Efficient continuous freezing technology, enabling large-scale production
Employs a fully automated continuous tunnel freezing design. Shrimp products move steadily and uniformly on a conveyor mesh belt through a freezing tunnel of customizable length, seamlessly integrating with upstream cleaning/grading/tray-loading equipment and downstream packaging machines. This design enables efficient 24/7 non-stop production with high throughput and stable production rhythm, making it an ideal solution for handling seasonal fishing peaks and large-scale orders.
Super strong wind field and precise temperature control achieve the "single-piece quick freezing" (IQF) effect
Utilizes high-efficiency fans and precise air duct systems to create a powerful, uniform, and multi-directionally penetrating circulating ultra-low temperature airflow within the tunnel. This airflow rapidly removes heat from the shrimp surface, ensuring each shrimp achieves uniform internal and external freezing in the shortest time, forming tiny ice crystals and minimizing drip loss. It effectively prevents shrimp from sticking together, achieving high-quality IQF (Individual Quick Freezing) results with excellent appearance and taste.
Modular design for flexible customization, precisely matching production demands
Key parameters of the equipment, such as tunnel length, mesh belt width, number of freezing zones, refrigeration power, and air velocity settings, can all be deeply customized on a modular basis according to the client's specific capacity goals (e.g., processing capacity can be tailored from 300 kg/h to 8000 kg/h or higher) and shrimp product types (e.g., peeled shrimp vs. whole shrimp). We are committed to providing personalized freezing solutions that best fit the production plans, budgets, and product characteristics of clients at various development stages.
Intelligent Control and Hygiene Design
Equipped with a full-color touch-screen intelligent control system for precise setting, monitoring, and recording of temperature, air velocity, belt speed, and running time in each freezing zone, ensuring process stability and data traceability. The equipment features an all-food-grade stainless steel structure with smooth, crevice-free surfaces that are easy to thoroughly clean and sanitize, fully complying with international food safety standards such as HACCP and BRC, providing the highest level of safety assurance for shrimp processing.
Impact tunnel quick freezer
Speed adjustable
Utilizes high-velocity, ultra-low-temperature airflows to rapidly crust-freeze products, minimizing dehydration and ice crystal formation. This quick passage through the “danger zone” effectively locks in original moisture, flavor, texture, and nutritional value.
A wide range of applications
Applied in fruit, seafood, meat and other granular and block food frozen
It covers a small area
Small floor area, compared with the conventional quick-freezing machine to reduce the quick-freezing machine installation space
Continuous Operation, Maximizes Output
Provides true 24/7 non-stop freezing capability. Products enter and exit continuously, eliminating batch cycle waiting times and dramatically increasing overall plant throughput compared to batch-type freezers.
High Efficiency & Uniformity
Advanced airflow design and precision temperature control ensure every product receives identical freezing conditions, guaranteeing consistent quality. Energy recovery systems optimize thermal efficiency, reducing operational costs.
Our company one-stop set of quick-frozen solutions, using domestic and foreign advanced refrigeration design concept multiple parallel units, no barrel no pump technology, through the PLC in the program automatic energy adjustment to match the ever-changing cooling cooling that the refrigeration system maintain the best efficiency, to achieve energy saving, reduce operating costs.
1. Multiple units are connected in parallel and multi-level energy regulation is used to achieve timely and reasonable matching according to the actual refrigeration capacity required for production, which saves more than 30% energy compared with a single unit.
2.It can match multiple evaporators to achieve one machine suitable for different evaporation temperatures, making the refrigeration system run in the most energy-saving working state.
3. Adopt high-quality compressors and accessories from home and abroad, with reliable performance, stable operation and long service life.
4. Simple design, the refrigeration main unit, accessories and controls are concentrated in one body, which fully saves the machine room space and is extremely convenient for operation and maintenance.
5. The use of fault separation technology can ensure that when some machines fail, other machines can still operate normally, ensuring normal and continuous production for customers.
STC series evaporative condensers are the latest type of evaporative condensers developed by our company by absorbing the latest technologies and manufacturing processes at home and abroad. They are one of many types of condensers and are widely used due to their energy and water saving, high efficiency and low operating cost.
When the equipment is running, the refrigerant in the coil is reversely exchanged by the cooling water from top to bottom and the natural air from bottom to top, and the heat is taken away from the air; the water passing through the coil flows into the packing layer and then flows into the water pan after being cooled. The small water droplets passing through the top layer are collected by the water collector, thus reducing the water escape rate.
