摘要:
A steam autoclave (steam sterilization system) has a door for opening and closing an opening that defines the entrance to and exit from a steam sterilization chamber. The door may be latched and locked and pneumatically sealed when in a closed position. Preferably, the door has a convex portion that projects into the sterilization chamber when the door is in a closed position for aiding in providing an even distribution of steam throughout the sterilization chamber during operation of the steam autoclave.

A method for stabilizing of wine or other tartaric acid containing beverages. Separation of dissolved wine lees (tartar and/or calcium tartrate) from the beverage is effected by passing the beverage through a deposit or settling layer containing tartar crystals and/or calcium crystals. The disclosure for carrying out the method includes a heat exchanger, a cooler, a dosing container, a stabilizing unit, and a sheet filter. The stabilizing unit has several filter elements arranged one above the other and spaced with respect to each other.

The system and methods described are directed to a distillation system and method having an evaporator tank with a wall surrounding an interior evaporator tank area. A non-oxidizing gas line is disposed at least partially outside the evaporator tank in communication with the interior evaporator tank area, wherein the non-oxidizing gas line introduces a non-oxidizing gas into the interior evaporator tank; the interior evaporator tank area is generally at or above an ambient atmospheric pressure.
摘要:
A method and an apparatus for continuously separating tartar from wine or grape juice using a draft tube baffled (DTB) crystallizer 2 and a hydrocyclone 3. The DTB crystallizer 2 comprises a vessel 5, a draft tube 6 centered in the body 5, a stirrer and a cooling jacket 16, said stirrer producing a circulation of liquid along the draft tube. A liquid of wine or grape juice is continuously introduced from the bottom of the crystallizer 2 into the crystallizer 2 and entrained in the circulation together with seed crystals at a low temperature to crystallize tartar dissolved in the source liquid. Supernatant source liquid is overflown from the crystallizer 2 and separated by the hydrocyclone 3 into a chemically-stabilized product and a suspension in which a large amount of tartar crystals is contained. The suspension is continuously returned to the crystallizer 2 to keep seed crystals at a desired concentration in the crystallizer 2.

A method of stabilizing must and still and sparkling wines with respect to crystalline precipitation. Seed crystals of potassium hydrogentartrate are added to the products during processing to accelerate crystal growth. Since any calcium ions in the wine affect the crystallization of potassium hydrogentartrate, dipotassium DL-tartrate is also added to precipitate the calcium ions. The wine is cooled in a cooler and the colloids filtered out in a filter before the seed crystals are added and is finally stored at a low temperature in a tank. The precipitated crystals are removed in a hydrocyclone and 80% of them added along with dipotassium DL-tartrate to fresh wine that is to be stabilized. The added crystals are finely milled in colloid mills if necessary. The wine from the hydrocyclone is highly clarified in a centrifugal separator to eliminate any crystals not removed in the hydrocyclone.

摘要:
A process for the sterilization of hermetically sealed containers containing a liquid to be sterilized, comprising transport of the containers to a treatment zone where the containers are immersed in a flux of external fluid, the heating in volume of the liquid to be sterilized by electromagnetic waves at a rate greater than 28° C. per second to a treatment temperature T of between 20° C. and 66° C., agitation of the container during heating of the liquid, and dependant on the value of the treatment temperature T, exposure of the liquid to an alternating electric field in pulses immediately or slightly after heating of the liquid.
摘要:
A process for chill-treating, which is exemplified by a process for preparing a fermented malt beverage wherein brewing materials are mashed with water and the resulting mash is heated and wort separated therefrom. The wort is boiled cooled and fermented and the beer is subjected to a finishing stage, which includes aging, to produce the final beverage. The improvement comprises subjecting the beer to a cold stage comprising rapidly cooling the beer to a temperature of about its freezing point in such a manner that ice crystals are formed therein in only minimal amounts. The resulting cooled beer is then mixed for a short period of time with a beer slurry containing ice crystals, without any appreciable collateral increase in the amount of ice crystals in the resulting mixture. Finally, the so-treated beer is extracted from the mixture.
