The equipment costs about 1 1,000 yuan, the eggbeater 1 1,600-11,700 yuan, the electric oven 2 1 1,000 yuan, and a fermentation tank is needed. Materials are also sold for 300 yuan, but they are more expensive. All the equipment and electrical appliances need about 5000 yuan, which is enough. Learning this is a practical process. I learned it at school.
