Utrustningsbeskrivning
The screw digester is a critical equipment in the chemi-mechanical pulping process, primarily used for conveying, compressing, and preliminary cooking of fibrous raw materials such as wood chips. Inside its screw conveyor, fibrous materials are progressively compressed while soaking in precisely dosed cooking chemicals and steam. This controlled environment softens lignin, weakens fiber bonds, and preps materials for Raffinering-boosts massakvaliteten och effektiviteten .

Arbetsprincip

Inside the screw digester, a rotating screw shaft moves material along the axial direction. The spiral design doesn't just push material forward-it creates a rolling, mixing action as it travels. This constant tumbling ensures thorough contact with steam and chemical liquid medicine, assuring fast, even heating and reaction throughout the digester.

Användningsanvändning

Raw materials (e.g. wood chips, bamboo chips, and wheat straw) can be precisely controlled during the cooking process by setting the temperature and rotational speed of the equipment, adjusting the residence time and reaction temperature of the materials in the cooking tubes, to ensure materials cooking exactly as required for different products.

Utrustningsegenskaper

Skruvkokaren har enkel struktur, effektiv kontinuerlig produktion, enhetlig uppvärmning, litet fotavtryck, exakt processkontroll, inget tryck och ingen fara, vilket gör den lämplig för kontinuerlig produktion av nuvarande kemi-mekanisk massa .
