Sewage discharging for filter
Ambient temperature around the machine should be maintained at 0-40.
In places with night temperature may lower than 0, residual fluid inside the air compressor and air filter shall be removed after shutdown of machine. With the water discharging function, the air compressor and oil-mist separator will automatically discharge water when it reaches to certain height, while it would be difficult to discharge water as the water discharging port will be frozen when the temperature is below 0. Thus, it is required to discharge water manually.
If operate the machine with the compressed air temperature lower than 0, air supplied for the air filter and oil mist separator shall be dried by the air drier as the moist air would frozen the internal filter element, which hampers the air flow and cause damage to the filter element.

In-service inspection
During the operation, inspect the signal indication (including the work instruction, alarm indication) and spray valve operation; inspect the pressure of air compressor and its sound, with water discharging at least one time every 8h.

Maintenance after operation
Clean the feeder (especially the coagulation inside the feeder hopper), interior of the machine, material-receiving hopper and ash removing brush by air gun.
Note: it is forbidden, in cleaning the material-receiving hopper with air gun, to blow the nozzle directly with air gun, which will cause damage to the nozzle valve.

Regular maintenance and inspection
1Monthly: check the filter element and the cleanliness of the ash removing brush.
2Quarterly: check the fluorescent lamp.
3Half a year; check or replace lubrication oil for the compressor at least one time.
Warning: in order to prevent static electricity and ensure the personal safety, the host machine and its attached equipment shall be in good ground connection. Electric cabinet opened by professional only. It is forbidden to open the rear case cover of the cabinet in operation as it is a fully enclosed automatic cycle air cooling system.

Colour sorters or color sorters (sometimes called optical sorters, digital sorters, or electronic colour sorters) are machines that are used on the production lines in bulk food processing and other industries. They separate items by their colours, detecting the colours of things that pass before them, and using mechanical or pneumatic ejection devices to divert items whose colours do not fall within the acceptable range or which are desired to form a separate group from the rest.

How does a color sorter work? The raw material enters the machine from the top hopper/storage hopper. Through the vibration of the vibrator device, the raw material slides down the channel accelerate down into the observation zone in the sorting cabinet and pass between the sensor and the background plate.
