Abstract

The invention relates to a freeze dryer and a method for inducing controlled nucleation in liquid products. The freeze dryer for inducing nucleation in water based products (44) to be freeze-dried comprises a product chamber (12) adapted for housing a vapor gas and the products (44), a condensation chamber (16) connected to the product chamber (12) over an isolation valve (36) in a gas conductive manner, said condensation chamber (16) being provided with a gas pump (18), a gas transfer line (20) connecting the product chamber (12) with at least one cooling device (22) being adapted to generate ice-crystals when said vapor gas is withdrawn from the product chamber through the cooling device (22) in a first gas flow direction (streaked arrow), the freeze dryer being adapted to—after the generation of the ice crystals in the cooling device (22)—convey a flushing gas through the gas transfer line (20) in a second gas flow direction (white arrow) going reverse to said first gas flow direction in order to thereby entrain the ice-crystals from the cooling device (22) into the product chamber (12) to induce nucleation of the products (44) therein. The freeze dryer is particular in that the gas transfer line (20), which comprises the cooling device (22), is separated from the gas pump (18) at least by the condensation chamber (16), the condensation chamber (16) providing a gas passage for the withdrawn vapor gas during the withdrawal in the first gas flow direction, and a gas passage and/or gas storage for the flushing gas during the conveying in the second gas flow direction.
