SU403721A1 - METHOD FOR PREPARING STARCH RAW MATERIALS FOR ALCOHOLIC FRICTION - Google Patents

Description

one

The invention relates to the alcohol industry and can be used in distilleries processing starch and containing raw materials.

A known method for preparing starchy raw material is by boiling it, cooling it to 56-58 ° C and continuously introducing malt or mold fungi enzymatic preparations (deep or on top of a culture) into dissolved and cooled starch.

However, the known method has a low rate of enzymatic hydrolysis of starch, a high consumption of malt or enzyme preparations, and is characterized by incomplete saccharification of starch and associated slow digestion of the saccharified mass, which leads to a decrease in the yield of alcohol.

The purpose of the invention is to speed up the process, reduce the consumption of saccharification, their weight, and increase the alcohol yield.

This is achieved by the fact that during saccharification, the continuous circulation of the saccharified mass in a closed circulation circuit through an inert filler, which is in a fluidized state, and the selection of the mass for cooling and fermentation in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in an amount equal to the amount of starch-containing raw material and saccharified and cooled and fermented in a quantity equal to the amount of starch-containing raw materials and saccharified and cooled and fermented in a quantity equal to the amount of starch-containing raw materials and saccharified and cooled and fermented in a quantity equal to the amount of starch-containing raw materials and saccharified and starch-free their substances entering the saccharification.

Circulation by Maccbi saccharification through an inert filler is carried out for 5-15 minutes at a speed of 0.1-0.8 m / s, depending on the properties of the polycarbonate. The proposed method is carried out as follows.

Raw materials are boiled under pressure, cooled to 57 ° C and set into a continuous stream.

dissolved starch saccharifying agents - malt or mold fungus enzymes. The osucharn mass from the main saccharifier is injected into the fluidized bed reactor.

inert material, for example balls of polyethylene. The saccharified mass rate in the free cross section of the reactor must be higher than the first critical liquefaction rate and lower than the fill rate of the filler (0.1 -

0.8 m / s).

The saccharified mass circulates through a closed cycle axial saccharifier-reactor. The total mass in the reactor should be 5-15 minutes. Part saccharified

the masses from the reactor are sent for cooling and further for digestion. The amount of the selected mass should be equal to the amount of the starch-containing raw material solution and saccharifying agents that come

In the main Osa.Harivatel.

The example illustrates the implementation of the proposed method.

Wheat is boiled under pressure of 7–8 atm in a continuously operating tubular diaphragmatic pot (Mirotsk scheme).

The uncoupled mass continuously enters the saccharifier in an amount of 5. The mass in the saccharifier contains 18% CB, is cooled to 57 ° C. Malted milk is continuously dispensed into the sugar extractor.

The malt is consumed grain in the amount of 10-13% by weight of starch, after which the sugar is saccharified. The saccharified mass from the main saccharifier is injected into the reactor with fluidized material by a centrifugal pump, for example, a layer of polyethylene balls with a diameter of 6 mm. The velocity of the saccharified mass in the free section of the apparatus (a cylindrical vessel with a diameter of 150 mm and a height of 5000 mm) is 0.5 m / s. 0.5 saccharified mass passes through the reactor. In an hour, 5 m of the mass is saccharified. Ve part of the mass is directed to cooling and fermentation, and 3/6 is returned to the main desiccant.

The volume of the main saccharifier is calculated on a 15-minute supply of saccharified mass, i.e. in this case it is equal to 1.25 m.
