Abstract

A continuous operation apparatus for fermenting dough products disposed on carriers which are conveyed stepwise through a fermenting chamber by vertical and horizontal conveyors. In order to obtain maximum space utilization and product density in the fermenting chamber with vibration-free and shock-fee transfer of the carriers, a vertical transport system is provided in which several vertical pairs of columns are employed to support the carriers at successive vertically spaced levels or stages and to stepwise transport the carriers vertically. One of the columns of each pair is rotatable while the other of the columns is rotatable and vertically displaceable. The pairs of columns are provided at each stage with horizontal projections for the support of the carriers. The carriers are transported stepwise by the vertically displaceable columns and successively transferred onto the rotatable columns.
