Introduction: DT-6D Atmosphere fresh-keeping packaging machine for laboratory is a box-type atmosphere fresh-keeping packaging machine introduced by our company to research institutes and universities and other food research institutes. The disposition, operation, driving form and required Space, etc. are in line with the requirements and characteristics of the laboratory. Microcomputer programmable controller and human-machine interface touch screen control system, the parameters set convenient, intuitive, accurate, stable and reliable operation of the program. According to the experimental preset data requirements of the project only once set the packaging parameters, you can continue to complete the desired packaging operations. The equipment adopts German high-precision gas mixing system, which can precisely change the types and mixing ratios of different fresh gases according to the preservation requirements of different foods. The adjustment precision is high and the gas mixing precision is better than ± 1%, which ensures the accurate experimental data Wrong. The German high-oxygen vacuum pump, achieved high vacuum, long service life, without routine maintenance, high safety factor. In oxygen concentrations greater than 21% of the environment, the high oxygen vacuum pump can effectively prevent the accidental deflagration caused by high oxygen content. The use of fully closed vacuum replacement, the application of vacuum pump closed vacuum chamber, the vacuum chamber to form a high degree of vacuum, and then filled with food suitable for the extension of the preservation of gas, gas replacement rate ≥ 99%. According to different types of food required for the preservation of gas, were selected three kinds of fresh gas, two kinds of fresh gas and a mixture of fresh gas mixture ratio to meet the needs of different experiments. Equipped with premixed gas conversion system. In a combination of oxygen, carbon dioxide, and other gases other than nitrogen, such as carbon monoxide, the premixed gas interface can be used and different gas conversions Equipment operation is simple and convenient, the operating parameters set is completed, just gently push the sealing mold can automatically complete the vacuum, inflatable, sealing, trimming, waste film recycling procedures. The whole set of equipment adopts the split design, that is, the packing equipment is mixed with the gas. The vacuum system can be placed separately according to the laboratory conditions and the space, and the two are connected by pipeline to meet the different conditions of the laboratory.
