【 Quick freezing type 】 Quick frozen aquatic products
In Southeast Asia, Thailand is one of the world's important seafood exporting countries, and its shrimp farming and processing industry holds a pivotal position in the global market. With the continuous improvement of international customers' requirements for the quality of frozen shrimp, traditional cold storage freezing methods are no longer able to meet the production needs of high quality and efficiency. To this end, CBFI Ice Spring Refrigeration has tailored a 750kg/hour plate and belt tunnel quick freezing system for a large seafood processing plant in Thailand, specifically designed for rapid freezing of shrimp.
[Project Background] Current Status of Shrimp Processing and Cold Chain in Thailand
Thailand is located in a tropical climate zone, with abundant marine resources and a mature aquaculture system, and is one of the world's major exporters of shrimp products. There are numerous shrimp processing enterprises in the country, and their products are widely exported to the European, American, Japanese, and Chinese markets.
However, in the cold chain logistics process, many enterprises still use traditional cold air storage or intermittent freezing technology, which has problems such as slow freezing speed, high energy consumption, product deformation, and serious surface dry consumption, seriously affecting the quality and export price of shrimp. After examining multiple brands, the customer ultimately chose to cooperate with CBFI, hoping to improve product quality, expand production capacity, and enhance international market competitiveness by introducing advanced quick freezing equipment.
[Customer Requirement Analysis]
·Daily production requirement: Processing about 6 tons of shrimp per day, with an average of about 750kg frozen per hour;
·Product specifications: Peeled&Developed Shrimp, with an initial temperature of approximately 15 ℃;
·Quality requirements: Maintain the original shape of the shrimp, without deformation, adhesion, and natural color;
·Target temperature: Center temperature after freezing ≤ -18 ℃;
·Supporting environment: The existing factory space is limited, and a compact equipment layout needs to be customized; Energy saving and maintainability: We hope that the equipment has high-efficiency and energy-saving characteristics, making it easy for daily maintenance.
[CBFI Solution: 750kg/h Plate and Strip Tunnel Freezing System]
In response to the actual needs of customers, CBFI dispatched a technical team to conduct on-site research at the Thai factory to gain a deep understanding of key factors such as the status of shrimp raw materials, workshop layout, power conditions, and local climate environment. Based on the daily production data and product parameters provided by the customer, an efficient and stable plate and strip tunnel quick freezing system was designed.
[Equipment Configuration]
·Quick freezing machine type: Plate and strip tunnel quick freezing machine
·Quick freezing capacity: 750 kg/h
·Condensation method: Evaporative Condenser
·Cold storage size: 1500 × 2000 × 2720mm
·Freezing temperature: The minimum working temperature inside the warehouse can reach -35 ℃
·Center temperature of frozen product: ≤ -18 ℃
·Mesh belt material: food grade 304 stainless steel plate belt, ensuring hygiene and safety
·Transmission system: Variable frequency speed control, adapted to different freezing time requirements
·Control system: PLC+touch screen fully automatic control, supports remote monitoring
[Detailed explanation of technical advantages]
1. Plate and strip structure to prevent shrimp deformation
Compared to the mesh belt freezer, the plate belt conveyor is smoother and denser, which can effectively avoid shape changes caused by vibration or sinking of shrimp during the freezing process, ensuring the integrity and beauty of the product appearance.
2. Quickly freeze, lock in nutrients and taste
At a low temperature of -35 ℃, shrimp can freeze in a short period of time, reducing the formation of ice crystals in cells, thus preserving its original moisture, taste, and nutritional value.
3. Evaporative cooling system, energy-saving and stable
Using evaporative cooling as the condensation method has higher heat transfer efficiency compared to air-cooled condensers, especially suitable for the high temperature and high humidity climate environment in Thailand, with more stable operation and lower energy consumption.
4. Intelligent control system, easy to operate
Equipped with a PLC automation control system, it can monitor and adjust parameters such as temperature, wind speed, and conveyor belt speed in real time to ensure the continuity and consistency of the freezing process. At the same time, it supports remote diagnostic functions for easy maintenance in the later stage.
5. Compact design, saving space
According to the customer's on-site conditions, the entire quick freezing system adopts modular design, compact structure, flexible installation, fully utilizes limited space, and is easy to expand in the future.
[Project Implementation and Customer Feedback]
CBFI engineers were fully involved in the entire process from scheme design to on-site installation and commissioning, and provided on-site guidance for two weeks to ensure the smooth commissioning of the equipment and achieve the expected results.
The strip freezing system from CBFI fully meets our production needs, not only improving product quality but also significantly increasing production efficiency. Now our shrimp has gained higher customer recognition when exported. "The customer manager stated.
At present, the system is running stably and the customer feedback is good. The frozen shrimp can be directly stored in a -18 ℃ cold storage for a long time, greatly extending the shelf life, reducing the loss rate, and enhancing the competitiveness of the product in the international market.
