Title: Biscuit or soft bake prodn in sterile conditions with air - tunnel and sealed packing
Inventor: HIRAKAWA KANEHIRO
IPC: A21D15/00
Filed: 1970-05-04
Abstract: Biscuit or soft bake is transferred under sterile conditions from the work room through a steriliser into an adjoining oven. The surface of the b ake wares are dried in a wind tunnel so that moisture is removed from these and from the crust areas only. This is followed by packing the bake in previously electronically sterilised plastics containers, sealing these subsequently, all in the sterilising chamber adjoining the work room. The doors of the chamber and room are interlocked so that only one can be open at any one time. Aroma, flavour, taste are preserved in bake wares completely free from outside contamination, and thus guarded against premature decay.
