Description

Technical Field

[0001] This utility model relates to the field of areca nut processing technology, specifically to a vacuum pressurization mechanism for areca nut processing. Background Technology

[0002] Areca nut contains a variety of nutrients and beneficial substances needed by the human body, as well as a variety of pharmacologically active ingredients, mainly including alkaloids, phenolic compounds, fatty oils, various amino acids, and a variety of minerals. The traditional processing of areca nut involves multiple cycles of "moistening, pickling, steaming, and sun-drying," among which the moistening and pickling stages directly affect the product's softness, flavor retention, and subsequent microbial safety.

[0003] Existing pickling equipment mostly uses atmospheric pressure soaking or simple vacuum soaking tanks: atmospheric pressure soaking takes more than ten hours, and the difference in moisture content between the surface and the core is large, which easily results in a soft outer skin and a hard core that has not been penetrated; although simple vacuum soaking tanks can shorten the time, when vacuuming, the volatile essential oils and a large amount of water vapor in the areca nut enter the pump body with the airflow, which not only causes the loss of aroma, but also causes pump oil emulsification and valve plate corrosion. Moreover, only a single steam or single compressed air is set up, and the humidity cannot be adjusted online, often resulting in two extremes: "overly wet and rotten pieces" or "dry and hard pieces with insufficient rehydration". Utility Model Content

[0004] The purpose of this invention is to provide a vacuum pressurization mechanism for processing areca nuts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum pressurization mechanism for processing areca nuts, comprising: A variable pressure artillery canister, comprising a canister body and a canister cover, wherein the canister body is provided with an inner cavity and a jacketed outer cavity; A vacuum assembly, comprising a vacuum pump, a vacuum solenoid valve, a vacuum check valve, a gas-liquid separator, a vacuum buffer tank, and a condenser connected in sequence via pipes, wherein the inlet end of the condenser is connected to the gas outlet end at the top of the tank cover; A pressurization assembly, comprising a steam branch, a compressed air branch, and a mixing branch, wherein the steam branch and the compressed air branch are connected in parallel to the mixing branch, and the mixing branch comprises a tee connector, a proportional regulating valve, and a sterilizing filter connected in sequence via pipes, wherein the output end of the sterilizing filter is connected to the air inlet end at the top of the tank lid; The controller is electrically connected to the various electrical devices within the vacuum assembly and the pressurization assembly.

[0006] Furthermore, the steam branch includes a saturated steam source, a manual steam shut-off valve, a steam electric ball valve, and a steam check valve connected in sequence through a pipeline. The steam check valve is connected to a three-way connector. The saturated steam source provides stable and clean saturated steam. The steam check valve prevents high-pressure gas or liquid from backflowing into the steam pipeline. The manual steam shut-off valve can immediately cut off the steam during installation, maintenance, or emergency power outages to ensure the safety of personnel and equipment.

[0007] Furthermore, the compressed air branch includes an oil-free air compressor, a pressure reducing valve, an electric compressed air ball valve, and a compressed air check valve connected in sequence via pipelines. The compressed air check valve is connected to a three-way connector. The oil-free air compressor provides a clean air source, the pressure reducing valve stabilizes the high-pressure air to the target value, and works in conjunction with the steam proportional regulating valve. The compressed air check valve can prevent high-pressure steam from backflowing to the compressed air side, protecting the oil-free air compressor from high-temperature impact.

[0008] Furthermore, a pressure sensor and a temperature sensor are installed on the inner wall of the can lid. The pressure sensor and the temperature sensor are electrically connected to the controller and monitor the air pressure and temperature inside the can.

[0009] Furthermore, the tank cover is equipped with a pressure relief pipe and an installation valve, which can quickly break the vacuum or release excess pressure in an emergency to prevent material from being sprayed out when the cover is opened or the tank body from being deformed due to overpressure.

[0010] Furthermore, the variable pressure processing tank is equipped with a stirring assembly, which includes a rotating shaft installed inside the tank and a geared motor installed on the tank cover. The output end of the geared motor passes through the tank cover and is connected to the rotating shaft. Stirring paddles are fixed on the bottom of both sides of the rotating shaft. The geared motor is electrically connected to the controller. When the geared motor works, it drives the stirring paddles to rotate, which can continuously turn the areca nuts, so that the surface of the areca nuts is in uniform contact with the pickling liquid.

[0011] Furthermore, the condenser is located above the tank cover. The condenser liquefies condensable vapors in advance, reduces pump load, and recovers aromatic / active ingredients. The condensed liquid can flow back into the variable pressure brewing tank by gravity.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By incorporating vacuum and pressurization components, it can achieve flexible switching between negative and positive pressure. During the negative pressure stage, air between areca nut cells is quickly removed to form an initial "channel". During the positive pressure stage, the mixture of steam and compressed air is allowed to penetrate in, achieving uniform wetting or instantaneous sterilization. 2. After the steam branch and the compressed air branch are connected in parallel, the mass flow rate of the two gases is adjusted in real time by the proportional regulating valve. The steam provides moisture and heat, and the compressed air provides adjustable oxygen concentration and elastic pressure. The high-temperature mixed airflow completes surface and shallow sterilization while penetrating, which significantly reduces the risk of subsequent mold growth. 3. By installing a condenser in the vacuum assembly, with the inlet end of the condenser connected to the outlet end at the top of the lid, the aromatic condensate recovered by the condenser can be recycled during vacuuming, reducing aroma loss.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1 to 4 The vacuum pressurization mechanism for processing areca nuts shown includes: The variable pressure artillery can 10 includes a can body 11 and a can cover 12. The can body 11 is provided with an inner cavity and a jacketed outer cavity. Vacuum assembly 20 includes a vacuum pump 21, a vacuum solenoid valve 22, a vacuum check valve 23, a gas-liquid separator 24, a vacuum buffer tank 25, and a condenser 26 connected in sequence by pipes. The inlet end of the condenser 26 is connected to the gas outlet end at the top of the tank cover 12. The pressurization assembly 30 includes a steam branch 31, a compressed air branch 32, and a mixing path 33. The steam branch 31 and the compressed air branch 32 are connected in parallel to the mixing path 33. The mixing path 33 includes a tee joint 331, a proportional regulating valve 332, and a sterilizing filter 333 connected in sequence through pipes. The output end of the sterilizing filter 333 is connected to the air inlet end at the top of the tank cover 12. The controller is electrically connected to the various electrical devices within the vacuum assembly 20 and the pressurization assembly 30.

[0018] The steam branch 31 includes a saturated steam source 311, a manual steam shut-off valve 312, a steam electric ball valve 313, and a steam check valve 314 connected in sequence through a pipeline. The steam check valve 314 is connected to a three-way connector 331. The saturated steam source 311 provides stable and clean saturated steam. The steam check valve 314 prevents high-pressure gas or liquid from backflowing into the steam pipeline. The manual steam shut-off valve 312 can immediately cut off the steam during installation, maintenance, or emergency power outages to ensure the safety of personnel and equipment.

[0019] The compressed air branch 32 includes an oil-free air compressor 321, a pressure reducing valve 322, a compressed air electric ball valve 323, and a compressed air check valve 324 connected in sequence via pipelines. The compressed air check valve 324 is connected to a three-way connector 331. The oil-free air compressor 321 provides a clean air source. The pressure reducing valve 322 stabilizes the high-pressure air to the target value and works in conjunction with the steam proportional regulating valve. The compressed air check valve 324 can prevent high-pressure steam from backflowing to the compressed air side and protect the oil-free air compressor 321 from high-temperature impact.

[0020] Pressure and temperature sensors are installed on the inner wall of the can lid 12. The pressure and temperature sensors are electrically connected to the controller. The pressure and temperature sensors monitor the air pressure and temperature inside the can 11 and provide real-time feedback on the cavity status.

[0021] The can lid 12 is equipped with a pressure relief pipe 13, and an installation valve 14 is installed on the pressure relief pipe 13. In an emergency, the vacuum can be quickly broken or excess pressure can be released to prevent material from being sprayed out when the lid is opened or the can body 11 from being over-pressured and deformed.

[0022] The condenser 26 is located above the tank cover 12. The condenser 26 liquefies condensable vapors in advance, reduces pump load, and recovers aromatic / active ingredients. The condensed liquid can flow back into the variable pressure blasting tank 10 by gravity.

[0023] In this utility model, the controller is electrically connected to the vacuum pump 21, vacuum solenoid valve 22, proportional regulating valve 332, saturated steam source 311, steam electric ball valve 313, oil-free air compressor 321, pressure reducing valve 322, compressed air electric ball valve 323, pressure sensor and temperature sensor, etc. The controller adopts an industrial control computer to uniformly collect signals such as temperature, pressure, valve position, motor speed, etc., and drive the vacuum pump 21, each solenoid valve, electric ball valve, proportional regulating valve 332 and geared motor according to the preset program to realize fully automatic cycle. The tank cover 12 is provided with a feed port (not shown), and the bottom of the tank body 11 is provided with a discharge pipe with a discharge valve. During operation, the areca nut material is added into the inner cavity of the variable pressure processing tank 10 through the feed inlet, and the feed inlet is closed, with all valves in the safe initial position; The controller controls the vacuum pump 21 to work. The air and material gap gas in the inner cavity of the variable pressure canister 10 are discharged by the vacuum pump 21 through the air outlet of the canister cover 12, the condenser 26, the vacuum buffer tank 25, the gas-liquid separator 24, the vacuum check valve 23, and the vacuum solenoid valve 22. The gas pressure in the variable pressure canister 10 gradually decreases. The condensable volatile oil and water vapor are condensed into liquid in the condenser 26 and flow back into the variable pressure canister 10 by gravity. Once the set vacuum level is reached inside the variable pressure processing tank 10, the vacuum solenoid valve 22 closes, the vacuum check valve 23 prevents backflow, and the air between the material cells is fully extracted to form a "low-pressure channel" in preparation for subsequent rapid re-dissolution and penetration. The controller starts the pressurization component 30, the steam branch 31 outputs saturated steam, and the compressed air branch 32 outputs clean compressed air. The two air streams converge at the three-way connector 331 and are dynamically mixed by the proportional regulating valve 332 according to the process requirements. The mixed gas is sterilized and particle-removed by the sterilization filter 333 and enters the inner cavity of the tank body 12 through the air inlet end of the can cover 11. As the gas is continuously injected, the pressure in the inner cavity of the tank body 12 gradually increases. The moisture and heat in the mixed gas quickly penetrate into the interior of the areca nut along the "low-pressure channel" to complete the softening, moistening or instantaneous sterilization. Once the target pressure is reached, the proportional control valve 332 enters the fine-tuning mode to maintain a stable positive pressure inside the tank, and the agitator continues to operate at a low speed to ensure a consistent temperature and humidity distribution in the material layer. After the process is completed, the installation valve 14 on the pressure relief pipe 13 is opened, and the pressure inside the can 12 is quickly released to normal pressure. The sudden drop in pressure causes the micropores inside the areca nut to expand, which is beneficial for subsequent drying or sugar and fragrance infusion processes. Depending on the process requirements, the controller can control repeated vacuuming and pressurization several times.

[0024] After the vacuum holding period ends, the proportional regulating valve 332 introduces a mixture of steam and compressed air according to the formula ratio, and the pressure inside the variable pressure processing tank 10 rises rapidly. Under the action of positive pressure and heat, the processing liquid is forced to penetrate into the expanded intercellular spaces, completing rapid pickling, softening and sterilization. After the final step, the installation valve 14 is opened, and the pressure in the variable pressure processing tank 10 returns to normal, and the stirring continues. After processing is completed, the discharge valve is opened, allowing the areca nuts and processing liquid in the variable pressure processing tank 10 to be discharged through the discharge pipe.

[0025] like Figure 1 As shown, the variable pressure tandem grinding tank 10 is equipped with a stirring assembly, which includes a rotating shaft installed inside the tank body 11 and a geared motor installed on the tank cover 12. The output end of the geared motor passes through the tank cover 12 and is connected to the rotating shaft. Stirring paddles are fixed on the bottom of both sides of the rotating shaft. The geared motor is electrically connected to the controller. When the geared motor works, it drives the stirring paddles to rotate, which can continuously turn the areca nuts, so that the surface of the areca nuts is in uniform contact with the pickling liquid.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
