Laundry Detergent Filling Machine Selection Guide

Laundry detergent has a variety of packaging specifications, from 50ml trial packs, 500ml household packs, 2L, 5L large-capacity

household packs, to industrial barrels of more than 20L, covering household, commercial, industrial and other scenarios. Different

packaging specifications have different requirements on the filling range and speed of the filling machine. At the same time, some

products need to be adapted to special-shaped bottles, which requires the filling machine to have good flexibility and adjustability,

and can quickly switch different filling specifications to meet the needs of multi-category production.

Laundry detergent is a fast-moving consumer good, and consumers have high requirements on the consistency of product net

content. Industry standards have clear regulations on the filling error of laundry detergent. High-quality production enterprises

need to control the filling error within ±0.5% to ensure stable product quality and enhance consumer trust. At the same time, the

raw material cost of laundry detergent is relatively high. Reducing dripping, splashing and residue during the filling process and

reducing the loss rate to below 0.5% is the key for enterprises to control costs and improve profits.

The core principle of choosing a laundry detergent filling machine is "adapting to the characteristics of laundry detergent, matching production needs, and balancing efficiency and cost". Combined with industry practice experience, it is necessary to comprehensively consider from the following 5 core dimensions to avoid selection mistakes and achieve perfect adaptation between equipment

and production.

The filling method is the core of selection, which must fully match the viscosity and foaming characteristics of laundry detergent to

avoid inaccurate measurement, liquid leakage and other problems:

- Low-viscosity laundry detergent (such as ordinary dilute type): good fluidity, not easy to hang on the wall, can choose gravity

filling machine or flow meter filling machine, with fast filling speed, simple structure and low maintenance cost. At the same time, it

is necessary to equip with anti-dripping device to avoid dripping and polluting the bottle body after filling.

- Medium and high viscosity laundry detergent (such as super-concentrated thick type, laundry detergent with softening

ingredients): poor fluidity, easy to hang on the wall and foam, priority to choose piston filling machine or submersible filling

machine. Among them, the submersible filling machine can extend the filling head into the bottom of the bottle for filling, and

gradually lift it with the rise of the liquid level, effectively preventing foaming; the piston filling machine has high measurement

accuracy, which can effectively solve the problems of wall hanging and inaccurate measurement of high-viscosity materials,and

the filling error can be controlled within ±0.2%.

- Foam-prone laundry detergent (such as mild laundry detergent containing rich surfactants): in addition to choosing the

submersible filling method, you can also choose a filling machine with foam suppression function, or equip with a vacuum

defoaming device to reduce the impact of foam on filling accuracy and reduce loss.

The efficiency, number of filling heads and filling range of the filling machine need to be accurately matched with the enterprise's

production scale and packaging specifications, so as to avoid "big machine for small use" or "small machine for big use", resulting

in cost waste or insufficient production capacity:

- Small enterprises/start-ups (daily output ≤5000 bottles): mainly engaged in small-batch and multi-specification production,

can choose semi-automatic filling machines (such as pure pneumatic piston filling machines), which are simple in structure,

convenient in operation and low in cost. The filling speed can reach 0~50 bottles per minute, adapting to the filling range of

50ml~5L, meeting the needs of small-batch production, and facilitating flexible adjustment of filling specifications.

- Medium-sized enterprises (daily output 5000~50000 bottles):need to balance efficiency and flexibility, priority to choose

automatic linear filling machines (such as 12-head models), filling speed up to 3600 bottles per hour (500ml specification),

supporting 50ml~20L full-specification filling, equipped with PLC touch screen, which can store 50 groups of formulas, one-key changeover only takes 90 seconds, adapting to multi-category and multi-specification production, effectively improving production efficiency.

- Large enterprises (daily output ＞50000 bottles): mainly engaged in large-scale and standardized production, choose automatic

multi-head filling machines (16 heads and above) or filling production lines, which support 24-hour continuous operation, can be

seamlessly connected with capping, labeling and palletizing equipment to realize the closed loop of full automatic production. The

daily output can exceed 50000 bottles, and it is equipped with constant pressure feeding design to reduce energy consumption by

15% and strictly control production loss.
