Description

Technical Field

[0001] This utility model belongs to the field of medicinal material processing and preparation technology, specifically, it relates to a steaming device for processing Polygonatum sibiricum. Background Technology

[0002] Polygonatum sibiricum, first recorded in the *Shennong Bencao Jing* (Shennong's Classic of Materia Medica), was included in the "List of Food and Medicine with the Same Origin" in 2014. The medicinal part is the dried rhizome of *Polygonatum kingianum* Coll. et Hemsl., *Polygonatum sibiricum* Red., and *Polygonatum cyrtonema* Hua, all belonging to the Liliaceae family. The main chemical components of Polygonatum are polysaccharides, saponins, flavonoids, and anthraquinones. Modern pharmacological studies have found that Polygonatum possesses various pharmacological activities, including regulating blood sugar, lowering blood lipids, and antibacterial and anti-inflammatory effects. Furthermore, the thick rhizome of Polygonatum is rich in nutrients such as starch, polysaccharides, proteins, amino acids, and vitamins, and is often used in cooking or as a raw material in health supplement formulations.

[0003] Raw Polygonatum has mild toxicity and can easily cause numbness of the mouth and tongue, requiring processing to reduce toxicity and enhance efficacy. Current research on the processing of Polygonatum focuses primarily on its medicinal applications, with relatively less research on its edible uses. The different applications for food and medicine lead to varying requirements for the quality control of raw materials and the application of specific components, resulting in differences in the selection of raw materials. There are significant differences in the edible and medicinal value of different varieties of Polygonatum. Medicinal Polygonatum emphasizes quality requirements such as the quality and composition of the raw material, while edible Polygonatum, in addition to meeting nutritional value requirements, also considers palatability requirements such as taste and texture.

[0004] The main processing methods for Polygonatum include single steaming, double steaming, and wine steaming. As one of the four major nine-steamed products, its main processing method is nine steaming and nine drying, which involves repeatedly steaming and drying Polygonatum. Currently, cooking pots and other containers are commonly used when steaming Polygonatum. However, fresh Polygonatum will release juice during the steaming process, which drips naturally and is difficult to collect, resulting in a waste of active ingredients. In addition, ordinary cooking pots are relatively cumbersome to operate. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steaming device for processing Polygonatum sibiricum, so as to solve the problems of cumbersome operation of ordinary steaming pots and waste of active ingredients of Polygonatum sibiricum.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steaming device for processing Polygonatum sibiricum, comprising a body and a cover, a control panel embedded in the front side of the body, a water tank in the upper inner part of the body, and an electric heating plate and a thermal switch respectively installed at the bottom of the water tank, the electric heating plate being electrically connected to the control panel through the thermal switch, the cover being snapped onto the water tank, a support ring being provided inside the water tank, and a tray being placed on the support ring, a liquid collection tank being provided at the bottom of the tray, and a perforated pad being provided at the top of the liquid collection tank, a steam channel being provided in the middle of the liquid collection tank, and the steam channel extending above the perforated pad, the trays being stacked on top of each other in pairs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 This utility model designs a steaming device for processing Polygonatum sibiricum. The device includes a body 1 and a cover 2. A control panel 3 is embedded in the front of the body 1. A water tank 4 is provided in the upper part of the body 1, and an electric heating plate 5 and a thermal switch 6 are respectively installed at the bottom of the water tank 4. The electric heating plate 5 is electrically connected to the control panel 3 through the thermal switch 6. The cover 2 is snapped onto the water tank 4. A support ring 7 is provided inside the water tank 4, and a tray 8 is placed on the support ring 7. A liquid collection tank 9 is provided at the bottom of the tray 8, and a perforated pad 10 is provided at the top of the liquid collection tank 9. A steam channel 1 is provided in the middle of the liquid collection tank 9. 1; The steam channel 11 extends above the perforated pad 10, and the trays 8 are stacked on top of each other in pairs; the trays 8 containing Polygonatum are stacked on the support ring 7, pure water is added to the water tank 4, the cover 2 is covered, and the pure water is heated by the electric heating plate 5 to generate steam. An external heating steaming space can be formed between the cover 2 and the trays 8, while the steam channel 11 in the trays 8 can form an internal heating steaming space, which is beneficial to improve the steaming efficiency and is easy to operate. During the steaming process, the juice extracted by Polygonatum drips through the perforated pad 10 into the liquid collection tank 9, which is convenient to collect after the steaming is completed.

[0019] Specifically, the bottom of the cover 2 is provided with an annular groove 12, and it is snapped onto the water tank 4 through the annular groove 12. In this embodiment, the annular groove 12 is a connecting structure used for the assembly between the cover 2 and the water tank 4.

[0020] Specifically, a sealing ring 13 is installed in the annular groove 12, and the sealing ring 13 is located between the annular groove 12 and the top of the water tank 4. In this embodiment, the sealing ring 13 is a device for preventing liquid or gas leakage, usually made of elastic material, which prevents the medium from leaking into the external environment by filling the gap at the joint, thus avoiding pollution and energy waste.

[0021] Specifically, the top of the cover 2 is provided with an interface 14, and an exhaust valve 15 is installed on the interface 14. In this embodiment, the interface 14 is a connection structure, and the main function of the exhaust valve 15 is to discharge the gas generated inside the cover 2 during the heating process, so as to ensure that the internal pressure is not too high and to avoid safety problems.

[0022] Specifically, the support ring 7 has openings 16 around its perimeter, corresponding to the steam channels 11 on the tray 8. In this embodiment, the openings 16 are used to open up the space inside the support ring 7, allowing pure water to circulate between the inside and outside of the support ring 7.

[0023] Specifically, the bottom of the tray 8 is provided with a positioning groove 17, and the trays 8 are interlocked together in pairs through the positioning groove 17. In this embodiment, the positioning groove 17 is an assembly structure used to allow the trays 8 to be stacked together in pairs.

[0024] After being harvested, Polygonatum sibiricum usually needs to be dried for more than a week until it is 70-80% dry. Then it is washed, the roots are removed, and it is processed. Raw Polygonatum sibiricum has a pungent taste in the throat and is not suitable for direct consumption. It needs to be processed into "processed Polygonatum sibiricum" to eliminate the numbing taste. The steaming device provided by this utility model can process raw Polygonatum. In use, a tray 8 containing fresh Polygonatum is stacked on a support ring 7, pure water is added to a water tank 4, and a cover 2 is placed on top. The pure water is heated by an electric heating plate 5 to generate steam. The thermal switch 6 (model KSD301) is usually designed to disconnect the circuit at high temperatures, thereby cutting off the power supply to the heating element. That is, when there is no water or insufficient water in the water tank 4, the heating element directly heats the air, causing the temperature to rise sharply. The thermal switch 6 will disconnect after sensing the high temperature and stop heating. An external heating steaming space can be formed between the cover 2 and the tray 8, while the steam channel 11 in the tray 8 can form an internal heating steaming space, which is beneficial to improving the steaming efficiency and is easy to operate. During the steaming process, the juice extracted from Polygonatum drips through the perforated pad 10 into the collection tank 9, which is convenient to collect after steaming.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
