A conveyor (1) comprises two helical conveying tracks (2, 3) and a bridging track (4) which connects the two helical conveying tracks (2, 3) to each other such that products can be transported upwardly via one helical conveying track (2), then via the bridging track (4) to the other helical conveying track (3) and subsequently downwardly via the other helical conveying track (3). The conveyor (1) is provided with a driveable endless conveyor belt which follows at least one of the helical conveying tracks (2, 3), at least a part of the bridging track (4) and a return track (5), wherein the return track (5) at said one helical conveying track has a vertically oriented portion (5a) and a horizontally oriented portion (5b), which horizontally oriented portion (5b) is disposed below the bridging track (4) and extends beyond the vertically oriented portion (5a) with respect to the centre line of said one helical conveying track. |
