Process for dehydrating frozen food particles
摘要:
The invention relates to a process for dehydration of food products, particularly fish and meat, by freezing the product to be dehydrated, subdividing it in frozen condition to particles and drying it by contacting it at substantially atmospheric pressure with a gaseous drying agent, by distributing the frozen particles on a movable or fixed carrier means, through which the drying agent is passed to form a firm porous mat and gradually increasing the velocity, and optionally the temperature, of the drying agent through said porous mat to continue the drying thereof after which the mat is torn up to a dehydrated powder.
