Why choose frozen pre cooling?
Pre cooling preservation is a key step in extending the shelf life of fresh shrimp and maintaining the freshness and tenderness of the meat. Whether it is short-term storage or long-distance cold chain transportation, the choice of fresh ice pre cooling equipment directly affects the operating costs, product quality, and customer satisfaction of enterprises. Fresh food processing enterprises need to make targeted choices between tube ice machines and flake ice machines based on actual scene requirements.
Comparison of core product parameters
1. Flake Ice machine parameters
• Production capacity: 1000-30000kg/day
Ice flakes thickness: 2-3mm, flat and thin sheet shape
Energy consumption: 0.3-0.5kW · h/kg ice
• Floor area: Approximately 3m ² for small and medium-sized equipment, and 5m ² or more for large equipment
Applicable temperature: -5 ℃ to 0 ℃ (refrigeration system temperature)
• Core components: evaporator, ice making blade, ice scraping roller
2. Parameters of ice tube machine
Production capacity: 1000-50000kg/day
Ice tube diameter: Φ 8- Φ 12mm, hollow tube shaped
Energy consumption: 0.5-0.7 kW · h/kg ice
• Floor area: Approximately 4m ² for small and medium-sized equipment, and 8m ² or more for large equipment
Applicable temperature: -10 ℃ to -15 ℃
Core components: rotating ice making tray, compressor, circulating water pump
Functional application scenarios
Scenario 1: On site processing+short-term storage
• Recommended choice: Ice Flake Machine
Applicable reasons:
• Quick freshness locking: The contact area of sliced ice is large, which can quickly reduce the surface temperature of shrimp to -1 ℃, preventing the meat from oxidizing and turning black.
• Easy to operate: Ice flakes are fragile and have strong fluidity. They can be directly covered with shrimp or mixed into packaging without the need for complex packaging.
• Storage period: Suitable for sales completed within 72 hours, the ice can be quickly cleaned through the drainage system after melting.
Scenario 2: Long distance cold chain transportation
• Recommended choice: tube ice machine
Applicable reasons:
• Melting resistance: The melting time of tube ice is 2-3 times longer than that of sheet ice, and it is suitable for transportation for more than 8 hours (such as inter provincial or sea freight).
• Uniform cooling: The hollow structure inside the ice tube can slowly release cooling capacity, avoiding ice crystal damage to the shrimp body due to sudden temperature drops.
• Space utilization: Hollow tube ice can fill the gaps in the box, reducing damage to shrimp bodies caused by vibration during transportation.
Product core advantages and differentiation comparison
Advantages of Flake Ice Machine
1. Rapid cooling: Flat thin sheets have a large surface area, and the cooling rate is 40% faster than tube ice.
2. Low maintenance cost: The structure is simple, there are no rotating parts, the failure rate is low, and the annual maintenance cost is about 60% of the tube ice machine.
3. Flexible adjustment: switchable ice thickness (2mm/3mm) to meet the pre cooling needs of different products.
Advantages of ice tube machine
1. Long term preservation: A single shipment can maintain a low temperature environment for up to 12 hours (usually only 6 hours for sliced ice).
2. Health and safety: The entire process of ice production is sealed, and the bacterial adhesion rate is less than 0.5%.
3. Energy saving mode: Some models are equipped with intelligent temperature control, which can save 20% of electricity costs by making ice during low electricity periods at night.
Process technology details (key to ensuring stable operation)
Core technology of ice flake machine
• Dynamic ice making technology: By rotating the ice scraper to control the thickness of the ice layer, the error range is ≤ 0.1mm, ensuring even ice flakes.
• Energy saving cycle system: The refrigerant is environmentally friendly, with an energy efficiency ratio increased by 15%, in line with international carbon emission standards.
Core technology of ice pipe machine
• Circular ice tray: Hollow tube ice forming process, the surface of the ice tube is smooth and not easy to breed microorganisms.
The core logic of choosing a tube ice or flake ice machine is: short-term freshness depends on speed, and long-distance transportation depends on endurance. Fresh food enterprises need to consider multidimensional factors such as processing scale, cold chain path, and budget, and prioritize on-site inspections of similar enterprise cases.
