Sea cucumber or abalone vacuum-superheat steam drying system
Technical field
The utility model relates to the processing method of a kind of sea cucumber or abalone, particularly relates to a kind of sea cucumber or abalone vacuum-superheat steam drying system.
Background technology
Sea cucumber, no cholesterol, low fat, high protein, and be rich in various trace elements, be the high health food of nutritive value, and have antitumor and anticoagulant effect.Yet adopting of sea cucumber caught seasonality by force, and very easily self-dissolving, must in time take effective means to carry out fresh-keeping and the processing processing after going to sea.According to statistics, 90% sea cucumber is processed to various dried products in the world.At present, the drying processing method of domestic sea cucumber has traditional suning method, heat pump drying method, micro-wave vacuum method and vacuum freeze-drying method usually.Traditional sea cucumber dry-making processing technology is complicated, and normally high temperature is hung salt and coarse, and concrete processing method is: fresh and alive sea cucumbers removes internal organ, clean, boil boil, mix salt, down cylinder, roasting ginseng, mix ash, airing.The sea cucumber salt content that processes like this is too much, and quality declines to a great extent.Heat pump is a kind of from low-temperature heat source absorption heat, and make its heat energy apparatus that under higher temperature, is used as effective heat energy, have thermal efficiency height, characteristics such as energy-conservation, but because what adopt is heated-air drying, the surface of sea cucumber easily forms duricrust, influences the rehydration of sea cucumber.Micro-wave vacuum is to utilize the microwave rapid and uniform heating, under vacuum condition, make water evaporates, be to combine a microwave drying and vacuum drying new technology of advantage separately, have advantages such as rate of drying is fast, the time is short, but be easy to generate the dry over-education phenomenon of sea cucumber.Vacuum Freezing ﹠ Drying Technology is that water-containing materials is freezed under low-temperature condition, under vacuum condition, make then ice directly distillation for steam and drain, thereby slough the new and high technology that moisture in the material makes dry materials, the existing application in the sea cucumber deep processing.But higher because of production cost, difficulty is popularized.
Abalone is a kind of famous and precious marine product.The effect that the prosperity of abalone muscle of foot, delicious flavour, nutritious, the polysaccharide that extracts in the abalone have the growth of obvious suppression interior tumor cell, improve antioxidant ability of organism.That abalone generally is divided into is fresh and alive, tin product, 3 kinds of products of dried product, and every kind of product is different because of the difference local flavor of its quality and processing method, and wherein dried product is produced abalone, occupied very big proportion in the process of consumption.Abalone its physicochemical properties, histological structure in drying process change, and the soft yolk effect appears in inside, substantially exceeds the Fresh abalone fish aspect texture, are subjected to liking of the China and the country in Southeast Asia people deeply.
At present, the drying processing method of domestic abalone has traditional natural drying method and hot-air seasoning usually.Traditional natural drying method generally need be passed through salt marsh, poach, be hung a series of coarse, complicated manufacturing procedures such as solarization, simultaneously, the process of natural drying is wayward, be subjected to weather effect bigger, the labour intensity height, sanitary condition is poor, easily sneaks into impurity in the process, can't satisfy requirement of large-scale production.Heated-air drying is most widely used now a kind of industrially drying method, because of its adaptability is strong, operates, controls simply, and sanitary condition better is widely used in the aquatic products drying.But because employing is heated-air drying, the surface of abalone easily forms duricrust, influences the rehydration of abalone.
The utility model content
The purpose of this utility model is exactly for overcoming the above-mentioned shortcoming of prior art, provide a kind of have rational in infrastructure, easy to use, can dry sea cucumber or abalone can keep its nutrient loss few again, the sea cucumber or the abalone vacuum-superheat steam drying system of advantages such as and it is good to make dried sea cucumber or abalone have the rehydration performance, and organoleptic quality is good.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sea cucumber or abalone vacuum-superheat steam drying system, it comprises housing, is provided with charging tray in housing, sea cucumber or abalone place on the charging tray; Housing is connected with vacuum control unit with steam raising plant respectively; Be provided with the drying aid device on the housing of corresponding position above the charging tray, be provided with blower fan below charging tray, the charging tray bottom then is connected with Weight detecting device; Also be provided with temperature control system in the simultaneity factor.
Described drying aid device is ultrasonic transducer or far-infrared ray drying device or microwave drier.
Described steam raising plant is a steam generator, and it is communicated with housing by steam control valve.
Described Weight detecting device is a weight continuous detecting display system.
Described vacuum pressure device comprises vavuum pump, and it is connected with moisture trap, and moisture trap is communicated with housing by the vacuum switch valve; Be provided with discharging valve in the moisture trap bottom, on housing, also be provided with electro connecting pressure gauge.
The utility model is put into the vacuum overheat steam drying device with pretreated sea cucumber or abalone, electric heater in the start-up temperature control system makes device reach predetermined temperature, vavuum pump in the starting pressure control system begins to vacuumize then, until reaching high vacuum (emptying air), then opening the steam inlet valve makes saturated vapor enter drying device, until reaching dry required vacuum, and make saturated vapor become superheated steam.Open blower fan driving superheated steam and in housing, circulate, sea cucumber or abalone are carried out drying, open ultrasonic transducer, far-infrared ray drying device or microwave drier simultaneously it is carried out combination drying.Along with the continuous evaporation of moisture in sea cucumber or the abalone, device vacuum must descend, and can restart vavuum pump this moment redundant moisture is discharged, and the vacuum in the dry run is controlled by control pressurer system, keeps the detection method condition of requirement.Get final product the weight change of on-line measurement sea cucumber or abalone in the experiment by the weight continuous detecting system, and then definite moisture content decline situation, grasp and control dry process, moisture content until sea cucumber or abalone reaches required requirement, stop drying, open intake valve and make the pressure in the drying box return to atmospheric pressure state, and sea cucumber or abalone are taken out, detect.
The beneficial effect of the utility model patent is: the dried sea-cucumber or the abalone rehydration of pressing the utility model processing are good, can keep the multiple active skull cap components of sea cucumber or abalone, can make the water of sea cucumber or abalone send out the time again and shorten greatly.
