System Engineering Description & Technical Scope

Plant Architecture
Tomato Paste Solutions

Hadof Machinery delivers world-class industrial tomato processing lines with capacities ranging from 2 T/h to over 50 T/h fresh fruit intake. The process incorporates hydraulic flume unloading, sorting, crushing, enzymatic cold/hot break deactivation, two-stage turbo pulping & refining, continuous forced-circulation MVR/multi-effect vacuum evaporation, tubular sterilization, and aseptic bag-in-drum filling.

Key System Features

  • Hot Break / Cold Break Flexibility: Controlled enzymatic inactivation preserves pectin for high-viscosity paste (Bostwick < 4cm/30s).
  • Forced Circulation Evaporation: High-efficiency concentration under low temperature prevents burnt flavors and dark discoloration.
  • Aseptic Filling: 220-liter aseptic bag packaging ensures 2-year ambient storage stability without preservatives.

Verified SUS304 Builds

Featured sanitary machinery and turnkey workshop integration units custom fabricated for Tomato Paste Solutions. Precision engineered for high continuous yield and zero cross-contamination:

Sanitary Vacuum Deaeration & Concentration Unit Unit 01

Sanitary Vacuum Deaeration & Concentration Unit

Rapid degassing under negative pressure eliminates micro-air bubbles to preserve deep natural red color.

Planetary Stirring Steam Jacketed Sauce Kettle Unit 02

Planetary Stirring Steam Jacketed Sauce Kettle

Teflon scrapers sweep 100% of kettle inner surface to prevent paste burning during high-temp cooking.

Heavy-Duty Tubular Forced Circulation Evaporator Unit 03

Heavy-Duty Tubular Forced Circulation Evaporator

Low-temperature concentration preserves high natural Brix, vibrant red color, and natural pectin yield.

End-to-End Processing Flowchart & Stage Pipeline

Automated Continuous Flow

The processing line operates as an uninterrupted sanitary sequence. Raw agricultural produce transitions through sequential mechanical, hydraulic, and thermal treatment zones synchronized by Siemens variable-speed frequency drives:

STAGE 01

Flume Soaking & Infeed

Input: Field Harvest Trucks

Heavy sediment settling flume separates rocks and soil clumps from raw tomatoes through hydraulic buoyancy.

STAGE 02

Roller Inspection & Trimming

State: 100% Ripe Selected Fruit

Rotating stainless steel roller inspection conveyors allow sorting operators to cull green or defective fruit.

STAGE 03

Hot-Break / Cold-Break Chopper

State: Crushed Seed & Pulp Slurry

Rapid thermal tubular inactivation of pectin enzymes preserves high natural viscosity and vibrant red color.

STAGE 04

Double-Stage Turbo Pulper

State: Pure Strained Puree

High-speed rotary scraper blades force tomato pulp through fine sieves while discharging skins and seeds separately.

STAGE 05

Forced Circulation Evaporator

State: Concentrated 28-38% Brix

Multi-effect falling film and forced circulation vacuum evaporators concentrate purees at low thermal degradation.

STAGE 06

UHT Sterilization & Aseptic Fill

Output: 220L Aseptic Bags in Drums

Flash tubular sterilization at 115°C followed by high-barrier aseptic valve filling into export steel drums.
