Pitaya, a fruit of tropical and subtropical regions, thrives in bright light, tolerates shade, heat, and drought, and prefers fertile but can endure poor soil. When pitaya matures, it is typically during the hot and rainy summer and autumn seasons. The fruit has a high water content and strong respiration after harvesting. During storage, the respiration rate gradually decreases, exhibiting characteristics of non-climacteric fruit respiration. If stored at room temperature, the scales may yellow, the rind may lose water and wrinkle, and the fruit may lose weight and water, even rotting and losing its edible value. Today, we share a simple case of pitaya storage in a cold storage facility by ARTECO Refrigeration.

Project Location: Guizhou

Project Scale:

The cold storage covers an area of about 660 square meters with a total volume of 2300 cubic meters. It is meticulously divided into eight independent spaces, including two precoolings, four controlled-atmosphere storages, and two general preservation storages. This layout not only meets the storage needs of different varieties of pitaya but also ensures precise control of the storage environment.

Refrigeration Method:

The project adopts an environmentally friendly fluorine refrigerant system, which not only aligns with current environmental trends but also ensures the stability and uniformity of the temperature inside the cold storage.

Equipment Configuration:

For refrigeration equipment, the project selects imported Copeland compressor units, favored for their powerful cooling capacity and cost-effectiveness. Additionally, the high-efficiency and energy-saving coolers from Guangdong Advanced Refrigeration are equipped to further enhance the cooling speed and energy efficiency ratio. The structure of the storage is built with flame-retardant polyurethane double-sided color steel plates, strictly following the cold storage construction standards to ensure the safety and thermal insulation performance of the cold storage.

A highlight of the project is its fully automated control system, which features temperature and humidity alarms, data logging, and remote monitoring via mobile clients. This allows managers to grasp the operating status of the cold storage at any time and adjust storage conditions promptly, ensuring that the pitaya is always in the best preservation state.
