Bottle Washing Machines

Water – based Bottle Washing Machine

The water – based bottle washing machine is suitable for cleaning most regular bottles used for sauces, soy sauce, and vinegar. It uses a high – pressure water spraying system to thoroughly flush out impurities, dust, etc. from both the inside and outside of the bottles. The water – washing process consists of three stages: pre – washing, main washing, and rinsing. In the pre – washing stage, low – pressure water is used to initially wash away larger particulate impurities inside the bottles. During the main washing stage, high – pressure water combined with special food – grade cleaning agents is employed to powerfully remove stubborn stains. In the rinsing stage, clean water is used to completely wash the bottle body to ensure no cleaning agent residue. The water – based bottle washing machine is equipped with an efficient water circulation system, which can filter, purify, and reuse the cleaning water, effectively saving water resources. Meanwhile, to ensure the cleaning effect, there are multiple multi – angle nozzles inside the water – based bottle washing machine to guarantee that all parts of the bottle body can be fully cleaned.

Air – based Bottle Washing Machine

For packaging bottles of special liquid products that cannot come into contact with water, such as some high – end honey bottles and bottles for water – soluble sauces, the air – based bottle washing machine is an ideal choice. The air – based bottle washing machine uses high – pressure air to blow out dust and impurities from the bottles through special blowing nozzles. It adopts an advanced air filtration system to ensure that the air entering the bottles is clean and sterile, avoiding secondary pollution. The air – based bottle washing machine is also equipped with an automatic sensing device, which can automatically adjust the position of the blowing nozzles and the intensity of the air jet according to the size and shape of the bottles, ensuring consistent cleaning results. In addition, the air – based bottle washing machine operates with low noise, meeting the environmental requirements of food production workshops.

Filling Machines

1.For High – viscosity Liquids like Sauces, Chili Sauces, and Butter

For high – viscosity liquids such as sauces, chili sauces, and butter, we use piston – type filling machines. The piston – type filling machine sucks the liquid from the material tank and precisely injects it into the bottles through the reciprocating motion of the piston. Its filling accuracy can reach ±1%, which can meet the requirements of different packaging specifications. To ensure the smooth flow of high – viscosity liquids, the filling machine is equipped with a heating and insulation device, which can control the liquid temperature within an appropriate range to reduce the viscosity for easier filling. Meanwhile, the filling head of the filling machine has a special design to prevent the sauce from sticking to the wall and dripping, ensuring a clean production environment.

2.For Low – viscosity Liquids like Soy Sauce and Vinegar

For low – viscosity liquids such as soy sauce and vinegar, the gravity – type filling machine is the best choice. The gravity – type filling machine uses the self – gravity of the liquid and realizes quantitative filling by controlling the opening and closing of the filling valve. This type of filling machine has a simple structure, a fast filling speed, and an accuracy of up to ±0.5%. To avoid foam generation during the filling process, the filling machine uses a submerged filling head, allowing the liquid to flow slowly into the bottle and reducing the impact. In addition, the filling machine is equipped with a liquid level control system to ensure that the filling liquid level of each bottle is consistent.

3.For Particulate or Semi – fluid Liquids like Ketchup and Honey

For particulate or semi – fluid liquids such as ketchup and honey, the screw – type filling machine is suitable. The screw – type filling machine pushes the liquid forward through the rotation of the screw to achieve quantitative filling. It can effectively handle liquids containing particles, ensuring the uniform distribution of particles without clogging the filling head. The rotation speed of the screw can be precisely adjusted according to the viscosity of the liquid and the filling volume, and the filling accuracy can reach ±1%. At the same time, the filling machine uses a smooth pipeline design inside to reduce liquid residue, facilitating cleaning and maintenance.

Capping machine and capping machine

Capping machine
The capping machine is mainly used for capping products such as sauce bottles and honey bottles. It uses advanced torque control technology to ensure that the bottle cap is tightened with just the right force. It not only ensures the sealing of the product, prevents leakage of sauces, honey, etc., but also facilitates consumers to open. The capping speed of the capping machine can be adjusted according to production needs. During the capping process, the position and state of the bottle cap are detected by the photoelectric sensor. For products that are not tightened or the bottle cap is missing, it can be automatically rejected to ensure product quality.

Screw capping machine
The capping machine is suitable for some products that need to be capped and sealed, such as some high-end soy sauce and vinegar bottles. The capping machine presses the bottle cap firmly on the bottle mouth by precisely controlling the pressure. It can adapt to bottle caps of different materials and shapes, such as metal caps, plastic caps, etc. The capping speed is fast and the efficiency is high. At the same time, the capping machine is equipped with an automatic capping device to improve the degree of production automation and reduce manual intervention.

Labeling Machines

We specialize in four types of labeling systems: pressure-sensitive labelers, sleeve label applicators, hot-melt OPP label machines, and cold-glue paper labelers. While we provide the machinery only (labels must be sourced separately), we offer optional label procurement support. Machine selection depends on bottle shape/size and label placement requirements, such as single-side (round/flat bottles), dual-side, triple-side, front/back dual labels, or multi-label configurations. Our labeling systems integrate seamlessly with coders (for date printing) and connect via conveyor belts to fillers or shrink wrappers. We tailor recommendations based on production speed, container design, and label dimensions. Label artwork must be supplied by your printing partner.

Palletizer Units, Stacking Pallet Feeders, and Pallet Stretch – Film Wrapper

Palletizer:

This equipment is designed to pick up the bottle packages wrapped with film one by one and stack them onto pallets. The pallets are provided automatically by the pallet feeder. Once a stack of bottles is successfully palletized, it is transferred to the turntable of the pallet stretch – wrapping machine by means of rollers. Once the photoelectric sensor senses the arrival of the pallet, the turntable starts to rotate, and the stretch film is wrapped around the stacked bottles. This ensures the stability of the bottle stack during transportation, minimizing the risk of bottles falling and enabling easy forklift transportation to supermarkets. Palletizers come in different forms. Some use pneumatic suction, while others employ robotic arms for gripping. In terms of structure, there are column – style and gantry – style models. The column – style is appropriate for small – scale production lines, and the gantry – style, with its higher stability and load – bearing capacity, is ideal for large – scale production lines.

Pallet Feeder:

The pallet feeder has the function of automatically distributing pallets. A pallet serves as the tray at the bottom of the stack to support the bottles. In cases where the customer needs separator boards, an additional machine is necessary. Although placing the bottom pallet and separator boards can be carried out manually, the use of automated equipment can enhance efficiency and cut down on labor costs.

Pallet Stretch – Wrapping Machine:

Pallet stretch – wrapping machines are classified into two types: self – rotating pallet stretch – wrapping machines and non – rotating pallet swing – arm stretch – wrapping machines. When the pallet remains stable during self – rotation, an automatic stretch – wrapping machine can be a good choice. However, if the pallet is extremely high and self – rotation might lead to item dropping, a non – rotating pallet swing – arm stretch – wrapping machine should be opted for. The swing – arm stretch – wrapping machine winds the stretch film around the pallet by rotating its swing – arm, making it suitable for high – stacked pallets or pallets with irregular shapes.
