Pineapple beer is a fruit-flavored beer. Its production combines the process of juice processing and beer fermentation, and involves multiple thermal energy links that require precise temperature control, such as juice concentration, sterilization, enzymatic hydrolysis, and cleaning. Traditional heat source equipment such as gas boilers and electric heaters have high energy consumption and limited temperature control accuracy. High-temperature heat pump technology has brought significant energy saving and quality improvement to pineapple beer production with its advantages of high efficiency, environmental protection and precise temperature control.
