Gravity filling is a process of filling containers by allowing gravity to push the liquid into the container.

• Liquid is poured into a container from a higher point, allowing gravity to fill the container.

• The height difference between the liquid source and the container determines the speed of filling.

• Commonly used in industries like food and beverage for filling bottles and containers.

• Gravity filling is a simple and cost-effective method of filling containers with liquid.

The capacity of the beer tanks varied depending on the specific tank, ranging from 1000 to 5000 liters.

• Capacity of beer tanks ranged from 1000 to 5000 liters

• Different tanks had different capacities

• Capacity was determined based on production needs

Preform yield is the percentage of usable preforms produced in a manufacturing process.

• Preform yield is calculated by dividing the number of usable preforms by the total number of preforms produced and multiplying by 100.

• It is an important metric in manufacturing to assess the efficiency of the production process.

• For example, if 900 usable preforms are produced out of 1000 total preforms, the preform yield would be 90%.

The process of preparing beer involves malting, mashing, boiling, fermenting, conditioning, and packaging.

• Malting: Barley grains are soaked, germinated, and dried to create malt.

• Mashing: Malt is mixed with hot water to extract sugars.

• Boiling: The sugary liquid (wort) is boiled with hops for flavor and bitterness.

• Fermenting: Yeast is added to the cooled wort to convert sugars into alcohol and carbon dioxide.

• Conditioning: The beer is aged to develop flavors and clarity.

• Packagin...read more
