Problems solved by technology

However, it also has the disadvantage of easily clogging the candle filter. It is necessary to clean the clogged filter rod from time to time, so the whole filtration time is still very long. This is mainly because the soy sauce raw material itself has a lot of particulate matter, which is easy to frequently block the candle filter. filter stick

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 Shown, a kind of soy sauce filtering process, take filtering 80t soy sauce raw material as example, adopt candle type filter, comprise the following steps:

[0022] 1) Lower the soil: Pour 80t of soy sauce raw material and the first diatomite into a mixing tank and stir for a period of time, then let it settle and layer, and then obtain the supernatant and the sediment layer, wherein the weight of the first diatomite is The weight of the soy sauce stock solution is 1.5‰, the stirring time is 0.5 to 1 hour, the standing precipitation and layering time is 6 hours, the wet volume of the first diatomite is 3.0L / Kg, and the wet volume of the present invention is Diatomaceous earth absorbs the volume of pure water, and the first diatomaceous earth fully absorbs the impurities in the soy sauce raw material, reducing the phenomenon of clogging the filte...

Abstract

The invention discloses a filtering process for soy. Compared with a conventional filtering process, the step of soil feeding is added in the invention; and with the step, a part of particles can be adsorbed in advance, and particles in a raw material for soy are greatly reduced, so subsequent coating and filtering operation are facilitated, the particles in the raw material for soy are preventedfrom blocking a filtering rod, filtering time is reduced while original filtering effect is achieved, and filtering cost is lowered; and a variety of diatomite with different wet volumes is cooperatively used so as to protect the filtering rod from obstruction, and filtering effect is optimized.

Description

technical field [0001] The invention relates to the technical field of condiment processing, in particular to a soy sauce filtering process. Background technique [0002] At present, many soy sauce companies use candle filter and diatomite filter technology. The candle filter is equipped with a filter rod, and diatomite is coated on the filter rod, and the micropores on the diatomite absorb the content of soy sauce. Particles, the soy sauce processed by this filtering technology has a good filtering effect, such as the Chinese invention patent whose publication number is CN103181541A: a kind of filtering method for soy sauce, which has the following advantages: 1) in ensuring the total nitrogen of soy sauce and amino acid in each index Under the premise of minimizing the loss of nitrogen, salt, sugar content, pigment and other ingredients, it can reduce the precipitation of soy sauce; 2) The coating time is short and the production efficiency is high. However, it also has t...
