Abstract
To provide a suitable filling atmosphere around a produce filling pipe on a packing machine and to make possible a rational, accurate cleaning of the filling pipe of the machine without having to dismantle and disassemble the filling pipe at a normal stoppage of the machine, the filling pipe is surrounded by a permanent tubular casing whose lower end is adapted so that it can be closed for cleaning with the aid of a detachable lid to form a container enclosing the filling pipe. The filling pipe, via a connecting means at the upper end of the casing, can be joined to an outer flow system to allow circulation of a cleansing agent.
Claims7
An arrangement on a packing machine comprising a product filling pipe having an opening at one end;
- a tubular casing element arranged around said product filling pipe so as to form a free flow space between the product filling pipe and the casing element, said casing element having a connecting means;
- an outer duct being in fluid communication to an outer duct for flowing fluid through said connecting means arranged on the casing element, said casing element having an end facing said opening of the product filling pipe, said end closable by a detachable lid element to form a container that substantially encloses the product filling pipe to allow circulation of a cleansing fluid, said outer duct being connected to an air supply duct by a T-shaped junction piece, said air supply duct being connected to a blower having an air intake, a heat exchanger and a sterile filter device, said air supply duct having a valve for selectively opening or closing a fluid communication between said air supply duct and said outer duct.
An arrangement on a packing machine comprising:
- a product filling pipe having an opening at one end;
- a tubular casing surrounding said product filling pipe and spaced outwardly from said filling pipe to form a fluid passage between said product filling pipe and said casing, said casing having an end adjacent said opening of said product filling pipe;
- lid means for selectively enclosing said product filling pipe in said casing during circulation of a cleansing fluid;
- valve means for controlling a fluid flow to said casing;
- conduit means for providing fluid communication between said casing and said valve means;
- a source of air under pressure communicating with said valve means whereby air under pressure is supplied through said valve means to said fluid passage for sterilization around said filling pipe opening when said valve means is open;
- and
- a source of cleansing fluid communicating with said fluid passage when said valve means is closed.
