Problems solved by technology

Due to the fact that the sediment takes a long time to settle, a large number of settling tanks and settling time are required, the production efficiency is low, and the recovery rate of soy sauce from the sediment is low; and the content of insoluble matter in the sediment is high, the filtration accuracy of the press is low, and the soy sauce squeezed out is insoluble High content of substances, cannot be made into high-end soy sauce, can only be used to make low-end soy sauce

Embodiment 1

[0023] (1) Filter the soy sauce sediment through a 60-mesh sieve to obtain the filtrate;

[0024] (2) The above-mentioned filtrate is processed by circulating filtration with a hollow fiber ultrafiltration membrane to obtain a clear liquid and a concentrated liquid, and the gained clear liquid can be recycled for making soy sauce. The specific operating conditions of this step are shown in the following table:

[0025]

[0026]

[0027] ※ Concentration ratio = Feed liquid input amount / (Feed liquid input amount - Filtrate amount)

[0028] The resulting clear liquid can be recycled for making soy sauce, and its parameter changes are shown in the following table:

[0029]

[0030] (3) The above-mentioned hollow fiber ultrafiltration membrane can be reused after being washed with water, the first cleaning solution and the second cleaning solution successively at a temperature of 30°C, wherein the first cleaning solution includes 1% NaOH and 1000ppm NaClO, and the solven...

Abstract

The invention discloses a soy sauce sediment treatment method, which comprises the steps of: (1) filtering soy sauce sediment by a sieve of 60-70 meshes to obtain a filtered solution; (2) conducting circulating filtration treatment on the filtered solution with a hollow fiber ultrafiltration membrane to obtain a clear solution and a concentrated solution with a concentration multiple of 4.5-4.95; and (3) cleaning the hollow fiber ultrafiltration membrane at 20-35DEG C with water, a first cleaning fluid and a second cleaning fluid in order for reuse. The method provided by the invention adopts filtration membrane to directly filter the soy sauce sediment, has no need of a settlement step, saves a lot of settling tanks and settling time, greatly improves the production efficiency, and saves a lot of production cost. The recovery rate of sediment soy sauce can reach about 80%, the clear solution suspended matters and bacterial colonies that are filtered out are very low in number, basically zero, amino acid and other flavor substances therein are retained, the flavor has no loss, so that the sediment soy sauce can be used for production of high-end soy sauce and has obvious recovery economic benefits.

Description

technical field [0001] The invention belongs to the technical field of soy sauce processing, and in particular relates to a processing method for soy sauce residue. Background technique [0002] In the prior art, the raw materials for the production of soy sauce undergo koji making, koji making, mash making, and fermentation to produce raw soy sauce. After the raw soy sauce is pressed, the soy sauce still contains a large amount of suspended matter, which needs to be settled. The clear liquid is directly prepared with auxiliary materials, sterilized, and packed into finished soy sauce. The sediment after sedimentation contains a large amount of insoluble impurities, so it needs to be sedimented, and the supernatant after sedimentation is squeezed, and the supernatant after sedimentation is prepared for auxiliary materials, sterilized, and packaged as a finished product. Due to the fact that the sediment takes a long time to settle, a large number of settling tanks and settl...
