Kindly send me an email with the details and I will get back to you. First, we need to make the ice cram base. These large-scale plants usually have multiple mix tanks whose volumes correspond to the plant’s hourly capacity (determined by the capacity of the pasteurizer) to ensure that the process is continuous. The actual freezing takes place at between -15°C to -20°C for 3 – 5 minutes. The mix in the mixing tank is heated to 70°C and held for 30 minutes. This article will articulate the fundamentals of ice cream-making process. If frozen butter/cream is used, then cut them into small pieces and add into the mix in good time to allow total melting before the pasteurization temperatures are applied.
