Large Refrigerators Can’t Meet Fresh-Keeping Needs? Cold Storage Units Offer Precise Temperature Control to Extend Food Shelf Life

        Sister Li, who engages in high-quality fruit wholesale, once suffered heavy losses due to fresh-keeping problems: she stored imported cherries in large refrigerators. Although the set temperature was 0℃, the temperature difference inside the refrigerators was as high as ±3℃. Cherries near the air outlets were frostbitten, while those far away were prone to softening and spoilage. A batch of goods worth 80,000 yuan ended up with a 30% loss. She tried adding more refrigerators and adjusting the placement, but never solved the temperature difference problem.

         After switching to a professional cold storage unit, Sister Li’s fresh-keeping dilemma was completely resolved. Equipped with a high-precision temperature control system, the cold storage unit achieves a temperature control accuracy of ±0.5℃, ensuring uniform temperature throughout the warehouse without local overcooling or overheating. In such an environment, the shelf life of cherries extended from 7 days to 15 days, and the loss rate dropped to below 5%. Moreover, the cold storage can set temperatures in different zones according to the needs of various foods: 0-4℃ for fruits and vegetables, -18℃ for frozen products, and -60℃ for high-end seafood, meeting multiple fresh-keeping needs with one device.

        Compared with large refrigerators, the fresh-keeping advantage of cold storage units is also reflected in humidity control. Equipped with a dedicated humidification/dehumidification module, it can stabilize the warehouse humidity at 85%-90% (the optimal humidity for fruit preservation), preventing food from losing luster and texture due to dryness and dehydration. Sister Li did the math: after using the cold storage unit, the monthly food loss decreased by more than 20,000 yuan. Although the initial investment is higher than that of large refrigerators, the cost can be recovered in 3 months. For merchants who value food quality and rely on long-term fresh-keeping, the temperature control accuracy and humidity adjustment capability of large refrigerators are far from sufficient—cold storage units are the core equipment to ensure the value of goods.
