The invention discloses a deep-grain walnut kernel quick-heating quick-cooling dry-method
coating removing process which comprises the following steps: (1) a quick-heating stage: dry walnut kernels enter a feeding hopper of a quick-heating shoveling plate
machine, are uniformly mixed with high-temperature
quartz sand under the operation of a shoveling plate, and are conveyed to a discharging table; (2) a rapid cooling stage: the rapidly heated walnut kernels enter a rapid cooling shoveling
machine, are uniformly mixed with low-temperature
quartz sand under the operation of a shoveling plate, and are conveyed to a discharging table; (3) kernel and coat separation: the walnut kernels enter a feeding tray and enter an
air pump brush machine, and the walnut kernels and the coat are preliminarily separated under the action of pulse
airflow and a
brush; and (4) kernel and coat sorting: finally conveying the walnut kernels by a
conveyor belt, and enabling kernel coat residues to enter a residue
discharge channel through a fan. After the technological process is adopted, the peeling efficiency of the walnut kernels in the current market can be improved, no
chemical agent needs to be added, the production cost is saved, meanwhile, the fragrance and
nutrition of the walnuts are not damaged, the industrial economy is further improved, and the
bottleneck of rapid development of the walnut kernel industry is solved.
