• This chamber is defined between the internal wall of the shutter 6, on the one hand, and the drilling tool 3, (the cup 5 where appropriate) and the shoulder 4, on the other hand, said sealed chamber in communication with the pipe 20 of the tubular body via said at least lateral opening.
• a shutter 6 in addition to its function of shuttering element of the inlet mouth can advantageously allow the implementation of a cleaning and disinfection process.
• the shutter 6 can be screwed to the tubular body, the shutter having an internal thread cooperating with an external thread of the tubular body, at the level of the first end of the tubular body.
• the shutter 6 can be fixed to the tubular body of the device by any type of connector, such as an SMS connector or a CLAMP connector.
• the invention also relates to a method for cleaning and disinfecting the interior surfaces of the drilling tool and the conduit of the tubular body of the discharge device 1 and of the exterior surfaces of the drilling tool of the shoulder or even where appropriate of the bowl of the overflow device of equipment according to the invention.
• This cleaning and disinfection process includes the following steps:
• the shutter 6 is placed covering the drilling tool said shoulder 4 (and where appropriate the cup 5) by forming a sealed chamber 60 for a fluid, said chamber being defined between the shutter, with a on the one hand, and the drilling tool 3, said shoulder 4 (and where appropriate the cup 5) on the other hand, said sealed chamber in communication with the duct 20 of the tubular body via said at least lateral opening 32,
• a disinfectant fluid is injected through the outlet mouth 22 so that the disinfectant fluid circulates, on the one hand, in the duct 20 and the hollow of the drilling tool, coming into contact with the internal walls of the duct 20 and the hollow part of the drilling tool 3, and circulates, on the other hand, in the sealed chamber 60 by coming into contact with the outer walls of the drilling tool 3, and of the shoulder 4 or even the of the cuvette 5.
• the hollow of the drilling tool may have a flat 36 on the underside of the drilling tool, opposite the tip 30, avoiding the retention of products.
• this cleaning and disinfection step can advantageously be simultaneous with the cleaning and / or disinfection of the production unit 7.
• the fluid injection step ensuring the disinfection of the interior surfaces of the piercing tool and of the conduit of the tubular body of the discharge device 1 and of the exterior surfaces of the piercing tool, of the bowl and shoulder is an injection simultaneously ensuring the cleaning of the internal surfaces of the fermentation unit.
• the disinfection of the discharge device is ensured simultaneously with the aid of the cleaning step of the fermentation unit.
• the discharge device will find a particular application for emptying a vacuum packaging containing active dry yeast, for example during the manufacture of beer.
• Production unit such as fermentation unit, 70.
• Enclosure such as fermentation tank,
