Efficient continuous freezing technology, enabling large-scale production
Employs a fully automated continuous tunnel freezing design. Dumplings move smoothly and uniformly on a conveyor belt through the entire freezing process, achieving seamless integration with upstream forming machines and downstream packaging equipment. This genuine流水线 operation eliminates production bottlenecks and ensures extremely high continuity from raw materials to finished products, serving as the cornerstone for large-scale, high-efficiency dumpling production.
Super strong wind field and precise temperature control achieve the "single-piece quick freezing" (IQF) effect
Utilizes an optimized air duct system to create a circulating airflow with ultra-high velocity and uniform temperature within the tunnel. The powerful cold air rapidly envelops and penetrates each dumpling, causing the surface to set quickly and the interior to freeze uniformly in a short time. This effectively prevents dumplings from sticking together (clumping) and avoids tray marks, achieving perfect IQF (Individual Quick Freezing). The final product is easy to separate and package.
Modular design for flexible customization, precisely matching production demands
Equipment length, mesh belt width, freezing capacity, and refrigeration configuration can all be modularly customized based on the client's target hourly/daily output and plant conditions (e.g., processing capacity can be tailored from 500 kg/h to 5000 kg/h or higher). We offer a complete range of solutions from compact to ultra-large models, ensuring a tailor-made dumpling quick-freezing production line with the optimal return on investment for each client.
Intelligent Control and Hygiene Design
Integrates an intelligent control system for real-time monitoring and automatic adjustment of parameters in each freezing zone, ensuring process stability. The equipment features an all-stainless-steel construction compliant with food-grade hygiene standards, with no cleaning dead ends. An optional CIP (Cleaning-in-Place) system is available, greatly simplifying maintenance and ensuring production safety and compliance.
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.
