Design and Manufacture of Cold Plasma Generator to Preserve Milk and Beef Samples from Components Simple and Low-Cost College
The cold plasma device was manufactured locally in the city of Hit, and laboratory tests were conducted on this device in the laboratories of Hit General Hospital as well as in the laboratories of the Department of Environment and Water Resources / Ministry of Science and Technology / Baghdad This device was made locally from available raw materials and cheap price, in addition to its consumption of electrical energy by a small percentage that may not exceed (1 amper), and is characterized by ease of use and transportation, and it does not need a long time when completing its work, and according to the nature of the foodstuffs used For examination, the temperature of the plasma generated by the device does not exceed (25) degrees Celsius. Cold plasma testing was performed on milk and meat samples, microbiological experiment was conducted and chemical composition analysis was performed. The microbiological experiment showed a reduction in the microbial load in the milk and meat sample, and the results of the chemical composition analysis showed minor changes in it.
