Product Overview
The ZLGF series rinsing-filling-capping monoblock is a rotary filling system independently developed for the beverage industry, combining three core processes: bottle rinsing, liquid filling and cap sealing. The integrated design eliminates intermediate conveying links, greatly reduces the risk of secondary pollution, and significantly saves floor space compared with split-type equipment.
All parts in contact with products are made of food-grade 304 stainless steel with mirror-polished surface, free of sanitary dead corners and fully compliant with food safety standards. The machine is equipped with an industrial PLC control system and touch screen HMI, supporting parameter setting, real-time status monitoring, production counting and fault alarm functions. The rotary continuous working structure ensures smooth high-speed operation and supports 24/7 uninterrupted production.
This series covers 9 standard models with capacity from 3,000 to 35,000 bottles per hour, compatible with PET bottles of 200–2000ml in volume. Format changeover can be completed simply by adjusting star wheels and guide rails, with short downtime and high flexibility. It can be matched with bottle unscramblers, sterilizers, labeling machines and shrink wrappers to form a complete automatic beverage production line, widely applicable to drinking water, fruit juice, tea beverage and plant protein drink production.
Equipment Principle
The machine adopts rotary continuous working principle, driven by gear transmission and cam indexing mechanism to realize precise synchronous operation of all stations. The whole process is fully automated as follows:
- Rinsing Station Empty bottles are fed into the rinsing turret via the infeed star wheel. Bottle clamping grippers hold the bottle neck and rotate it 180° with the mouth downward. High-pressure clean water sprays the inner wall thoroughly to remove dust and impurities. After draining, bottles are rotated back and transferred to the filling station.
- Filling Station Rinsed bottles enter the filling turret through the transfer star wheel. Filling valves align accurately with bottle mouths, and adopt atmospheric gravity filling principle suitable for low-viscosity non-carbonated liquids. The filling volume is controlled by precise liquid level principle to ensure consistent filling accuracy. After filling, bottles are smoothly transferred to the capping station.
- Capping Station Filled bottles are conveyed to the capping turret. The cap sorter automatically sorts and feeds caps to the capping heads. Each capping head picks up a cap and applies constant torque to tighten it onto the bottle mouth, ensuring leak-proof and uniform sealing. Finished products are finally discharged to the downstream conveyor via the outfeed star wheel.
The whole machine runs in a fully enclosed protective cover to isolate external pollution, with all stations smoothly connected to realize high-efficiency and hygienic continuous filling production.
