Spiral oil press, as an efficient oil press, is widely used in the processing of various oil crops. However, when some users use the newly purchased spiral oil press, they will encounter the situation that no cake can be produced, which may be confusing. Here are some possible reasons and solutions.

1. The equipment is not properly debugged.

The new machine may not have been fully debugged or calibrated when it leaves the factory. Spiral oil press needs to adjust proper pressure and cake discharge gap. If the pressure is too small or the gap is too large, the oil cake may not be discharged normally. It is recommended to read the equipment manual carefully and adjust the pressure and clearance according to the manufacturer’s suggestion to ensure that the equipment is in the best working condition.

2. The water content of raw materials is inappropriate.

The water content of oilseeds has a direct impact on the oil extraction effect. If the raw materials are too dry or wet, the oil press will not work normally or even produce cakes. Generally speaking, raw materials need to be properly pretreated, such as steaming or drying, to achieve a suitable water content (usually 8%-12%). Users are advised to check and treat the raw materials before use.

3. Improper installation of screw shaft or fittings.

In the assembly process of the new machine, there may be the problem that the screw shaft, press bar or press ring are not installed properly. If these parts are not installed correctly, it will affect the normal operation of the oil press, resulting in no cake. Users are advised to check the internal components of the equipment to ensure that all parts are installed in place and fastened.

4. Improper operation method.  

When using the spiral oil press for the first time, it may also cause problems if the operation is not skilled. For example, feeding too fast or too slow will affect the cake-discharging effect. It is suggested that users should gradually increase the feed rate according to the operation steps in the manual, and observe the operation of the equipment to find the best operation rhythm.

5. Foreign body blockage. 

If impurities or hard objects are mixed in the raw materials, the press chamber may be blocked, so that the cake can not be discharged normally. Before use, the raw materials should be cleaned to remove impurities. In addition, it is necessary to clean the equipment regularly to prevent foreign body residues from affecting normal work.

There may be many reasons why the newly purchased spiral oil press does not produce cakes, including equipment debugging problems, improper water content of raw materials, incorrect installation of parts, irregular operation methods and foreign body blockage. When users encounter such problems, they don’t have to panic. They can check and solve them one by one from the above aspects. If the problem still cannot be solved, it is recommended to contact the after-sales service of the manufacturer for professional technical support. Proper use and maintenance of equipment can not only improve work efficiency, but also prolong the service life of the machine.
