Abstract
Abstract A dosing system for continuously dosing and dispensing the respective quantities of auxiliary filtering substances to be added in connection with a settling filtration to a cloudy liquid, especially beer, for the cooling and yeast sediments, according to which for dispensing an auxiliary filtering substance for the cooling sediments as well as an auxiliary filtering for the yeast sediment there is provided one dosing device each equipped with a flow meter while both devices which are directly connected to the cloudy liquid conveying conduit are preceded by a flow meter and a device for measuring the total cloudiness of the liquid and by a measuring device provided with a heating zone for measuring the yeast sediment in the cloudy liquid conveying conduit. The dosing installation includes a control device for controlling the dosing devices in conformity with the cloudiness measured by the respective devices.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
270 words
A dosing system for continuously dosing and dispensing the respective quantities of auxiliary filtering substances to be added in connection with a settling filtration to a cloudy liquid, especially beer, for the cooling and yeast sediments, which in-cludes: first and second dosing means for respectively dosing different auxiliary filtering substances for the cooling sediments and the yeast sediments, first and second flow meters respectively associated with said first and second dosing means, sediment con-duit means adapted to be connected to a settling filter, first and second conduit means being connected to said sediment conduit means, a third flow meter and a cloudiness gauge for the respective total sediment and a cloudiness gauge for the respective yeast sediment, said last mentioned gauge including a heating zone, said third flow meter and said gauges being in direct communication with said sediment conduit means and preceding the connection of said first and second dosing means with said second conduit means when looking in the direction of flow in said sediment conduit means, and control means associated with said gauges and said third flow meter and also with said dosing means, said control means including a function generator comprising a subtraction stage and two multiplication stages, one of said multiplication stages being connected to said subtraction stage and also including two rated value - actual value comparing stages respectively connected to said two multiplication stages, said two gauges being connected to said subtraction stage and said third flow meter being connected to said multiplication stages while said first and second flow meters are respectively connected to said rated value - actual value comparing stages.
Claim 2
Dependent Claim
270 words
A dosing system for continuously dosing and dispensing the respective quantities of auxiliary filtering substances to be added in connection with a settling filtration to a cloudy liquid, especially beer, for the cooling and yeast sediments, which in-cludes: first and second dosing means for respectively dosing different auxiliary filtering substances for the cooling sediments and the yeast sediments, first and second flow meters respectively associated with said first and second dosing means, sediment con-duit means adapted to be connected to a settling filter, first and second conduit means being connected to said sediment conduit means, a third flow meter and a cloudiness gauge for the respective total sediment and a cloudiness gauge for the respective yeast sediment, said last mentioned gauge including a heating zone, said third flow meter and said gauges being in direct communication with said sediment conduit means and preceding the connection of said first and second dosing means with said second conduit means when looking in the direction of flow in said sediment conduit means, and control means associated with said gauges and said third flow meter and also with said dosing means, said control means including a function generator comprising a subtraction stage and two multiplication stages, one of said multiplication stages being connected to said subtraction stage and also including two rated value - actual value comparing stages respectively connected to said two multiplication stages, said two gauges being connected to said subtraction stage and said third flow meter being connected to said multiplication stages while said first and second flow meters are respectively connected to said rated value - actual value comparing stages.
Claim 3
Dependent Claim
48 words
A dosing system according to claim 1, which includes throttling means arranged within said sediment conduit means and preceding said third flow meter when looking in the direction of flow in said sediment conduit means, and by-pass means by-passing said throttling means and having said gauges arranged therein.
Claim 4
Dependent Claim
74 words
A dosing system according to claim 1, in which the cloudiness gauge for the total sediment and the cloudiness gauge for the yeast settlement are spaced from the areas of connection of said first and second dosing means with said sediment conduit means by a distance approximately equalling the product of the velocity of the cloudy liquid set for constant flow speed and the maximum adjusting time for said first and second dosing means.
