A potting machine fills automatic pots with substrate (soil). They are mainly used for growing pot plants. Empty pots are placed in the pot holders. This can be done manually or by means of a pot dispenser. The potholders are mounted on a wheel or a chain. The pot holders go under a pot filler. This filler ensures a uniform filling of the pot and the excess soil is removed. Subsequently, the soil is pressed by a pressure unit. The potting machine can optionally be equipped automatic pot tranfer, which places the filled pots automatically on a conveyor belt.
