Customized large-scale tomato sauce production line Special machinery for tomato processing plants

Description

Tomato processing line can produce from fresh tomato to different kinds of final product. The most popular is tomato paste processing line, produce from fresh tomato to tomato paste with aseptic bag in drum. That includes: fresh tomato receiving system, washing system, sorting system, extracting system, concentrating system, sterilizing system, and aseptic filling system. Then can get the tomato paste with aseptic bag in drum. And the tomato paste in aseptic bag in drum can be further produced to tomato ketchup, sauces, juice and filled in sachet, stand-up pouch, metal can, PP container, bottle, gable top, etc.

Advantages

The tomato processing line from Shanghai Gofun machinery company is running with high effective, water saving, high extracting rate, safety quality control for final product, safety control for operators, etc.

Flowchart

FRESH TOMATO ⇒ CONVEYOR ⇒ WASHING ⇒ SORTING ⇒ CRUSHING ⇒ PREHEATING ⇒ PULPER & REFINER ⇒ EVAPORATING ⇒ STERILIZING ⇒ ASEPTIC FILLING ⇒ STORAGE OR BLENDING

• Discharge Platform Upon arrival of fresh tomatoes, often transported by large trucks, manual unloading can be laborious. To address this, we have devised a discharge platform equipped with water guns for unloading tomatoes efficiently from trucks and conveying them to the processing line. Additionally, the platform serves the purpose of pre-washing the fresh tomatoes before processing begins.
• Elevator / Conveyor The elevator/conveyor system is instrumental in transferring fresh tomatoes from the exterior of the building to the processing area indoors.
• Washing Prior to crushing, a thorough washing of fresh tomatoes is essential. We employ a combination of bubble washing and spray washing machines for this task. If stringent cleaning standards are required, additional washing stages can be incorporated. Furthermore, ultrasonic and ozone cleaning techniques can be integrated for enhanced cleaning efficacy.
• Sorting Following the washing process, visually inspecting each tomato allows us to identify and remove any defective ones manually.
• Crushing The crusher operates at a speed of 1470 r/min to ensure complete crushing of fresh tomatoes.
• Preheating The pre-heater is utilized to raise the temperature of the product post-crushing, typically adjustable between 45°C to 85°C. This step enhances juice extraction rates for subsequent processes, while also safeguarding the color and flavor of the final tomato paste.
• Pulper and Refiner Running at 1470 r/min, the pulper and refiner machines employ centrifugal force to pass the product through screens, refining it. Typically, a double stage pulper and refiner setup is used, with varying screen sizes for each stage to achieve desired refinement levels.
• Evaporation Employing a Forced Circulation Vacuum Evaporator, tomato paste is concentrated under vacuum and low temperatures to preserve taste and nutrients. The resulting tomato paste usually ranges in brix levels of 28-30 and 36-38.
• Sterilization Tube-in-tube type sterilizers are employed for sterilizing the tomato paste. The sterilization temperature and holding time can be adjusted, typically heating the paste to around 115°C for 30 seconds before rapid cooling to ambient temperature to preserve taste and nutrients.
• Aseptic Filling The aseptic filling machine operates in conjunction with the sterilizer in a closed cycle system. Before production, the entire cycle undergoes sterilization to maintain an aseptic environment. Steam is utilized to safeguard the filling cavity, ensuring an aseptic filling environment.
• Storage or Blending The processed tomato paste is either stored for further use or directed towards blending processes as required.
