Abstract

A distiller's yeast "Tongfengqu" is prepared from rice husk as main raw material, wheat brain, corn flour and fresh distiller's grains through culture of bacterial strain, ventilation culture of distiller's yeast, etc .and features saving grains, low cost, high output rate of wine (50-55%).

Description

A kind of ventilating distiller's yeast and preparation technology thereof

The invention belongs to food brewing industry category, refer more particularly to the brew of distiller's yeast.

The distiller's yeast of liquor industry requires than higher starting material, need with a large amount of rice, wheat bran and corn, the quantity that consumes grain is very big, especially there is numerous little breweries the present various places of China, because technology and equipment aspect fall behind, and reason such as mismanagement, the yield of liquor is relatively low, and this is another big waste to using grain undoubtedly.

The objective of the invention is to adopt the main raw material of rice husk, and be equipped with corresponding wheat bran, Semen Maydis powder and the bright poor distiller's yeast of making, save food, reduce cost with realization as distiller's yeast.

Main technique prescription of the present invention is: rice husk 45--60, wheat bran 10--20, Semen Maydis powder 10--15, bright poor 20--30; The water that adds 45--60.More than be measure unit with weight.

Technological process of the present invention is:

One, culture of strains

1, cultivation:

A, bacterial classification adopt aspergillus tubigensis (Ha Noi is bent in vain) or other bacterial classifications all can

B, carry out test tube and cultivate

C, culture medium prescription are wort 12--13BX, acidity 0.2--0.25,

D, culture condition: culture temperature is 28--30 ℃, and incubation time is

4--5 days

2, bottle device enlarged culturing: culture temperature is 28--30 ℃, and incubation time is

5--7 days

3, the sort of quyi:

A, use bed formula are cultivated

B, culture temperature 28--32 ℃, incubation time is 4-5 days

Two, the ventilation of distiller's yeast is cultivated

A, the rice husk of will preparing burden, wheat bran, Semen Maydis powder, aquatic foods are pickled with grains or in wine, prepare in proportion, mix thoroughly;

Add a certain proportion of water before b, the steaming material, material moistening 30-60 minute, to beat except that luming with raising the slag machine then, dress pot back atmospheric cooking 45-60 minute carries out gelatinization;

Be cooled to the 37-40 degree after c, the gelatinization and inoculate, sort of quyi consumption is the 0.4-0.6% of raw material, earlier the part material and the sort of quyi is puddled during inoculation, mixes thoroughly with whole bent material then;

D, the song material that will mix thoroughly are packed in the groove, and charging thickness is advisable with 20-25 centimetre, and material will shakeout, and the product temperature of bent material will be controlled at about 30 degree;

E, tankage begin to be stationary phase by 8 hours, and behind the tankage 4 hours, logical once indoor wind was given 4-5 minute wind time, will the product temperature control at the 30-34 degree;

Be to cultivate mid-term in 8-16 hour behind f, the tankage, when the product temperature rises to 36 when spending, promptly between open close indoor wind, the product temperature of making remains on the 33-36 degree;

G, tankage are cultivated and were the later stage cultivation in 16-28 hour, and the later stage requires continuous ventilating, and control product temperature remains on the 38-45 degree;

H, management phase are for cultivating after 28 hours until going out the room, and this stage requires continuous ventilating, keeps the product temperature between the 35-37 degree, humidity discharging as far as possible reduces indoor wetness, after 29-30 hour, can open door and window, with outdoor dry-air blast ventilation humidity discharging, the backsight growing state went out the room in 34 hours.

The quality standard of finished product song of the present invention is:

Saccharogenic power: more than 700 units, acidity: about 2.0,

Moisture content: below 30%, color: yellow or yellow-white

Quality standard by the finished wine of the bent brew of finished product of the present invention is:

Water white transparency does not have precipitation and suspended substance;

Having ethyl acetate is main fragrance;

Giving off a strong fragrance is pure and mild, and it is refreshing clean that flavor is coordinated tail.

Embodiments of the invention as mentioned above.

Advantage of the present invention is:

1, liquor ratio of raw material reaches 50-55% (calculating with 60 degree wine);

2, the bent vinosity road made of this distiller's yeast belongs to Luzhou-flavor;

3, be main raw material owing to having adopted grain dead meal rice husk, the cost of wine is greatly reduced;

4, processing method of the present invention is fit to large, medium and small type brewery;

5, this technology is simple and convenient and easy to study, is convenient to the technician and grasps.
