How to Clean Your Freeze Dryer's Industrial Pump?
Step 1: Drain the Oil
Remove the drain screw with a hex key to completely drain the oil. Tilt the pump to ensure all oil is removed.
Step 2: Remove the Front Cover
Unscrew the four screws securing the front cover. Use a sturdy hex key for leverage, then carefully remove the cover.
Step 3: Clean the Interior
Wipe the inside with a dry towel, removing any gunk. Clean the cylinder and ensure no water remains. If rust is present, gently clean with a non-scratch sponge.
Step 4: Unblock the Oil Intake Hole
Check and unblock the oil intake hole at the bottom of the cylinder. Use a stick to ensure it's clear.
Step 5: Reassemble the Pump
Ensure the black seal is properly positioned, then replace the front cover and securely fasten the screws.
Regular cleaning extends the lifespan and performance of your pump. Follow these steps annually or when necessary to keep it in optimal condition.
When to change Oil?
To ensure optimal performance, oil changes should be made periodically:
-
Standard Pump: Filter or change the oil after 3-5 cycles or if it appears murky in the sight glass.
-
Industrial Pump: Change the oil every 30 batches or after 1000 hours of drying. Additionally, drain the oil in the demister after every batch and monitor the pump oil level.
Note: If the oil appears yellow but remains clear, it is still usable. Oil color can change due to pigments from the food, which does not affect its effectiveness. However, if water from the food mixes with the oil and causes it to look murky, then it is necessary to change/filter the oil.
