Winemaking equipment heating mode

Electric heating and steam heating the advantages and disadvantages for most commercial winemaking equipment need saccharification step by step, so need to heat up in the process of saccharification, it's for heating mode and design requirement is higher. Electric heating: advantages: cheap, disadvantages: large equipment heating up slowly, and the local is too high, not suitable for thick mash saccharification relative to the electric heating steam for heating, steam temperature, the heating area is large, can guarantee the mash of even heating process is heated, the degradation of starch and protein in malt ideal; Won't appear the phenomenon of electric heating paste pot, paste pot will affect the taste of wine; And washing well washing pan. In 500, for example 1, electric heating power consumption is how much? 30千瓦( Normal is 6 groups of 5 kw heating tube) 2, steam heating boiler electricity power consumption is how much? 36 kw3, steam heating liquid gas boiler power consumption is how much? 0. 75千瓦( Pump) 4, steam heating with 3 - liquefied petroleum gas 4-4 kg/h, and natural gas 9-5 kg/h, gas 10 kg/h5, use good higher than the cost of the electric heating steam boiler? Normal wort preparation process, the heating time is 3. 5 - 4 hours, electric heating power 105 - 120 degrees, electric boiler electricity - 126 144 degrees, liquefied petroleum gas or natural gas boiler power is less than 3 degrees, 14 - to use natural gas 20Kg。 According to the commercial electricity 1 per kilowatt-hour. 1 yuan, 4 yuan/Kg to calculate gas peak price, electric heating electricity costs - 115 130 yuan, the average per litre of wine heating cost is 0. 23 - 0. 26 yuan; The electric boiler electricity cost is 138 - 158 yuan, the average per litre of wine heating cost is 0. 28 - 0. 32 yuan. Liquefied petroleum gas or natural gas boiler power less than 3. 5 yuan, the use of liquefied gas 56 - 60-80 yuan, total 83 yuan, the average per litre of wine heating cost is 0. 12 - 0. 17 yuan; Direct heating, electric heating tube devices do not increase evaporation 50 kg, 36 kw electric power, boiler softened water, cost 10000 yuan of above evaporation 50 kg liquefied gas boiler, with demineralized water, costs 15000 yuan
