About the solution

Dairy products demand the strictest sanitation: the filling zone runs inside an enclosed laminar-flow booth supplied with sterile air, and the equipment supports automatic CIP washing and SIP steam sterilization before every shift.

Container format determines the line's makeup. For bottles — a monoblock with peroxide disinfection; for cups — a filler with foil sealing and lid application; for pouches — a vertical form-fill-seal machine with longitudinal and cross seams.

Built into the design

Laminar-flow booth

The filling zone is isolated; air is supplied through HEPA filters under positive pressure.

Automatic washing

Closed-loop CIP with caustic, acid and sanitizer, with a program for each product.

Three container formats

Bottle, cup and pouch share common product preparation — the range can grow gradually.

Batch traceability

Wash, temperature and volume parameters are logged for every batch for quality control.

Line composition along the product flow

8 positions along the product flow. Every unit opens in the catalog: series, specifications, scope of supply and a quote request.

Line model selection

Selecting an ESL milk filling line

Output is given for a 1 L bottle; shelf life depends on the cleanliness of the filling zone and raw milk quality.

Model	Filling valves	Container	Output	Shelf life
EDS-D-ESL-8	8	PET/HDPE 0.2–1 L	3,000–5,000 btl/h	up to 30 days
EDS-D-ESL-12	12	PET/HDPE 0.2–2 L	6,000–9,000 btl/h	up to 45 days
EDS-D-ESL-18	18	PET/HDPE 0.2–2 L	12,000–18,000 btl/h	up to 45 days

The shelf life is achieved through a laminar flow of sterile air in the filling zone and container disinfection before filling; the condition is a maintained 2–6 °C cold chain.

Cup filling machine

Model	Lanes	Cup volume	Output	Closure type
EDS-CUP-4	4	100–200 mL	4,000–6,000 pcs/h	foil seal + lid
EDS-CUP-6	6	100–450 mL	8,000–12,000 pcs/h	foil seal + lid
EDS-CUP-8	8	100–450 mL	12,000–16,000 pcs/h	foil seal + lid

For a two-chamber cup (yogurt with topping), output drops by 15–20% due to the extra dose.

Pouch line for milk and plant-based drinks

Parameter	Value
Pouch volume	200 mL – 1 L
Output	3,000–6,000 pouches/h
Film material	multilayer PE/PA laminate
Seam type	longitudinal + transverse heat-seal

The pouch is a cost-effective alternative to a bottle in terms of packaging cost per liter of product, used for domestic markets and HoReCa.

Line process flow

The dairy line is built around a temperature chain from the storage tank to the finished-product pallet: the product must not warm above 6 °C at any stage. The head and tail composition depends on the container type — an ESL bottle, a yogurt cup, or an economical pouch.

Key line features

Laminar flow of sterile air in the filling zone reduces microbial load without full aseptic processing

Key line stations

What sits behind the nameplate output: contact-part execution, operating logic and service points for every station.

Blending and UHT block

Product preparation

High-shear blending unit: sugar, concentrate and stabilizer disperse without clumping.
Tubular or plate heat exchanger, holding and cooling on a set curve.
Homogenizer up to 200 bar — a stable emulsion with no separation in the bottle.
Jacketed buffer tank maintains the filling-supply temperature.

This station's equipment in the catalog

Core machines of the line

Equipment of the “Dairy Filling Line” layout: each tile opens the catalog with series, specifications and a quote request for that machine.

Intermediate product storage tank

A jacketed, agitated tank maintains 2–6 °C before filling, buffering the throughput difference between pasteurization and the line.

ESL filling line for PET/HDPE

Filling in a laminar flow of sterile air with UV or peroxide disinfection of the container and cap — shelf life up to 45 days under refrigerated chain.

Cup filling machine

Thermoforming or preformed cup infeed, dosing by weight or volume, foil sealing, and lid application on a single unit.

Doser for yogurt with fruit filling

Mass or piston doser with a wide-bore passage for fruit pieces, with layered filling for two-chamber cups.

Pouch filling line (doypack/pillow pack)

Pouch forming from film on a roll, aseptic filling, and hermetic seam sealing — an economical package for milk and plant-based drinks.

CIP station for the process loop

Circulation cleaning with alkali, acid, and sanitizer without disassembling the piping — between product changeovers and per the shift schedule.

Capping machine

Screw-cap application on the bottle or heat-sealing of a lid onto the cup with hermeticity checked on every unit.

Labeling machine

Shrink-sleeve or self-adhesive film label on the bottle and group marking on multipacks of cups.

Date coder and batch marking

Printing of fill date, shelf life, and batch number on the bottle, cup, and case with readability checking.

Shrink film / case packing and palletizing

Group packing of cup multipacks in shrink film, loading bottles into cases, and layer-by-layer pallet formation with stretch-wrap.

Which closure do you use

The cap type defines the capping block: heads, feeding and orientation of the closure, torque or press-on force. State your option in the request and we will select the head and sorter for it.

PCO 1881 / 28 mm / 38 mm

Plastic screw cap

The tamper-evident band tears on opening. Torque is set on the HMI and monitored on every chuck.

Capping unit: Magnetic screwing head

Ø 75, Ø 95

Foil seal + protective lid for cups

The foil is heat-sealed around the rim with temperature and dwell-time control, then a plastic lid snaps on top.

Capping unit: Heat-sealing station

foil 0.2–0.9 mm

Induction liner under the cap

The liner is welded to the finish after capping — tamper protection and seal integrity during transport.

Capping unit: In-line induction sealer

FAQ

What is the difference between ESL and aseptic?

ESL gives a shelf life of 21–45 days under cold chain and costs considerably less. Aseptic allows room-temperature storage for up to 6 months, but requires a sterile zone, trained personnel and a stricter regime.

Can several formats be filled on one line?

Product preparation is shared, while filling sections differ. This is a standard scheme for a dairy plant with a broad product range.

How much does the Dairy Filling Line cost?

Price on request: the budget depends on output, container type, line composition and the level of automation. After a short brief we send a preliminary estimate within 1–2 working days and a full quotation broken down by machine within 3–5 days.

What are the delivery and commissioning lead times?

Standard machines ship 8–12 weeks after the specification is confirmed, complete lines 12–20 weeks. Transport takes 2–6 weeks depending on the route; installation and commissioning on site take 2–4 weeks, with operator training included.

What output does this line reach?

The working range is 2,000–18,000 units/h. Exact output is confirmed against your container, product and shift plan: we calculate the line balance and keep a margin on the bottleneck machine.
