This utility model discloses an aluminum
alloy single-freezing tray, including an upper frame structure and a lower single-freezing tray. The upper frame structure has an isosceles trapezoidal cross-section, which is inverted, resulting in an upper opening larger than the lower opening. The lower single-freezing tray has a rectangular cross-section with an open top. The upper frame structure and the lower single-freezing tray are integrally formed, and the connection between them is set as a limiting edge. During freezing or transportation, the aluminum
alloy single-freezing tray can be stacked to save space without hindering the freezing and appearance of the frozen products. It also enables rapid freezing, reduces ice
crystal formation, avoids
cell structure damage, ensures uniform
cold air circulation, and improves freezing efficiency.
