Description
Technical field
The invention belongs to food machinery field, relate to a kind of beverage sterilizing device.
Technical background
Non-thermal sterilization technology refers to that the method for employing non-heated kills the harmful and pathogenic microorganism in sterilization object (material, goods or environment), makes sterilization object reach the sterilization technology of specific sterility requirement.It is relatively slow and produce the weakness such as hot injury to sterilization object that non-thermal sterilization technology overcomes general thermally-sterilized heat transfer, is suitable for the sterilization of the material of particular thermal sensitivity, goods and environment.In sterilization process, food temperature does not raise or raises very low, has both been conducive to the physiologically active keeping functional component in food, is conducive to again keeping color and nutritional labeling.
Current physics non-thermal sterilization mainly contains irradiation, ultraviolet, impulse electric field, oscillating magnetic field, ultrasound wave, pulsed light, pulse x rays etc., the main at present 254nm of the employing ultraviolet of ultraviolet germicidal lamp is by irradiation microbial destruction and the DNA(DNA (deoxyribonucleic acid) changing microorganism) structure, make antibacterial dead or irreproducible offspring at once, reach the object of sterilization.But this ultraviolet sterilization is not strong owing to there is penetration capacity, and need action time of a specified duration, the problems such as existence effect dead angle fail to be used widely.The ultraviolet of another kind of 185nm can by the O in air
2become O
3(ozone), ozone has strong oxidation, can kill bacteria effectively, the dispersivity of ozone just can make up due to ultraviolet only linearly propagate, the shortcoming at dead angle of sterilizing.Also do not find two kinds of ultraviolet to combine the technical equipment carrying out sterilizing at present.
Summary of the invention
The object of the present invention is to provide a kind of ultraviolet single-action falling film type bactericidal unit.This device may be used for beverage, particularly contains in the disinfecting action of the functional drinks of temperature-sensitive or active substance.
The present invention is achieved by the following technical solutions.
Ultraviolet single-action falling film type bactericidal unit of the present invention comprises liquid inlet (1), nozzle (2), dispersion section (3), distribution plate (4), ultraviolet lamp tube (5), gap adjustment ring (6), adjustable ring joystick (7), fluorescent tube pallet (8), liquid outlet (9), jet chimney (10).
Liquid inlet (1) is positioned at the top of device, be connected with nozzle (2), then distribution plate (4) is connected to through dispersion section (3), distribution plate (4) is uniform-distribution with the groove that bore is a bit larger tham ultraviolet lamp tube (5) external diameter, there is gap adjustment ring (6) lower end of groove, gap adjustment ring (6) is connected with the joystick be arranged on outside device (7), ultraviolet lamp tube (5) is placed on through groove and gap adjustment ring (6) and is located on the fluorescent tube pallet (8) of lower end, fluorescent tube pallet (8) below liquid outlet (9), outlet side is connected with jet chimney (10), and become 90 degree with liquid outlet (9).
Ultraviolet lamp tube of the present invention (5) comprises the ultraviolet lamp tube sending out 254nm and the ultraviolet lamp tube sending out 185nm.
Ultraviolet lamp tube of the present invention (5) adopts the arrangement of (as shown in Figure 2) alternating pattern, the length of the distance > ultraviolet lamp tube between distribution plate (4) groove lower end and fluorescent tube pallet (8).
Technique effect of the present invention is: adopt thin film distribution technique, controls liquid material thickness, reduces the shortcoming of ultraviolet penetration capacity deficiency.And due to liquid shape thin layer, the required ultraviolet irradiation time shortens greatly.Another by the ingenious collocation of ultraviolet lamp tube of transmitting two kinds of wavelength, 254nm ultraviolet eliminates sterilization dead angle in conjunction with 185nm ultraviolet, effectively kills the antibacterial in beverage.
