摘要:
Wort suitable for making e.g. beer is produced by extracting ground chit malt with a mixture of hot water and malt, the proportion of malt being 10 to 40% by weight on a solids basis of the dry weight of the mixture of ground chit malt and malt.

The present disclosure provides methods for treating one or more grains in an ethanol plant or alcohol brewery, methods of drying, cooling, disease control of dried distillers grains with soluble (DDG), barley, or brewer's spent grain (BSG), and a system for treating one or more grains in an ethanol plant or alcohol brewery by these disclosed methods.
摘要:
A single apparatus for preparing brewing malt in three steps, namely steeping, germinating and drying. A horizontal rotary annular perforated rack arranged in a cylindrical trough is charged with the material to be treated and while placed on the rotating rack is firstly steeped in water introduced into the trough below the rack. After the water has been discharged, the germinating step is performed by introducing air conveyed by a fan into the space between the rack and the bottom of the trough and upwardly through the material, which latter is turned by a horizontal series of vertically arranged turning worms which as a unit may be horizontally moved into the material on the rotating rack, the unit of worms being vertically movable into the layer of material and again outwardly therefrom. During the final drying step, the same fan is used to circulate heated air through the material on the rotating rack, and the dried material then discharged from the rack by a conveyor which may be lowered into the material on the rack. The material is then discharged into a worm conveyor leading to a discharge pipe. As conveyor may serve an endless conveyor with buckets which scoop the material from the rack.
摘要:
A method of treating malting grain, in which the grian is subjected to a water restriction stress after commencement of germination under normal conditions. The grain is germinated in a grain-germinating environment but before completion of germination is subjected to said water-restriction stress by reducing the amount of water available to the grain within said environment. This is done for at least one time-interval sufficient to modify, as compared with normally-germinated grain, at least one of the following parameters, namely: (i) the amount of soluble sugars in a hot water extract; (ii) the alpha-amylase level; (iii) the degree of root and shoot growth; (iv) the total nitrogen content and the soluble nitrogen ratio; and/or (v) the diastatic power; as determined in the germinated and thus-treated grain. Preferably the water restriction stress is imparted by lowering the relative humiditity of air flowing around the grain within a germination environment to below 95%. The invention also relates to grain treated by such methods and malt produced from such grain.
摘要:
During the kilning of germinated barley in the course of a malting operation nitrosamines are usually formed and ultimately these end up in beer obtained from such malt. It has been found that such formation of nitrosamines can be suppressed even in the absence of sulphur dioxide when the germinated barley is treated with a solution or dispersion of saccharides before it is kilned.
摘要:
A process of malting for the production of acid malt involving subjecting grain having a low percentage of potential extract (less than 75 percent) to oxygen-free conditions at chitting (rootlet emergence) or at an early stage after chitting. The period of exposure to these conditions is at least 2 days at temperatures of 10* C. to 36* C. and the preferred moisture content of the grain is high (35 to 50 percent). Drying temperatures are low (i.e., below about 55* C.) if normal colored acid malt is needed, but a novel and very highly colored dried acid malt may be obtained if drying is carried on at temperatures above 80* C.
