How to test the vacuum of vacuum packaging of meat products?

At present, most of the meat products commonly on the market are vacuum-packed, and the air in the package is removed by vacuuming to prevent the meat products from coming into contact with the air for a long time, causing microbial growth, reproduction and oxidative deterioration of meat products, and extending the shelf. Therefore, the control of the degree of vacuum in the vacuum package (ie the volume of residual gas in the package) is critical. In the daily quality monitoring process, the vacuum packaging residual oxygen meter can be used to test the volume of residual gas in the package.

There is no domestic testing standard for oxygen residuals in vacuum packaging. Labthink RGT-01 Vacuum Packaging Residual Oxygen Meter is a testing instrument for gas residuals in vacuum packaging. It is also rare in the market. Testing equipment. The device adopts the principle of combining differential pressure method and liquid level analysis technology, and can be used for the sealing of vacuum packaging in the fields of food, medicine, cosmetics and the quantitative detection of the volume of trace gases in the package. The test range is 0 ~ 15ml (air volume), and the vacuum range is 0 ~ -90KPa.

RGT-01 vacuum packaging residual oxygen meter is easy to operate. When testing, put the chicken vacuum package into the vacuum chamber, fill the vacuum chamber with water, cover the sealing plate, and then slowly inject water into the metering cylinder to the specified Area, cover the upper cover, set the pressure parameters, open the vacuum pump and start vacuuming the vacuum chamber. The sample in the vacuum chamber expands under the action of the internal and external pressure difference. When the set pressure is reached, the test stops automatically. The software of the instrument configuration The volume of oxygen remaining in the package is automatically calculated based on the data measured by the test. The user only needs to read the final test result.
