Analysis of Heat Energy Constitution and Application Potential about Solar-assist-ed Heat Supply Noodle Drying Chamber in Chinese Dried Noodle Drying Process
For studying heat energy constitution, energy-saving effect and cost of installation and maintenance about solar energy assisted heat supply drying noodle drying process in chamber, a production line which energy was supplied by solar and coal was chosen as research object, coal consumption in different time periods, time of solar energy utilized and noodle produc-tion were monitored, 9 days survey was conducted during 4.28-4.29, 6.01-6.03, 7.28-7.29, 2015. Results showed that, in survey period, average time of coal heating alone was 16.5h, unit coal consumption was 28.60-32.05kg/t (noodle product); so-lar combined with coal heating 5.64h, unit coal consumption was 18.32-20.53kg/t, share 37.12%of total energy consumption in this period; solar heating alone (without coal) 1.88h; share17.51%about whole energy consumption in noodle production of all day, equivalent to saving coal 257.94kg, approximately equal to coal consumption about 8.05-9.02t noodle production. Suppose annual production of 200d, it was estimated that 43.48t of standard coal was saved annually, reducing carbon emissions 113.05t/year; assuming coal priced (243-251MJ/kg) at 600-800Yuan, could reduce production costs 30 953-41 271yuan/year.
