Rice vacuum pre cooler is a machine used for rice preservation. By placing rice in a vacuum environment, the ambient temperature and gas concentration are reduced, thereby extending the shelf life of rice. The specific introduction is as follows:
Working Principle
The working principle of the rice vacuum pre cooler is to use vacuum to reduce the ambient temperature. Firstly, put the rice into the pre cooling chamber, and then use a vacuum pump to extract the air inside the pre cooling chamber, reducing the air pressure and the ambient temperature. This can effectively lower the temperature of rice, thereby extending its shelf life.
Application Areas
Rice vacuum pre cooler is mainly used in the catering industry and food processing industry, for preserving food such as rice and rice products.
Characteristics
The rice vacuum pre cooler has the following characteristics:
① High efficiency: The rice vacuum pre cooler can quickly reduce the temperature of rice, thereby improving the preservation efficiency.
② Maintain original quality: The rice vacuum pre cooler can maintain the original quality of rice, including taste, color, nutritional content, etc., keeping the rice fresh during the shelf life.
③ Energy saving and environmental protection: The working principle of the rice vacuum pre cooler is to use vacuum to reduce the ambient temperature, which does not require a large amount of energy consumption and does not produce pollution, and has the characteristics of energy saving and environmental protection.
④ High degree of automation: The rice vacuum pre cooler can achieve automated operations, including automatic weighing, automatic loading and unloading, automatic control, etc., improving work efficiency and production efficiency.
Category
There are two main types of rice vacuum pre coolers: plate vacuum pre coolers and tube vacuum pre coolers.
1. Plate type vacuum precooler: This type of vacuum precooler uses a plate heat exchanger as the cooler, which can achieve rapid cooling and efficient heat transfer. Usually used for pre cooling and preservation of food such as rice and noodles.
2. Tube type vacuum precooler: This type of vacuum precooler uses a tube heat exchanger as the cooler, which can achieve a high degree of vacuum and high heat transfer efficiency. Usually used for pre cooling and preservation of vegetables, fruits, and other foods.
The above are the two main types of rice vacuum pre cooling machines, and the specific selection needs to be determined according to actual needs and application scenarios.
