Utilize centrifuge soaked soya bean to be sucked fiberizer mill soya-bean milk, remove bean dregs through repeatedly centrifugal treating and obtain elementary soya-bean milk;
(2), mashing off: the elementary soya-bean milk obtained in step (1) is carried out mashing off process, then carries out screening the pulp process, clear up remaining bean dregs again, then the ripe slurry obtained after screening the pulp process is transported to a slurry bucket, utilizes screen filtration in course of conveying;
(3), some slurry: during point slurry, bittern is is evenly clicked and entered on stirring limit, limit, and selecting when presenting Tofu pudding to ripe slurry, the temperature selecting soya-bean milk during slurry remains on 70 DEG C ~ 89 DEG C;
(4), crouching brain: after ripe slurry solidifies, leave standstill 15 ~ 20 minutes, until ripe slurry is completely cementing, condense, precipitate formation Tofu pudding;
(5), slurry is sprinkled: after Tofu pudding condensation, open a dump valve for slurry bucket, by the carrier pipe arranged, Tofu pudding is transported to rationed bucket from top to bottom to carry out sprinkling slurry, before sprinkling slurry, first by compress framework, infantees is pressed onto in template, then starts evenly to sprinkle slurry to infantees, gathering infantees after completing, place second layer infantees again, complete second time and sprinkle slurry, by that analogy;
(6), squeeze shaping: the multilayer Tofu pudding wrapped by infantees squeezing 60 ~ 80 minutes, distributes until anhydrous in infantees;
(7), white embryo cooling moulding: after having squeezed, peel off the outer field infantees of white embryo dried bean curd, it is cooled, finally it is cut into slices, obtain the white embryo finished product of suitable size.
In prior art, artificial or mechanical type must be carried out to Tofu pudding after crouching brain and break brain, and the carrier pipe used after broken brain only plays a part to carry Tofu pudding, and after adopting above-mentioned manufacture craft, the present invention breaks brain operation without the need to the artificial or mechanical type carried out in original technology, but complete broken brain to Tofu pudding by Tofu pudding in the process that carrier pipe flows, its principle is: the Tofu pudding in carrier pipe is because of self gravitation acceleration flowing, make to produce extrusion and collision and friction between Tofu pudding and Tofu pudding and between Tofu pudding and tube wall, thus smash Tofu pudding, reach brokenly the effect of brain, avoid the problem that dried bean curd mouthfeel is older.
After solving the problem how avoiding dried bean curd excessively old, this invention also solves the problem how avoiding dried bean curd excessively tender, in prior art, the temperature range of some slurry is generally at 50 DEG C ~ 90 DEG C, as too low in fruit dot slurry temperature, Tofu pudding cannot cementation and formation, form folder slurry (unseasoned soya-bean milk), the crouching brain time should not control, the dried bean curd that the Tofu pudding selecting out is made usually does not have elasticity because of too tender, as too high in fruit dot slurry temperature, bulk Tofu pudding cannot be become by cementation and formation, and a slurry temperature controls within the scope of 70 DEG C ~ 89 DEG C by the present invention, this belongs to suitable temperature in a slurry temperature range, the speed of Tofu pudding cementation and formation can be accelerated, also more easily control on the crouching brain time, even if Tofu pudding does not have complete cementation and formation in crouching brain process, flow through in the process of carrier pipe at it, it also can reach well-done completely, cementing status, there will not be folder slurry problem.
Visible manufacture craft of the present invention compared to existing technology, more laborsaving, broken brain equipment before need not using, self gravitation is relied on to reach brokenly brain effect completely, reduce cost, shorten Production Time, and after breaking brain according to the method Tofu pudding evenly, finer and smoother, the white embryo dried bean curd made is namely not tender not old yet, has better elasticity and strength road.
Further restriction, in described step (5), the caliber of carrier pipe is 20 ~ 200mm.If the caliber of carrier pipe is too large, squeezing effect between Tofu pudding is low, broken brain weak effect, carrier pipe caliber is less, Tofu pudding break after brain thinner evenly, but the caliber of carrier pipe also should not be too little, if caliber is too little, the bulk Tofu pudding just entered easily blocks carrier pipe, and therefore the caliber of carrier pipe should be suitable for making Tofu pudding to move smoothly through carrier pipe, can also meet brokenly effect needed for brain.
Further restriction, in described step (5), the pipe range of carrier pipe is 0.5 ~ 2m.If pipe range is oversize, not only increase cost, and bad layout, Tofu pudding also easily blocks, if pipe range is too short, cannot reach brokenly the Expected Results of brain after Tofu pudding flows through carrier pipe.
Reaching under identical broken brain effect, the carrier pipe that caliber is less can shorten pipe range, and the carrier pipe that caliber is larger needs to increase pipe range, according to actual needs, can select the size of carrier pipe.
Further restriction, in described step (5), carrier pipe is the structure that import reduces gradually along Way out caliber.The pipe structure of above-mentioned restriction be conducive to Tofu pudding carrier pipe in different positions by: bulk Tofu pudding-fritter Tofu pudding-bulky grain Tofu pudding-granule Tofu pudding grinds step by step, improves brokenly brain effect.
Further restriction, in described step (5), carrier pipe at least has two bending parts.The setting of bending part can strengthen collision between Tofu pudding and tube wall and friction further, makes Tofu pudding can meet broken brain effect more quickly.
Detailed description of the invention
In order to make those skilled in the art, the present invention may be better understood, further illustrates technical solution of the present invention below by embodiment.
