The logs are transported into the warehouse by the conveyor, sliced by the slicer, then entered the chip warehouse, screened by the vibrating screen, and screened out the uniform chips, and then entered the "water washing" process.

wash

The water washing system cleans the wood chips cut into specifications, removes impurities such as mud stones and sand contained in the wood chips, and ensures that the clean wood chips are transported to the next process.

steaming

Vertical digester is an important equipment in production line. In this equipment, wood chips are cooked and softened under saturated steam with pressure of 6-8 bar and temperature of 150- 160℃. The residence time of wood chips in the digester is 65438 0-3 minutes. Vertical digester is a kind of pressure vessel, which can ensure the removal of harmful substances that may exist in logs.

Thermal pulping

Thermal grinding is a very critical production process. In this equipment, the cooked wood chips are separated into fibers in a high-speed rotating millstone. The grinding chamber pressure of the thermal mill is 8-9bar, the temperature is 140- 150℃, the total installed capacity is 7000kW, and the rotating speed is 1500rpm. Thermal grinding system is a high temperature and high pressure system, which can also fumigate sawdust and fiber.

dry

The drying system is the largest air conveying system in the production line, which uses high-temperature flue gas as heating medium to dry the fiber to the specified dry humidity. Harmful substances are further removed in this system.

The dried fibers are screened, and the qualified fibers are respectively measured by the conveyor and the ground scale, and then sent to the paving machine to pave a flat slab.

Hot pressing

Continuous hot press is the most critical equipment in the production line. The equipment can quickly solidify the adhesive in the slab and press the slab into shape through the precise coordination of temperature, pressure and production speed.

cultivate

Stack the formed blank in a special area according to the number of photos, let it adjust itself and fully release the physical stress. This process is about two days, which is called health preservation. After curing, the properties of the plate will be more stable and not easy to deform.

sand papering

Use sander to process the surface of fiberboard and correct the thickness. Remove the pre-curing layer on the surface of the plate to improve the utilization rate of the plate surface.

cut

According to the specifications required by customers, the size of the board is standardized.

Enter the warehouse

Finished product packaging, numbering and warehousing. A well-ventilated and constant-temperature warehouse can ensure the stability of product quality.
