Abstract

FIELD: alcohol industry.

SUBSTANCE: invention refers to alcohol and feed industry and can be used in waste recycling of distillery stillage and starch-treacle production. Method consists in adding vegetable raw materials into distillery stillage. The vegetable raw material is corn core to the amount of 10-15%, mix the mixture and in two-three days add clay - alanyte to the amount of 2-3% of total mixture volume, then mixture is accurately mixed.

EFFECT: method allows diminishing acidity of the prepared feed product.

Description

The invention relates to the alcohol and feed industry and may find application in the disposal of waste - alcohol stillage and starch and syrup production.

A known method of utilization of alcohol stillage with a clay-irlite reagent containing iron and aluminum oxides interacting with sulfuric acid, present in the stillage with subsequent preparation of the feed product (patent No. 2204591, IPC 7 C12F 3/10, published 2003).

The disadvantage of this method is that large particles of irlite are not sufficiently dissolved in the bard, preserving the heavy metals, sulfides and chlorides containing it.

The closest technical solution is a method in which clay-tereklite is used to clean the wastes of the alcohol industry with the subsequent introduction of soy flour (patent No. 2261620, published April 27, 2005, IPC A23K 1/06, C12F 3/10, C01B 33/4).

The technical result is a reduction in the cost of disposal and acidity of the prepared product.

The technical solution of the claimed object is that for cleaning waste from the alcohol industry use corn cobs in the amount of 10-15%, mix the mixture and after 2-3 days add clay-alanite in the amount of 2-3% of the total volume of the mixture, thoroughly mix the whole mass.

The method is as follows.

Corn coats - waste of starch and syrup production (1 kg of corn contains 200 kg of rods) have high solubility, absorption, neutral reaction of the medium (pH 6.9-7.1), the absence of resins, wax, the complete absence of heavy metals and complex trace elements. All these indicators characterize corn cobs as ideal organic carriers. Dissolving in alcohol bard, they enrich it with a complex of nutrients, while softening, which does not require preliminary grinding, as in the prototype (soy flour).

Corn cobs contain 41.7% cellulose, 37.2% chemicellulose, 8% lignin, 0.08% fat, 1.75% protein and BEV 61.7% (coarse fraction). When grinding, the protein content in the stalks rises to 4.31%, BEV - 65.1%. In the proposed parameters, they sufficiently enrich the recycled vinasse with nutrients.

Within 2-3 days, the cobs dissolve in the distillery stillage, enriching it with a complex of nutrients, while softening.

Alanite contains more than 30% calcium, which ensures a decrease in the acidity of bards. The introduction of alanite in a mixture of stillage and cobs provides a complete high-quality feed.

Example 1. In an alcohol bard (pH 4.8) in an amount of 50 l was added 5 kg of corn cobs, mixing the mixture. After 2 days, an additional 2.0 kg of alanite was added, thoroughly mixing the entire mass.

With stirring, the cobs were crushed, and the solution itself reduced acidity to pH 5.6.

Example 2. In the distillery distillery waste alcohol production in the amount of 100 l was introduced 15 kg of corn cobs. After 3 days, an additional 3 kg of alanite was added. The resulting mixture was used as a feed product for fattening gobies.

Comparing the indicators of known tereclite and alanite, a high concentration of CaO, which affects the acidity of the utilized stillage, should be noted (Table 1).

Table 1 The content of chemicals reagents tereclite and alanite,% component tereklit alanite SiO ₂ 56-57 51-53 Al ₂ O ₃ 20-21 16-17 Fe ₂ O ₃ 4.03 5-6 CaO 0.60 30-33 K ₂ O 2.90 0,07 P ₂ O 0.1 0.38 MnO 0.05 0.04 SO ₃ 3.26 0.98 MgO 2.25 1,6 Na ₂ O 0.91 0.92 pH 5.1 8.64

The data in the table indicate that alanite is richer in calcium, phosphorus, iron, and has an alkaline reaction.

The feed mixture from the obtained utilized products is characterized by high feed strengths (Table 2).

The results of the test variants indicate that the proposed feed product from recycled waste contains the maximum amount of metabolic energy (4.2 MJ per 1 kg of dry matter), 28-29% protein, a reduced amount of fiber 15-16% and 22-22% of mineral substances. Thus, utilizing food industry waste, you can get high-quality animal feed.
