From puppetsock's reply to Is it possible to build a black hole (kugelblitz) gun?, it seems like a black hole of 228 tonnes evaporate after just 1 second. And the lifetime of a black hole in general is proportional to the cube of its mass.
Edit: Clarifying my thought process:
No, this is unfortunately impossible.
The key here is that Hawking radiation bears no resemblance to the constituent matter that formed the black hole (this turns out to be a bit of a problem - see the black hole information paradox for more details). Black hole evaporation dramatically favors the production of lighter particles. For example, a black hole of temperature $T=100\;\text{GeV}\approx10^{15}\;\text{K}$ emits less than 3% of its emitted energy in the form of protons and antiprotons (see MacGibbon & Webber 1990). Over three quarters ends up as photons and neutrinos, with most of the remainder in the form of electrons and positrons.
As a rule of thumb, for a particle of mass $m$, a black hole needs to have a temperature $T$ such that its thermal energy $E_T\approx k_BT$ is on the order of $mc^2$ for that particle to be emitted significantly. Hence, hotter (read: less massive and closer to death) black holes may emit more massive particles, but the majority of their emission should still take the form of neutrinos and photons.
The upshot of all of this is that the mass of any object that travels inside the event horizon will reemerge in a form completely different from the original - dump a block of cheese into the black hole, and it won't emerge as anything like the original mixture of protons, neutrons and electrons, let alone a block of cheese.
A black hole that explodes within the next second is of subatomic size. Anything that falls in must get atomized before it crosses the event horizon.
And anything that approaches will be ripped apart long before it reaches the event horizon due to the Hawking radiation that's coming out of the black hole. This radiation pressure makes feeding such a small black hole virtually impossible. It would even explode if it were embedded in the core of the sun. Once a black hole's radiation reaches a certain level, the only thing you can do is to flee if you don't want to be blown up with it. It's the perfect ticking time bomb, with a strength that dwarves all the nukes that we have built.
No
An object doesn't quite 'fall' into a black hole, a more correct explanation would be that it forms an accretion on the hyper-dense mass which forms the black hole. It doesn't matter how little time an object spends in a black hole, once it's there, it's been compacted beyond all recognizable measure to the point where any object smaller than a human wouldn't even be able to be seen in its current state, assuming you could see the mass which makes up the black hole. Not to mention that when a black hole evaporates, it does so emitting radiation, like, a lot of it. Black holes aren't survivable.
