Kreuzmayr Equipment Maintenance Checklist: Start Your Season Right!
September is here and the season is beginning to change! This also means apple harvest is just around the corner and we want to arm you with everything you need to get your apple juice processing equipment ready for the upcoming pressing. Starting up your equipment and ensuring everything is operating smoothly is key to starting off your harvest on the right foot. We’ve broken down what to look for in this Kreuzmayr Equipment Maintenance Guide below!
It is very important to make sure these bearings are properly greased. This means you should just be able to see the grease on the seal, not dripping out! The photo on the left has no grease while the photo on the right has the proper amount. If the grease that is coming out of your bearings is brown, the bearings may be rusty and need replacing. Not to worry, our support department can send this to you!
Inspect all the seals to make sure they are all intact and none are broken. They should be tightly touching the shaft to prevent any water from entering.
On the images you can see the inside seal of the right seal is worn down. This will allow water to enter the bearing and cause it to rust
Check the oil level on the gearbox of the elevator.
You can do that by removing the plug seen here on top of the gearbox. Add oil as needed.
Kuebler Paraliq 460 oil or equivalent is what we recommend.
Check out your elevator belt to make sure it has the right tension. To test this, lift up the belt and see if you can lift it to the top edge of the stainless steel. If it is the correct tension, it will be flush with the top edge without having to strain the elevator too much. See our support technician, Rodger, demonstrating this on the right!
Ever looked inside your grinder? Now is the time! The grinder has teeth with four sharp edges that you can rotate to maximize their usage. If they are rounded, as shown in the photo on the left, you can rotate them to the sharp edges, pictured on the right.
Switches & Sensors:
Try out all the switches and sensors to verify each one functions as it’s supposed to.
Yep, bearings again! Take note to make sure these are all properly greased, as pictured above in the elevator section. Additionally, make certain these bearings are not seized. To determine this, release all the belt pressure and manually turn all the rollers and they should move easily. Please note that the drive roller cannot be manually turned.
This bearing seen on the right is greased but contains rust in the grease which can contribute to seizing and excessive wear. If this is what your bearing look like, please call!
Press Juice Level Control:
This sensor is in charge of the automatic function of the juice pump as the liquid level of the juice increases. To do this, it uses air pressure to gauge and should activate the pump. The pump will then turn on and take the fresh juice to the holding container once the pan is full. It will shut off the press if the juice pan becomes over full.
Both of these functions can be tested by slowly lowering it into a pail of water. Dip the sensor in the pail slowly and observe the activation of the functions. Once at fill level, it will activate the pump and once it reaches overflow level it will halt the press. As well, it is a good idea to check the push-in fitting for this airline and ensure it is intact.
Keeping the press clean is a must! That’s why checking your brush roll cleaner on your press is an important part of this checklist. The bristles should all be straight, not bent, and all of the same length. The photo on the left shows what sparse bristles look like while the photo on the right is what they should look like. If your brush cleaner is looking like the one on the left, give us a call!
Take a look at this hose for tears and rips and validate that it has no blockages. The pivot points should also be looked at to make certain the bushings are in working order.
If you hear squeaking of the bushings or even worse, the arm is banging, it is time to replace the bushings.
Please contact us to order a spare set.
Automatic Belt Centering:
A crucial part of this checklist! The automatic belt centering does exactly just that, it makes sure the belt is in alignment to reduce strain and ensure maximum durability. To check if this is working properly, push on the belt paddle, photo shown on the left. Once this paddle is pushed, the piston, pictured on the right, should move the belt roller back and forth. In the right picture, you can see a worn gliding block. If that is seized or difficult to move, please call our support line at 250-351-9306!
Take a look at your gearbox to see the levels of oil through the sight glass. If it does not have a sight glass, simply remove the filling level screw and fill with oil until the oil is pouring out of the screw. Please note this is not the venting screw with a hole in it.
Kuebler Paraliq 460 oil or equivalent is what we recommend.
Emergency Stop Functionality:
Safety first! The belt press has four different emergency stop functions; the pull cord, cover sensor, pressure sensor and lastly the stop button. To test the pull cord, when you pull it the belt press should stop and the button should be pressed in. To reset, pull out the button and a green band at the bottom should be showing.
For the press cover sensor, ensure the belt will not start unless the cover is closed. With the pressure sensor, ensure this is working as well. Lastly, check to see if the emergency stop button fully stops the belt press. If any of these functions are not working, contact us directly at 1-351-9306.
It is important to ensure that the belt is not broken or torn. Make sure to check the seams of the belt. Some common things to look for are missing staples and peeled-up tape. You can cut the peeled-up tape with an exacto knife so that it does not caught during operating. Please give us a call for further information.
Rubberized Drive Roller:
Make sure to check the rubberized drive roller for wear and tear! The most common areas for wear are on both ends of the roller. If it is not in good working condition, call us for further instructions.
Just like above, look at the Destoner bearings and see if these are greased. Check that the motor side bearing, found under the motor cover, is working and not seized. This will also need sufficient greasing. You should be able to turn the rotors manually.
Take a look at these circuits and make sure they have the correct pressure and is able to hold that pressure overnight. If there is any air inside the system, you will need to flush it out.
Check all temperature sensors as well as the sensors on the pumps to verify they are reading correctly. Temperature sensors can be checked against an NSF calibrated thermometer. This should be done on a regular base during the operating season as well.
Investigate the boiler and ensure there isn’t any soot. Check to see that the burner fires and burns correctly. Check with your local burner rep to make sure the burn rate, air amount as well as exhaust measurements are correct. This ensures your pasteurizer burns efficiently and transfers heat to the heat exchanger effectively.
If all else fails and you need help with this step, who ya gonna call? Our support team!
Great Work, You're Finished!
Congratulations! You’ve completed the Kreuzmayr Equipment Maintenance Guide. This proactive approach to starting your season makes sure your apple juice processing equipment is ready for smooth operations. Regular maintenance is crucial to getting high yields and maximum durability through intense usage so you can keep doing what you do best!
Overwhelmed with it all?
If the above is sounding like a foreign language or you don’t have time to do all the maintenance, we can arrange a service visit at your location. Alternatively, you can ship it to our location for an overhaul. Please make sure you give us enough time to do the work. Ideally, the best time to schedule this is right after your pressing season to get your Kreuzmayr equipment in the best shape possible for the upcoming harvest!
