Tunnel Freezer

Quick freezing refers to freezing the moisture inside food in a short period of time. Within 30 minutes, the core temperature of the food exceeds the ice crystal point, which is generally -2~-5°C. This is called quick freezing. Food that has been quick-frozen can maintain its taste to the greatest extent and can be stored and transported over long distances.

1. The conveyor mesh belt is made of 304 stainless steel spring wire, with a smooth surface and long service life.
2. The tunnel freezer machine uses imported frequency converters to achieve stepless speed regulation
3. The quick-freezing tunnel freezer machine can operate continuously, with high production efficiency and no need for manual transportation. The items are directly transported to the tunnel for quick freezing through the conveyor belt and then transferred directly to the next step of the process.
4. The refrigeration unit can automatically stop based on the volume of incoming and outgoing goods and the temperature inside the tunnel, which not only saves the power consumed due to frequent startup, but also improves the utilization rate and production efficiency of the equipment.
5. Quick freezing can maximize the freshness, original nutritional value and deliciousness of the product.

1. Within 30 minutes, the core temperature of the food drops from -1°C to -5°C, and the diameter of the ice crystal formed is <100um, which prevents the ice crystal from puncturing the cell wall of the food and ensures that the juice does not flow out.
2. Adopt a waterproof control box, button + knob operation control box, simple operation, saving manpower, text labeling, easy to learn and understand.
3. The freezing time is short. After passing through the quick-freezing environment of -35°C, the product can be quick-frozen in 15 to 30 minutes. The core temperature of the product after quick freezing is -18°C.
4. The quick tunnel freezer adopts 304 stainless steel mesh belt, which ensures clean material contact and smooth transportation.
5. The whole quick freezing machine is made of 304 stainless steel, which is beautiful and elegant overall. The thickness of the warehouse board is 120mm, and the four corners are made of thickened corner plates, which are formed in one step and have good thermal insulation.
6. The height of the feed port is adjustable, and the corresponding channel height can be adjusted for frozen products of different thicknesses.
