Product Overview
The CVF-1000W-2P is a medium-capacity fruit and vegetable vegetable vacuum cooler designed for rapid, uniform post-harvest cooling. Using a water-cooled shell-and-tube condenser, it maintains stable condensing temperatures of 38~42°C for optimal energy efficiency. Each batch cycles 800~1000kg of produce from ambient field temperature down to 0~10°C in just 15~30 minutes, with water loss kept under 2%.
The unit accommodates 2 standard pallets (trolleys) matching common crate and tote dimensions, making it easy to integrate into existing harvesting and packaging workflows.

FAQ
Q: What is the daily throughput of this machine?
A: With 30-minute cycles (including loading/unloading) over an 8-hour shift, daily capacity reaches 12~16 tons, approximately 4,000~5,000 crates of leafy vegetables.
Q: What site conditions are needed for water-cooled models?
A: A cooling water system (cooling tower + water pump) is required with a circulation rate of approximately 3~5 m³/h. Stable tap or recirculated water supply is recommended.
Q: Can pre-packed crates be processed directly?
A: Yes. The 2-pallet design accommodates standard crates (600×400mm). Produce can be loaded directly into the chamber without repacking.
