A knowledge-based company has developed an agricultural spraying device that can also be employed for environmental disinfection through thermal fogging for the first time in Iran.
The decision to circumvent the Covid-19 pandemic required the import of a large number of such machines, but domestic models were modified after research to handle medical disinfection, alongside their agricultural functions.
“Thermal fogging machine disperses the spray material in the form of fog with dimensions of 5-50 microns,” Abazar Vahdat, the CEO of knowledge-based Sepid Pajuhan Pars Company, was quoted as saying by the news portal of Vice-Presidency for Science and Technology.
The machine is designed in two models that can be attached to the back of a van or a car.
The best way to repel greenhouse pests and various plant diseases is the fogging method and any type of water-soluble pesticide can be used in such machines. The new model has also reduced the spraying time compared with traditional methods.
In addition to disinfection, this thermal machine has other features such as generating humidity in the greenhouse, preventing frost and blocking the invasion of fungi, insects and small animals in silos and warehouses.
Every year, some crops suffer from frost damage. The methods used in Iran to deal with this problem are expensive and inefficient, but this device creates a layer of fog that shields the plants from frost damage.
Some small pests such as whiteflies or thrips were not destroyed by the previous spraying method and this caused problems for greenhouse owners. This device has solved this problem with its special mode of spraying and reduced pesticide consumption in the agricultural sector by 80%. A mist produced by the machine can also be used to prevent infectious diseases such as leishmaniasis.
This product significantly reduces the cost of equipment and manpower, while reducing 99% of water consumption required for spraying. It carries a 10-year warranty on parts and services and, a one-year warranty on engine and main parts.
Heat sprayers have been exported to Armenia and Azerbaijan, but as only Iran and Turkey possess the knowhow to produce this machine in the region, it has high export potentials.
Multifunction Transducer Developed
A knowledge-based company has designed and manufactured a multifunction transducer that can be used to monitor the power grid in large and small industrial complexes.
“In digital devices, especially digital measuring devices, one of the most important concerns is how to deal with an analog quantity,” Mohammad Reza Hashemi, CEO of Farayand Niroopardaz Company, said.
Hashemi pointed out that the multifunction transducer is based on the latest electronic technology, the Vice-Presidency of Science and Technology reported.
The main function of transducers is to convert one type of energy into another. There is no limit to the type of energy, as they convert each of the electrical, chemical, mechanical and thermal forms of energy.
Transducers are one of the main equipment in industrial electrical automation systems that can be used to sample power grid parameters and convert them into standard signals.
Electrical parameters in this transducer are calculated after the conversion to a digital signal. These are stored instantly in the system’s memory and can be recalled or applied to current or voltage analog outputs after digital selection by all isolated analog-to-analog converters.
Online network monitoring features, measurement of more than 120 electrical parameters of the power grid, remote measurement capability, 2 kV isolation between all parts and four isolated analog current and voltage outputs are among the special features of this domestic transducer.
It offers protection against short-circuit output, measures the total voltage, one-way or two-way active frequency, tolerates transient inputs up to several times the nominal values, has an internal clock equipped with a backup battery and a solar calendar with detectability, synchronization with location systems and occupies little space.
“Knowledge-based companies need to enjoy benefits such as tax breaks to boost domestic production,” the CEO of the knowledge-based company said, while noting that about 15 jobs have been created in the production process.
“The foreign counterpart of the multifunction transducer is priced 12-fold higher and not economical for domestic companies. For this reason and in order to prevent unnecessary imports, knowledge-based companies should be supported.”
