Automatic Glass Bottle Washing Machine for Ketchup Filling

Product Details
This fully automatic integrated machine combining glass bottle rinser and tomato sauce filler is an exclusive custom-developed combined unit tailored for mass tomato sauce production scenarios. It efficiently links the two core processes of glass bottle cleaning and tomato sauce filling, realizing full automatic operation from empty bottle feeding to sauce filling. The equipment completely addresses long-standing industry pain points in traditional tomato sauce production, such as incomplete bottle cleaning, sauce residue on bottle bodies after filling, and particle breakage, drastically elevating the hygiene level and production efficiency of tomato sauce products.

The bottle rinsing unit adopts a patented 180° inverted flushing design. Empty bottles are precisely gripped by high-precision stainless steel tong arms, flipped 180° with the bottle mouth facing downward, while high-pressure nozzles extend deep into the bottles to complete 360° dead-angle-free spray rinsing. Meanwhile, the exterior of the bottle body undergoes synchronous high-pressure cleaning. Equipped with two sets of micron-grade water filtration systems, it effectively removes impurities in the rinsing water to avoid secondary contamination during the cleaning process. After flushing is completed, the equipment automatically activates a high-pressure clean air purge to thoroughly blow out and drain residual moisture inside the bottles, preventing residual water from mixing into the tomato sauce and compromising product flavor and shelf life. The variable frequency speed regulation system flexibly adapts the flushing duration for different bottle types, enabling compatibility with multiple specifications of tomato sauce glass bottles without replacing a large number of components.

The filling unit has undergone in-depth special optimization targeting the material properties of tomato sauce. It adopts a food-grade specialized rotor pump metering structure for sauces, with optimized flow paths specifically designed for tomato sauce containing tomato seeds and pulp particles. No particle integrity will be damaged during the filling process, preventing sauce stratification that would affect the mouthfeel. The equipment is equipped with a two-stage intelligent filling mode: it first performs high-flow rapid filling, and automatically switches to slow drip filling mode when approaching the target volume. Paired with a servo-following lifting filling head where the filling nozzle rises synchronously with the rising sauce liquid level, foaming of the sauce and residue on the inner bottle wall are greatly reduced. A vacuum suck-back device is activated the instant filling is completed, completely eliminating stringing and dripping of tomato sauce, preventing contamination of the bottle mouth and body, and clearing obstacles for subsequent capping and labeling processes.

The complete machine is designed in strict compliance with food GMP production standards. All components in contact with tomato sauce and cleaning water are made of food-grade stainless steel, all pipeline connections adopt quick-fit joints, and the inner walls are mirror-polished without any hygiene dead zones, which can effectively prevent residual tomato sauce from oxidizing and deteriorating. It supports connection with a CIP (Clean-in-Place) system, enabling thorough deep cleaning of the entire machine without manual disassembly, fully meeting the long-term production hygiene requirements for acidic materials such as tomato sauce. The equipment comes with built-in intelligent detection functions that prevent bottle rinsing without a bottle and prevent filling without a bottle. In case of missing bottles or bottle jams, it will automatically trigger sound and light alarms and pause operation, avoiding idle equipment operation and material waste. All operating parameters can be visually adjusted on the touch screen, which can store 30 sets of production formulas for different bottle types and filling specifications. When switching between products, the corresponding formula can be called up with one click without repeated parameter debugging.

The equipment can independently complete the bottle rinsing + filling process as a standalone unit, or be connected to a capping machine, labeling machine, and pasteurization equipment to form a complete fully automatic tomato sauce filling production line, realizing fully unmanned operation from empty bottle input to finished product output. Its average mean time between failures (MTBF) reaches over 8000 hours, fully meeting the diverse capacity demands ranging from small and medium-sized tomato sauce processing plants to large-scale standardized fruit and vegetable sauce manufacturing enterprises.

 Frequently Asked Questions
Can this equipment fill tomato sauce containing tomato seeds and pulp particles?
Yes. The equipment adopts a specialized rotor pump structure for sauces, with optimized flow path design for particulate materials. It will not cause particle blockage, nor damage the integrity of tomato seeds and pulp, delivering a stable and smooth filling process.

Tomato sauce is an acidic material. Will the equipment suffer from corrosion issues after long-term use?
All components in contact with tomato sauce are made of 316L food-grade stainless steel with upgraded anti-corrosion treatment specifically for acidic materials. No corrosion or substance precipitation will occur even after long-term tomato sauce filling, which fully complies with food production safety standards.

Is it troublesome to perform format changeover and debugging for tomato sauce glass bottles of different specifications?
The bottle gripping mechanism of the equipment supports quick width adjustment. Combined with pre-set production formulas, the bottle type switchover can be completed in just over ten minutes, without requiring long-term shutdown to disassemble a large number of components, adapting to the flexible production demand of multi-specification tomato sauce products.

Will the residual moisture inside the bottles after rinsing affect the shelf life of tomato sauce?
After bottle rinsing, the equipment will perform deep purging and draining via high-pressure clean air, leaving almost no residual water in the bottles. A hot air drying station can also be optionally equipped to completely eliminate moisture residue, which will not affect the flavor and shelf life of tomato sauce.

Tomato sauce is viscous and prone to residue. Is the equipment easy to clean and maintain?
All components in contact with materials adopt quick-fit structures that can be quickly disassembled for rinsing. It also supports optional CIP clean-in-place system, enabling full-machine circulating cleaning without disassembly, avoiding oxidized and caked tomato sauce residue from clogging the pipelines.

What about the after-sales support of this equipment?
The complete machine is covered by 1-year free warranty, and extended warranty services are available for core components. Remote online diagnosis can resolve over 80% of daily technical issues. For complex faults, engineers can quickly arrive on site to carry out installation and commissioning. Meanwhile, complete equipment operation and daily maintenance training will be provided for operating personnel.
