Tomato Ketchup Processing Line

Industrial Turnkey Tomato Ketchup Processing Line (2000 kg/h)

Manufacturing high-quality tomato ketchup on an industrial scale requires precise thermal profiling to prevent lycopene degradation while maintaining strict rheological properties. The primary engineering challenge in tomato processing is deactivating pectin-destroying enzymes rapidly to secure high viscosity, preventing serum separation (syneresis) during extended ambient storage. Our fully integrated, continuous tomato ketchup processing line manages the entire sequence from raw fruit washing to final formulation, concentration, and thermal pasteurization. Configured for a raw intake of 2,000 kg/h, this Turnkey facility ensures a consistent Bostwick consistency and standardized 28-30% Brix output, engineered strictly to CE and HACCP sanitary guidelines.

• Production Capacity: Processes 2,000 kg/h of raw tomatoes, yielding approximately 400 to 450 kg/h of standardized ketchup (based on 30% final Brix).
• Wetted Materials: All fluid-contact vessels, tubular heat exchangers, and mixing tanks are fabricated from SUS316L stainless steel, mitigating corrosion from natural citric and acetic acids.
• Thermal Efficiency: Integrates a forced-circulation vacuum evaporator that concentrates the puree at lower temperatures (65°C - 70°C), preserving natural color and reducing industrial steam consumption.

Core Engineering Advantages for Rheological Stability

Producing a condiment with stable shear-thinning properties means mechanical force and thermal exposure must be calculated meticulously. We engineered this line to target the exact processing friction points encountered when blending concentrated tomato paste with vinegar, liquid sugars, and spice particulates.

• Enzyme Deactivation via Hot Break: A dedicated tubular pre-heater instantaneously raises the crushed tomato mash to 90°C. This immediate thermal shock deactivates pectinesterase and polygalacturonase, locking in natural pectins to guarantee a thick, premium mouthfeel without relying heavily on artificial hydrocolloids.
• Low-Temperature Vacuum Evaporation: Operating under a negative pressure of -0.08 MPa, the forced-circulation evaporator removes excess water at roughly 68°C. Bypassing atmospheric boiling prevents sugar caramelization, ensuring the ketchup retains a vibrant, naturally bright red color.
• High-Pressure Homogenization Integration: Prior to final pasteurization, the formulated ketchup is forced through a two-stage homogenizer at 15 to 20 MPa. This intense mechanical shear reduces the tomato fibers to micro-particulates, permanently binding the water and cellular matter to eliminate fluid pooling inside the bottle.
• Automated CIP Integration: The entire piping matrix incorporates zero-dead-leg pneumatic valves and connects to an automated Clean-In-Place station. This permits sequential acid and alkali flushing without mechanical disassembly, securing microbial safety between batch changeovers.

To establish a fully automated commercial output, the product must be transferred seamlessly from the pasteurizer into sterilized packaging. The discharge of our tubular pasteurization unit is specifically calibrated to feed directly into an automated liquid filling machine, maintaining holding temperatures above 85°C to execute strict hot-filling protocols for glass bottles or PET containers.

Process Flow and Mechanical Structure Dissection

The continuous operation relies on synchronized fluid dynamics. Initially, flume washing and roller sorting mechanisms remove field debris and defective fruit. A high-capacity hammer mill then executes the primary size reduction, instantly discharging the mash into the Hot Break tubular heat exchanger to halt enzymatic breakdown.

Following thermal treatment, a double-stage pulper/refiner mechanically separates the seeds and skin from the serum. The first stage utilizes a 1.2mm perforated screen, while the secondary refiner employs a 0.6mm screen, ensuring an exceptionally smooth puree base. This refined base is pumped into the vacuum evaporator until the base Brix reaches the formulation target.

In the compounding phase, load-cell mounted SUS316L blending tanks receive the concentrated puree alongside metered doses of acetic acid, liquid sucrose, and spice slurries. Agitation is handled by variable-speed scraped-surface anchor mixers, which physically sweep the tank walls to prevent localized burning of high-sugar ingredients. The completed mixture is then pasteurized in a concentric tube-in-tube heat exchanger at 95°C for 30 seconds before being diverted to the filling buffer tank.

Industrial Use Cases in Continuous Condiment Facilities

Operating a 2,000 kg/h plant demands robust utility synchronization. In facilities executing 16-hour continuous shifts, the accumulation of organic fouling inside heat exchangers typically forces production halts. Our system utilizes oversized, highly polished corrugated inner tubes within the pasteurizer module to drastically reduce the fouling coefficient, extending the continuous processing window before a CIP cycle is mandated.

Furthermore, the central Siemens PLC control architecture provides plant engineers with absolute transparency. Automated Brix refractometers and inline flow meters transmit live data to the HMI. If the final pasteurization temperature drops below the critical 95°C threshold, a pneumatic flow-diversion valve automatically loops the ketchup back into the holding tank, physically preventing unsterilized product from entering the packaging hall.

Global Compliance and Manufacturer Support

Food processing infrastructure processing acidic commodities must be manufactured to exacting global standards. All internal welding seams undergo argon-shielded TIG welding and subsequent chemical passivation to restore the chromium oxide layer, effectively eliminating micro-crevices. The electrical panels are constructed using CE-marked contactors, overload relays, and shielded cabling. Our technical teams provide comprehensive site layout engineering, utility consumption mapping, and Turnkey Installation & Commissioning (I&C) services, ensuring the deployed system meets FDA and GMP directives right on the factory floor.
