I am also a food factory. I told you responsibly not to buy second-hand equipment. If you are an expert, you can save about 20% money. If you are an amateur, it is as high as buying new equipment. Later, my machine was repaired, and accessories were hard to find. There are countless large and small factories producing equipment in China. Suggest buying a new one. At least there is room for machine failure after sale. Several colleagues, including me, bought some in Liangshan second-hand equipment market. If you don't discuss it, you can turn it over if you don't believe it. They sell the same quality as new ones, and they all save money. Actually, hehe. You have to look at a piece of equipment, material, thickness and model first, and then contact the price of a new online machine, knowing that it is full of holes.
