Questions Related to Product ApplicationsQ1: What types of products can your company's quick-freezing equipment be used for?A1: Our quick-freezing equipment has a wide range of applications, covering various products that require quick-freezing and preservation across multiple industries, mainly including:Food industry: Meat (pork, beef, mutton, poultry, aquatic products, seafood, etc.), fruits and vegetables (fresh vegetables, fruits, edible fungi, etc.), rice and flour products (dumplings, glutinous rice balls, steamed buns, zongzi, noodles, etc.), prepared foods (ready-to-cook dishes, meatballs, skewers, hamburger buns, etc.), dairy products (ice cream, yogurt blocks, etc.).Other industries: Such as some biological agents in the pharmaceutical industry, some materials requiring low-temperature solidification in the chemical industry, etc. (Customized adaptation solutions can be provided according to the specific characteristics of the materials).Different types of quick-freezing equipment (e.g., tunnel-type, spiral-type, plate-type) can be targeted to match products of different shapes and sizes. For accurate equipment selection, please provide specific product information and our professional staff will assist you.Q2: What advantages does the quick-freezing equipment have in terms of product preservation effect?A2: The core advantage lies in "rapid freshness locking". Through rapid freezing at low temperatures, the core temperature of the product can be reduced to below -18°C in a short time, which effectively inhibits the growth and reproduction of microorganisms, reduces the formation of large ice crystals in the product, thereby maximizing the retention of the product's original nutritional components (such as vitamins, proteins), taste and flavor (such as the crispness of fruits and vegetables, the tenderness of meat) and appearance (avoiding product deformation and juice loss), extends the product shelf life, and does not damage the original quality structure of the product.II. Questions Related to Product OutputQ4: What is the output range of your company's quick-freezing equipment? Can it meet our production capacity requirements?A4: Our quick-freezing equipment has a wide output range, which can meet the different production capacity needs from small and medium-sized merchants to large food processing plants, specifically divided into:Small-sized equipment: Daily output (calculated based on 8 hours) ranges from 500 kg to 5 tons, suitable for small processing plants, central kitchens of catering chains, start-up enterprises, etc.Medium-sized equipment: Daily output ranges from 5 tons to 20 tons, suitable for medium-sized food enterprises and can meet the quick-freezing needs of multiple production lines.Large-sized equipment: Daily output is more than 20 tons, and the maximum customizable daily output is 100 tons, suitable for large-scale mass production scenarios such as large-scale food processing enterprises and cold chain logistics centers.If you have clear production capacity requirements (such as hourly/daily quick-freezing capacity, unit weight of products, etc.), please provide detailed parameters, and we will recommend the most suitable equipment model for you or customize an exclusive production capacity solution.Q5: What factors will affect the actual output of the equipment?A5: The actual output of the equipment is mainly affected by the following 3 core factors:Product characteristics: Initial temperature of the product (room temperature/pre-cooled), water content of the product (the higher the water content, the more energy required for freezing, and the output will decrease slightly), product shape (block/slice/granule, the thicker the product, the lower the freezing efficiency).Freezing requirements: Target freezing temperature (e.g., -18°C/-30°C). The lower the target temperature, the corresponding adjustment of the hourly output will be made.Operating parameters: Conveying speed of the equipment, operating power of the refrigeration system, etc. Reasonable adjustment of parameters can optimize output while ensuring freezing effect (it is recommended to operate under the guidance of professional personnel).Q6: If the production capacity expands in the future, can the existing equipment be upgraded and transformed?A6: Yes. Our equipment is designed with reserved upgrade space. Most medium-sized and large-sized equipment can be upgraded and transformed to increase production capacity, such as extending the length of the quick-freezing tunnel, increasing the number of spiral tower layers, upgrading the power of the refrigeration compressor, optimizing the conveying system, etc. Whether the equipment can be upgraded, the upgrade plan and the improvement range need to be determined based on the existing equipment model, structure and your target production capacity. It is recommended to communicate with our technical team in advance.III. Questions Related to Product Inlet and Outlet TemperaturesQ7: Does the equipment have requirements for the initial temperature of incoming products? What is the optimal inlet temperature?A7: There are basic requirements, and the optimal inlet temperature varies slightly for different products. The core principle is "to avoid excessively high initial temperature of products, which will lead to prolonged freezing time, reduced production capacity, and increased load on the equipment's refrigeration system".General requirements: It is recommended that the initial temperature of incoming products does not exceed 25°C (products at room temperature can be directly fed into the equipment; if products are processed at high temperature, they need to be pre-cooled to below 30°C before entering the quick-freezing equipment).Optimal inlet temperature: It is recommended to pre-cool the product to 0-5°C before feeding. This can greatly shorten the freezing time, improve equipment production capacity, ensure freezing uniformity, and further enhance the product preservation effect (especially suitable for high-water content and perishable products such as fresh fruits and vegetables, aquatic products).If the initial temperature of the product is too high, the equipment can still operate normally, but the conveying speed needs to be adjusted to ensure the freezing effect, and the hourly output will be reduced accordingly.Q8: What is the achievable outlet temperature of the equipment? Can it be adjusted according to needs?A8: 1. Standard outlet temperature: Under conventional configuration, the equipment can stably reduce the core temperature of the product to below -18°C, meeting the national standard requirements for food freezing and preservation (GB 2707-2016 National Food Safety Standard for Fresh (Frozen) Livestock Meat, etc.). After being discharged, the product can be directly transferred to a low-temperature cold storage for storage.Temperature adjustment: It can be customized according to customers' special needs to adjust the outlet temperature to -25°C, -30°C or even lower (such as -40°C), suitable for products with higher freezing temperature requirements (such as high-end seafood, biological agents, special foods requiring long-term storage). Low-temperature customization requires supporting upgrades of the refrigeration system and thermal insulation structure, and specific solutions can be designed according to product needs.Q9: During the operation of the equipment, will the temperature of the inlet and outlet affect the workshop environment? How to control it?A9: Under normal circumstances, there will be slight cold air leakage at the inlet and outlet of the equipment, but it will not have a significant impact on the workshop ambient temperature. We further control cold air loss through the following designs:Equipped with air curtains/insulation doors: High-efficiency air curtains (or insulation soft curtains) are installed at the inlet and outlet to form an air barrier, which blocks cold air leakage and external hot air from entering, and at the same time prevents dust and debris in the workshop from entering the equipment.Optimized equipment sealing structure: The equipment box adopts high-quality thermal insulation materials (such as polyurethane foam), and sealing rubber strips are used at door seams and interfaces to reduce cold air penetration.Reasonable installation location planning: It is recommended to place the equipment inlet and outlet away from workshop heat sources (such as boilers, hot air equipment) to avoid hot air blowing directly to the inlet and outlet, further reducing the impact of the environment on the equipment.Q10: How to detect whether the core temperature of the discharged product meets the standard? Is the equipment equipped with temperature monitoring function?A10: 1. Detection method: A professional food core thermometer can be used. Randomly select products at the discharge port, insert the thermometer probe into the core position of the product (avoiding bones, packaging, etc.), let it stand for 3-5 minutes, and then read the value to judge whether the target freezing temperature is reached.Equipment configuration: All our medium and large-sized equipment are standard-equipped with a real-time temperature monitoring system. Temperature sensors are installed at key positions of the quick-freezing chamber and the discharge port, which can display the chamber temperature and product outlet temperature in real time on the operation panel. Some high-end models support temperature data recording, storage and export functions for easy traceability. At the same time, the equipment can set temperature alarm thresholds, and if the temperature does not meet the standard, it will automatically alarm to remind the operator to adjust parameters.IV. Other Supplementary QuestionsQ11: How to choose different types of quick-freezing equipment (tunnel-type/spiral-type/plate-type)?A11: You can make a priority choice according to your core needs:Tunnel-type quick-freezing equipment: Suitable for block, granule and slice products (such as meat blocks, fruit and vegetable slices, dumplings). Its advantages are stable conveying, uniform product freezing, wide capacity range (daily output 1-50 tons), moderate floor space and convenient maintenance.Spiral-type quick-freezing equipment: Suitable for small-volume and large-batch products (such as glutinous rice balls, meatballs, shrimps). Its advantages are small floor space, high space utilization rate, large production capacity (daily output 5-100 tons), suitable for large-scale production.Plate-type quick-freezing equipment: Suitable for irregular-shaped and large-volume products (such as whole chickens, whole fish, large meat blocks). Its advantages are good freezing effect, strong adaptability to product shapes, suitable for small-batch and multi-variety production, small floor space and simple operation.It is recommended to make a comprehensive choice based on product characteristics, production capacity requirements and workshop floor space. We can provide free equipment selection consulting services.Q12: What is the energy consumption of the equipment? Does it have energy-saving design?A12: The energy consumption of the equipment is related to production capacity, product characteristics and freezing temperature. The hourly energy consumption of a conventional medium-sized tunnel-type quick-freezing equipment (daily output 10 tons, target temperature -18°C) is about 30-50 kWh (subject to actual working conditions).All our equipment are equipped with multiple energy-saving designs: such as high-efficiency frequency conversion compressors, which can automatically adjust power according to load to reduce no-load energy consumption; optimized refrigeration circuit design to improve heat exchange efficiency and reduce energy consumption of the refrigeration system; the equipment box adopts high-density thermal insulation materials to reduce cold air loss; some models can be equipped with waste heat recovery devices, which recover the waste heat generated by the refrigeration system for workshop heating or product pre-cooling, further reducing comprehensive energy consumption.Warm Reminder: If you have other questions not mentioned here, or need to formulate an exclusive plan for specific products, production capacity and working conditions, please feel free to contact our customer service or technical team at any time.

Quick freezing Rapid freezing of food by exposure to a blast of air at a very low temperature. Unlike slow freezing, very small crystals of ice are formed which do not rupture the cells of the food and so the structure is relatively undamaged.A quick‐frozen food is commonly defined as one that has been cooled from a temperature of 0 °C to −5 °C or lower, in a period of not more than 2 hours, and then cooled to −18 °C.The basic principle Mechanical cold storage This method of storing fruits in a good adiabatic building, equipped with mechanical cold storage unit, and according to the variety of fruits on the storage temperature, humidity and ventilation requirements of the cold storage system for human regulation and control , So the storage time longer, the effect is better. A, mechanical cold storage principle. Mechanical cold storage is the use of liquid gas (refrigerant) is very low temperature, it evaporated under low pressure into gas, which absorb heat, to achieve the purpose of cooling. In addition to the low boiling point refrigerants, but also requires no harm to human organs, the metal does not play a corrosive effect, no risk of combustion and explosion, does not react with the lubricant, but also should have good heat absorption, evaporation More heat absorption, low pressure in the high pressure condensing system, lower viscosity and cheaper prices.Related Products：Feature of instant freezer , Tunnel  freezer ,Spiral freezer ,IQF freezer
