Abstract: Изобретение относится к устройствам для измельчения материалов и может быть использовано в комбикормовой, пищевой промышленности, сельском хозяйстве, в частности, для измельчения зерна. Дисковая мельница включает ведущий и пассивный диски, установленные эксцентрично относительно друг друга, мелющая поверхность дисков выполнена с симметрично расположенными относительно друг друга пазами. Мелющая поверхность дисков состоит из внутреннего, среднего и внешнего поясов с рифлями. Средний и внешний пояса выполнены в одной плоскости, параллельной диаметральным осям диска, а внутренний пояс - в плоскости под углом γ к ним, с постоянной шириной основания Н на длине паза, соответствующей минимальному радиусу среднего пояса, одинакового для пассивного и ведущего дисков, на которой дно пазов пассивного и ведущего дисков выполнено параллельным диаметральным осям дисков. Сечения пазов в плоскости, перпендикулярной их длине, имеют форму прямоугольника и постоянную ширину основания Н. Глубина пазов пассивного и ведущего дисков на длине от начала среднего пояса до конца паза изменяется от h 0  до 0, сечения пазов в плоскости, перпендикулярной их длине, имеют форму прямоугольной трапеции, передняя по направлению вращения сторона которой паза ведущего диска и задняя - пассивного диска выполнены радиальными и равны высоте трапеции, нижнее основание равно ширине паза Н. Задняя по направлению вращения сторона прямоугольной трапеции паза ведущего диска и передняя - пассивного диска наклонены к основанию под углом χ, равным χ=180-α, при этом угол α определяется из выражения 
     
       
     
     где ω - угловая скорость вращения пассивного диска, рад/с; Н - ширина паза, м; g - ускорение свободного падения, м/с 2 ; f - коэффициент трения скольжения. Глубина паза пассивного диска на длине внутреннего пояса уменьшается с уменьшением длины паза от R 1  до R 0  по зависимости h 0 -(R 1 -R)·tgγ, где R 1  - минимальный радиус среднего пояса; R 0  - минимальный радиус внутреннего пояса; R - текущий радиус (R 0 <R<R 1 ), м; γ - угол наклона внутреннего пояса к среднему. Изобретение позволяет повысить производительность за счет появляющейся возможности более быстрой эвакуации продукта из пазов пассивного диска. 2 ил.

Abstract: FIELD: chemistry; biochemistry. 
     SUBSTANCE: invention pertains to biotechnology. Disclosed is a method of extracting L-lysine from culture fluid. Biomass-free culture fluid is acidified to pH 1.9-2.3. Lysine is sorbed from the obtained solution on a sulphocationite strongly cross-linked with polystyrene to saturation or close to saturation state. The cationite is washed from said solution with water at temperature 70-85°C and consumption of desalinated water is equal to 1.1-1.3 times the volume of the ionite layer. Elution is carried out with 5% ammonia solution. The lysine-containing fraction is collected when pH 6-7 is attained. A sulphur-containing antioxidant is added to the lysine-containing fraction in amount of 0.28-0.43%. Primary vacuum-evaporation of the fraction is carried out with concentration of the solution 2.3-2.8 times. The obtained concentrate is neutralised with hydrochloric acid. Said concentrate is adsorptionally clarified on a macroporous weakly basic anionite of the condensation type. Secondary vacuum evaporation is carried out. Lysine monochlorohydrate is then crystallised. The crystals are separated from the mother solution and dried at temperature 85-90°C.
