1. Equipment for manufacturing deep-frozen pellets of liquid or pasty products, comprising
a cryogenic tunnel; and
a conveyor belt capable of transporting the product to be processed in the equipment along a processing path that passes through various zones of the equipment, and the equipment implementing the following measures:
a. the equipment comprises an upstream zone situated upstream of a product inlet in the tunnel, the upstream zone comprising a device configured to meter and deposit the product to be processed into moulds formed in the structure of the conveyor belt;
b. the equipment comprises a pellet demoulding zone situated at the outlet of the tunnel or immediately downstream of the outlet of the tunnel; and
wherein the demoulding zone operates in a rotation zone of the conveyor, and the structure of the belt allows each pellet to be automatically demoulded by ejection, the ejection being effected by a given element of the structure of the conveyor belt on account of opposing forces being applied to the walls of the mould in the demoulding zone.
