Choke device and an assembly to supply a granular or powder product provided with the choke device, in particular for an automatic beverage vending machine

A feed assembly for feeding a granular or powder product for an automatic beverage vending machine, the assembly comprising a feed duct for feeding said granular or powder product to guide the product along a feed path and towards a product discharge container, the duct having a discharge section delimiting a product outlet opening towards the container, the discharge section comprising at least one intermediate portion made of elastically deformable material and a terminal portion delimiting said outlet opening;

• the assembly furthermore comprising a choke device configured to receive said discharge section and comprising:
• an attachment frame designed to be connected to a fixed support;
• a choke member coupled to said attachment frame and having a support surface for said discharge section;
• and motorized means for moving said choke member with respect to said attachment frame between a support position, in which it maintains the discharge section in a product feed condition, and an overturned position, in which said support surface extends in a substantially vertical position to elastically deform and at least partially choke said intermediate portion and said discharge section upstream of said outlet opening in the product feed direction along said feed path, and maintains said outlet opening facing upwards;
• when the choke member is arranged in its overturned position, said terminal portion being overturned backwards with respect to the feed position and said outlet opening facing upwards.
