Abstract

The invention discloses a high-permeability airflow puffing device and method for fruits and vegetables, which comprises a horizontal cylindrical puffing tank, a high-permeability gas storage tank, a vacuum pump, an air storage tank I, an air storage tank II and an air compressor connected in order through pipelines. Machine, the gas storage tank I is provided with an air bag I, and the gas storage tank II is provided with an air bag II. The fruit and vegetable high-permeability airflow puffing device of the present invention reduces the fruit and vegetable puffing temperature, reduces nutrient loss, high-permeability gas can be recycled, part of the pressure energy is recovered, heat energy loss and production cost are reduced, and production efficiency and product quality are improved.

Description

Technical field [0001] The invention belongs to the technical field of puffed food processing, and specifically relates to a high-permeability air-flow expansion device for fruits and vegetables. The invention also relates to a method for high-permeability air-flow expansion of fruits and vegetables using the device. Background technique [0002] At present, the processing technology of fruit and vegetable puffed products mainly uses heating to produce superheated water inside the fruit and vegetable raw materials, and then suddenly releases the pressure, and uses the pressure difference generated by flash evaporation of the superheated water inside the raw materials to achieve fruit and vegetable puffing, and then cools and sets in a vacuum state. This method needs to heat the raw materials to about 100 degrees, which will damage the nutrients greatly, and the equipment used has poor vacuum heat transfer ability, which makes the production cycle longer, the equipment output is lo...
