For investors seeking to enter the field of mass production while maintaining the characteristics of craft beer, the 3000L craft beer brewery is an excellent choice. It boasts the requisite production scale to accommodate large orders and long-term contracts while retaining the personalization and small-batch customization capabilities of craft beer.
Process characteristics
Ingredients handling (optional) method: dry milling
Heating method: electric / steam / direct fire
Heating with steam: the temperature can be precisely regulated within the range of 45-76°C at a rate of 1-1.2°C/min and within the range of 52-100°C at a rate of 1.2-1.5°C/min.
Mashing: infusion mashing / decoction processes
Lautering: Chollima system
Boiling: Standard atmospheric boiling / low-pressure boiling / internal calandria with the heatwave
Removal of the coarse break: whirlpool tank
Wort Cooling: one stage cooling
Fermentation process: closed pressure fermentation
Fermenter cooling method: ethylene glycol or alcohol via dimple jackets
The cooling speed is 0.8-1°C/hour for 5°C-18°C and 0.05-0.2°C/hour for 0°C-5°C. The cooling parameters can be set to achieve precise control of cooling speed at different stages.
The whole cooling system utilizes a 33% hybrid refrigerant, which is a -5°C ethylene glycol. This refrigerant provides efficient cooling, while also maintaining a low operating temperature.
Glycol water supply temperature: -3℃~-5℃ Glycol water supply pressure: 3-4 bar
Hot water supply temperature: 82-85℃, Hot water supply pressure: 3-4 bar
Cold water supply temperature: 1-3℃, Cold water supply pressure: 3-4 bar
