Abstract: An intelligent separation device has gas explosion, stirring, drying and negative pressure adsorption devices. The gas explosion device receives conveyed peanut materials with red coats to be removed, and the materials are subjected to gas explosion, so that the peanut kernels and the peanut red coats are preliminarily separated. The stirring device shifts the preliminarily separated peanut kernels and peanut red coats into the drying device. The drying device compresses and heating external air, transfers heat through hot air, and heats and dries the preliminarily separated peanut kernels and peanut red coats, so that the peanut red coats and the peanut kernels are fully separated. The negative pressure adsorption device collects the fully separated peanut kernels and red coats with different densities and masses in a negative pressure adsorption mode.
