摘要:
A method for treating a fluid is provided using a particulate material in the form of a deposited layer having an upstream side and a downstream side wherein a flow of the fluid is directed through the deposited layer from the upstream to the downstream side at a first temperature. The method includes reconditioning the deposited layer and then resuming treatment of the fluid, wherein reconditioning comprises heating the deposited layer to a second temperature; and cooling the deposited layer to a third temperature at an average cooling rate in the range of up to about 20° C./min.
摘要:
The present invention provides a liquid catalyzing system for aging a liquid, such as alcoholic liquid, vinegar and soy sauce. In the present invention, a plurality of nano metal flakes are adopted as the catalyst and a liquid catalyzing system is particularly designed in the present invention for rapidly aging the liquid. By using the liquid catalyzing system, the liquid can be evenly mixed with the nano metal flakes in a reaction space constructed by a framework and a filter; in addition, a disturb gas is inputted to the reaction space through a gas circulation loop connecting with the framework for treating a liquid flow disturbance to the liquid and the nano metal flakes, so as to accelerate a catalytic reaction resulted from the nano metal flakes to the liquid.
摘要:
A stopper for racking-off operations that comprises a body which is substantially mushroom-shaped, is made of plastics, and is constituted by a tubular cylindrical element adapted to enter the neck of a bottle and close it, and by a head having a larger diameter than the cylindrical element and being monolithic therewith. The stopper for racking-off operations furthermore comprises a container that extends substantially from the head in the opposite direction with respect to the cylindrical element, the container having an opening, at the head, that is connected to a duct passing therethrough and in turn also connected to the internal cavity of the cylindrical element and therefore, when installed, to the inside of the bottle.
摘要:
A method is disclosed of preparing a colorless, clear beer by a method including ultrafiltration and the addition of dextrins, bittering agents and a foam enhancer. Methods of preparing improved nonalcoholic malt beverages and making natural beer foaming components also are disclosed.
摘要:
The components of chill haze in beer can be removed by contacting said beer with a combination of silica hydrogel and gelatin for a time sufficient to complete adsorption of the components and removing said adsorbents from the beer.
摘要:
Inorganic chill-proofing and other agents that are used to process stable beer often contain metals such as iron and copper that are soluble in beer or other beverages. A small addition of magnesium silicate added to said chill-proofing agents, particularly silica hydrogel, substantially averts metal contamination in the beer.
摘要:
A process for stabilizing wine is characterized by:(a) copolymerizing formaldehyde and tannic acid attached to an insoluble carrier to form an immobilized tannic acid composite(b) contacting a wine having components which cause haze formation upon heating with the immobilized tannic acid for a period sufficient to remove the desired amount of haze components; and(c) separating the treated wine from the immobilized tannic acid.
摘要:
Process for production of anionically charged filter media sheet including pretreatment of filter elements with cationic charge modifier, preferably employing inorganic colloidal silica charge modifiers. The resulting filters are used for the removal of haze or haze formers from beverages.
摘要:
The present invention provides an improved process for increasing the chill haze stability of aqueous liquids derived from fruits and vegetables, (e.g., beer, wine, fruit juices, vinegar, etc.) by using one or more haze control agents in a precoat or after precoat layer in the filter media used to filter the liquid and by adding one or more haze control agents as a body feed upstream of the filter. In a preferred embodiment one or more haze control agents are also added in ruh storage at a time in the process significantly before the filtration step. This improved process permits the beverage to be packaged immediately after filtration, thus eliminating the time consuming and space consuming storage following filtration normally required by conventional chill haze control techniques.
