Problems solved by technology

However, in the traditional processing technology in the past, a large amount of water resources were consumed in the process of washing beans, soaking beans, refining and transporting beans with water. Generally, 10-15 kg of water was consumed for producing 1 kg of tofu; secondly, in the whole In the production process, eutrophic waste water needs to be continuously discharged, which causes a lot of pollution to the environment. Enterprises need to pay a lot of sewage charges for this, and spend a lot of money to build waste treatment equipment; The active nutrients are discharged along with the wastewater, reducing the nutritional and health value of soybean products. Generally, the active nutrients such as oligosaccharides, isoflavones, saponins and other water-soluble vitamins and whey protein contained in soybeans are greatly lost. According to the National Soybean Engineering Technology The research center determined that the average loss was about 70%

Embodiment 1

[0017] Get 100 kilograms of soybeans, and process them according to the following steps and techniques:

[0018] (1) Dry cleaning of soybeans: use Xφ600 cylindrical sieve sorting machine, Cφ800 spiral sorting machine, N70 air jet iron roller friction remover and other equipment, use permanent magnets to remove iron impurities, and use reaming dragons to send beans Friction removes all kinds of impurities on the surface of soybeans, the screen removes granular impurities larger or smaller than beans, and the suction fan removes dust, etc. Through the combined action of the above-mentioned machinery, the soybeans meet the cleaning requirements, and the impurity content is less than 0.3% (taken as ash) portion assay);

[0019] (2) Clean soybeans with 200T cold press or rzrx95b screw oil press for cold pressing oil (to avoid thermal denaturation of protein), and the oil yield reaches 80-90% of soybean oil content;

[0020] (3) Block defatted soybean meal is pulverized with a SF-4...

Embodiment 2

[0031] Get 100 kilograms of peanuts and process them according to the following steps and processes:

[0032] (1) For peanuts, use Xφ600 cylindrical sieve sorting machine to remove impurities, go through processes such as vacuuming by vacuum cleaners, removing iron with iron suction stones, etc., to remove all impurities on peanut kernels, and meet the food hygiene requirements with an impurity content of less than 0.3%;

[0033] (2) Remove the peanut clothes with a special machine for removing peanut kernels;

[0034] (3) Use a 200T cold press or rzrx95b screw press to extract 80-90% of the oil contained in the peanut kernels;

[0035] (4) Use the SF-400 high-speed pulverizer to pulverize the oil-pressed peanut kernels into 20-40 mesh powder;

[0036] (5) Soak the peanut powder with 3 times the amount of water for 1 hour;

[0037] (6) Use FDM-Z automatic slag separation and refining machine to add water and refine, and determine the amount of water to be added according to ...

Embodiment 3

[0042] Get 100 kilograms of soybeans and process them according to the following steps:

[0043] (1) Dry the soybeans with an ED-1500 hot air dryer. When the water content reaches about 10%, use a ZQ soybean peeler to remove the soybean skin;

[0044] (2) Soak the clean bean kernels in 3 times the weight of water, soak for 3 hours when the temperature is higher than 25°C, and soak for 6 hours when the temperature is lower than 25°C;

[0045] (3) Take out the water-absorbed bean kernels from the soaking container, put them into the FDM-2 automatic pulp and residue separation refiner for refining, and the excess soaking water can be used as additional water for refining;

[0046] (4) Just can produce same bean curd product by embodiment 1 step (5), (6), (7).

Abstract

The present invention discloses a soybean milk production method which does not produce waste water. Said method uses soybean and / or peanut as raw material and adopts the following steps: using dry method to clean raw material, cold expelling treatment, pulverizing defatted block raw material cake, soaking the defatted raw material powder, grinding to make milk and removing dregs, boiling soybean milk and homogenizing so as to obtain the invented soybean milk.

Description

[0001] This application is a divisional application of the original application date: January 20, 2004, application number: 200410001753.0, and the invention-creation name is "method for producing bean curd products without waste water". technical field [0002] The invention relates to the technical field of soybean food processing, in particular to a method for manufacturing soybean protein food without waste water. Background technique [0003] Tofu is a traditional soybean food in my country, which is deeply loved by consumers. However, in the traditional processing technology in the past, a large amount of water resources were consumed in the process of washing beans, soaking beans, refining and transporting beans with water. Generally, 10-15 kg of water was consumed for producing 1 kg of tofu; secondly, in the whole In the production process, eutrophic waste water needs to be continuously discharged, which causes a lot ...
