Profit and Comfort Energy Limited has developed an on-farm drying system for any agricultural produce, to address some of the anomalies encountered in present methods of drying/storage.
· Energy efficiency.
· Food processing techniques
· On farm process systems
With increasing agricultural produce prices, producers are realizing the significant cost of losses due to poor silo practice. Simply blowing ambient air through any larger quantity of nuts will not guarantee uniform dryness, and re-wetting is a common result.
Thereare many parallels in quality products drying, both are dried at similar temperatures, and at carefully controlled rates of moisture loss.
Our expertise is in carefully monitoring ambient and system temperature & RH, and by managing venting and heat input, we are able to control very finely the rate of moisture loss, and keep energy use to a minimum.
We are aimed at utilizing skills in innovative process development and the establishment and continued development of renewable energy technologies to complement and enhance its skills in providing employment opportunities and wealth creation.
We are also able to advise on and implement actions in areas where there are potentials for export products.
Our systems have found acceptability and relevance with individuals, state government and international agencies like IITA, UNIDO etc.
We have renewable energy systems for food security like:
- Natural convection solar dryers
- Forced convection Multi Solar dryer (FOMSOD 66)
- Solar powered post – harvest processors
For solving environmental degradation like:
i. Solar generator
ii. Wind turbines
iii. Solar Refrigerator
iv. Solar Cookers
FOMSOD BC 66
An array of solar photovoltaic panel is mounted on the roof of the FOMSOD 66 or on an adjacent building. Air is pumped in a closed circuit between the collectors and the heat exchanger inside the system. Heat is extracted from the air which then returns to the exchanger for re-heating.
The circuit involves a "Day" and "Night" loop with a diverter valve controlling the direction of the air flow according to the commands of the Differential Temperature Controller. An auxiliary air heater is incorporated in the circuit to "top up" the temperature if required. In the standard format this is the indirect fired gas unit, but any external heat source could be used. Gas can be used to bring the system to temperature where it is maintained by the solar circuit with occasional top ups from the gas auxiliary.
FOMSOD 66 can also be run using Solar heating alone if required.
An automatic PLC controller allows a full range of schedule options where any system climate can be achieved. Humidity control is maintained by a balance between venting and fogging.
