Close the bypass valve and fill the blanching furnace with steam. When the steam pressure drops to 0.38 mpa, the equipment can start heating automatically.
3. Adjust the valve to ensure that the steam pressure of the filling furnace is in the range of 0.04-0.07 mpa. Pump can automatically replenish water to ensure the water level between the upper limit and the lower limit.
