Description
Technical field
The utility model relates to a kind of food processing machinery and equipment, especially relates to a kind for the treatment of facility that is applicable to accesary foods processing and frozen food processing.
Background technology
In recent years, along with the extensive concern of people to the food nutrition quality and safety, the traditional food processing industry faces huge challenge, and some high-technologies can with the utilization rate of effective raising food resource and the increment of food, satisfy people's demand to a certain extent in food.Wherein a kind of new and high technology that ultrasonic new development is in recent years just got up, it is widely used in the numerous areas such as food processing, chemistry, chemical industry, medical treatment, medicine and agricultural chemicals.The low frequency ultrasound Applications in food mainly comprises following three aspects: the 1. application in food processing, as freeze-thaw, pickled, degassed inflation, froth breaking, sterilization, filtration etc.; 2. be used for the extraction of food component, as some nutritional labelings and active component in food are extracted; 3. the application in food security is as the detection that is used for degradation of pesticide, food hazardous substance etc.The processing that low frequency ultrasound is applied to food is mainly to utilize ultrasonic cavitation effect and mechanical effect etc.Wherein, the ultrasonic cavitation effect refers to that the micro-bubble in liquid produces a series of dynamic processes of strong vibration, expansion and collapse with sound pressure variations in ultrasonic field, and the instantaneous strong pressure that this process produces and local temperature raise and can produce strong sonochemical effect to the particle that suspends in solution; Mechanical effect of ultrasound refers to the ultrasonic effect that produces when advancing in medium, it can facilitate the emulsification of liquid, the liquefaction of gel and the dispersion of solid.Using ultrasound acts on meat products, and ultrasonic wave can destroy the muscle fibril of meat, and this muscle fibril will be secreted a kind of material of thickness, and meat is sticked together, thereby increases the viscosity of meat product.Ultrasonic Radiation can produce cavitation effect and cause intergranular collision the material particles that is suspended in liquid, thereby corrodes particle surface or reduce particle size.If accept the rice in water of being suspended in of Ultrasonic Radiation, so necessarily have the part grain of rice pulverized or watchcase impaired.When cooking, these two kinds of destructions all will speed up the release of starch in the grain of rice, thereby shorten the time that colloid forms.Monika Sujka and Jerzy Jamroz are suspended in potato, wheat, corn and rice starch granule in the aqueous solution and ethanolic solution respectively, then use that frequency 20KHz, power 170W's is ultrasonic to each group effect 30 minutes, with transmission electron microscope and ESEM imaging, research finds that ultrasonic meeting makes starch particle surface form crack and depression; Ultrasonic processing can reduce viscosity, solubility and the roc profit power of starch; In addition, present higher pasty state transparency through the farina of ultrasonic processing with untreated comparing, this can be applied in a lot of food processings.
With respect to the mode that other traditional foods are preserved, frozen food has that quality better, health, quality pattern are varied, nutrition rationally, economy, instant, and be not subjected to the many merits of season, territorial restrictions.Freezing processing can slow down the bad change of food and pathogen microbial growth, reduces most biochemical reaction speed, can effectively keep food freshness, nutritive value and original local flavor.But in refrigerating process, because water volume in freezing process can expand, the large ice crystal that the moisture in food forms in refrigerating process can cause to the institutional framework of food damage to a certain degree, thereby causes the quality of frozen food to descend.In order to improve the infringement that in refrigerating process, food is caused, need to seek effectively auxiliary freezing method and improve its defective.The food product refrigeration new technologies that development in recent years is got up has high pressure food Refrigeration Technique, CAS(cell survival) freezing plant and ice-temperature technique etc., the ultrasonic auxiliary Refrigeration Technique that the utility model relates to is also one of them.Existing nucleation and the growth of inhibition crystal that studies show that inner ice crystal in ultrasonic wave energy promotion Food Freezing Process, a large amount of micro-bubbles that the ultrasonic cavitation effect produces can be used as the necessary nucleus of ice crystal in freezing process, and the shock wave that forms after ultrasonic cavitation and microjet can brokenly have ice crystal, the tiny ice crystal that formation disperses becomes the small crystal nucleus in freezing process, thereby reduces the mechanical damage effect to tissue.Nalajala and Moholkar research concentration 15%(w/w) in sucrose solution, the secondary nucleation of ice crystal is found, when not applying ul-trasonic irradiation in freezing process, the dendroid ice crystal can be grown up; After applying certain hour ultrasonic, the dendroid ice crystal can be split into many small crystal nucleus.Hossein Kiani etc. study ultrasonic impact on the ice crystal size in freezing agar gel sample, discovery is in agar gel sample refrigerating process, the size of the ice crystal in the agar gel sample of ultrasonication is obviously less than undressed, and the microstructure of the sample after processing is finer and close.
The utility model equipment operating is simple, is suitable for amplifying producing.Can improve to a certain extent the quality of food with ultrasonic accesary foods processing; Using ultrasound is assisted quick-frozen food, can shorten cooling time, improves the quality of quick-frozen food.
