Abstract

The invention discloses a cooked food vacuum cooling device with adjustable vacuum degree, which comprises a PLC controller, a vacuum chamber, a pressure sensor, a water ring pump, a circulating water pump, a temperature sensor, a heat exchanger and a frequency conversion fan. The invention cools the working water temperature of the water ring pump through the heat exchanger, so that the working water can be recycled, and at the same time, the heat exchange heat of the heat exchanger can be adjusted by adjusting the fan speed to adjust the working water temperature, and finally achieve the goal of controlling the vacuum degree of the vacuum chamber. Purpose.

Description

technical field [0001] The invention relates to the technical field of vacuum cooling, in particular to a vacuum cooling device for cooked food with adjustable vacuum degree. Background technique [0002] The principle of vacuum cooling is to use the low-pressure environment caused by vacuum to evaporate the moisture inside the product, and the temperature of the product itself will drop due to the heat absorbed by evaporation. In the 1990s, people all over the world paid more and more attention to food safety issues, and the international food industry began to study the application of vacuum cooling technology in the food industry. The Irish Food Safety Advisory Committee stipulates that large pieces of cooked meat must be cooled from 74°C to 4°C within 2.5 hours, and some other European countries have also formulated similar processing standards. Generally, it takes a long time to cool the product through traditional methods such as air cooling and water cooling, which t...
