CBFI industrial water-cooled chiller
The booming development of the food industry and the demand for precision in cold chain logistics and processing technology have put forward extremely high requirements for the stability, energy efficiency ratio, and temperature control accuracy of refrigeration equipment. CBFI industrial water-cooled chillers have become the preferred solution for refrigeration systems in the food industry due to their high efficiency, energy saving, precise temperature control, and modular design.
The core requirements of the food industry for refrigeration systems
Each stage of food processing and storage has strict requirements for temperature control:
1. Cold chain logistics: From raw material transportation to terminal distribution, specific temperature zones such as -18 ℃ to 4 ℃ must be maintained throughout the entire process to prevent microbial growth or food spoilage;
2. Processing technology: Accurate temperature control (within ± 0.5 ℃) is required for meat freezing, dairy product fermentation, and pre cooling of fruits and vegetables;
3. Energy consumption management: Food companies usually operate continuously for 24 hours, and high energy consuming equipment will directly drive up operating costs;
4. Space adaptability: Cold storage or workshops need to balance the flexibility of space layout between refrigeration equipment and production lines.
CBFI water-cooled chillers use twin-screw compression technology, environmentally friendly refrigerants, and intelligent control systems to address the aforementioned pain points, becoming a core tool for food companies to optimize their refrigeration chain.
Core application scenarios and technology adaptation analysis
1. Cold chain logistics center: precise temperature control in all temperature zones
Large cold chain logistics centers need to manage multiple categories of goods simultaneously, such as meat (-18 ℃), seafood (-30 ℃), fruits and vegetables (0-4 ℃), and dairy products (2-8 ℃). Traditional multi split systems suffer from slow temperature zone switching and high energy consumption.
CBFI Solution:
Modular zone temperature control: Through the parallel design of multiple modules, independent control of different temperature zones is achieved.
Intelligent load allocation: dynamically matching temperature zone demand to avoid energy waste;
Energy saving design: Compared with traditional air-cooled units, the water-cooled system can save 20% -25% energy in continuous low-temperature scenarios, and can save about 8% -10% of annual electricity bills.
The temperature fluctuation range of each temperature zone is ≤ 0.3 ℃, reducing the formation of ice crystals on the surface of frozen meat;
The energy consumption cost of cold storage has been reduced by 22%, saving approximately 150000 yuan in electricity bills annually;
• Support rapid expansion to 700kW to meet the warehousing needs during the peak season of e-commerce.
2.Food processing: precise control of process temperature
Typical scenario:
Meat quick freezing: The center temperature of the meat should be lowered to -18 ℃ within 30 minutes to prevent cell rupture and softening of the meat;
• Dairy fermentation: Yogurt fermentation requires maintaining an environment of 42 ℃± 1 ℃, as overheating or undercooling can affect flavor and nutrition;
Pre cooling of fruits and vegetables: Within 2 hours after picking, quickly reduce the temperature to the refrigeration standard (such as 1 ℃ for apples).
CBFI technology advantages:
Rapid cooling capability: The twin-screw compressor can achieve a cooling rate of ≥ 15 ℃ per hour, meeting the demand for rapid freezing of meat;
Fine tuning temperature control: achieved precise temperature control of ± 0.2 ℃ through electronic expansion valve and proportional integral controller (PID);
Stability guarantee: The compressor can still maintain stable operation in high-temperature and high humidity processing workshops, avoiding shutdown due to vibration or high temperature.
3. Fermentation and refrigerated storage: long-term stable operation guarantee
Fermentation processes such as yeast, bacterial strains, and alcoholic beverages require a constant temperature and humidity environment, and temperature fluctuations exceeding 1 ℃ may lead to product spoilage or abnormal flavor. The refrigerated warehouse needs to maintain a constant temperature for 24 hours to prevent food dehydration or freezing.
Characteristics of CBFI scheme:
Long term stable operation: The water cooling system reduces the impact of external environments (such as direct sunlight and dust) on the condenser, and the unit can operate continuously for 8000 hours without any faults;
Humidity collaborative control: Some models can be linked to a dehumidification system to ensure that the humidity in the fermentation workshop is within the range of 55% -65%;
Noise suppression: Adopting a low-speed compressor and soundproof cover design, the workshop noise is controlled below 65dB, improving the working environment.
4. Baking and Beverage Manufacturing: Temperature Connection in the Process Stage
Bread fermentation requires expansion at 38 ℃ first, followed by rapid cooling to 2 ℃ for rapid freezing and freshness locking;
Before and after beer filling, the temperature inside the barrel should be lowered from 20 ℃ to 4 ℃ to avoid the escape of CO ₂ and affect the taste.
CBFI flexible adaptation:
Rapid temperature change capability: By switching between a variable frequency compressor and cooling water circulation, the temperature can be reduced from 40 ℃ to -5 ℃ within 10 minutes;
Process connection optimization: Customized temperature curve programming to match multi-step process requirements such as baking and filling;
The widespread application of CBFI industrial water-cooled chillers in the food industry not only solves the shortcomings of traditional refrigeration systems in accuracy, energy efficiency, and stability, but also promotes the transformation of the food industry towards intelligence and greenness through technological innovation. From the full temperature control of cold chain logistics to the fine parameter control of processing technology, its scene adaptation ability and reliability are reshaping the safety and efficiency standards of the food industry. In the future, with the diversified demands of food processing scenarios, CBFI will continue to deepen its cultivation in segmented fields, helping enterprises win market competitiveness through refrigeration technology innovation.
