CVF-30A-L Food Vacuum Cooler — 30kg/Batch Rapid Cooling for Cooked Food

Vacuum cooling exploits the principle that water boils at a lower temperature under reduced pressure: surface moisture evaporates rapidly and carries heat out of the food. The CVF-30A-L brings 30kg of cooked food from 100°C to 2–8°C in 20–30 minutes inside a 0.28m³ chamber, with typical weight loss of 3–5%. It is an export-proven machine — the AUX customer in Russia runs it for daily cooked-food chilling.

Overview

The CVF-30A-L is a 30kg-class food vacuum cooler for cooked-food shops, small central kitchens, laboratories, and pilot trials. The chamber measures L700×W500×H800mm. The complete machine — mounting frame, vacuum chamber, vacuum pump, and refrigeration system — weighs about 1,500kg and runs on 3-phase 380V.

Three selling points:

1. High-temperature cooked food drops to chill temperature in 20–30 minutes, cutting pre-packaging wait from hours to half an hour
2. Copeland ZB45KQE compressor + Leybold SV100B vacuum pump — proven brands with reliable support
3. Air-cooled condenser — no cooling tower needed, simple installation

Product Advantages

1. Cooling Speed and Uniformity

Once 100°C cooked food enters the chamber, the vacuum makes surface water boil at low pressure; heat leaves with the vapor. The compact 0.28m³ space cools evenly, and the SV100B finishes the initial pull-down in about 1.1 minutes, so cooling dominates the cycle — 20–30 minutes to 2–8°C. That is roughly one-tenth of the time of natural air cooling (4–6 hours).

2. Vacuum System Match

The SV100B (≈100m³/h) pulls the 0.28m³ chamber to 600 Pa in about 1.1 minutes. The matched pump keeps pre-evacuation short relative to the cycle, so throughput stays high.

3. Structure and Build

The Q235 carbon-steel chamber has a rust-protected interior and food-contact surfaces treated to hygiene requirements. The 1,500kg machine is designed for hoisting and installation as a complete unit.

4. Flexible Configuration

Compressor, vacuum pump, and condenser can all be adjusted to budget and application, with cost-saving options from 15% to 35%. Both export and domestic configuration paths have been proven in the field.

FAQ

Q1: How much can the CVF-30A-L process per cycle? 30kg per batch. For cooked food entering at 90–100°C, it reaches 2–8°C in 20–30 minutes.

Q2: What is the weight loss? Will meat dry out? Typical weight loss is 3–5%, normal for vacuum cooling. For meat and cooked food, moisture loss is lower than natural cooling and texture is better preserved.

Q3: Is a cooling tower required? No. The CVF-30A-L ships with an air-cooled Kaidi condenser — connect power and run. It suits sites without cooling-tower conditions.

Q4: Can it pre-cool fruit and vegetables? The CVF-30A-L is a food cooler targeting cooked food and meat at 2–8°C. For produce, we have a dedicated vegetable vacuum pre-cooler line — tell us the material type when selecting.

Q5: What warranty and response time? Full-machine warranty 1 year; major components follow brand standards. For domestic customers, a solution is provided within 24 hours of a fault report.

Selection Guide

If your batch is around 30kg, the site has no cooling tower, and the budget is under CNY 100,000, the CVF-30A-L air-cooled version is the direct choice. If output will double later, skip ahead to a 50–100kg model to avoid a second investment. Tell us the material type, loading temperature, target final temperature, and batches per shift — we will size the configuration from your actual conditions.
