6) pouring, cooling and forming: the pouring temperature is controlled to be 32 +/-2 ℃, the current of the conveying motor is controlled to be 5 +/-1A, the temperature of the cooling tunnel is 8 +/-3 ℃, and the cooling time is 25 min.

2. The method for efficiently and automatically producing 72% black chocolate with high quality according to claim 1, wherein the discharge state of the two-roller machine is judged according to the hardness of the black chocolate in the stirring and mixing stage.

Technical Field

The invention relates to the field of dark chocolate, in particular to a method for efficiently and automatically producing 72% of dark chocolate with high quality.

Background

Chocolate is prepared from cocoa product (cocoa mass, cocoa butter, and cocoa powder), granulated sugar, dairy product, spice, and surfactant by mixing, grinding, refining, adjusting temperature, casting, cooling, and shaping; wherein, in the grinding and refining processes, the main raw materials comprise cocoa powder, cocoa butter, milk powder, sucrose, phospholipid and the like. The raw materials are powdery and need to be ground into slurry. The existing grinding production process has low grinding automation, high required labor cost and low efficiency, and can grind the raw materials to reach the required fineness by long-time operation so that the raw materials have fine and smooth mouthfeel.

Therefore, a process technology capable of efficiently producing 72% dark chocolate with excellent quality is yet to be provided.
