Problems solved by technology

High-temperature hot air drying consumes a lot of energy, and coal-fired boilers are needed to provide thermal energy to dry distiller's grains. In this process, not only coal combustion produces a large amount of gas and dust pollution, but also because the waste distiller's grains contain a large amount of acids, esters, aldehydes, and alcohols. In addition to water, there are a large number of acidic organic components in the escape of the drying process, which seriously pollutes the atmosphere and the surrounding environment. It is a high-energy-consumption and high-pollution technology; mechanical pressing / centrifugal drying relies on mechanical work to separate free water and Interstitial water, but it is difficult to separate the capillary bound water in the material, and it is impossible to separate the surface adsorption water and internal water in the material, so the water content of the final dehydration product is still greater than 25%-40%, and the dehydration effect is not obvious. At the same time, the process capacity Low, high energy consumption per unit capacity, severe mechanical wear, poor continuous productivity
At present, the most ideal treatment process on the market is the combination of these two processes, and some companies have proposed to use part of the dried distiller's grains to participate in boiler combustion, and the circulating high-temperature flue gas generated to participate in drying, thereby reducing the amount of coal consumption, but it is still not possible Get rid of the major defects of high energy consumption and secondary pollution to the environment during the treatment process
At the same time, due to the large discontinuity in the brewing production cycle of liquor enterprises, the current processing technology has poor adaptability to the brewing production cycle, and the production waste increases

Abstract

The invention discloses a novel pollution-free drying treatment process for waste vinasse generated by brewing, relating to a treatment process for waste vinasse generated by brewing. The process comprises the following process steps of: material deacidification treatment, acid-base detection, strain inoculating and stirring, inoculating, temperature raising treatment before a material pile, material pile mixed culture fermentation and precipitation treatment, treatment indication detection, turn / blowing treatment, fermentation process requirement detection, property stability treatment, property requirement detection and packaging and storing. A production mode more suitable for a wine production enterprise is developed in the invention; the novel pollution-free drying treatment process for waste vinasse generated by brewing has larger production elasticity and adopts a brand new treatment flow with low energy consumption and low pollution to finish the drying treatment flow on waste vinasse; and process parameters can be regulated according to the purpose of the following dried vinasse, thereby high-quality raw material is provided.

Description

Technical field: [0001] The invention relates to a process for treating waste distiller's grains from brewing, in particular to a novel pollution-free drying process for waste distiller's grains in winemaking. Background technique: [0002] At present, domestic liquor companies produce a large amount of waste distiller's grains that need to be disposed of. Because the waste distiller's grains have high acidity (PH<3), high moisture content (>70%), and are easily corrupted, they are not conducive to transportation and storage. If the waste distiller's grains are allowed to accumulate without If the waste distiller's grains are not processed in time, the waste distiller's grains will quickly rot, producing a large amount of toxic and harmful acid water to pollute the surrounding soil, affecting the soil quality of the surrounding farmland, releasing a large amount of odor to pollute the air, and easy to breed mosquitoes and harmful bacteria. [0003] Distiller's grains c...
