1. Fruit & Vegetable Farms & Agricultural Processing Plants
Our fresh-keeping cold storage is specially designed for farms and agricultural processing plants. With precise temperature and humidity control, it effectively slows down the respiration of fruits, vegetables and grains. This helps reduce post-harvest losses, extend shelf life, and support off-season sales, bringing significant economic benefits to agricultural production.
2. Supermarkets, Chain Stores & Catering Enterprises
Widely used in supermarkets, retail chains and catering companies, the cold storage ensures fresh storage of meat, seafood, dairy, beverages and prepared food. It maintains stable quality and original taste, supporting daily operations while reducing waste and improving overall operational efficiency.
3. Cold Chain Logistics & Distribution Centers
Ideal for cold chain logistics centers and wholesale warehouses, the storage provides reliable temporary storage and transshipment for perishable goods. It ensures consistent temperature during transit and storage, preventing spoilage and ensuring food safety, which is critical for the entire cold chain logistics system.
4. Food Processing Factories & Pharmaceutical Warehouses
Suitable for food processing factories and pharmaceutical warehouses, the cold storage offers a stable low-temperature environment for raw materials, semi-finished products and finished goods. It helps preserve product quality and consistency, meeting strict industry standards for food and drug storage.
5. Home Brewing, Beverage & Food Small-Scale Production
Perfect for micro-breweries, beverage factories and small-scale food processing workshops, the storage supports long-term storage of raw materials, semi-finished products and finished beverages. It maintains stable conditions during production cycles, ensuring product consistency and quality control.
一、How to Choose a Fresh-Keeping Cabinet
When choosing a fresh-keeping cabinet, you need to consider the type and quantity of food as well as your actual family situation. Ordinary household fresh-keeping cabinets usually come in three types: refrigerated, frozen, and combined. Refrigerated fresh-keeping cabinets are suitable for short-term storage of foods such as vegetables, fruits, and meats, and are relatively inexpensive. Frozen fresh-keeping cabinets can store foods for long-term freshness preservation, such as fish, meats, and dairy products, and are relatively costly. Combined fresh-keeping cabinets integrate the functions of both refrigerated and frozen types, enabling both short-term freshness preservation of foods and long-term storage of perishables, but they are also relatively high-priced. Therefore, when selecting a fresh-keeping cabinet, you need to make a choice based on your actual needs.
二、How to Use Your Fresh-Keeping Cold Storage
1. Clean the Cold Storage
Before first use, thoroughly clean the unit. Remove all debris, wipe the interior with a damp cloth (avoid harsh detergents). Also clean the exterior, especially the door seal rubber gasket, to ensure proper insulation and sealing.
2. Loading Food
Before placing food in the cold storage, prepare and load items properly:
Classify and store similar foods together by type.
Arrange items neatly without overcrowding to ensure good air circulation and preserve freshness.
Only store fresh, non-expired food to maintain overall storage quality.
3. Temperature Control for Fresh-Keeping Cold Storage
Temperature control is critical for food preservation. Different foods require specific temperatures to maintain freshness and shelf life:
Refrigerated cold storage: Keep at 0°C~6°C, ideal for short-term fresh food storage.
Frozen cold storage: Maintain around -18°C, suitable for long-term preservation of frozen goods.
Combined cold storage: Adjust temperature based on food types.
Pay extra attention to temperature control in hot summer to ensure food freshness.
4. Cold Storage Door Operation
When retrieving food, pay attention to the door operation. Before opening, check the door seal with your hand to ensure it is tightly sealed and prevent cold air leakage. After taking out items, close the door promptly to avoid large temperature fluctuations inside the cold storage.
5. Regular Cleaning & Maintenance
To maintain optimal freshness and extend service life, clean the cold storage regularly during long-term use. Wipe the interior with a damp cloth periodically (avoid detergents to prevent food safety risks). Also conduct routine inspections: check for seal aging, cooling system performance, and other key components to ensure stable operation.
三、Cold Storage Maintenance Tips
1. Avoid Prolonged Operation
Do not run the cold storage continuously for too long. Set the appropriate temperature and power off in a timely manner. Extended operation will lead to excessive power consumption and may reduce the freshness.
2. Avoid Overloading
Overcrowding inside the cold storage will raise the internal temperature, compromising food freshness. Therefore, avoid overloading during use, and reasonably distribute the food load on each shelf to ensure proper air circulation and stable temperature.
3. Keep Spare Ice Blocks on Hand
Spare ice blocks can be used during power outages. For transportation or long periods of on/off operation, place pre-chilled ice blocks inside the cold storage to extend freshness duration and provide additional cooling effect.
4. Pay Attention to Food Packaging
Before placing food in the cold storage, pack it properly. Store items in sealed bags or containers to prevent moisture evaporation and maintain freshness. Additionally, use different packaging methods for different types of food to ensure optimal preservation.
