The invention discloses a freeze-dried red date-fruit-cereal biscuit and a
processing method thereof. The method comprises the following steps: adding fruits into a double-channel high-speed pulping
machine, and carrying out pulping, so as to obtain fine and uniform pulp; adding wheat germs and instant oatmeal into the pulp, and uniformly stirring, so as to obtain
slurry; introducing the
slurry into a vacuum tank, carrying out degassing, pouring the
slurry into a mold, horizontally scraping the slurry by virtue of a scraping plate, and introducing the slurry into a quick-freezing room; freezing at (-35)-(-45) for 2-4 hours in the quick-freezing room, and carrying out manual demolding; putting a biscuit into a freeze-
drying bin, cooling the material to -20 DEG C at a vacuum degree of lowerthan 10pa, standing for 30 minutes until the material is frozen, and introducing a
drying curve; when the weight of the material is constant, discharging the biscuit out of the freeze-
drying bin, andcarrying out demolding, so as to obtain the freeze-dried red date-fruit-cereal biscuit; and carrying out nitrogenization or
aluminum foil bag packaging. According to the
processing method, the nutrients in food materials are furthest preserved, and the freeze-dried red date-fruit-cereal biscuit has the
product characteristics of strong
fruit flavor, bright color and crispy taste and can be taken as
meal replacement food.
