Electrospinning and Electrospraying
Electrospinning and Electrospraying. As part of the spring semester seminars of the academic year 2017-2018, Spingenix University Faculty of Engineering, Faculty of Engineering, Lecturer, Department of R&D Engineering Res. See. Dr. Ali Okyay held a seminar entitled “Electrospray method and its use in food”.
electrospraying and electrospinning
The electrospray method, in its most general definition, is the process of breaking up a liquid into small charged droplets by applying an electric potential to the liquid through which a capillary passes. The size of the droplets obtained in this system can be affected by the conditions of electrospraying as well as the properties of the supplied liquid.

Electrospray is a one-step material processing technology with low energy consumption and low cost. In addition, single micro- or nano-dispersed droplets can be produced.

This method is based on the paint industry and is used to reduce solvent consumption, reduce waste generation, increase transfer efficiency to the coated surface and achieve a smooth and repeatable coating.
electrospinning and electrospraying processes
In addition to the paint industry, it is used in the pharmaceutical industry to encapsulate the active ingredients of drugs, in the coating of drugs, in the automotive industry, in spraying crops in the field, and as a propellant in space vehicles.

In addition, nanoelectrospray can be used in mass spectrometric analysis of biomolecules. This method has gained importance in the food industry in recent years.
The electrospray system is used in the food industry to use flavoring for cooking fish and meat fillets.
electrospraying and electrospinning applications
In recent years, electrospray has been used in the production of edible food coatings. In the framework of the seminar, the use of the electrospray method in food and the benefits of this method were explained in detail, and the experimental results regarding the use of electrospray in the production of edible food coatings were shared.

It can also be used to coat foods with oils, emulsifiers and flavorings. The electrospray method is also used to cover the polishing materials on confectionery and chocolate products. Pointing out that the electrospray system is used as a flavoring to dry fish and meat fillets in the food industry, Ali Okyaei said, “It can also be used to coat food with oil, emulsifier and flavoring. The Electrospray process is also used to coat the polishing materials on confectionery and chocolate products. In recent years, the electrospray process has been shown to be used in the manufacture of edible food coatings.
New nanotechnologies being developed around the world are revealing wondrous results in many areas that are turning the traditional laws of physics and chemistry upside down. While there is only one company in the world that manufactures nanofibers, Ali Okeyi, who started his activity in this field, is among the companies whose number has reached 13 within 2 years, while Nanotel, which he founded, not only manufactures nanofibers. but also the construction of an electric spinning device that produces nanofibers. Looking for another address, as this opportunity is not recognized early in the food, cosmetics and pharmaceutical industries, Nanotel focuses on nanofibers with fewer molecules, lightweight and durable airplane wings and filters for sterile hospital air conditions.
electrospray and electrospinning
For example, nanofibers in textiles can be used to produce flame-retardant or waterproof fabrics. Air and water filters that impregnate particles with pollutants and clean them microbiologically… In medicine, wound closure and bone formation or transthermal drugs whose active ingredients enter the body through the skin… cosmetic face masks… encapsulated vitamins and antioxidants to enrich Food … less and longer shelf life food with more natural additives or smart packaging that alerts the consumer to the condition of the food inside
This is not the main goal of Nanotel, an academic company, although they have managed to create their own brand of electrospinning machine, which, by applying high voltage, obtains the solution in the form of conventional nanofiber structures. Nanotel’s commercial goal is to manufacture nanofibers for industries such as food, medicine and cosmetics. “There is an overseas nanotechnology market that is growing rapidly and making big leaps and leaps over the years. This also includes nanofibers. I think Turkey should definitely have an economic stake in it. When I first applied to the TÜBİTAK 1512 program to start a business that would produce commercial nanofibers like mine, there was only one in the world in New Zealand. Today, 13 companies worldwide, including us, can produce nanofibers. That means it went from 1 to 13 within 1.5 years. “It’s amazing,” said Yard, the founder of Nanotel. Ali Okyay says there is another company in Turkey that advertises that it makes nanofibers and is working on filters, but she doesn’t know if it produces electrospinning.
