System Engineering Description & Technical Scope

Plant Architecture
Fresh Fruit Sorting and Waxing Solutions

Our post-harvest fresh fruit handling line is engineered to significantly boost export value and shelf life of citrus, apples, pears, and stone fruits. From orchard crate tipping, hot water fungicide soaking, high-pressure soft brush scrubbing, food-grade thermal wax spraying, tunnel drying, to high-speed multi-lane electronic weight and optical grading.

Key System Features

  • Uniform Wax Atomization: Ultra-fine high-pressure nozzles provide micro-thin, glossy, food-safe protective coating.
  • Electronic Dynamic Weighing: Accuracy within +/- 1g at sorting speeds up to 15 fruits per second per lane.
  • Soft-Drop Discharge: Specialized air-cushioned chute transitions eliminate impact bruising on delicate fruit skin.

Gentle pneumatic tipping cups transfer graded citrus and apples into soft-drop packaging tables.

High-Speed Sizing Infeed Conveyor System Unit 03

High-Speed Sizing Infeed Conveyor System

Vibration alignment belts orient single fruits to prevent skin scratching before optical scanning.

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

Cushioned Flume Infeed

Input: Orchard Harvest Crates

Water flume tipping tank eliminates mechanical drop damage while pre-soaking field dust and leaves off fruit peel.

STAGE 02

High-Pressure Brush Cleaning

State: Spotless Clean Fruit

Natural horsehair and food-grade PE brush rollers with high-pressure oscillating water spray bars scrub stubborn stains.

STAGE 03

Circulating Pre-Drying Tunnel

State: Moisture Evaporated

High-velocity warm air blowers dry peel surface completely to ensure even, uniform food-grade wax absorption.

STAGE 04

Ultrasonic Wax Atomization

State: Micro-Thin Carnauba Coat

Precision atomizing nozzles apply a breathable natural wax coating that prevents internal dehydration and decay.

STAGE 05

Thermostatic Curing Tunnel

State: High-Gloss Protective Seal

Low-temperature curing tunnel dries wax instantaneously, imparting high supermarket luster and sealing pores.

STAGE 06

Electronic Weight/Diameter Sizer

Output: Graded Export Cartons

High-speed load cells and optical sensors sort produce across 6–10 calibrated grade channels into packing tables.
