Abstract

Liquid or solid products and particularly non-uniform granular products such as fruit and vegetables are weighed and dosed. A regular flow is obtained bya conveyor for a bucket weighing system. A product is stored in a hopper (30) whose outlet orifice (31) opens onto a conveyor (32) system on a vibrator (34). A wheel with blades (34) is driven by a motor and gearbox assembly (35) to provide a regular flow of the procuct. The speed is adjustable to provide the required flow into a bucket container (33) where the weight is determined. A feedback signal is used to control the motor speed. Shutters (39, 40) are operated by jacks (41, 42) to control supply to the weighing container and, when the required weight is obtained, the vibrator is switched off.
