How is Donghuahuan decoction machine

The quality of Donghuahuan decoction machine is OK. I bought a 3+1 high pressure decoction machine (three decoction cylinders and a packaging machine). The main problem is not the damage of the electric board, circuit problems can be solved during the test drive. Instead, pay attention to the air leakage problem. Air leakage in the center shaft may be caused by uneven pressure around the screws. Careful adjustment can be solved. Around the gasket leakage is often due to careless operation.
