe, and each discharge pipe is equipped with a control valve.

[0011] As a preferred technical solution of this application, the top end of the material cylinder is fixedly connected to a feed hopper, and the feed hopper is configured as a cone shape.

[0012] As a preferred technical solution of this application, the bottom of the material cylinder is provided with a base, and the base is provided with an installation groove, and both the material cylinder and the pressing cylinder are installed inside the installation groove.

[0013] As a preferred technical solution of this application, the base has two placement slots, both of which are located below the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. By using a scraper fixed to the inner wall of the cylinder, the peel layer of the lemon can be scraped off during the conveying process to separate the peel from the pulp. Then, by using the combination of the sluice, outer shell, and connecting shell, the peel can be conveyed into the pressing cylinder for subsequent extraction of high-quality material. This effectively avoids the dilution of lemon peel extract by the water and sugar in the pulp when lemon peel is mixed with pulp during extraction, which helps to ensure the activity and flavor of the extract. In addition, the extraction parameters can be adjusted according to the physical characteristics of the lemon peel during extraction. Compared with mixed extraction, the lemon peel can be pressed more fully, effectively improving the extraction rate of target components and reducing raw material waste.

[0017] 2. Through the set forced feeding device, the second drive motor drives the conveyor belt and the arc claw to operate. The arc claw can grab the lemons in the barrel and force them to be conveyed downward, thereby improving production efficiency, ensuring stable lemon feeding, avoiding material jamming, and thus ensuring production efficiency.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The low-temperature cold pressing extraction device includes a material cylinder 1, with a conical feed hopper 10 fixedly connected to the top of the material cylinder 1 to facilitate the feeding of lemon raw materials and prevent material accumulation. Multiple scraper blades 2 are fixedly connected to the inner wall of the material cylinder 1, and each scraper blade 2 has a corresponding opening 3 on its inner side wall. A housing 4 is fixedly connected to the outer side of the material cylinder 1, with each opening 3 located inside the housing 4. A pressing cylinder 5 is located on one side of the material cylinder 1, and the top of the pressing cylinder 5 is connected to the bottom of the housing 4 via a connecting shell 6. Extraction components 7 are installed inside both the material cylinder 1 and the pressing cylinder 5.

[0032] The arrangement of the scraper blades 2 is not limited, but a spiral and uniform distribution is preferred. This ensures that all areas of the lemon's surface are fully scraped as it moves within the cylinder 1, avoiding dead zones and guaranteeing a high scraping rate. The drain 3 allows scraped lemon peel fragments to pass through, ensuring smooth conveying. The outer shell 4 prevents lemon peel fragments from scattering during conveying. The connecting shell 6 is designed as an inclined channel, ensuring that lemon peel fragments smoothly enter the pressing cylinder 5, preparing for subsequent individual pressing.

[0033] Furthermore, such as Figure 5 As shown, the extraction component 7 includes a first drive motor 701, the output end of the first drive motor 701 is fixedly connected to a rotating shaft 702, and a cutter 703 is fixedly connected to the rotating shaft 702.

[0034] It should be noted that there are two pressing components 7, which are installed on the material cylinder 1 and the pressing cylinder 5 respectively, and can respectively process the material inside them. Specifically, the first drive motor 701 can drive the rotating shaft 702 and the cutter 703 to rotate. By controlling their speed, the cold pressing effect can be achieved.

[0035] Example 2

[0036] The low-temperature cold-pressing extraction apparatus provided in Example 1 has been further optimized, specifically, as follows: Figure 4 , Figure 6 As shown, a forced feeding device 9 is installed on the material cylinder 1. The material cylinder 1 has an installation port 8. The forced feeding device 9 includes a housing 901 fixedly connected inside the installation port 8. A conveyor belt 902 is installed inside the housing 901. Multiple arc-shaped claws 903 are fixedly connected to the outer side of the conveyor belt 902 for gripping materials. A second drive motor 904 is fixedly connected to the housing 901, and the output end of the second drive motor 904 is fixedly connected to the input end of the conveyor belt 902.

[0037] In use, the second drive motor 904 provides power to drive the conveyor belt 902 and the arc-shaped claw 903 to operate. The arc-shaped claw 903 can stably grasp the lemons and force them to move downwards to ensure that the lemons can be fed and the production is uniform.

[0038] Furthermore, such as Figure 1 , Figure 2 As shown, a base 13 is provided at the bottom of the material cylinder 1, and an installation groove is provided on the base 13. Both the material cylinder 1 and the pressing cylinder 5 are installed inside the installation groove. Both the material cylinder 1 and the pressing cylinder 5 are fixedly connected to a discharge pipe 11, and a control valve 12 is provided on each discharge pipe 11. Two placement slots 14 are provided on the base 13, and both placement slots 14 are located below the discharge pipes 11.

[0039] In this embodiment, the base 13 can effectively support the material cylinder 1 and the pressing cylinder 5, preventing them from shaking during operation. The discharge pipe 11 can conveniently and quickly discharge the produced material for subsequent production.

[0040] The usage process of the low-temperature cold-pressing extraction device provided by this utility model is as follows:

[0041] After starting the device, the operator can put the whole lemon to be processed into the device from the feed hopper 10 at the top of the material cylinder 1. At this time, the second drive motor 904 drives the conveyor belt 902 inside the housing 901 to run. The arc-shaped claw 903 on the outside of the conveyor belt 902 can firmly grasp the lemon and stably convey it downward in the material cylinder 1. Then, the lemon will come into contact with the scraper 2 fixed on the inner wall of the material cylinder 1. During the downward movement of the lemon, the scraper 2 can remove its peel. Then, these peels will pass through the drain 3, the outer shell 4 and the connecting shell 6 in sequence and enter the pressing cylinder 5. In the pressing cylinder 5, the pressing component 7 can be used to press it to obtain lemon peel extract.

[0042] In addition, the lemons whose peels have been separated inside the barrel 1 will continue to fall and be extracted by the pressing component 7 at the bottom of the barrel 1. The final material can be discharged through the discharge pipe 11 for subsequent production.
