Contact Freezer
Quick Freezing System
The contact freezer utilizes contact-based rapid freezing technology. This method relies on the significantly higher thermal conductivity of metal compared to air to transfer cold efficiently. Food items are placed horizontally or vertically on one side of a plate evaporator (metal freezing plate), allowing the metal to quickly conduct cold to the food, achieving rapid freezing.
Also known as a plate freezer, it is ideal for freezing tray-packed, block-shaped foods that are resistant to pressure or easy to mold, such as portioned meats, poultry, and by-products. It provides a reliable and efficient solution for preserving the quality of these products during freezing.
- Efficient thermal conductivity with rapid freezing speed, short freezing times, and high-quality frozen products with minimal moisture loss
- Its design eliminates the need for fans inside the equipment, resulting in significantly reduced energy consumption and enhanced operational efficiency.
- Compact design with a small footprint, saving valuable space
- Delivered as a fully assembled unit, reducing construction costs for customers
This contact freezer is a double-sided, contact-based freezing system designed for batch operations. Food items are placed between multiple layers of freezing plates, which are hydraulically operated. During operation, the plates separate to allow for loading and unloading, and then compress to freeze the food efficiently. This design ensures uniform freezing while maximizing productivity for batch processing applications.
Features
- Designed without internal fans, ensuring low energy consumption and high operational efficiency
- Equipped with an insulated storage chamber and delivered as a fully assembled unit, eliminating on-site construction costs

This contact freezer combines the MPF series plate freezer with its matching refrigeration compressor and condenser unit, all mounted on a shared base to create a fully integrated freezing system with a self-contained cooling source. Depending on the type of condenser, it is available in two configurations: air-cooled plate freezers and water-cooled plate freezers. This design ensures convenience and flexibility for various freezing applications and requirements.
Features
- Integrated design with a compact structure for easy installation and operation
- The air-cooled plate freezer requires only a power connection, while the water-cooled plate freezer needs both power and water connections to start operation, ensuring quick and hassle-free setup.
