Description

Vacuum drier for high-temperature cooking food

Technical Field

The utility model relates to a vacuum drier for high-temperature cooking food.

Background

The boiling point of water decreases with decreasing gas pressure. The high-temperature steamed food just taken out of the pot is directly put into a vacuum environment, and high-temperature liquid water contained in the food is vaporized and separated out more quickly. Vacuum drying can prolong shelf life of food, prevent food oxidation, and maintain nutritional components. The water vapor entering the vacuum pump will damage the air extraction capability of the vacuum pump, and the vacuum dryer is provided with a condenser for separating the water vapor in the vacuum pipeline. When the mixed gas containing water vapor in the drying chamber meets the condenser in the vacuum pipeline, the water vapor is cooled and turned into ice frost to be attached to the cold head of the condenser, and the air without water vapor continuously moves forward in the vacuum pipeline to enter the vacuum pump and is further discharged out of the vacuum system by the vacuum pump. The frost attached to the cold head of the condenser can isolate the cold head from the contact with the water vapor, and the gas-water separation capacity of the condenser is reduced. The high-temperature steamed food has large water content, and the phenomenon that the vacuum degree cannot be pumped up and the water content of the dried food exceeds the standard can occur by using two continuous working cycles of the existing vacuum drying machine.
