Abstract
The utility model discloses a spiral flow heat exchange tube of a liquid food material sterilizer, which belongs to the technical field of indirect sterilization of liquid food materials and aims to overcome the shortcoming that the turbulence degree is not intense enough when a liquid material flows in a heat exchange tube in the existing tubular sterilization equipment. The spiral flow heat exchange tube comprises the heat exchange tube, wherein a central tube with two closed ends is axially arranged in the center of the heat exchange tube; continuous spiral flow guiding vanes are arranged between the outer wall of the central tube and the inner wall of the heat exchange tube; the inner sides of the flow guiding vanes are fixedly connected with the outer wall of the central tube, and the outer sides of the flow guiding vanes are in contact with the inner wall of the heat exchange tube. The spiral flow heat exchange tube disclosed by the utility model is applicable to tubular food sterilization equipment.
Description
Technical field
The utility model relates to a kind of food liquid material indirect type sterilization technology, particularly relates to a kind of spiral flow heat exchanger tube of food liquid material sterilization machine.
Background technology
In food processing enterprises, there are a lot of food liquids need in Raw material processing process, carry out sterilization processing, and require aseptic packaging after sterilization, as dairy products, fruit juice, tomato ketchup, soya-bean milk, soy sauce, ice cream, ice-cream stick slurry etc.In order to guarantee sterilization fully and completely, can protect again nutritional labeling and local flavor, adopt high temperature, short time or ultra high temperature short time sterilization mode more.Carry out the object of high temperature, short time or ultra high temperature short time sterilization in order to realize liquid towards food material, most popular at present domestic food processing factory is tubular type disinfection equipment.The basic structure of tubular type disinfection equipment is, in housing, heat-exchanging tube bundle is housed, and between housing and heat-exchanging tube bundle, is connected with tube sheet.Tubular type disinfection equipment is in the time carrying out sterilization operation, the liquid material that need to carry out sterilization processing flows in heat exchanger tube, the heating agent (being generally steam) of HTHP passes into behind the space of housing, heat heats liquid material mobile in managing through the outer wall of heat exchanger tube, and liquid material reaches the required temperature of sterilization and after the retention time, becomes product to discharge.In high temperature process, the liquid material in pipe will reach temperature and approach 100 ℃, and the temperature of the outer heating agent of pipe will be higher than 100 ℃; And in ultra high temperature short time sterilization process, the liquid material in pipe will reach temperature more than 120 ℃, the temperature of the outer heating agent of pipe is higher than 120 ℃.In the pipe of the heat exchanger tube of current tubular type disinfection equipment, it is smooth through hole, the turbulent extent of liquid material stream is strong not, make liquid material stream there will be flow velocity inconsistent in the part of tube hub with the part of pressing close to inside pipe wall, programming rate has the phenomenon of speed, in order to reach the uniformity of liquid material heating, can only extend the heat time to liquid material, like this, can cause the loss of nutrition and the destruction of local flavor to the material of some thermal sensitivity, simultaneously, the liquid material larger for some viscosity also can form coking film at the inner surface of heat exchanger tube, not only having a strong impact on product quality returns the cleaning sanitary work of heat exchanger tube and brings difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of spiral flow heat exchanger tube of food liquid material sterilization machine, turbulent extent strong not deficiency when overcoming the current existing liquid material of tubular type disinfection equipment and flowing in heat exchanger tube.
The utility model is achieved by following technical proposals.
The utility model comprises heat exchanger tube, at the center of described heat exchanger tube, be axially arranged with the central tube of closed at both ends, between the outer wall of described central tube and the inwall of described heat exchanger tube, be provided with continuous spiral Air deflector, the inner edge of described Air deflector and the inwall that the outer wall of described central tube is fixedly connected, described heat exchanger tube is touched in its outside.At food-processing industry, described heat exchanger tube is the very high parts of employing rate in all kinds of different plant equipment, as heat exchanger tube as described in all will using at equipment such as dry, concentrated, freezing, molten ice.In the utility model, be using described heat exchanger tube as prior art, but improve; When having installed in described heat exchanger tube after described Air deflector, the liquid material that enters described heat exchanger tube is just forced the change of travel direction by described Air deflector, liquid stream will inevitably cause turbulent extent aggravation constantly changing in nyctitropic process, the programming rate of liquid material is accelerated, and the intensification at each position is even, even the liquid material that some viscosity are larger, due to the reinforcement of turbulent extent, also can reach quick heating and the even and difficult coking film that forms.The effect of described central tube is the supporting to described Air deflector, makes described Air deflector become an entirety with rigidity, in the time of work, can better play a role, and meanwhile, is convenient to dismounting.
In general, the liquid stream that enters described heat exchanger tube in order to allow is divided into several strands of threads, described Air deflector can axially be set up in parallel multiple, but consider, especially the described heat exchange tube diameter of food liquid disinfection equipment can be very not thick for food processing equipment, so institute's Air deflector is axially set up in parallel three by the utility model.Simultaneously, outer edge at described Air deflector is equipped with welt, inwall, its one end and described Air deflector that the outside of described welt is closely attached on described heat exchanger tube are fixedly connected, owing to having set up described welt between described Air deflector and the inwall of described heat exchanger tube, strengthen contact area, can there is more heat to conduct to described Air deflector, make described Air deflector when liquid conductance is drawn, also play heat effect.
Against existing technologies, the beneficial effects of the utility model are:
The turbulent extent of having strengthened significantly liquid material stream in described heat exchanger tube, heats up liquid material more even sooner, also there will not be the phenomenon of coking film, is conducive to improve sterilization quality, is convenient to the cleaning of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, the A-A cut-away view that Fig. 2 is Fig. 1.In figure: 1, heat exchanger tube, 2, central tube, 3, Air deflector, 4, welt.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
Convenience in order to manufacture in the time that the utility model is implemented, the caliber of heat exchanger tube should suitably amplify, and central tube 2 is selected stainless steel seamless pipe, and Air deflector 3 and welt 4 are all selected stainless sheet steel, and connecting mode should adopt welding; When enforcement, first Air deflector 3 is welded on central tube 2, then welt 4 is welded on Air deflector 3, the core body of then former three being made packs in heat exchanger tube 1; This core body can rotate along the hand of spiral of Air deflector 3 by limit rim in the time packing into, otherwise in the time that needs draw off this core body, can counter-rotate while pulling out.The utility model is all implemented on straight length, as the series winding back and forth that will carry out branched straight tube connects, is communicated with " U " shape light pipe at two ends.
