Description

Technical Field

[0001] This utility model relates to the field of gas control technology, and in particular to a device for controlling the growing atmosphere of organic food. Background Technology

[0002] In the cultivation of organic food, intervention is generally carried out by adding growth-promoting agents such as antibiotics, vitamins, gibberellins, and indoleacetic acid. For example, when cultivating bean sprouts, they may grow roots but not stems at a certain stage, at which point artificial growth-promoting agents need to be added to intervene.

[0003] The addition of growth regulators to organic food cultivation can lead to potential food safety issues due to residues. However, this problem can be perfectly solved by controlling the atmospheric conditions of the organic food growing environment (i.e., controlling the concentration of growth regulator gases). Growth regulator gases such as ethylene, as an endogenous plant growth regulator, can be used in processed food products such as sprouts according to national standards. The ethylene residue in these products is not significantly different from that in sprouts produced without ethylene, and therefore does not cause the aforementioned food safety issues.

[0004] In existing technologies, the gas is stored in steel cylinders and the gas flow is controlled by a solenoid valve. However, this method cannot precisely regulate the gas concentration in the growth environment. Therefore, there is an urgent need for an organic food growth atmosphere control device that can precisely regulate the gas concentration. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an organic food growth atmosphere control device that can accurately regulate the gas concentration in the gas-using equipment and replenish gas to the gas-using equipment in real time according to the detection results of the gas concentration analyzer, which can effectively ensure the stability of the internal atmosphere and the consistency of the concentration of the gas-using equipment.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An organic food growth atmosphere control device includes a gas distributor and a gas concentration analyzer. The gas distributor is used to provide growth conditioning gas to the gas-using equipment. The gas inlet of the gas distributor is connected to the growth conditioning gas source. The gas outlet of the gas distributor is provided with multiple outlets and is evenly arranged in the gas-using equipment.

[0008] The gas-using equipment has multiple sampling points inside, which are connected to the inlet of a gas concentration analyzer via pipes. The gas concentration analyzer is used to detect the concentration of growth regulating gas inside the gas-using equipment, and the gas distributor regulates the concentration of growth regulating gas inside the gas-using equipment based on the data from the gas concentration analyzer.

[0009] Furthermore, the gas distributor includes a pressure sensor, a solenoid valve, a gas flow controller, and a check valve arranged in sequence.

[0010] Furthermore, a filter is provided between the pressure sensor and the solenoid valve.

[0011] Furthermore, a dryer is provided between the sampling point and the gas concentration analyzer.

[0012] Furthermore, the gas-using device has a cuboid structure, and the sampling points are located at the four corners of the gas-using device.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figure 1 This utility model provides a technical solution:

[0021] Example:

[0022] like Figure 1As shown, an organic food growth atmosphere control device includes a gas distributor 1 and a gas concentration analyzer 2. The gas distributor 1 is used to provide growth conditioning gas to the gas-using equipment 3. The gas inlet of the gas distributor 1 is connected to the growth conditioning gas source. Multiple gas outlets of the gas distributor 1 are provided and evenly arranged in the gas-using equipment 3.

[0023] The gas-using device 3 has multiple sampling points 4 inside. The sampling points 4 are connected to the gas inlet of the gas concentration analyzer 2 through pipes. A dryer 10 is provided between the sampling points 4 and the gas concentration analyzer 2. The gas concentration analyzer 2 is used to detect the concentration of growth regulating gas inside the gas-using device 3. The gas distributor 1 regulates the concentration of growth regulating gas inside the gas-using device 3 according to the data from the gas concentration analyzer 2.

[0024] The gas distributor 1 includes a pressure sensor 5, a filter 6, a solenoid valve 7, a gas flow controller 8, and a check valve 9 arranged in sequence.

[0025] In this embodiment, the gas-using device 3 has a cuboid structure, and the sampling points 4 are located at the four corners of the gas-using device 3.

[0026] The growth regulating gas source is a steel cylinder containing the growth regulating gas.

[0027] It also includes a PLC, with the signal output terminal of the gas concentration analyzer 2 connected to the signal input terminal of the PLC, and the signal output terminal of the PLC connected to the signal input terminal of the gas flow controller 8.

[0028] In this embodiment, 1. the growth regulating gas is ethylene. 2. the gas-using device 3 can be, but is not limited to, an incubator.

[0029] Working principle: Opening solenoid valve 7 activates gas flow controller 8, allowing ethylene from the cylinder to enter the gas-using device 3. The flow rate of ethylene is adjusted by gas flow controller 8; the higher the flow rate, the faster the ethylene concentration in gas-using device 3 increases. When the ethylene concentration in gas-using device 3 approaches 90%-95% of the target concentration, the flow rate of gas flow controller 8 is reduced, allowing the ethylene concentration in gas-using device 3 to gradually reach the target concentration, thus achieving precise control.

[0030] During the cultivation process, the gas concentration inside the gas-using device 3 gradually decreases. Therefore, sampling points evenly distributed within the device are used to sample the gas inside. The sampled gas is then connected to the gas concentration analyzer 2, allowing for real-time monitoring of the gas concentration inside the device 3. When the concentration inside the device 3 decreases, the solenoid valve 7 and flow controller activate to replenish the gas into the device 3. During this process, the PLC controls the gas distributor 1 to intermittently replenish gas to the device 3 based on the detected values, stopping when the concentration reaches the target and replenishing promptly when the concentration decreases. Furthermore, if the volume of the device 3 varies, the replenishment frequency of the gas distributor 1 is adjusted according to the gas concentration stabilization time.

[0031] This invention can precisely control the gas concentration inside gas-using equipment, and can replenish gas to the equipment in real time based on the detection results of the gas concentration analyzer, effectively ensuring a stable internal atmosphere and consistent concentration within the equipment.
