The invention discloses a chocolate impregnation biscuit
processing method. The
processing method comprises the steps of a, chocolate preparation, b,
grinding and melting, c, regrinding, d, refining, e,
filtration, f, stirring, g, vacuum impregnation, h, cooling and i, packaging. According to the step of vacuum impregnation, stirred thick liquid is pumped into a vacuum tank at first, biscuits are placed into the vacuum tank, the weight ratio of the thick liquid to the biscuits is 1:0.8, standing is kept for 6 min to 8 min, then the vacuum tank is sealed to be vacuumized, the pressure inside the vacuum tank is controlled to range from 0.5 MPa to 0.6 MPa, the state is kept for 5 min to 6 min, then the vacuum tank is opened, the temperature inside the vacuum tank is always kept to range from 45 DEG C to 50 DEG C, and finally redundant chocolate on the surfaces of the impregnated biscuits are thrown off through a centrifugal
machine which works for 4 min to 5 min, wherein the centrifugal
machine rotates 450 turns to 500 turns per minute. The chocolate impregnation biscuits have the advantages that the taste is good, consumers can taste the
chocolate flavor with every bite when eating the biscuits, the taste of the chocolate impregnation biscuits is more unique, and the brand new chocolate impregnation biscuits are made.
