Product Types & Application Scenarios
Plate Shelf Freezer
Working Principle: Direct contact between food and metal plates, combined with cold air convection heat transfer to achieve dual efficient heat transfer of "contact + convection".
Core Features:
• Professional plate evaporator with uniform refrigerant evaporation and high freezing efficiency
• Stable and reliable hydraulic lifting system supporting long-term continuous operation
• Stainless steel liquid supply/return vapor pipelines with low temperature and corrosion resistance
Applicable Scenarios: Block/sheet food such as cut meat, aquatic products, poultry, prepared dishes, and some fruits and vegetables.
Plate Shelf Freezer
• Classification: Single-belt type (250~800kg/h), Double-belt type (500~1600kg/h)
• Core Features: Continuous production with high automation, suitable for large-scale assembly line operations.
• Applicable Scenarios: Products that do not require rapid stacking such as scallops, shrimp meat, fish fillets, fish sections, sushi fish, fried pastries, etc.
Plate Shelf Freezer
• Classification: Single spiral type (250~2500kg/h), Double spiral type (500~5000kg/h)
Core Features:
• Horizontal air supply with uniform cold air distribution and high heat exchange efficiency
• Small floor space and large production capacity, suitable for products requiring long freezing time and with high initial temperature
• Ensures consistent product freezing quality and slows down evaporator corrosion
Applicable Scenarios: Prepared dishes, aquatic products, poultry, ice cream, pastries, small packaged food, etc., especially suitable for long-process and large-yield requirements.
