How Does One Shot Chocolate Machine Work?

The working principle of a one shot chocolate machine is centered on simultaneous injection of fillings and chocolates.

The percentages of both the chocolate and fillings are predetermined, during the injections, depending on the desired final product.

Consequently, the simultaneous injection results in the formation of filings coated with a chocolate jacket (shell).

Generally, the formation of praline or a chocolate-filled product involves three basic steps;

  • First, the nozzle casts the shell compounds as it moving upwards.
    Consequently, permiting the gradual formation of the shell
  • Next, the injection of the fillings occurs simultaneously.
  • Finally, the hell compounds entirely cover the fillings.
    In summary, for the automated one shot chocolate machine, you first need to fill the one shot chocolate machine with the required percentages of the chocolate and fillings.
    Upon powering on the machine, the parts simultaneously inject the two components. Eventually, you will have your filled chocolate product.
