How to Choose the Right Flake Ice Machine System for Concrete Cooling Projects

In concrete actual construction sites, temperature control is not just a technical detail, it directly affects the success or failure of the project. Once the temperature exceeds 30 ° C, the solidification rate of concrete will be too fast, heat will accumulate, and cracks and strength problems will occur. Therefore, applying a flake ice machine with a rake ice system for concrete mixing plant is one of the effective methods for controlling temperature. But equally important is to choose the appropriate configuration - an unsuitable system not only wastes money, but also slows down the construction period and affects the quality of the project.

Case Study: Flake Ice Machine & Rake Ice System — Shiziyang Passage Project

• The Shiziyang Passage is another major project in the Guangdong Hong Kong Macao Greater Bay Area. The double decker expressway has a total length of about 49.25 kilometers, a total investment of about 50.4 billion yuan, and 34 bridges along the entire route. It will be completed and opened to traffic in 2027.

• The project adopts the solution of a daily 30 ton flake ice machine, which is equipped with an intelligent ice storage and an automatic rake ice system. At the same time, the cold water system is integrated with the automatic ice storage, and the weighing of the ice supply system is achieved through a multi-stage screw ice feeding system.

• The goal of this project is to strictly control the temperature of concrete pouring within 28 ° C, to assist in the preparation of low-temperature, low shrinkage, and crack resistant concrete.

• During the month when the Icemedal refrigeration team entered the mixing plant site, they optimized and adjusted the system details according to the customer's on-site needs. The cooling system delivered during the project period meet the project requirements.

4 Key Factors for Selecting the Right Flake Ice Machine System

Calculate Daily Ice Consumption Before Anything Else

• One is to calculate the daily ice consumption. The first step in selecting is to accurately calculate the daily ice consumption. Taking the Shiziyang Passage project as an example, we have equipped a 30 ton flake ice machine according to peak demand, which helps to provide stable ice supply even in high temperature seasons. Usually, a margin of 15-20% is added to the estimated daily production for selection to cope with extreme working conditions.

  Match Equipment Capacity to Your Site Conditions

• The second is the selection of operating conditions. The rated production capacity of an ice machine is usually based on a temperature of 25 ° C and a water temperature of 20 ° C. When the ambient temperature exceeds 35 ° C, the ice making capacity will decrease by 15-25%; The higher water temperature, the higher power requirement for the ice machine. High humidity can also affect the efficiency of the condenser. Therefore, when choosing, it is need to require the supplier to provide the performance curve of the ice machine within the expected temperature and humidity range on site, so that the equipment can still meet the ice making needs under poor working conditions.

  Choose the Right Cooling Method: Air-Cooling vs. Water Cooling

• The third is to choose the correct cooling method. The choice of cooling method depends on the construction environment on site. The air-cooled system is easy to install and maintain, suitable for construction sites with mild climates but limited water sources. Water cooling systems are more suitable for projects with hot climates and high production capacity requirements, as their efficiency is stable and not affected by environmental temperature.

  Verify Core Component Quality — Compressor, Evaporator, Insulation

• The general principle is that in temperate regions, air cooling is preferred for daily production of less than 20 tons, while in large projects or tropical construction environments, water cooling is preferred.

• The fourth is to focus on the quality and reliability of core components. The quality of core components directly determines system stability. It is recommended to choose brands such as Bitzer and Hanbell for compressors, and choose 304 or 316 stainless steel for evaporator drums to ensure corrosion resistance. The insulation layer needs to use a minimum of 40 kilograms per cubic meter of high-density polyurethane. The control system recommends a PLC based touch screen interface to support remote monitoring functionality.

4 Common Mistakes to Avoid When Choosing a Flake Ice Machine for Concrete

Mistake 1: Selecting a System with Insufficient Ice Making Capacity

• Firstly, the selection of production capacity is too small. The high temperature in summer will reduce the ice making capacity, so it is need to leave a margin based on the calculated value.

  Mistake 2: Ignoring Water Quality — Hard Water Causes Rapid Scaling

• Secondly, water quality issues should be ignored. Hard water will quickly scale on the evaporator, and a water treatment system needs to be configured in advance.

  Mistake 3: Overlooking Ice Storage Insulation — Up to 15% Ice Loss Daily

• The third issue is the neglect of the insulation performance of the ice storage bin. Ice storage bins with insufficient insulation performance can cause 10-15% of the ice to melt every day in hot climates.

  Mistake 4: Choosing Based on Price Alone Instead of 10-Year Life-Cycle Cost

• Finally, we shouldn't only consider the price and not the total cost. We should calculate the comprehensive operating cost based on a 10-year span, rather than just focusing on one-time purchase prices.

  Choosing a Flake Ice Machine That Actually Works

  Choosing a suitable ice machine requires evaluating production capacity requirements and on-site environment, selecting appropriate cooling methods and core components, planning integration methods in advance, and calculating operating costs for more than 10 years.
