Angel Super Alcohol Active Dry Yeast (starch base)

 

I. Product introduction

The product is made of specifically selected high-quality alcohol yeast strains with compound nutrient agents, and is applicable when adopt corn, wheat and cassava as raw materials for alcohol high gravity fermentation. This product is suitable for alcohol and fuel ethanol production in the method of fermentation with the characteristics of strong reproductive ability, high fermentation speed, high tolerance to high ethanol concentration, etc. The product can shorten the fermentation time, and realize the fermentation of alcohol with high concentration

 

Applicable raw materials: corn, cassava, wheat and other starch bearing materials.

 

II. Product characteristics:

1.Ethanol tolerance: ≤18%(v/v)

2.Temperature tolerance: 80°F-108°F(28-42℃), the optimal fermentation temperature is 90°F-93°F (32-34℃)

3. pH tolerance: 3.5-5.5, the optimal fermentation pH is 4.5-5.5

4. The cycle of alcohol fermentation is appropriately shortened: 60-65 hours for batch fermentation, 55-60 hours for continuous fermentation

 

Brief Introduction

 

Angel Yeast Co., Ltd, founded in 1986, is a high-tech listed company dedicated to the research & development and mass production of yeast products and its derivatives. Upholding the motto of “Natural, Nutrient and Healthy”, the company commits itself to becoming a “large international and specialized yeast company”

 

 

 

Angel provides its natural, safe and high quality brewing yeast and technical services for the global market. The products undergo the strict control on the material and processing. The company provides the appropriate products and services for fuel ethanol, alcohol, wine, beer, and other distilling and brewing liquor, and develop the products or technical support to satisfy the unique requirements of customers.

 

 

 

Angel brewing and distilling products include: super alcohol active dry yeast, thermal-tolerant alcohol active dry yeast, active dry wine yeast, active dry brewer yeast, and sugar leaven.

 

 

Advantages of thick mass fermentation

1.Reduce energy consumption. Upon the verification, the alcohol content is increased by 10%, and the steam consumption is reduced by about 300kg

2. Reduce process water consumption, reduce 1-2 tons for each ton of alcohol, and reduce waste water treatment cost.

3. Improve equipment efficiency

 

III. Index

Item	Index
Moisture %           ≤	6.5
The   rate of living   yeast cell %         ≥	80.0
Total   yeast Count(108/g) ≥	200
Salmonella	Negative

 

 

IV. Application:

Direct add yeast in fermentation tank (batch fermentation):

Each liter of mash is added with 0.25-0.3g of dry yeast, and the initial cell count of fermentation mash reaches 5 million /ml.

Characteristics:

Simple operation, simplified flow

Favorable for stable control

The probability of bacterial infection is reduced

 

Propagation in culture tank:

When the equipment and process allow, on the basis of strictly controlling bacterial infection and providing the yeast with the required nutrition, inoculate to ferment after culturing for 8-10 hours, so as to relatively reduce the yeast consumption. In consideration of the aging and degeneration of yeast in the culture process, the optimal inoculation replacement cycle shall be 72 hours.

Nutrition required by yeast culture:

Nitrogen source, phosphor source, magnesium ion, zinc ion, etc.

 

The optimal yeast culture method:

Sugar degree<13%Bx

Temperature 86°F-90°F(30-32℃)

PH 4.0-4.5

Culture time 8-12 hours

Appropriately add nutrition

Mature yeast index: with the cell count of 250million/ml, budding >10%

 

V. Specification: 5kg*2/carton

VI. Storage condition and shelf life:

Vacuum aluminum foil packaging, store in low temperature and dry place, with the shelf life of 12 months.
