摘要:
A device (1) for mixing liquids of different viscosity or composition within at least one container (2) is proposed. Each container (2) comprises an inner chamber (3) with an enclosing wall (8) and a bottom (10); an external encasement (6); an interspace (9); and a transfer opening (11) located at a top side of the inner chamber (3). A mixing body (12) located in the inner chamber (3) comprises magnetizable material (13) or a permanent magnet (13') and is spaced apart from the wall (8). The mixing device (1) comprises a coupling body (16) that is movable in the interspace (9) in direction of a longitudinal axis (4) and alongside the wall (8). The wall (8) and the external encasement (6) are transparent to magnetic fields. The coupling body (16) is in magnetic working connection with the at least one mixing body (12). At least one acting permanent magnet (19) or acting magnetizable material (19') located outside the external encasement (6) is in magnetic working connection with the coupling body (16). Moving the at least one acting permanent magnet (19) or acting magnetizable material (19') parallel to the longitudinal axis (4) of the inner chamber (3) simultaneously induces movement of the coupling body (16) inside the interspace (9) and moving the at least one mixing body (12) in the inner chamber (3), thereby mixing of liquids present in the inner chamber (3) of the container (2) is performed.

摘要:
Компоненты теста перемешивают в тестомесильном аппарате (2). Полученное тесто делят на порции, каждую из которых сбивают с получением аэрированного теста. Перемешивание и сбивание проводят различными устройствами. Сбивание проводят под давлением не менее 0,3МПа с последующим снижением давления до атмосферного с регулируемой скоростью порядка 0,02-0,2 МПа/с. Снижение давления до атмосферного производят либо до, либо после вывода сбивающего устройства 6 из теста. Процесс сбивания проводят в хлебопекарных формах (1), или в промежуточных стаканах (16), с последующей перегрузкой в формы (1). Перегрузку производят либо в формы (1) находящиеся под атмосферным давлением, после снижения давления в промежуточных стаканах 16 до атмосферного, либо в формы (1), находящиеся под повышенным давлением, а снижение давления до атмосферного производят после перегрузки. Изобретение позволяет упростить и повысить точность деления теста, повысить качество сбивного теста, снизить энергоемкость и увеличить производительность производства.
