A vacuum steam blancher using a full-automatic conveyor belt includes a blanching chamber, a pressure casing, a second vacuum pipe; and an automatic control system. The automatic control system is configured to control a steam generation system, a vacuum system, a drainage system and a material conveyor. Steam is introduced to continuously blanch materials. The vacuum steam blancher has a simple structure and reasonable design, and is easily integrated with a production line. Compared to the existing vacuum pulsed blancher that is intermittent and semi-automatic, the vacuum steam blancher of the present application realizes continuous production to meet the needs of the industrialized production.

The present invention discloses a method for designing a refiner plate with three-stage radial curved bars, comprising following steps of: designing a circle arc for 1stage radial curved bars; designing a circle arc for the 2stage radial curved bars; designing a circle arc for 3stage radial curved bars; and designing a center angle for the refiner plate according to the size of the refiner plate and the manufacture requirements, to complete the design of the refiner plate. In the present invention, by the establishment of equations for the circle arcs and angles of inclination of the curved bars, it is ensured that the width of the bars will not change in the radial direction, and both the flexibility in designing a curved refiner plate and the uniformity of crushing are improved. This design method provides a theory basis and also instructions for designing multi-stage radial curved bars.

The present invention discloses a method for designing a refiner plate with equidistant curved bars, comprising following steps of: designing a central bar are of center curved bar and defining the bar angle for the equidistant curved bar; designing circle arcs for curved bars on two sides of center curved bar of equidistant curved bar segment; when the whole refining segment is full of circle arcs, trimming lines of outer circle arcs of the refining segment to complete the design of equidistant circle arcs on the two sides; and if required, dividing the bars into zones. In the present invention, by the definition of the bar angle for the curved bars and the parametric design of the equidistant curved bars by using circle are equations, it is ensured that the flexibility in designing an equidistant curved bar refiner plate is improved.
