The invention provides a nut and dried fruit bar and a production process thereof. Compared with the prior art, the nut and dried fruit bar organically combines smashed biscuits, smashed nuts and dried fruits, and the prepared product is rich in nutrient; meanwhile, in the production process, by means of multiple times of water spraying operation by means of a spraying kettle, material surfaces are wetted, the materials can not be added at a time, and it is avoided that the materials are wetted by water too much and the product taste is affected; meanwhile, the adhesiveness of the raw materials is higher, and it is avoided that crumbs are generated to affect the selling appearance and yield of the product. Due to the baking temperature and the time, the product taste is ensured, and nutrients are not lost; then, fire spraying is conducted through a fire spraying gun, the product is fired for 2-3 seconds, the combination of the materials is closer, crumbs can not be easily produced, obvious sugar particles or powder particles on surfaces can be fired and melted, and the product has a better selling appearance.
