The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment device that the present invention is used for pressing bean curd is further described.
Fig. 1 is the structural representation of embodiments of the invention 1.Embodiment 1 is a kind of better simply enforcement structure.Shown in accompanying drawing 1, container 1 and outer cup 2 are one, and promptly the top of same cup is container 1, and the bottom promptly is outer cup 2, and separate with screen pack 12 centre.Screen pack 12 constitutes the bottom of container 1, and the space between screen pack 12 and the outer cup 2 constitutes water containing chamber 3.Owing to need in container 1, add jellied bean curd, so this container 1 container of opening preferably.Therefore, when the needs pressing bean curd, earlier jellied bean curd is poured in the container 1, covered seal cover 5, thereby form the space of a relative closure, the inflator pump 4 (or similar charger) of opening then and being connected on the seal cover 5 gets final product.Under the effect of inflator pump, make container 1 inner air pressure increase, jellied bean curd is formed a kind of malleation; Most of moisture in the jellied bean curd is deviate from from screen pack 12; Flow into water containing chamber 3, the sub-fraction moisture in the jellied bean curd also flows in the water containing chamber 3 through screen pack 12 under the effect of deadweight, thereby realizes the dehydration of jellied bean curd; Through the pressurize certain hour, bean curd is promptly plastic again.Can the water in the water containing chamber 3 be discharged through the drainage switch 21 of opening outer cup 2 bottoms then, be convenient to pressing bean curd next time.
Present embodiment can also further be simplified to shown in accompanying drawing 6; Promptly cancel cup 2 and water containing chamber 3 outside the cup bottom, only keep cup 1, and filtering holes (filtration) is set at cup 1 wall or bottom; In charger 4 pressure processes, the moisture in the jellied bean curd is directly discharged through filtering holes and is got final product.This moment is as long as guarantee that the upper surface of jellied bean curd or bean curd hides filtering holes fully, can realize the contactless pressing bean curd through positive air pressure in the pressing process.
Fig. 2 is the structural representation of embodiments of the invention 2.It comprises the container 1 that is used to hold jellied bean curd; The outside of container 1 is provided with its one the outer cup 2 that is connected (being fastenedly connected like welding or through seal); Form water containing chamber 3 between outer cup 2 and the container 1, the wall of container 1 and bottom are provided with the filtration 11 that is communicated with and is used for discharging jellied bean curd moisture content with water containing chamber 3, and the opening part on container 1 top is provided with seal cover 5; Be connected with charger 4 on the seal cover 5, this charger 4 is connected with container 1.Filtration 11 in the present embodiment is to be set directly on the container 1 filtering holes.
After jellied bean curd being poured in the container 1, (in order to reach effect preferably, the height of jellied bean curd need hide extreme higher position, filtering holes place on the container 1 to cover seal cover 5; Thereby make a kind of relative sealing state of the interior formation of container); Under suitable temperature conditions, open inflation in 4 pairs of containers of charger 1, thereby make the jellied bean curd surface form malleation; Moisture in the jellied bean curd is promptly discharged from filtering holes, gets in the water containing chamber 3.Moisture in jellied bean curd is discharged to a certain degree, and through the pressurize certain hour, bean curd is promptly plastic.Discharge the ponding in the water containing chamber 3 for ease, on the bottom of cup 2 or the sidewall draining plug or drainage switch 21 are set outside.
Enforcement 3 is basic identical with the structure of embodiment 2.Shown in accompanying drawing 3, its difference is that container 1 is a kind of relations that are sealed and matched with outer cup 2.In moulding bean curd process, their position is relatively-stationary, and after the bean curd moulding, container 1 can be extracted in outer cup 2, can certainly not extract.Ponding in the outer cup 2 can directly be poured out or discharge through drainage switch is set.Therefore, when opening inflator pump 4, owing to be in a kind of sealing state in the container 1, inflator pump 4 makes the jellied bean curd upper surface receive malleation, thereby makes that the moisture in the jellied bean curd enters in the water containing chamber 3 through filtering holes 11a in the container 1.Moisture in jellied bean curd is discharged to a certain degree, and through the pressurize certain hour, bean curd is promptly plastic.Because container 1 and outer cup 2, seal cover 5 have also constituted a closed container jointly, therefore in pressure maintaining period, even the upper surface of bean curd (or jellied bean curd) is lower than the filtering holes 11a of extreme higher position, also do not influence the moulding of bean curd.
Embodiment 4 is mainly that with the difference of embodiment 2 filtration is different, and shown in accompanying drawing 4, the filtration among the embodiment 4 comprises and is set in the container 1 and forms the screen pack 12 of sealing state and be arranged on the delivery port 13 that is communicated with water containing chamber 3 on the container 1.This screen pack 12 also can replace with filter cloth, and the filter cloth that directly will drench is fitted in container 1 inwall and gets final product.Therefore, when the jellied bean curd of in container 1, packing into, cover seal cover 5; When opening charger 4, make in the container 1 to form a kind of pressured state in the top of jellied bean curd (height of jellied bean curd need be higher than the height at the filtering holes place on the screen pack 12 in theory, but in fact; When the jellied bean curd height is lower than the height at the filtering holes place on the screen pack 12; Because container 1, outer cup 2, seal cover 5 have constituted a seal cavity jointly, therefore in inflation pressure process, also can the moisture in the jellied bean curd be extruded); Thereby the moisture in the jellied bean curd that makes is deviate from, and forms bean curd.
Embodiment 5 also is mainly that with the difference of embodiment 1 container 1 is different with the structure of outer cup 2; Shown in accompanying drawing 5; The closed container that two halves combined about container 1 was served as reasons among the embodiment 5; Filtration is the tabular screen pack 12 that is arranged on container 1 bottom, and is arranged on the delivery port 13 that is communicated with water containing chamber 3 on the container 1.Outer cup 2 similar pallets, directly connecting together and form with container 1 is tightly connected.Charger 4 is connected on the sidewall of container 1 the first half.Therefore, when the jellied bean curd of in container 1, packing into, when opening charger 4, make the top of container 1 interior jellied bean curd form a kind of pressured state, thereby the moisture in the jellied bean curd that makes is deviate from formation bean curd.
The device that is used for pressing bean curd in the foregoing description is owing to through form the space of a relative closure on the top of jellied bean curd, form malleation thereby under the effect of charger, make in this space; Moisture in the jellied bean curd is deviate from,, made jellied bean curd finally form bean curd through certain pressurize; Therefore simplified the structure of equipment; Alleviate the manpower work significantly, also avoided pressing plate directly to press jellied bean curd simultaneously, guaranteed the safety and sanitation of food.The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, therefore, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within the protection domain of claim of the present invention.
