In cooperation with the University Goce Delchev from Stip and
the Fund for innovations and technological development, in accordance with the
call for innovation vouchers, a new software has been developed in the program
LEDER for PLC controller in the dryer for fruits and vegetables
With this project software was developed in the program "LEDER", which is
installed in the PLC controller. Recommended drying parameters (temperature,
relative humidity, air flow and drying time) for a particular crop can be set.
The user will be able to make their own fine settings. It will be installed in
agricultural fruit and vegetable dryers. The current controllers are composed of
various electrical elements such as: PWM fan speed regulator, 1-0 switches, time
relay, relative humidity and temperature controller and other components. The
main goal is to improve the operation of agricultural dryers and to obtain
numerical data on the drying process via Wi-Fi.
Increase the efficiency of our company
With the new software, our company will be more efficient in the market. We will
present a new and improved product.
Economic impact
The dryer will have a lower market price and better quality with the new
controller. The controls on the control panel will be in Macedonian. If the
dryer is intended for a market in Greece, Bulgaria or Serbia, we will change the
names of the main parameters and names of fruits in their language.
Only general symbols will be stamped on the control panel. Example: If the
client presses the F1 key, then the controller will enter the factory-set
parameters for drying organic plums. Drying of agricultural products will be
cheaper. These dryers use solar energy and electricity. energy from ESM / EVN
(clean technology).
Social impact
Farmers will be able to dry part of the harvest themselves and re-place it on
the market. Employment in the small and medium enterprises sector of
agriculture, food and processing industry will increase. Drying is also applied
to confectionery, teas and berries, mushrooms and more.
There is no pollution in the environment from the operation of the dryer. Unsold
agricultural fruits will not be thrown away. The production of food for the
needs of our country and for export will increase.
