Purchase of a Vacuum Cooling Machine
For purchasing a vacuum cooling device for agricultural products (such as vegetables, fruits, flowers, and fresh plants), you need to pay attention to specific technical and practical considerations to ensure the device can optimally cool and dehumidify the products while preserving their quality. Below, we review the most important points:
1. Device Compatibility with Agricultural Product Type
- Lightweight products (e.g., leafy greens, strawberries, mushrooms) require high cooling speeds to prevent wilting.
- محصولات سنگین (مانند هندوانه، سیب، هویج) به خلأ قویتر و زمان بیشتری نیاز دارند.
- Flowers and ornamental plants require controlled temperature and proper humidity to avoid withering.
2. Capacity and Dimensions of the Device
- Vacuum chamber capacity: Should match your harvest volume (e.g., 100 kg per batch or more).
- Chamber size: Must provide enough space for bulky products (e.g., lettuce or cabbage) to avoid compression.
3. Cooling Parameters
- Temperature reduction speed: The device should lower product temperature from 30°C to 4°C within 20–30 minutes.
- Minimum achievable temperature: Some products require temperatures close to 0°C.
- Required vacuum level: Typically 1 mbar, depending on the product.
4. Material and Build Quality
- Stainless steel (Grade 70): Adequate thickness to withstand vacuum pressure.
- Strong sealing system: Must prevent air leaks for effective vacuum creation.
- Powerful vacuum pump: Should maintain stable vacuum without fluctuations.
5. Control and Automation
- Smart control panel: Automatically adjusts temperature, pressure, and cooling time.
- Alert system: Warns in case of leaks or pump failure.
- Data logging (datalogger): Monitors the process and ensures quality control.
6. Energy Efficiency and Performance
- Power consumption (three-phase): Larger devices typically require three-phase power.
- Humidity recovery system: Some devices recover extracted moisture, improving water efficiency.
7. Cleanability and Hygiene
- No dead corners in design: Ensures easy cleaning and prevents contamination.
- Hygiene certifications (e.g., FDA, CE, ISO 22000): Especially important if products are for export.
8. After-Sales Service and Warranty
- Device warranty (usually 1–2 years)..
- Availability of spare parts and service centers in Iran..
- 9. 9. Practical Testing Before Purchase
- Request a demo (testing the device with actual products)..
- Visit production lines of other farmers or companies using this device..
Final Summary for Purchasing a Vacuum Cooling Device
- Sensitive products (e.g., leafy greens) require devices with high cooling speeds.
- Device capacity should align with your daily production volume.
- Smart control systems and energy efficiency help reduce operational costs.
- After-sales service is crucial, especially in Iran.
