Broccoli vegetable vacuum pre cooler is a device used to quickly reduce the moisture temperature of fresh vegetables and extend their shelf life. The specific introduction is as follows:
1. Machine structure:A vacuum precooler typically consists of a vacuum system, a cooling system, and a control system. The vacuum system includes vacuum pumps, vacuum pipelines, and vacuum valves, which are used to extract air and reduce environmental pressure. The cooling system includes cooling towers, cooling pipes, and coolers, which are used to circulate low-temperature cooling medium through pipes to lower the temperature of vegetables. The control system includes temperature controller, time controller, and vacuum degree controller, which are used to control the parameters and time of the entire pre cooling process.
2. Working principle:The working principle of a vacuum pre cooler is to extract air in a closed space, reduce environmental pressure, and rapidly evaporate the moisture on the surface of vegetables, thereby achieving the goal of rapid cooling. During the pre cooling process, vegetables will transfer heat to the cooling medium through the heat transfer effect of the cooling medium, gradually reducing the temperature of the vegetables. Ultimately, the vegetables will be cooled to the desired temperature before being packaged and stored.
3. Application scope:Vacuum pre cooling machines are widely used for pre cooling various fresh vegetables, fruits, meats, seafood and other foods. By processing with a vacuum pre cooler, the shelf life of food can be effectively extended, the quality and taste of food can be improved, and food loss can be reduced.
Advantages: Compared with traditional cooling methods, vacuum precoolers have the following advantages:
(1) Fast pre cooling speed:A vacuum pre cooler can quickly lower the temperature of vegetables to the desired level, greatly reducing the pre cooling time and improving production efficiency.
(2) Maintain vegetable quality:Vacuum pre cooling machine can perform pre cooling treatment in low-temperature environment, effectively maintaining the quality and taste of vegetables, and reducing the loss of vegetables during the pre cooling process.
(3) Energy conservation and environmental protection:The working principle of a vacuum precooler is to reduce environmental pressure by extracting air, without consuming a large amount of energy, and has the characteristics of energy conservation and environmental protection.
(4) High degree of automation:The vacuum pre cooling machine can achieve automated control by controlling the parameters and time of the entire pre cooling process through temperature controllers, time controllers, and vacuum degree controllers, thereby improving production efficiency and quality.
function
The broccoli vegetable vacuum pre cooler can achieve the following functions:
1. Lowering vegetable temperature: By using a vacuum environment and low-temperature water, the temperature of vegetables can be quickly lowered, effectively maintaining their freshness and taste.
2. Reduce water evaporation: A vacuum environment can reduce water evaporation in the air, thereby avoiding vegetables from becoming dry due to excessive water loss.
3. Preventing browning: A vacuum pre cooler can reduce the presence of oxygen, thereby preventing vegetables from browning due to oxidation and maintaining their color and freshness.
4. Improving packaging quality: Through vacuum pre cooling treatment, the temperature and humidity of vegetables can be effectively controlled, thereby improving packaging quality and extending the shelf life of vegetables.
