Speed Control Not Functioning Correctly

This procedure will guide you through the steps to troubleshoot the speed control not functioning on your Goodnature SX-280 press. The SX-280 press is designed to squeeze product mash at a slow and steady pace. Pressing too fast causes the bags to fail and causes the mash to raise up and out of the bag. It is almost always better to press slowly. The flow control valve meters how much fluid is allowed to pass through it, hence changing the pressing speed. On the SX-280 there are separate flow controls for the forward and reverse directions. The pressing speed difference from a fully open flow control valve to a half open flow control valve is minimal to an observer. This is why it may appear as though you have no speed control. But from half way open to the fully closed position on the flow control valve, there is very noticeable speed difference. This is the zone you will want to operate in. Troubleshooting the Flow Control Valves (Speed Controls) You will want to begin with the press cylinders fully extended and place the directional switch into the neutral position. Turn the flow control knob for reverse clockwise until it stops. This is the closed position. Place directional switch into the reverse direction, the platen should not move. If the platen moves the flow control valve has failed and needs to be replaced. If the platen does not move, place the directional switch back into the neutral position. Turn the flow control valve counter clockwise ½ of a revolution and place the directional switch into the reverse position. If the platen is moving very slowly, your flow control valve is functioning normally. For additional technical support needs, contact our technical support team.

Press Will Not Turn On

This guide will walk you through the reasons why your Goodnature SX-280 press is not turning on. There are a few reasons that your SX-280 press will not turn on. For the purpose of this article, it is assumed that the SX-280 press is plugged into an operational receptacle that has been verified by qualified personnel. The electrical enclosure for SX-280 has two separate controls for powering on the SX-280 press. The first component is the On/Off disconnect switch, and the second being the red E-stop button. Either of these components could likely be the issue if you are having issues getting power to the motor. Troubleshooting the On/Off disconnect switch When the disconnect switch is placed turned to the “ON” position, the operator should feel resistance while turning the handle as well as hear the switch when it actuates. If neither of these two indicators are observed and the motor will not turn on, contact qualified personnel to repair or replace the disconnect switch. Troubleshooting the E-stop The red E-stop button is a push/pull operator. When the e-stop is pulled out, it is considered to be in the “ON” position. When it is pushed in it is “OFF”. Anytime that you switch between the two states (on/off) you should hear the contacts engage and disengage with a an audible “click”. If this is not observed and the motor will not turn on, contact qualified personnel to replace the e-stop. Turning on the press In order for the motor of your SX-280 to turn “ON”, both of these controls must be in the “ON” position. If both of these controls are in the “ON” position and the motor will not start, have qualified personnel power up the electrical assembly with the electrical box open. Turn the disconnect switch “ON”, followed by the E-stop. What does the display on the VFD read? This error message may indicate the issue. Write down the error message and contact Goodnature.

Press Will Not Dump

This procedure will guide you through the steps to troubleshoot why your press will not lift and dump on your Goodnature SX-280. There are a few reasons that your SX-280 press area will not lift up and dump. For the purpose of this article, it is assumed that the SX-280 press is plugged in to an operational receptacle that has been verified by qualified personnel and the motor is operational. Troubleshooting and Repairing the Issue: With the directional switch in the neutral position turn on the motor. Place the two dump stops into their closed positions. The black levers should be horizontal. Press and hold the “Raise 1” button. While holding the button observe the pressure gauge, it should read approximately 2300 psi. If the gauge does not read 2300 psi, adjust pressure relief valve. If little to no pressure is achievable the pressure relief valve needs to be cleaned or replaced. The pressure relief valve is located in the manifold block just behind the stacking directional valves. Now that the pressure has been properly set/verified and the dump stops are open, does the press area raise? If the press area does not raise, have qualified personnel inspect the solenoid on the directional valve. The directional valve for raising the press area is the upper valve mounted to the manifold block. It is recommended that two replacement solenoids be kept in stock to prevent excessive downtime. For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

Press Will Not Move

This procedure will guide you through the steps to troubleshoot why the press will not move on your Goodnature SX-280. There are a few reasons that your SX-280 platen will not move in one direction or both directions. For the purpose of this article, it is assumed that the SX-280 press is plugged in to an operational receptacle that has been verified by qualified personnel and the motor is operational. Take the following steps to troubleshoot the issue: Troubleshooting and Repairing With the directional switch in the neutral position turn on the motor. Place the two dump stops into their closed positions. Black levers should be horizontal. Press and hold the “Raise 1” button. While holding the button observe the pressure gauge, it should read approximately 2300 psi. If the gauge does not read 2300 psi, adjust pressure relief valve. If little to no pressure is achievable the pressure relief valve needs to be cleaned or replaced. The pressure relief valve is located in the manifold block just behind the stacking directional valves. Now that the system hydraulic pressure has been verified/adjusted, place the directional switch into the forward/reverse position and be certain to open the flow control valves for both directions completely. Does the platen move? If the platen moves, allow it travel to the closed position and build up pressure. In the forward position the gauge should read 1800 psi, in the reverse position the gauge should read 2200 psi. If either direction reads differently than these values, the stacking relief valve needs adjusting. If the platen does not move, have qualified personnel inspect the solenoid on the directional valve. The directional valve for forward and reverse is the lower valve mounted to the manifold block. It is recommended that two replacement solenoids be kept in stock to avoid excessive downtime. For additional technical support needs, contact our technical support team.

Low Hydraulic Fluid Level

This procedure will guide you through the steps to troubleshoot low hydraulic fluid levels on your Goodnature SX-280. The hydraulic power unit consumes very little hydraulic fluid. The most common reason behind a low hydraulic fluid condition is a leak at some point in the system. Leaks can usually be identified by a slick on the floor below where the leak is occurring. Any leak not attended to in a timely manner can result in a low fluid condition. How Do You Know if You Are Low on Fluid? The first sign will be a gurgling sound resonating from the power unit. This gurgling will occur as the platen is moving from completely closed to open. Another sign will be sluggish response from the cylinders when the platen begins to move from the completely open position. If either of these conditions are observed you will need to check your fluid level. How to Check the Oil Level The reservoir of the X-6 has a zinc coated breather cap installed in it. This cap should only be hand tight and is where you will check the fluid level. Important: Fluid levels should only be checked with the SX-280 in the completely retracted position. After ensuring that the cylinders are retracted, shut off the power unit and remove the black cap. Using a dip stick check to see if the fluid is within 1” of the top of the reservoir (you can use a rolled up paper towel as a dip stick). If the level is low, add fluid until the level is within 1” of the top of the reservoir. Only use an ISO32 Food Grade Hydraulic Fluid.

How Many People Does it Take to Operate?

How to correctly operate your Goodnature SX-280 with the proper personnel. The Goodnature SX-280 is designed to be used by a single operator. In an ideal production environment, there will be other people involved with preparing the produce and removing spent pomace, but the press itself should be used by one person only. For more detailed information on operating your SX-280, refer to the SX-280 Owner's Manual. To order new parts and press bags, visit the SX-280 parts page.

Hydraulic Fluid Leak

This procedure will guide you through the steps to troubleshoot a hydraulic fluid leak on your Goodnature SX-280. Mitigating or precluding hydraulic fluid leaks can be handled by frequently checking and tightening all of the fittings and hoses on your SX-280 press. It is recommended to perform this maintenance once a week. However, you may still experience a leak at a fitting, or a defective hose, which can lead to press operation failure. If you are experiencing a fluid leak at a fitting or hose-end, Follow these steps for troubleshooting and repair: Turn off your SX-280 press. Tighten the fittings on the SX-280 which appear to be leaking. Clean the area off of all fluid and turn your SX-280 back on. Watch closely the hose-end or fitting suspected of leaking. If there is no apparent accumulation of fluid, place the press under pressure by moving the platen to either direction. When the platen closes and proper pressure is achieved(1800 psi for forward and 2200 psi for reverse), check the suspected area again to see if fluid is accumulating. If fluid begins to accumulate at the fitting joint, or appears to be coming from the hose-end, you may be experiencing a defective O-ring in the fitting or a loose or defective hose-end, in which case replacing the fitting and hose will be necessary. Goodnature recommends having a set of extra hoses on hand to guarantee that you do not experience the loss of production time. However, if this is not possible, you may contact Goodnature and have hoses or fittings shipped out to you. (It may also be possible that O-rings for fittings be found at your local Hydraulic parts store). For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

Can You Press With Just a Few Layers Full?

Utilizing your SX-280 layer capacity correctly will produce the best product outcome. We advise against only pressing with only a few layers full. Any presses with scissor assemblies which open each bag layer evenly and simultaneously such as the SX-280 and SX-200 must have the same amount of pomace in each bag to prevent immediate damage to scissor assemblies. If you need to short fill the press, do so by filling all bags evenly at or above 50% full. Filling below 50% will put uneven stress on the frame and moving platen which can potentially cause damage. For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

Rack Ties Breaking

Experiencing rack ties breaking on your Goodnature SX-280? It might be time for a replacement. Rack ties are considered a consumable so from time to time, replacement should be expected. Proper installation of the rack tie is crucial to rack tie longevity. When installing the rack ties, you will want to snug the rack tie at the top of the rack and leave the rack tie loose at the bottom. See picture below of properly installed rack ties. Goodnature recommends stocking 20 rack ties at all times to ensure no loss of production time. For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

Bag Loops Are Splitting or Breaking

Experiencing the bag loops splitting or breaking on your Goodnature SX-280? It might be time for a replacement. Bag loops are considered a consumable part so time to time replacement should be expected. When you notice a small slit (generally during cleaning or bag installation) the bag loop should be replaced immediately. Goodnature recommends stocking 25 bag loops at all times to ensure no loss of production time. Proper installation of bag loops and proper press operation will ensure bag loop longevity. See below for a picture of properly installed bag loops. For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

How Many Pressings Can I Do in an Hour?

The SX-280 was meticulously designed to ramp up production for commercial juice and cider production. Desired yields and throughput need to be accounted for when determining an amount of cycles achievable in an hour. Between grinding and pressing your product, 8-10 press cycles per hour should be expected. Up to 12 cycles per hour on easy to process products. For more detailed information on operating your SX-280, refer to the SX-280 Owner's Manual. To order new parts and press bags, visit the SX-280 parts page.

Can I Press Different Fruits and Vegetables at the Same Time?

Yes. The bag and grinding disc you will use will depend on which of the products being ground and pressed is the dominant one. Example: If apple is the dominant product in the mix, the #2636 bag and 5/8” or 7/8” screen will be used to press and grind your product. Note: if grinding and pressing a soft product with a hard product, slow down your grinder from 60 hz to about 40 hz so the soft product doesn’t liquefy in the process. For more detailed information on operating your SX-280, refer to the SX-280 Owner's Manual. To order new parts and press bags, visit the SX-280 parts page.

What Is the Fastest Press Cycle, in Minutes?

Understanding the press cycle speeds on your SX-280 press is key to obtaining an excellent product. A slow and steady press cycle is always recommended. For most cold press applications an overall press cycle should not be much faster than 5 minutes. Difficult to press products could take as long as 10 minutes. For more detailed information on operating your SX-280, refer to the SX-280 Owner's Manual. To order new parts and press bags, visit the SX-280 parts page.

Cracked Press Rack

Experiencing a cracked press rack on your Goodnature SX-280? It might be time for a replacement. Press racks are considered a consumable so time to time replacement should be expected. When you notice a hairline crack, generally during cleaning, the rack should be replaced immediately. Continued operation with a cracked rack will eventually cause damage to the press bags. Goodnature recommends stocking 8 press racks at all times to ensure no loss of production time. Proper installation of replacement racks is critical to rack longevity. When installing replacement racks be certain to snug the rack ties at the top of the press area and leave the rack ties at the bottom loose. Over tightening of the bottom rack ties will cause too much stress on the both the tie and the rack, leading to premature failure. This will be most noticeable in the closed position. For additional technical support needs, contact our technical support team. To order new parts and press bags, visit the SX-280 parts page.

Washing and Sanitizing Press Bags

These procedures will guide you through the steps to washing and sanitizing your press bags for your Goodnature cold-press juicer. Applies to Goodnature juice presses that use reusable cloth press bags. PURPOSE: To prevent foodborne illness by ensuring that all food contact surfaces are properly cleaned and sanitized. Warning: Always follow regulations stated by local health services. When to wash, rinse, and sanitize press bags: After each use Any time contamination occurs or is suspected Every four (4) hours of constant use for all food contact surfaces Wash, rinse, and sanitize press bags using the following procedure: Wash bag with water and brush to remove all surface food particles Wash surface with detergent solution Rinse surface with clean water Sanitize surface using a sanitizing solution mixed at a concentration specified on the manufacturer’s label. Keep bags soaking in sanitizing solution overnight to assist with keeping bags white. Place wet items in a manner to allow air drying before use. We do not recommend machine drying as this can result in shrinking and will lessen the lifespan of the press bags. Pro Tip: If not using that often, store dry bags in a sealed container to avoid exposure to dust or build up. Then do a quick wash before use. Do not store damp bags in a sealed container – it will make it easier for bacteria to grow. If a 3-compartment sink is used, setup and use the sink in the following manner: In the first compartment, wash with a clean detergent solution at or above 110° F or at the temperature specified by the detergent manufacturer. In the second compartment, rinse with clean water. In the third compartment, sanitize with a sanitizing solution mixed at a concentration and contact time specified on the manufacturer’s label or by immersing in hot water at or above 171° F for 30 seconds. Test the chemical sanitizer concentration by using an appropriate test kit. If a dish machine is used: Check with the dish machine manufacturer to verify that the information on the data plate is correct. Refer to the information on the data plate for determining wash, rinse, and sanitizing (final) rinse temperatures; sanitizing solution concentrations; and water pressures, if applicable. Follow manufacturer’s instructions for use. Ensure that food contact surfaces reach a surface temperature of 165° F or above if using hot water to sanitize.
