Rotary spherical digester

Rotary spherical digester is rotary intermittent cooking and pulping equipment. It is spherical body, mainly composed of spherical body, machine seats, transmission devices and others parts. The sphere is made by welding or riveting steel plates. A loading hole is opened at the vertical centerline of the sphere for loading and feeding cooking medicine liquid. Steam for cooking and heating is introduced through the hollow shaft neck, and condensed water is discharged. The advantages of rotary spherical digester are that the raw materials inside the balls are fully mixed with the medicine, the quality of the pulp is relatively uniform, liquid ratio is low, medicine concentration is high, the cooking time can be shortened. This equipment is simple and investment is low.It is easy to manage and maintain.
