Carbonated beverages like soda water, beer, and sparkling water are beloved across the world. But producing these bubbly csd drinks on an industrial scale comes with immense energy demands. Filling machines must rapidly cool drinks before filling without sacrificing carbonation. At the same time, maintaining low temperatures in filling rooms and production areas consumes massive electricity.

Fortunately, the advanced technology is transforming carbonated beverage water filling equipment to slash energy consumption and costs. Keep reading to learn how it works and the benefits for beverage producers.

Overview of Carbonated Soft Drink Production Challenges

China’s annual energy consumption for beverage production exceeds 1475.74 million tons of standard coal, accounting for about 20% of the food industry’s total energy use.

The traditional beverage production beverage filling process requires huge amounts of steam to heat water for production units. Additionally, many process units need cooling, provided by energy-guzzling refrigeration machines. This results in high fossil fuel and electricity consumption but low overall energy efficiency.

Therefore, efficiently utilizing heat and cold energy within beverage production is a pressing technical challenge. Absorption technology provides a solution.

How Absorption Carbonated Filling Machines Work

Absorption filling machines incorporate an absorption heat pump with key components:

  • Generator: Driven by a heat source.
  • Condensers: Release heat to a medium like water.
  • Evaporators: Absorb heat from a medium.
  • Absorbers: Absorb vapor from evaporators.

The absorption cycle moves heat from where it’s not wanted to where it’s needed.

The Absorption Cooling Process

Beverages must be chilled before filling to maximize carbonation retention.

Chilled water circulates between an evaporator and the filling machinery. The evaporator absorbs heat from the water, cooling it. The chilled water then cools beverages in the CSD filling machine.

The Absorption Heating Process

Filled bottles must be warmed to room temperature.

Heated water circulates between absorbers/condensers and a heating unit. The absorbers and condensers release heat into the water, warming it. The hot water then heats up bottles in the heating unit.

This reuses heat that would otherwise be wasted, boosting efficiency.

Case Study: Absorption Drinks Filling Machine for Carbonated Beverages

Let’s walk through a complete absorption system for carbonated beverage filling.

It contains:

  • Heating unit
  • Filling machine
  • Absorption heat pump

Step 1: Cooling and Filling

The filling machine connects to an evaporator, forming a chilled water loop.

The evaporator absorbs heat from the water, cooling it. The water flows into the filling machine, cooling beverages before filling.

After filling, carbon dioxide gas flows from a condenser into the filling machine to carbonate the beverages.

The condenser heats liquid CO2, converting it to gas for carbonating.

Step 2: Heating Filled Bottles

The heating unit, absorbers, and condensers form a hot water loop.

The absorbers and condensers release heat into the water, warming it. The hot water flows into the heating unit to heat up filled bottles.

Additional Energy Savings

A bottle cooling unit can connect to another evaporator, creating a second chilled water loop. This chills empty bottles before filling, capturing waste heat.

Compared to traditional filling machines, absorption technology provides:

Energy Savings

  • Reuses heat instead of wasting it.
  • Reduces fossil fuel and electricity consumption.
  • Cuts energy costs.

Environmental Benefits

  • Lowers carbon emissions.
  • Reduces pollution from energy production.

Precision Filling

  • Maintains optimal temperatures for filling.
  • Ensures high carbonation retention.


  • Customizable for different production needs.
  • Works for various bottle shapes and sizes.


  • Durable, long-lasting advanced filling equipment.
  • Easy to operate and maintain.


  • Prevents overheating and damage to drinks.
  • No risk of burns from hot equipment.

Applications Beyond Carbonated Beverages

While absorption filling shines for carbonated drinks, it works for other beverages too.

The technology can heating and cool non-carbonated liquids like juices, teas, coffees, and more. It’s ideal for producing shelf-stable aseptic beverages.

Absorption Filling and Capping Line for Non-Carbonated Beverages

Here’s one example configuration for an aseptic beverage bottling line:

Step 1: Initial Heating Unit – Preheats syrup.

Step 2: Sterilization Heater – Uses steam to sterilize syrup.

Step 3: Initial Cooling Unit – Precools sterilized syrup.

Step 4: Final Cooling Unit – Cools syrup to bottle filling temperature.

Absorption Heat Pump

Hot and chilled water loops transfer heat between units.

This precisely controls temperatures during heating, sterilization, and cooling. It allows aseptic speed filling with minimal product damage or nutrient loss.

Choosing the Best Absorption Filling Machine

If you’re sold on absorption filling, how do you pick the right system? Here are key factors to consider:

  • Output: Match capacity to your production volumes.
  • Beverage Types: Optimize for your specific products.
  • Speed: Faster filling reduces costs but requires more power.
  • Flexibility: Customizable machines suit changing needs.
  • Budget: Balance value, energy savings, and quality.
  • Certifications: Look for ISO and CE markings.
  • Aftersales Service: Pick a provider with full service and support.

It’s wise to consult filling machine manufacturers early when planning a new bottling facility or upgrade. Experienced companies can suggest the optimal configuration and flow layout to maximize your investment.


Here are answers to some frequently asked questions about absorption filling technology:
