Low temperature plasma-pulsed strong light sterilization reactor of freshly squeezed fruit and vegetable juice

Abstract

The invention provides a low temperature plasma-pulsed strong light sterilization reactor of freshly squeezed fruit and vegetable juice. The sterilization reactor includes a low temperature plasma reactor assembly, a pulsed strong light reactor assembly and a material conveying pipeline assembly; the plasma reactor assembly is provided with a positive plate and a negative plate, multiple emissionelectrodes are uniformly arrayed on the positive plate, and multiple holes are uniformly distributed in the positive and negative plates, so that the phenomenon of the turbulent flow, channel flow, wall flow and laminar flow of freshly squeezed fruit and vegetable juice in a low temperature plasma reactor can be avoided, and the freshly squeezed fruit and vegetable juice can be guaranteed to uniformly accept the action of low temperature plasma; multiple pulsed strong lights are uniformly arrayed at the periphery of the inner wall of a pulsed strong light reactor; and the material conveying pipeline assembly includes a material inlet, a material outlet, valves of the material inlet and the material outlet, a gas inlet, a gas outlet, valves of the gas inlet and the gas outlet and a duckbilled film distributor. Thus, the rapid and continuous sterilization of the freshly squeezed fruit and vegetable juice can be realized under normal temperatures and pressures; and the sterilization reactor is green and pollution-free in the whole process, energy-saving and environment-friendly, and has good economic benefits and promotion values.

Description

technical field [0001] The invention belongs to the field of non-thermal sterilization of food, and in particular relates to a continuous low-temperature plasma-pulse strong light sterilization reactor for freshly squeezed fruit and vegetable juices. Background technique [0002] Freshly squeezed fruit and vegetable juices are rich in nutrients and delicious in taste, and are favored by consumers. Freshly squeezed fruit and vegetable juices are heat-sensitive raw materials. The traditional thermal processing technology decomposes the aromatic substances and loses the natural flavor of natural fruits and vegetables, which has a great impact on the freshness and quality of freshly squeezed fruit and vegetable juices. How to maintain the original color, aroma, taste and functional components to the maximum extent during the processing of freshly squeezed fruit and vegetable juice is a current research hotspot and difficulty. Using non-thermal processing technology to process f...

Problems solved by technology

Most of these sterilization technologies are intermittent and single-mode sterilization. It is difficult to inactivate the vigorous bacterial spores and enzymes, and there is a safety risk of incomplete sterilization.
