In fact, as long as these three steps are done well, the problem can be avoided. 1. Choosing copper-plated flat wire can increase the life of the equipment The quality of flat yarn mainly depends on the properties of raw materials and production processes.

Freshly roasted coffee beans will have a bean raising period, which is to release carbon dioxide and achieve the best flavor period of coffee. So how do we store coffee? To store coffee beans, we think of using  coffee bags   for the first time, but have you carefully observed the packaging bags of coffee beans? Ever notice a white or clear valve on the back or inside of the coffee bag? Or did you see it and didn't care? Don't think that this valve is dispensable when you see that the valve is small.

The one-way vent valve plays a vital role in helping your fresh coffee stay fresh longer. The one-way vent valve inside the coffee bean bag is a bag accessory that prevents backflow of air.
