A shutter panel includes a frame, and a louver coupled to the frame for rotation about a longitudinal axis across a given angular travel range of the louver. The shutter panel also includes a louver closure assembly operable to automatically rotate the louver into a closed position when the louver is moved into a specific angular range of louver positions within its angular travel range. For instance, in an exemplary implementation, the louver closure assembly is configured to linear translation into rotational movement of the louver.

The present disclosure relates to methods of enriching root powder products, for example beetroot powder. In particular, the methods relates to increasing the nitrate content and/or reducing the sugar content of the root powder product. The disclosure also relates to root powder products with increased with at least 3% nitrate.

In one aspect, a shutter assembly includes a shutter frame and a plurality of louvers supported by the frame. The shutter assembly also includes a louver drive assembly and a. motor positioned within the frame. The motor is configured to rotationally drive a drive shaft extending within the frame. Additionally, the shutter assembly includes a clutch assembly rotationally coupled between the drive shaft and the louver drive assembly. The clutch assembly is configured to disengage or decouple the drive shaft from the louver drive assembly when a torque transmitted through the clutch assembly exceeds a given torque threshold.

A louvre shutter comprising louvres 20 rotatably mounted in a frame on louvre axles, and a louvre drive system that, in summary, comprises a rack and pinion gear system including an externally operable rack assembly and a set of pinion gears 28 mounted to the louvre axles. The rack is externally operable rack and is reciprocably mounted in the drive system housing 42, 48. The pinion gears 28 mounted to the louvre axles are engaged with the rack such that reciprocation of the rack rotates the louvre 20 relative to the frame.

A door arrangement has a door frame, a door leaf, door hinges and a magnetic closure device, wherein the door hinges are fastened on a hinge side of the door leaf and join the door leaf swivelably with the door frame. The door frame has a step for stopping the door leaf in the closed position, the step having a stop arm overlapping the door leaf in the closed position and a lateral arm. The closure device is formed from a magnet arrangement on the door frame as well as a magnetic material on a rim of the door leaf. The magnet arrangement is disposed on the lateral arm in such a way that a gap remains between the magnet arrangement and the magnetic material disposed on the rim of the door leaf.
