The brewer's grains dryer dehydrates and dries the distiller's grains through high temperature and hot smoke, so the choice of heat source is very important for the operation of the equipment and the quality of finished products, not only can ensure the drying effect of materials, but also energy saving and environmental protection, saving production costs for enterprises.
With the continuous advancement of national environmental protection policies, how to solve the problem of clean energy of brewer' grain dryer has become an urgent task for investors in the processing and reuse of brewer's grain feed. Specifically, there are various types of combustion coal, oil, gas, electricity, biomass and so on, so how can we choose the most suitable heat source for the beer grains dryer?
1.To meet the drying requirements of finished distillers' grains, the heating temperature and the cleanliness of heat source have a great influence on the feed quality of distillers' grains.
2.To meet the requirements of environmental protection, some burning heat sources will produce odor or smoke in the combustion process, and pollution will be generated when discharged into the atmosphere. Such heat sources should be used with caution.
3.Economical and easy to obtain, the chosen heat source should be suitable for the location, consider both the cost of various heat sources and the ease of access.
4.Safe and reliable, this point is more important to the direct combustion heat source, some dry materials are flammable, explosive or easy to oxidize, the best treatment of this kind of material with indirect heat transfer heat source, choose direct combustion to have special flame retardant or explosion protection measures.
5.Easy to operate, in order to ensure stable quality of distillers, the selected heat source shoule be as convenient as possible for operation and automatic control.
