High humidity vinegar residue resource processing method

Abstract

The invention discloses a method for processing high humidity vinegar grain resources, which is characterized in that: humid vinegar grains which are pressed and dehydrated enter directly to an incinerator to incinerate; the incinerator is ignited and burned with external energy source; the humid vinegar grains are dried by exhaust fume which is generated by incinerating so that a drying system has enough heat energy to dry enough dry vinegar grains; the dry vinegar grains are fed into the incinerator to incinerate; an igniting system is closed; the humid vinegar grains are dried by smoke gas which is generated by incinerating; and circulation is formed. The invention adopts the exhaust fume of a waste heat boiler to dry the vinegar grains which are pressed. The method for processing high humidity vinegar grains resources has the advantages of turning a waste into a treasure, shortening processing time, and improving greatly processing efficiency without influence of the marketing, is unnecessary to consume new energy source, saves the energy source, removes stink and acidity of the vinegar grains, reduces quantity of air volume, reduces quantity of processing quantity with environmental protection, also provides surplus energy and chemical substances, solves the problem of high salinity, and turns a waste into a treasure.

Description

technical field [0001] The invention relates to the utilization of waste residues in the technical field of food preparation, in particular to a method for recycling high-humidity vinegar residues in the vinegar production process. Background technique [0002] Vinegar grains are wastes left after making vinegar from organic raw materials such as glutinous rice, rice, and bran. In the vinegar industry, there is a large amount of vinegar grains produced every day, but vinegar grains are acidic organic matter, which has low calorific value, high moisture content, high salinity, emits a lot of odor, takes up a lot of space and resources, and is highly acidic. Decomposition is slow, directly produces serious pollution to the environment and other characteristics, because of these characteristics, the processing of vinegar tank is quite difficult, so the problem of processing vinegar residues has become a major problem in the vinegar industry. For this reason, many research unit...

Problems solved by technology

Moreover, the fertilizer made from vinegar grains is highly acidic and has high salinity, which can easily destroy the acid-base parallelism on the surface and increase the salinity of the soil, which will eventually affect the growth of crops; on the other hand, vinegar grains are mixed with other raw materials to make feed , such as the high methionine biological feed protein and preparation method provided by Chinese patent 98124959.0, there is also the problem of low consumption of vinegar grains, only about 10%, the process is also complicated, and currently the products processed with vinegar grains as raw materials are sold in the market It has not been opened yet, it is difficult to promote, and is restricted by market factors. Therefore, it is difficult to improve its processing capacity and processing efficiency

In addition, the vinegar residues are directly processed, such as adding some fuels with high calorific value (coal, gasoline, etc.) for direct incineration, and directly burying the vinegar residues, etc. These methods not only cause huge waste of resources, pollute the environment, but also increase the salinity of the ground surface , the cost is high, and it also consumes new energy and takes up huge space resources
