摘要： A method of making a puffed, dehydrated food product comprises mixing a high amylopectin starch and selected food ingredients to form a dough; forming the dough into pieces; and exposing the dough pieces to microwave radiation at a pressure less than atmospheric to puff and dry the dough pieces, producing the puffed, dehydrated food product. The ingredients may include tomato paste, yogurt, fruit or fruit juice concentrate, fruit puree, vegetable puree, vegetable puree concentrate, coffee, and concentrated soup. The dough may be formed in the absence of starch hydrolysates. The method produces dehydrated food products which incorporate a variety of food ingredients in a matrix that has a puffed, crispy structure.

摘要： An apparatus and method for microwave vacuum-drying of organic materials such as food products. The dehydration apparatus (10) has a vacuum chamber (12) with a loading module (14) at one end and a discharge module (22) at the other. The vacuum chamber has access doors (80) spaced between the input end (16) and the discharge end (24) which provide operator and maintenance access. Microwave generators (86) are mounted on each access door and arranged to radiate through a microwave chamber and microwave-transparent window on the access door into the vacuum chamber. The waveguides on a respective access door are oriented to minimize microwave interference between the magnetrons on that door. A conveyor (60) in the vacuum chamber moves the organic material (96) on trays (18) through the vacuum chamber.
