In the process of food processing, the gas exposed to the product needs to meet a series of requirements to ensure the safety and quality of the food. Here are some of the main gas requirements:
purity requirements: The gas should be of high purity to avoid the introduction of impurities or contaminants. Especially for gases used for packaging or preservation, such as nitrogen, carbon dioxide, etc., purity requirements are particularly important.
Sterility requirements: Gases used in food processing should be sterile to prevent microbial contamination. This is usually achieved by filtration and sterilization processes.
Non-toxic: The gas that comes into contact with food must be non-toxic to ensure that it will not cause chemical contamination to the food.
Chemical stability: gas in contact with food, should maintain chemical stability, no adverse reactions with food ingredients.
Suitable oxygen content: For some foods, it is necessary to control the oxygen content in the package to prevent oxidative deterioration of the food. For example, the use of nitrogen or carbon dioxide instead of oxygen in the packaging can extend the shelf life of food products.
Compliance with regulatory requirements: The gas used should meet the requirements of relevant regulations and standards, such as the FDA (US Food and Drug Administration) or the corresponding regulatory agencies in other countries/regions.
Humidity control: For some foods, it is also necessary to control the humidity inside the package to prevent the food from getting wet or drying out. This may require the use of a gas with a specific humidity.
No peculiar smell and non-corrosive: The gas should have no peculiar smell, so as not to affect the flavor of the food, and it should also be non-corrosive to protect the packaging materials of the food.
In summary, the gases exposed to food processing products need to meet the requirements of purity, sterility, non-toxicity, chemical stability, appropriate oxygen content, compliance with regulations, humidity control, and no odor and non-corrosive. These requirements help ensure the safety and quality of food, extend the shelf life of food, and meet consumer needs and expectations.
When discussing the question of which is better, water-cooled screw air compressor or water-cooled scroll air compressor, we seem to have entered a competition in the mechanical world. The two contestants each show their strengths, making it difficult to choose. First of all, let us look at the water-cooled screw air compressor.
Whether the air compressor can run for a long time is a complex problem, because it depends on many factors, such as the type of air compressor, quality, use environment and maintenance. Generally speaking, the air compressor is not recommended to run continuously for a long time for the following reasons
The pressure range of the plant gas source varies depending on the gas type and application requirements. In general, gas sources commonly used in factories include compressed air, inert gases (such as nitrogen, argon, etc.) and industrial gases (such as oxygen, acetylene, etc.)
As the core power equipment in industrial and civil fields, air compressor (referred to as air compressor) stores energy through compressed air to provide power for various tools and systems. It has a wide range of applications, covering multiple scenarios from basic production to high-end manufacturing. The following is the specific application points
The maintenance time of air compressor equipment can be determined according to different maintenance levels and usage conditions. Generally speaking, the maintenance cycle of the air compressor can be divided into the following stages: the first regular maintenance: usually after 500 hours of operation of the air compressor. This time
When the air in the air compressor contains moisture, the following methods can be adopted to deal with it: 1. install a drain valve and install a drain valve at the bottom of the air compressor cooler: the bottom of the air compressor cooler is usually provided with a drain valve, which can be opened regularly,
The principle of permanent magnet variable frequency air compressor is to replace the excitation winding with permanent magnet for excitation. When the three-phase stator windings of the permanent magnet motor (each with a difference of 120 ° electrical angle) are connected to the three-phase alternating current with a frequency of f, a rotation at a synchronous speed will be generated
The compressed air in contact with traditional Chinese medicine shall meet the core standards of oil-free, dry, clean and sterile. The specific requirements are as follows: 1. oil-free requirements Oil control: compressed air shall not contain impurities such as lubricating oil to avoid polluting traditional Chinese medicine. Generally, the oil content is extremely low, such as less than 0
There are significant differences between air compressor oil and ordinary oil in terms of use, composition, viscosity grade, operating temperature range, performance requirements and cleanliness, which determine that the two are not interchangeable. The following is a specific analysis: use: air compressor oil: mainly used
Yes, the air compressor needs to discharge water every day. Under normal operation, the air compressor needs to discharge water once a day to remove the accumulated moisture inside the equipment. If the ambient humidity is high or the water content in the air is high, the frequency of water discharge needs to be increased to avoid moisture damage to the equipment
