Description
Technical field
The invention belongs to the production technology of the central kitchen food of cold chain, and in particular to a kind of central kitchen food of cold chain is rapidly
The process of cooling.
Background technology
With quickening, the life content of the progress and the improvement of people's living standards of society, and live and work rhythm
Variation, either for it is subjective or it is objective consider, the work and time that people spend in by three meals in a day be more next
Fewer, the demand to instant staple food is also increasing, the convenient food of the class such as instant noodles, convenient rice noodle, instant-rice
The frequency that product are appeared on people's key table increasingly increases, and such present situation and demand also promote socialization, the work that family cooks
Industry.Antistaling instant food has catered to such requirement background and produced.Freshness-keeping instant rice (also referred to as fresh rice,
Or instant fresh rice) should be one of food for being wherein most esthetically acceptable to the consumers.So-called fresh rice, refers to cure simultaneously
The rice product with certain storage time, also referred to as wet method instant-rice through appropriate packaging, this rice product has normal
Water content, it is suitably heated or be not required to after consumer's purchase by appropriate packaging and sterilization processing, you can put on market
Heating is edible.In the case where instant noodles occupy big portion's fast food market share, the demand of instant fresh instant-rice
It is consequently increased.
State Intellectual Property Office disclosed Publication No. CN102657309A, a kind of entitled guarantor on the 12nd in September in 2012
The application for a patent for invention document of the processing method of fresh rice, the processing method of the document comprises the following steps：A) soaking disinfection,
Disinfectant is added to sealing fermentation vat, the grain of rice soaks certain time via fermentation vat；B sterilization) is steamed, it is soaking to come out
The grain of rice enter in steam box, utilize heating tube heating tank in disinfectant produce sterilization water vapour carry out two-stage sterilization；
C) cooling sterilization, the rice for steaming out through steam box is via cooling sterilization pool, and in cooling sterilization pool addition disinfectant, rice is through cold
But sterilization pool is by sterilization water cooling；D) mounted box, the rice for breaing up out from cooling sterilization pool sterilization cooling, is filled in box；
E sterilized before) sealing, the packed meal for installing rice is produced into steam using disinfectant in closing chamber carries out sterilization treatment；F) seal, will
The packed meal of sterilizing is sent in containing vacuum sealing machine and sealed；G sterilized after) sealing, seal the packed meal completed, then sterilized
Place.
Above-mentioned production technology, when to the food cooling of curing, not using the production technology of first precooling, then quickly cooling, therefore
The food produced easily shrinks, so as to have impact on edible mouthfeel.
The content of the invention
It is difficult to shrink it is an object of the invention to provide one kind, the central kitchen food of the good cold chain of rice mouthfeel is rapidly cooled down
Process.
To achieve the above object, the technical solution adopted in the present invention is：
The process that cold chain center kitchen food is rapidly cooled down, comprises the following steps：A, standby nitrogen：Open cooling storehouse
Refrigerating plant, by cooling be down to nitrogen -18 DEG C~-25 DEG C it is standby；B, the advance precooling in precooling storehouse：In advance will using central air-conditioning
Temperature in precooling storehouse is down to 8 DEG C~12 DEG C；C, food materials entrucking conveying：Staple food to be cooled and dish are loaded into jiggering；D, food
Material precooling：It will be equipped with the jiggering feeding precooling storehouse of staple food and dish, precooling 10 minutes~30 minutes；E, feeding cooling storehouse：It will rise
Drop platform to rise promoting cooling storehouse equipped with staple food to be cooled and dish jiggering, and temperature-sensitive probe is inserted in cooled food
The heart；F, the cooling of pass storehouse：Cooling storehouse is closed, the air in cooling storehouse is replaced into -18 DEG C~-25 DEG C of nitrogen, -18 DEG C are utilized
~-25 DEG C of nitrogen is cooled down, when the central temperature that temperature-sensitive probe detects cooled food is down to 10 DEG C, by raising one's voice
Device sends cooling and finishes prompt tone；It is G, temporary：Hear that cooling is finished after prompt tone, the discharge door of cooling storehouse is opened, by liftable
Platform rises, in the temporary room that jiggering is pushed into 8 DEG C~12 DEG C, the technique for completing rapidly to cool down.
In the step A, the best alternate temperature of the cooling nitrogen is -22 DEG C.
In the step B, the temperature in precooling storehouse is down to 10 DEG C in advance using central air-conditioning.
In the step F, when the central temperature of cooled food is down into 10 DEG C, the time of cooling is not more than 20 minutes.
In the step G, the temperature in temporary room is down to 10 DEG C in advance using central air-conditioning.
Beneficial effects of the present invention：Due to the production technology of first precooling, then quickly cooling, therefore the food produced is difficult contracting
Water, the rice processed it is in good taste.
