Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a device for synergistically blocking the formation of ash smoke by combining biological enzymes and microbial agents. Background Technology

[0002] Ash residue is an undesirable phenomenon that occurs during tobacco processing and combustion. It mainly manifests as a grayish-black deposit remaining on the surface of the tobacco or after combustion. This process is accelerated by high temperature, high humidity, and alkaline environments during tobacco processing, such as drying and fermentation. The formation of ash residue is primarily caused by polyphenol oxidase (PPO) catalyzing the oxidation of phenolic substances into quinone compounds, which then polymerize, severely affecting the appearance of the tobacco leaves and the quality of combustion. In existing technologies, chemical inhibitors such as cysteine ​​block the reaction by chelating copper ions at the active site of PPO, but this poses a risk of chemical residue and is easily inactivated at high temperatures. For example, Chinese Patent Publication No. CN117814514A, entitled "A Composition, Method and Application for Reducing Ash on Tobacco Leaves," uses a composition of gentianic acid and 4-hexylresorcinol to inhibit polyphenol oxidase activity through synergistic effects, thereby reducing ash on tobacco leaves. However, the compound 4-hexylresorcinol poses a risk of chemical residue and its dosage needs to be strictly controlled. While single biological methods such as laccase or lactic acid bacteria are environmentally friendly, their enzyme stability is poor and the survival rate of the bacterial agents is low, making it difficult to effectively inhibit PPO activity for a long time in high-temperature and high-humidity environments. In addition, the uneven temperature and humidity control and complex multi-step operations in traditional processes further exacerbate the problems of ash generation and energy consumption.

[0030] refer to Figure 1 This utility model provides a device for synergistically blocking the formation of ash smoke using biological enzymes and microbial agents, comprising:

[0031] The smoke loading chamber 1, heating chamber 2, and rain shelter 3 are arranged adjacent to each other and covered by a shared rain shelter 3.

[0032] The smoke loading chamber 1 includes a material rack 11, a guide plate 12, a bio-enzyme treatment module 13, a microbial agent treatment module 14, and a data acquisition module (not shown in the figure). The material rack 11 divides the smoke loading chamber 1 into multiple layers of space. The bio-enzyme treatment module 13 and the microbial agent treatment module 14 are located at the top of the smoke loading chamber 1.

[0033] Specifically, the material rack 11 includes multiple horizontal supports and multiple vertical supports that are fixedly connected to each other. The horizontal supports are used to place tobacco leaves, and the vertical supports are used to support the horizontal supports.

[0034] The biological enzyme treatment module 13 includes a first sprayer 131 and a first control unit 132. The first sprayer 131 and the first control unit 132 are connected in a controllable manner. The first sprayer 131 is used to spray polyphenol oxidase inhibitors under the control of the first control unit 132. The first control unit 132 is used to adjust the spraying amount and spraying frequency of the first sprayer 131.

[0035] The microbial agent treatment module 14 includes a second sprayer 141 and a second control unit 142. The second sprayer 141 and the second control unit 142 are connected in a controllable manner. The second sprayer 141 is used to spray microbial agents under the control of the second control unit 142. The second control unit 142 is used to adjust the spraying volume and spraying frequency of the second sprayer 141.

[0036] refer to Figure 2 The bottom of the sprayer includes multiple nozzles arranged in parallel to evenly spray polyphenol oxidase inhibitors or microbial agents.

[0037] For example, by spraying polyphenol oxidase inhibitors onto the surface of tobacco leaves through the bio-enzyme treatment module 13, the generated quinone intermediates can be directly removed. For example, laccase converts quinones into colorless products through redox reactions, blocking the pigment deposition path. The microbial agent treatment module 14 sprays microbial agents onto the surface of tobacco leaves, competitively consuming phenolic substrates or secreting inhibitory factors to inhibit PPO activity for a long time. The combination of the "immediate blocking" of bio-enzymes and the "long-term inhibition" of microbial agents forms a synergistic effect, which can more efficiently and stably block the path of tobacco ash formation, reduce the occurrence of tobacco ash, adapt to high temperature and high humidity environments, facilitate subsequent tobacco curing, and is a fully bio-based material with no risk of chemical residues.

[0038] The data acquisition module includes temperature sensors, humidity sensors, and wind speed sensors arranged at multiple locations within the tobacco loading chamber 1. These sensors are electrically connected to a host computer (not shown in the figure) to transmit the collected data. For example, the temperature sensors monitor the indoor temperature distribution in real time, the humidity sensors monitor the indoor humidity distribution in real time, and the wind speed sensors monitor the wind speed at the air inlet in real time. The host computer receives the collected temperature, humidity, and wind speed data, displays and records them in real time, dynamically analyzes the changes in the physicochemical properties of the tobacco leaves and the rate of ash accumulation during the curing process, and further generates control signals based on the analyzed data by running a control algorithm and sending them to the control module.

[0039] The heating chamber 2 includes a closed dehumidifying heat pump unit 21, an axial flow fan 22, and a control module (not shown in the figure). The closed dehumidifying heat pump unit 21 and the axial flow fan 22 are connected to the control module. The closed dehumidifying heat pump unit 21 includes a heating module and a humidity control module.

[0040] Specifically, the heating module is an electric heater, which is connected to the control module for adjusting the heating temperature under the control of the control module. Preferably, an electric heater with a power of 2kW, a temperature range of 30~80℃, and an accuracy of ±1℃ is selected.

[0041] The humidity control module includes an ultrasonic humidifier and a condenser dehumidifier. The ultrasonic humidifier and the condenser dehumidifier are connected to the control module and are used to adjust the air humidity under the control of the control module. Preferably, an ultrasonic humidifier with a humidity range of 30~90%RH and an accuracy of ±5% is selected to adjust the humidity of the tobacco loading chamber. The ultrasonic humidifier atomizes water through high-frequency vibration and diffuses it into the air to quickly increase the humidity and ensure that the tobacco leaves maintain appropriate moisture in the early stage of baking to avoid cracking. The condenser dehumidifier cools the air to condense and discharge the moisture, controls humidity fluctuations, and prevents moisture from accumulating on the surface of the tobacco leaves in a high-temperature and high-humidity environment.

[0042] An axial flow fan 22 is installed at the top of the heating chamber 2. The axial flow fan 22 is connected to the control module and is used to adjust the wind speed under the control of the control module. Preferably, the wind speed range is 0.5-2.5 m / s. Combined with the guide plate 12, it guides the air flow path and works with the heating module and humidity control module to ensure that the temperature and humidity distribution in the tobacco loading chamber 1 is consistent. This avoids uneven heating of tobacco leaves or moisture accumulation caused by local high temperature and high humidity, thereby reducing the local conditions for the formation of tobacco ash. At the same time, it avoids excessive wind speed from causing the loss of microbial agents on the surface of tobacco leaves.

[0043] An air inlet 4 is provided at the top of the shared wall between the smoke loading chamber 1 and the heating chamber 2, and a return air inlet 5 is provided at the bottom of the shared wall. Guide plates 12 are respectively provided at the angle between the side plate at the far end of the air inlet in the smoke loading chamber 1 and the top and bottom plates, forming a closed-loop airflow channel from above the axial flow fan 22 of the heating chamber 2 through the air inlet 4 into the smoke loading chamber 1 and then through the return air inlet 5 back to below the axial flow fan 22 of the heating chamber 2. The axial flow fan 22, in combination with the heating module and the guide plates 12, drives hot air into the smoke loading chamber 1 through the air inlet 4 to bake the tobacco leaves. The evaporated moisture in the tobacco leaves and the hot air flow back to the heating chamber 2 through the return air inlet 5. The air is cooled by the condenser dehumidifier, and the moisture is condensed and discharged. This achieves convective heat exchange between the smoke loading chamber 1 and the heating chamber 2.

[0044] The side panels and top panel of the smoke loading chamber 1 and the heating chamber 2 are made of stainless steel, and the inner walls of the side panels and top panel are covered with heat insulation material.

[0045] In summary, this invention, by setting up a biological enzyme treatment module and a microbial agent treatment module, sprays polyphenol oxidase inhibitors and microbial agents onto the surface of tobacco leaves to doubly block the formation path of tobacco ash, leaving no chemical residues. It is suitable for the high-temperature and high-humidity tobacco processing environment. Combined with a data acquisition module, a sealed dehumidifying heat pump unit, and an axial flow fan, it optimizes airflow, dynamically adjusts environmental parameters, and optimizes the blocking efficiency. This invention can efficiently, stably, and environmentally prevent the generation of tobacco ash.

[0046] The above description is merely a preferred embodiment of this utility model. Those skilled in the art should understand that the scope of disclosure involved in this utility model is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalent features without departing from the above-described concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this utility model.
