Application of cryogenic liquid oxygen storage tanks in agriculture
1. Aquaculture
- Oxygenation: Liquid oxygen tanks can provide high-purity oxygen for aquaculture, significantly increasing the dissolved oxygen content in the water. For example, the dissolved oxygen in the traditional blower aeration method fluctuates greatly, often below 3 mg/L, resulting in slow growth and poor vitality of fish. After the liquid oxygen tank is used for oxygenation, the dissolved oxygen content can be stably maintained at above 7-9 mg/L, the growth rate of fish is increased by 10%, the vitality is enhanced, the specifications are neat, the disease resistance is improved, the breeding risk is reduced, and the economic benefits are significantly improved.
- Application scenario: Liquid oxygen tanks are suitable for the entire process of aquaculture, including fish farms, nurseries, farms, and transportation logistics. During transportation, the low temperature and high purity of liquid oxygen can effectively ensure the survival rate and quality of aquatic products.
2. Green grain storage
- Low-temperature grain storage technology: Low-temperature grain storage is to control the temperature so that the grain is in a low-temperature state below 15°C or a quasi-low-temperature state below 20°C to improve the stability of the grain. Cryogenic liquid oxygen storage tanks can be used in conjunction with cryogenic grain storage technology to provide a low-temperature environment, reduce grain respiration and pest occurrence, and extend storage period.
- Reduce the use of pesticides: Traditional grain storage methods often rely on chemical pesticides to control pests, while cryogenic grain storage technology can reduce the use and residue of pesticides, and is a green, environmentally friendly and safe way to store grain. The application of liquid oxygen storage tanks further improves the controllability and safety of the grain storage environment.
3. Technical advantages
- Efficient oxygen supply: The oxygen supply efficiency of liquid oxygen storage tanks is much higher than that of traditional oxygenation methods. 1 cubic meter of liquid oxygen can replace 130 gas cylinders, greatly reducing transportation and storage costs.
- Safe and reliable: The liquid oxygen storage tank adopts a double-layer fixed vacuum powder insulation structure with good insulation performance, which can ensure the stability and safety of liquid oxygen.
- Convenient operation: The liquid oxygen storage tank is equipped with a pressure gauge and a differential pressure level gauge, which can monitor the storage volume and pressure changes in real time, making it easy to operate and maintain.
