Fresh produce starts losing quality as soon as it leaves the field. Field heat, respiration, moisture loss, mixed loading temperatures, and slow transfer between processing areas can shorten storage life before the refrigeration plant has a fair chance to help. A cold room alone will not fix these problems. The real job is to connect precooling, processing, storage, quick freezing, airflow, and control around the actual movement of the product.
Founded in 1956, MOON-TECH marks its 70th anniversary with experience in industrial refrigeration, food cooling, system engineering, and turnkey project delivery. Its operations cover more than 120 countries and regions, supported by nine industrial parks and a broad product chain. Rather than treating each machine as a separate purchase, the company’s Fruit and Vegetable Processing solution brings precooling, controlled atmosphere storage, deep processing, and quick freezing into one practical route. The goal is simple: help you remove heat early, keep storage conditions stable, and avoid paying for refrigeration capacity that does not match the plant.
What Should an Integrated Precooling and Cold Storage Solution Include?
A workable design begins with the produce, not the equipment catalogue. You need to know what arrives, how warm it is, how fast it must cool, how long it will stay, and whether it will leave fresh, cut, packed, or frozen. These answers shape every later decision.
Harvest-to-Dispatch Process Mapping
Map each movement from receiving and washing to grading, packing, storage, freezing, and dispatch. Long waiting points matter. A pallet left in a warm loading area for two hours can undo careful temperature control farther down the line.
Produce-Specific Temperature and Humidity Targets
Leafy vegetables, berries, root vegetables, and tropical fruits do not behave the same way. Some lose water quickly. Others suffer chilling injury. Each room should follow the product’s real storage needs rather than one temperature setting used across the whole plant.
Coordinated Precooling, Storage, and Freezing Capacity
Peak intake often matters more than average daily volume. The precooling system, storage rooms, and freezing line should handle the same production rhythm. Otherwise, warm produce queues in front of one section while expensive equipment sits idle in another.
Harvest-to-Storage Precooling Strategy
Precooling removes field heat before it becomes a larger storage load. This stage is often rushed during budget planning, yet it has a direct effect on appearance, weight loss, and shelf life. Fast cooling is useful, but rough cooling is not. The method still has to suit the product.
DISU 0°C Ice Slurry Precooling
The DISU ice slurry machine produces a mixture that holds the cooling medium near 0°C. Its 0°C ice slurry precooling can quickly remove respiration heat after harvest while limiting the risk of freezing damage. The official solution includes immersion-style treatment for suitable produce.
Low-Temperature High-Humidity Precooling
Products that should not be immersed can use a low-temperature, high-humidity route. The higher humidity helps reduce moisture loss while cold air removes heat. Air velocity and crate arrangement still need checking, because blocked passages cause uneven cooling.
Produce-Specific Precooling Method Selection
Choose the method after reviewing skin strength, packaging, contamination risk, water tolerance, incoming temperature, and required cooling time. A soft berry and a boxed root vegetable may pass through the same factory, but they should not automatically use the same precooling process.
Controlled Atmosphere Storage Architecture
After precooling, the storage room has to slow respiration without harming the produce. Temperature is only one control point. Humidity, gas composition, airflow, loading density, and door activity all change the result. A warehouse can look fine on a drawing and still become awkward to run.
Temperature and Relative Humidity Control
Stable room temperature reduces repeated compressor cycling and product stress. Humidity should be high enough to limit weight loss but not so high that condensation becomes normal. Coil selection, air distribution, defrost timing, and door management all play a part.
Oxygen, Carbon Dioxide, and Ethylene Management
A Almacén de atmósfera controlada manages oxygen, carbon dioxide, and ethylene along with temperature and humidity. Lower respiration and slower metabolism can extend the useful storage period, especially for produce held beyond short-term distribution.
Warehouse Zoning and Airflow Distribution
Separate rooms or zones are usually better than forcing unrelated products into one condition. Air must pass through the load, not only around it. Pallet spacing, stacking height, packaging openings, and evaporator position deserve attention before construction starts.
One overseas project used an 8,000-ton fruit and vegetable cold storage design within a 20,000 m² storage and processing center. It handled several produce types rather than one crop alone. This kind of fruit and vegetable processing case experience shows why zoning and product flow are part of refrigeration design, not a later warehouse issue.
Quick-Freezing and Refrigeration System Integration
Not every product will leave fresh. Diced fruit, cut vegetables, peas, peppers, carrots, broccoli, and similar products may need individual quick freezing after preparation. The freezer, refrigeration source, conveyor loading, and upstream washing line must work at the same speed.
Two-Stage Fluidized IQF Freezing
El two-stage Fluidized IQF Technology first cools the product surface to its freezing point. Mechanical movement helps keep pieces apart. The second stage completes deep freezing and brings the product temperature to −18°C or lower.
CO₂ Refrigeration System Matching
A CO₂ refrigeration system can be paired with the Fluidized Individual Quick Freezer. The design still depends on production volume, entering temperature, local ambient conditions, defrost demand, and daily running hours. The refrigerant choice alone does not decide performance.
Product Separation and Core Temperature Control
Good fluidization needs reasonably even product size and loading depth. Too much product on the belt reduces movement and creates clumps. Operators should check core temperature, not only room air or belt exit readings. That small habit catches many quality problems early.
Plantwide Control and Lifecycle Planning
A fruit and vegetable plant rarely runs at one fixed load. Harvest peaks, crop changes, cleaning periods, door openings, and storage turnover all move the cooling demand. Controls should follow these changes without making the system difficult for operators to use.
Refrigeration Load and Part-Load Management
Select compressor capacity around real load profiles. The screw compressor knowledge base includes capacity regulation from 10% to 100%, PID load adjustment, operating data storage, alarm records, and remote communication support. These functions are useful when several rooms and process lines run at different times.
Defrost, Monitoring, and Energy Control
Defrost should clear frost without adding unnecessary heat to the room. Temperature trends, suction pressure, door activity, and alarm history help staff spot trouble before product quality moves outside its target. Fancy screens are less important than clear, usable data.
Maintenance Access and Future Capacity Expansion
Leave space around coils, compressors, valves, filters, and control cabinets. Pipe routes should allow later inspection and extension. Future expansion is cheaper when spare connections, electrical allowance, and control points are planned before the first production season.
Build a Reliable Fruit and Vegetable Processing Line with Full-Service Support
A complete project needs more than a refrigeration quotation. Early process review, civil layout, utility data, equipment matching, installation planning, and staff training reduce the chance of late changes. Those changes are usually expensive, and everyone knows they tend to appear when the site is already crowded.
Full-Process Consulting and System Design
A través de consulta de proceso completo, you can review market needs, feasibility, plant planning, preliminary design, construction drawings, budgets, equipment installation, and refrigeration contracting in one project route.
Whole-Industry-Chain Equipment Integration
Whole-industry-chain coordination connects processing flow, cold rooms, quick-freezing equipment, refrigeration machinery, controls, and building services. This reduces the common problem of buying several good machines that do not work well together.
Installation, Commissioning, and Lifecycle Service
The available lifecycle service support covers installation, commissioning, training, maintenance, system diagnosis, and upgrades. Before requesting a proposal, prepare crop types, hourly intake, entering temperature, target temperature, storage time, room capacity, local climate, power supply, and expansion plans. A technical project discussion can then begin with useful data instead of rough guesses.
