Description
Technical field
The invention belongs to the production technology of instant food, be specifically related to the process that a kind of automatic cold chain rice is produced.
Background technology
Along with the progress of society and the raising of people's living standard, and the quickening of live and work rhythm, the variation of life content, no matter be for subjective or objective consideration, people in for three meals in a day the work that spends and the time fewer and feweri, also increasing to the demand of instant staple food, the frequency that the instant food of the classes such as such as instant noodles, convenient rice noodle, instant-rice appears on people's key table increases day by day, and such present situation and demand also promote socialization that family cooks, industrialization.Antistaling instant food has catered to such requirement background and has produced.Freshness-keeping instant rice (also claiming fresh rice or instant fresh rice) should be one of food be wherein esthetically acceptable to the consumers most.So-called fresh rice, refer to that slaking also has the rice goods in certain storage time through suitably packing, also wet method instant-rice is claimed, this rice goods have normal water content, through suitable packaging and sterilization processing, can put on market, through suitably heating or not needing heating and edible after consumer buys.When instant noodles occupy large portion's fast food market share, the demand of instant fresh instant-rice also increases thereupon.
It is CN102894292A that State Intellectual Property Office discloses publication number on January 30th, 2013, name is called the application for a patent for invention document of a kind of instant fresh rice and production method and mould, the process that instant automatic cold chain rice in the document is produced mainly is carried out according to following operation: eluriated in the continuous wash mill of rice by rice material (polished rice), then be filled in the complex pocket of the flanging three side sealing that digestion resistant composite membrane (based on OPP/PE) is made by rice quantitative filling packer by filling quantitatively for rice and the water (water yield be rice material weight l.5 times) after eluriating, the complex pocket of the flanging three side sealing that the present embodiment is used, it is a kind of quadrangle (such as cuboid) complex pocket of openings at one side, for the benefit of rice maturing process is shaping, complex pocket has suitable " playing wall height ", utilize vacuum packing machine to inflated with nitrogen (substantially being driven out of by the air in space in bag) in the complex pocket of the good rice of own filling and water, to complex pocket, sheaf space is full of (the about l/6 to 1/5 that aeration quantity accounts for rice material and water cumulative volume) by nitrogen substantially, sealing, now complex pocket two ends are all sealed, obtain rice semi-finished product, then the rice semi-finished product sealing mouth are loaded in shaper, put into high temperature sterilization still together with mould and carry out the process of slaking process for sterilizing, concrete slaking process for sterilizing condition is: normal temperature is warming up to l21 DEG C, this about 8 minutes control time temperature rise period (temperature rise period), to maintain under 121 ± 0.5 DEG C of conditions constant temperature afterwards 28 ± 2 minutes, then be cooled to about 40 DEG C, this cooling stage control temperature DEG C to be cooled to 40 DEG C time from l21 ± 0.5 is about l0 minute, in this maturing process, rice suitably expands and the space existed before in filled composite bag, and by shaper restriction, the described complex pocket of resistance to boiling realizes the airtight parcel of gapless to the ripe rice in it, mould can be taken out in sterilization kettle after being cooled to 40 DEG C, then rice is taken out from mould, rice wrapper surface can be dried as required, be cooled to room temperature further, obtain instant fresh rice product.There is following defect in above-mentioned Patent Application Publication: one, is directly eluriated in the continuous wash mill of rice by rice material (polished rice), damage by water consumption is quite large, China's water resource is shorter now, and the significant losses of water resource does not meet the requirement of the energy-conserving and environment-protective that China advocates completely; Two, be filled in complex pocket by rice quantitative filling packer by filling quantitatively for the meter Yu Shui after elutriation, filling precision is low, can not ensure the quality of product; Three, loaded in shaper by the rice semi-finished product sealing mouth, put into high temperature sterilization still and carry out the process of slaking process for sterilizing, this operation sterilization is not thorough, and not only food hygiene can not ensure, and the shelf-life of product can be caused shorter, is unfavorable for depositing of product.
In addition, it is CN102657309A that State Intellectual Property Office discloses publication number on September 12nd, 2012, name is called a kind of application for a patent for invention document of processing method of fresh rice, the processing method of the document, comprise the steps: A) soaking disinfection, disinfectant is added to sealing fermentation vat, the grain of rice soaks certain hour via fermentation vat; B) steam sterilization, enter in steam box through the grain of rice soaked out, utilize the heating tube disinfectant heated in tank to produce disinfectant steam and carry out two-stage sterilization; C) cooling sterilization, the rice steaming out through steam box, via cooling sterilization pool, adds disinfectant in cooling sterilization pool, and rice is cooled by disinfectant through cooling sterilization pool; D) mounted box, cools from the sterilization of cooling sterilization pool the rice breaing up out, is filled in box; E) sterilizing before sealing, utilizes sterilization water generates steam to carry out sterilization treatment at enclosed cavity the packed meal installing rice; F) seal, the packed meal of sterilizing is delivered in containing vacuum sealing machine and seals; G) sterilizing after sealing, the packed meal sealed, then carry out sterilizing place.Above-mentioned patent is our company's exploitation, the advantage of this technical scheme is that sterilization is thorough, health can be prepared, safety, the fresh rice that fresh keeping time is long, but after this patent mainly adopts and first cooks meter Jin Hang, again ripe rice is broken up to the technique of mounted box, mounted box efficiency is lower, and quantitative accuracy is lower, in addition, while conveying suction, the rice bran dust on rice surface is together transported on meter Dou, meter Wei Jing dedusting directly enters immersion operation, the grain of rice is after shelling, certain rice bran all can be carried in surface, if these rice brans can dissolve in the water soaked after entering down one technique, continuous seepage can make the water of immersion stick with paste, thus make to stick together between rice and rice, if and stick to rice on equipment and stick with paste not wash clean clearly and also can produce bacterium.
