Frozen pineapple cubes are a convenient, nutritious, and versatile semi-finished fruit product. The main equipment for their large-scale processing is a iqf tunnel freezer.

This frozen pineapple cubes machine employs advanced low-temperature rapid freezing technology, quickly lowering the center temperature of pineapple chunks to below -18℃ in a short time, allowing them to pass through the maximum ice crystal formation zone in an extremely short period. Rapid freezing effectively locks in the pineapple’s moisture and nutrients, reduces cell damage, and maintains its excellent taste and appearance.

IQF Tunnel Freezer Machine Working Principle:

Tunnel freezer machines generate low-temperature cold air (typically between -35°C and -45°C) through a refrigeration system. High-efficiency fans then circulate this cold air at high speed inside the tunnel, ensuring thorough heat exchange with the pineapple cubes on the conveyor belt. This forced convection cooling method rapidly removes heat from the pineapple cubes, allowing them to freeze in a short time.

Frozen Pineapple Cubes Machine Features:

Fast Freezing Speed: The high-efficiency evaporator and large-volume circulation system design allow materials to pass quickly through the ice crystal formation zone, ensuring product quality.

Uniform Freezing: The multi-layer air duct design ensures uniform temperature distribution inside the tunnel, avoiding incomplete freezing in certain areas.

Hygiene and Safety: The iqf tunnel freezer machine is made of food-grade stainless steel, with a reasonable structure, easy cleaning, and meets food processing hygiene standards.

Other Pineapple Processing Equipment:

To improve efficiency and product consistency, the production of frozen pineapple cubes typically includes other equipment to automate the entire process from raw material processing to finished product freezing.

① Pineapple Peeling Machine

An automatic peeling machine quickly removes the pineapple peel and eyes, significantly improving efficiency and reducing labor costs.

② Dicing Machine

An adjustable blade assembly cuts the pineapple into uniform cubes (e.g., 10mm, 15mm, 20mm, etc.).

③ Packaging Machine

After freezing, an automatic weighing and packaging machine can be installed as needed to package the frozen pineapple cubes into different sizes (e.g., 500g, 1kg, etc.) for final cold storage.
