PLC Based Automatic Ripening Systems

Fruitron 2.0

Dedicated automatic PLC based ripening controller for 1 room.

Automated solution by Chemtron, best suited for ripeners targeting premium quality ripened fruits with precision control datalogging.

This solution is best suited for ripening chambers of 12 to 40 tons of fruit capacity.

The controller controls temperature, RH, Ethylene and CO2 based on sensor feedback which ensures repetitive and most efficient ripening process.


Features:
  • One dedicated controller with colour touch interface with trends, graphs and USB data logging
  • Two independent indoor fan control, 2 compressor control
  • Three pre-set fruit ripening recipe and 1 manual recipe
  • Four defined process precool, dosing, venting and post cool
  • Defrost and compressor protection logic
  • Energy saving by smart control logics
  • Audio visual alarms
  • Auto fall back to time based operations if sensor fails
  • SCADA monitoring possible



Specifications:
  • Enclosure: SS316
  • Mount: Wall
  • Input: 230 VAC, 50 Hz.
  • Control output: 230 VAC
  • Number of control output: 8 per room

Parameter Monitor Control
Temperature Ambient Temperature with range 0 to 50 degC. Pulp Temperature (upto 4 probes) which can be inserted into the fruit. Controls up to 2 indoor units and 2 outdoor units.
Can operate solenoids for Ammonia based refrigeration.
Relative Humidity Ambient RH between 10 to 98 % Operates humidifiers which are controlled by sensor feedback and hysteresis logic.
Ethylene Measures Ethylene in the range 0 – 200 ppm. Operates Gas Dispensing Unitsthat releases desired Ethylene into the ripening chambers.
Carbon Dioxide Measures CO2 in the range 0 – 3.2%. Operates CO2 and fresh air dampersto remove the excess CO2 build up in the chamber.
