Cheese surface dusting machine - has fluidised bed of powdered salt in chamber blown over cheeses on conveyor by air nozzles

摘要

The machine dusts the surfaces of cheeses with salt and operates continuously. It comprises a chamber, divided horizontally by a porous membrane (4). This is covered with a layer (F) of powdered salt, replenished by air suction (30) from a side container (27). Air is blown through the membrane by a fan (5) in the lower part (2) of the chamber, the air being filtered (14) and warmed (7). A row of nozzles projecting into the salt form a salt curtain, the cheeses (18) being placed on wire trays (17) and passed through on a conveyor (15). An air curtain (23, 24) is each end and the salt is dispersed by deflectors (21, 22).
