Abstract

The details of a device, being basically common for making high quality primarily mechanical, but also semi-mechanical and chemical pulps from almost all kinds of cellulosic raw materials such as wood, waste papers and non-wood plants - and with low capital and operating costs - are disclosed.
These raw materials, mainly due to the sloped configuration of the platform, butt against the retaining bars to maintain a relatively constant distance from the shower headers which are located behind these bars. These headers, through the shower jets, apply oscillating, fan-shaped, overlapping, hot water sprays under pressure, with or without chemicals, to the surface of the cellulosic material being defibered - to make pulp. The dislodged fibres i.e. the pulp passes through the floor-openings, to be collected and processed by the normal industry methods. As an example, to make a mechanical pulp from debarked logs, the pressurized, oscillating, hot jet water sprays, with or without chemicals, surround the wood fibres, soften the lignin, and dislodge the horizontally oriented wood fibres gently and in relatively less-damaged conditions. By using relatively low jet hot water pressure at a constant distance to a large amount of raw material at the same time, this basic-for-all-pulping device, with its low capital and operating costs, is an improvement on the existing art to manufacture uniform quality, strong pulps.
