Under this background, the conference focused on the theme of “innovation-driven, leading the futureâ€, gathering upstream and downstream service companies in the whole industry chain of fruit and vegetable processing, packaging, cold chain, and quality management, aiming to build industry-wide exchange of scientific and technological achievements and sharing of innovative experiences. The excellent platform promotes the healthy development of the fruit and vegetable processing industry in China. To enlarge and strengthen the fruit and vegetable processing industry, provide the people with safe and abundant food supplies, and protect people's health.
China's fruit and vegetable industry has become the second largest agricultural industry after food crops. The abundant fruit and vegetable resources provide sufficient raw materials for the development of the fruit and vegetable processing industry. Therefore, as an emerging industry, the fruit and vegetable processing industry has become increasingly prominent in the development of China's agriculture and rural economy. It has become the most important source of economic resources and new economic growth points for rural areas and farmers in China, and it has become an export-oriented development potential. The regional characteristics, high-efficiency agricultural industry and pillar industries in China's agriculture.
During the twelfth five-year period, biotechnology, membrane separation technology, high-temperature instantaneous sterilization technology, vacuum concentration technology, micro-encapsulation technology, microwave technology, vacuum freeze-drying technology, sterile storage and packaging technology, ultra-high pressure technology, ultra-fine grinding technology, ultra Critical fluid extraction technology, extrusion and extrusion technology, genetic engineering technology and related equipment have been widely used in the processing of fruits and vegetables. Advanced aseptic cold canning technology and equipment, cold beating technology and equipment have been rapidly applied in the deep processing of fruits and vegetables in Europe and the United States and have been continuously improved.
During the “Thirteenth Five-Year Plan†period, the production of fruits and vegetables will continue to maintain the momentum of rapid development. In the next 5 to 10 years, the fruit and vegetable processing industry of our country will strive to improve the quality of fruits and vegetables and adjust the structure of varieties on the basis of ensuring the supply of fruits and vegetables. The storage and transportation of large fruits and vegetables after processing make the fruit and vegetable industry in China change from quantity-benefit to quality-benefit. Accelerate the integration of production, sales and sales of fruits and vegetables, form specialization of fruit and vegetable production, scale of processing, service socialization, and integration of science, industry, and trade, and transform and upgrade the technological level of fruit and vegetable processing industries with high-tech such as information and biology.
Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
