Summarize several common misunderstandings of hanging-ear coffee and attach tips for correctly brewing hanging-ear bags.

In fact, there are not many things to buy, that is, the inner ear bag and the aluminum foil outer bag, as well as the sealing machine to seal them. I bought 100 inside and outside bags each.

As for the sealing machine, I studied it, and some people said I wanted more than three thousand, but I asked the merchant who sold the sealing machine. In fact, as long as I could seal the 5MM wide sealing machine, I could use it. I thought it might just be used by myself and my colleagues, so I could buy a cheap one. I bought the following one, only 1100, but to be on the safe side, I still took the bag to try it, and it can be used!

I estimated the cost. The inner bag is 2.4 yuan and the outer bag is 1.3 yuan. If you put in 9 grams of bean flour, it is 0.3 yuan per gram, which costs 2.7 yuan, so excluding wages and equipment amortization fees, the cost of making an earbag is 7.4 yuan. However, if you buy these things, it may be more than freight.

As for the future use, I would like to do a few for colleagues to try out, if the response is good, I think we can also sell online and say … It would be nice to have the opportunity to develop production skills.

In the first production photo, the first one on the right-hand side is the 7th baked beans. I baked these two batches with confidence, and once I drank it, I felt that the caramelization was very successful, so I packed a few bags while fresh. The second one behind is a small funnel, which is very important. In the middle of it, I found that the mouth of the inner bag was very small. I must have a funnel to put the powder in it.
