Description

Technical Field

[0001] This utility model relates to the field of tea pressing equipment technology, and in particular to a steam filter chamber for a tea cake press. Background Technology

[0002] The existing Chinese patent CN201910882221.9 discloses an automatic tea cake pressing machine and its working process. This automatic tea cake pressing machine enables loose tea to be automatically pushed into the steam chamber for steaming after entering the receiving chamber of the compression molding device. Afterwards, the loose tea in the steam chamber is automatically pushed into the molding chamber for molding. The whole process is automated and highly efficient.

[0003] However, in actual production, during the process of steam being transported from the boiler to the steaming room, the steam temperature drops by 5-15℃ due to factors such as heat dissipation from the pipes and ambient temperature differences, causing some of the steam to condense into liquid water. This condensate enters the steaming room with the steam and is absorbed by the tea leaves, resulting in excessive moisture content in the tea leaves (actually measured to be 3%-8% higher than the standard value). This, in turn, leads to an increased risk of mold growth, loss of aroma (due to excessive release of volatile substances with moisture), and uneven hardness in the pressed tea cakes, seriously affecting product quality. Summary of the Invention

[0004] The present invention aims to provide a steam filtration chamber to solve the problem of condensation and water separation caused by temperature difference during steam transportation, and to ensure that the steam entering the tea steaming chamber has a stable temperature and meets the moisture content standard, thereby improving the quality of the pressed tea product.

[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: a steam filtration chamber includes a hollow chamber, the chamber being provided with an air inlet and an air outlet communicating with the inner side of the hollow chamber; a second heating component is provided adjacent to the air inlet and the air outlet.

[0006] Furthermore, the air inlet and air outlet are set at a 90° angle.

[0007] Furthermore, the air inlet and outlet are staggered; the height of the air inlet is much lower than the height of the air outlet. This design causes the steam to form a "U-shaped meandering path" within chamber 1, extending the flow distance to 1.5 times that of a straight pipe layout, ensuring sufficient secondary heating time.

[0008] Furthermore, one end of the compartment is sealed with a pressure-shifting plate that can deform in the axial direction.

[0009] Furthermore, the other end of the compartment is equipped with a switch that can be opened and closed.

[0010] Furthermore, the variable plate is arranged in an umbrella shape.

[0011] Furthermore, the perimeter of the compartment is covered with an insulation layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a second heating component to reheat the steam by means of adjacent air inlet and air outlet, so as to ensure that the temperature does not change when entering the tea steaming chamber, and to ensure that the condensation and precipitation caused by temperature changes will not have an impact.

[0013] This invention uses pressure-adjusting plates to automatically adjust the pressure inside the chamber, preventing excessive pressure from causing dangerous incidents. Additionally, a pressure-adjusting plate at the bottom automatically drains any released moisture, effectively preventing the effects of moisture and ensuring that the chamber remains in the optimal softening and pressing state.

[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] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please see the appendix Figures 1 to 2As shown: A steam filtration chamber includes a hollow chamber 1, with an air inlet 2 and an air outlet 3 communicating with the inner side of the hollow chamber 1; a second heating element 4 is provided adjacent to the air inlet 2 and the air outlet 3. This invention uses the second heating element adjacent to the air inlet and the air outlet to reheat the steam, ensuring that the temperature remains unchanged when the steam enters the steaming chamber, thus preventing condensation and precipitation caused by temperature fluctuations.

[0020] In use, the external steam generator is connected to the air inlet 2 through a pipe to introduce steam. Then, the air outlet 3 is connected to the air inlet of the tea steaming chamber through a high-temperature resistant silicone tube (20mm inner diameter). The internal temperature sensor of the tea steaming chamber (accuracy ±0.5℃) is linked with the temperature control module of the second heating component 4: when the temperature of the tea steaming chamber is lower than the set value (such as 95℃), the heating component automatically increases the power; otherwise, it reduces the power, forming a closed-loop temperature control.

[0021] Based on the above embodiment, the air inlet 2 and the air outlet 3 are set at a 90° angle to reduce the space occupied in the tea pressing equipment and facilitate subsequent pipeline connection.

[0022] Based on the above embodiment, the air inlet 2 and the air outlet 3 are staggered; the height of the air inlet 2 is much lower than the height of the air outlet 3. By staggering them, the time that the steam spends in the chamber 1 can be extended, so that the secondary heating has enough time to heat it.

[0023] Based on the above embodiment, one end of the chamber 1 is sealed with a pressure-reducing plate 5 that can deform axially. The pressure-reducing plate 5 (made of 0.3mm thick spring steel) automatically bulges outward to relieve pressure when the internal pressure exceeds 0.2MPa, and resets to a seal when the pressure drops below 0.1MPa. This invention uses the pressure-reducing plate to automatically adjust the internal pressure of the chamber, preventing excessive pressure from causing dangerous incidents.

[0024] Specifically, when testing with Pu-erh tea pressing, the temperature of the second heating component 4 was set to 105℃, and the pressure inside chamber 1 was controlled at 0.15MPa by the pressure transformer 5. After being processed by this filtration chamber, the steam entered the tea steaming chamber to soften the tea leaves for 30 seconds. The moisture content of the pressed tea cake was stabilized at 11%-12% (within the industry standard range), and the uniformity of hardness was improved by 25%.

[0025] Based on the above embodiments, the other end of the compartment 1 is equipped with a variable plate 6 that can be opened and closed.

[0026] Based on the above embodiments, the variable plate 6 is arranged in an umbrella shape, with an openable and closable variable plate at the bottom to automatically drain the precipitated water, which can effectively avoid the influence of water and ensure that it is always in the optimal softening and pressing state. An openable and closable umbrella-shaped variable plate 6 (made of silicone, with an edge contact pressure of 5-8N with the chamber wall) is installed at the other end (bottom) of the chamber 1. When the condensate in the chamber accumulates to more than 50ml, the gravity of the water overcomes the friction between the variable plate 6 and the chamber wall, and the variable plate automatically opens to drain the water. After the drainage is completed, it returns to its original position and seals itself by its own elasticity.

[0027] Based on the above embodiments, the compartment 1 is surrounded by an insulation layer 7 to reduce heat dissipation and effectively ensure that the heat loss rate is controlled within 5%.

[0028] The working principle of this utility model is as follows: Steam enters chamber 1 through air inlet 2. Due to the circuitous path, it first contacts the inner wall of the chamber, and some of the water vapor condenses into liquid water, which settles at the bottom of the chamber. The second heating component 4 reheats the flowing steam, compensating for the temperature to a preset value (105℃) to prevent condensation due to temperature difference after entering the tea steaming chamber. When the condensate reaches a certain amount, the umbrella-shaped pressure plate 6 automatically opens to drain the water, ensuring the dryness of the steam (moisture content ≤3%). The pressure plate 5 adjusts the pressure inside the chamber in real time to maintain stable steam delivery, and the insulation layer 7 reduces heat loss, ensuring system energy efficiency.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments by making some changes or modifications to the above-disclosed technical content without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
