- the present invention relates to an acid cleaning process in the brewing industry, and in particular an improved acid cleaning process of the various materials used for the manufacture of beer and other related fermented beverages.
- this step consists in mixing the cereals (barley, malt (germinated barley), wheat, rice) with hot water (with temperature levels of 40 0 C to 100 0 C) and aromatics such as as hops and possibly various and varied spices. This stage makes it possible to extract cereals sugars and proteins to form what is called must;
- fermentation the clarified must, after cooling is introduced into the fermenter (usually a cylindro-conical reactor) called FVT.
- the yeast is added and the whole macerates for three to seven days at a temperature of 6 to 10 ° C. This step converts glucose and sugars into carbon dioxide and ethanol.
- the guard at the end of the fermentation, the mixture is shocked cold at 3 ° C to coagulate the yeasts and proteins. This step takes place either in the fermenter or in another tank. The resulting beer is matured in the guard reactor and clarified.
- the beer is packaged in barrels or in bottles, or even cans.
- step 3 we often observe the formation of a crown of bitter (or crown of yeast, "yeast ring” in English) at the gas phase / liquid phase interface.
- Bitter is mainly composed of organic insolubles: yeast residue, cell wall, insoluble sugars.
- fermentor bottom and on its walls form “beer stones”("beerstones” in English), which consist mainly of calcium oxalate and various organic materials.
- the fermenter is therefore commonly soiled by two types of very distinct soils: organic dirt (mostly bitter crown) and inorganic soils (mainly "beer stones”).
- an essential aspect in the preparation of beer, or other related fermented beverages is to have drums, containers, fermenters, pipes and other devices for transporting or staying liquids used in the preparation of said beer and other fermented beverages, which are absolutely clean and in particular free of any trace of organic and inorganic soiling. Indeed, such fouling could cause the presence and growth of bacteria or any other elements harmful to the prepared products, or even make them unfit for consumption.
- each reactor is washed either in a basic medium or in an acidic medium according to the step concerned for the preparation of the beer.
- the washing of the various elements of the installation used for the preparation of beer is usually carried out according to the following steps:
- A) brewing reactor basic washing with sodium hydroxide
- Pre-cleaning called “one-way” washing with clean water (removal of 10% of the soil), or in the presence of dilute soda (removal of 80-90% of the soil) in the form of Fast "shot", which allows a better elimination of soiling.
- Sodium hydroxide can not be used in large quantities because the fermentation tank contains carbon dioxide that may react with sodium hydroxide which could cause the vessel to collapse by depression;
- Cleaning with phosphoric acid generally at 1.5% by volume of a 56% by weight solution of phosphoric acid); and
- washing steps 2 and 3 are carried out successively with the aid of two different acids, each being effective for the removal of a type of soiling:
- C) guard this generally has less soil than the fermentor and in particular little or no bitter crown; therefore, most often a simple cleaning with water followed by cleaning with sulfuric acid + biocide mixture indicated above.
- the barrels are cleaned hot (typically about 80 0 C) with phosphoric acid, the sulfuric acid being too corrosive at this temperature, as indicated supra.
- a first object of the present invention to provide a method of cleaning facilities used in the manufacture and storage of beer simpler and faster than those currently used.
- Another object of the present invention is to provide a simple and effective method for both effective cleaning of "beer stones” and bitter crowns.
- Another objective is to propose a method of cleaning the facilities used in the preparation and storage of beer and other fermented drinks, by means of a single formulation allowing removal of all types of soiling, including "beer stones” and bitter crowns.
- an alkanesulfonic acid-based formulation makes it possible to avoid the use of several cleaning formulations, such as a phosphoric acid-based formulation and a sulfuric acid-based formulation.
- the use of an alkanesulfonic acid-based formulation may also make it possible to avoid several successive washing operations and also several intermediate rinses.
- the benefits are mainly a saving of time, costs, productivity, energy, and a decrease in the number of cleaning chemicals present on the manufacturing site.
- the phosphoric acid usually used is released in the form of phosphates, which can harm the environment, and increasingly stringent environmental standards aim to outlaw phosphate releases.
- a first object of the invention consists of a cleaning process of an installation used in the preparation of beer, or other related fermented beverages, comprising the steps of: a) optional prewashing of the installation; b) washing the plant by circulating in said plant an effective amount of a formulation comprising at least one alkanesulfonic acid; and c) rinsing the installation by circulation of a rinsing solution.
- the method of the invention allows on the one hand to reduce the number of cleaning steps, and on the other hand to reduce the number of acid formulations used, two (phosphoric acid and sulfuric acid) to a single cleaning formulation of soiling.
- the formulation used in the process of the invention being less corrosive than sulfuric acid, it can be used for cleaning hot barrels.
