Description

Technical Field

[0001] The utility model relates to the technical field of refined processing of polygonatum, and particularly relates to a refined processing system for polygonatum. Background Art

[0002] Polygonatum is a Chinese medicinal material with both medicinal and edible properties, and its fruit has attracted much attention due to its rich nutritional value and medicinal efficacy. As a processed product of polygonatum, polygonatum candied fruit has the advantages of convenient consumption and long shelf life. However, there are certain challenges in taste and eating experience, mainly manifested as problems such as a hard texture, excessive sourness and bitterness, which limit its further promotion and application in the market.

[0003] The preparation process of polygonatum candied fruit usually includes multiple steps such as raw material selection, cleaning, slicing, soaking, cooking, sugar coating, and drying. In traditional processes, the bitterness of polygonatum candied fruit mainly comes from various active ingredients in polygonatum, such as saponins and polyphenols. These ingredients are not easily completely removed or degraded during the preparation of candied fruit, resulting in the taste and flavor of the final product not meeting the expectations of consumers. To solve the problem of the poor taste of polygonatum candied fruit, researchers and enterprises in related fields have carried out a large amount of technical R & D work. For example, Chinese Patent No. 201910567729.X discloses a preparation method of polygonatum candied fruit, which includes cleaning, drying, slicing, steaming, boiling sugar solution, and drying polygonatum. During the boiling of the sugar solution, the sugar solution obtained by boiling water with wolfberries, honey, and red dates is used to boil polygonatum to improve its bitter and sour components. However, the polygonatum product processed in this way has a sweet and greasy taste when eaten, but the bitterness and sourness are not eliminated but only partially masked, and the aftertaste is still relatively bitter. Moreover, the addition of wolfberries, honey, and red dates makes the flavor of the final polygonatum product impure. How to improve the taste and flavor of candied polygonatum without external additives remains a difficult point in research and development.

[0004] In addition, some researchers have tried to reduce the content of bitter substances in candied fruit by optimizing cooking temperature and time, adjusting sugar coating concentration and time, and changing drying conditions, but the effects are not ideal. Some researchers have also improved the flavor of polygonatum candied fruit by improving the candied fruit preparation device. For example, Chinese Patent No. CN217471166U discloses a drying and flavor-enhancing device for producing polygonatum candied fruit, which realizes more sufficient and uniform turning of candied fruit through equipment improvement, improves the drying efficiency of candied fruit while realizing flavor enhancement of candied fruit. However, the prepared polygonatum candied fruit has a hard texture and a relatively strong bitterness. Therefore, the utility model aims to develop a production system for candied polygonatum to produce candied polygonatum products with better taste quality and purer flavor.

Detailed implementation mode

[0028] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0029] As Figure 1 shown, a refined processing system for sauce-flavored yellow essence includes a spreading device 1, a depilation device 2, a rolling device 3, a first steaming device 4, a slicing device 5, a sauce-flavored liquor mixing device 6, and a second steaming device 7 that are sequentially connected by a conveyor belt; in addition, it further includes a first drying device 8, a second drying device 9, and a micro-fermentation device 10.

[0030] The first drying device 8 is respectively connected to the spreading device 1, the depilation device 2 and the rolling device 3 through a conveyor belt; the second drying device 9 is respectively connected to the first steaming device 4, the slicing device 5 and the second steaming device 7 through a conveyor belt; the micro-fermentation device 10 is respectively connected to the depilation device 2 and the second drying device 9 through a conveyor belt. In the path that needs to be reciprocally conveyed, a reciprocating conveyor belt can be selected for the conveyor belt, so as to save costs and achieve more efficient processing and production at the same time. In some other preferred embodiments, it can also be changed from being connected by a conveyor belt to being arranged close to each other. This setting can reduce the equipment construction cost, but to a certain extent, it is not conducive to the improvement of production efficiency.

[0031] The spreading device 1 is a multi-layer spreading device, which is mainly used for natural withering of the yellow essence raw material or cooling and timely heat dissipation of the yellow essence during the processing process, so as to prevent the growth of bitter taste substances caused by the yellow essence piling up.

[0032] The depilation device 2 is a drum-type depilation device; as Figure 2As shown, the hair removal device 2 includes a drum sieve 21. A plurality of reinforcing guard plates 22 are circumferentially spaced inside the drum sieve 21. The extending direction of the reinforcing guard plates 22 is consistent with the length direction of the drum sieve 21. Short pointed teeth are provided on the inner surface of the reinforcing guard plates 22. The short pointed teeth are preferably conical teeth, protruding 2-3 mm inside the inner side of the reinforcing guard plates 22. Thus, during the hair removal process, it can more conveniently remove the miscellaneous whiskers and even the epidermis on the surface and in the grooves of the fresh polygonatum, and can cut tiny tooth grooves on the surface of the fresh polygonatum during the rotational hair removal process, which is beneficial to saccharification.

[0033] The rolling and kneading device 3 includes a rolling and kneading machine, as Figure 3 shown. A rotating rolling and kneading cavity 31 is provided inside the rolling and kneading machine. A plurality of large rolling and kneading rollers 32 and small rolling and kneading rollers 33 are dispersedly arranged inside the rolling and kneading cavity 31. The large rolling and kneading rollers 32 and the small rolling and kneading rollers 33 are staggeredly arranged. Through the staggeredly arranged large rolling and kneading rollers 32 and small rolling and kneading rollers 33, the polygonatum after hair removal treatment can be more fully and multi-levelly rolled and kneaded inside the rolling and kneading device 3, so as to better promote saccharification. And during the rolling and kneading process, due to the existence of tooth grooves on the surface of the polygonatum, it can further facilitate molecular movement, thereby reducing the bitter taste and improving the taste. During the test process, when there are no tooth grooves on the surface of the polygonatum, only simple hair removal is carried out and a traditional tea rolling machine is used for processing, then the bitter taste at the position close to the center of the prepared polygonatum is still relatively obvious, indicating that the saccharification is uneven and insufficient.

[0034] The first drying device 8 is an open-type oven structure. The first drying device 8 includes an oven, as Figure 4 shown. The top of the oven is open. A support plate 81 with ventilation holes is provided in the middle of the oven. The baking part 82 is above the support plate 81, and the hot air circulation part 83 is at the bottom of the support plate 81. One end of the hot air circulation part 83 is provided with an air inlet 85 and an air outlet 86. Both the air inlet 85 and the air outlet 86 are connected to an external hot air generating device 84. This open-type oven structure is particularly important in the production and processing of fermented polygonatum. The hot air enters through the bottom and slowly diverges upward through the ventilation holes on the support plate 81. At a relatively low temperature, the polygonatum emits its own moisture while fully contacting the air and slowly saccharifies. This process can prevent the phenomenon of acidification caused by premature drying of the polygonatum in a closed environment to a certain extent, and further ensure the taste of fermented polygonatum.

[0035] The second drying device 9 is a commonly used closed-type drying device, which is used to quickly dehydrate the product in the later stage of fermented polygonatum processing.

[0036] The micro-fermentation device 10 is a closed-type fermentation device. In this embodiment, the micro-fermentation device 10 can be a closed tank with a cover.

[0037] The Jiangjiu mixing device 6 includes a mixing chamber, which is connected to a negative pressure generating device. Thus, in the later stage of mixing, a negative pressure can be formed in the mixing chamber through the negative pressure generating device, which is conducive to the full and uniform penetration of Jiangjiu into the interior of polygonatum sibiricum, and can better facilitate the dissolution of bitter and astringent taste substances in polygonatum sibiricum, further improving the taste of the product.

[0038] The slicing device 5 is a pressing and slicing device. The slicing device 5 includes a frame 51, a receiving groove 52 provided on the frame 51. The receiving groove 52 is open at the top and is used to place the polygonatum sibiricum product to be pressed and cut. A liftable pressing device 53 is provided above the receiving groove 52. As Figure 5 described, the pressing device 53 includes a pressing plate 532, and the pressing plate 532 is adapted to the receiving groove 52 to ensure that it can be pressed into the receiving groove 52 and completely cover the polygonatum sibiricum raw material in the receiving groove 52. The pressing plate 532 has a certain thickness, so as to prevent deformation during the pressing process. Preferably, the pressing plate 532 is a stainless steel pressing plate 532, and the pressing plate 532 is horizontally arranged. As an improvement, anti-slip grooves are provided at the bottom of the pressing plate 532, and anti-slip grooves are also provided on the surface of the movable push plate 54 to reduce the relative sliding between the medicinal materials after downward pressure is applied, further improving the stability of cutting. The top of the pressing plate 532 is connected to a push-pull cylinder 531, and it moves up and down under the drive of the push-pull cylinder 531. In order to further improve the stability of the push-pull cylinder 531 driving the pressing plate 532 to move up and down, guide rods 533 are provided on both sides of the push-pull cylinder 531, and the guide rods 533 pass through the guide holes on the frame 511 and are connected to the pressing plate 532. As Figure 6 shown, a movable push plate 54 is provided at the bottom of the receiving groove 52, and a scraper 541 is provided on the surface of the movable push plate 54. The scraper 541 forms a certain angle with the pushing and pulling direction of the movable push plate 54; in a preferred solution, the scraper 541 is perpendicular to the pushing and pulling direction of the movable push plate 54, so that during the repeated pushing and pulling of the movable push plate 54, the bottom of the Chinese medicinal material is scraped by the scraper 541 to obtain stable thin slices. As an improvement to this embodiment, as Figure 7 shown, the longitudinal section of the cutting knife is a triangular structure, preferably an isosceles triangular structure, so that the structure is more solid and the durability is higher. As a further improvement to this embodiment, the scraper 541 can be detachably and fixedly connected to the surface of the movable push plate 54, for example, fixed connection through a bolt assembly. As Figure 6 shown, a blanking port 543 is provided adjacent to the scraper 541. The width of the blanking port 543 and the scraper 541 is adapted to the receiving groove 52. Therefore, the polygonatum sibiricum at the bottom of the receiving groove 52 can be cut layer by layer, and the sliced pieces after cutting are discharged in time through the blanking port 543, reducing the extrusion or mixing between the polygonatum sibiricum slices and the polygonatum sibiricum raw material to be cut, further reducing the broken material rate and improving the yield rate. The width of the blanking port 543 needs to allow the thin slices to pass through but not allow the polygonatum sibiricum raw material to be cut to pass through. In actual operation, as a further improvement to this embodiment, as Figure 6As shown in the figure, an adjusting plate 542 can be arranged adjacent to the blanking port 543. The adjusting plate 542 is detachably and fixedly connected to the movable push plate 54, so that the width of the blanking port 543 can be adjusted as required. A discharge chute 56 is arranged at the bottom of the blanking port 543. The discharge chute 56 is inclined, so that the cut Chinese herbal medicine slices can be discharged in time to prevent accumulation. As Figure 5 shown, the movable push plate 54 is horizontally arranged. The movable push plate 54 is connected to the crank and connecting rod mechanism 55. Guide grooves with lateral openings are arranged on both sides of the frame 511. The movable push plate 54 slides horizontally back and forth along the guide grooves driven by the crank and connecting rod mechanism 55. Since the irregular-shaped polygonatum sibiricum is pressed by the pressing device 53 and is in a state where it cannot move relative to each other and is tense, therefore, during the sliding process of the bottom scraper 541, the Chinese herbal medicine can be cut more stably and evenly. After cutting, it is discharged through the discharge port in time, further reducing the generation of debris. And because the cut polygonatum sibiricum slices are thin, stable, uniform, and have less debris, they can form a stable taste better during subsequent processing in the sauce wine mixing device 6, the second steaming device 7, and the second drying device 9, preventing uneven thickness, being difficult to control as a whole, and causing the phenomenon that some of the sauce polygonatum sibiricum products have a good taste while the rest of the sauce polygonatum sibiricum products still have a bitter taste and a poor softness of the taste.
