Temperature and humidity-controlled container that maintains the freshness of freshly harvested vegetables, fruits, and flowers for a long time.
A groundbreaking method creates a windless environment with constant high temperature and humidity (over 98%) inside the storage, remarkably extending the freshness of vegetables, fruits, and flowers, contributing to the reduction of food waste.
To store freshly harvested items for a long time in a refrigerator or similar environment, it is necessary to create the same conditions as when they were cultivated. Using the traditional cooling method of blowing cold air causes the items being cooled to cool down while simultaneously drying out, which accelerates deterioration and leads to waste. Therefore, the "constant temperature and humidity container" has corner pipes that are in contact with the walls inside the container, through which a coolant (brine) cooled by a chiller unit circulates, cooling the entire wall surface. This allows for cooling the stored items inside the container in a no-wind environment, preventing drying by cooling without breaking the moisture barrier surrounding vegetables, fruits, and flowers. Additionally, since the entire wall surface acts as a cooling body, it minimizes temperature fluctuations inside the container. Moreover, a special micro-mist humidification device maintains humidity levels above 98%. However, there is no occurrence of water droplets adhering to the surfaces of vegetables and fruits, nor is there any moisture in the cardboard, which is common in high-humidity environments. In this way, by maintaining the freshness and quality of freshly harvested items for an extended period and reducing waste due to deterioration, we significantly contribute to the SDGs.

basic information
The shipping containers used for "temperature and humidity-controlled containers" are designed to withstand harsh environments at sea, making them highly durable. The walls and ceiling inside the container are made entirely of stainless steel, while the floor is made of aluminum, and the insulation thickness is 80 millimeters, allowing for prolonged refrigeration. The exterior is made of sturdy 3.2-millimeter thick steel. A roller conveyor will be installed on the floor, enabling pallet-based loading and unloading. Additionally, by adding a sliding door on the side, manual loading and unloading as well as first-in-first-out operations become easier. Since it is a container, it can be easily installed and moved like a prefabricated warehouse, and it can be set up outdoors. Specifications of the temperature and humidity-controlled container: Internal dimensions (mm) Length × Width × Height ■ 40-foot type: 11,618 × 2,286 × 2,507 ■ 20-foot type: 5,450 × 2,292 × 2,580 * The effective internal dimensions may vary due to the installation of humidifying equipment and piping inside. * There may be slight dimensional differences depending on the container manufacturer, model, and refrigeration equipment. ■ Internal temperature: +5℃ to +15℃ ■ Refrigerant (brine) temperature: -5℃ to +5℃ ■ Internal humidity: 98% to 30%
