Abstract
The utility model discloses a microwave heating liquid food sterilizing device, belongs to the technical field of liquid food sterilization and aims to overcome the defects that initial cost is high, treatment cost is high, cleaning work is troublesome and the like in the present liquid food sterilizing methods. The microwave heating liquid food sterilizing device comprises a feed pipe and a discharge pipe, and is provided with a heating pipe; the periphery of the heating pipe is provided with microwave generating units; two ends of the heating pipe are communicated with the feed pipe and the discharge pipe respectively; the microwave generating units are connected with a mains supply through power lines so as to be powered. The microwave heating liquid food sterilizing device is used for heating and sterilizing liquid foods.
Description
Technical field
The utility model relates to a kind of fluid food sterilization technology, particularly relates to a kind of fluid food sterilizing unit of heating using microwave.
Background technology
Because government payes attention to, and under the strictly regulating of relevant laws and regulations, process for sterilizing has become each food processing enterprises important step in process of production at present.The object of sterilization is kill pathogenic bacteria, spoilage organisms and other pathogenic microorganisms in raw-food material or semi-finished product and destroy enzymatic activity wherein, so that the Related product after processing can have certain storage life in the packing container of sealing; Require in sterilization process the nutritional labeling of retaining food product and local flavor as much as possible simultaneously.Along with the raising of people's living standard, the increase to food consumption convenience proposed requirement, fluid food increased popularity, wide in variety, the supply in market is increasing, as the soya-bean milk of packing, dairy products, fruit drink etc.Due to the peculiar character such as unsetting and volatile of fluid food, at present, the sterilization of food processing enterprises convection cell food normally adopts direct heating and two kinds of modes of indirect.Directly heating is with steam, directly to spray into food feed liquid or food feed liquid is injected into high thermal environment to carry out sterilization; Indirect is to allow the Surface Contact of food feed liquid and heat exchanger carry out heat exchange, thereby the temperature of raising food feed liquid reaches the object of sterilization.The pasteurization mode of above-mentioned convection cell food, higher to the configuration requirement of equipment, make initial cost expensive, as: purchase boiler and build special boiler room; As directly sprayed into food feed liquid with steam, to steam, should pass through special purified treatment, disposal cost meeting is very high; If adopt indirect mode, often local temperature is higher at the Surface Contact place of the heat exchanger plates of food feed liquid and heat exchanger or heat exchanger tube, be prone to very much the surperficial lamination being charred, not only waste raw-food material, affect local flavor, and increased larger trouble to cleaning.
Summary of the invention
The purpose of this utility model is to provide a kind of fluid food sterilizing unit of heating using microwave, overcomes the deficiencies such as the existing initial cost of the sterilization mode of current convection cell food is expensive, disposal cost is higher, cleaning trouble.
The utility model is achieved by following technical proposals.
The utility model comprises feed pipe, discharge nozzle, be provided with heating tube, in the outside of described heating tube, microwave generating unit is housed, the two ends of described heating tube are communicated with described feed pipe, discharge nozzle respectively, and the power supply of described microwave generating unit is connected by power line and civil power.In the technical program, for the ease of the shielding to microwave, described feed pipe, discharge nozzle should adopt metal material.The heat of described heating tube, from described microwave generating unit, that is to say, the microwave that described microwave generating unit produces is completely towards described heat-generating pipe transmitting.Because heating using microwave is to carry out on inside and the surface of heating object simultaneously, therefore when food feed liquid flows into described heating tube by described feed pipe, finally by described discharge nozzle, flowed out, being heated of it is uniformly whole, can not occur coking phenomenon at the inner surface of described heating tube.Described microwave generating unit, is the global formalism to the microwave heating equipment of existing technology maturation, should comprise the parts such as power transformer, microwave generator, transmission waveguide, shell and control and governor motion.
The time of passing through in described heat-generating pipe in order to extend food feed liquid can be worked described microwave generating unit under the lower state of operating power, and described heating tube is spiral element.Simultaneously, in the utility model, allow feed liquid fluid stable in described heating tube and be convenient to the observation to product after sterilization, between described feed pipe and described heating tube, current stabilization case is housed, between described discharge nozzle and described heating tube, manifold is housed, sample tap and temperature display meter are housed on described manifold; Concrete method of attachment is: the inlet of described feed pipe and described current stabilization case is communicated with, and the liquid outlet of described current stabilization case and described heating tube import are communicated with; The inlet of described manifold, liquid outlet are communicated with the outlet of described heating tube, described discharge nozzle respectively; For the ease of the shielding of microwave, the shell of described current stabilization case, manifold should adopt metal material.Division board is equipped with at two ends at described heating tube, the endoporus of described division board should with the airtight connection of metal outer wall of described feed pipe, discharge nozzle or described current stabilization case, manifold, the neighboring of described division board should the airtight connection with the shell of described microwave generating unit; The effect that described isolation is pulled is to prevent microwave environment leakage towards periphery.
Against existing technologies, the beneficial effects of the utility model are:
Reduced investment, disposal cost is low, saves electric energy; Homogeneous heating to material, the difficult phenomenon that is charred, convenient cleaning.
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, feed pipe, 2, discharge nozzle, 3, heating tube, 4, microwave generating unit, 5, power line, 6, current stabilization case, 7, manifold, 8, division board.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
In the utility model, the material selection of various parts is very crucial, and except existing narration and technology existing maturation above, heating tube 3 must adopt the higher plastics of glass, pottery or heat resistance to make, and can not adopt metal material.Division board 8 can adopt the sheet metal of stainless steel or coated plastics to make.The sterilization of general convection cell food, required temperature is controlled at below 100 ℃, conventionally adopts 65 ℃-95 ℃, and in the specific implementation, available apparatus regulates micro-intensity of wave in the control and regulation mechanism of microwave generating unit 4, thereby controls the temperature of food feed liquid.
