Fruit Cold Storage

Concept:
Fruit and vegetable cold storage preservation is a method that inhibits the activity of microorganisms and enzymes, extending the storage life of produce. Cold storage preservation technology is the primary method for modern low-temperature preservation of fruits and vegetables. The preservation temperature range for fruits and vegetables is 0℃ to 15℃, and preservation storage can reduce the incidence of pathogens and the rate of fruit rot. It also slows down the respiratory metabolic process of fruits and vegetables, thereby preventing spoilage and extending the storage period. The emergence of modern freezing equipment has allowed preservation technology to be applied after rapid freezing, significantly improving the quality of preserved fruits and vegetables.

Advantages:
Modified Atmosphere Storage (MAS) for fruits controls the proportions of nitrogen, oxygen, carbon dioxide, ethylene, and humidity, as well as temperature (above the freezing point) and pressure. It slows down the metabolic process of stored items by reducing their cellular respiration, keeping them in a near-sleep state rather than dead. This preserves the texture, color, taste, and nutrition of the stored fruits for an extended period, achieving long-term preservation. Even after being removed from the MAS environment, the stored items' cells will maintain a normal metabolic rate akin to natural conditions, preventing rapid spoilage and maturation.

Features:
(1) Wide Application Range: Suitable for preserving and cooling various fruits, vegetables, flowers, seedlings, and more across the north and south of our country.
(2) Long shelf life and high economic returns. For example, grapes can be preserved for 7 months, apples for 6 months, and scallion shoots for 7 months, maintaining their freshness and tenderness. Total loss is less than 5%. The market price for grapes at the source is only 1.5 yuan/kg, but the price can reach 6 yuan/kg around the Spring Festival. A one-time investment in building a cold storage can last for 30 years, offering significant economic benefits. The investment pays off in the same year.
(3) Simple operation and easy maintenance. The refrigeration equipment is microcomputer-controlled for temperature, featuring automatic start-up and shutdown without the need for constant supervision, and comes with practical and cost-effective technology.
