1. Warm up
Generally speaking, when the pushed wort is immersed in the heating device, the flow rate of steam is very low at this time. Most of us know that the temperature of the wort will gradually decrease throughout the drawing process, and if we start heating after the drawing is fully completed, it will definitely take longer before steaming, preheating will definitely help maintain the temperature Levels are comfortable or gradually increased.
2. Primary boiling
This means the wort is just boiling, no more than 30 minutes at a time. At present, Sinotruk is not fully open, and the introduction of wort is still under development.
3. Boiling
The quality of cooking is mainly evaluated by boiling intensity. Typically, the boil intensity is between 8-12%.
