Process for preparing soybean soy sauce by solar geothermal source

Abstract

The invention provides a process for preparing soybean sauce by using a solar energy terrestrial heat source. The process comprises the steps: 1, washing a material by adopting flowing warm water; 2, soaking the material by adopting the flowing warm water; 3, steaming the material by focusing solar energy; 4, mixing and inoculating; 5, warming by adopting the solar energy to make a starter; 6, warming by adopting the solar energy to make fermented sauce; 7, sprinkling oil; 8, settling; and 9, blending and sterilizing. In the steps, required heat sources are provided by mainly adopting a manner of using the solar energy as a main raw material and a terrestrial heat source as an auxiliary material; water used in the steps 1 and 2 is treated by adopting a reverse osmosis process to obtain pure water, and the treated pure water is repeatedly used for washing and soaking the raw material and cleaning environment, equipment and a tool. The process has the advantages of pure taste of a product, energy and water saving, environmental friendliness, cost saving, simplicity in operation, and convenience in popularization.

Description

technical field [0001] The invention relates to a food preparation process, in particular to a process for preparing soybean soy sauce from a solar geothermal source. Background technique [0002] In the current process of preparing soybean soy sauce, the washing step adopts cold water washing, which is not as effective as warm water; and there will always be some unfavorable ingredients such as pesticides attached to the elutriation; and the sewage discharge after washing wastes water resources and increases the impact on the environment. pollute. Foaming materials, cold water foaming is time-consuming, stagnant water foaming materials will produce rancid substances; sewage discharge wastes water resources and increases environmental pollution. Cooking material, the energy used in this process is mainly coal and electricity, which consumes energy; produces a lot of dust and smoke, pollutes the environment; boiler equipment, personnel, and fuel require a lot of money. Koji...

[0002] In the current process of preparing soybean soy sauce, the washing step adopts cold water washing, which is not as effective as warm water; and there will always be some unfavorable ingredients such as pesticides attached to the elutriation; and the sewage discharge after washing wastes water resources and increases the impact on the environment. Pollution

Foaming materials, cold water foaming time-consuming, stagnant water foaming materials will produce rancid substances; sewage discharge wastes water resources and increases environmental pollution

Cooking material, the energy used in this process is mainly coal and electricity, which consumes energy; produces a lot of dust and smoke, pollutes the environment; boiler equipment, personnel, and fuel require a lot of money

Koji making, koji making in the koji pool is not conducive to dust prevention, anti-fly insects; it is not easy to control temperature; it is inconvenient to operate

Fermentation of fermented grains, heating and fermenting through the circulating water of the fermentation tank or loading the large tank with sunlight to ferment the fermented grains is not conducive to preventing dust and flies; it is not easy to control the temperature; it is inconvenient to operate; it is inconvenient to maintain the equipment
