Sanitary stainless steel screw pump

1. Abstract

(1). Single screw pump used to deliver grain, malt and waste wine

After breaking the malt and grain in a breaker, single screw pump mounted at the bottom of the breaker will deliver the malt slurry into a store tank. Then add hot water into the mixture of crashed grain and malt, and malt slurry is made. The aim is to remove the starch in the grain at the most suitable temperature to bring the enzymes into full play. Afterwards, the made-up malt slurry is conveyed into a purifier (strainer), the insoluble malt has been separated here, while the malt slurry has been purified, the glutinous and abrasive waste wine lees and other impurities will be conveyed with single screw pump.

(2). Single screw pump used to deliver malt after steaming and boiling

During the process of steaming and boiling, add hop into the container to prevent the activities of bacteria, to increase the peculiar bitter taste of the beer, and to prolong the period of guaranteeing quality at the same time for benefiting digestion. Then apply single screw pump to convey the steamed and boiled malt extract to next process of separation.

(3). Single screw pump used to deliver hot sludge, diatomite and beer

The malt extract here still contains some impurities needing to separate; the device here applied for this is a cyclone. The subsided impurities is hot slurry with high temperature, it is the most suitable to apply single screw pump to convey such media. When the malt extract is feeding into a heat exchanger, it will be cooled to 4-7 here and become the alleged cold slurry, which will be pumped into a flotation tank, here applying screw pump to feed ferment in fixed amount into store tanks and staying there for about 9-24 days. During the period, the taste of beer is gradually becoming ripe and carbon oxide produced. Afterwards, through filtration by adding diatomite, the beer is pumped into a pressure store tank, the used diatomite has certain viscosity and corrosion, and it is better to be conveyed by using screw pumps.
