The autoclave is in the form of a cylinder with an upper hatch and a lower hatch, while the autoclave ends with ellipsoidal end caps on both sides and there is a stirrer inside it, characterized in that the autoclave (1) is inclined from the ground plane by an angle of 3-8 ° in the direction of its outlet , the outer shirt (3) in the form of a membrane forming the outer space under pressure is mounted on the cylindrical section of the inner chamber (2) under pressure in an autoclave (1), while the shirt is divided into at least two pressure-separated hours ty (4). In the inner chamber (2) under pressure in the autoclave (1) is installed a shaft (7) of the paddle mixer, made to rotate clockwise and counterclockwise, and the mounting position of the mixer is a position with an offset relative to the axis of symmetry of the cylindrical section of the autoclave (1) the shift of the mounting position of the geometric axis of the shaft (7) of the mixer along the y-axis in a planar geometric system, and the size of the shift does not exceed 2/3 of the radial length of the cross section of the cylindrical section of the inner chamber (2) under pressure in oklava (1). Moreover, each of the blades (8) of the mixer has two casings (9), one for each of the opposite sides of the blade (8), and each casing (9) is shifted along the symmetry axis of the mixer relative to its blade (8) by the phase angle, equal to 90 °, and, moreover, the height of the casing (9) does not exceed 1/3 of the height of the blade (8) of the mixer.Автоклав в форме цилиндра с верхним люком и нижним люком, при этом автоклав заканчивается эллипсоидными концевыми крышками с обеих сторон и внутри него находится мешалка, отличающийся тем, что автоклав (1) наклонен относительно плоскости земли на угол 3-8° в направлении его выпускного отверстия, наружная рубашка (3) в форме мембраны, формирующей внешнее пространство под давлением, установлена на цилиндрической секции внутренней камеры (2) под давлением в автокл
