Technical characterictic of the present invention also is: described sterilization material effuser, thermal material flow to pipe and inlet feed flows to pipe and all adopts the U-shaped coil pipe, and the sterilization material flows out pipe box and is contained in the inside that inlet feed flows to pipe.
Another technical characterictic of the present invention is: described inlet feed flows to pipe and flows to the pipe that pipe adopts identical caliber with thermal material.
The cryogenic sterile filling process of a kind of plastic bottle beverage provided by the invention is characterized in that this technology comprises the steps:
1) tea or fruit juice raw material and auxiliary material and the pure water drunk are placed material-compound tank by desired proportioning, stir, form the can material;
2) utilize high pressure pump that the can material is sent in the instantaneous heat sterilization device of adverse current, material enters the thermal material that inlet feed in the countercurrent heat exchange pipeline flows in pipe 4 and the instantaneous heat sterilization device of adverse current successively and flows to pipe 8, in thermal material flows to pipe 8 in the process of flowing by the heating arrangement heat sterilization, the heat sterilization temperature is 150~155 ℃, and the heat sterilization time is 8~12 seconds;
3) the can material after the sterilization flows into the sterilization material effuser in the countercurrent heat exchange pipeline, the can material carries out interchange of heat with can material that inlet feed flows in the pipe in sterilization material effuser, the temperature out of sterilization back can material is 25~30 ℃, and the time of control can material from the normal temperature material inlet to the sterilization material outlet is 4~6 minutes;
4) the can material after sterilization enters hundred grades and purifies bottling department, plastic bottle behind the medicine cleaning and sterilizing is sent into hundred grades purify bottling department, adopting ozone content is that 0.8~1.2mg/L Ozone Water is dashed bottle, carries out can by dashing bottle, can and the Trinitarian bottle placer of spiral cover again.
The present invention compared with prior art, have the following advantages and the high-lighting effect: 1. owing to adopted the countercurrent flow structure and the technology of cold and hot material, homogeneous heating not only, and thermal loss is little, greatly reduces the consumption of the energy, 2. adopts the instantaneous type of heating of adverse current, the effect that material can reach a high temperature in flow process and sterilize, time of heat is short, has avoided the high-temperature oxidation of beverage, is damaged because of long-time heating makes the nutriment in the beverage thereby effectively overcome in the prior art.3. adopt the normal temperature can, because the can temperature is low, effectively overcome because of high-temperature filling caused " ripe soup flavor ", kept the genuineness of tea, fruit juice, not only mouthfeel is good, and the loss of the nutrition of finished product is little.4. adopt conventional PET bottle and normal pressure lid to replace heat-resisting, pressure-proof PET Bottle and closure, reduced cost of product.5. device structure is simple, and is stable, and is convenient to safeguard.
