AZhZP-M is a big metal box weighing almost a tonne, with two cylindrical containers attached to it. One contains yeast dough, the other contains filling. The contents of both are pushed out through tubes so that the filling is encased by the dough; the machine cuts out equal lengths to form little oblong pies. They are placed on a special metal cradle that travels inside the box; there, the pies first rest for a while and then get dunked in a tub of hot oil. After 40 minutes, fresh PS1’s fall out of the box – one every four seconds on average.
Mr. Zadworny does not provide the name of the constructor of this ingenious invention. The details of its manufacture, which belonged to Soviet arms industry, have always been classified as a military secret. Or so, at least, claims the journalist, for whom the secrecy may just be a perfect excuse for not doing digging any deeper.
