They recently purchased a new Mecmar\u00a0S 34\/255 T dryer with LPG-fired air vein burner<\/strong>. This allowed the company to purchase wheat and corn from producers during the harvesting season and to autonomously dry and stock it. The\u00a0procurement costs of the grain<\/strong>\u00a0immediately reduced considerably, and thanks to the use of the dryer with gas burner, gave them a product without impurities.<\/p>\n This makes\u00a0the feed produced healthier, gives it better quality and safer for animals while lowering production costs.<\/strong><\/p>\n LPG (Liquefied Petroleum Gas) is a mixture of hydrocarbons, mainly including propane and butane. When these two mixed gases are pressurised, they quickly pass to the liquid state, allowing LPG to be easily introduced into pressurised cylinders or tanks. It is therefore easy to transport. Just think that\u00a0LPG in the liquid state takes up 270 times less volume than in its gaseous state<\/strong>.<\/p>\n Like natural gas,\u00a0LPG combustion is eco friendly<\/strong>\u00a0as the amount of pollutants and of greenhouse gases released into the atmosphere during combustion is less than other fuels. To give one example, LPG combustion produces approximately 25% less CO2 than diesel oil combustion and approximately 50% less CO2 than carbon combustion. Since LPG especially comes from the production of natural gas,\u00a0it is also non-toxic and does not harm the soil<\/strong>, water and groundwater in case of leakage.<\/p>\n Considering the heat produced, we can affirm that\u00a0LPG has a higher calorific value<\/strong>\u00a0when compared to other fuels. To put it simply, we can state that the flame generated by LPG is hotter, which means greater efficiency for the burner. Without going into greater detail, a cubic meter of natural gas produces 9500kCal while LPG develops approximately 11500 kCal per kilogram. Keeping in mind that a litre of LPG weighs a bit less than a half kilo, we can affirm that\u00a00.75 kg of LPG supplies the same amount of energy as that produced by a cubic meter of natural gas.<\/strong><\/p>\n To make an economical assessment of an LPG system, in addition to the price of the fuel, we also have to take into account other\u00a0costs relative to the system<\/strong>\u00a0such as the cost to purchase and install the tank,\u00a0routine maintenance expenses<\/strong>\u00a0and\u00a0any financing<\/strong>\u00a0reserved for the installation and use of combustion systems more eco friendly than previous traditional systems which were more pollutant.<\/p>\n The dryers which incorporate the\u00a0air vein burner designed, developed and built at<\/strong>\u00a0Mecmar differ from most solutions on the market mainly due to the supply of this type of burner which comes directly from the LPG tank in the liquid state. This\u00a0first of all considerably simplifies the system<\/strong>\u00a0to be implemented respect to traditional systems where the gas-fired burner only operates with LPG in the gaseous state.<\/p>\n In a traditional system (Figure 2), the heating system consists of: tank, pressure relief valves, vaporisation, gas train, gas burner (mounted on the dryer). Components supplied by different suppliers, each of which must be referred to both in the installation stage and in the subsequent stages of use and maintenance of each component, adding up the expenses.<\/p>\n In the Mecmar system with LPG-fired air vein burner (Figure 3), the system is reduced to simply two elements: the tank, some safety devices and the air vein burner, with an extremely reduced layout both for installation and management\/maintenance of the system.<\/p>\n Briefly, here are some elements which distinguish the\u00a0air vein burner<\/strong>:<\/p>\n <\/p>\n Published data refer to corn and are calculated with mathematical models that use clean and ripe products and in normal operating conditions with 120\u00b0C drying air temperature and one hour cool-down time.
