Vacuum variable-pressure buffering device for food processing

Abstract

The invention discloses a vacuum variable-pressure buffering device for food processing. The device is characterized by comprising a food processing tank, a vacuum pump and a vacuum buffering tank, wherein the food processing tank comprises a tank body and a close cover, to-be-processed food is arranged in the food processing tank, and a cavity is reserved between the to-be-processed food and the close cover; the vacuum buffering tank is a closed tank body and is communicated with the cavity of the food processing tank through a first gas pipeline and communicated with the vacuum pump through a second gas pipeline, the gas transmission paths of the first gas pipeline and the second gas pipeline in the vacuum buffering tank are provided with at least one layer of filter screen, and the bottom of the vacuum buffer tank is provided with a drain valve. The vacuum variable-pressure buffering device disclosed by the invention has the beneficial effect that the filter screen in the vacuum buffering tank is capable of removing the moisture, grease and other impurities entering along the air in vacuumizing so as to protect the vacuum pump and the second gas pipeline. In conclusion, the vacuum variable-pressure buffering device is simple in structure, easy to operate, low in cost and capable of realizing large-scale production.

Description

technical field [0001] The invention relates to the field of food processing, and mainly relates to a vacuum variable pressure buffer device for food processing. Background technique [0002] At present, in the process of food processing and production, many production processes will require the processed food to be flavored through processes such as masking and stewing. The traditional production process generally only relies on osmotic force to bring salt, spices and other substances into the food. This method is time-consuming and inefficient, and is not suitable for the trend of industrialized food production. With the application of vacuum variable pressure technology in food production, the efficiency of pickling and marinating processes has been greatly accelerated, and the pickling time has been shortened. However, most of the existing vacuuming equipment is concentrated in one device. The vacuum pump is mostly directly connected to the food processing tank. There i...

Problems solved by technology

However, most of the existing vacuuming equipment is concentrated in one device. The vacuum pump is mostly directly connected to the food processing tank. There is no pressure buffer when changing the vacuum degree. When the air is extracted from the food processing tank, it will contain water vapor and oil in the food. , residue or other impurities may enter the vacuum pump or the vacuum pipeline, reducing the vacuum efficiency and easily damaging the equipment
