It's nice in the dead of winter to enjoy fresh fruits - such as if they have just wood or from the garden. How do you make that delicate fruits and vegetables does not spoil?
The exhibition NTTM-81 in Moscow, our attention was attracted by a device called ION-1, created in a club of young technicians "dawn"; the city of Izhevsk: small box with rubber hose ending in a tube of Plexiglas. Designed and built the device of a ninth-grader Sasha Kalugin and the eighth-grader Sasha Akimov under the direction of engineer Vladimir Vasilyevich Tsimbalova. We were told that the fruit, processed using ion, 't go bad in a few months. Let's see, how does ION-1.
It is known that microorganisms cannot live in an atmosphere saturated with ions. Here such ionized the atmosphere and creates the device. Main part: alternator high voltage pulse type, centrifugal pump and the ionization chamber. The generator generates a voltage of about 30 kV. The pump draws air through the chamber in 100 times per second flashes a spark discharge. This little zipper separates from atoms and molecules separate electrons, i.e. creates ions. Stream of ionized air is directed into the Bank, where lie is carefully washed and dry mopped the fruits. This is the principle of operation of the ion.
And now more about it wiring diagram.
Tr - transformer with a capacity of 50-100 watts. With the winding II, stress about 300 In and with the help of full-wave rectifier turns into a pulsating unipolar. With the winding III is not the power necessary to the power of the engine, the torque of the impeller vozduhozabora. (If vozduhozabora will be able to find a low power motor with a rated voltage of 220 V, the need in the winding III will disappear and the scheme will be simplified.) In design Izhevsk guys used motor PDM-30.
Pulsating unipolar voltage is supplied to the non-polar electrode the storage capacitor 4-UF. At the same time increases the voltage at the control electrode of the discharge thyristor CON. The thyristor can be used without a radiator. The circuit is designed so that the thyristor opens at the moment when the capacitor will accumulate a voltage of about 250 V. With the rapid capacitor discharge through the thyristor and the primary winding of the automotive ignition coil (it may to be B-115 or any other ignition coil 12 In) generated high-voltage pulse. The coil can be purchased at the auto parts store. The housing of ignition coil must be connected to the common wire is "ground";. High the voltage supplied to the spark gap ionization chamber. Potentiometer 2K achieve smooth combustion of high-voltage sparks.
The ionization chamber is best made of Plexiglas. A rubber hose it connect with vozduhozabora. The electrodes are made of wire with a diameter of 1 mm and push the soldering iron into the wall of the chamber. The length of the spark gaps should be about 10 mm.
Attention! Inside the device - high voltage! Case ion must be made of an insulating material. It is strictly forbidden to open the case of the unit or disassemble it without unplugging it from the network.
So, ION is ready. Clean freshly picked fruits and vegetables in ionized air within 15-20 minutes can Now hermetically resealed the jar and before winter!
