6-Ton Direct Cooling Block Ice Machine

ICEMA-BMB60 is a mid-capacity industrial block ice plant delivering 6,000 kg of solid, transparent ice every 24 hours. It adopts a direct cooling aluminum plate evaporator with an optimized hot-gas defrost system, sharply reducing energy consumption per ton of ice. The machine is specifically designed for medium-sized fish landing sites, poultry processing, and concrete cooling, where reliable, high-hardness block ice is a daily necessity.

Product Overview

The BMB60 bridges the gap between modular stand-alone units and large central ice plants. Its evaporator is constructed from food-grade aluminum alloy plates with a special anti-corrosion treatment suitable for mild saline air. The refrigeration system employs a single screw compressor matched with a water-cooled shell-and-tube condenser, ensuring a stable condensing temperature even at 45°C ambient, making it suitable for tropical coastal regions.

Working Principle

Water is introduced into multiple vertically arranged ice-forming cells. Refrigerant flows in the jackets of these direct-expansion plates, extracting heat evenly and forming clear blocks free of air bubbles. At the end of the freeze cycle, a high-efficiency hot-gas defrosting circuit rapidly releases the blocks. The entire process—fill, freeze, harvest, and drain—is automated and adjustable via a digital cycle timer, minimizing operator intervention.

Advantages

The BMB60 features a dual-mode operating logic: "speed mode" for maximum output during peak demand, and "eco mode" that extends freeze time slightly to raise suction pressure, cutting kWh per ton. Siemens PLC with touchscreen provides error diagnostics and energy monitoring. The machine includes a built-in cold-water pre-cooling coil that uses defrost waste water to pre-chill incoming water, recovering up to 12% of energy. Standard power is 380V/50Hz/3P, It can also be customized according to the voltage standards of the customer's country.

Application Scenarios

Ocean fishing/port aquatic wholesale

Large block ice melts slowly, maintaining low temperatures in fishing holds or trading pools for 3~5 days, suitable for centralized ice use on ships or docks.

Food processing workshop environmental cooling

Place large ice blocks in the workshop during summer to continuously cool using high latent heat, with no wind chill, suitable for meat processing plants and dairy factories.

Concrete dam pouring temperature control

Crush large ice blocks into ice shavings during mixing; large blocks are easy to transport and store, with high direct cooling efficiency to meet the ice demand for engineering volumes.

Storage of vegetables/fruits pre-cooling

Block ice combined with cold fans is used for rapid pre-cooling in the field to prevent respiratory heat accumulation.

FAQ

Q: What ice size can the direct cooling block ice machine produce?

A: Customizable ice block sizes are available according to customer demands. Common specifications cover 5kg, 10kg and 20kg blocks. Hard and transparent ice fits seafood transport and cold storage application scenarios.

Q: Is the direct cooling block ice machine easy to install and maintain?

A: The machine adopts an integrated structure for convenient on-site installation. Few vulnerable spare parts are equipped. Regular cleaning of water system and condenser can effectively extend the unit’s service life.

Q: What water quality is required for the direct cooling block ice machine?

A: Clean tap water or well water can be used. Proper water filtration equipment is recommended to reduce impurities. Good water quality avoids scaling inside ice molds and guarantees long-term stable ice production efficiency.

Q: What are the core advantages of a direct cooling block ice machine compared with a traditional brine block ice machine?

A: 1. Energy-saving and power-efficient: No intermediate heat exchange loss, with power consumption of only 50-65 kWh per ton of ice, saving about 30% more electricity than brine machines;
2. Smaller footprint: No need to build a brine pool. The whole machine adopts a modular design, cutting the installation floor area by more than half and allowing flexible relocation;
3. Labor-saving: Fully automatic ice making, ice harvesting and ice moving. Only 1 to 2 workers are needed to manage the entire ice plant, with no manual ice fishing or mold pouring required;
4. Clean and eco-friendly: No brine corrosion or chemical medium pollution. The ice is edible, and the equipment produces no waste liquid discharge;
5. Easy maintenance: Simplified structure without cumbersome maintenance work such as brine pool pipeline rust prevention and brine proportioning adjustment.
