НАЖИМНАЯ ПЛИТА ДЛЯ ГИДРАВЛИЧЕСКОГО ПРЕССА

Номер: RU0000174761U1

Полезная модель относится к устройствам для прессования и тиснения листовых заготовок из различных материалов, таких как береста, кожа, картон и тому подобных, и касается конструктивных элементов гидравлических прессов, имеющих в своей конструкции один цилиндр поршневого типа со штоком, а именно к нажимным плитам для гидравлических прессов. Задачей предлагаемой полезной модели является создание технического решения, направленного на устранение разницы в давлении между центром и краями поверхности плиты в прессах с одним цилиндром поршневого типа и штоком. Технический результат - равномерное распределение давления нажимной плиты по всей площади поверхности заготовки, что ведет к повышению качества тиснения рисунка по всей поверхности заготовки.

The invention relates to cleaning and food processing aide applications whereby unique compositions of GRAS or food additives were developed to assess the effectiveness of cleaning procedures at various stages of the processes and to assess the delivery and adherence of food processing aides. Employing such solutions to clean and/or sanitize processing equipment provides a method to evaluate and enhance the effectiveness of procedures used to remove the respective fluorescent detergents, sanitizers or organic residues from equipment or niches and reduce contamination. Similar compositions were developed for assessing processing aide food surface coverage, contact time and adherence. In addition, unique compositions were invented that increase processing aide coverage and adherence. Quantification of the presence or absence of the fluorescent GRAS or food additive compositions produces results for validation, monitoring and/or verification of food safety intervention procedures/processes.
