Specific embodiment:
[0022] Raw material processing: Take 10Kg of fresh jujube, and get 6.7 kilograms of raw jujube to be puffed after washing and de-nucleating.
[0023] Puffing: first raise the temperature in the puffing tank to 115℃, open the puffing tank, place the jujube raw materials to be puffed in the puffing tank, keep the temperature at 100℃, and increase the pressure in the puffing tank to 0.35MPa and keep it at 15 Minutes, then instantaneously reduce the pressure to a vacuum state. At this time, the equilibrium vacuum degree is above -0.075MPa. Start the vacuum system to reduce the vacuum degree to -0.098MPa; close the solenoid valve and reduce the temperature in the expansion tank to 80℃; Open the solenoid valve every 15 minutes, start the vacuum system, keep the vacuum at -0.098MPa, and hold for 10 minutes, close the solenoid valve. After this cycle 5 times, start the cooling system, the circulating cooling water temperature is 15℃, cooling for 55 minutes, Release t...
