Production lines for carbonated soft drinks · Carbonation targets in volumes of CO2, chilling and forced carbonation, syrup mixing, isobaric (counter-pressure) filling, PET, glass and can formats, line output in bottles per hour
A carbonated soft drink production line turns treated water, sugar or sweetener and flavour concentrate into a carbonated drink in PET bottles, glass bottles or cans: syrup is prepared and blended with water, the beverage is chilled and carbonated with CO2 to a set number of volumes, filled under counter-pressure so the gas stays in solution, capped or seamed, warmed if needed, coded, labelled and packed. Ask three things first: what carbonation level and products the line must hold, which package formats and sizes it fills, and what output in bottles or cans per hour it must reach.
Complete production lines for carbonated soft drinks — colas, flavoured sodas, mixers and sparkling waters — from water treatment, syrup preparation, mixing and carbonation to isobaric filling, closing, warming and packing. Individual machines covered on their own pages, such as rotary bottle fillers, cappers, blending systems (see automated beverage batch blending system) and carbonation controls (see automated beverage carbonation control system), are outside this page except where compared.

A University of Florida IFAS extension guide states that dissolved CO2 is given in grams per litre or in volumes of CO2 per volume of liquid, with 1 vol/vol equal to about 1.96 g/L; about 0.6 volumes is the minimum people detect and 8 volumes the recommended absolute maximum, beyond which bite and bottle pressure become problems; its table gives 3.5–4 volumes for high-carbonated sodas such as colas and 2.5–3.5 for lemon-lime sodas, club soda and tonic water. [1]
The guide explains that carbonation level depends mainly on CO2 pressure and temperature because water dissolves more CO2 at lower temperature for a given pressure, that forced carbonation — CO2 driven into the liquid in a pressurised vessel — is the method the sparkling-beverage industry relies on, and that the carbonated product must be bottled under pressure or the CO2 escapes; in its small-scale example, 5 vol/vol at 5 °C needs about 38 psi gauge. [1]
SinoPAK describes its CSD lines as chilling water before carbonation for stable CO2 absorption, high-precision beverage mixing with CO2 blending and two-stage cooling before the filler, and syrup and beverage mixing configured to the cola, soda or flavoured formula. [2]
Editorial calculation: 3.5 volumes × 1.96 g/L ≈ 6.9 g of CO2 per litre, about 2.3 g in a 330 ml can; set the target in the unit your quality laboratory measures. [1]
Give the supplier the product list with carbonation targets (volumes or g/L), Brix and syrup ratios, fill temperatures, package formats and sizes (PET, glass, cans), output per format in bottles or cans per hour, water source and treatment needs, sugar and concentrate supply, closures, labels and secondary packaging, CO2 supply, available space and utilities, and the documents and acceptance tests required.

MIC Machinery explains that soda filling, unlike still filling, needs counter-pressure technology to prevent foaming and keep carbonation, and that its machines combine rinsing, isobaric filling and capping in one monoblock; its listed models run from 200–800 bottles per hour on a semi-automatic glass-bottle filler and 800–1,500 BPH on an 18-18-1 glass-bottle machine to 2,000–3,000 BPH on an 18-18-6 PET filler, 3,000–5,000 BPH on a 24-24-6 and 5,000–12,000 BPH on a 12-12-1 glass-bottle plant. [3]
SinoPAK sets the project scope as water treatment, mixing, carbonation, filling, warming and packaging with low-temperature isobaric filling, and treats PET, glass and can CSD lines as different configurations because carbonated drinks behave differently in each package; its PET line uses an isobaric 3-in-1 filler followed by warming, coding and labelling. [2]
TECH-LONG lists the questions a CSD filler must answer — filling temperature against energy use, foaming, fill-level accuracy, residue at the neck finish and CO2 content — and cites filling without purging for high CO2 utilisation and speeds up to 60,000 BPH for 500 ml bottles. [4]
Editorial calculation: 60,000 bottles/h × 0.5 L = 30,000 L/h of finished beverage, which the syrup room, carbonator and chilling must supply continuously. [4]
