Abstract
The invention concerns an apparatus for and a method of treating a plurality of zones of a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced into pipes conveying the carrier liquid to each zone as discrete slugs, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency. Preferably the treatment liquid is applied to all zones from a single source, and the slugs, upon discharge at least at one zone, remain substantially concentrated. The invention particularly concerns the lubricating of conveyors as in bottling lines.
Claims19
A method of treating a plurality of zones of a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced as discrete slugs, into pipes conveying the carrier liquid to each zone, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency.
A method of treating a plurality of zones of a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced as discrete slugs, into pipes conveying the carrier liquid to each zone, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency, the treatment liquid being applied to all zones from a single source, said slugs, upon discharge at least at one zone, remaining substantially concentrated, the peak concentration of the slugs at the discharge being at least twice, preferably at least five times, the concentration of a homogeneous solution of the treatment liquid in the carrier liquid in the pipe.
A method of treating a plurality of zones of a processing line with liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced as discrete slugs into pipes conveying the carrier liquid to each zone, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency, the treatment liquid being applied to all zones from a single source, each slug being buffered from the carrier liquid by gas.
An apparatus for treating a plurality of zones in a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, the apparatus comprising:
- a source of treatment liquid;
- a source of carrier liquid;
- a plurality of pipes conveying the carrier liquid to each zone;
- and
- means for introducing the treatment liquid into each pipe in discrete slugs of a selectively variable volume or at a selectively variable frequency.
A apparatus for treating a plurality of zones in a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, the apparatus comprising:
- a source of treatment liquid;
- a source of carrier liquid;
- a plurality of pipes conveying the carrier liquid to each zone;
- and
- means for introducing the treatment liquid into each pipe in discrete slugs of a selectively variable volume or at a selectively variable frequency;
- the source of treatment liquid being a single source for all zones;
- the introducing means comprising a branch for the treatment liquid which intrudes into an angle in the pipe for the carrier liquid, and valves controlling the flow of the treatment and carrier liquid.
