Description

A kind of production method of dried bean-curd slivers

Technical field

The present invention relates to the methods for making bean product, specifically, it is related to one kind making dry bean curd by raw material of soybean The method of silk.

Background technology

Soybean contains abundant and comprehensive nutrient, and the convenient bean product of multiple eating can be processed into using soybean, Middle shredded soybean curd, dried bean curd are fewer than bean curd water content, and protein content is a kind of food full of nutrition higher than egg, lean meat.Mesh The production method of preceding bean product is mostly that traditional immersion-defibrination-filtering-mashing off-plus coagulator-are squeezed into dry beans at tender bean curd- Corruption-chopping is at shredded soybean curd.Product water content made of this method is high, it is difficult to hide long and be unfavorable for transporting for long-distance, on overcoming State deficiency.

Invention content

The invention aims to provide a kind of and entirely different dried bean-curd slivers of traditional manufacturing technique production methods, i.e., For dry technology for production, it can be achieved that continuous production, manufactured product is freshness-retained and can store for a long time.

The invention is realized in this way：

Raw soybeans remove impurity, miscellaneous beans and damaged beans through screening and obtain high quality soybean, then match through broken-decortication-degreasing-crushing- Side-tabletting, chopping-drying-quality inspection are packed up to dried bean-curd slivers.

To make shredded soybean curd flexible, after water hair it is not poor constantly, the present invention, which takes, handles material bean decortication, peeling rate 7- 8%;To keep the whiteness of product color, oil machine is rolled into decortication beans quarrel input and carries out partially skimmed, proposes 5% soya-bean oil.This portion Divide soya-bean oil, 35-40% therein is returned again in dispensing, to improve content fatty in bean powder, while can also increase the light of product Damp degree;Taste is given birth to improve the intrinsic beans of soybean, salt and alkali face are added in bean powder, both compositions are to antiseptic insect-repelling in addition There is certain effect, matches：

Salt 1.0%（wt%）

Alkali face 1.0-1.5%（wt%）

Remaining is bean powder.

The salt and alkali face need to be first dissolved in the water for accounting for bean powder weight 50-55% mixed with bean powder again in homogeneous phase aqueous solution It closes.Mixture is squeezed into the beans piece of 5-8cm wide through heat seal tablet press machine at a temperature of 120-130 DEG C, and silk is cut into screw-rolling machine, then Drying machine is dried at a temperature of 70-80 DEG C to dry, and so that material moisture is less than 12%, in favor of storage, transport and storage life It is long.According to dried bean-curd slivers bag distribution packaging made of the method for the present invention, is impregnated 3-5 minutes, extracted with warm water when eating, repeatedly two Secondary, flavouring material can be propagandized hotly, is cold and dressed with sauce, manufacture various delicious foods.

The production method of dried bean-curd slivers of the present invention takes partially skimmed, hot pressing, rolled thread, dries, dissolves salt and alkali etc. and is new Technique, without broken, storage life is no less than 4 months fresh and tender, soft, flexible after manufactured product water is sent out.With reference to embodiment The present invention is described in further detail.

Embodiment 1：100 jin of raw soybeans are taken, dried bean-curd slivers are made through following technical process：

（1）Screening：Raw soybeans remove impurity, miscellaneous beans and damaged beans through screening, obtain 95 jin of high quality soybean;

（2）Decortication：Beans quarrel is broken by screening gained high quality soybean, is peeled with air blower, the beans that must peel are cut 87 jin;

（3）Degreasing：Oil machine is rolled into decortication beans quarrel input and carries out partially skimmed, 4 jin of soya-bean oil is proposed, becomes beans piece;

（4）It crushes：Beans piece after degreasing is ground into 83 jin of the bean powder of 70-80 mesh with pulverizer;

（5）Formula：Bean powder is sent into the equipment with agitating device, 1.4 jin of the soya-bean oil proposed when degreasing is added, adds and contains There are 43 jin of 0.85 jin of salt and the aqueous solution in 0.85 jin of alkali face, being sufficiently stirred makes it be uniformly mixed;

（6）Tabletting, chopping：Mixture is inputted into roller heat seal tablet press machine, the beans of 5-8cm wide are squeezed at a temperature of 120 DEG C Then piece is cut into silk with screw-rolling machine;

（7）Drying：Shredded soybean curd is sent into drying oven, at a temperature of 70 DEG C, is stopped 6 minutes, drying is dried, and moisture content is made to be not more than 12%;

（8）Quality inspection, packaging：After dry bean curd sampling quality inspection qualification, weigh, packaging into products.

Embodiment 2：Take 100 jin of raw soybeans, manufacture craft with embodiment 1, the difference is that：High quality soybean is 95 Jin obtains beans and is cut 88 jin, 84 jin of bean powder is obtained after degreasing, 1.6 jin of soya-bean oil is added and containing 0.86 jin of salt, 1.3 jin of alkali faces after decortication 50 jin of aqueous solution, so that it is sufficiently mixed uniformly.Its heat seal pelletizing temperature is 130 DEG C, and drying temperature is 80 DEG C.
