Apple cider vinegar is a fermented beverage rich in nutrition and flavor. Its production process requires strict temperature control management and a large amount of heat energy support, involving cleaning, fermentation, concentration, sterilization, drying and other links. Traditional heating methods consume a lot of energy and are difficult to control accurately, while the application of high-temperature heat pumps can provide efficient, environmentally friendly and stable heat energy solutions for apple cider vinegar production.
Heat demand in apple cider vinegar production
The apple cider vinegar production process is divided into multiple links, and the temperature requirements of each stage are as follows:

- Temperature requirement: 40~50°C.
- Heat source requirement: low-temperature hot water.
- Fermentation
- Process: Apple juice is fermented by yeast and acetic acid bacteria to form alcohol and acetic acid, and the fermentation temperature needs to be kept constant.
- Temperature requirement: 2530°C (alcohol fermentation); 3035°C (vinegar fermentation).
- Heat source requirement: low-temperature heating and temperature control.
- Concentration and evaporation
- Process: Vacuum evaporation and concentration of apple cider vinegar to increase flavor concentration.
- Temperature requirement: 50~80°C (vacuum evaporation).
- Heat source requirement: medium-temperature hot water or hot steam.
- Sterilization
- Process: Pasteurize the finished apple cider vinegar to ensure product safety and shelf life.
- Temperature requirement: 80~95°C.
- Heat source requirement: high-temperature hot water or steam.
- Drying and packaging
- Process: Part of the concentrated apple cider vinegar needs to be dried to make it into powder or other forms.
- Temperature requirement: 60~100°C.
- Heat source requirement: hot air system.
- Cleaning and disinfection
- Process: Clean production equipment and workshop facilities to ensure sanitary conditions.
- Temperature requirement: 70~90°C.
- Heat source requirement: hot water or steam.
