12.Make thorough analysis of English and Russian texts to understand the idea of vacuum drying better.
1. Vacuum drying is ideal for the materials that would be damaged or changed if exposed to high temperatures. The vacuum removes moisture while preventing the oxidation or explosions. |
1. Вакуумная сушка является идеальным средством для веществ, которые могут быть повреждены или изменены при воздействии высоких температур. Вакуум удаляет влагу, не допуская окисления и взрывов. |
2. Vacuum drying saves time. Unlike atmospheric drying, drying under reduced pressure lowers the boiling point and provides a greater temperature difference between the heating medium and product. This results in faster drying and more efficient heat recovery. |
2. Вакуумная сушка экономит время. В отличие от атмосферной сушки сушка при пониженном давлении позволяет снизить температуру кипения и обеспечивает большую разницу температур теплоносителя и продуктов. Это приводит к ускорению высыхания и более эффективной рекуперации тепла. |
3. Vacuum drying saves money. Drying at lower temperatures reduces energy consumption. The dryers’ closed- system (or structural loop) design eliminates expenses for additional air-pollution control. |
3. Вакуумная сушка экономит деньги. Сушка при более низких температурах сокращает потребление энергии. Изолированная сушильная конструкция исключает затраты на дополнительный контроль над загрязнением воздуха. |
4. Vacuum drying protects workers. Since drying occurs in a closed system, hazardous materials and fumes are not released into the air. The potential for explosions is reduced because of the lower temperatures and the lack of dust and air in the dryer. |
4. Вакуумная сушка защищает рабочих. Поскольку сушка происходит в изолированной системе, опасные вещества и дым не выбрасываются в атмосферу. Вероятность взрывов снижается из-за более низких температур и отсутствия пыли в воздухе. |
