Abstract: Способ быстрого приготовления комплекса блюд заключается в том, что в герметичный блок секций (далее комплект блюд), состоящий из нескольких секций, отделенных друг от друга перегородками, помещены подготовленные сухие концентрированные пищевые продукты быстрого приготовления, из которых можно изготовить первые, вторые и третьи блюда. Горячую жидкость заливают в секции со вторым и третьим блюдами. Так как секции для первого и второго блюд соединены между собой и выполнены как сообщающиеся сосуды, то после обводнения и насыщения влагой второго блюда вся избыточная жидкость из секции второго блюда перетекает в секцию первого блюда. Днища в секциях второго и первого блюд могут быть выполнены в одном уровне или дно секции первого блюда может быть ниже дна секции второго блюда. При приготовлении комплекса блюд могут быть использованы комплекты блюд двух вариантов: комплект блюд, который при приготовлении блюд и его потреблении располагается только в горизонтальной плоскости, или комплект блюд, который при приготовлении комплекса блюд первоначально при заливе горячей жидкости и в течение некоторой временной выдержки расположен в горизонтальной плоскости, а затем из горизонтального положения его переводят в вертикальное положение, при этом также дают некоторую временную выдержку и вновь возвращают в исходное горизонтальное положение. Для приема пищи независимо от варианта используемых комплектов блюд предварительно вскрывают крышки над секциями каждого из блюд, начиная с секции первого блюда и т.д. Это позволяет повысить удобство приготовления и потребления комплекта блюд в индивидуальных условиях, в сфере общественного питания, а также обеспечить возможность организации приема пищи в некомфортных условиях. 7 ил.
