Embodiment 1

[0028] 1. Broken red dates

[0029] Pour the defective dried red dates into the selection table, manually remove the moldy and rotten fruits, pick out the stones, metals and other sundries that damage the processing machinery and affect the processing in the fruit, and pour the removed red dates into the chain In the belt-type bubbling cleaning tank, remove the leaves and wooden branches floating on the liquid surface, fully clean the soil, sand and other unclean substances on the surface of the husk, and crush the husk with a stainless steel hammer mill until the diameter of the broken particles is less than 10mm.

[0030] 2. Cooking

[0031] Put the crushed dried red dates into the soaking pool, add tap water of the same quality as the dried red dates, and soak them at room temperature for 4 hours to make the dried red dates fully absorb water. The elevator is added to the vertical steam cooking tank with a conical bottom, sealed, and steam is introduced to keep the steam p...

Embodiment 2

[0042] 1. Broken red dates

[0043] Pour the defective fresh red dates on the selection table, manually remove the moldy and rotten fruits, pick out the stones, metals and other sundries that damage the processing machinery and affect the processing in the fruit, and pour the cleaned red dates into the chain In the belt-type bubbling cleaning tank, remove the leaves and wooden branches floating on the liquid surface, fully clean the soil, sand and other unclean substances on the surface of the husk, and crush the husk with a stainless steel hammer mill until the diameter of the broken particles is less than 10mm.

[0044] 2. Cooking

[0045] Put the crushed fresh red dates into a vertical steam cooking tank with a conical bottom with a bucket elevator, seal it, and feed steam to keep the steam pressure in the tank at 0-0.05MPa, and wait until the temperature of the material center in the tank rises Start timing when the temperature is 100°C, and stop steaming after 30 minutes...

Abstract

The invention discloses a method for producing edible alcohol by fermenting thick mash of defective red dates at a high temperature. According to the advantages of high sugar content of defective red dates, defective red dates are taken as raw materials, by virtue of high-temperature alcohol-resistant Schizosaccharomyces pombe, and the thick mash of red dates is subjected to high-temperature alcoholic fermentation to obtain red dates edible alcohol dates. According to the method, the conversion rate from carbohydrates in red dates to ethanol reaches above 80%, and the produced red dates edible alcohol is in line with hygienic standards of national edible alcohol.

Description

technical field [0001] The invention belongs to the technical field of food fermentation, and in particular relates to a method for producing edible alcohol by high-temperature fermentation of residual and sub-red dates with thick mash. Background technique [0002] Jujube is one of people's favorite fruits. Red dates are native to China, and 90% of the world's red dates come from China. In recent years, with the implementation of the policy of returning farmland to forests in my country, jujube has further become an ecological and economic tree species in the Yellow River Basin, and the cultivated area and output have increased sharply. In addition to fresh red dates, the products sold on the market are mainly dried products. After jujube farmers and enterprises sell dry products with good appearance and quality, there will be a large number of defective red dates that cannot be sold every year. The so-called defective red dates mainly refer to cracked dates, dropped date...
