The freezing production line is a set of equipment specially designed to efficiently process onions for freezing, ensuring onion quality and extending shelf life. It combines advanced technology and automation to simplify the production process and provide high-quality frozen onions.
The onion freezing processing machinery first removes the top and bottom of the onion to ensure a clean and uniform product for further processing.
The peeling machine uses mechanical or chemical methods to remove the outer skin of the onion, leaving a clean and smooth surface. The peeling stage is essential to remove the tough outer skin of the onion. It can avoid wasting onions in subsequent processing.
After peeling, the onion passes through the cleaning machine in the automated onion freezing processing machinery to remove any dirt, debris or residual peel. A high-pressure water jet or brush can be used to ensure thorough cleaning.
The cutting machine precisely cuts the onions into the desired size and shape, such as slices, cubes or rings. Different cutting options can be selected depending on the end use of the frozen onions. Uniform size is important for continuous freezing and subsequent use.
The dehydrator in the automated onion freezing processing machinery line removes excess water from the onions, helping to prevent ice crystals from forming during the freezing process and improving the overall quality of the frozen product.
The final stage is to quickly freeze the processed onions in a quick freezer. Quick freezing is essential to preserve the texture and flavor of the onions. The quick freezer uses low temperatures and rapid air circulation to quickly freeze the onions, maximizing their texture, flavor and nutritional value.
