Problems solved by technology

[0007] ①. At present, the production process of boxed tofu needs to go through secondary heating and primary cooling. Although the industrial control of the entire production process has been realized, the energy consumption is more than three times that of the traditional process, especially the energy consumption of the cooling process of soybean milk is greater than that of subsequent heating. energy consumption, in the world energy and CO 2 Under the situation that emissions are of great concern, whether it is in terms of energy saving or emission reduction, the high energy consumption also makes the producers of this box of tofu face huge economic pressure
[0008] ②. At present, in the production of boxed tofu, in order to realize the rapid and uniform mixing of soybean milk and coagulant, it is necessary to use a high-pressure high-speed mixer, which is an industrial mixing equipment. For the mixing of soybean milk and coagulant with a large component ratio, high The pressure is high and the flow rate is high, and the boxes of tofu on the market are mainly small packages of 200 to 1,000 grams. In this way, when the mixed soybean milk and coagulant are filled into the box, splashes will be formed due to a large impact, and foaming w

Embodiment 1

[0045] figure 1 It is the front view of the soya-bean milk-coagulant mixer that the embodiment of the present invention adopts; figure 2 for figure 1 left view of .

[0046] The soybean milk used in this example is boiled and matured according to a conventional method, and kept at 85-95° C. for mixing and coagulation with a coagulant.

[0047] Such as figure 1 and figure 2 As shown, the soya-bean milk-coagulant mixer used in this implementation has at least one coagulant delivery pipe 1, a soya-bean milk delivery pipe 2 with a pipe diameter larger than the coagulant delivery pipe 1 and one end closed, and a soya-bean milk delivery pipe 2 close to the closed end. The side wall is connected and the mixed slurry output pipe 3 that changes the flow direction of the material, the at least one coagulant delivery pipe 1 extends from the closed end of the soybean milk delivery pipe 2, and the coagulant delivery pipe 1 is connected to the soy milk delivery pipe 2 The protruding ...

Embodiment 2

[0061] The production method of the soybean milk used in this example is as follows: before pulping, the soybean raw material is crushed, and the germ and soybean skin are removed to obtain soybean cotyledon fragments. After crushing, the germ in soybeans can be removed by sieving, and the skin can be easily removed by winnowing. Soybean cotyledon fragments can be completed by conventional means in this field. For example, using a crusher to crush the raw beans requires only crushing the raw beans into appropriate fragments. In this embodiment, the soybeans are crushed into 4 to 6 petals (1 / 4-1 / 6 crushed cotyledon), at this time, it only takes 30-45 minutes to complete the water absorption process of soybean cotyledon crumbs, and the water absorption reaches 1.2-1.3 times of the weight of cotyledon crumbs, which is more conducive to meeting the pulping requirements.

[0062] Specifically, the crushed soybean cotyledons (1 / 4 to 1 / 6 grains) are soaked in tap water with a hardne...

Embodiment 3

[0069] Adopt the soybean milk-coagulant mixer identical with embodiment one and the soybean milk identical with embodiment two, coagulant is the CaSO that mass percent is 10% 4 2H 2 O suspension. The storage tank is agitated with an electric stirrer to maintain the suspension state, and the coagulant is transported using an adjustable-speed gear pump (realizing that the pump pressure can be adjusted to 1.5Kg / cm 2 ).

[0070] Turn on the soymilk valve and gear pump, mix 85°C soymilk and coagulant in the soymilk-coagulant mixer, use five 400mL packaging containers to receive 350mL of the mixed solution, keep warm at 85°C for 20 minutes, cool naturally to room temperature, and pour gently out. All 5 cups of samples can maintain a complete cup shape without deformation within 1 hour, and the precipitated water after 12 hours accounts for 10-12% of the total weight of tofu. The hardness and elasticity of the tofu prepared in this example are better than those of the commerciall...

Abstract

The invention discloses a production method for boxed bean curd and the boxed bean curd. The production method for the boxed bean curd comprises the following steps of: boiling soybean milk by taking soybeans as raw materials; controlling the temperature of the boiled soybean milk to be above 85 DEG C; mixing the boiled soybean milk with a coagulating agent; and filling the mixture into a packing container; keeping the temperature of mixed milk of the soybean milk and the coagulating agent in the packing container for 10 to 30 minutes; and solidifying to form the boxed bean curd. The production method has a scientific process and simple steps. According to the production method, defects in the prior art are overcome, a solidification process of the soybean milk can be more effectively controlled, industrialized production can be really realized, and the aims of reducing energy consumption to a great extent, simplifying equipment and diversifying varieties are fulfilled, and boxed lactone bean curd and boxed southern bean curd and northern bean curd which fit conventional taste can be prepared.

Description

technical field [0001] The invention relates to food technology, in particular to a method for producing boxed tofu and boxed tofu. Background technique [0002] The tofu varieties currently on the market can be mainly divided into southern tofu, northern tofu and lactone tofu (box tofu) from the use of coagulants. The coagulants used in the processing of southern tofu and northern tofu are salt bittern (mainly MgCl 2 ) and gypsum (CaSO 4 or CaSO 4 2H 2 (2), during processing, soy milk is formed into bean curd under required coagulation conditions, and then boxed; and boxed tofu is a kind of tofu solidified in a packaging container (box), compared with the first two traditional tofus, the mouthfeel is more Delicate, tender, and realize the industrialized process of packaging on the production line. Due to the difference in the properties of the coagulants, the protein coagulation effects of the three kinds of tofu are different, resulting in obvious differences in the ha...
