PLC Based Ripening Systems

Potato Mushroom Controller
  • The Most Advanced ripening controller with complete Ripening Management Software
  • RS 485 based Digital sensor transmission for precise value
  • Integrated chamber conditioning features
  • Four dedicated Ripening processes, Precool, Dose, Vent and Holding
  • Universal communication (RS 485/Ethernet) for integration with other control systems
  • Fruitron Ripening Management System is the state-of-the-art ripening management controller that is highly efficient in fruit ripening in terms of power consumption and gas usage. The entire process is automated with sensors and proprietary logic which yields premium ripened fruits with minimal labour dependency
  • The complete ripening process is data logged onto a USB drive, HMI also generates trends and records every component working hours for regular maintenance. The controller can also be hooked up to a GPRS modem and the data can be populated onto a web server by which the user can monitor the chambers from any internet device
  • The colour of the fruit changes as per the ripening stage which gives a clear indication of the ripening status. There are Alarms and Indicators present in the display where the process parameters are indicated, alarms are activated if any deviation of the process is identified. A user can convey the acknowledgement of an alarm using the touch screen & also by the hardware switches on the panel
  • The intuitive touch display has been designed to show the user all the information of the process on a single screen. The display indicates Temperature, RH, CO2 and Ethylene values according to the process
  • Upto 30% energy efficient in ripening temperature control
  • Process based temperature control
  • Temperature control on ambient sensor, pulp sensors or on return line sensors
  • Degree Celsius or Degree Fahrenheit mode
  • Dual compressor logic with smart switching
  • Independent indoor fan control
  • Interval and time based Defrost
  • Auto-process shutoff when chamber door is open for better efficiency and heat losses
  • Up to 3 predefined recipes for universal application and 1 user programmable manual recipe
  • Process based Temperature and RH control
  • Smart Ethylene injection based on chamber size and quality
  • Precise CO2 Control
  • Fuzzy logic failsafe for Ethylene and CO2 control on sensor failure
  • Run time programmable temperature and RH control for target fruit
  • User controlled CO2 control range
  • User controlled ripening duration
  • Provision for making user based recipe
  • User controlled Ethylene injection control range
