A lot should be considered when you plan to open your brewery like brew tech,brewery equipment configuration,brewery equipments cost and price,find a location for brewery, license and regulation of brewery. This article column is specially to answer some common question during brewing.
How to reduce the heat consumption in the wheat making workshop?
The heat energy consumption of the wheat making workshop is mainly concentrated in the drying furnace. At present, the heat energy utilization rate of the good drying furnace is 75% ~ 80%, and the poor is about 50%. The main reasons for the low utilization rate of heat energy are: unreasonable design of drying furnace, poor sealing of air duct, mixing chamber or heat exchanger, and poor utilization of waste heat. In order to reduce the heat energy consumption of wheat making workshop, the following aspects should be improved.
① Single layer high-efficiency drying furnace is used to improve the dehydration effect. For ordinary single-layer drying furnace, double-layer drying furnace and three-layer drying furnace, the intensity of removing wet air should be increased, and the axial flow fan with large flow rate should be replaced.
② Improve the sealing degree of hot air channel in drying chamber, mixing chamber, heater, etc., strengthen the sealing of furnace door, air inlet and outlet facilities, and prevent the leakage of cold air during the whole return air in the baking stage from affecting the heating effect.
3. For two (or more) single-layer drying furnaces in parallel, the high-temperature air can be sent to the other furnace as hot air for dehydration, so as to reduce the heat energy consumption of the other furnace during dehydration period.
④ The hot air discharged above 60 ℃ is used to preheat the fresh cold air before entering the air heater to reduce the heat energy consumption of the heating air.
⑤ Using the waste heat of the heating source to preheat the fresh cold air and then enter the air heater to reduce the heat consumption of the heating air, or using the high-efficiency compound heat exchanger to make use of the waste heat, only a small amount of heat source can achieve the purpose of heating the air and reducing the heat consumption.
