Valmet Enzymatic Starch Cooking ZE is a patented starch cooking process for board and paper makers which is designed for starch quality and stability and where process environmental sustainability is crucial. It consists of two separate preassembled units for dissolving and cooking of surface size starch and binder starch. With the built-in heat recovery and new circulation system, it decreases energy consumption and decreases load and cost for water treatment. The new starch circulation system enables starch powder savings of several tonnes per month and decreases the load and cost for water treatment.

Modular process for white water treatment

Valmet Ultrafiltration W process is a solution for paper and board mills to produce colloidal, bacteria-free, ultrapure water from the white water. The main targets are reducing fresh water consumption, improving paper machine runnability and production efficiency, and controlling the energy balance. When a paper machine's showers and process stay clean for a longer time, the need for shutdowns is reduced. This has a significant effect on paper machine efficiency and product quality. A higher process temperature increases drainage, allowing increased paper machine speed and results in increased productivity. Water recycling allows the recovery of heat and raw materials. Valmet Ultrafiltration W helps to enhance the positive effects of recycling.

Ensure clean starch circulation in size press operations

The Valmet Starch Cleaning Booster is an innovative solution designed to prevent the accumulation of dirt particles in size press starch circulation systems. This system is essential for maintaining the quality and efficiency of the sizing process. The starch cleaning booster offers several key benefits such as enhanced screening, space efficient design and automatic backflow washing. The system can be installed while the machine is running, minimizing downtime, and ensuring continuous operation. The starch cleaning booster operates without disturbing the existing sizing process, guaranteeing no pressure variations at the sizer. The typical scope includes a centrifugal pump, OptiScreen RF pressure screens, precise instrumentation, and expert engineering support.

APP Jingui PM2 - Seamless cooperation creates maximum synergy

APP Jingui BM2 is a complete large-scale high-speed production line for coated white cardboard, delivered by Valmet. APP Jingui BM2 has been a success from the moment it started up. It took only three hours to achieve a smooth start-up in the uncoated section – from the stock entering the headbox to leaving the pre-calender. Watch the video to learn more about the cooperation between Valmet and APP, that resulted in a success from the start.
