Abstract
A filling machine (10) for filling into containers (30), by volume, weight, or level, of products requiring maintenance of a specified temperature. The filling machine includes a product reservoir (14), a filling nozzle (16), a pump (22) and suitable tubes (26, 28) for controlling the flow of product from the reservoir to the nozzle. The above parts are disposed within a double walled enclosure (62). A conveyor (44) having an upper flight (44.2) which supports containers (30) to be filled via the filling nozzle enters and exits the enclosure. A heater (138) is located outside of the enclosure and is connected to the enclosure through an insulated air duct (130) so that forced hot air may be used for heating the enclosure. A heat sensor (158) is provided within the enclosure for controlling the flow of air into the enclosure and also for regulating the output of the heater. The enclosure is provided with two aligned doors (96, 98), and when these doors are opened a blow down cycle is initiated.
