Supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizing device

Abstract

The invention provides a supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizing device. The supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizingdevice comprises a supercritical carbon dioxide generating device, a sterilizing kettle, an air duct, and a driving mechanism, wherein the supercritical carbon dioxide generating device is connectedwith the sterilizing kettle through the air duct; the driving mechanism comprises a driving motor, a transmission shaft sleeve, a main transmission shaft and secondary transmission rods; the transmission shaft sleeve is integrally connected with the secondary transmission rods; an air inlet pipe is arranged at the upper end of the transmission shaft sleeve; air outlet pipes are symmetrically connected to the lower end of the transmission shaft sleeve; a first mixing mechanism is connected to the bottom of the main transmission shaft; and second mixing mechanisms are arranged at the tail ends of the secondary transmission rods. According to the supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizing device disclosed by the invention, the nutrient components in fruit and vegetable juice can be effectively kept, and besides, nutrient substances of the fruit and vegetable juice are further released; components in the fruit and vegetable juice can be sufficiently in contact with supercritical carbon dioxide, so that a good sterilizing effect is achieved; and the supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizing device is especially suitable for sterilization of high-viscosity fruit and vegetable juice products.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a supercritical carbon dioxide high-viscosity fruit and vegetable juice sterilizing device. Background technique [0002] Fruit and vegetable pulp beverage is a new type of beverage after fruit juice beverage, carbonated beverage and lactic acid bacteria beverage. It concentrates the essence of fresh fruits and vegetables and integrates nutrition, physiology and health care. Our country is rich in fruit and vegetable resources, with large output and strong seasonality. The industrialized production of fruit and vegetable beverages is to preserve the nutrients of fruits and vegetables to the maximum extent after processing through unique production technology, improve the edible value, and make the color, aroma and taste of the products , The tissue form is good, can be stored for a long time, and can be used at any time. [0003] A good fruit and vegetable beverage sho...

Problems solved by technology

For this reason, non-thermal sterilization technology is the first choice for sterilizing fruit and vegetable juices and improving their shelf life. However, the ultra-high pressure equipment of current non-thermal sterilization technology is easy to destroy the cell structure in the pulp and denature the nutrients, which affects the nutritional value of fruit and vegetable juices. There is a need for a new sterilization device, especially suitable for high-viscosity fruit and vegetable juices, which can further release the nutrients of fruit and vegetable juices while ensuring the sterilization effect
