The bottle washing unit adopts a patented 180-degree flip-type flushing design, which has been specially upgraded to meet the hygiene requirements of tomato sauce production: empty bottles are stably clamped by high-precision stainless steel tong arms and flipped 180 degrees with the bottle mouth facing downward. Retractable high-pressure nozzles extend deep into the bottles to complete 360-degree dead-angle-free spray flushing, while the exterior of the bottles is simultaneously cleaned with multi-directional high-pressure jets. Equipped with two 5μm-precision water filtration systems, it thoroughly removes impurities from the flushing water to avoid secondary pollution during the cleaning process. After flushing is completed, the equipment automatically starts high-pressure clean air purging to completely blow out and drain residual moisture in the bottles. A hot air drying station is also available as an optional configuration to completely eliminate accumulated water inside the bottles, preventing residual moisture from mixing into the acidic tomato sauce and affecting the product's flavor and shelf life. The bottle clamping mechanism of the equipment supports stepless width adjustment, eliminating the need to replace a large number of parts, and can complete the adaptation and adjustment of bottle types with different diameters and heights within 10 minutes.

The filling unit features a modular switchable design for different tomato sauce materials, enabling rapid switching of corresponding filling components according to the type of material currently being produced: for pure tomato sauce, a standard rotor pump plus three-stage filling mode is adopted, where large-flow rapid filling is performed first, and slow drip injection is switched to when approaching the target capacity to reduce foaming of the sauce; for tomato sauce with pulp particles, replace the special large-particle flow channel and low-shear rotor pump, which will not damage the integrity of pulp particles during the filling process and avoid sauce stratification; for high-viscosity concentrated tomato sauce, start the constant-temperature heat-preserving hopper to stably control the material temperature at 35-45°C to ensure uniform fluidity of the sauce. Combined with the servo-following lifting filling head, the filling nozzle rises synchronously with the liquid level of the sauce, completely solving the problem of wall hanging during the filling of high-viscosity materials. Under all filling modes, a vacuum suction device will be activated the instant filling is completed to accurately cut off the sauce, eliminating stringing and dripping that would contaminate the bottle mouth and body.

The whole machine is designed in strict compliance with food GMP and HACCP production standards. All parts in contact with tomato sauce and cleaning water are made of food-grade 316L stainless steel, with mirror-polished inner walls that leave no sanitary dead ends. All pipe connections adopt quick-install joints, supporting docking with the CIP online cleaning system to complete deep cyclic cleaning of the whole machine without manual disassembly, fully meeting the long-term production hygiene requirements for acidic materials such as tomato sauce. The equipment is equipped with built-in intelligent detection functions of "no bottle, no bottle washing" and "no bottle, no filling". In case of missing bottles, jammed bottles, or insufficient materials, it will automatically trigger an audible and visual alarm and suspend operation to avoid idling of the equipment and material waste. All production parameters for materials and bottle types can be pre-stored in the touch control system. When switching to production of different materials, the corresponding formula can be called up with one click, eliminating repeated parameter commissioning, and the mold change efficiency is 70% higher than that of traditional equipment.

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