Technical field
The utility model relates to the disinfection equipment in a kind of food processing, relates in particular to a kind of equipment that adopts high voltage electric field to carry out sterilization.
Background technology
In food processing process, using disinfection equipment to carry out sterilization to food is one of very important link, is the core technology of food industry, its objective is kill microorganisms, and passivation enzyme, ensures food safety and make food have enough shelf-lifves.Conventionally the thermization device adopting in food industry at present carries out sterilization to food, although thermal sterilization can ensure the safety of food aspect microorganism, but in the time of heat treatment, heat energy penetrates food and arrives the core Slow cooling again subsequently of food, this process can be destroyed nutritional labeling and the natural characteristic in food to some extent, such as the loss of local flavor change, quality deliquescing, color and luster variation and vitamin.Except having above-mentioned variation, also easily cause that protein denaturation, amino acid destroy, and destruction to heat sensitive other nutritional labeling.
In order to keep to greatest extent the built-in quality of food itself, a class novel food sterilizing technology---cold sterilization technology arises at the historic moment.Cold sterilization refers in sterilization process food temperature do not raise or raise very low a kind of safety, efficient sterilizing method, as super-pressure (High Hydrostatic Pressure, HHP) sterilization, high-pressure pulse electric (Pulsed Electric Fields, PEF) sterilization, pulse strong-light sterilization, ultraviolet-sterilization, radiation sterilization etc.Cold sterilization can not only ensure the safety of food aspect microorganism, and can keep preferably intrinsic nutritional labeling, matter structure, color and luster and the freshness of food and the physiologically active of food function composition.In recent years, along with the change of health of people nutrition idea, genuine food becomes fashion gradually, thereby cold sterilization technology is subject to the great attention of food industry.
Electric-field sterilizing tech is one of focus of world's cold sterilization technology research and development in recent years.Particularly high-pressure pulse electric sterilization PEF technology, has obtained studying more fully, but because its disinfection system complexity, cost are high, has restricted its application in food industry.
Utility model content
The utility model object is to provide a kind of technology high voltage electric field disinfection equipment simple, with low cost for deficiency of the prior art, can, in killing pathogen, extending effective period of food quality, keep to greatest extent the built-in quality of food itself.
For achieving the above object, the utility model provides a kind of high voltage electric field disinfection equipment, comprise pipeline, process chamber and high voltage source, process chamber is arranged in the middle of pipeline, wherein said process chamber is made up of reactor, pressure regulator and heat exchanger, described reactor is made up of two electrodes that are connected with high voltage source respectively and insulation barrier, insulation barrier sealed attachment is in pipeline the inside and between two electrodes, insulation barrier centre is provided with the aperture with described pipeline formation processing chamber, processed fluid Continuous Flow small holes.
Above-mentioned high voltage electric field disinfection equipment, wherein said two electrodes connect with line seal, form hollow circular-tube; The thickness of described insulation barrier is 0.5-10mm; Hole diameter in the middle of described insulation barrier is 0.5-10mm; Described reactor serial or parallel connection in pipeline uses.
High voltage electric field disinfection equipment of the present utility model uses high voltage electric field sterilizing mechanisms, and its treatment chamber designs and electrode configuration, make high-tension electricity concentrate on some regions, and form high field in this region, thereby reach sterilization object.High voltage electric field sterilization technology is identical with high voltage pulsation electric-field sterilizing tech principle, but implementation is simpler, economical.High voltage electric field disinfection equipment is mainly used in fruit juice, tea beverage, bottled water, beer, milk and milk beverage, liquid egg, fermented product, flavouring, zymotic fluid, oral liquid, liquid medicine, biological cleaning fluid and other sterilization to thermo-responsive fluid product, can, in killing pathogen, extending effective period of food quality, keep to greatest extent taste, color and the nutrient content unchanged of food itself.

Detailed description of the invention
To describe specific embodiment of the utility model below in detail.It should be noted that the embodiments described herein, only for illustrating, is not limited to the utility model.
As shown in Figure 1, the utility model provides a kind of high voltage electric field disinfection equipment, comprise pipeline 1, process chamber 2 and high voltage source, process chamber 2 is arranged in the middle of pipeline, wherein said process chamber 2 is made up of reactor, pressure regulator and heat exchanger, and wherein pressure regulator and heat exchanger all belong to prior art.
As shown in Figure 2, described reactor is made up of the electrode 3 being connected with high voltage source respectively and electrode 6 and insulation barrier 4, insulation barrier 4 sealed attachment are in pipeline 1 the inside and between two electrodes, insulation barrier 4 centres are provided with the aperture 5 with described pipeline formation processing chamber, processed fluid Continuous Flow small holes 5.Described two electrodes and pipeline 1 sealed attachment, form hollow circular-tube.The thickness of described insulation barrier 4 is 0.5-10mm, and aperture 5 diameters in the middle of insulation barrier are 0.5-10mm; Described reactor serial or parallel connection in pipeline uses.
Its technological process of production is: stock-high voltage electric field sterilization-energy recovery-product is filling.
High voltage electric field sterilization is the method that adopts the highfield of high voltage generation to carry out sterilization.Its basic process is to process at two interelectrode food by transient high voltage, and cell leakage is increased, and film-strength weakens, and telolemma is broken, material outflow in film, the outer material of film deeply, cell body death.Electromagnetic field produces ionization, has blocked normal biochemical reaction and the metabolism of cell membrane, and bacterium substance in vivo is changed.
