Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for Platycodon grandiflorus tea, specifically a steaming device for Platycodon grandiflorus tea. Background Technology

[0002] In the industrial production process of Platycodon grandiflorus tea, the steaming process aims to soften the raw material and improve its flavor and pharmacological properties. At present, although equipment such as multi-functional Chinese herbal medicine steamers, drum steamers and Chinese herbal tea steamers can realize the basic steaming function of Platycodon grandiflorus tea, they have significant defects in terms of internal space adjustment.

[0003] Specifically, the internal space of the steaming box is mostly a fixed structure, and the spacing between the trays, the number of layers, and the overall capacity are difficult to adjust, which cannot meet the dynamic changes in the amount of Platycodon grandiflorum tea to be steamed at any given time. When steaming a small amount of Platycodon grandiflorum tea, the fixed space causes the steam to disperse, making it difficult to form an efficient high-temperature environment, which not only prolongs the steaming time but also increases energy consumption. Therefore, we need to propose a steaming device for Platycodon grandiflorum tea. Utility Model Content

[0004] The purpose of this invention is to provide a steaming device for Platycodon grandiflorus tea. By setting up a detachable tray, steam baffle and conveying components, it achieves flexible adjustment of the internal space of the steaming chamber and optimizes the steam flow and conveying, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steaming apparatus for platycodon tea includes: a steaming box with a steam generator fixedly installed at its bottom;

[0007] Several sets of detachable trays are installed inside the steamer, and the top of the uppermost tray is detachably equipped with a steam baffle. A steaming area is reserved between two adjacent sets of trays.

[0008] A conveying assembly is used to pump steam generated by a steam generator to various steaming zones. The two ends of the conveying assembly are connected to the steam chamber and the steam generator, respectively.

[0009] Preferably, the conveying assembly includes a main conveying pipe, the top end of which is fixedly connected to the steam box, the bottom end of which is fixedly connected to the steam generator, and a first pump body is conductively connected to the outer wall of the main conveying pipe.

[0010] Preferably, the system also includes several sets of auxiliary conveying pipes, one end of which is fixedly connected to each of the steaming zones, and the other end of which is fixedly connected to the main conveying pipe.

[0011] Preferably, both the main delivery pipe and the auxiliary delivery pipe are connected to a shut-off valve at their outlet ends.

[0012] Preferably, several sets of mounting plates are fixedly connected to the inner walls of both sides of the steamer, and a mounting groove is opened on one side wall of the mounting plate. Protrusions that are adapted to the mounting grooves are fixedly connected to the inner walls of both sides of the tray, and the protrusions are inserted into the interior of the mounting grooves.

[0013] Preferably, the two ends of the steam baffle are respectively inserted into the interior of the mounting groove.

[0014] Preferably, the top of the tray is fixedly connected to a handle, and the bottom of the tray has several sets of through holes.

[0015] Preferably, an exhaust pipe is fixedly connected to one side wall of the steam oven, one end of the exhaust pipe is connected to each steaming zone, the other end of the exhaust pipe is fixedly connected to a condenser, and a second pump body is conductively connected to the outer wall of the exhaust pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes several detachable trays. When a small amount of Platycodon grandiflorus tea needs to be steamed, the number of trays can be flexibly reduced, and the steam baffle is always placed on top of the uppermost tray. This reduces the internal space of the steamer, making the steam more concentrated and quickly creating a high-temperature environment. This significantly shortens the steaming time and reduces energy consumption. The reserved steaming area between adjacent trays facilitates even steam circulation, ensuring that each layer of Platycodon grandiflorus tea can fully contact the steam, achieving all-round, uniform steaming without dead angles, and effectively guaranteeing the uniformity of Platycodon grandiflorus tea quality.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] A steaming device for Platycodon grandiflorus tea includes: a steaming chamber 1, with a steam generator 2 fixedly installed at its bottom, the two being connected by a flange seal to ensure no leakage in steam transmission; the steam generator 2 has a built-in electric heating tube and a water level sensor, which can monitor in real time and automatically replenish water to ensure a continuous and stable steam supply; several sets of detachable trays 3, all of which are set inside the steaming chamber 1; by integrating the steam generator 2 at the bottom of the steaming chamber 1, the steam transmission path is shortened, heat loss is reduced, and the complexity of the pipeline of the external steam source is avoided, thus achieving the effect of improving energy efficiency and simplifying operation; and a steam baffle 4 is detachably installed on the top of the uppermost tray 3, and a steaming area 5 is reserved between two adjacent sets of trays 3.

[0025] The conveying assembly 6 is used to pump the steam generated by the steam generator 2 to each steaming zone 5. The two ends of the conveying assembly 6 are connected to the steaming box 1 and the steam generator 2 respectively. The protrusions 9 on both sides of the tray 3 are inserted into the mounting grooves 8 of the mounting plate 7 on the inner wall of the steaming box 1 to achieve quick loading and unloading. The steam baffle 4 is directly inserted into the mounting grooves 8 at both ends, covering the top of the uppermost tray 3 to prevent steam from rushing directly. Through the plug-in installation structure, the user can flexibly increase or decrease the number of trays 3 according to the amount of Platycodon grandiflorus tea to be steamed, and use the steam baffle 4 to adjust the steam flow direction, achieving the dual effects of spatial self-adaptation and steaming uniformity.

[0026] The conveying assembly 6 includes a main conveying pipe 601, the top end of which is fixedly connected to the steaming box 1, and the bottom end of which is fixedly connected to the steam generator 2. A first pump body 602 is also connected to the outer wall of the main conveying pipe 601. The assembly also includes several sets of auxiliary conveying pipes 603, one end of which is fixedly connected to each of the steaming zones 5, and the other end of which is fixedly connected to the main conveying pipe 601. Through the hierarchical design of the main and auxiliary pipes and the independent control of the shut-off valve 604, the steam demand of different steaming zones 5 can be precisely adjusted, avoiding local overheating or underheating caused by direct steam in traditional steaming boxes. This achieves the effect of refined steam distribution and consistent steaming quality.

[0027] Both the main conveying pipe 601 and the auxiliary conveying pipe 603 are connected to a shut-off valve 604 at their outlets. Both the main conveying pipe 601 and the auxiliary conveying pipe 603 are designed with insulated sleeves; the inner layer is stainless steel, and the outer layer is wrapped with 50mm thick aluminum silicate insulation cotton. The shut-off valve 604 is an electric ball valve, and the steam flow rate of each steaming zone 5 can be independently adjusted via a PLC control system. The first pump body 602 is a Roots steam pump with a maximum flow rate of 5m³ / h. 3 The steam output per minute is 0.2-0.5 MPa, and the operating pressure is 0.2-0.5 MPa. By setting up multi-stage delivery pipelines and adjustable shut-off valves 604, the steam supply to each layer can be precisely controlled to meet the steaming requirements of different loading capacities.

[0028] Several sets of mounting plates 7 are fixedly connected to the inner walls of both sides of the steam oven 1. A mounting groove 8 is opened on one side wall of the mounting plate 7. A protrusion 9 that matches the mounting groove 8 is fixedly connected to the inner walls of both sides of the tray 3. The protrusion 9 is inserted into the inside of the mounting groove 8.

[0029] The two ends of the steam baffle 4 are respectively inserted into the interior of the mounting groove 8.

[0030] The top of the tray 3 is fixedly connected to a handle 10, and the bottom of the tray 3 is provided with several sets of through holes 11. Through the design of the handle 10 and the through holes 11, users can quickly complete the loading, unloading and cleaning of the tray 3, while ensuring the uniform circulation of steam in the steaming zone 5, thus achieving the effect of convenient operation and improved steaming efficiency.

[0031] A steam outlet pipe 12 is fixedly connected to one side wall of the steam oven 1. One end of the steam outlet pipe 12 is connected to each steaming zone 5, and the other end of the steam outlet pipe 12 is fixedly connected to a condenser 13. A second pump body 14 is connected to the outer wall of the steam outlet pipe 12. Through the steam circulation and condensation recovery system, the waste heat steam after steaming is condensed and recovered, reducing heat waste and reducing humidity fluctuations in the steam oven 1, thus achieving the effects of energy saving, environmental protection and stability of the steaming process.

[0032] Condenser 13 uses a shell-and-tube heat exchanger with circulating cooling water as the cooling medium, and the inlet and outlet temperature difference is controlled at 5-8℃. The second pump 14 uses a water ring vacuum pump to maintain the system negative pressure at -0.02~-0.05MPa. By setting up a condensation recovery system, the system achieves the effects of recovering waste heat from steam, reducing workshop humidity, and preventing pollution caused by direct steam emissions.

[0033] Working principle: The steam generator 2 heats and generates high-temperature steam, which is pumped to the main conveying pipe 601 by the first pump body 602, and then distributed to each steaming zone 5 through the auxiliary conveying pipe 603; the shut-off valve 604 adjusts the steam flow rate according to the number of trays 3 to ensure uniform distribution. Platycodon tea is placed in the tray 3, and the steam penetrates the material layer through the through hole 11 to complete the steaming; the steam baffle 4 prevents the upper layer of steam from rushing directly and optimizes the flow field distribution. The steamed steam enters the condenser 13 through the exhaust pipe 12, and the condensate is recycled. The uncondensed gas is discharged with the assistance of the second pump body 14 to maintain the pressure stability in the steaming box 1. Through steam graded conveying, flow field optimization and waste heat recovery technology, this device realizes the dynamic matching of steaming space and steam flow rate, solves the problems of fixed space, uneven steam and high energy consumption in traditional steaming boxes, and achieves the comprehensive effect of improving the steaming efficiency, quality stability and energy saving and environmental protection of Platycodon tea.

[0034] 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.
