[0℃~15℃] Fruit and vegetable freshness preservation storage | Extends freshness preservation period by 6-8 months | Reduces loss rate | Factory direct quotation

Unlike simple "freezing", the fresh-keeping cold storage maintains a precise and suitable low temperature environment of **0℃ to 15℃**, effectively inhibiting the respiratory intensity and microbial activity of fruits and vegetables after harvesting.

Whether it's Lianjiang red orange or Yuncheng red fragrant crisp pear, professional refrigeration and preservation facilities can not only extend the storage period by 6-8 months, but also enhance the premium pricing ability of agricultural products through off-peak sales, which is the key to achieving "one season storage, four seasons sales".

Core product advantages (H2): Precise temperature control and long-lasting design

1. High-efficiency insulation body: dual options of polyurethane/polystyrene board

 The body of the cold storage adopts rigid polyurethane or polystyrene foam insulation sandwich panels, which are molded in one go through high-pressure foaming process. It has an extremely low thermal conductivity, effectively isolating internal and external heat exchange. For small rural cold storage scenarios, it is recommended to use 100mm-150mm thick panels to ensure stable temperature in the cold storage even under high temperature conditions in summer, saving more than 30% energy compared to ordinary buildings.

2. Brand refrigeration unit: fully enclosed/semi-enclosed compressor solution

 For common small-sized storage capacities ranging from 10 tons to 100 tons, we offer both fully enclosed scroll compressors (suitable for temperatures above 0℃) and semi-enclosed piston compressors (suitable for temperatures at and below -18℃) as optional configurations. Supporting both air-cooled and water-cooled cooling methods, these compressors feature low failure rates and minimal noise, making them particularly suitable for installation near villages or residential areas.

3. Automatic frosting and intelligent electronic control

 Equipped with a microcomputer-based intelligent temperature controller, it features fully automatic constant temperature, automatic scheduled defrosting, and temperature overrun alarm functions. Users do not need to have someone on duty 24/7, as the digital display provides real-time monitoring of the temperature and humidity inside the warehouse. In the event of a malfunction, the backup protection system is immediately activated to minimize the risk of "warehouse damage" caused by equipment downtime.

4. Flexible customization: one-base dual-temperature and controlled atmosphere expansion

 It supports independent control for each compartment, allowing for zoned management based on the refrigeration requirements of different agricultural products (such as apples requiring 0℃ and potatoes requiring 2-4℃). For high-end fruit storage, it can also be upgraded to an air-conditioned fresh-keeping warehouse, which can put fruits and vegetables into a "dormant" state by reducing oxygen concentration and increasing carbon dioxide concentration, achieving a better fresh-keeping effect than ordinary cold storage.

Application scenarios and storage parameters:

Fresh-keeping cold storage is widely applicable to the storage of fruits, vegetables, flowers, mushrooms, and fresh eggs. The following are typical technical parameters for different products for reference:

| Storage category | Recommended storage temperature (℃) | Expected freshness period |

| **Apple/Pear** | -1℃ ~ +1℃ | 6-8 months |

| **Garlic sprouts/Green onions** | -1℃ ~ 0℃ | 7-10 months |

| **Shiitake Mushroom/Agaricus Bisporus** | 0℃ ~ 2℃ | Extends by 10-15 days |

| **Grapes/Raisins** | -1℃ ~ 0℃ | 4-7 months |

| **Potatoes / Onions** | 2℃ ~ 4℃ | 6-8 months |

| **Lychee/Longan** | 3℃ ~ 4℃ | 30-40 days |

Selection and Quotation Guide (H2): How to Calculate Your Fresh Food Storage Cost?

Fresh-keeping cold storage is a non-standard customized product, and its price is influenced by three factors: size, temperature, and equipment brand. Small-sized cold storage facilities in rural areas (with a storage capacity of 10 to 100 tons) are currently the most cost-effective option.

1. Determine the scale (taking Apple as an example):

10-ton storage: requiring approximately 60-80 cubic meters of storage capacity, suitable for family farms.

50-ton storage: approximately requiring 300-400 cubic meters of storage capacity, suitable for shared use by cooperatives.

2. Cost composition of common configuration schemes:

Insulation: economical solution with polystyrene board vs high-standard solution with polyurethane board.

Refrigeration part: domestic first-line brand units vs imported brand units (with a price difference of about 15%-20%).

Installation auxiliary materials: copper pipe, wire, refrigerant, thermostat, etc.

Common problems: essential questions to be answered before constructing a fresh food storage

Q1: I am a farmer with a limited budget. How can I build a simplest fresh-keeping cold storage?

A: If you have an unused brick-concrete house (windowless and sturdy) at home, we recommend adopting the "civil engineering assembly composite" solution. Keep the walls as external protection, and internally install polystyrene insulation boards and air coolers. The refrigeration unit adopts a wall-mounted design, eliminating the need for a machine room. This approach requires minimal investment and yields quick results.

Q2: Is the electricity cost for running a cold storage facility expensive?

A: The fresh-keeping cold storage (above 0℃) saves a lot of electricity compared to the freezing cold storage (-18℃). Due to the fully automatic control, the compressor stops when the temperature reaches the set value, and the insulation performance of the cold storage body is good, resulting in a low daily average operation rate. The daily average electricity consumption of a 10-ton fresh-keeping cold storage is usually around **20-30 kWh**.

Q3: Under what circumstances is it necessary to build a controlled atmosphere storage?

A: If you are storing high-value kiwis, cherries, blueberries, or need to sell them out of season for more than 10 months, a controlled atmosphere storage facility is a better choice. It can inhibit ethylene production, maintaining better fruit firmness, but the cost is about 40% higher than that of a regular fresh-keeping storage facility.
