1. Poor quality of jujube: some jujube's skin is relatively hard, no matter what methods are difficult to beat off. It is recommended to choose better quality, thin and easy to break the skin of red dates to use the breakers.
2. Insufficient power of wall-breaking machine: the power of wall-breaking machine is different, some lower power machines may not be strong enough to break the skin of jujube. If you are using a lower power machine, you can try to adjust the time and operate several times to break the skin of red dates.
3. Insufficient operation time: the wall breaker needs a certain amount of time to break up hard ingredients. You can try to increase the operation time to give the wall breaker enough time to process the red dates.
4. Incorrect operation method: the correct operation method is also the key to ensure that the wall-breaker breaks the skin of red dates. You can try soaking the jujubes in moderate amount of water to soften the skin of the jujubes, and then put the soaked jujubes into the wall-breaker with moderate amount of water and stir.
If the above methods still can't break the skin of red dates, it may be that the quality of red dates is poor or the machine is not suitable for breaking red dates. You can try to use other tools such as blender or food processor to process the dates.
