Intelligent separation method for peanut kernel and red coat

An intelligent separation method of peanut kernel and red coat, using an intelligent separation device of peanut kernel and red coat, wherein the intelligent separation device comprises a gas explosion device, a stirring device, a drying device and a negative pressure adsorption device;

• the intelligent separation method, comprising:
• Feeding, by a conveying device, peanuts to be removed red coats into the gas explosion device, through an infiltration of supersaturated steam and rapid pressure relief method, the red coats of the peanuts are gas exploded under an action of pressure difference in the gas explosion device, to complete a preliminary separation of kernels and the red coats of the peanuts;
• feeding, by the stirring device, a primarily separated peanut kernels and peanut red coats of the peanuts into the drying device for drying;
• compressing outside air to raise temperature, transferring heat through hot air, and heating and drying the primarily separated peanut kernels and red coats of the peanuts in the drying device, to fully separate the red coats from the kernels;
• delivering, through a connection of the drying device to the negative pressure adsorption device, a fully separated peanut kernels and red coats of the peanuts into the negative pressure adsorption device;
• and
• collecting respectively the fully separated peanut kernels and red coats of the peanuts with different densities and qualities by a negative pressure adsorption mode, to obtain the kernels of the peanuts without the red coats;
• wherein, the negative pressure adsorption device comprises a negative pressure fan, a negative pressure pipeline, a negative pressure conveying device, a primary negative pressure collecting mechanism, a secondary negative pressure collecting mechanism, and a negative pressure storage unit;
• wherein,
• a primary collection of the red coats of the peanuts from the fully separated peanut kernels and red coats of the peanuts is carried out through the primary negative pressure collecting mechanism, a drying red coat collecting tank is connected with the primary negative pressure collecting mechanism, and an airbag on the primary negative pressure collecting mechanism is made to contract inwardly so that the negative pressure pipeline is closed due to a suction effect of the negative pressure fan;
• a secondary collection of the red coats of the peanuts is carried out through the secondary negative pressure collecting mechanism, and the collected red coats of the peanuts enter a material storage unit through the negative pressure pipeline.
