In the field of food processing and cold chain logistics, quick freezing equipment, as the technical carrier of the core link, directly affects product quality, production efficiency, and cost control. Faced with higher market demands for food shelf life, nutrient retention rate, and large-scale production, the limitations of traditional quick freezing technology are gradually becoming apparent. The CBFI (Icesource) double helix quick freezing machine, with its innovation in material technology, transmission system, and structural design, has become a solution in the modern food industry that combines efficiency, stability, and reliability.
1. Structural Design and Material Application: From Basic Construction to Reliable Performance
The core structure of the CBFI double spiral quick freezing machine consists of a rotating cage, a bracket, a support rail, and a conveying system. Its design logic aims to achieve "high precision" and "long service life". Firstly, the selection of all stainless steel material runs through the entire cage and support system, which is based on the corrosion resistance and deformation resistance of stainless steel, as well as the hygiene standards in the food processing industry. In the treatment of food contact surfaces, the polishing process of the inner wall of the cage and the support rail can reduce the risk of food residue adhesion, while the modular design of the bracket facilitates disassembly and cleaning, reducing the possibility of cross contamination.
In critical areas of the transmission system, traditional metal contact surfaces are replaced by polymer polyethylene friction reducing materials. This innovation not only solves the problem of metal components becoming brittle and increasing friction coefficient in low-temperature environments, but also reduces mechanical losses through the self-lubricating properties of the material. For example, by using polymer materials at the contact points between the conveyor belt and the support rail, the operating resistance can be reduced by about 30%, thereby reducing the energy consumption of the transmission system and extending the service life of the equipment.
2. Transmission System Innovation: From "Single Drive" to "Multi Dimensional Collaboration"
Traditional quick freezing machines often suffer from decreased efficiency or increased failure rates due to the difficulty of dealing with high loads or complex working conditions with a single transmission device. CBFI's solution is to establish a dual system of "low tension synchronous transmission+auxiliary transmission".
• Low tension synchronous transmission technology: By optimizing the coordination between the gearbox and the motor, the conveyor belt maintains a constant tension during operation. This design avoids the impact of traditional high tension transmission on the chain during start-up or emergency stop, while reducing the probability of chain elongation and deformation. Actual test data shows that under low tension mode, the fatigue life of the chain can be increased by more than 40%.
• Auxiliary transmission device: As a redundant design, this device can take over immediately in case of abnormalities in the main system, ensuring the continuous operation of the production line. For example, when extreme low temperatures cause changes in the viscosity of transmission grease, the auxiliary system can adjust the torque output through intelligent frequency conversion to maintain stable rotation of the cage.
• Multi frequency converter collaborative control: The system is equipped with multiple independent frequency converters, which achieve precise speed regulation in different areas through distributed control strategies. For example, for the feeding and discharging areas of Yikatun, the frequency converter can automatically adjust the speed difference to avoid product accumulation or conveyor belt slippage, thereby increasing production efficiency by about 25%.
In addition, the high-strength spiral specialized horseshoe conveyor belt is the core component of the transmission system. Its structure adopts a chain link design similar to a "horseshoe" shape, which not only increases the contact area with food to ensure uniform force distribution, but also enhances tensile strength through spiral arrangement. This conveyor belt has passed the Ashworth standard certification in the United States, with a breaking strength of 12000 N (newtons), far exceeding the industry standard of 8000 N, and can withstand impact loads under continuous heavy load conditions.
3. Performance advantages: Multi scenario adaptation and energy saving and consumption reduction
The technological advantages of CBFI double spiral quick freezing machine are not only reflected in the hardware level, but also demonstrate multiple values in actual production:
• Fast and uniform freezing:
Through the design of a double spiral structure, the product completes a 360 ° cycle of freezing along a helical path during transportation. The cold air flow penetrates the product gap in a turbulent manner, ensuring that the core temperature can reach below -18 ℃ within 15 minutes in a freezing environment of -30 ℃ to -40 ℃. Compared with the linear freezer, its freezing time is shortened by about 30%, and due to the uniform distribution of cooling capacity, the surface dry consumption rate of the product is reduced to less than 1.5%.
• Intelligent energy consumption management:
The multi-level regulation capability of the frequency converter enables the equipment to dynamically adjust the power output according to the production load. For example, during low production periods at night, the system automatically switches to economy mode, reducing the operating frequency of compressors and fans, which can reduce energy consumption by 20% -30%. In addition, the low friction coefficient and structural optimization of the conveyor belt further reduce the energy loss of the transmission system, and the overall energy efficiency ratio (EER) of the machine has been improved to over 3.2, far exceeding the 2.5 of ordinary quick freezing equipment.
• Maintain convenience and security:
The modular design shortens the replacement time of key components such as conveyor belts and mesh plates to within 2 hours, while the intelligent fault diagnosis system can monitor the equipment status in real time through vibration sensors and temperature probes, and warn in advance of hidden dangers such as bearing wear or motor overheating. In terms of safety protection, the rotating cage adopts a double-layer stainless steel shell and is equipped with an emergency stop button and temperature interlock device to ensure that operators stay away from the risk of low-temperature injuries.
4. Industry Applications and Market Prospects
The application of CBFI double spiral quick freezing machine has covered multiple fields such as aquaculture, meat, and fruit and vegetable processing. In practical cases:
• Aquaculture industry: After a salmon processing plant adopted this equipment, the ice crystals inside the fish meat became finer and more uniform. After thawing, the juice loss rate decreased from 8% to 3%, and the appearance integrity of the product increased by 40%. The single batch processing capacity increased by 20 tons/day.
• Quick frozen pastry: For products that are prone to deformation such as buns and dumplings, the double spiral structure of slow conveying avoids the problem of extrusion deformation, increasing the yield rate to 98%.
• Cold chain logistics: In the meat cutting workshop, equipment is linked with automated sorting lines to achieve seamless connection from processing to quick freezing, with temperature fluctuations controlled within ± 1 ℃ throughout the entire process, significantly extending product shelf life.
The breakthrough of CBFI (Icesource) double spiral freezing machine lies in the deep integration of mechanical engineering, materials science, and low-temperature physics technology, which solves the pain points of low efficiency, high energy consumption, and complex maintenance of traditional quick freezing machines. Every optimization of its technical details, from the selection of stainless steel materials to the intelligent control of multiple frequency converters, is based on actual production scenarios, demonstrating the pragmatic logic of technology serving the industry. With the increasing demand for "precision refrigeration" and "sustainable manufacturing" in the food processing industry, such innovative and reliable equipment will become a key technological pivot for enterprises to achieve cost reduction, efficiency improvement, and enhance market competitiveness.
